省略句知識點總結：省略在虛擬條件句型中的應用
【導語】英語語法讓很多學生都頭疼，因為復雜難懂的句式和詞組有時難以記憶。英語網為大家整理了英語語法大全，希望對同學們的英語語法學習有所幫助。更多內容盡在英語網。
一、省略連詞if
有時可將條件從句的連詞if省略，但此時應用倒裝句型，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, 那我就留下。
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，我們就準時到達了。
注：
① 若條件從句為否定句，否定詞not應置于主語之后，而不能與were, should, had 等縮略成werent, shouldnt, hadnt而置于句首。
② 有時省略if后提前的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，通常可將主語和動詞be省略。如：
If repaired earlier, the tractor would not have broken down.
要是早點兒修一下，拖拉機就不會拋錨了。(=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，即省略條件從句后，所剩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.)
