关系代词:
用来引导定语从句。它代表先行词,同时在从句中作一定的句子成分。
关系代词有主格,宾格和属格之分,并有指人与指物之分,它在先行词和定语之间起纽带作用。
主要的关系代词有who,whom,whose,which和that。
①who指人,在定语从句中作主语或宾语;
whom指人,在定语从句中作宾语;
whose在定语 从句中作定语,其先行词既可以是人也可以是物。
例如:The teacher who/whom you want to see has come.
②which指物,在定语从句中作主语或宾语。 
例如:Here is the coat which will be made to you.
③that多指物,有时也指人,在定语从句中作主语或宾语。
例如:I have eaten bread that/which he gave to me.

关系代词的基本用法:
(1)引导定语从句
关系代词代表先行词,同时在从句中作一定的句子成分,例如:
The girl whom I spoke to is my cousin. 跟我讲话的姑娘是我表妹。
(该句中whom既代表先行词the girl,又在从句中作介词to的宾语。)
This is the pencil whose point is broken.这就是那个折了尖的铅笔。
(whose 指物,在限定性定语从句中作定语)
He came back for the book which he had forgotten.他重新回来都忘记了他的那本书。
(which指物,在限定性定语从句中作宾语,可以省略)
(2)which为其先行词。例如:
He said he saw me there, which was a lie.他说在那儿看到了我,纯属谎言。
(3)其他用法
关系代词that在从句中作宾语或表语时可省略, 例如:
I've forgotten much of the Latin I once knew.我过去懂拉丁语,现在大都忘了。
He's changed. He's not the man he was.他变化很大,已不是过去的他了。
注释:关系代词在从句中作宾语时可省略,that在从句中作表语时也可省略。
非限定性定语从句中,不能用that作关系代词。


关系代词的语法注意:
1.常用that 不用which的情况:
①先行词为all, anything, everything, nothing, something等时。
I will do all (that) I can to help you.
②先行词被序数词、形容词最高级或the only, the very等所修饰时。
He was the only person that joined the army in his village that year.
③先行词既有人,又有物时
They talked about the people and the things (that)they remembered in the school.
④当主句是以who 或which开头的疑问句时, 定语从句用that 引导, 以避免重复。
Who is the boy that was here just now?
2. 若被修饰的名词充当从句介词宾语时
介词可提前于引导词之前,此时的引导词只能用whom 或which.
The pencil with which he was writing broke.
3. 当先行词为way时
其后的定语从句用in which或 that引导,也可不用引导词。
I don’t like the way (in which/that) he talks to me.

used to/be used to的分别:
①used to + do:"过去常常"表示过去习惯性的动作或状态,但如今已不存在。
Mother used not to be so forgetful.
②be used to + doing: 对……已感到习惯,或"习惯于",to是介词,后需加名词或动名词。
Scarf is used to taking a walk.(现在习惯于散步)
③used to 的用法 (否定式简写为usedn't) 过去经常,以前常常
This used to be a shabby house. (此房年久失修)
used to,would这两个词语都可以表示过去常做某事,有时可以换用。
used to do 强调过去习惯性的行为或状态,但是现在没有这种行为或状态了。因此,这个短语的内涵是今昔对比。


关系代词的用法:
一、不用that的情况
在引导非限定性定语从句时 (错)The tree, that is four hundred years old, is very famous here.
介词后不能用We depend on the land from which we get our food.

二、只能用that作为定语从句的关系代词的情况
a.在there be 句型中,只用that,不用which。
b.在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which。
c.先行词有the only, the very.(恰恰,正好).any. few. little. no. all 修饰时,只用that。
d.先行词为序数词、数词、形容词最高级时,只用that。
e.先行词既有人,又有物时。
Finally, the thief handed everything that he had stolen to the police.那贼最终把偷的全部东西交给了警察。

三、不能用关系代词Which 的几种情况
1.当先行词为all, little, much, few, everything, none 等不定代词时关系代词用that而不用which.

2.当先行词既有人又有物时,关系代词用that, 不用which.

3.当先行词有形容词最高级修饰时,关系代词用that, 而不用which.

