Timberline Vegetation on Mountains
The transition from forest to treeless tundra on a mountain slope is often a dramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.
The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics. Timberline trees are normally evergreens, suggesting that these have some advantage over deciduous trees (those that lose their leaves) in the extreme environments of the upper timberline. There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.
At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater heights in the valleys. This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover. As the snow is deeper and lasts longer in the valleys, trees tend to attain greater heights on the ridges, even though they are more exposed to high-velocity winds and poor, thin soils there. In the tropics, the valleys appear to be more favorable because they are less prone to dry out, they have less frost, and they have deeper soils.
There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role. Too much snow, for example, can smother trees, and avalanches and snow creep can damage or destroy them. Late-lying snow reduces the effective growing season to the point where seedlings cannot establish themselves. Wind velocity also increases with altitude and may cause serious stress for trees, as is made evident by the deformed shapes at high altitudes. Some scientists have proposed that the presence of increasing levels of ultraviolet light with elevation may play a role, while browsing and grazing animals like the ibex may be another contributing factor. Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.
Above the tree line there is a zone that is generally called alpine tundra. Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. Some plants can even survive in favorable microhabitats above the snow line. The highest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. At this great height, rocks, warmed by the sun, melt small snowdrifts.
The most striking characteristic of the plants of the alpine zone is their low growth form. This enables them to avoid the worst rigors of high winds and permits them to make use of the higher temperatures immediately adjacent to the ground surface. In an area where low temperatures are limiting to life, the importance of the additional heat near the surface is crucial. The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover. In the equatorial mountains the low growth form is less prevalent.
Paragraph 1: The transition from forest to treeless tundra on a mountain slope is often adramatic one. Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses. This rapid zone of transition is called the upper timberline or tree line. In many semiarid areas there is also a lower timberline where the forest passes into steppe or desert at its lower edge, usually because of a lack of moisture.

3. Which of the following can be inferred from paragraph 1 about both the upper and lower timberlines?
○Both are treeless zones.
○Both mark forest boundaries.
○Both are surrounded by desert areas.
○Both suffer from a lack of moisture.
Paragraph 2: The upper timberline, like the snow line, is highest in the tropics and lowest in the Polar Regions. It ranges from sea level in the Polar Regions to 4,500 meters in the dry subtropics and 3,500-4,500 meters in the moist tropics. Timberline trees are normally evergreens, suggesting that these have some advantage over deciduous trees (those that lose their leaves) in the extreme environments of the upper timberline. There are some areas, however, where broadleaf deciduous trees form the timberline. Species of birch, for example, may occur at the timberline in parts of the Himalayas.

○They cannot grow in cold climates.
○They do not exist at the upper timberline.
○They are less likely than evergreens to survive at the upper timberline.
○They do not require as much moisture as evergreens do.
Paragraph 3: At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater heights in the valleys. This is because middle- and upper- latitude timberlines are strongly influenced by the duration and depth of the snow cover. As the snow is deeper and lasts longer in the valleys, trees tend to attain greater heights on the ridges, even though they are more exposed to high-velocity winds and poor, thin soils there. In the tropics, the valleys appear to be more favorable because they are less prone to dry out, they have less frost, and they have deeper soils.

○Tree growth lasts longer in those latitudes than it does in the tropics.
Paragraph 4：There is still no universally agreed-on explanation for why there should be such a dramatic cessation of tree growth at the upper timberline. Various environmental factors may play a role. Too much snow, for example, can smother trees, and avalanches and snow creep can damage or destroy them.

Probably the most important environmental factor is temperature, for if the growing season is too short and temperatures are too low, tree shoots and buds cannot mature sufficiently to survive the winter months.
9. Which of the sentences below best express the essential information in the highlighted sentence in the passage? In correct choices change the meaning in important ways or leave out essential information.
○Because of their deformed shapes at high altitudes, trees are not likely to be seriously harmed by the strong winds typical of those altitudes.
○As altitude increases, the velocity of winds increase, leading to a serious decrease in the number of trees found at high altitudes.
○The deformed shapes of trees at high altitudes show that wind velocity, which increase with altitude, can cause serious hardship for trees.
○Increased wind velocity at high altitudes deforms the shapes of trees, and this may cause serious stress for trees.
10. In paragraph 4, what is the author's main purpose in the discussion of the dramatic cessation of tree growth at the upper timberline?
○To argue that none of several environment factors that are believed to contribute to that phenomenon do in fact play a role in causing it.
○To argue in support of one particular explanation of that phenomenon against several competing explanations
○To explain why the primary environmental factor responsible for that phenomenon has not yet been identified
○To present several environmental factors that may contribute to a satisfactory explanation of that phenomenon
Paragraph 6: The most striking characteristic of the plants of the alpine zone is their low growth form. This enables them to avoid the worst rigors of high winds and permits them to make use of the higher temperatures immediately adjacent to the ground surface. In an area where low temperatures are limiting to life, the importance of the additional heat near the surface is crucial. The low growth form can also permit the plants to take advantage of the insulation provided by a winter snow cover. In the equatorial mountains the low growth form is lessprevalent.
