大学英语必考语法考点
导语：大学英语的语法比高中时代学得更深入了，考点也有所改变，下面是我收集整理的大学英语必考语法考点，欢迎参考!
1.as...as...引导的比较级：
(1)“as +形容词或副词原级+ as+被比较对象”结构。例句： He studies as hard as you. 他像你一样学习努力。
(2)在否定句或疑问句中可用 not so…as…. 例句：He can not run so/as fast as you. 他没你跑得快。
2.only引导的倒装句型：only +状语 (或状语从句)位于句首时，句子部分倒装。
例句： Only by diligence and honesty can one succeed in life. 只有勤奋、正直，一个人在生活中才能成功。
注意：但 only修饰主语时，不倒装。例句： Only that girl knew how to work out the problem. 只有那位女生知道怎样解那道题。
3.wish引导的虚拟语气：wish 后面的从句，当表示与事实相反的情况，或表示将来不太可能实现的愿望时，其宾语从句的动词形式为：
(1)表示对现在情况的虚拟：从句动词用过去式或过去进行式表示，be 的过去式用were.
I wish I knew the answer to the question. 我希望知道这个问题的答案。(可惜不知道。)
(2)表示对过去情况的虚拟：从句动词用had +过去分词。
I wish (that) I hadn’t wasted so much time. 我后悔不该浪费这么多时间。( 实际上已经浪费掉了。)
(3)表示对将来的主观愿望：谓语动词形式为“would/ should/ could/ might +动词原形”。在这种情况下，主句的主语与从句的'主语不能相同，因为主句的主语所期望的从句动作能否实现，取决于从句主语的态度或意愿(非动作名词除外) 。
I wish it would stop raining. 但愿雨能停止。
注意：若wish 后的宾语从句中用 would，可以表示请求，通常意味着说话人的不快或不满。
例句：I wish you would be quiet. 我希望你安静一些。
4.it形式宾语：和it 作形式主语一样， 我们常用it 来作形式宾语， 把真正的宾语从句放在句末， 这种情况尤其出现在带复合宾语的句子中。
例句：He has made it clear that he will not give in. 他表明他不会屈服。
5.The+比较级，the+比较级 表示“越.....越......"
例句：The more scared we are, the stronger the difficulty will become。我们越害怕困难，困难就会变得越强大。
6.as引导的非限制性定语从句
在as引导的非限制性定语从句中，连接代词as在句子中可以作主语、宾语或表语等，可以指人或物。其在定语从句中的位置比较灵活，即可以在句子 前面，在句子中间或句子末尾。常用的结构有：as we all know; as is well known to…; as is often the case; as is said/mentioned above; as has been said before; as I told you before; as is evident; as often happens; as can be seen; as is/was expected; as we expect; as I can remember等。
7.which引导的非限制性定语从句
which引导的非限制性定语从句既可以指整个句子内容，也可以指句子的部分内容(如单词或词组等)，在句子中可以作主语、宾语(动词或介词 的)、定语等。注意它在句子中的位置：只能放在主句后，不能放在主句前。表达的内容是"不好的"、"事先没有预料到的"等时，常用which，只指物。
as, though, although引导的让步状语从句。
[注意]although位于句首;though位于句首或句中;as位于句中=though。它的词序是把句中强调的形容词、副词、动词或名词放在连词前。
;大学英语语法知识点归纳思维导图
大学英语语法知识点归纳如下：
1、it形式宾语：和it 作形式主语一样，常用it来作形式宾语，把真正的宾语从句放在句末，这种情况尤其出现在带复合宾语的句子中。
2、such位于句首时，主谓完全倒装。
3、as起连接作用，表达说话人的观点、看法，并指出主句内容的根据或出处，意为“正如，正像”。
4、宾语从句：放在介词后面，作介词的宾语。
5、比较those who和anyone who，前者是“那些……的人”，后者表示“任何……的人”。区别就是在于those who是一个复数的概念，“那些人”，后面的谓语动词要用复数；而anyone who是表示任何一个人，后面要用单数的谓语动词。
大学英语四级语法考点总结大全
一、英语四级语法考点的学习方法
语法知识的学习，大家可以不用买语法书。在真题中学习语法知识是很不错的。很多人可能会说，在真题中学习语法知识，现在很多真题都只有长难句的解析，对于简单句都没有讲解，自己基础很差，完全看不懂，必须要买语法书。
二、英语四级语法考点知识整理
①虚拟语气：强调说话人的主观愿望和假想情况。大家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。
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，部分倒装和和全部倒装有区别，as在倒装结构中的用法及意义等等，都是大家应当重视的地方。
④ 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。
⑤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。
