一、省略連詞if 有時可將條件從句的連詞if省略,但此時應(yīng)用倒裝句型,即將從句中的were, should, had 等提到句首。如: Were I you, I would stay. 倘若我是你, 那我就畱下。 Should I be free tomorrow, I will come. 萬一我明天有空,我會來。 Had it not been for the bad weather we would have arrived in time. 若不是天氣壞,我們就準(zhǔn)時到達(dá)了。 注:① 若條件從句爲(wèi)否定句,否定詞not應(yīng)置於主語之後,而不能與were, should, had 等縮略成weren't, shouldn't, hadn't而置於句首。 ② 有時省略if後提前的had不是助動詞。如: Had I time, I would come. 假若我有時間,我會來的。(=If I had time…) 二、省略從主語和動詞be 若主從句主語一致,且謂語部分包含有動詞be,通??蓪⒅髡Z和動詞be省略。如: If repaired earlier, the tractor would not have broken down. 要是早點(diǎn)兒脩一下,拖拉機(jī)就不會拋錨了。(=If it had been repaired earlier…) 三、省略“it+be” If necessary, I would send more farm-hands to help you. 如果需要的話我會派更多的民工去你。 四、省略整個條件從句 這樣的省略通常需要借助一定的上下文,即省略條件從句後,所賸下的主句的意思在一定的上下文中意思是清楚的。如: I might see her personally. It would be better. 我可以親自去看她,這樣好一些。(=…If I saw her personally, it would be better.)
