2.一般疑问句

3.there be 句型
There was an apple on the table last night.
Was there an apple on the table last night
一般过去时注意事项:
1.注意主句与从句中时态的一致性
如果主句用了过去时,从句中一般也要用过去式,或者过去进行时、过去完成时等。例如:
He believed that he was right. 他相信自己是对的。
I didn’t know you were here. 我不知道你在这儿。
I thought they were with you. 我以为他们和你在一起。

2.在口语中, 一般过去时并不一定指真正的过去,而只是表示一种礼貌性语气。例如:
I wondered (wonder) if you could do me a favor. 不知你可否帮我一个忙。
I wanted (want) to ask if I could borrow your car. 我想问问可否借用你的车。
I hoped (hope) you could (can) give me some advice. 我希望你能帮我出点主意。
Did (Do) you want to see me? 你想见我吗?

3.used to
used to 是一个词组,表示“过去曾经是……而现在已经停止了”的动作。例如:
I used to work fourteen hours a day. 我过去常常一天干十四个小时。(而现在不这样了)
I used to take a walk in the morning.我过去是在早晨散步。(而现在不在早晨散步了)
一般过去式用法:
(1)一般过去时表示在过去某个特定时间发生,也可以表示过去习惯性、经常性的动作。
一般过去时不强调动作对现在的影响,只说明过去的事情。
句式:主语+动词过去式+宾语+其它
I had a word with Julia this morning.今天早晨,我跟茱莉雅说了几句话。
He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子,抽烟抽得可凶了。

(2) 一般过去时常与表示过去的时间状语或从句连用,如:
yesterday,last week ,in  the  past ,in 1993,at that time,once,during the war,before,a few days ago,when 等等.
(句子中谓语动词是用一般过去时还是用现在完成时,取决于动作是否对现在有影响)。
Have you had your lunch? 你吃过午饭了吗?(你现在不饿吗?)
Yes,I have. 是的,我已经吃过了。(已经吃饱了,不想再吃了。)
When did you have it? 你是什么时候吃的?(关心的是吃的动作发生在何时。)
I had it about ten minutes ago. 我大约是十分钟以前吃的。)
Used to do something 表示过去常做而现在已经停止了的习惯动作。
I used to work fourteen hours a day. 我过去常常一天干十四个小时。
I ate it at 6:45。我在六点四十五分吃了。

(3)带有确定的过去时间状语时,要用过去时。如:
yesterday(昨天)、two days ago…(两天前…… )、last year…(去年…)、the other day(前几天)、
once upon a time(很久以前)、 just now(刚才)、in the old days(过去的日子里)、before liberation(解放前…)、
When I was 8 years old(当我八岁时…)、at+一个时间点
Did you have a party the other day?前几天,你们开了晚会了吗?
Lei Feng was a good soldier.雷锋是个好战士。
注:在谈到已死去的人的情况时,多用过去时。

(4)表示过去连续发生的动作时,要用过去时。这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。
The boy opened his eyes for a moment,looked at the captain,and then died.
那男孩把眼睛张开了一会儿,看看船长,然后就去世了。

(5)表示过去一段时间内经常或反复的动作。常与always,never等连用。
Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。
(只是说明她过去的动作,不表明她现在是否常带着伞。)
比较:
Mrs. Peter always carries an umbrella.彼得太太老是带着伞。
(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞)
Mrs. Peter is always carrying an umbrella.彼得太太 总是带着一把伞。
(表示说话者对这一动作或行为厌烦)
I never drank wine.我以前从不喝酒。
(不涉及到现在,不说明现在是否喝酒)

(6)如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了)
He used to drink alcohol.他过去喝酒。
(意味着他现在不喝酒了。喝酒这个动作终止了)
I used to take a walk in the morning.我过去是在早晨散步。
(意味着现在不在早晨散步了)
比较:
I took a walk in the morning.我曾经在早晨散过步。
(只是说明过去这一动作)

(7)有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时。
I didn''t know you were in Paris.我不知道你在巴黎。
(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)
I thought you were ill.我以为你病了呢。
(这句话应是在说话之前,我以为你病了。但是现在我知道你没病)
一般过去时三变技巧:
一变:肯定句变为否定句
技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.

二变:陈述句变为一般疑问句
技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如:
He could pack his things himself. → Could he pack his things himself?
技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如:
Mr Li looked very old. → Did Mr Li look very old?

