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.

　?、赥hat she was chosen made us very happy.

　　③That he will come is certain.

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

　　⑤That 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：

　?、買(mǎi)t was obvious that the driver could not control his car.

　?、贗t 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.

　?、軮t isn't surprising (that) he should have married
