47   假設語氣的倒裝句

在較文學性文章中，if開頭的假設語氣中，若將had, were, should, did等助動詞置於句首，可將連接詞If省略，成為倒裝句。請仔細看下面例句：

Be +主詞

1. If it were necessary, I might go with you. 如果需要的話，我可以跟你一起去。
   = Were it necessary, I might go with you.
2. If I were not here, I wouldn’t be happy.
   = Were I not here, I wouldn’t be happy.

Had +主詞

1. If they had listened to their parents, they wouldn’t have done such a terrible thing.
   = Had they listened to their parents, they wouldn’t have done such a terrible thing.
2. Had we not missed the plane, we would have been killed in the crash.
   = If we hadn’t missed the plane, we would have been killed in the crash.

Should/ Could/ Might/ Would +主詞

1. If I should have time, I would call on her.要是我有時間就去看她。
   = Should I have time, I would call on her.
2. If Tom should not come, we should do it by ourselves.
   = Should Tom not come, we should still do it. 萬一Tom沒來，我們仍然要進行。
3. If he could get another chance, he would succeed.
   = Could he get another chance, he would succeed.
4. If I might see Dad again, I would die with happy tears.
   = Might I see Dad again, I would die with happy tears.
5. If she would rent this apartment, it could be 20% off.
   = Would she rent this apartment, it could be 20% off.

非必要不一定要這樣表達想法，但需要知道別人用這樣的句子是要表達甚麼。