11. The word "prevalent" in the passage is closest in meaning to
○predictable
○widespread
○successful
○developed
12. According to paragraph 6, all of the following statements are true of plants in the alpine zone EXCEPT:
○Because they are low, they are less exposed to strong winds.
○Because they are low, the winter snow cover gives them more protection from the extreme cold.
○In the equatorial mountains, they tend to be lower than in mountains elsewhere.
○Their low growth form keeps them closer to the ground, where there is more heat than further up.
Paragraph 5: Above the tree line there is a zone that is generally called alpine tundra. █Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. █Some plants can even survive in favorable microhabitats above the snow line.

山上树带界线的植被
通常从山坡上的森林到没有树的苔原是一种非常戏剧化的转变。在一个垂直距离只有几十米的地方，树木这种生命形式就消失了，取而代之的是低矮的灌木、草本植物和牧草。这种快速过渡的区域被称为上行树带界线或林木线。在许多干旱的地区存在着下行树带界线，在这里由于缺乏水分森林变成干草原，甚至在最下端会出现沙漠。
上行树带界线，和雪线一样，在热带最高，在极地最低。从极地地区的海平面到干燥的亚热带地区的海拔4 500米处以及潮湿的热带地区海拔3 500米至4 500米处都有上行树带界线。树带界线内通常是常绿树，它们和处于上行树带界线处极端恶劣环境中生长的落叶树木相比，具有一定的优势。然而，在部分地区也有由落叶阔叶林组成的树带界线。例如，在喜马拉雅的部分地区，桦树就在树带界线上。
上行树带界线的树木开始扭曲和变形，尤其在中高纬度地区的树木，这些地区的树木往往会在山脊上长得更高，而在热带地区的树木则在山谷里长得更高;因为中高纬度地区树带界线受积雪覆盖时间和深度的影响很大。由于山谷中积雪覆盖较厚且持续时间很长，树木即便是生长在大风和贫瘠的土地里，也往往会在山脊上长得更高。在热带地区山谷里更有利于生长，因为山谷不易干涸、很少结霜，并且有更深的土壤。
目前还没有一个普遍认同的解释来说明为什么会在树带界线上出现树木停止生长这种戏剧化的现象。多种环境因素都起到作用，例如，积雪过多会让树木透不过气，雪崩和雪移能摧毁树木;长时间积雪缩短了有效生长季节的时间，树苗无法生长;另外，风速会随着海拔的升高而增加，增加树木承受的压力，很明显，正是这种风速带来的压力导致树木在高纬度地区发生变形。一些科学家提出，随着海拔的上升而不断增强的紫外线、野生山羊等动物的放养，都是导致树带界线形成的因素。或许最重要的环境因素是温度，因为如果生长季节太短并且气温太低，树芽和树苗都无法充分地成长而存活过冬季。
在林木线之上有一个称为高山苔原的地带。由于紧挨着树带界线，苔原上都是矮灌木、草本植物和牧草。随着海拔的增加，物种的数量和多样性会逐渐减少，直到出现大量空地伴着零星的苔藓和地衣这样的伏地垫状植物。有些植物甚至可以在雪线以上有利的微环境中生存，世界上海拔最高的植物是出现在喜马拉雅山上6 100百米的马卡鲁峰。在这个高度上，被阳光温暖过的岩石可以将 小雪 堆融化。
高山植物最突出的特点是其低矮的生长形态。这种特点使他们能够避开大风最强势的势头，并且有助于他们利用紧邻地 面相 对较高的温度。在这样一个低温限制生命的地区，地表提供的额外温度是至关重要的。低矮的生长形态也可以帮助植物充分利用冬季积雪所提供的保温环境。在赤道区的山脉上低矮的生长形态并不常见。

The Geologic History of the Mediterranean
In 1970 geologists Kenneth J. Hsu and William B.F. Ryan were collecting research data while aboard the oceanographic research vessel Glomar Challenger. An objective of this particular cruise was to investigate the floor of the Mediterranean and to resolve questions about its geologic history. One question was related to evidence that the invertebrate fauna (animals without spines) of the Mediterranean had changed abruptly about 6 million years ago. Most of the older organisms were nearly wiped out, although a few hardy species survived. A few managed to migrate into the Atlantic. Somewhat later, the migrants returned, bringing new species with them. Why did the near extinction and migrations occur?
Another task for the Glomar Challenger's scientists was to try to determine the origin of the domelike masses buried deep beneath the Mediterranean seafloor. These structures had been detected years earlier by echo-sounding instruments, but they had never been penetrated in the course of drilling. Were they salt domes such as are common along the United States Gulf Coast, and if so, why should there have been so much solid crystalline salt beneath the floor of the Mediterranean?
