4、ld teach. There was only a road that led out of the mountains.

(形容词作定语
7、)Harry Porter is a boy who has magic power. (定语从句)This is an old computer. It works much slower. 这是一台老式电脑。它工作起来速度很慢。 (这是两个简单句,It代替an old computer)This is an old computer which/that works much slower. 这是一台工作起来比较慢的老式电脑(这是一个主从复合句,which/that代替an old computer,引导定语从句)普通代词只起替代作用,如在上例中It替代an old computer. 而
8、关系代词除可以起替代作用之外还可以引导定语从句。2. 关系代词的用法(1)关系代词有who, whom, whose, which, that。它们的具体使用情况如下表所示:关系词先行词在从句中充当的成分备注关系代词who人主语、宾语whom, which和that在从句中作宾语时,常可以省略,但介词提前时后面的关系代词不能省略,也不可以用that和whowhom人宾语which物主语、宾语that人或物主语、宾语、表语whose人或物定语whosen.then.of which/whomof which/whomthen.(先行词指人时用whom,指物时用which)(2)在定语从句中,使用
9、关系代词时我们应该考虑两点:一是先行词是“人”还是“物”;二是关系代词在定语从句中充当什么成分。He is a man who/that means what he says.他是一个说话算话的人。(先行词指人,关系代词who/that引导定语从句,并在从句中作主语)Is there anyone in your class whose father is a teacher?你们班有谁的父亲是老师?(先行词指人,关系代词whose引导定语从句,并在定语从句中作定语)To be frank, I dont like the movie (which/that) you recommended
10、to me yesterday.说实话,我不喜欢你昨天推荐给我的那部影片。(先行词指物,关系代词which/that引导定语从句,并在从句中作宾语,可省略)II. 关系代词用that而不用which的情况1. 当先行词是all, much, anything, nothing, little, none等不定代词时She told me everything that she knew.她把她所知道的一切都告诉了我。2. 先行词既有人又有物时I can remember well the persons and some pictures that I saw in the room.我能清楚
11、地记得我在那个房间所见到的人和一些照片。3. 先行词为序数词或被序数词修饰时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。4. 先行词为形容词最高级或被形容词最高级修饰时This is the best film that I have ever seen.这是我看过的最好的电影。5. 先行词为the last, the only, the very, the same等或被这些词修饰时Mr. Smith is the only foreigner that he k
12、nows.史密斯先生是他唯一认识的外国人。6. 主句是以who或which开头的特殊疑问句时Which is the true story that he told us?他给我们讲的哪一个故事是真实的?7. 当先行词在主句中作表语或关系代词在从句中作表语时Tom isnt the man that he used to be.汤姆不再是过去的样子了。III. 关系代词用which而不用that的情况1. 先行词为that时Whats that which is under the desk?桌子底下的那个东西是什么?Its a football.那是一个足球。2. 关系代词前有介词时This
13、 is the room in which he lives.这是他住的房间。3. 引导非限制性定语从句时Tom came back, which made us happy.汤姆回来了,这使我们很高兴。关系副词(时间/地点/原因)的用法A. where指地点,充当地点状语;此时可用in which/ on which/ at which/ to which 等取代This is the place. We spent our childhood in that place. 替换:This is the place (which / that) we spend our childhood
