小学阶段需掌握的英语语法 谈谈虚拟语气小学英语课堂,如果你看到下列的句子，你会认为它们是正确的还是错的呢? 　　1.I wish I were a bird. 　　2.We request that you be here tomorrow. 　　也许你会说:"哈哈，第一句的 I were 错了，应该是 I was;而第二句中的 you be是什么东东呀?不是 you are, 也不是 you will be, 什么 you be?!"其实上面的句子都是一种称为 Subjunctive 类型的句子。Subjunctive Mood 有的书译为"假设语气"，虽不很贴切;但在相当大的程度上，告诉我们这种句子的特点。Subjunctive Mood中文译作"虚拟语气"，似乎不及"假设语气"那么容易明白。它是一种动词形式，表示说话人的某种假设、愿望、怀疑、猜测、建议等含义。基本上，虚拟语气可分为虚拟现在(Subjunctive Present)和虚拟过去(Subjunctive Past)两种;但它们和时态(Tenses)上所指的现在时态(Present Tense)和过去时态(Past Tense)是有所不同的。 　　一、虚拟现在(Subjunctive Present): 　　虚拟现在的句子，在任何时候都要用动词的原形(root form)，就算是第三人称(he,she, it)也是如此。如： 　　1.1 现在时态(Simple Present): (右边为虚拟语气) 　　I work ---- I work 　　you work ---- you work 　　he works ---- he work (注意到了吗，是 work，不是 works) 　　she works ---- she work (不是 she works 喔) 　　it works ---- it work　(同样不是 it works 喔) 　　we work ---- we work 　　they work ---- they work 　　1.2　现在进行时态(Present Continuous):(右边为虚拟语气) 　　I am working ---- I be working (注意用的是 be，怪怪的!) 　　you are working ---- you be working 　　he is working ---- he be working 　　she is working ---- she be working 　　it is working ---- it be working 　　we are working ---- we be working 　　they are woring ---- they be working 　　1.3　现在完成时态(Present Perfect):(右边为虚拟语气) 　　I have worked ---- I have worked 　　you have worked ---- you have worked 　　he has worked ----- he have worked (用的还是have喔) 　　she has worked ---- she have worked 　　it has worked ---- it have worked 　　we have worked ---- we have worked 　　they have worked ---- they have worked 　　1.4　现在完成进行时态(Present Perfect Continuous):(右边为虚拟语气) 　　I have been working ---- I have been working 　　you have been working ---- you have been working 　　he has been working ---- he have been working　(是 he have, 不是 he has ) 　　she has been working ---- she have been working 　　it has been working --- it have been working 　　we have been working ---- we have been working 　　they have been working ---- they have been working 　　谈谈虚拟语气(Subjunctive Mood)(二)