With question such as these clearly before them, the scientists aboard the Glomar Challenger processed to the Mediterranean to search for the answers. On August 23, 1970, they recovered a sample. The sample consisted of pebbles of hardened sediment that had once been soft, deep-sea mud, as well as granules of gypsum and fragments of volcanic rock. Not a single pebble was found that might have indicated that the pebbles came from the nearby continent. In the days following, samples of solid gypsum were repeatedly brought on deck as drilling operations penetrated the seafloor. Furthermore, the gypsum was found to possess peculiarities of composition and structure that suggested it had formed on desert flats. Sediment above and below the gypsum layer contained tiny marine fossils, indicating open-ocean conditions. As they drilled into the central and deepest part of the Mediterranean basin, the scientists took solid, shiny, crystalline salt from the core barrel. Interbedded with the salt were thin layers of what appeared to be windblown silt.
The time had come to formulate a hypothesis. The investigators theorized that about 20 million years ago, the Mediterranean was a broad seaway linked to the Atlantic by two narrow straits. Crustal movements closed the straits, and the landlocked Mediterranean began to evaporate. Increasing salinity caused by the evaporation resulted in the extermination of scores of invertebrate species. only a few organisms especially tolerant of very salty conditions remained. As evaporation continued, the remaining brine (salt water) became so dense that the calcium sulfate of the hard layer was precipitated. In the central deeper part of the basin, the last of the brine evaporated to precipitate more soluble sodium chloride (salt). Later, under the weight of overlying sediments, this salt flowed plastically upward to form salt domes. Before this happened, however, the Mediterranean was a vast desert 3,000 meters deep. Then, about 5.5 million years ago came the deluge. As a result of crustal adjustments and faulting, the Strait of Gibraltar, where the Mediterranean now connects to the Atlantic, opened, and water cascaded spectacularly back into the Mediterranean. Turbulent waters tore into the hardened salt flats, broke them up, and ground them into the pebbles observed in the first sample taken by the Challenger. As the basin was refilled, normal marine organisms returned. Soon layer of oceanic ooze began to accumulate above the old hard layer.
The salt and gypsum, the faunal changes, and the unusual gravel provided abundant evidence that the Mediterranean was once a desert.

参考翻译：地中海的地质历史
1970年，地理学家Kenneth J. Hsu 和 William B.F. Ryan在海洋调查船Glomar Challenger号上收集调研资料。这次特别巡航的一个目的是调查地中海的地层以及解决关于其地质历史的问题。其中一个问题是有关地中海地区无脊椎动物(没有脊椎的动物)于600万年前发生剧变的证据。大部分更加古老的生物都几乎灭绝了，尽管一些顽强的种类得以生存。很少的一些动物成功地迁移到了大西洋。不久后，这些动物又回来了，并带回来新的物种。为什么这次较近的动物灭绝和迁移会发生呢?
Glomar Challenger号上科学家们的另一个任务是尝试去确定深埋在地中海海底穹顶状巨块的起源。这些结构在早些年被回声探测器探测过，但是它们从未被钻探过。它们是像美国墨西哥海湾海岸一带的含盐穹顶状巨块吗?如果是的话，为什么在地中海海底之下会有这么多固体的结晶盐呢?
带着这些清楚摆在他们面前的问题，科学家们登上Glomar Challenger号前往地中海寻找答案。1970年8月23日，他们找到了一个样本。这个样本由石膏块和火山岩碎块组成。周围没有发现一块能说明这些小石头来自附近的大陆。接下来的日子里，随着海底岩层钻探实验的进行，固体石膏样本被不断地放在甲板上。而且，这些膏状物的组成和结构特性表明它们形成于沙漠。在石膏层上下的沉积物中包含了微小的海洋生物化石，说明了这是开放性的海洋环境。当钻到地中海盆地中心的最深处时，科学家们从钻管中获得了坚实的、光亮的结晶盐。跟结晶盐嵌在一起的薄层像是被风吹起的泥沙层。
时间阐明了一个假设。调查者们构思了这样的理论：大约2 000万年前，地中海是一条宽阔的航道，它通过两条狭窄的海峡与大西洋连接。地壳运动封闭了海峡，被陆地包围的地中海也开始蒸发。由蒸发引起的越来越高的盐度造成无脊椎动物种类的灭绝。只有一些能抵抗高盐度条件的物种保留下来。随着蒸发的继续进行，盐水浓度太高以致硬地层的硫酸钙发生沉淀。在盆地的中间深处，剩余盐水的持续蒸发形成更多的可溶的氯化钠(盐)。后来，在上层沉淀物的重压下，盐向上形成了含盐的圆顶。然而在这之前，地中海是一个3 000米深的大沙漠。然后，550万年前发生了洪水。作为地壳调整和断层作用的结果，现在连接地中海和大西洋的直布罗陀海峡打开了，水流像瀑布一样壮观地涌回地中海。湍急的水流冲击并摧毁了坚硬的含盐层，把它们磨成了Challenger号获得的第一份样本中人们所观察到的鹅卵石。随着盆地的填充，普通的海洋生物又回来了。不久后海洋软泥层开始在原先的硬地层上堆积。
盐、石膏、动物区系的变更，还有不寻常的沙砾层都为地中海曾经是片沙漠的理论提供了充分的证据。

为了帮助大家备考托福阅读，提高成绩，下面我给大家带来托福阅读TPO21(试题+答案+译文)第一篇:Geothermal Energy，希望大家喜欢！
托福阅读原文
【1】Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes. It can also be harnessed to drive electric generators and heat homes. Geothermal energy becomes available in a practical form when underground heat is transferred by water that is heated as it passes through a subsurface region of hot rocks (a heat reservoir) that may be hundreds or thousands of feet deep. The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.
