答案：　A

＝The man about whom I talked at the meeting is from Beijing University.在会议中我与他谈话的那个人是从北京大学来的。

A．all of which　　　 B．all of them
C．none of whom　　　 D．none of them
解析：　考查定语从句。后半句是非限制性定语从句，修饰先行词students ，应用whom引导。因为前后两句之间没有并列连词，所以B、D两项不正确。
答案：　C
point，situation，case等，从表面上看它们不是表地点的，但却表示类似地点的意义，因此它们作先行词时，如果引导词在从句中作状语，那么这个引导词要用where；如果不作状语，则用关系代词that/which。
It’s helpful to put children in a situation where they can see themselves different.(where 作状语)
把孩子放在一个能使他们从另外一个角度认识自己的环境中对他们有益。

C．which　　　  D．that
解析：　point 为先行词，后面为定语从句，在定语从句中walk 为不及物动词，从句不缺少宾语，且表时间故用when引导。句意为：医生说，病人的治疗要持续到他能够安全稳当地行走为止。
答案：　B
1．as 与which 都可以代指主句中的一部分或整个句子的内容，有时可以互换。
He married her，as (which) was natural.
很自然地，他和她结婚了。
(2009?山东卷)Whenever I met her，which was fairly often，she greeted me with a sweet smile.
不管我何时遇见她，她都用甜甜的微笑迎接我，这是常事儿。
2．但在下列情况下一般只能用as。
(1)as引导的定语从句可以放在句首，而which 则不能。
As we know，more than seventy percent of the earth is covered with water.正如我们所知，地球表面的70%以上被水覆盖。
(2)as 表示“正如，正像”，而which 无此意。
此时，as从句中常有know，expect，happen，point out，plan，suggest 等单词或短语。
He came back home late，as we expected.
正如我们所料，他回家晚了。
(3)当先行词被the same，such 修饰时，定语从句需用as引导。

我买了一本跟你一样的书。
I’ll give you such things as you may need.
我将给你你需要的东西。

他将与他能发现的最漂亮的女孩结婚。

the same...as(指同样或同类的)，the same...that (指同一个)
This is the same watch as I lost.
这块表与我丢的那块一样。
This is the same watch that I lost.
这就是我丢的那块表。

A．the same；that　　　  B．the same；as
C．the same；where　　　 D．as the same；is
解析：　句意为：Black 夫人把警察带到她目睹抢劫案的那个地方。可见在以the same place 为先行词的定语从句中，从句缺少的是地点状语，因此用where。A、B两项中的引导词that，as均为关系代词，要在从句中作主语或宾语，故错误。
答案：　C

A．Which　　　  B．As
C．That　　　  D．It
解析：　as 引导的非限制性定语从句可以放在句首，which引导的定语从句不能放在主句的前面；that 不能引导非限制性定语从句。it 可以作形式主语，如果把句子中的逗号改为that，D项也正确。句意为：正像上文提到的那样，高中生的数量在增长。

答案：　B
5．(2011?黄冈检测)Beijing was attacked by such a terrible sandstorm ________few residents had ever experienced before.

答案：　B
13． Gun control is a subject________Americans have argued for a long time.
A．of which　　　 B．with which
C．about which　　　 D．into which

