英文語(yǔ)法雜談：虛擬語(yǔ)氣 （一）

　　如果你看到下列的句子，你會(huì)認(rèn)為它們是正確的還是錯(cuò)的呢?

　　1.　I wish I were a bird.

　　2.　We request that you be here tomorrow.

　　也許你會(huì)說(shuō)：“哈哈，第一句的I were 錯(cuò)了，應(yīng)該是I was;而第二句中的you be是什么東東呀?不是you are, 也不是you will be, 什么you be?!”

　　其實(shí)上面的句子都是一種稱(chēng)為 Subjunctive 類(lèi)型的句子。Subjunctive Mood 有的書(shū)譯為“假設(shè)語(yǔ)氣”，雖不很貼切;但在相當(dāng)大的程度上，告訴我們這種句子的特點(diǎn)，Subjunctive Mood中文譯作“虛擬語(yǔ)氣”，似乎不及“假設(shè)語(yǔ)氣”那么容易明白。它是一種動(dòng)詞形式，表示說(shuō)話(huà)人的某種假設(shè)、愿望、懷疑、猜測(cè)、建議等含義。

　　基本上，虛擬語(yǔ)氣可分為虛擬現(xiàn)在(Subjunctive Present)和虛擬過(guò)去(Subjunctive Past)兩種;但它們和時(shí)態(tài)(Tenses)上所指的現(xiàn)在時(shí)態(tài)(Present Tense)和過(guò)去時(shí)態(tài)(Past Tense)是有所不同的。

　　一、虛擬現(xiàn)在(Subjunctive Present)

　　虛擬現(xiàn)在的句子，在任何時(shí)候都要用動(dòng)詞的原形(root form)，就算是第三人稱(chēng)(he, she, it)也是如此。如：

　　1.1　現(xiàn)在時(shí)態(tài)(Simple Present)

　　I work ---- I work

　　you work ---- you work

　　he works ---- he work (注意到了嗎，是work，不是works)

　　she works ---- she work (不是she works 喔)

　　it works ---- it work　(同樣不是it works 喔)

　　we work ---- we work

　　they work ---- they work

　　1.2　現(xiàn)在進(jìn)行時(shí)態(tài)(Present Continuous)

　　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　現(xiàn)在完成時(shí)態(tài)(Present Perfect)

　　I have worked ---- I have worked

　　you have worked ---- you have worked

　　he has worked ----- he have worked (用的還是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　現(xiàn)在完成進(jìn)行時(shí)態(tài)(Present Perfect Continuous)

　　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
