5、6.when提示:引导词用关系代词还是用关系副词关键要看他们在从句中作什么成份而定。或者说，假如把先行词放到从句中是作主语、宾语还是状语而定。实例分析:1.Is this the museum _ we held the exhibition? A. where B. that C. on which D. the one2.Is this museum _ you visited a few days ago?A. where B. that C. on which D. the one提示：先把以上句子变为肯定句例1变为肯定句： This is the museum _ we held t

6、he exhibition.例2变为肯定句： This museum is _ you visited a few days ago.答案：1.where 2.the one(that /which)(小结)解题步骤：通读全句，首先判断是什么句型； 题干句如果是疑问句式，将其转化为陈述句式； 找出从句部分及先行词； 分析从句的句子结构，判断从句中所缺的成分，缺主语、宾语或定语用关系代词； 不缺主语、宾语或定语时选用关系副词做状语。考点二:关系代词which 和that的区别在定语从句中, 当先行词指物时, 下列情况的关系词宜用that而不用which:1.先行词被形容词最高级；序数词；the

7、only, the very, the right ,the same 修饰时。This is the only book that I bought today.2.先行词为all, everything, something, anything, nothing, none等不定代词时。Is this all that is left？3. 先行词中既有人又有物时。Look at the man and his horse that are walking up the street.4.先行词在从句中作表语。Mary is no longer the girl that she used

8、 to be.5.当主句中含有疑问词which或who时,为避免重复，常用that 代替who 或which。Which are the books that you bought for me?6.主句以there be 开头时There is little that I can do to make up for the lost time.在定语从句中, 当先行词指物时,只能用which而不能用that 的情况：1.在介词提前的定语从句中，关系代词只能用which。This is the house in which Lu Xun used to live.2.Which 可引导非限制性

9、定语从句，that则不能。She failed the exam, which made her parents vary angry.考点三：as与which引导的定语从句二者都可以引导非限制定语从句，指代从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.在下列情况下一般只能用as：(1) as 放在句首，而which不能。(2) as 本身有“正如；正像”之意，而which 没有；此时as常和 know, see, expect, announce, suggest, hope, believe 等连用。e.g. As

10、 we all know, the earth is round.由as构成的常用短语As everybody knows/As is known to everybodyAs we can seeAs is often the caseAs is reported in the newspaper(3) 当先行词被the same, such修饰时，定语从句需用as引导e.g. Such books as you tell me are interesting. I have the same plan as you.the same as(指同类的东西) the same that(指同一

12、及转换形式1. whose引导定语从句，其后应紧跟名词，构成名词短语。其先行词不仅可以指人，还可以指物。Do you know the woman whose husband is a doctor?This is a book whose cover is green.2. Whose引导的从句可转换为“ of +关系代词”型，如：即whose+名词=the +n + of which/whom =of which/whom + the + n.He lives in the room whose window faces south.= He lives in the room, the

13、window of which faces south.= He lives in the room, of which the window faces south.考点五：介词+关系代词提醒: 介词关系代词(whom/which)引导的定语从句, 关键是判断介词的选择.The teacher for whom you are waiting is coming.This is the room in which Lu Xun used to live.方法一:根据从句中动词的习惯搭配He came to a farm, on which he finally settled.The spe

14、ed at which light travels is 3000,000 km per second.方法二:根据先行词的习惯搭配The colorless gas is called oxygen, in which fires burn much better.The colorless gas is called oxygen, without which we could not live.方法三:根据句子所需要的意思 注意：关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。此时关系代词只能用which 或 whom; 不可用that 或who 代替非限制性定语从句

15、中，要表示先行词的一部分时，可用“名词/数词/代词 + of which/whom”的结构，如：There are 50 students in our class, two-thirds of whom have been to Beijing.实例分析：1(2004湖北卷) There are two buildings, _ stands nearly a hundred feet high. A. the larger B. the larger of them C. the larger one that D. the larger of which解析：答案为D。the large

18、who/whom you spoke to was a scientist.The city that/which she lives in is far away.The man to who /whom you spoke was a scientist.The city in that/which she lives is far away.提醒who、that 不能用与介词之后Is this the watch that you are looking for?The old man whom I am looking after is better .注意：含有介词的短语动词一般不拆

19、开，介词仍放在短语动词的后面，不能提前。如：look for, look after, take care of 等。练习: 介词+关系代词的使用1. Do you like the book she paid $10?2. He built a telescope he could study the skies.3.
