That的具體用法

　　that可以引導(dǎo)名詞性從句、定語(yǔ)從句,其具體用法如下：

　　一、that引導(dǎo)名詞性從句時(shí)(即主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句、同位語(yǔ)從句),在從句中無(wú)具體含義,只起連接作用,而且在從句中也不作任何句子成分.它所引導(dǎo)的從句的句子結(jié)構(gòu)和意義是完整的,而且從句一般是陳述一個(gè)事實(shí).

　　例如:

　�、賂hat she was able to come made us very happy.

　　她能來(lái)使我們很高興.

　�、赥he news that our team has won the match is true.

　　我們隊(duì)贏了這場(chǎng)比賽的消息是真的.

　�、跿he reason he didn't come was that he was ill.

　　他沒(méi)來(lái)的原因是他病了.

　　當(dāng)that引導(dǎo)的主語(yǔ)從句或賓語(yǔ)從句太長(zhǎng)時(shí),常用it作形式主語(yǔ)或賓語(yǔ)而把that從句放在后面.如:

　�、買(mǎi)t is well—known that the earth is round.

　　眾所周知,地球是圓的.

　�、赪e find it necessary that we practise spoken English every day.

　　我們發(fā)現(xiàn)每天練習(xí)英語(yǔ)口語(yǔ)很有必要.

　　注意：

　　that引導(dǎo)的主語(yǔ)從句,表語(yǔ)從句以及同位語(yǔ)中,that不能省略.that引導(dǎo)的賓語(yǔ)從句,一般可以省去that,但在下面情況中不能省略——

　　1.在suggest,order等表示命令、請(qǐng)求、建議等動(dòng)詞后的賓語(yǔ)從句中,不能省;

　　2.由and或but所連接的兩個(gè)引導(dǎo)的賓語(yǔ)從句時(shí),第一個(gè)從句中的`that可以省,第二個(gè)從句中的that不能省;

　　3.that引導(dǎo)的賓語(yǔ)從句,如果從句中還有其他狀語(yǔ)從句,引導(dǎo)賓語(yǔ)從句的that不能省略.

　　Tell him that if he is at home,I'll call to see him.

　　二,that引導(dǎo)定語(yǔ)從句要注意以下幾點(diǎn):

　　1.定語(yǔ)從句中缺主語(yǔ),修飾人時(shí)用who /that,修飾物時(shí)用which /that引導(dǎo).如:

　　Is this the factory which /that makes TV sets

　　The man who /that visited our school is from Australia.

　　2.從句中缺賓語(yǔ),修飾人時(shí)用 who /whom /that或省略引導(dǎo)詞;修飾物時(shí)用which /that或省略引導(dǎo)詞.如:

　　Gone are the days which /that we spent together in the village.

　　He is the man who /whom /that I think to be worthy of our praise.

　　3.用that不用which的七種情況:

　�、傧刃性~前有形容詞最高級(jí)或序數(shù)詞修飾時(shí),用 that不用which引導(dǎo).如:

　　This is the best place that I have ever visited.

　�、谙刃性~為little,much,all,none,few,(the)one,something,everything,nothing,anything等不定代詞時(shí),用that引導(dǎo).如:

　　There is nothing in the world that can frighten him.

　　③先行詞既有指人的名詞又有指物的名詞時(shí),用 that引導(dǎo).如:

　　He told us about the people and the cities that he had visited.

　�、芟刃性~前有any,all,no,few,every,some,little,much,(the)very,(the)only,(the)last等詞修飾時(shí),用 that引導(dǎo).如:

　　This is the very coat that I need.

　�、菹刃性~為which時(shí),為了避免重復(fù),用that引導(dǎo).如:

　　Which is the book that you bought yesterday

　　⑥先行詞在從句中作表語(yǔ)時(shí),常用that引導(dǎo).如:

　　Shanghai is no longer the city that it used to be in the 1930's.

　�、弋�(dāng)主句是There be...句型時(shí),用that引導(dǎo).

　　There are two tickets for the film that are for you two.
