2015年職稱英語(yǔ)考試備戰(zhàn)已經(jīng)開(kāi)始了，這是小編整理的一些常見(jiàn)的語(yǔ)法，希望對(duì)您能有所幫助。開(kāi)心生活，快樂(lè)學(xué)習(xí)。每天進(jìn)步一點(diǎn)，積累下來(lái)便是巨大的進(jìn)步。

    If it were not for ……

    結(jié)構(gòu)︰if it were not for＋名詞/子句，主詞＋would/should等＋原形動(dòng)詞…

    說(shuō)明︰此句型意為“若非（有）…”。此類句構(gòu)專門用于表示與現(xiàn)在事實(shí)相反的。亦可用“but for＋”或“without＋”代替。were可以提前，省略if。

    If it were not for his presence,I would punish you.要不是他在場(chǎng)，我會(huì)處罰你的。

    But for your advice,I should have failed.要不是你的忠告，我會(huì)失敗的。

    But for music(=Were it not for music),life would be dull.要不是音樂(lè)，人生會(huì)很無(wú)聊。

    If it were not for oxygen and nitrogen in the air,no man could live on the earth.

    大氣中如果沒(méi)有氧和氮，人就無(wú)法生存于地球了。
