在引導(dǎo)虛擬條件句的時(shí)候，if在什么情況下會(huì)省略呢，一些學(xué)生還是存有疑惑，今天我給大家簡(jiǎn)單說明一下。（這可是高考語法中考核的一項(xiàng)核心內(nèi)容，大家必須掌握的）

如果從句中有were, had, should,可以省略if,用倒裝句式“were, had, should+主語”。如：

If I were at school again, I would study better.

= Were I at school again, I would study better.

If you had come earlier, you would catch the bus.

= Had you come earlier, you would catch the bus.

If it should rain tomorrow, we would not go climbing.

=Should it rain tomorrow, we would not go climbing.

注：若省略的條件句中的謂語動(dòng)詞是否定形式時(shí)，不能用動(dòng)詞的縮略形式。如：

我們可以說：Were it not the expense, I would go abroad now. 但不能說：Weren't it for the expense, I would go abroad now.