6.当先行词被all, every, any, much, little, few, no等修饰时,关系代词用that,不用which.

8.在强调句型" It is ... that ..." 中,只用that,不用which.

9.在" such (the same) ... as ..." 句型中,关系代词要用as, 而不用which.
We need such materials as (not which) can bear high temperature.
10.表示" 正如... 那样 "," 正象..." 之意时,用as, 不用which.

11.As 引导的定语从句可以放在主句前面,也可以放在主句后面或主句中间,而由 which引导的定语从句只能放在主句后面。
As we all know, oceans cover more than 70% of the earth.

关系代词可以省略的情况:
1.关系代词which,whom,who,that在定语从句中作宾语时可以省略。
Here is the man (who/that/whom)you're been looking for.
2.当that在从句中作补语时可以省略。

3.在there be 结构中出现定语从句,或在定语从句中出现there be 时,用作主语的关系代词也可省略。

4.当由and,but,or等连词连接两个或两个以上的定语从句修饰一个先行词时,第一个关系代词可省,但第二,第三个不可省略。

特殊关系代词的用法:
关系词通常是用来引导定语从句的,但as,than和but这三个词却与which, who, that, where, when和why等典型的关系词不同。
三者本身具有常见的字面意义,前面有名词作先行词,但后面的定语从句却不像典型的定语从句。
这些既像连接词又像关系词的词,我们就姑且称它们为准关系词。
一、 as作为准关系代词出现在the same ... as, such ... as, 和as ... as等结构中。
这时, as前面通常要有名词;
as后面的从句意义上不像是通常的定语从句;
as需要在从句中充当一定的句子成分。
1. the same ... as
        1) as在从句中作主语
  She is the same person as came here last Sunday. 她就是上星期天来这儿的那个人。
  2) as在从句中作宾语
  This is the same watch as I lost while I was doing the sightseeing in Shanghai three months ago. 这块表跟我三个月前在上海观光时丢失的那块一样。
  3) as在从句中作be动词的表语
  China is not the same country as it used to be. 中国已今非昔比。
  4) as在从句中作行为方式状语
  You should learn to do housework in the same way as your mother does it. 你应该学会像你母亲那样做家务活。
2. such ... as
  1) as在从句中作主语
  Let children read such books as tend to make them better and brighter. 让孩子看那些容易让他们变得更好更聪明的书。
  2) as在从句中作宾语
  This is not such an interesting book as you just talked about. 这不是你们刚才谈到的那种有趣的书。
  3) as在从句中作be动词的表语
  Such a bad man as he is will be punished. 像他这样的坏人一定会受到惩罚。
3. as ... as
  1) 第二个as在从句中作主语
  He has as much money as is required. 他要多少钱就有多少钱。
  2) 第二个as在从句中作宾语
  I have as many friends as you (do). 我的朋友和你的朋友一样多。
  3) 第二个as在从句中作be动词的表语
  As is known to all, Taiwan is one of the Chinese provinces。众所周知,台湾是中国的一个省。

二、than作为准关系词 出现在more ... than, less ... than, fewer ... than等结构中。这时, than前面要有名词; than本身有比较意义,而且需要在从句中充当一定的句子成分。
  1. than在从句中作主语
  Take it easy, I have more money than is needed. 放心,我的钱比所需要的还要多。
  2. than在从句中作宾语
  I have more/fewer books than you (do). 我的书比你的多/少。
  3. than在从句中作be动词的表语
  He is a better boy than you (are). 他是一个比你更好的男孩。
三、but作为准关系词 本身含有否定意义,它前面的主句还有另一个否定意义。这时but在意义上相当于“who ... not ...”或“which/that ... not ...”。
  1.定语从句中有be动词,并将其改为含but的复合句时, be动词后面不能再有not
  There is no one who is not conccrned about his future. (= There is no one but is concerned about his future.) 没有人不关心自己的未来?
  2. 定语从句中有can, will, shall, must, may, should, ought to等助动词或情态动词,在将其改为含but的复合句时,这些助动词或情态动词后面不能再有not
  There is nothing that she can’t do. (= There is nothing but she can do.) 没有她做不到的事?
  3. 定语从句中有助动词do, does, did, 在将其改为含but的复合句时,应去掉do, does, did, 还原其后动词的时态及人称变化
  There is no one who doesn’t wish to make great achievements. (= There is no one but wishes to make great achievements.) 谁都希望自己将来能有所成就。
四、which的先行词:关系代词which的先行词可以是一个句子
  He said he saw me there, which was a lie。他说在那儿看到了我,纯属谎言。
说明:关系代词that在从句中作宾语或表语时可省略
  I've forgotten much of the Latin I once knew。 我过去懂拉丁语,现在大都忘了。  