【2】By far the most abundant form of geothermal energy occurs at the relatively low temperatures of 80° to 180° centigrade. Water circulated through heat reservoirs in this temperature range is able to extract enough heat to warm residential, commercial, and industrial spaces. More than 20,000 apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin. Iceland sits on a volcanic structure known as the Mid-Atlantic Ridge. Reykjavik, the capital of Iceland, is entirely heated by geothermal energy derived from volcanic heat.
【3】Geothermal reservoirs with temperatures above 180° centigrade are useful for generating electricity. They occur primarily in regions of recent volcanic activity as hot, dry rock; natural hot water; or natural steam. The latter two sources are limited to those few areas where surface water seeps down through underground faults or fractures to reach deep rocks heated by the recent activity of molten rock material. The world's largest supply of natural steam occurs at The Geysers, 120 kilometers north of San Francisco, California. In the 1990s enough electricity to meet about half the needs of San Francisco was being generated there. This facility was then in its third decade of production and was beginning to show signs of decline, perhaps because of over development. By the late 1990s some 70 geothermal electric-generating plants were in operation in California, Utah, Nevada, and Hawaii, generating enough power to supply about a million people. Eighteen countries now generate electricity using geothermal heat.
【4】Extracting heat from very hot, dry rocks presents a more difficult problem: the rocks must be fractured to permit the circulation of water, and the water must be provided artificially. The rocks are fractured by water pumped down at very high pressures. Experiments are under way to develop technologies for exploiting this resource.
【5】Like most other energy sources, geothermal energy presents some environmental problems. The surface of the ground can sink if hot groundwater is withdrawn without being replaced. In addition, water heated geothermally can contain salts and toxic materials dissolved from the hot rock. These waters present a disposal problem if they are not returned to the ground from which they were removed.
【6】The contribution of geothermal energy to the world's energy future is difficult to estimate. Geothermal energy is in a sense not renewable, because in most cases the heat would be drawn out of a reservoir much more rapidly than it would be replaced by the very slow geological processes by which heat flows through solid rock into a heat reservoir. However, in many places (for example, California, Hawaii, the Philippines, Japan, Mexico, the rift valleys of Africa)the resource is potentially so large that its future will depend on the economics of production. At present, we can make efficient use of only naturally occurring hot water or steam deposits. Although the potential is enormous, it is likely that in the near future geothermal energy can make important local contributions only where the resource is close to the user and the economics are favorable, as they are in California, New Zealand, and Iceland. Geothermal energy probably will not make large-scale contributions to the world energy budget until well into the twenty-first century, if ever.

13. Look at the four squares [■] that indicate where the following sentence could be added to the passage. Where would the sentence best fit? Click on a square to add the sentence to the passage. In either case, the heated water will usually be under considerable pressure, and so may have a temperature that is well above its sea-level boiling point of 100° centigrade.
Earth's internal heat, fueled by radioactivity, provides the energy for plate tectonics and continental drift, mountain building, and earthquakes. It can also be harnessed to drive electric generators and heat homes. Geothermal energy becomes available in a practical form when underground heat is transferred by water that is heated as it passes through a subsurface region of hot rocks (a heat reservoir) that may be hundreds or thousands of feet deep. ■【A】The water is usually naturally occurring groundwater that seeps down along fractures in the rock; less typically, the water is artificially introduced by being pumped down from the surface. ■【B】The water is brought to the surface, as a liquid or steam, through holes drilled for the purpose.■【C】
By far the most abundant form of geothermal energy occurs at the relatively low temperatures of 80° to 180° centigrade. ■【D】Water circulated through heat reservoirs in this temperature range is able to extract enough heat to warm residential, commercial, and industrial spaces. More than 20,000 apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin. Iceland sits on a volcanic structure known as the Mid-Atlantic Ridge. Reykjavik, the capital of Iceland, is entirely heated by geothermal energy derived from volcanic heat.
14. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.
Heat reservoirs in the form of hot rock far beneath Earth's surface are a potential source of usable geothermal energy.
A.Heat reservoirs with a temperature from 80° to 180° centigrade can be used, as in France and Iceland, to heat buildings.
