英语四级语法全解
语法是学习一门语言必备的技能，学好语法能更好掌握一门语言，以下是小编给大家带来的英语四级语法全解，欢迎阅读，希望对你有帮助
1. 虚拟语气。
强调说话人的主观愿望和假想情况。考生应着重复习能引起虚拟语气的某些介词、介词短语和连词(如lest, in case, otherwise等);一部分表示建议、主张、命令、紧要等概念的词语，由于本身隐含说话人的`主观愿望，其后的主语从句、宾语从句、同位语从句往往采用“should+动词原形”;虚拟倒装句;在would rather, wish, as if, it’s time that等句型中使用适当形式表达主观愿望;混合虚拟句。
2. 主谓一致。
这类考题灵活性大，需要根据实际情况判断谓语动词的单复数形式。一部分具有生命意义的集合名词做主语时谓语动词多采用复数形式，如people, poultry, militia等;用and连接的成分表单一概念时谓语动词用单数;就近原则：主语中含有某些连词(如as well as, besides, in addition to等)时，谓语动词的数同第一个主语保持一致。
3. 倒装结构。
表示强调或突出，分为全部倒装和部分倒装。那些否定词(组)、介词短语能引起倒装句，部分倒装和全部倒装有和区别，as在倒装结构中的用法及意义等等，都是考生应当重视的地方。
4. 非谓语动词。
这是词汇与结构考试中语法部分的重中之重，解题时可以从三个方面入手：
①根据非谓语动词同其所修饰的名词或逻辑主语的一致关系，确定使用主动语态或被动语态，然后考虑采用现在分词、现在分词被动式或过去分词;
②非谓语动词同主句谓语动词动作发生的先后关系。动作正在进行的用现在分词进行式，同时发生或不分先后发生的用现在现在分词一般式或过去分词;在主句谓语动词之前发生的用现在分词完成式、不定式完成式;发生在主句谓语动词之后的多用不定式一般式;
③表状态多用分词，表目的多用不定式。
5. 独立主格题。
一般说来，在句子中没有连接词的情况下，逗号是无力连接两个句子的，其中一个分句要么是非谓语形式，要么是独立主格结构。这两种结构都做状语，不同的是独立主格结构有自己的逻辑主语。
6. 时态。
英语中一共有16个时态，最常用的5个时态是一般现在时、现在进行时、一般过去式、一般将来时和现在完成时。四级考试中出现最多的考点是将来完成时、现在完成时、过去完成时和完成进行时。针对这一题型，考生首先要抓住的就是时间状语，是现在时间、将来时间还是过去时间?是短暂时间还是延续性时间?
7. 名词性从句。
形容词性的定语从句是考核的重点，用什么引导词，引导词前面的介词形式，引导词在从句中做什么成分(做宾语、主语还是状语等)，从句的语序等等均有可能成为考点。此外，主语从句、同位语从句、宾语从句也应适当复习。
