look up the dictionary
汉语中的“查字典”,说成英语通常是 look up sth in a dictionary 或 consult [refer to] a dicti件句,而是利用其他手段来示意存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常用来表示含蓄虚拟条件的手段有:
(1)介词或介词(短语)。如but for,but that,without,in case of, under more favorable condition等。
(2)连词。如so that, unless, in case, supposing,lest, provided(如果……),for fear that(生怕),in orderthat, on condition that, if only(要是……就好了)等。
留意:lest, for fear that和in case引起的从句中谓语动词多用should+动词原形,但也可以不用虚拟语气,而用动词的陈述语气形式。例如:The foreign teacher spokeslowly in case we misunderstood him这位外籍教师说得很慢以免我们误会。
(3)通过上下文及内在含义,句中往往有but,otherwise, unfortunately等类似转折词。
without, but. but for, otherwise引起的短语或(句子)常暗含着含蓄条件。例如:
①Without you,1 would never know him
②But for your oooperation, we wouldnt have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!
