同六分词汇标准相比，7分多了两个要求：flexibility(灵活性)andprecision(准确性)。灵活性暗示我们在作文中要设置同意替换词[1]。比如，第一段写了developingcountries,第二段就可以用thesenations,第三段可以用poorregions
准确性指在该题目下贴切的，核心的词汇[2]。比如政府话题写出welffare福利一词，环保话题写出environmental-friendly一词。
7分和6分同时要求：要有lesscommonlexicalitems,不普通的，含义较深刻的词汇。比如undermine(v.逐渐破坏)代替damage;用dilemma代替problem。用的好不好，地道不地道，是否注意到了style(文体)和collocation(搭配)决定了是6还是7.
所以在写作中，词汇在准确使用的基础上，我们一定要注意设置同意替换词。在练习时我们就要不断积累同意替换词，在经常使用的单词上多想想，还可以替换什么样的词和表达方式。

(那么什么算是avarietyof呢?3种以上才称得上avarietyof,所以写作中要写出4种以上不同的从句。剑桥书后的考官范文，平均每篇12句话，2句话是简单句，2句话是并列句，其余8句都是各种从句)

英文句式：简单句，并列句，限制性定语从句=分词做定语，非限制性定语从句，名词性从句(主语从句，宾语从句，表语从句，同位语从句)，状语从句=分词做状语，强调句，倒装句，插入语结构，双重否定表肯定结构
在写作中，我们要熟练，正确，恰当的应用多种句式与结构。当然除了句式我们还有时态，准确恰当运用各种时态在简单句和复合句中。
