相信同学们对英语四级阅读的各个题型都很熟悉了吧，但是这只是理论，到了实战，英语四级阅读备考之词汇理解该怎么做呢?这要求考生掌握一些答题技巧，具体的请看下面的解析12月英语四级阅读备考之词汇理解该怎么做。

【解题方法】

一、辨析词性

把十五个选项按词性分别归入名词、动词、形容词、副词等类别。

纵观样题和真题，我们知道15个词汇都属于最重要的四类实词。我们要学会每种词汇的基本搭配和基本用法。

辨性要注意下面几点。

1.遇到动词进行二次分类：确定时态，确定是第三人称单数还是非第三人称单数;但应注意动词+ed型的有两种可能性，动词或形容词;遇到名词要确定单数还是复数。

2.不认识的单词，看后缀。构词法中，前缀表明意思，后缀表明词性。所以看一个词的后缀，往往能大致分出词性。

3.词性一时无法确定的，暂时搁置，不必纠缠，影响全局。

4.作出相应的标记。可直接用自己最清楚的符号清楚标在每个词前后。不清楚的都标问号。