三变:陈述句变为特殊疑问句
技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
They gave the concert last night. → When did they give the concert?
技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
The accident happened near the station. → Where did the accident happen?
一般疑问句:
是疑问句的一种。通常用yes,no来回答的疑问句叫做一般疑问句。口语中若无特殊含义,句末用升调。
其结构是:系动词be/助动词/情态动词+主语+其他成分? 
通常回答为:   
肯定:Yes+主语+提问的助动词   
否定:No+主语+提问的助动词+not 
例如:
Are you from Japan?   Yes, I am./No, I'm not.
Do you live near your school? Yes, I do./No, I don't. 
Can you speak French?  Yes, I can./No, I can't.
一般疑问句的特性:
1.将陈述句变为一般疑问句时,如句中有be 动词(am/ is/ are)时,可直接将它们提至主语前。
如主语为第一人称,应将其改为第二人称。如:
I'm in Class 2Grade 1. →Are you in Class 2Grade 1﹖
We're watching TV. →Are you watching TV﹖
2.陈述句中有情态动词(can、may、must …)时,也可直接将它们提至主语前,即可成为一般疑问句。如:
He can swim now. →Can he swim now﹖
The children may come with us. → May the children come with us﹖
3.陈述句中只有一个实义动词作谓语且其时态为一般现在时,变为一般疑问句时要在句首加do或does主语后的实义动词用原形。如:
I like these animals. →Do you like these animals﹖
She wants to go to the movies. → Does she want to go to the movies﹖
4.一般疑问句一般读升调(↑)
5.一般疑问句有时不用yes或 no 回答。如:
Are they in town now﹖
I think so.
May I sit here﹖
Certainly.
Does he like soccer﹖
Sorry I don't know.
6. 一般疑问句的第一单词总是虚词,读的时候要读轻声。
陈述句变为一般疑问句技巧:
根据一般疑问句不同的家族,可以用不同的方法将陈述句变为相应的一般疑问句。
1、第一家族:含be动词或情态动词的句子
秘诀:一调二改三问号
一调:即把句中的be或情态动词调到主语前;
二改:改换主语称谓,即将句中的主语Imy minesweourours等。第一人称分别改为相应的第二人称youyour yours等;
三问号:句末的句号改为问号。如:
Eg. I am an English teacher.    →    Are you an English teacher?
Eg. We can speak English fluently.   →    Can you speak English fluently?

2、第二家族:含行为动词(或称为实义动词)的句子
秘诀:一加二改三问号
一加:即在句首加助动词Do或Does;
二改:1、把谓语动词改为原形;2、改换主语称谓(同第一家组);
三问号:句末的句号改为问号。
Eg. We read English every morning. → Do you read English every morning?
Eg. Tom’s father listens to English on the radio every evening. →Does Tom’s father listen to English on the radio every evening?
特别注意:对于第二家族一定要注意动词的还原,因为时态与数的变化已经体现在助动词上了。

3、加强记忆口诀:
肯变一,并不难,can 或be提在前;
谓语若为行为动,do 或does句首用。
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。

宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。
宾语从句连接代词主要有:
who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever 等。

宾语从句的特点:
1.宾语从句可以作及物动词、介词及形容词的宾语。
2.宾语从句的语序一律用陈述句语序。
3.连接词that引导宾语从句在句中无词义,不充当句子成份,多数情况下可以省略。
4.whether 和 if 都可引导宾语从句,但 whether后可紧跟or not;whether从句可作介词的宾语。
5.如果从句太长,可以用形式宾语it.

宾语从句的时态:
1.主句是一般现在时,从句根据实际情况使用任何时态。
例句:The headmaster hopes everything goes well.
2.主句是过去时态,从句须用过去时态的某种形式。
例句:She was sorry that she hadn’t finished her work on time.
3.当宾语从句表示的是一个客观真理或者事实时,即使主句是过去时,从句也用一般现在时态。
例句:The teacher told his class that light travels faster than sound.
4. 如果从句的动作发生在主句之前,则从句要用过去完成时态。 

宾语从句的语序:
A. 宾语从句必须用陈述语序。   
False: He is wondering when can he finish this difficult job.   
Right: He is wondering when he can finish this difficult job.
B. 有时候可以用it 作形式宾语,而把真正的宾语从句放在后面。    
Bad: I thought that he could finish this job in just two hours impossible.   
Good: I thought it impossible that he could finish this job in just two hours.  
C. 带有宾语从句的复合句的否定形式一般是否定主句。
Bad: I think he doesn’t like the English teacher.   
Good: I don’t think he likes the English teacher. 
D.  主句一般过去时态,从句也要用过去时态。
False: He wanted to know why he is crying in the corner.   
Right: He wanted to know why he was crying in the corner

宾语从句的否定转移:
主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等。
并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。
I don’t think he will come to my party.而不能说成I think he won’t come to my party.
我认为他不会来我的舞会.
I don’t believe that man is killed by Jim,is he?
我认为那个人不是Jim所杀的,是不是?
如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式。
We find that he never listens to the teacher carefully,does he?
我们发现他从来不仔细听老师讲课,是不是?


