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)

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。

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.

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。
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.
A once offering B him once offering C him to offer D to offer him
offer vt. 提出，提供; offer sb. sth. / offer to do sth.
him once offering 如果改成 his once offering 也正确。

too…to 结构通常表示否定意义:
She was too young to understand all that.
enough…to结构则表示肯定意义:
She was not old enough to understand all that.
not too, but too, all too, only too等和不定式连用时,不定式一般不表示否定意义:
He's only too pleased to help her.
so…as (to)这种结构也可用不定式作状语:
Be so kind as to drop in some time when you are free.
如果要说明不定式表示的动作是谁做的, 可以在不定式前加一个for引起的短语:
It is not hard for one to do a bit of good.
It is a great honour for us to be present at this rally.
在以某些形容词(如 kind, good, nice, wise, unwise, clever, silly, wrong, right, foolish, stupid, careless, considerate, rude, naughty, impolite等)作表语时, 不定式前可加一个of引起的短语, 来说明不定式指的是谁的情况:
It's kind of you to think so much of us.
(It is) Awfully good of you to come and meet us.
It's very nice of you to be so considerate.
It's unwise of them to turn down the proposal.
V+ing形式(现在分词及动名词)
形式
完成式: 如果要表示动名词代表的动作在谓语所表示的动作之前发生, 通常用动名词的完成形式.
He didn't mention having met me.
I regret not having taken her advice.
在某些动词后(或成语中), 常用(或可以用)动名词的一般形式, 尽管动作是在谓语所表示的动作之前发生的.
Excuse me for coming late.
I don't remember ever seeing him anywhere.
现在分词的完成式主要用在状语中, 表示这动作在谓语所表示的动作之前发生.
Having been there many times, he offered to be our guide.
Having found the cause, they were able to propose a remedy.
另外, 独立结构也可用现在分词的完成形式.
The guests having left, they resumed their discussion.
The children, having eating their fill, were allowed to leave the table.
被动式: 当一个动名词逻辑上的主语所表示的是这动作的对象时, 动名词一般要用被动形式.
His being neglected by the host added to his uneasiness.
He couldn't bear being made fun of like that.
但要注意, 在want, need, deserve, require 等动词后, 尽管表示的是被动的意思, 却用动名词的主动形式.
My pen needs filling.
The point deserves mentioning.
This problem requires studying with great care.
在worth这个形容词后情形也是这样.
Her method is worth trying.

;④ 大学英语四级对语法的要求
大学英语四级的语法主要有虚拟语气，主谓一致，独立主格，名词性从句以及时态等等，四六级是不直接考察语法，但是听力中需要听句子，阅读中需要句子，作文中需要写句子，而语法是句子的骨架，有句子的地方就有语法，所以语法基础是四六级做题之根本。
虚拟语气：强调说话人的主观愿望和假想情况。考生应着重复习能引起虚拟语气的某些介词、介词短语和连词；主语从句、宾语从句、同位语从句，虚拟倒装句等等。
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。
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，部分倒装和全部倒装有何区别。
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。
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(作宾语、主语还是状语等)，从句的语序等等均有可能成为考点。

