副詞where在非限制性定語從句中作地點狀語,指代主句中表示地點的詞語。 如:They went to London,where they lived for six months.

引導詞
即“引導定語從句的關係詞”
①引導非限定性定語從句的關係代詞:as,which,who
②引導非限定性定語從句的關係副詞主要有:when,where。
注意
不能用that作為關係代詞的兩種情況:
①非限定性定語從句
②介詞+關係代詞
區別
1、as引導的定語從句可以放在句首、句中和句尾,which引導的定語從句可置於句中或句尾。
2、關係代詞as在限定性定語從句中後跟“be動詞+過去分詞”的被動語態時,be動詞可省略。
3、 as有時也可用作關係代詞 。若as在從句中作主語,其引導的句子可以放在句首或句中。但which引導的非限制性定語從句只能放句中。
4、as有正如…一樣、按照、正像、因為的意思,所以常用於肯定句,而which則用於肯定,否定都可以。
5、在固定結構中使用as 例如:the same … as 、as … as。
例句:
1 Dorothy was always speaking highly of her role in the play, which , of course, made the others unhappy.(從句部分的意思為:這當然使別人不高興;而不能譯為正如使別人不高興。故用which。)
2 Chongqing is not the same city as we have seen in other places.
重慶和我們在其它地方看過的城市不一樣。
易錯點
1. 引導限制性定語從句時,關係代詞which可以與that互換;但引導非限制性定語從句時,只能用which。
例1.She heard a terrible noise, ______ frightened her.
A. that B. which C. what D. who
例2.She heard a terrible noise ______ frightened her.
A. that B. / C. what D. who
解析: 例1意為:“她聽到一個可怕的聲音,這使她感到恐懼。”that不能用於引導非限制性定語從句,故選B。例2意為:“她聽到了一個使她恐懼的可怕聲音。”引導修飾noise的限制性定語從句可以用which或that來引導,故選A。
2. 先行詞為reason時,限制性定語可以用why或for which來引導;非限制性定語從句則只能用for which來引導。
例3.I had told them the reason, ______ I didn’t attend the meeting.
A. for which B. at which C. for whom D. why
例4I had told them the reason ______ I didn’t attend the meeting.
A. when B. which C. why D. for that
解析: 例3意為:“我早已把理由告訴了他們,於是我沒有出席會議。”先行詞為reason時,非限制性定語從句套用for which引導,故選A。例4意為:“我已經把沒有出席會議的原因告訴了他們。”the reason why...是常見搭配,答案為C。
3. 引導限制性定語從句的關係代詞在從句中擔任賓語時可以被省略;但引導非限制性定語從句的關係代詞即使作賓語也不能省略。
例5.He was eager to go to the hospital to see his stepmother,______ he loved and respected as his own mother.
A. as B. which C. / D. whom
解析: 本句意為:“他急於去醫院看望他的繼母,他像對待親生母親一樣孝敬她。”關係代詞whom引導非限制性定語從句並作賓語,不能被省略,故選D。
4.引導限制性定語從句時並作從句賓語的關係代詞whom可以用who來代替;但在非限制性定語從句中,whom就不能用who替換。
例6. Do you know Tom, _____ we talked about?
A. which B. that C. whom D. who
例7.The American journalist ______ the announcer mentioned in the news broadcast is said to have been killed by the gangsters. Which of the following is wrong?
A. who B. whom C. whose D. /
解析: 例6意為:“你認識湯姆嗎? 我們談到過他。”應選C。例7意為:“播音員在新聞廣播中提到的那位美國記者據說已遭歹徒殺害。下列哪一項是錯誤的?”關係代詞作mentioned的賓語且指人時,可用who/whom/that,在限制性定語從句中可省略,故C是錯的。
5.當非限制性定語從句修飾整個主句時,其關係代詞可以用as 和which,但位於舉句首不能用which,只能用as。此時非限制性定語從句可置於主句之前、之後或之中。
例8______ I expected, he didn’t believe me.
A. Which B. As C. That D. When
解析: 本句意為:“正如我所預料的那樣,他不相信我的話。”非限制性定語從句修飾整個主句,套用as引導,故答案為B。
例9.Mary was late for school,______ often happened.
A. as B. for which C. that D. why
解析: 本句意為:“瑪麗上學遲到了,這是常有的事。”根據句意,關係代詞as引導的非限制性定語從句修飾前面的主句,其位置非常靈活,故答案為A。
6. 由“介詞+關係代詞”引導非限制性定語從句,關係代詞指代整個主句時,不能用as,只能用which,因為有介詞關係。
例10.He bought the car for more than $20,000,______ his father was angry.
A. about that B. with as C. when D. with which
解析: 本句意為:“他花兩萬多美元買了這輛車,他父親對此很生氣。”which位於介詞with的後面,指代前面的主句,故答案為D。
注意事項
1. which引導的非限定性定語從句是用來說明前面整個句子的情況或主句的某一部分。
2. as有時也可用作關係代詞 。as引導非限制性定語從句,若as在從句中作主語,其引導的句子可以放在句首,也可以放在句中。但which引導的非限制性定語從句只能放句中。
例句:
As is reported in the newspaper ,some artistic treasures(藝術珍品) will be on show at the exhibition (展覽品)on the weekend.
3. 在非限定性定語從句中,關係詞不能用that,和those。
從句區別