形容词
简称adj.或a,形容词用来修饰名词或代词,表示人或事物的性质、状态,和特征的程度好坏与否,形容词在句中作定语,表语,宾语补足语。

三、作状语
形容词或形容词短语可作状语,形容词作状语时,可以看作是“being+形容词”结构的省略,可表示时间、原因、条件、方式、强调或伴随状况等意义。例如:

Rich or poor, young or old, we all have problems.不管是穷人还是富人,不管是年轻人还是老人,我们都有问题。
四、做表语

形容词的位置:
1.形容词一般放在名词前作定语

    All countries, rich and poor, should help one another. 所有的国家,无论穷富都应该互相帮助。

Do you have enough time(time enough)to prepare?你有足够的时间做准备吗?   
Maybe it will be a possible chance(chance possible)for you.或许它将成为一次可能的机遇。
6.有些形容词,置于名词之前与之后,含义不尽相同。例如:

 Do you have anything else to say?
10.由两个或两个以上的词组成的形容词词组修饰名词时须放在名词之后。
This is the book easy to read.
这是一本容易读的书。

注:在少数搭配中,也用介词 on。如:
He works on a farm. 他在农场工作。

3. 在某些搭配中,三者的区别与英国英语和美国英语有关:
in the street (英) / on the street (美) 在街上
in the road (英) / on the road (美) 在路上
in the team (英) / on the team (美) 在这个队
at the weekend (英) / on the weekend (美) 在周末
at weekends (英) / on weekends (美) 在周末
4. 有时三者的差别与搭配习惯和用法有关:
in bed / on the bed 在床上
in the tree (多指树外之物) / on the tree (多指树本身之物) 在树上

介词besides,but,except的用法区别:
 1. 三者都可表示“除外”,但 besides 表示一种累加关系,意指“除了什么之外,还有……”;
而 except 或 but 则表示一种排除关系,意指“除了什么之外,不再有……”。如:
Besides his wife,his daughter also went to see him. 除他妻子外,他女儿也去看过他(即妻子女儿都去看过他)。
Nobody went to see him except [but] his wife. 除他妻子外,没有一个人看过他(即只有他妻子去看过他)。
注:在否定句中,besides 也表示“除……之外不再有…… ”,与but, except 同义。如:
No one passed the exam besides [except] Jim. 除吉姆外,没一个人通过考试。

2. 关于 but 与 except:
(1) 两者都可表示“除……外不再有……”,但含义上略有差别:
but侧重指意义的几乎完整性,而 except 则侧重指后面除去的部分。比较:
All are here but one. 除一个人都到了。
All are here except one. 还有一个人没到。
(2) 在现代英语中,but 的介词用法十分有限,一般说来,它只能用在下列词语之后:
① no, no one, nobody, nothing, nowhere 等
② any, anyone, anybody, anything, anywhere 等
③ every, everyone, everybody, everything, everywhere 等
④ all, none 等
⑤ who, what, where 等
Everyone knows it but you. 除你之外大家都知道。
I haven’t told anybody but you. 除你之外,我没告诉任何人。
No one but he [him] showed much interest in it. 除他之外没有一个人对此有很大兴趣。
一般说来,若没有出现上述词汇,就不宜使用介词 but,否则可能造成错句。但是 except 却没有以上限制。比较:
正:The window is never opened except in summer. 除夏天外,这扇窗户从不打开。
误:The window is never opened but in summer.
(3) but 一定不能用于句首,except 通常不用于句首:
除我之外每个人都累了。
正:Everyone is tired but (except) me.
正:Everyone but (except) me is tired.
误:But (Except) me, everyone is tired.
注:except for 可用于句首,表示 except 的意思:
正:Except for me, everyone is tired.