宾语从句中引导词的用法比较
在复合句中作主句的宾语,引导词有:
连词:that (that 常可省略),whether, if
代词:who, whose, what ,which
副词:when ,where, how, why 等。

(一)that引导的宾语从句(在非正式场合that可以省略)
1.可跟that从句做宾语的动词有:
say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句:The boy believes that he will travel through space to other planets.
注意事项:当主句谓语动词是 think, believe, suppose, expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。
例句:I don’t think it is right for him to treat you like that.

2.在以下情况中that不能省略
a.当句中的动词后接多于两个由that引导的宾语从句时,第一个that可省,但后面的that不可省。
例句:He said (that) you were too young to understand the matter and that he was asked not to tell you.
b.当主句的谓语动词与that宾语从句之间有插入语时,that一般不可省。
例句:Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.
c.当that从句是双宾语中的直接宾语时,that不可省。
例句:I can’t tell him that his mother died.
d.注:许多带复合宾语的句子,that引导的宾语从句经常移到句子后部,而用it作形式宾语。
例句:I find it necessary that we should do the homework on time.

(二)由whether,if 引导的宾语从句
1.由whether(if)引导的宾语从句,实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。
一般说来,在宾语从句中whether与if可以互换使用,但在特殊情况下if与whether是不能互换的。
例句:I wonder whether(if) they will come to our party.

2.只能用whether,不能用if引导的宾语从句
a.在带to的不定式前
例句:We decided whether to walk there.
b.在介词的后面
例句:I’m thinking of whether we should go to see the film.
c.在动词后面的宾语从句时
例句:We discussed whether we had a sports meeting next week
d.直接与or not连用时
例句:I can’t say whether or not thet can come on time.

3.只能用if不能用whether引导的宾语从句
a.if引导条件状语从句,意为“如果”
例句:The students will go on a picnic if it is sunny.
b.if引导否定概念的宾语从句时
例句:He asked if I didn’t come to school yesterday.
c.引导状语从句even if(即使)和as if(好象)时
例句:He talks as if he has known all about it.

if,whether在宾语从句中的区别
a.if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if
b.少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether. 
c. whether后可以加or not,但是if不可以.
d.在不定式前只能用whether.
(如:I can’t decide whether to stay. 我不能决定是否留下。)
e.避免歧异时,我们常用whether而不用if.

(三)连接代词和连接副词引导的宾语从句
这样的宾语从句实际上是由特殊疑问句变化而来的,宾语从句要用陈述句语序。
用于这种结构的动词常常是:see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。
1.英语中的连接代词有:who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。
例句:Can you tell me whom you are waiting for?
2.英语中的连接副词有:when,where,why,how,在句中担任状语的成分。
例句:None of us knows where these new parts can be bought.


简化宾语从句常用六法:
方法一:
当主句谓语动词是hope, decide, wish, choose, agree, promise等,
且宾语从句的主语与主句主语一致时,宾语从句可简化为不定式结构。
例如:
Li Ming hopes he will be back very soon.
→Li Ming hopes to be back very soon.
We decided that we would help him.
→We decided to help him.

方法二:当主句谓语动词是know, learn, remember, forget, tell等动词,
且主句主语与从句主语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
She has forgotten how she can open the window.
→She has forgotten how to open the window.
注:当主句谓语动词是tell, ask, show, teach等动词,
且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。例如:
Could you tell me how I can get to the station?
→Could you tell me how to get to the station?

方法三:当主句的谓语动词是order(命令),require(需要)等时,
如果主句和从句的主语不一致,宾语从句可简化为“名词(代词)+不定式”结构。例如:
The headmaster ordered that we should start at once.
→ The headmaster ordered us to start at once.

方法四:某些动词后的宾语从句,可以用介词加动名词(短语)等其他形式简化。例如:
He insisted that he should go with us.
→He insisted on going with us.
The poor boy doesn’t know when and where he was born.
→The poor boy doesn’t know the time and the place of his birth.

方法五:某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。例如:
Liu Ping found that there was a wallet lying on the ground.
→ Liu Ping found a wallet lying on the ground.

方法六:动词seem后的宾语从句,也可以用不定式(短语)来简化,但句型需要进行适当的变化。例如:
It seemed that the boys were going to win.
→The boys seemed to win.
除上述方法外,还有一些特殊句式的转化。例如:
I found that it was difficult to learn English well.
→I found it difficult to learn English well.
Soon we found that the ground was covered with thick snow.
→Soon we found the ground covered with thick snow.
They found that the box was very heavy.
→They found the box very heavy



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。
