Unit2:不定式
1.不定式的被动形式
当不定式与逻辑主语之间是被动关系时 即不定式的逻辑主语是不定式所表示动作的承受者不定式一般要用被动形式。其被动式可以分为两种一般式和完成式。
(1) 一般式to be done表示不定式动作在谓语动词之后或者同时发生。
It is a great honor to be invited to speak here. 很荣幸被邀请在这里讲话。
The novel is said to be published next month. 据说这本小说下月要出版。
(2) 完成式 to have been done 表示不定式动作发生在谓语动词之前。
The book is said to have been translated into six languages.
这本书据说已经被翻译成六种语言。
The boss preferred to have been given more work to do.
老板宁愿被分给更多的工作做。
被动 一般式 to be done 完成式 to have been done
2.不定式被动形式的作用
(1)作主语
It's an honor to be invited to the ceremony.
很荣幸被邀请赴宴。
It's a pity to be kept in the house in such fine weather.
在这样好的天气被关在家里真是遗憾。
(2)作表语
The letter is to be sent by airmail. 这封信笺要空邮。
(3) 作宾语
She didn't like to be treated as a child.
她不喜欢被当成孩子。
The boy asked to be given an opportunity to try again.
那男孩要求给他再试一次的机会。
(4)作宾语补足语

(5)作定语
He was the last one to be asked to speak at the meeting.
他是最后一个在会上被邀请发言的人。
(6)作状语
His mother left the small village never to be seen again.
他母亲离开了那个小山村，再也没有人见过她。
3.不定式有些要注意的地方
(1) 感官动词和一些使役动词的不定式的主动形式要省去to但在变成被动语态后需要加上to能这样用的动词或动词词组有make have let seehear notice listen to watch等。
如：We often see him act like that. He is often seen to act like that.我们常常看到他那样做。
(2)在can't help buthave nothing to do but结构中介词but后的不定式省去to。
如：I can't_help_but suspect his motive. 我不禁怀疑起他的动机。
I have nothing to do but watch TV. 我没什么事情可做除了看电视。
(3)不定式有时要用主动形式表示被动意义
①形容词以及含有形容词的名词后的不定式，一般用主动形式表示被动意义 其中形容词常见的有easy difficult importantimpossible等。
如：The work is impossible to finish in two days. 工作不可能两天之内完成。
English is not so easy to learn. 英语并不好学。
① 一些固定用法 如“挨骂 受责备 受批评” 用be to blame “(东西等)出租”用to let。
V-ing 的用法：
1.作主语
Swimming is good for health.
2. 作表语 Teaching is learning.教学相长.
注意：1)动名词和不定式都可以作主语，动名词作主语表示一般或抽象的多次性行为，不定式作主语往往表示具体的或一次性的动作。
如：
Playing with fire is dangerous. (泛指***)
To play with fire will be dangerous.(指一具体动作)
2). V-ing形式和不定式都要有对称性;当主语是不定式时，表语也用不定式;反之，当主语是 V-ing 形式时，表语也用 V-ing 形式。
To see is to believe.= Seeing is believing.
3). It’s no use (good) doing sth
It’s a waste of time doing sth
it 作形式主语, 只用V-ing,不用不定式。
※ It is + adj. + (for sb ) to do sth
It is no use crying over spilt milk.覆水难收。
It is a waste of time talking (talk) to him .
It is important for me to learn (learn) English .
3.作宾语 V-ing 形式既可作动词的宾语, 也可作介词的宾语。
We would appreciate hearing from you.我们会珍惜你的来信。

Unit4：定语从句
1. 关系代词 that, which (物) that, who, whom(人)whose(人和物)
①关系代词在从句做主语，宾语，表语。当做宾语时，可以省略。
A plane is a machine that can fly.(that做主语，先行词是物)
The book (which) I gave you was worth $10.(which先行词是物，在从句中作宾语可省，) She isthe pop star (that) I want to see very much.(that先行词是人，在从句中做宾语可省)
②who在从句中多做主语，whom只能做宾语，(介词和动词后)
Do you know the man who is talking with your mother?(who在从句中做主语，先行词是人)
The boy (whom) she loved died in the war.(whom在从句中做宾语，可省)
③ whose先行词即可是人也可是物。
I like those books whose topics are about history. The boy whose fatherworks abroad is my deskmate.
2. 关系副词
where 在从句中作地点状语 when 在从句中作时间状语 why 在从句中作原因状语 I will never forget the daywhen we met there.
This is the house where I was born.
I can’t imagine the reason why he turned down my offer.
三、介词/介词短语+关系代词(which, whom)
Mr. Smith is the person with whom I am working. This is the hotel in whichyou will stay.
关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用。
例如：There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。
Beijing is the place where(in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer?这就是他拒绝我们帮助他的理由吗?
四、 限制性定语从句和非限制性定语从句
1. 形式不同
2. 作用不同
限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意不完整或概念不清;而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意仍然清楚、完整：
3. 翻译不同 He is the man whose car was stolen. 他就是汽车被窃的那个人。 I’ve invited Jim,who lives in the next flat. 我请了吉姆，他就住在隔壁。
4. 先行词不同
五、 as引导的定语从句 as可以引导限制性和非限制性定语从句，在从句中做主语，宾语和表语。翻译成“像?一样”或“像” such?as像??一样，之类 the same?as 和??一样
He is such a clever boy as everyone likes.(as在从从句中做宾语，)
That’s the same tool as I used last week.
六、 as引导的定语从句和which的区别
①which 限制性非限制性位于句后修饰整句或先行词
Beijing, which is the capital of China, is a very beautiful city.
As is well known, he is a famous film star in the 1980s.
② as 多 和 被 动 语 态 连 用 ， be known, be said, be reported, be announced, beexpected等
③当非限制性定语从句是否定时，只能用which。
He came here very late, which was unexpected.
七、 特殊情况
只能用that的情况：
1.先行词为all, everything, anything, nothing, little, much,等不定代词时
2.先行词被all, any, every, each, much, little, no, some, few等修饰时
3.先行词有形容词最高级修饰时
4.先行词有序数词修饰时
5.先行词既指人又指物时
6.先行词被the only, the very修饰时
7.句中已经有who或which时，为了避免重复时
例如：
1.He told me everything that he knows.
2.All the books that you offered has been given out.
3.This is the best film that I have ever read.
4.We talked about the persons and things that we remembered.
5.He is the only man that I want to see.
6.Who is the man that is making a speech?
二、 只能用which不能用that的情况:
1. 非限制性定语从句
2. 介词+which
3. the way 做先行词时，定语从句可由that, in which 引导或不用引导词。
4. 当先行词是point, situation, stage等时，引导词用where.
