Unit2:不定式
1.不定式的被動形式
當不定式與邏輯主語之間是被動關系時 即不定式的邏輯主語是不定式所表示動作的承受者不定式一般要用被動形式。其被動式可以分為兩種一般式和完成式。
(1) 一般式to be done表示不定式動作在謂語動詞之后或者同時發(fā)生。
It is a great honor to be invited to speak here. 很榮幸被邀請在這里講話。
The novel is said to be published next month. 據(jù)說這本小說下月要出版。
(2) 完成式 to have been done 表示不定式動作發(fā)生在謂語動詞之前。
The book is said to have been translated into six languages.
這本書據(jù)說已經(jīng)被翻譯成六種語言。
The boss preferred to have been given more work to do.
老板寧愿被分給更多的工作做。
被動 一般式 to be done 完成式 to have been done
2.不定式被動形式的作用
(1)作主語
It's an honor to be invited to the ceremony.
很榮幸被邀請赴宴。
It's a pity to be kept in the house in such fine weather.
在這樣好的天氣被關在家里真是遺憾。
(2)作表語
The letter is to be sent by airmail. 這封信箋要空郵。
(3) 作賓語
She didn't like to be treated as a child.
她不喜歡被當成孩子。
The boy asked to be given an opportunity to try again.
那男孩要求給他再試一次的機會。
(4)作賓語補足語
I'd like my bedroom to be cleaned. 我想整理一下我的臥室。
(5)作定語
He was the last one to be asked to speak at the meeting.
他是最后一個在會上被邀請發(fā)言的人。
(6)作狀語
His mother left the small village never to be seen again.
他母親離開了那個小山村，再也沒有人見過她。
3.不定式有些要注意的地方
(1) 感官動詞和一些使役動詞的不定式的主動形式要省去to但在變成被動語態(tài)后需要加上to能這樣用的動詞或動詞詞組有make have let see hear notice listen to watch等。
如：We often see him act like that. He is often seen to act like that. 我們常?？吹剿菢幼?。
(2)在can't help buthave nothing to do but結構中介詞but后的不定式省去to。
如：I can't_help_but suspect his motive. 我不禁懷疑起他的動機。
I have nothing to do but watch TV. 我沒什么事情可做除了看電視。
(3)不定式有時要用主動形式表示被動意義
①形容詞以及含有形容詞的名詞后的不定式，一般用主動形式表示被動意義 其中形容詞常見的有easy difficult important impossible等。
如：The work is impossible to finish in two days. 工作不可能兩天之內(nèi)完成。
English is not so easy to learn. 英語并不好學。
① 一些固定用法 如“挨罵 受責備 受批評” 用be to blame “(東西等)出租”用to let。
V-ing 的用法：
1.作主語
Swimming is good for health.
2. 作表語 Teaching is learning.教學相長.
注意：1)動名詞和不定式都可以作主語，動名詞作主語表示一般或抽象的多次性行為，不定式作主語往往表示具體的或一次性的動作。
如：
Playing with fire is dangerous. (泛指玩火)
To play with fire will be dangerous.(指一具體動作)
2). V-ing形式和不定式都要有對稱性;當主語是不定式時，表語也用不定式;反之，當主語是 V-ing 形式時，表語也用 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 作形式主語, 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.覆水難收。
It is a waste of time talking (talk) to him .
It is important for me to learn (learn) English .
3.作賓語 V-ing 形式既可作動詞的賓語, 也可作介詞的賓語。
We would appreciate hearing from you.我們會珍惜你的來信。

Unit4：定語從句
1. 關系代詞 that, which (物) that, who, whom(人)whose(人和物)
①關系代詞在從句做主語，賓語，表語。當做賓語時，可以省略。
A plane is a machine that can fly.(that做主語，先行詞是物)
The book (which) I gave you was worth .(which先行詞是物，在從句中作賓語可省，) She is the pop star (that) I want to see very much.(that先行詞是人，在從句中做賓語可省)
②who在從句中多做主語，whom只能做賓語，(介詞和動詞后)
Do you know the man who is talking with your mother?(who在從句中做主語，先行詞是人)
The boy (whom) she loved died in the war.(whom在從句中做賓語，可省)
③ whose先行詞即可是人也可是物。
I like those books whose topics are about history. The boy whose father works abroad is my deskmate.
2. 關系副詞
where 在從句中作地點狀語 when 在從句中作時間狀語 why 在從句中作原因狀語 I will never forget the day when we met there.
This is the house where I was born.
I can’t imagine the reason why he turned down my offer.
三、介詞/介詞短語+關系代詞(which, whom)
Mr. Smith is the person with whom I am working. This is the hotel in which you will stay.
關系副詞when, where, why的含義相當于"介詞+ which"結構，因此常常和"介詞+ which"結構交替使用。
例如：There are occasions when (on which) one must yield. 任何人都有不得不屈服的時候。
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? 這就是他拒絕我們幫助他的理由嗎?
四、 限制性定語從句和非限制性定語從句
1. 形式不同
2. 作用不同
限定性定語從句用于對先行詞的意義進行修飾、限制和識別，如果去掉，就會造成句意不完整或概念不清;而非限定性定語從句用于對先行詞起補充說明作用，如果省略，句意仍然清楚、完整：
3. 翻譯不同 He is the man whose car was stolen. 他就是汽車被竊的那個人。 I’ve invited Jim, who lives in the next flat. 我請了吉姆，他就住在隔壁。
4. 先行詞不同
五、 as引導的定語從句 as可以引導限制性和非限制性定語從句，在從句中做主語，賓語和表語。翻譯成“像?一樣”或“像” such?as 像??一樣，之類 the same?as 和??一樣
He is such a clever boy as everyone likes.(as在從從句中做賓語，)
That’s the same tool as I used last week.
六、 as引導的定語從句和which的區(qū)別
①which 限制性非限制性位于句后修飾整句或先行詞
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 動 語 態(tài) 連 用 ， be known, be said, be reported, be announced, be expected等
③當非限制性定語從句是否定時，只能用which。
He came here very late, which was unexpected.
七、 特殊情況
只能用that的情況：
1.先行詞為all, everything, anything, nothing, little, much,等不定代詞時
2.先行詞被all, any, every, each, much, little, no, some, few等修飾時
3.先行詞有形容詞最高級修飾時
4.先行詞有序數(shù)詞修飾時
5.先行詞既指人又指物時
6.先行詞被the only, the very修飾時
7.句中已經(jīng)有who或which時，為了避免重復時
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的情況:
1. 非限制性定語從句
2. 介詞+which
3. the way 做先行詞時，定語從句可由that, in which 引導或不用引導詞。
4. 當先行詞是point, situation, stage等時，引導詞用where.
