TheThreeGorgesDam。

滾滾長江，泱泱中華。毛澤東暢游長江時，揮毫留下了浪漫之作《水調歌頭?游詠》，為我們描繪了“高峽出平湖，神女應無羌，當驚世界殊”的壯美圖畫。而今，葛洲壩上游興建的三峽工程將成為世界上最大的水力發(fā)電站，萬噸巨輪可駛抵重慶，三峽景色將更加絢麗多姿。

1.限制性定語從句對所修飾的詞加以限制,表示"……的人(或東西)",限制性定語從句描述的是主句不可缺少的一部分；非限制性定語從句對所修飾的詞沒有限制詞義的作用,而只是補充說明,通常都有一個逗號把它和句子的其他部分分開,在譯成中文時,這個從句常譯成一個并列句。如:

Heistheman(who/that/whom)you’vebeenexpectingtomeet.他就是你一直想見的那個人。

ThisisMrSmith,whom/whoyou’vebeenexpectingtomeet.這位是史密斯先生,你一直想見的那個人。

Thereare30chairsinthehall,mostofwhicharenew.

3.當先行詞是專有名詞或由物主代詞/指示代詞修飾時,其后的定語從句通常是非限制性的。如:

Mysonfailedagainintheexam,whichmademeveryangry.

注意:

1.關系代詞that和關系副詞why不能引導非限制性定語從句。

2.as或which引導的非限制性定語從句,可以修飾整個主句或主句的一部分。as引導的定語從句還可以放在主句之前,而which引導的非限制性定語從句要放在句末。如:

Ashasbeenannounced,weshallhaveourfinalexamsnextmonth.

Weshallhaveourfinalexamsnextmonth,as/whichhasbeenannounced.

3.as引導定語從句時,意為"正如……那樣",如:

Asweknow,smokingisharmfultoone’shealth.正如我們所知,吸煙有害健康。
