2016職稱英語衛(wèi)生類句型備考:
Unless ...
結(jié)構(gòu)︰Unless+子句,主要子句
說明︰此句型意為“除非…”。unless 引導(dǎo)一個否定假設(shè)句,相當于 if ... not ...,有時可以互換使用?傮w上看,unless 的語氣強于 if ... not ...,而且有時較為常用,例如在最后通牒中。
Unless you change your mind (=If you don't change you mind),I won't be able to help you.
除非你改變你的想法,否則我不能幫助你。
Unless the management improves their offer,there'll be a strike.
除非資方做出進一步的建議,否則將舉行罷工。