B.A number of countries now use geothermal reservoirs that contain water or steam above 180° centigrade to generate electricity.
C.Most heat reservoirs with a temperature above 180° centigrade cannot be used for energy because they are usually too close to recent volcanic activity.
D.The sinking of land above heat reservoirs and other environmental problems arise when water is pumped into a heat reservoir under high pressure.
E.Experiments are under way to determine if geothermally heated waters could be used as a source of certain minerals that have been dissolved out of hot rocks deep within Earth.
F.A number of issues, including how to extract heat from reservoirs that do not have a natural supply of water, will significantly limit the use of geothermal energy for the foreseeable future.
托福 阅读答案
1.细节题，问radioactivity和steam的关系，所以找双关键词，分别定位至本段第一句和最后一句，第一句说radioactivity提供了地球的内热，最后一句说水变成蒸汽到达地表，水受热才能蒸汽，而这份热量是geothermal energy提供的，这就是二者的关系，所以答案是C。A的水暴露在radioactive underground时候steam产生没说;B水变成radioactive没说;D的radioactivity产生蒸汽更不靠谱。
2.practical实际的，可用的，答案是A的usable，此题简单，B plentiful大量的、C economical节省的和D familiar熟悉的，完全不对。
3.abundant大量的，充足的，所以答案是C的plentiful，我怀疑这个题的选项是不是跟上一道题弄混了，待定。不过C肯定是对的。此题也较简单，其他答案完全不沾边，不会的各位最好认真背单词了。
4.以80到180度做关键词定位至第一句，说最丰富的geothermal energy是在80到180度范围内的，所以同义替换是B的more common than higher temperature。A的international control原文没说;C与本段第二句说反;D在本段没提，但下一段说高于180度的可以用来发电，所以D说反了。
5.又是一个问两者关系的题，找双关键词，定位至第三句，说natural hot water和natural steam仅存在于那些地点，地表水通过fault或者fracture渗到地下，碰到被加热的blabla，答案明显是D。A说fault使heat跑上来，和原文的方向说反了，原文是水跑下去;B说steam创造了fault完全不靠谱;C的steam被trap原文没说。
6.修辞目的题，先读例子所在句，只是细节，按照常规应该往前看，但前一句已经在上题看过，与答案无关，所以往下看，而且看下一句另外一个原因是因为代词this，下句说G经历了30年的运作，已经显示衰败迹象，可能是因为过度开发，所以答案是C，A和B的内容原文没提;D本身也是个细节。
7.此题用排除法更快，A与第二段首句说反，错;第二段只是说geothermal energy可以用来加热building，没说most，B错;C和D都可以从两段的首句看出来，第二段说最多的是在80到180度，第三段说发电需要180度以上，所以发电比别的温度高，D对，C说反。
8.整个问题做关键词定位至第一句，说从hot, dry rock抽热量是特别难的，必须先fracture rock，水也要人工引入，所以答案是A。D没说，B和C原文确实有说，但没有回答为什么难，也就是那种答非所问选项，所以也不对。
9.exploit开发，利用，剥削压榨，所以C的making use of正确。原文说人们正在实践新的技术来怎么样这种资源，B很显然不对，资源如果想加就加那就好了;A定位和D估计数量都太初级了，而且现在的技术就可以定位和算储量，明显不应该是under way。
10.又是一个问两者关系的题，本来应该找双关键词，但这段实在太短，找关键词还不如读完，快速扫完之后发现这两件事情都是由于开采地下水引起的问题，而且最后一句说如果不把地下水补充回去就会有问题，所以答案是A。两个问题之间是并列关系，既没有比较也没有因果，所以B和C都不对;D的dissolved溶解原文没说，也不对。
11.原句的结构是geothermal energy是不renewable的，因为blabla，所以前面的结果一定要有，A和D排除;原句的原因中有一个比较，说draw out比replace的快，C重现了这个比较，B没有，所以正确答案是C。
12.修辞目的题，先读细节所在句，说在这些资源如此充足的地方，资源的利用前景取决于economies of production生产经济，四个答案中只有A提到了开采是否划算的问题，所以答案是A。B和D原文直接没说;C跑到最后一句去了，跟例子也没什么关系，注意倒数第二句MS也有例子，但是题目问的不是那个。
13.这道题有一个过渡点就够了，in either case说明正确插入点之前必须有两种情况，直接确定B，因为之前有usually和less typically两种情况。
14.Heat选项对应原文第二段，正确;注意不要因为温度和国家把这个选项当成细节，即使当成细节，也可以凭其他选项都不对的排除法解决。Most heat选项与原文第三段首句说反，不选。Experiments选项MS对应原文第四段最后一句，但原文说的是利用热能，不是矿物，所以这个选项不选。A number of countries选项对应原文第三段首句，正确;注意不要因为温度把这个选项当成细节。The sinking选项不知所云，好像有语法错误，不知道是不是我的TPO版本问题，但即使这个选项语法没问题，说的也应该是第五段的细节，或者是干脆没说，所以不选。A number of issues选项对应原文第六段，正确。
托福阅读译文
