主語從句作主語時，謂語動詞一般用單數(shù)形式。Conclusion:主語從句一.以that引導(dǎo)的主語從句that是純連詞，在從句中不充當(dāng)任何成分，不翻譯，置于句首不能省略；這類從句大多情況要置于句子后面，而用it作形式主語。常見的句型有：1.It+be+形容詞（+for

sb./ofsb.）+that從句(obvious,true,necessary,etc.此類adj.常與介詞for連用）（kind，friendly，generous,etc.此類adj.常與介詞of連用)Itisnecessary

that

heshouldbeherebytheweekend.周末之前，他應(yīng)該到這里是必要的。

1）常與其后的名詞作表語一致2）根據(jù)句子的語境而定。?主語從句需注意的問題2.主語從句中用陳述語序Whatyouleft____(be)onlyseveraloldbooks.Whatyousaid____
