2021大学英语四级语法考点复习汇总(重点)
1.英语四级语法考点复习:ago与before
ago与before的用法区别
1)两者均可表示在多久时间“以前”(要放在表示一段时间的词语之后),但有区别:ago从现在向前回溯,即现在的过去,因此通常与一般过去时连用;而 before则从过去向前回溯,即指过去的过去,因此通常与过去完成时连用(尤其用于宾语从句中)。如:
I bought the computer two years ago. 我是两年前买这台电脑的。
He said they had left five days before. 他说他们 5 天前就离开了。
注:在表示推测或为使语境生动的句子中,有时也可用ago代替before.如:
He must have left a week ago. 想必他在一星期前就离开了。
I had thought that he had died at least 20 years ago. 我原以为他至少在 20 年前就已经去世了。
(2)before 有时单独使用(即不连用具体时间),泛指一般意义的“以前”,此时可用于一般过去时,也可用于现在完成时。如:
He didn‘t know that before. 他以前不知道此事。
I have been there before. 我以前去过那儿。

有的与形容词同形的副词与以-ly结尾的副词意义差别不是很大。我们可从以下几个方面来区分:

3.在take it easy(别着急),go easy(从容不迫),easier said than done(说来容易做来难),easy come,easy go(易得则易失)等中不用easily.

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。