【1】地球内部因放射产生的热量为板块运动、大陆漂移、造山运动和地震提供了能量。这种热量还可以用来驱动发电机发电以及为家庭供暖。水流经地表下可能几百甚至几千英尺深的热岩区域(一种热储)被加热，当被加热的水将热量传递出来时，地热能就可以实际形式加以利用了。这些水通常是沿着岩石的断面下渗的天然地下水，少数情况下是人为从地表泵入的水。通过为了采集地热能所钻的孔，这些水会以液体或蒸汽的形式被带到地表。
【2】到目前为止，最丰富的地热能形式介于相对较低的80到180摄氏度的温度。在此温度范围内的热储内循环的水可以提取出足够的热量供居住区、商业区和工业区取暖。目前在法国有20 000间以上的公寓是由温暖的地下水供暖的，这些地下水来自位于巴黎附近叫做巴黎盆地的地质构造的热储。冰岛位于一个被称为是大西洋中脊的火山构造之上。冰岛的首都雷克雅维克完全是用火山热产生的地热能供暖的。
【3】温度高于180摄氏度的地热储集层可用来发电。这类地热储集层主要位于有近期火山活动的区域，以干热的岩石、天然热水或天然蒸汽的形式存在。后两种形式的储集层局限于少数区域，在这些区域，地表水通过地下断层或断裂渗入到被近期的熔岩活动加热的深层岩石。世界上最大的天然蒸汽供应位于加州旧金山以北120公里处的盖沙斯。二十世纪九十年代，那里产出的电能足够满足旧金山半数的需求。当时该电厂已经有三十个年头了，开始显示出发电量下降的迹象，这可能是由于过度的开发所致。到二十世纪九十年代末，加州、犹他州、内华达州和夏威夷约有70个地热发电厂在运转，产生的电能足够满足一百万人的需求。目前有18个国家在利用地热能发电。
【4】要从极干热的岩石中提取热量存在一个更大的难题：岩石需要有裂缝才能让水流通，而且水必须是人工提供的。通过泵入高压水可以将岩石断裂。开发利用此能源的技术的实验正在进行之中。
【5】就像大多数 其它 能源一样，地热能也具有一些环境问题。如果抽取地下热水而又不泵回，地表就会下沉。此外，地热加热的水含有从热岩中溶出的盐分和有毒物质。这些水如果不能被输送回抽取的地方，将会产生处理方面的问题。
【6】地热能对世界能源未来的贡献是难以估量的。地热能在某种意义上讲是不可再生的，因为多数情况下，与热量流经坚硬的岩石到达热储这个极为缓慢的地质作用的更新速度相比，从热储提取热量的速度要快得多。不过，在很多地区(例如加州、夏威夷、菲律宾、日本、墨西哥、非洲的裂谷)，这种能源可能非常可观，它的前景将取决于经济的生产。目前，我们只能有效地利用天然形成的热水或蒸汽形式的地热能。尽管潜能巨大，近期之内地热能可能只能对毗邻用户以及经济状况良好的地区做出重要的局部贡献，就像在加州、新西兰和冰岛地区的情况一样。如果可能的话，地热能估计要到二十一世纪才能对世界的能源预算做出大的贡献。

托福阅读原文
China has one of the world's oldestcontinuous civilizations—despite invasions and occasional foreign rule. Acountry as vast as China with so long-lasting a civilization has a complexsocial and visual history, within which pottery and porcelain play a majorrole.
The function and status of ceramics inChina varied from dynasty to dynasty, so they may be utilitarian, burial,trade-collectors', or even ritual objects, according to their quality and theera in which they were made. The ceramics fall into three broadtypes—earthenware, stoneware, and porcelain—for vessels, architectural itemssuch as roof tiles, and modeled objects and figures. In addition, there was animportant group of sculptures made for religious use, the majority of whichwere produced in earthenware.
The earliest ceramics were fired toearthenware temperatures, but as early as the fifteenth century B.C.,high-temperature stone wares were being made with glazed surfaces. During theSix Dynasties period (AD 265-589), kilns in north China were producinghigh-fired ceramics of good quality. White wares produced in Hebei and Henanprovinces from the seventh to the tenth centuries evolved into the highlyprized porcelains of the Song dynasty (AD. 960-1279), long regarded as one ofthe high points in the history of China's ceramic industry. The tradition ofreligious sculpture extends over most historical periods but is less clearlydelineated than that of stone wares or porcelains, for it embraces the oldcustom of earthenware burial ceramics with later religious images andarchitectural ornament. Ceramic products also include lead-glazed tomb modelsof the Han dynasty, three-color lead-glazed vessels and figures of the Tangdynasty, and Ming three-color temple ornaments, in which the motifs wereoutlined in a raised trail of slip—as well as the many burial ceramics producedin imitation of vessels made in materials of higher intrinsic value.