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：

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。

⑥ 2021年上半年英语四级语法用法详解
【 #四六级考试# 导语】梦想在前方，努力在路上。对于考生来说，拿到证书就是我们向往的远方。以下是“2021年上半年英语四级语法用法详解”，欢迎阅读参考！更多相关讯息请关注 ！【篇一】2021年上半年英语四级语法用法返缓尘详解
1. come 和 go 是一对反义词，come(来)所表示的方向是朝向说话者的位置，而go(去)所表示的方向是离开说话者的位置。如：come here(来这儿)，come to school(来上学)，go there(去那儿)，go to school(去上学)。
2. 两者之后均可用 and 来代替一个表目的的不定式。如：
Come and have a drink. 来喝一杯。
He went and bought some envelopes. 他去买了些信封。
3. come 之后可接不定式，表示经过某一过程而发生某一情况，常译为“开始”“渐渐地”“终于”，但是动词go不能这样用。如：
How did you come to know her? 你是怎么认识她的?
You'll come to understand your parents someday. 你总有一天会理解你的父母。
4. come 和 go 之后均可接现在分词，但有区别：
(1) come+现在分词，主要用来说明“来”的方式。如：
He came running to welcome us. 他跑过来欢迎我们。
The children came running to meet us. 孩子们跑着来迎接我们。
A large stone came flying through the window. 从窗外扔进来一块大石头。
另外，该结构还可用来谈论体育和娱乐活动，与go doing sth用法相似，只是“方向”不同。如：
Would you like to come sailing? 你愿意来坐船游览吗?
Come swimming with us tomorrow. 明天跟我们一起游泳吧。
Why don't you come ice-skating with us tonight? 今晚来和我们一起溜冰好吗?
(2) go+现在分词，漏禅表示“去做……”，这类词组大多与体育、娱乐、日常生活等有关。如：
We often go swimming together. 我们常一道去游泳。
Let's go boating this afternoon. 今天下午我们去划船吧。
He finished lunch and went shopping. 他吃完午饭而后去买东西。
另外，该结构有时还可表示警告，用于建议做某事不好的事，此时多用于否定句。如：
Don't go saying that! 不要这样讲话!
Don't go looking for trouble, Maria. 不要去找哪拿麻烦了，玛丽亚。
You shouldn't go boasting about your achievements. 你不应当夸耀你的成就。
5. come 和 go 都可用作连系动词，表示事物状态的变化。如：
The handle has come loose. 这个把柄松了。
The children must not go hungry. 孩子们不应挨饿。
两者之后所接形容词通常各有其特点，有时还可从好坏方面去区别：即 come 用于“好”的变化，go 用于“坏”的变化。如：
Her dream has come true. 她的梦想实现了。
Fish soon goes bad in hot weather. 大热天鱼很容易坏。
另外，表示人的生理变化通常用 go，如go blind(变瞎)，go deaf(变聋)，go grey(两鬓渐白)等，但是go通常不与 old, ill, tired 等连用。
6. come 有时可以表示参加到对方的活动之中去(即使这种运动方向本身要求用 go)。如：
A：Will you come to see me tonight? 今晚来看我好吗?
B：Yes, I'll come. 好，我来。
A：Please come at once. Dinner is ready. 晚餐准备好了，请快来。
B：OK, I'm coming. 好，我就来。(若用 Oh, I'm going. 对方可能会理解为“噢，我要出去”。)
一般说来，在这种情况有以下3点需注意：
(1) 表示到听话人(包括收信人)那儿去，通常用 come。如：
I'll come to see you one of these days. 过几天我来看你。
(2) 邀请对方一起去某地，可用 come 或 go。一般说来，用 come含有一种自己决定要去的意味，而用 go 则含有一种请求和商量的意味。如：
Would you like to come [go] with us? 你和我们一起去好吗?
(3) 表示“我同你一起去”这样的意义时，可用 come 或 go。如：
I will come [go] with you. 我和你一起去。
【篇二】2021年上半年英语四级语法用法详解
1. Raise和rise都有“上升”的意思，记住下面2句话：
Raise是及物动词，后面必须有宾语，就是“某人把某物举起来”。
Rise是不及物动词，后面不能加宾语，也就是说“某人、某物自己升起来”。
比如：
He raised his right hand. 他举起了右手。(是他把手举起来的，所以用raise)
I raised the box above my head. 我把盒子举过了头顶。(盒子是我举起的，所以用raise)
The waves rose and fell. 波浪起起伏伏。(波浪是自己动的，所以用rise)
Smoke rose into the sky. 空中升起了烟。(烟也是自己飘的，所以用rise)
2. Raise和rise都有“增长”的意思，同样地：
Raise是及物动词，后面必须有宾语。
Rise是不及物动词，后面不能加宾语。
比如：
We will have to raise our fees. 我们需要提高费用。(raise后面一定要有宾语)
Prices are rising rapidly. 价格快速上涨。(rise后面一定不能有宾语)
3. 在英式英语里，raise只能作动词、不能做名词，rise既可以作动词、也可以作名词
比如：He asked for a pay rise.
在美语里，raise则可以作名词，表示“加薪”。
比如：She offered me a raise.
明白了吗?填空——>
We ___ our heads to watch the sun ___ over the bridge.
你觉得是A. raise / rise 还是B. rise / raise 呢?
We raised our heads to watch the sun rise over the bridge. 我们抬起头，望着太阳从桥上升起。(我们的头当然要我们抬起来，所以用raise;太阳是自己升升落落的，所以用rise。)
【篇三】2021年上半年英语四级语法用法详解
