    虚拟语气在一些特殊词中的使用或含蓄条件句
    1.wish后的宾语从句。
    与现在愿望不一致，用主语十过去时，例如：
    I wi。hIwere you.
    与过去愿望不一致，用主语+had+过去分词，例如：Iwish I had visited the White House whenI was in the States与将来愿望不一致，用主语+would (could)+原形。
    2.It's time句型：当lt's tine后用that从句时应该为主i吾+should+动词原形或主语十过去时，例如：It，s time thatyou went to school.或It's time that you should go to schooL
    3- If only引起的感叹句相当于“How I wish+宾语从句”。
    (l)If only he could come.他要能来就好了。
    (2)If only I had known the answer.我要早知道答案就好了。
    4.WOuld rather，as if(though)引导的从句也需使用虚拟语气，表示过去的情况用过去完成时，表示现在与将来的情况用过去时，例如：
    (l)I'd rather you posted the letter right away.
    (2)She loves the children as if they were hers.
    5.含蓄虚拟条件句含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。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(倘若……)，for fear that(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。
    注意：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解。
    (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 wouldn't 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!