Trade between the West and the settled andprosperous Chinese dynasties introduced new forms and different technologies.One of the most far-reaching examples is the impact of the fine ninth-centuryAD. Chinese porcelain wares imported into the Arab world. So admired were thesepieces that they encouraged the development of earthenware made in imitation ofporcelain and instigated research into the method of their manufacture. Fromthe Middle East the Chinese acquired a blue pigment—a purified form of cobaltoxide unobtainable at that time in China—that contained only a low level ofmanganese. Cobalt ores found in China have a high manganese content, whichproduces a more muted blue-gray color. In the seventeenth century, the tradingactivities of the Dutch East India Company resulted in vast quantities ofdecorated Chinese porcelain being brought to Europe, which stimulated andinfluenced the work of a wide variety of wares, notably Delft. The Chinesethemselves adapted many specific vessel forms from the West, such as bottleswith long spouts, and designed a range of decorative patterns especially forthe European market.
Just as painted designs on Greek pots mayseem today to be purely decorative, whereas in fact they were carefully andprecisely worked out so that at the time, their meaning was clear, so it iswith Chinese pots. To twentieth-centuryeyes, Chinese pottery may appear merely decorative, yet to the Chinese the formof each object and its adornment had meaning and significance. The dragonrepresented the emperor, and the phoenix, the empress; the pomegranateindicated fertility, and a pair of fish, happiness; mandarin ducks stood forwedded bliss; the pine tree, peach, and crane are emblems of long life; and fishleaping from waves indicated success in the civil service examinations. onlywhen European decorative themes were introduced did these meanings becomeobscured or even lost.
From early times pots were used in bothreligious and secular contexts. The imperial court commissioned work and in theYuan dynasty (A.D. 1279-1368) an imperial ceramic factory was established atJingdezhen. Pots played an important part in some religious ceremonies. Longand often lyrical descriptions of the different types of ware exist that assistin classifying pots, although these sometimes confuse an already large andcomplicated picture.

托福 阅读答案
1.status状态，地位，所以B的importance重要性，地位正确。原句说瓷器的作用和什么因朝代而不同，而且之后有解释可能是实用的，用于埋葬的，或者blabla，所以importance能对上。origin起源不可能因为朝代而变化;quality后面有，不应该重复;design与后文的例子对不上
2.问题中的关键词不能用，所以排除法最好。A的dynasty todynasty做关键词定位至第一句，说反，错;B的trade objects和ritual objects做关键词定位至第一句，原文没有比较，错;C的quality做关键词定位至第一句，说根据它们质量决定用来干嘛，所以质量是有变化的，C错;D的religious和earthenware做关键词定位至最后一句，正确
3.evolve进化，演化，所以C的develop正确。原文说七到十世纪的白瓷怎么样成了宋代的很好的瓷，无论从时间上还是后面说的highly prized都证明后面的比前面的好，所以应该是变好的意思，A分开B延伸D消失都没有变好之意
