高考英語(yǔ)一輪復(fù)習(xí)（語(yǔ)法）—名詞性從句 高考英語(yǔ)一輪復(fù)習(xí)（語(yǔ)法）—名詞性從句

　　在復(fù)合句中充當(dāng)主語(yǔ)的從句。

　　1.that引導(dǎo)主語(yǔ)從句

　　that引導(dǎo)主語(yǔ)從句時(shí)不同于其他的連詞，既無(wú)詞義也不作成分，只起單純的連接作用，且通常不可以省。為了強(qiáng)調(diào)that引導(dǎo)的主語(yǔ)從句而置之于句首時(shí)，that不可省。

　?、賂hat the driver could not control his car was obvious.

　　②That she was chosen made us very happy.

　?、跿hat he will come is certain.

　?、躎hat he would take the risk is true.

　?、軹hat he should have married her isn't surprising.

　　★通常，that引導(dǎo)主語(yǔ)從句時(shí)用it做形式主語(yǔ)，把從句置于句尾，此時(shí)that有時(shí)可省。例如：

　　①I(mǎi)t was obvious that the driver could not control his car.

　　②It made us very happy that she was chosen.

　?、跧t is certain that he will come.

　?、躀t is true that he would take the risk.

　　⑤It isn't surprising (that) he should have married