3. 关于 except 与 except for:
except 主要用来谈论同类的东西,而 except for 则主要用来谈论不同类的东西,有时含有惋惜之意。如:
All compositions are well written except yours. 除了你的作文外,其他的作文都写得很好。
His composition is good except for a few spelling mistakes. 他的作文写得不错,只是有几处拼写错误。
注:若用于句首,则 except for 与 except 同义(但 except 通常不用于句首)。

4. 关于 except for 与 but for:
except for 主要表示排除,but for 主要表示一种虚拟条件(与虚拟语气连用)。如:
Except for me, everyone passed the exam. 除了我之外,大家都通过了考试。
But for my help, she would not have passed the exam. 若不是我的帮助,她就不会通过考试。
But for the atmosphere plants would die. 如果没有大气,植物就会死亡。
5. besides 除用作介词外,还用作副词,其意为“此外”、“而且”,可用于分句句首(通常用逗号隔开)或句尾。如:
I don’t want to go; besides, I’m too tired. 我不想去,而且我也太累了。
This car belongs to Smith, and he has two others besides. 这部车是史密斯的,此外他还有两部。

反义疑问句:
表示提问人的看法,没有把握,需要对方证实。
反意疑问句由两部分组成:前一部分是一个陈述句,后一部分是一个简短的疑问句,两部分的人称时态应保持一致。
1. 陈述部分肯定式+疑问部分否定式可记为前肯后否。 
2. 陈述部分否定式+疑问部分肯定式可记为前否后肯。
例如:This pencil is red, isn’t it? Yes, it is. / No, it isn’t. 
               This pencil isn’t red, is it? Yes, it is. / No, it isn’t.
速记:
前肯后否,前否后肯,前be后be,前无be后加助,时态一致。

反意疑问句的回答
前肯后否,前否后肯,根据事实从后往前翻译。如:
(1)They work hard,don’t they?他们努力工作,不是吗?
Yes, they do.对,他们工作努力。/No, they don't.不,他们工作不努力
(2)They don’t work hard, do they? 他们不太努力工作,是吗?
Yes, they do. 不,他们工作努力。/No, they don't. 是的, 他们工作不努力

否定反义疑问句的回答
当陈述部分为肯定式,反义疑问句为否定式时,其回答一般不会造成困难,一般只需照情况回答即可:
"It’s new, isn’t it?" "Yes, it is." “是新的,不是吗?”“是,是新的。”
"He wants to go, doesn’t he?" "No, he doesn’t." “他想去,不是吗?”“不,他不想去。”
此时,"Yes"即是,对前面"It's new."的肯定。

回答反义疑问句的原则
回答反意疑问句通常应根据实际情况来确定,
如有人问你You are asleep, aren’t you? 你应回答No, I’m not. 因为既然你能回答,肯定你还没有asleep。
但如果别人问你 You aren’t asleep, are you?(你还没有睡着,对吗),你也只能回答No, I’m not.(是的,还没有睡着),而不能回答为Yes, I’m not. 也不能回答成 Yes, I am.
“It is a beautiful flower,isn't it?” “It isn't a beautiful flower,is it?”
上述两句句子的回答肯定均为“Yes,it is."否定为“No,it isn't."
由上述例子可知,反义疑问句回答与句子本身所包含的中文肯定与否的含义并无太大关联,只需注意事实,肯定即用yes,否定用no,无需考虑句子原本是前否后肯或是前肯后否。

口诀:
反意疑问并不难,陈述疑问句中含。
前后肯否恰相反,否定词缀不能算。
主谓时态要一致,特殊情况记心田。
实际情况来回答,再把yes和no拣。
综上所述,反义疑问句回答就是按实际情况回答。
对反意疑问句的回答,无论问题的提法如何,如果事实是肯定的,就用yes,事实是否定的,就要用no。
要特别注意陈述句部分是否定结构,反意疑问句部分用肯定式提问时,回答yes或no与汉语正好相反。这种省略回答的yes要译成“不”,no要译成“是”。
例:
—He likes playing football, doesn’t he? 他喜欢踢足球,不是吗?
—Yes, he does. / No, he doesn’t. 是的。/ 不是。
—His sister didn’t attend the meeting, did she? 他妹妹没有参加会议,是吗?
—Yes, she did. / No, she didn’t. 不,她参加了。/ 是的,她没参加。

