英语四级语法用法辨析：keen on doing sth 与keen to do sth 的区别

但有时也表示“渴望做某事”，如《朗文多功能分类词典》中就有这样一句：
I’m keen on passing this examination. 我渴望通过这次考试。
2)keen to do sth 主要表示“很想做某事”“渴望做某事”。如：

英语四级语法用法辨析：until 后接过去分词
请看这道题，这个until 后要接过去分词吗?
He is a man of few words, and seldom speaks until _________ to.
A. spoken B. speaking C. speak D. be spoken
【分析】此题容易误B，认为until 是介词，后接动词时用动名词形式。其实，此题应选A，until spoken to 为 until he is spoken to 之省略。句意为“他是个沉默寡言的人，别人不同他说话，他很少同别人说话”。按英语习惯，一些表示时间、地点、条件、方式、 让步慧春等的状语从句，若其主语与主句主语一致，且从句谓语包含动词be, 那么可将从句的主语和动词be省略：
You must study hard while (you are) young, or you will regret when (you are) old. 趁年轻时要努力学习，不然到老了你会后悔的。
I won't go unless (I am) invited. 我不会去, 除非请我。
Look out for cars when (you are) crossing the streets. 过马路时要注意汽车。
While (I was) waiting I was reading some old magazines. 等的时候我在看一些旧杂志。
He worked very hard though (he was) still rather poor in health. 尽管身体还不好，但他仍努力工作。
He will work hard wherever (he is) sent by the Party. 无论党把他派往哪里,他都会努力工作。
请再看两道试题：
(1) If carefully _________, the experiment will be successful.
A. do B. does C. done D. doing
答案选C，可视为 if it is carefully done 之省略。
(2) The research is so designed that once _________ nothing can be done to change it.
A. begins B. having begun C. beginning D. begun
答案选D，可视为 once it is begun 之省略。
【篇三】2020年12月英语四级语法用法讲解
英语四级语法用法辨析：介词below与under的用法区别
1. 两者都可表示“低于”，under 主要表示垂直在下的正下方，而 below 则不一定表示正下方(即可以是正下方或非正下方)。如：
Look in the cupboard below [under] the sink. 到洗碗池下面的柜子里找一找。
The climbers stopped 300 meters below the top of the mountain. 登山队员们在离山顶 300 米处停了下来。
换句话说，表示正下方，两者都可用;不表示正下方，则通常用below。
2. 两者均可表示数量方面的“少于”，但在现代英语中，以用 under 为多见。如：
He can't be much below [under] sixty. 他的年龄不可能比 60 岁小很多。
There were under forty people at the meeting. 参加会议的人不足 40 人。
It took us under an hour. 我们用了不到 1 个小时。
注：在现代英语中，below 表示“少于”，主要用于表示温度、高度以及有纵向标准可比的情况。如：
This place is below sea level. 此地在海平面以下。
The temperature is two degrees below zero. 温度是零下 2 度。
3. 若表示一物被另一物所覆盖，则通常用 under。如：
She crept in beside him under the bedclothes. 她钻进被窝躺在他身旁。
4. 表示职位、级别等关系时，用 under 表直接关系，用 below 表非直接关系。比较：
Mr A is under Mr B. A 先生是 B 先生的部下。
Mr A is below Mr B. A 先生比 B 先生职位低。

什么是助动词
1)协助主要动词构成谓语动词词组的词叫助动词(Auxiliary Verb)。被协助的动词称作主要动词(Main Verb)。
助动词自身没有词义，不可单独使用，例拿缺伏如：
He doesn't like English.他不喜欢英语。
(doesn't是助动词，无词义;like是主要动词，有词义)
2) 助动词协助主要动词完成以下功用，可以用来：
a. 表示时态，例如：
He is singing.他在唱歌。
He has got married.他已结婚。
b. 表示语态，例如：
He was sent to England.他被派往英国。
c. 构成疑问句，例如：
Do you like college life?你喜欢大学生活吗?
Did you study English before you came here? 你来这儿之前学过英语吗?
d. 与否定副词not合用，构成否定句，例如：
I don't like him. 我不喜欢他。
e. 加强语气，例如：

