1、2020年12月大学英语四级语法考点【篇一】2020年12月大学英语四级语法考点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，所以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，所以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

2、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 didnt know that before. 他以前不知道此事。I have been there before. 我以前去过那儿。【篇二】2020年12月大学英语四级语法考点much可修饰哪些词语

3、一、much修饰比较级修饰比较是副词much的常见用法，“much + 比较级”的意思是“更”“得多”。如：Its much colder today than it was yesterday. 今天比昨天冷得多。It was much worse than I thought. 它比我想像的还要糟得多。We will be a much better football team next year. 明年我们将会成为一支更好的足球队。二、much修饰级much修饰级应置于级前的定冠词之前，而不是之后。“much + the + 级”的意思是“最最”“绝对是最”。如：This is much

4、 the most difficult. 这是最最难的。Thats much the best plan. 那绝对是的计划。Of the three boys Nick is much the cleverest. 这三个男孩中，尼克最最聪明。三、much修饰形容词的原级much修饰形容词原级的情形主要见于那些由过去分词转化来的形容词。如：I was much annoyed. 我很不高兴。She wasnt much surprised. 她并不太惊讶。注：有个别非分词转化来的形容词有时也可用much修饰，但这种用法很有限，通常只见于good，different等少数几个形容词。如：I do

5、nt think this battery is much good. 我并不认为这种电池非常好。The new school isnt much different from the old one. 新学校与老学校区别不太大。四、much修饰副词toomuch too 为习语，其中的much修饰副词too;much too可视为too的增强说法，其语气比单独用too更强。如：He spoke much too fast. 他说话说得太快了。This is much too heavy for you to lift. 这东西太重，你拿不起来。注意：much too与too much词序不同

6、，用法也不同。从句法功能上看，much too的用法与too相同，但比too的语气更强;而too much在用法上则与much相同，但比much 语气更强。比较：He drives much too fast. 他开车开得太快了。The shoes are much too small for me. 这鞋子我穿太小了。There is too much rain. 雨水太多了。You have given me too much. 你已经给我太多了。五、much修饰介词短语much主要用于修饰由like，in，to等少数介词所构成的介词短语。如：The baby doesnt look mu

7、ch like you. 这婴儿长得不大像你。Theyre very much in love with each other. 他们彼此在热恋中。Much to my surprise, she did it by herself. 让我极为惊讶的是，这竟然是她自己做的。六、much修饰动词much修饰动词时，通常只用于否定句或疑问句中，一般不能用于肯定句中(除非前面有very，too，so等之类的修饰语)。如：正：She doesnt like him much. (用于否定句，故准确)正：She doesnt much like him. (用于否定句，故准确)正：Does she li

8、ke him much?(用于疑问句，故准确)正：Does she much like him? (用于疑问句，故准确)正：She likes him very too, so much. (其前有修饰语，故准确)注意以下误句：误：She likes him much. / She much likes him. (因为它用于肯定句，且其前没有修饰语，故不准确)但是，不带修饰语的much有时也能在肯定句中修饰动词，但这通常只限于 admire，affect，appreciate，dislike，enjoy，look forward to，prefer，regret等少数动词，且much通常只能

9、放在句中，不放在句末。如：We much appreciate your invitation. 我们非常感激你的邀请。We would much prefer to be given money. 我们还是更喜欢有人给我们钱。These factors have much affected the building of nuclear plants. 这些因素极大地影响了核电站的建立。七、much修饰asmuch as 可视为习语，其意为“虽然”，用法与though相似。如：Much as Id like to help, there isnt a lot I can do. 即使我愿意帮

10、忙，却没有很多事我能做。Much as he admired her looks and her manners, he had no wish to marry her. 虽说他很欣赏她的外貌和仪态，他却无心和她结婚。八、much修饰the samemuch 修饰the same，从表面上是增强了the same的语气，但实际上是缓和了其语气，其意为“情况大致相同”“几乎差不多”“没什么变化”。如：The patient is much the same this morning. 今天早上病人情况几乎没什么变化。Whichever method you use, the result is

11、 much the same. 不论你用哪一种方法，结果都差不多。They eat much the same thing for breakfast every day. 他们每天吃的早餐几乎都一样。【篇三】2020年12月大学英语四级语法考点deep与deeply副词的区别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：位置不同：在动词之前或句首通常只用ly副词。如：He slowly drove the car into the garage.他把车慢慢地开进车库。Quickly everybody stood up.大家很快地站起来。但在动词后，

12、两种副词都可用。如：He drives slow/slowly.他的车开得很慢。He sold it cheap/cheaply.他将它便宜卖了。含义不同：与形容词同形的副词通常指具体情况，而-ly副词多指抽象概念。请比较：He is sitting close to me.他就坐在我边上。Watch closely what I do.仔细瞧我怎么做的。I went deep into the woods.我深入到树林中。Her story moved me deeply.她的故事使我深受感动。The plane was flying high.这架飞机飞得很高。He think highly of your work.他对你的工作评价很高。He opened the door wide. 他把门开得大大的。English is widely used in the world.英语在世界范围内广泛使用。习惯搭配不同：如：1.在stand firm(站稳)和hold firm(固守)中不用firmly.2.在fair and square(正大光明
