2、动词原形假设情况条件从句的谓语形式主句的谓语形式与将来事实相反一般过去时(be的过去式常用were)should动词原形were to动词原形would/should/might/could动词原形与过去事实相反过去完成时(had过去分词)would/should/might/couldhave过去分词备注：与过去事实相反的虚拟语气，将在第二单元中细讲，此处只列出(1)与现在事实相反If I were you,I would tell him the good news.要是我是你，我就会告诉他这个好消息。If we had time now,we should read it again.要

4、you do?如果真发生这样的事，你怎么办呢？11 Had I known about this computer program,a huge amount of time and energy _.Awould have been savedBhad been savedCwill be saved Dwas saved解析：选。考查虚拟语气。从前面had I known about.知，此处是if条件句对过去情况的虚拟，所以主句用should/would/could/mighthave done结构，故排除B、C、D项，选A项。考题印证1A12 This printer is of go

5、od quality.Ifit_break down within the first year,we would repair it at our expense.Awould BshouldCcould Dmight解析：选。考查虚拟语气。句意：这种打印机质量优良。如果它在第一年中出了毛病，我们将无偿维修。这是在条件句中对将来情况的虚拟，用“should动词原形”。B2宾语从句中的虚拟语气(1)wish后的宾语从句使用虚拟语气，表示不能实现的愿望。主句用法从句谓语动词的形式主语wish表示现在不能实现的愿望用一般过去时(be通常用were)表示过去不能实现的愿望had过去分词表示将来不能实

6、现的愿望would(could)动词原形I wish I knew what was going to happen.但愿我能知道发生什么事。He wishes he could become a scientist some day.他希望将来的某一天能成为科学家。Where are the children?The dinners going to be completely ruined.I wish they_ always late.Awerent Bhadnt beenCwouldnt be Dwouldnt have been解析：选。考查虚拟语气。根据问句句意“孩子们现在在哪里

7、？”可知wish 后的宾语从句应用动词的过去式，表示与现在事实相反的愿望，故答案为A。考题印证2A(2)在表示命令、建议、要求等一类动词后面的从句中，谓语动词用“should动词原形”表示虚拟，should可以省略。这类动词，我们可以使用下面的口诀记忆。一坚持(insist)二命令(order,command)三建议(suggest,propose,advise)四要求(require,request,desire,demand)I suggest that we(should)practise speaking English every day.我建议我们应该每天都练习讲英语。He ins

8、isted that he(should)be sent there.他坚持应该被派去那里。点津当insist表示“坚持认为；坚持说”，suggest表示“表明；暗示”时，后面的宾语从句不用虚拟语气。He insisted that he had done nothing wrong.他坚持说他没有做错。The smile on his face suggested that he was satisfied with our work.他脸上的笑容表明他对我们的工作很满意。31 Teachers recommend parents _ their children under 12 to r

9、ide bicycles to school for safety.Anot allow Bdo not allowCmustnt allow Dcouldnt allow解析：选。考查虚拟语气。recommend后跟宾语从句应用虚拟语气，其结构为“(should)动词原形”，这里省略了should，故A正确。考题印证3A32 The doctor recommended that you_swim after eating a large meal.Awouldnt BcouldntCneednt Dshouldnt解析：选。考查虚拟语气。recommend，suggest，demand等词

10、后面的宾语从句应该用虚拟语气，从句中的谓语动词用shoulddo，should可以省略。故选D项。D(3)在would rather句型中的虚拟语气。在would rather后面所跟的从句中，也可用虚拟语气。表示愿望，意为“宁愿；但愿”。其形式为：would rather主语动词过去式表示现在或将来的情况would rather主语had动词过去分词表示过去的情况I would rather you did not go tomorrow.我宁愿你明天不去。I would rather she hadnt done that.我宁愿她没那样做。George is going to talk

16、的语言(1)建议信就是在你所写的信中发表你的建议与看法。建议信除要遵循书信的格式之外，还要求在信中针对别人的问题，给出你的观点及解决办法。因此，陈述建议的语言必须中肯，在劝说对方接受自己的建议时，应该特别注意措辞。(2)陈述建议必须具有说服性：在向对方表明你的建议时，如果对方觉得你的建议是违背常理的，那么你的建议也就失去了意义。所以，要想提出好建议，必须具有充分的理由，展示出自己独特的见解。(3)此外，要“设身处地”，可适当运用虚拟句“if I were you.”表述自己的建议。2建议信的结构建议信一般采取“三段式结构”，通常以firstly,secondly,thirdly或to begi
