24、erything, little, none等不定代詞，關系代詞一般只用that，不用which。例如： All the people that are present burst into tears. (2) 如果先等詞被形容詞最高級以及first, last, any, only, few, mush, no, some, very等詞修飾，關系代詞常用that,不用which, who，或whom。例如： (3) 非限制性定語從句中，不能用關系代詞that,作賓語用的關系代詞也不能省略。例如： There are about seven million people taking pa

25、rt in the election, most of whom、are well educated. (4) which還有一種特殊用法，它可以引導從句修飾前面的整個主句，代替主句所表示的整體概念或部分概念。在這種從句中，which可以作主語，也可以作賓語或表語，多數情況下意思是與and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy. (5) that可指人或物，在從句中作表語，（指人作主語時多用who）僅用于限制性定語從句中。 (6) which可作表語，既可指人，以

26、可指物。指人時，一般指從事某種職業或是有種特征品性或才能的人。Which引導的定語從句可以限制性的，也可以是非限制性的。 (7) 如果作先作詞的集體名詞著眼于集體的整體，關系代詞用which;若是指集體中的各個成員，則用who。 (8) 先行詞有兩個，一個指人，一個指物，關系代詞應該用that。例如： The boy and the dog that are in the picture are very lovely. (9) 如果先行詞是anyone, anybody, everyone, everybody, someone, somebody,關系代詞應該用 who 或whom，不用

27、which。例如： Is there anyone here who will go with you?3“介詞關系代詞“是一個普遍使用的結構 (1) “介詞關系代詞“可以引導限制性定語從句，也可以引導非限制性定語從句。“介詞關系代詞“結構中的介詞可以是 in, on, about, from, for, with, to at, of, without 等，關系代詞只可用whom或 which,不可用 that 。 (2) from where為“介詞關系副詞“結構，但也可以引導定語從句。例如： We stood at the top of the hill, from where we c

28、an see the town. (3) 像listen to, look at, depend on, pay attention to, take care of等固定短語動詞，在定語從句中一般不宜將介詞與動詞分開。例如： This is the boy whom she has taken care of.二關系副詞引導的定語從句 1關系副詞也可以引導定語從句 關系副詞在從句中分別表示時間地點或原因。關系副詞when在從句中充當時間狀語，where 充當地點狀語，why充當原因狀語。 2. that可引導定語從句表示時間地點或原因 That有時可以代替關系副詞 when, where 或

29、者why引導定語從句表示時間地點或原因，在 that引導的這種定語從句中，that也可以省去。三限制性定語從句與非限制性定語從句 1二者差異比較 限制定語從句緊跟先行詞，同先行詞這間一般不加逗號，僅修飾先行詞，可以由關系代詞關系副詞或that來引導。非限制性定語從句僅作補充或說明，用逗號與主句隔開，既可修飾先行詞，又可修飾整個主句，不可用that引導。 2關系代詞和關系副詞的選擇依據 (1) 弄清代替先行詞的關系詞在從句中作什么成分,作狀語的應選用關系副詞，作主語賓語或表語的可選用關系代詞。 3. 先行詞與定語從句隔離 定語從句一般緊跟在先行詞之后，但定語從句與先行詞之間有時也會插入別的成分，

30、構成先行詞與定語從句的隔離。例如： 1) This is the article written by him that Is poke to you about. 2) He was the only person in this country who was invited四As在定語從句中的用法 1. 引導限制性定語從句和非限制性定語從句 （1）as多與such 或the same連用，可以代替先行詞是人或物的名詞。 （2）as 也可單獨使用，引導非限制性定語從句，作用相當于which。例如：The elephants nose is like a snake, as anybody

31、can see. 3）the same that與 the same as在意思上是不同的。 2As引導的非限制性定語從句的位置 as引導的非限制性定語從句位置較靈活，可以位于主句前面中間或后面，一般用逗號與主句隔開，但which所引導的非限制性定語從句只能放在主句之后。例如： (1) As is expected, the England team won the football match. (2) The earth runs around the sun, as is known by everyone.眾所周知, 定語從句可以分為限制性定語從句和非限制性定語從句。下面結合考例談談學

32、習運用非限制性定語從句時應注意的幾個問題： 一、that不能用來引導非限制性定語從句。如： 【考例一】She heard the terrible noise, _brought her heart into her mouth. A. it B. which C. this D. that 【解析】選B。后半句為非限制性定語從句，盡管先行詞noise屬于事物，也不能用that而要用which來引導。which指代noise，在從句中作主語。 二、除which外，還可用when，where，whose，whom等引導非限制性定語從句，且各自的用法及差異與它們用在限制性定語從句時相同。如： Ne

33、xt month, when youll spend your summer holidays in your hometown, is approaching. 下個月即將來臨，屆時你們將在家鄉度暑假。(關系副詞when指代表示時間的名詞next month，并作從句的狀語。) She is going to live in Macao, where she has some close friends. 她要到澳門去居住，在那里她有幾個密友。 (關系副詞where指代表示地點的名詞Macao，并在從句中作狀語。) 【考例二】Recently I bought an ancient Chin

34、ese vase, _was very reasonable. A. which price B. the price of which C. its price D. the price of whose 【解析】選B。whose在從句中作表示所屬關系的定語，既可指代人，也可指代物。指物時，常可轉換為of which；指人時常可轉換為of whom。 【考例三】 In the office I never seem to have time until after 5:30 pm,_many people have gone home. A. whose time B. that C. on

35、 which D. by which time 【解析】 先行詞5:30 pm與time之間是一種同位關系，可用which來作定語替代。從句中的完成狀態，常與by短語連用。故選D。 三、在非限制性定語從句中作賓語的關系代詞不能省略。如： He was eager to go to the hospital to see his stepmother, whom he loved as his own mother. 他迫切地想到醫院去看望他的繼母，他把繼母當自己的親媽媽一樣愛戴。 四、非限制性定語從句的關系代詞which，既可以指代前面的先行詞，也可以指代前面整句的含義。如： 【考例四】 Dorothy was always speaking highly of her role in the play, of co
