补充2.省略连词if的虚拟条件句中(易错点☆☆☆)

如果把连接条件从句的连词if省略，必须将从句的谓语部分的助动词had,情态动词should或系动词were等移至主语之前，构成倒装语序。☆谐音记忆：(还had属should我were)

①Had he known my address(=If____________________________), he would have visited me earlier.

②Should I meet Jay Zhou someday(=If________________________), I might tell him that I like him.

③Were I you(=If _______________________), I would get on well with my teachers andclassmates.

补充3.在as if, as though方式状语从句中（基础知识☆☆☆）

在as if/though后的方式状语从句中，表示某种情况与现在的事实相反, 谓语动词用过去式;表示即将发生的情况“用情态动词+动词原形”;表示某种的情况有过去的事实相反, 谓语动词用过去完成时。

①The coachalways treats the players as if he ________(be) their own father.

②Her head felt as if it____(burst).

③Gary was behaving asthough nothing _______(happen).

有时：as if/though从句描述的是事实，则用陈述语气。

It looks asif it is going to rain.

It sounds asthough she has been really ill.

补充4 如果是真实事实，那么用正常的陈述语气。

例如 It looks as if it is going to rain.(确实要下雨)。

5.If it were not for the fact that she sing, I would invite her to the party. (06福建)

A. couldn’t B. shouldn’t C. can’t D. might not