和more有关的词组
1) the more… the more…越……就越……
The harder you work，the greater progress you'll make.
2) more B than A与其说A不如说B
less A than B
He is more lazy than slow at his work.
= He is less slow than lazy at his work.
3) no more… than… 与……一样……，不比……多
The officials could see no more than the Emperor.
no less… than…与……一样……
扮辩He is no less diligent than you.
4) more than不只是，非常
She is more than kind to us all.
典型例题
1)The weather in China is different from____.
A. in America B. one in America C. America
D. that in America
答案：D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家，C不能选。A没有名词，后句成分不全，排除。B和D中，B中的one常用来代替可数名词，而that可车以代替不可数或抽象名词，所以选D。
2)After the new technique was introced，the factory proced ___ tractors in 1988 as the year before.
A. as twice manyB. as many twiceC. twice as manyD. twice many as
答案C. 此句意为"这个厂1988能生产的拖拉机是往年的两倍"。 表示倍数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为C。

Ⅵ 定语从句
限制和非限制性定语从句: 限制性定语从句是名词词组不可缺少的一个组成部分, 去掉了会造成病句或意义不明确; 非限制性定语从句属于补充说明性质, 去掉了不会影响主要意义, 通常用逗号与它的先行词分开.
The boys who wanted to play football were disappointed when it rained.
The boys, who wanted to play football, were disappointed when it rained.
如果定语从句的先行词是专有名词, 或是带有形容词性物主代词(my, his, etc)或形容词性指示代词(this, that, etc)作限定词, 其后的定语从句通常都是非限制性的:
Mary Smith, who is in the corner, wants to meet you.
Her mother, who had long suffered form arthritis, died last night.
All these books, which have been donated by visiting professors, are to be used by the postgraates.
在非限制性定语从句中只能用who/whom指人, 用which指物,通常不用that替代.
My father, who had been on a visit to America, returned yesterday.
All the books, which had pictures in them, were sent to the little girl.
定语从句的引导词
that, who, whom: 非限制性定语从句, 如果修饰人, 一般用who, 有时用that (作主语时用who较多). 如果关系代词在从句中作宾语, 就应当用宾格 whom 或that, 但在大多数情况下都可以省略掉, 在口语中可用who代替whom.
Here is the man (whom) you've been looking for.
He is a man (that) you can safely depend on.
The people (who/that) you were talking to were Swedes.
There are some people here who I want you to meet.
但在介词后只能用whom:
This is the man to whom I referred.
但在口语中一般都把介词放到句子后面去, 这时可用that, 但省略时更多一些.
Have you met the person about whom he was speaking?
Have you met the person (that) he was speaking about
The girl to whom I spoke is my cousin.
The girl (who/that) I spoke to is my cousin.
限制性定语从句如果修饰“物”, 用关系代词that的时候较多, 也有时用which.. 当这个代词在从句中是用作宾语时, 在绝大多数情况下都是省略的, 特别是口语中(尤其是当被修饰的词是all, everything等词时):
Have you everything you need?
(Is there) anything I can do for you?
All you have to do is to press the button.

短语部分没有独立主语，则短语结构称为非谓语动词。
非谓语动词的结构：分词(分词短语)
句子的主语决定非谓语动词中的分词是用主动还是被动形式。如果是句子的主语发出动作，则使用现在分词;如果动作不是由句子的主语发出，则使用过去分词。
1.No matter how frequently _A_， the works of Beethoven always attract large audiences.
A performed B performing C to be performed D being performed
perform vt. 表演，演出，演奏;
to be performed 将要被演奏; being performed 正在被演奏;
一些特殊的动词：
第一点：forget 忘记; [反义] remember 记得;
这两个词后加动词不定式表示将要进行的行为;这两个词后加动词ing形式表示已经做过的事情。
注意：动名词与现在分词形式一样，但含义不同。这两个词后加动词ing形式都是动名词。
forget to do sth. 忘记要去做某事; forget doing sth. 忘记做过某事;
remember to do sth. 记得要去做某事; remember doing sth. 记得做过某事;
2. I remember _B_ to help us if we ever got into trouble.

