虛擬語氣詳解

1、 精誠所至，金石為開。今天，你給自己加油了嗎？虛擬語氣詳解思考1：什么叫虛擬？在英語當(dāng)中體現(xiàn)為什么？虛擬即不真實(shí)。其表述的事件或事件發(fā)生的條件不可能存在，或者可能性很小。在英語當(dāng)中，虛擬在句子中通過時態(tài)的變化來體現(xiàn)。一般遵循的是時態(tài)往前推一個的原則。虛擬歸根到底，是謂語動詞的變化。思考2：虛擬有哪些類型？我們已經(jīng)見過哪些？1. I could have seen off Jack if I had arrived earlier.2. My uncle suggested that we (should) go there by train.3. Its high time that we s

2、hould go./ were go.4. The chopstick looks as if it were broken in the water.虛擬語氣的分類：if型 should+V. 原形型 似if 型思考：各種類型的虛擬語氣，都長什么樣？1. if 型所述情況從句主句與現(xiàn)在相反If+主語+動詞過去式（be動詞用were）主語 + would / could/might/should+ 動詞原形與過去相反If+主語+動詞過去完成時主語 + would / could/might/should+ have done與將來相反 if+主語+動詞過去式 if+主語+were to + 動

3、詞原形 if+主語+should+動詞原形主語 + would / could/might/should+ 動詞原形2. If型我們需要注意什么？從句和主句有時候所表述的事件發(fā)生的時間段并不一致，這個時候需要我們注意要“各自為準(zhǔn)”If they had started the early morning yesterday, they would be here now.If I were not to make a preparation for my experiment this afternoon, I would have gone to see the film with you

4、last night.If we shouldn't have an exam this afternoon, I would go shopping now.If you had followed my advice, you would be able to finish the work now.If I were you, I would have gone to her birthday party last night.當(dāng)從句中出現(xiàn)had/should/ were 時可以省略if，并將這三個詞當(dāng)中的一個放到if的位置上去，所以要熟悉常見的省略過后if 條件句If I wer

5、e.= Were I. I f I were to.= Were I to.If I should.= Should I . If I had.= Had I.3. should+V. 原形型should 可以省略動詞名詞一個堅(jiān)持insist (堅(jiān)決要求）insistence兩個命令order commandorder command三個建議advice suggest proposeadvice suggestion proposal四個要求demand require ask requestdemand requirement request改錯1.The workers requeste

6、d that he sang a song.2.The workers' requested was that he (should) sing a song.3.The hotel receptionist requires that we paid in cash.4.The hotel receptionists requirement is that we (should) pay in cash.should 不可以省略Its(high/ about) time. 句型4. 似if型wish+從句 （表達(dá)愿望或者祝福） as if / （though）+從句所述情況從句現(xiàn)在主

7、語+動詞一般過去時（過去式）過去主語+動詞過去完成時（had done)將來主語+would/could/might +V.原形我希望年輕30歲。I wish I were 30 years younger.祝你找到一份好工作。I wish (that) you would get a good job.他希望沒做過這件事。He wished he hadnt done it.他對待這個小女孩就像她是自己的女兒一樣。 He treats the little girl as if she were his own daughter.would rather 寧愿. if only. 要是.就好

8、了所述情況謂語動詞過去had + 過去分詞； 現(xiàn)在/將來過去時(be 用were ) 我倒想你昨天看過了這場電影。Id rather you had seen the film yesterday.我倒想你現(xiàn)在在這兒。Id rather you were here now.我么倒想你明天去那兒。Wed rather you went there tomorrow. 如果我能看到他就好了。If only I could see him. 如果我是一只鳥該多好呀! If only I were a bird. . 一些短語相當(dāng)于虛擬條件從句（if）, 其后的句子與虛擬條件主句用法一致but for

9、 +n(要不是), without +n, otherwise(否則)，in that case，所述情況其后的句子過去主語+would/could/should/might+have done現(xiàn)在/將來主語+would/could/should/might +V.原形我本該來看你了，然而我太忙了。I would have come to see you, but I was too busy. 要不是他的幫助，我們還會在工作呢。But for his help, we would be working now. 要是沒有你的指導(dǎo)，我不會取得如此大的進(jìn)步。Without your instru
