对于考研英语差的同学，一定要先做好英语复习规划，把功夫下早，把阅读基础打夯实，新题型也是很重要的题型，需要掌握一些技巧和词汇，小编整理"2021考研英语阅读新题型：熟词生义(三)"，希望可以帮助到大家！
[E] These issues all have root causes in human behavior . all require behavioral change and social innovations ,as well as technological development . Stemming climate change ,for example ,is as much about changing consumption patterns and promoting tax acceptance as it is about developing clean energy.(2013，英语一)
Stem 一词常见意思为起源于，常见用法为stem from 起源于，相当于熟知的originate from，然而，stem在本文中，熟词生义为阻止，遏止，更符合上下文语境，上文提到人类行为是造成各种问题的根本原因，下文提到解决气候变化问题，应当采取的措施。所以，本句句意为遏止气候变化，例如，可以采取以下措施，一、改变消耗模式;二、促进税收接受度;三、研发清洁能源。
The researchers suggest that capuchin monkeys,like humans,are guided by social emotions. In the wild,they are a co-operative,group-living species. Such co-operation is likely to be stable only when each animal feels it is not being cheated. Feelings of righteous indignation,it seems,are not the preserve of people alone. Refusing a lesser reward completely makes these feelings abundantly clear to other members of the group. However,whether such a sense of fairness evolved independently in capuchins and humans,or whether it stems from the common ancestor that the species had 35 million years ago,is,as yet,an unanswered question.(2005,Text 1)
Stem一词早在2005年考研英语一的阅读理解中就已经考察过，stem 在文中的意思为起源，与from 构成固定搭配，句意为然而，是否这种公平感分别源于僧帽猴还是人类，或是是否源于3500万年前共同的祖先，还不得而知。
28.Hindrance to the reform of the legal system originates from
[A]lawyers’ and clients’ strong resistance.
[B]the rigid bodies governing the profession.
[C]the stem exam for would-be lawyers.
[D]non-professionals’ sharp criticism. (2014，英语一，Text 2)
Stem 在2014年，英语一阅读理解28题的选项中，再次出现，这次，针对stem考查的释义是干，主干，stem 与exam 连用，意为主要测试，体现了stem为主干的这层释义。
至今，考研英语考研试题对stem 阻止，遏止;起源于;干，主干，三层释义都已考察过。因此，考生在备考阶段，要尽可能将考研试题中考查的词汇多层释义都进行记忆。最后，中公伴你一路同行，愿风雨同舟，一路向前。抵达彼岸，等待花开。
