四级考试语法相关要求。
一、大纲要求
最新《大学英语教学大纲》（1999）对四级语法的要求是：“巩固和加深基本语法知识，提高在语篇水平上运用语法知识的能力。”
二、四级语法结构与词汇考查内容
四级考试对语法词汇的考查与《大纲》要求是十分一致的。综观近年来的四级考试题，我们不难发现四级考试语法词汇部分是这样体现《大纲》的。
1．语法考题的涉及面宽
近年考题曾经考到：几乎所有词类，三种动词的非谓语形式，名词从句，形容词从句，副词从句，独立主格，一致，倒装，强调等基本语法知识。
2．语法考试的重点突出
语法考试的重点为内容庞杂较难掌握的项目，这些项目还反复出现如：虚拟语气，状语从句，定语从句，独立主格，情态动词。
3．具体考查重点为以上项目中的特殊用法，不常用的情况
1）虚拟语气的考点为：would rather＋that从句＋一般过去时：It is vital／ necessary／ important／ urgent／ imperative／ desirable／ advisable／ natural／ essential＋that＋动词原形；It is time／about time／high time＋that＋一般过去时：proposal／suggestion＋that＋动词原形；lest＋that＋should＋动词原形；if only＋that＋would＋动词原形。
2）状语从句的考点为：非if引导的条件状语从句，此类句子多用at times，provided，so long as，in case，once等来替代if；由even if／so，now that，for all等引导的让步状语从句；just／hardly…when引导的时间状语从句；more than，as…as，not so much as，the same as，as much as等引导的比较状语从句。
3）独立主格结构多以逻辑主语＋分词的形式出现。
4）情态动词多与完成时形式连用。
5）定语从句重点考查介词＋关系代词（which）和as作为关系代词。
4．词汇的考查重点为
1）动词，名词与介词的搭配如：popular／patient＋with；yield／solution／adapt／transfer／access＋to；accuse／require＋of；charge＋for；under＋discussion等等。
2）习惯用法如：confess to／set about／be used to＋doing；
be supposed to／have／make sb．＋do等。
3）由同一动词构成的短语如：come，go，set，break等构成的短语。
4）单个的动词，抽象名词，形容词和副词多以近义词、同义词的形式出现。
5）介词短语在句中作状语如：in terms of；with the exception of；in vain等，另外还应注意rather than，other than，such as，none／nothing＋but等词在考题中的出现。
5．近年来考题中的新趋势为：若干考点混合出现：一些交际用语也时常出现在考题中。