答案：　C

答案：　C
关系代词that与which的用法区别
(1)关系代词指代物，而引导词只用which不用that的情况：
①关系代词指物，作介词宾语的时候：
This is the question about which they have had so much discussion in the past few weeks.
这是他们在过去几周讨论了多次的问题。
②关系代词指前面的整个句子，引导非限制性定语从句时：
He failed in the exam，which made his father angry.
他考试不及格，这使他父亲很生气。
(2)that和which都指物时，在下列四种情况下只能用that而不能用which：
①当先行词是all，everything，something，nothing，anything，much，little，few等不定代词时。
There was little that I could do for you.我不能为你做什么。
That is all that I want to say.那就是我想要说的。
②当先行词被序数词和形容词最高级修饰时。
The first place that they visited in Guilin was Elephant Trunk Hill.在桂林他们所参观的第一个地方是象鼻山。
This is the best film that I have ever seen.
这部电影是我看过的最好的一部。
③当先行词被the very，the only，the just等修饰时。
This is the very dictionary that I want to buy.
这正是我要买的词典。
Mr Smith is the only foreigner that he knows.
史密斯先生是他唯一认识的外国人。
④当人和物同时作先行词时。
Do you know the things and persons that they are talking about?
你知道他们正在谈论的人和事吗？
⑤当主句的主语是疑问词who或which时。
Which is the bike that you lost？哪一辆是你丢失的自行车？
Who is the boy that won the gold medal？获金牌的小男孩是谁？
介词＋关系代词
(1)介词＋关系代词中介词的宾语只能是which或whom。
The gentleman about whom you told me yesterday proved to be a thief.你昨天告诉我的那位绅士证实是小偷。
In the dark street，there wasn’t  single person to whom she could turn for help.在漆黑的大街上没有一个人能为她提供帮助。
(2)当复合介词短语＋which引导定语从句时，这种定语从句常与先行词用逗号隔开，从句用倒装语序。
He lived in a big house，in front of which stood a big tall tree.
他住在一所大房子里，房前有一棵大树。
(3)介词＋which/who＋不定式结构。
The poor man has no house in which to live.
那个可怜的人没有房子住。
(4)of＋which/whom表示所属关系。(表所属关系也可用whose)
Recently I bought an ancient vase，the price of which (＝whos e price) was very reasonable.
最近我买了个古代的花瓶，它的价钱很合理。
关系代词as引导的定语从句
关系代词as既可以引导限制性定语从句，也可以引导非限制性定语从句，as在从句中作主语、宾语或表语。
引导限制性定语从句常用于下列句式：
其中关系代词as在从句中担当主语、宾语或表语。
We have found such materials as are used in their factory.
我们已经找到了像他们工厂里用的那种材料。(as作主语)
These houses are sold at such a low price as people expected.(as作宾语)这些房子以人们期望的低价出售。
He is not the same man as he was.
他和过去不同了。(as作表语)
注意：(1)such...as...(定语从句)像…… 那样
such...that...(状语从句)如此……以至于……
This is such an easy question as I can answer.
(定语从句)这是一个我能回答的简单问题。
This is such an easy question that I can answer it.
(状语从句)这是个简单的问题，我能回答。
(2)the same...as...表示相似的东西
the same...th at...表示同一人或物
This is the same knife as I lost.这把小刀和我丢的那把一样。
This is the same knife that I lost.这把小刀就是我丢的那一把。
关系代词as，which的区别
(1)as引导的非限制性定语从句，既可在主句前，又可在主句后，有时还可插入主句中，而which引导的非限制性定语从句只能置于主句之后。相同的是两者都可替代主句的整个内容，而不是主句中的某一个词。
The weather turned out to be very good，which was more than we could expect.
(2)当非限制性定语从句放在主句前面时，只能用as。
As is known to everybody，the moon travels round the earth once every month.
＝The moon travels round the earth once every month，as/which is known to everybody.
＝It is known to everybody that the moon travels round the earth once every month.
＝What is known to everybody is that the moon travels round the earth once every month.
后两句属名词性从句范畴。
(3)as意为“正如……”，后面的谓语动词多是see，know，expect，say，mention，report，announce等；which意为“这一点”。
As is known to all，Edis on invented the telephone.
＝Edison invented the telephone，as is known to all.
使用定语从句应注意的几个问题
(1)当先行词是way，意为“方式，方法”，在从句中作状语，则引导定语从句的关 系词有以下三种：
我不喜欢他说话的方式。
(2)注意区别先行词和引导词。
①Is this＋名词＋the one ＋that从句
②Is this the＋名词＋that从句
(3)当先行词是表示时间的名词时，应注意引导词在定语从句中的成分。
Do you still remember the days that/which we spent in Qingdao？你还记得我们一起在青岛度过的日子吗？
Do you still remember the days when we spent the summer holidays in Qingdao?
你还记得我们在青岛过暑假的日子吗？
(4)当先行词为case，point，position，situation等词且关系词在从句中作状语时，常用where引导定语从句。
They have reached the point where they have to separate with each other.他们已经到了必须彼此分手的地步。
定语从句中的谓语动词与先行词保持一致
当引导定语从句的关系代词在从句中作主语时，那么定语从句中的谓语动词的数的形式应与先行词保持一致。
(1)one of＋复数名词＋关系代词＋复数动词
He is one of the students who pass the exam.
(2)the only one of＋复数名词＋关系代词＋单数动词
He is the only one of the students who passes the exam.
他是唯一通过考试的学生。
(3)其他情况
I，who am your teacher，will try my best to help you.
我，你的老师，将尽力帮你。
Have you heard of the persons and things that are being talked about？你听说过正在被谈论的这些人和事吗？
