5、进行。在英语中,我们可以用unless表达这个意思,相当于if not。以这个句子为例:The concert will be held as schedule unless there is a typhoon. = the concert will be held as schedule if there is not a typhoonShe will keep on singing unless she is told to stop. 她会一直唱下去,除非有人叫她停止.= she will keep on singing if she is not told
6、to stop也可以用or(否则) 来做同义句转换Unless you listen carefully, you won’t know the answer. = if you don’t listen carefully, you won’t know the answer. = you should listen carefully, or you won’t know the answer.g:IwillnotgounlessIhearfromhim.=IwillnotgoifIdonothearfromhim.如果他不通知我,我就不去.You'llbelate
