Unit 2 Poems Section Ⅲ Grammar——虚拟语气(Ⅱ)一、与过去事实相反的虚拟语气从句主句if＋主语＋had＋过去分词主语＋should/would/could/might have＋过去分词如 ： If the weather had been nice yesterday, we would have gone for a picnic.如果昨天天气好的话，我们就去野餐了。If you had come earlier, you could have caught the bus.如果你早一点儿来的话，你就能赶上公交车了。二、虚拟语气在名词性从句中的应用1．宾语从句(1)在表示建议、要求、愿望、命令、坚持 (advise, command, demand, decide, desire, insist, order, prefer, propose, request, require, suggest)等动词后面的宾语从句，或这些动词的同源名词后面所跟的同位语从句或表语从句中，从句谓语用“ should＋动词原形”，其中在美式英语中，should 常省略。如：The doctor advised that he change his job.医生建议他换工作。【温馨提示】当 suggest 表示“暗示、表明”以及 insist 表示“坚持认为、坚持说”时，其后宾语从句表示一种事实，故不用虚拟语气，而用陈述语气。如：He insisted that he had never stolen the money.他坚持说自己没有偷钱。【巧学助记】一坚持(insist)二命令(order, command)三建议(advise, suggest, propose)四要求(demand, require, request, desire)(2)“wish＋宾语从句”表示不可能实现的愿望，汉语可译为“可惜……；悔不该……；但愿……”。表示现在不能实现的愿望，从句的谓语动词用过去式；表示将来不可能实现的愿望用“would/could＋动词原形”；表示过去不可能实现的愿望时用“had＋过去分词”。如：I wish I were betterlooking.要是我长得再漂亮些就好了。I wish I had met the film star just now.我要是刚才遇到那位电影明星该多好啊！I wish I would be a soldier.我希望自己做一名军人。2．主语从句(1) 在 It is ＋ 形 容 词 (important, necessary, good, right, wrong, better, natural, proper, funny, strange, surprising)＋that 从句中，谓语动词的虚拟语气用“(should)＋动词原形”的结构。如：It is natural that she (should) do so.很自然她应该这样做。(2)It be＋过去分词＋that...(should)．..。用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词。如：desired, sugg...