   It is unfair, isn't it? 这不公平,是吧?   
11.含有否定含义的词在陈述部分作动词的宾语时,其反意疑问句用肯定结构,也可以用否定结构。例如:

而当must作推测意义“一定 是;必定”讲时,反意疑问句则需根据must后的动词原形选用相应的形式。例如:    
He must work hard at physics, mustn't he? 他必须努力学物理,是吧?   
Tom must be at home,isn't he? 汤姆一定在家,是吧?
定语从句:
担任定语动能的句子称为定语从句。定语从句在句中的作用相当于形容词,故又称为形容词性从句。
定语从句所修饰的词叫先行词;定语从句一般用关系代词或关系副词来引导,关系词放在先行词与定语之间起连接作用,同时又作从句中的一部分。

定语从句的分类:
根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。
限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去;
非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
1.由that引导的定语从句
一般情况下that可指人或物,可以代替who,whom和which,在从句中作主语或谓语动词的宾语,但不能作介词的宾语。如:
The comrade that(who)is speaking at the meeting is an advanced worker.
正在会上讲话的那个同志是个先进工人。
Is this the doctor that(whom)you talked about yesterday?
这就是你们昨天谈论的那位医生吗?
The letter that(which)I received yesterday was from my father.
昨天我收到的信是我父亲寄来的。
2.由who,whom和whose引导的定语从句
who在从句中作主语,whom在从句中作宾语,whose在从句中作定语。如:
This is the thief who stole my bike.这就是偷我自行车的那个贼。
He is the boy whom you wanted to find.他就是你想要找的那个男孩。
The girl whose mother is a doctor is waiting for you outside.妈妈是个医生的那个女孩在外面等你。
3.由which引导的定语从句
which指物,在从句中作主语或谓语动词的宾语。如:
The book which Mum bought me last week is called“Red Star Over China”.
妈妈上周买给我的那本书名叫《西行漫记》。
The house which Lu Xun once lived in is now the Lu Xun Museum.
鲁迅曾经住过的那所房子现在是鲁迅博物馆。
4.由where,when和why引导的定语从句
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。如:
I will never forget the day when I joined the League.我永远忘不了我入团的那一天。
He will go back to the school where he studied next week.下周他要回到他曾经学习过的学校。
I don't know the reason why he quarreled with Zhang Lin.我不知道他同张琳吵架的原因。
[注意点]
关系代词在定语从句中作宾语时,关系代词常省去。如:
The play(which)I watched just now had been on twice on Channel
我刚才看的那个戏剧在3频道上已上演了两次。


限定性定语从句:
1. that即可代表事物也可代表人,which代表事物;
它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。
而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略
4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
5. where是关系副词,用来表示地点的定语从句
6. when引导定语从句表示时间
〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
By the time you arrive in London, we will have stayed there for two weeks.
I still remember the first time I met her.
Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.
7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格
8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导

非限定性定语从句
非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立
1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which
Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed.
人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。
I like the music for the very reason that(for which) he dislike it.
我出于某种原因喜欢这种音乐,而他恰恰与我相反。
We arrived the day that(on which) they left.
刚好我们到的那天他们走了。
3. 有时as也可用作关系代词
4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物
限定性定语从句口诀:
(口诀一)  
定语从句真奇妙,  
关系代(副)词来引导,  
定语从句分两种,  
是否限定看逗号。  
(口诀二)  
which指物who指人,  
地点where时间when,  
that人或物均可,  
why之前是reason。  
(口诀三)  
从句当中作宾语,  
whom可以代替who,  
为了句子更简练,  
关系代词可省去。  
(口诀四)  
关系若是表所属,  
whose用法不可无。  
除此之外还有啥,  
whom, which加of。  
(口诀五)  
关系代词不一般,  
介词经常用在前,  
此时不用that, who,  
which, whom才安全。