4.原文的主要关系是因果，因果的结果部分包含了一个转折，所以从结构上说只有B和D可能正确。B正确，D错在原文说stoneware和porcelain比religious sculpture清楚，但没说religious sculpture不清楚，错
5.EXCEPT题，排除法。A的high-firedceramics做关键词定位至第二句，原文说good quality, 备选项说poor，反了，错，选;B的Tang and Ming Dynasty做关键词定位至最后一句，正确，不选;C的earthenware和stoneware做关键词定位至第一句，原文说最早的是earthenware，所以比stoneware早，所以C正确，不选;D的Song dynasty做关键词定位至第三句，正确，不选
6.nstigate教唆，鼓动，煽动，所以cause引起正确，注意不要被investigate迷惑。原句说那些陶器非常惹人喜爱，促进了earthenware的发展，也instigate了制陶 方法 的研究，instigate与原文的encourage并列，所以应该是鼓励之意。A提升改善B调查C变窄均不正确
7.以trade of Chineseceramics做关键词定位至倒数第二句，问结果，所以应该关注result in之后的内容，说大量的Chinese porcelain到了欧洲，影响了一系列ware，接着又说会专门为欧洲市场做一些ware，所以C正确;注意B尽管说到了change，但immediate是原文没说的;A没说;D说反了，应该是增加
8.注意 句子 中的seem和in fact，seem叫做看上去，也就是事实很可能不是这样，后面的in fact叫做事实上，也就是说前面说的很可能不是事实，两者呼应，都说明两句话之间的关系是转折，所以while正确
9.先看本句，现代人认为希腊的pots上的design只是装饰，没有实际意义，但事实上是有意义的，中国的pots也这样，所以B正确。A错，不是pots decorative，而是design;C说反，D没说方式，所以how错
10.问下面哪个是design的替代意义，倒数第二句整个都在说pots上design的意义，提到了emperor和empress，皇帝和皇后，所以A的Chinese rulers正确，统治者;其他都没说
11.问题中关键词不明显，排除法。A的ordinarycitizens和aristocrat原文没说;B的foreign influence做关键词定位至最后一句的European，说直到引入欧洲theme之后中国原有的装饰的意思才被obscure，对应B，没有foreign influence那些意思不会改变，正确;C没说;D反了，应该是ancient更熟悉
12.these往前找，找主语。注意从句子一开始到exist之前都是句子的主语，但of之前的东西是整个句子的核心，所以答案是description，对于什么什么的描述，描述才是核心，不是types of ware
13.两个过渡点，名词foreign trade和coloring。foreigntrade对应原文第四句的from Middle East Chinese acquired blabla和倒数第二句的tradingactivities，所以B/C/D都有可能;coloring证明B或者C正确。按照正常逻辑，应该先总括，说外贸也使染色技术发生变化，接着再说怎么变的，所以B正确，C错误
14.The Chinese选项对应第二段第二句，正确
The shape选项原文没说，不选
As选项对应原文第四段第一句，正确
Chinese选项原文没说，不选
Before选项对应原文第五段最后一句，正确
Ceramics选项MS对应原文最后一段，但最后一段没说imperial陶瓷是用于both情况的，也不选

【1】尽管中国曾饱受入侵，偶尔丧失主权受制于外国，她仍然拥有世界上最源远流长的文明。像中国一个拥有悠久文明的大国，而陶瓷在其复杂的社会历史以及视觉历史中扮演了极为重要的角色。
【2】在中国，每一个朝代陶瓷的功能和地位都是不同的，所以，根据它们的质量和制作年代的不同，可以是实用器物、陪葬品、贸易 收藏 品，甚至是礼器。对于容器、瓦片等建筑材料、模仿的物体或人物，陶瓷广义上被分为3大类：陶器、炻器和瓷器。另外，瓷器中还有很重要的一类就是宗教用途的雕塑，它们多数是陶质的。
【3】尽管最早的陶瓷是在制陶的温度下烧制的，但是早在公元前15世纪，就已经出现了上釉的高温炻器。六朝时期(公元265-589年)，中国北方就有窑炉在烧制优质的高温瓷器。从7世纪到10世纪，河北以及河南省产的白瓷逐渐演变成为享有盛名的宋瓷(公元960-1279年)——长久以来被认为是中国陶瓷业历史中的巅峰时期之一。宗教雕塑的传统在大部分历史时期中都有延续，但是没有炻器和瓷器质地的雕塑描绘的那么清晰，有一种古老的习俗，就是将刻着新的宗教形象和建筑装饰的陶器作为陪葬品。瓷制品还包括汉朝的铅釉随葬陶俑，唐朝的三彩铅釉器皿和人物，明朝的以泥釉凸纹展现轮廓的三彩寺庙装饰物以及很多用来仿制贵重器皿的陪葬瓷器。
【4】西方国家和繁荣稳定的历代中国朝代之间的贸易促使双方互相引入了新的形式和不同的技术。有一个意义最为深远的例子，公元9世纪精美中国瓷器出口到阿拉伯世界，带来巨大的影响。阿拉伯人对这些瓷器赞不绝口，于是他们鼓励制陶来仿制瓷器，并激励人们研究制作方法。中国人从中东获得了一种蓝色颜料——一种纯化的氧化钴，当时在中国并未出现，其中只含有少量的锰。中国境内发现的钴矿石含有大量的会产生暗蓝灰色的锰元素。17世纪，大量中国装饰类瓷器通过荷兰东印度公司的交易活动流入欧洲，这刺激和影响了广泛多样的瓷器的生产，特别是代尔夫特 。中国人自己改良了很多种来自西方的特殊器皿，比如长嘴的瓶子，并专门为欧洲市场设计了一系列装饰性图案。
【5】就像希腊的陶器上所绘的图案，今天看来也许纯粹是为了装饰，然而事实上在当时它们都是人们精心烧制而成的，它们的意义在当时非常明确，中国的瓷器也是如此。以20世纪的眼光来看，中国制造的陶瓷也许仅仅是装饰品，但是对于中国人来说每个物件的形状及它的装饰都有寓意非凡，影响深远。龙代表皇帝，凤代表皇后;石榴意味着多子，双鱼意味着幸福;鸳鸯寓意着婚姻幸福美满;松树、桃树以及鹤都是长寿的象征;鱼跃出水面意味着科举考试会高中。但是欧洲的装饰主题被引进后，这些寓意就变得不再那么流行甚至丢失了。
【6】陶瓷器皿在很早期就已用于宗教和日常生活中。朝廷分派了制作工作，并于元朝(公元1279-1368年)在景德镇设立了一座官窑。陶瓷器皿在一些宗教仪式上也有着重要的地位。现存的关于不同类型的陶瓷器具很多长篇且抒情的描述可以帮助我们对其进行分类，尽管这些描述有时候会使得一幅大而复杂的画面显得凌乱。
