☆句型詮釋☆
1. The reason why he could not go there was that his grades were too low. 他沒能上電影學(xué)院是因?yàn)樗姆謹(jǐn)?shù)太低了。
該句巾的why引導(dǎo)一個(gè)定語從句，而that引導(dǎo)表語從句。
1. 句中that引導(dǎo)的表語從句說明主語reason的具體內(nèi)容，往往被看作是固定句型：The reason is / was that clause. 當(dāng)主語是reason / cause時(shí)，一般不能用because或why引導(dǎo)表語從句，以免造成語意重復(fù)。當(dāng)主語是This / That時(shí)，可以由because / why引導(dǎo)表語從句。例如：One reason is that people traveled to America from all European countries.
【考例】(NMET 1999)
-- I drove to Zhuhai for the air show last week.
-- Is that ____ you had a few days off?
A. why B. when C. what D. where
[考查目標(biāo)] 表語從句。
[答案與解析]A 句子的意思是“那就是你請了幾天假的原因嗎?”因此可知答案為why。
2. why在句中是關(guān)系副詞，引導(dǎo)定語從句，修飾先行詞reason，同時(shí)它在定語從句中作狀語，此時(shí)why = for which，但要注意：關(guān)系詞在定語從句中作主語或賓語時(shí)，要用關(guān)系代詞that或which。
【考例】Is this the reason ____ at the meeting for his carelessness in his work?
A. he explained B. what he explained
C. how he explained D. why he explained
[考查目標(biāo)]定語從句。
[答案與解析]A what，how不能引導(dǎo)定語從句，排除B、C兩項(xiàng);the reason在定語從句中作explained的賓語，可填that / which，或者也可以省略。
2. Many people who saw the film were afraid to swim in the sea when they remembered the scenes in which people were eaten by the shark. 好多看過這個(gè)片子的人一想起片中鯊魚食人的場面.就不敢下海游泳了。
該句是一個(gè)復(fù)雜長句，從when到句子末尾是狀語從句，在從句中包含一個(gè)由which引導(dǎo)的定語從句，修飾先行詞scenes; 在前面的主句里面。包含一個(gè)由who引導(dǎo)的定語從句，修飾先行詞people。例如：Those who want to go camping next Sunday sign your name here before class is over.
定語從句關(guān)系詞的選擇，要遵循“瞻前顧后”的原則，所謂“瞻前”即看前面的先行詞指人還是指物;“顧后”即后面的定語從句，看關(guān)系詞在定語從句中作什么成分。例如：This is the factory where he works. (狀語) / This is the factory (that / which) he visited. (賓語)
