1.that引導主語從句
that引導主語從句時不同于其他的連詞,既無詞義也不作成分,只起單純的連接作用,且通常不可以省。為了強調(diào)that引導的主語從句而置之于句首時,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.

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