动名词的复合结构：凡是一个动词的后面可以加动名词，就可以加动名词的复合结构。
动作发出者 + 动名词;当动作发出者名字给出时：名词所有格 + 动名词;当动名词的复合结构在文章中出现，且动作发出者在前文中提过时：形容词物主代词(宾格)+ 动名词。
形容词物主代词：his， her， my， your， their， our。代词宾格：him， her， me， you， us， them。

非谓语动词与独立主格：短语，句子(或者句子，短语)
当短语部分有独立主语，并且该主语不同于句子主语，这时短语结构称为独立主格。(它最明显的特点是短语部分有独立的主语)。
独立主格的结构1：名词(代词)+ 分词 [现在分词、过去分词]
现在分词表示主动的，正在进行的行为;过去分词表示被动的，已经完成的行为。 作题时要通过判断动作与名词(代词)之间的关系来确定是使用现在分词还是过去分词。当动作由名词(代词)发出时使用现在分词，而名词(代词)是受动者时则用过去分词。
1. Silver is the best conctor of electricity， copper _B_ it closely.
A followed B following C to follow D being followed
2. All things _A_， the planned trip will have to be called off.
A considered B be considered C considering D having considered
call off 取消; cancel vt. 取消; 四级中的考点就是现在分词和过去分词的区别。
独立主格的结构2：with + 名词(代词)+ 分词 [句子当中作状语]
3. After the Arab states won independence， great emphasis was laid on expanding ecation， with girls as well as boys _C_ to go to school.
A to be encouraged B been encouraged C being encouraged D be encouraged
as well as 和(相当于and); be encouraged不会考。
动词不定式有预示将来行为的含义。to be encouraged 将要被鼓励;
been encouraged 已经被鼓励完了，与主句的谓语动词相对;being encouraged 正在被鼓励
短语部分没有独立主语，则短语结构称为非谓语动词。
非谓语动词的结构：分词(分词短语)
句子的主语决定非谓语动词中的分词是用主动还是被动形式。如果是句子的主语发出动作，则使用现在分词;如果动作不是由句子的主语发出，则使用过去分词。
1.No matter how frequently _A_， the works of Beethoven always attract large audiences.
A performed B performing C to be performed D being performed
perform vt. 表演，演出，演奏;
to be performed 将要被演奏; being performed 正在被演奏;
一些特殊的动词：
第一点：forget 忘记; [反义] remember 记得;
这两个词后加动词不定式表示将要进行的行为;这两个词后加动词ing形式表示已经做过的事情。

英语四级语法之名词用法
导语：下面是我整理的关于英语四级考试中常用的一些名词语法，大家认真则仿弯看看，我觉得非常有用。
第一类 形式为单数，但意义可以用为单数或复数
这类集合名词包括family(家庭)，team(队)，class(班)，audience(听众)等，其用法特点为：若视为整
体，表示单数意义;若考虑其个体成员，表示复数意义。比较并体会：
His family is large. 他的家是个大家庭。
His family are all waiting for him. 他的一家人都在等他。
This class consists of 45 pupils. 这个班由45个学生组成。
This class are reading English now. 这个班的学生在读英语。
第二类 形式为单数，但意义永远为复数
这类集合名词包括cattle(牛，牲畜)，people(人)，police(警察)等，其用法特点为：只有单数形式,
但却表示复数意义，用作主语时谓语用复数;不与 a(n) 连用，但可与the连用(表示总括意义和特指)。
如：
People will laugh at you. 人们会笑你的。
The police are looking for him. 警察在找他。
Many cattle were killed for this. 就因为这个原因宰了不少牲畜。
注：表示牲畜的头数，用单位词 head(单复数同形)。如：
five head of cattle 5头牛，fifty (head of ) cattle 50头牛
第三类 形式为复数，意义也为复数
这类集合名词包括goods(货物), clothes(衣服)等，其用法特点是：只有复数形式(当然也表示复数意义
，用作主语时谓语也用复数)，但通常不与数词连用。如：
Clothes dry slowly in the rainy season. 衣服在雨季不易干。
Such clothes are very expensive. 那样的衣服很贵。
If goods are not well made you should complain to the manufacturer. 如果货物质量不好，则理
应向制造商提出控诉。
第四类 形式为单数，意义也为单数
这类集合名词包括baggage / luggage(行李), clothing(衣服), furniture(家具), machinery(机器),
poetry(诗), scenery(风景), jewelry(珠宝), equipment(设备)等, 其用法特点为：是不可数名大神词，只
用单数形式，不用不定冠词(当然更不能用数词)，没有复数形式。如：
Our clothing protects us from [against] the cold. 我们的衣服可以御寒。
Have you checked all your baggage? 你所有的行李都托运了吗?
The thief stole all her jewelry. 小偷把她所有的首饰都偷走了。
The hospital has no decent equipment. 这家医院没有像样的设备。
The Tang Dynasty is thought of as the high summer of Chinese poetry. 人孙闷们认为唐朝是中国诗歌