非限定性定語從句:先行詞不可以用that引導。
3.限定性定語從句:引導詞有時可以省略。

4.限定性定語從句:主句與從句不需要用逗號隔開。
非限定性定語從句:主句與從句需要用逗號隔開。

非限定性定語從句:從句既可以修飾先行詞,也可以修飾整個句子或句子的一部分。
6.限定性定語從句:不能修飾一個事件。

功能用途
限定性定語從句與主句的關係很緊湊,對其先行詞起限定、修飾的作用。如果將其去掉,會影響句子意思的完整性;有時甚至於引起費解、誤解。例如:
1.Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nations in which they are located .
為了加速他們各自所在國家的經濟發展,熱帶雨林作為有價值的原木和其他資源正為人們所砍伐。
2.Ocean currents affect the climates of the lands near which they flow.
洋流影響其流經的附近地區的氣候。
3.They explained the reason to us why they had hated us before.
他們向我們解釋為什麼他們不喜歡我們的原因。
非限定性定語從句在形式上就與主句很鬆散,它與主句之間有一個逗點","隔開;它對其先行詞沒有限定、修飾的作用,只起補充、說明的作用。有時也用它來對全句或句中某個成分進行補充、說明。即使將其去掉,也不會影響句子意思。由於上述原因,非限定性定語從句在表達意思方面也有別於限定性定語從句。另外,非限定性定語從句在中文譯文裡,我們往往將其作為一個分句處理,而不把它作定語翻譯。 例如:
Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy .
更早之前,巴比倫人曾試圖繪製世界地圖,但是他們把它繪製成平盤狀而不是托勒密所採用的球體狀。
(此句中,非限定性定語從句是對先行詞a sphere進行補充、說明。)
The combination of satellites, which transmit information , computers , which store information , and television , which displays information , will change every home into an education and entertainment center .
衛星能傳輸信息,計算機能儲存信息,電視能顯示信息,把這些手段結合起來可以使每個家庭都成為教育娛樂的中心。
(此句中,三個非限定性定語從句分別對三個先行詞:satellites ,computers和television進行補充、說明。如果去掉這三個非限定性定語從句,那么句子可簡化為:The combination of satellites , computers and television will change every home into an education and entertainment center .)
The sun heats the earth , which makes it possible for plants to grow .
太陽給予大地熱,這就使植物的生長成為可能。
(此句中,非限定性定語從句是對全句進行補充、說明,將全句表達的意思看成"一件事情)。
The old man has a son , who is in the army .
那位老人有一個兒子,他在部隊工作。
(此句中,非限定性定語從句是對先行詞son進行補充、說明。但本句所傳達的信息是:"這位老人只有一個兒子" 。如果將此句改寫成限定性定語從句:"The old man has a son who is in the army . "那位老人有一個在部隊工作的兒子。那么,限定性定語從句就要對先行詞son進行限定、修飾。這樣一來,句子所傳達的信息就變成了:"這位老人有一個兒子在部隊工作",也就是說可能老人還有其他的兒子在乾別的工作)
