很多同学在学习英语的过程中认为最难的就是语法，学习四级语法一定要先理解，这样才能真正掌握。下面是小编给大家分享的四级语法知识，大家可以作为学习的参考。 定语名词的复数 名词作定语一般用单数，但也有以下例外。 1) 用复数作定语。 如：sports meeting 运动会 students reading-room 学生阅览室 talks table 谈判桌 the foreign languages department 外语系 2) man, woman, gentleman等作定语时，其单复数以所修饰的名词的单复数而定。 如：men workers　　women teachers

英语四级备考的过程中，语法是学习的重点。学习语法首先要学习句子，因为句子是人类语言的核心，通过对句子的分析理解，可以更好的掌握语法。下面是小编整理的英语四级语法知识，大家可以作为学习的参考。 词作定语一般用单数，但也有以下例外。 1) 用复数作定语。 如：sports meeting 运动会 students reading-room 学生阅览室 talks table 谈判桌 the foreign languages department 外语系 2) man, woman, gentleman等作定语时，其单复数以所修饰的名词的单复数而定。 如：men workers　　women

英语四六级考试是同学们在大学里面最关心的一项考试，对于应届生来说很重要。下面是英语四级语法知识的分享，大家可以作为学习的参考。 1) 用于完成时的区别 延续动词表示经验、经历; 瞬间动词表示行为的结 果，不能与表示段的时间状语连用。 He has completed the work.　　他已完成了那项工作。 (表结果) I've known him since then.　　 我从那时起就认识他了。(表经历) 2)　用于till / until从句的差异 延续动词用于肯定句，表示"做……直到……" 瞬间动词用于否定句，表示"到……，才……" He didn't come back

过去式; 表示将来不可能实现的愿望用“would/could+动词原形”; 表示过去不可能实现的愿望时用“had+过去分词”。如： I wish I were better-looking. 要是我长得再漂亮些就好了。 I wish I had met the film star just now. 我要是刚才遇到那位电影明星该多语四级的过程中，单词的积累和语法的掌握是学习的重中之重。下面是关于虚拟语的知识点，虚拟语好啊! I wish I would be a solider. 我想当一名军人。 虚拟语气在状语从句中的应用 1. if only的条件状语从句中的虚拟语气 if only 与 I wish一样，也用于表示与事实相反的愿望，其后所接虚拟语气的时态与 wish 后所接时态的情况相同。如： If only the player had had more courage! 这位选手再多有一些勇气就好了。 If only Daisy would go with me! 黛茜要是愿意和我一起去就好了! 以上就是小编给大家整理的英语四级语法知识，希望可以给大家在备考的时候带来四级的过程中，单词的积累和语法的掌握是学习的重中之重。下面是关于虚拟语的知识点，虚拟语气主要体现在三个方面：基本用法，各自为政，以及含蓄之美。 虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句;一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如 If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如 If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气. 错综时间条件句 有时条件从句的动作和主句动作发生的时间不一致，这时需要根据意思采用表示不同时间的动词形式来进行调整。 If she had taken the doctor’s advice, she might still be alive. If I were you, I would have accepted their terms. 含蓄条件句 1.有时候假设的情况并不用条件从句表示出来，而是通过介词短语来表示。 如 Without air(If there were no air), there would be no living things. But for your help (If it hadn’t been for your help), I couldn’t have done it. 2. 假设的条件通过上下文表现出来。 I would go abroad for further study but that I am poor. I was ill that day. Otherwise I would have taken part in the party. 虚拟语气在名词性从句中的应用 “wish+宾语从句”表示不可能实现的愿望，汉语可译为“可惜……、悔不该……、但愿……”。表示现在不能实现的愿望，从句的谓语动词用过去式; 表示将来不可能实现的愿望用“would/could+动词原形”; 表示过去不可能实现的愿望时用“had+过去分词”。如： I wish I were better-looking. 要是我长得再漂亮些就好了。 I wish I had met the film star just now. 我要是刚才遇到那位电影明星该多好啊! I wish I would be a solider. 我想当一名军人。 虚拟语气在状语从句中的应用 1. if only的条件状语从句中的虚拟语气 if only 与 I wish一样，也用于表示与事实相反的愿望，其后所接虚拟语气的时态与 wish 后所接时态的情况相同。如： If only the player had had more courage! 这位选手再多有一些勇气就好了。 If only Daisy would go with me! 黛茜要是愿意和我一起去就好了! 以上就是小编给大家整理的英语四级帮助。

句中某一名词时，多用which，如： Beijing, which he was born, is our capital. (9)代替主句中的形容词时, 常用which，如： Lily thought me clever, which she herself was. 在定语从句中，相比于which VS that，who VS that，我们对which与as两者区四级备考的时候，which和as都可以引导非限制性定语别的关注度要少很多，在遣词造句或是口语表达中，也常常是“跟着感觉走”。 以上就是小编给大家分享的英语四级语法知识，希望可以给大家备考带来四级备考的时候，which和as都可以引导非限制性定语从句，有时可以互换使用。但两者的用法又有所不同。下面是小编给大家分享的相关内容，大家可以作为学习的参考。 (1)位置上，as可放在句首、句末，也可插入主句中;which一般放在主句之后(有时也可用as)： As we all know, reading is very important. Reading is very important, which we have already known when we were very young. (2)意义上，as有正如、按照、正像之意，一般用在肯定句中;which可用于含肯、否定意义的句子中： He failed in the exam again, as was expected. He failed in the exam again, which was unexpected. (3)当定语从句所修饰的主句内容是谓语动词的对象时，常用as，如： Jack was admitted into the university, as we had expected. (4)固定结构，用as： as has been said before as often happens as is well known as we all can see the same...as such...as (5)当关系代词代表主句引起的结果，又做主谓宾补(SVOC)结构中的主语时，多用which： He passed the exam, which made him delighted. (6)在从句中作介词宾语时，用which，如： They went to the zoo, after which they saw a film. (7)在从句中代表主句中的谓语的整个概念时，常用which，如： He can write a letter in English, which I cannot. (8)指代主句中某一名词时，多用which，如： Beijing, which he was born, is our capital. (9)代替主句中的形容词时, 常用which，如： Lily thought me clever, which she herself was. 在定语从句中，相比于which VS that，who VS that，我们对which与as两者区别的关注度要少很多，在遣词造句或是口语表达中，也常常是“跟着感觉走”。 以上就是小编给大家分享的英语四级帮助。

语四级听力考试中需要听句子，阅读中需要句子，作文中需要写句子，而语法可用。如： As [When, While] she was waiting for the train, she became very impatient. 她在等火车时，变得很不耐烦。 若是“主长从长”型，即主句和从句为两个同时进行的动作或存在的状态，且强调主句动作或状态延续到从句所指的整个时间，此时通常要用while。如： I always listen to the radio while I'm driving. 我总是一边开车一边听收音机。 但是，若主句和从句所表示的两个同时进行的动作含有“一边……一边”之意时，则习惯上要用as。如： He swung his arms as he walked. 他走路时摆动着手臂。 若是“主长从短”型，即主句是一个持续性动作，而从句是一个短暂性动作，此时可以用as或when，但不能用while。如： It was raining hard when [as] we arrived. 我们到达时正下着大雨。 2. 根据主句