。如：
a poem / a piece of poetry 一首诗
many machines / much machinery / many pieces of machinery 许多机器
第五类 补充几个常考的.集合名词
除上面提到的四类集合名词外，以下几个集合名词也应重点注意(因为它们也是常考考点)：
1. hair(头发，毛发)：指全部头发或毛发时，为集合名词(不可数);指几根头发或毛发时，为个体名词
(可数)。如：
My hair has grown very long. 我的头发已长得很长了。
The police found two hairs there. 警察在那儿找到了两根头发。
2. mankind(人类)：是一个不可数的集合名词，不用复数形式，也不连用冠词。如：

Mankind has its own problems. 人类有自己的问题。
注：mankind 表示“人(类)”时，虽不可数，但有时却可以表示复数意义，尤其是当其表语是复数时。
如：

3. fruit(水果)：作为集合名词，它通常是不可数的。如：
He doesn’t eat much fruit. 他不大吃水果。
He is growing fruit in the country. 他在乡下种水果。
但是，当要表示种类时，它可视为可数名词，即a fruit 指一种水果，fruits 指多种水果。比较：
Some fruits have thick skins. 有些水果皮很厚。
The potato is a vegetable, not a fruit. 土豆是一种蔬菜，而不是一种水果。

get to do与get doing三大区别
get to do和get doing是两个搭配非常有用的搭配，但许多人并不知道它们之间的区别，更不用说如何准确地使用它们了。现就这两词作一用法归纳，供大学参考。
用法区别一
两者均可表示“开始做某事”，其细微区别如下。
1. get to do往往暗示一个较长的过程，含有“渐渐开始”之意，此时get后接的不定式通常为to know, to like, to hate, to understand, to realize 等表示心理感觉的动词。如：
I really wanted to get to know America. 我真想逐渐了解美国。
I shall get to like them in time. 经过一段时间我会变得喜欢他们的。
The best way to get to know the city is to visit it on foot. 要想了解这座城市，的方法是步行游览。
After a time you get to realize that these things don't matter. 你胡镇隐过些时候就知道这些事无关紧要。
注：有时也可接表示心理感觉之外的其他动词。如：
His drinking is getting to be a problem. 他酗酒越来越成问题了。
旅派He is getting to be a lovely kid. 他慢慢变成一个可爱的孩子了。
You'll get to speak English more easily as time goes by. 时间一长，你的英语就会说得流利一些。
2. get doing主要用于非正式文体中，通常表示某种特定动作的开始，尤其用于get moving, get going, get thinking等搭配中。如：
We'd better get moving—it's late. 我们还是走吧——时间不早了。
They soon got talking together. 他们不久就开始谈了起来。
He got to thinking that she perhaps wouldn't come after all. 他已意识到也许她根本不来了裤厅。
用法区别二
get to do可以表示有机会做某事或被许可做某事，但get doing没有这样的用法。如：
He never got to go to college. 他从无机会上大学。
We didn't get to see her—she was too busy. 我们没有见到她——她太忙了。
When do I get to see your new baby? 我什么时候能去看看你那刚出生的孩子呀?
Did you get to visit the Louvre when you were in Paris? 你在巴黎的时候有机会去参观卢浮宫吗?
用法区别三
get to do还可以表示努力或设法做成某事，但get doing没有这样的用法。如：
At last he got to knock it down. 最后他设法把它敲了下来。
Did you get to buy the tickets? 你设法买到票了吗?
How did you get to be captain? 你是怎样当上船长的?
【篇二】2020年12月英语四级语法用法说明
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。
【篇三】2020年12月英语四级语法用法说明
healthy与healthful用法辨析
1. healthy 有两个意思，一是指“人本身健康的”，二是指“有益于健康的”。如：
Good food keeps you healthy. 好的饮食使你健康。
Cycling is certainly healthier than driving. 骑车肯定比开车有利于健康。
有时用于比喻义。如：
That book is not healthy reading for children. 那本书供小孩读不健康。
2. healthful通常只表示“有益于健康的”。如：
Doing morning exercises is very healthful. 做早操对健康很有益。
Why don't you eat such healthy [healthful] foods? 你为什么不吃那些有益于健康的食物?
此词在现代英语中用得不多(已属过时用法)，一般用healthy代替。
