【摘要】：進(jìn)入秋季，各個(gè)高中都已經(jīng)進(jìn)入了高三年級(jí)一輪復(fù)習(xí)階段。一輪復(fù)習(xí)是高考復(fù)習(xí)中內(nèi)容最全面、最細(xì)致的一輪，也決定了同學(xué)們賴以迎接考試的知識(shí)基礎(chǔ)是否牢靠。因此，如果希望在高考中取得優(yōu)異的成績，一輪復(fù)習(xí)時(shí)需要有良好的方法和復(fù)習(xí)效果。在此，小編為同學(xué)們整理了“高考英語虛擬語氣考點(diǎn)”，希望能對(duì)大家所有幫助。
高考英語虛擬語氣考點(diǎn)如下：
一、虛擬條件句
條件狀語從句是非真實(shí)情況，在這種情況下要用虛擬語氣。
l-條件從句與現(xiàn)在事實(shí)不一致，句型為：If+主語十過去時(shí)，tiag+should (could，would，或might)+動(dòng)詞原形，例如：If l were you，1 would study hard.
2.條件從句與過去事實(shí)不一致，句型為：If+主語+had+過去分詞，主語+should(could, would，或might)+have+過去分詞，例如：If I had not studied hard.1would have failed in the exam last term
3.條件從句與將來事實(shí)不一致，句型為：lf+主語+should/were to+do，主語+should( could.)+原形do，例如：If l were to go to the moon one day,I could see itwith my own eyes.
注意：
1.If條件句中絕對(duì)不可出現(xiàn)“would”。
2-根據(jù)句中的時(shí)間狀語，有時(shí)可能出現(xiàn)“混合虛擬”的情況，即主句可能是現(xiàn)在的情況，條件句也許是發(fā)生在過去的情況，但都遵守上述句型。
3.在條件句中如果出現(xiàn)were，had，should可省去if'
將這些詞提前置于句首構(gòu)成倒裝，例如：w。re I to go tothe moon one clay,1 would see it with my own eyes.如果有一天我登上月球，我就可以親眼目睹它的樣子了。
二，名詞性虛擬語氣
在表示命令、建議、要求、驚嘆的名詞性從句中需用虛擬語氣�；揪湫蜑椋褐髡Z+should+動(dòng)詞原形，例如：
1.Mother insisted that John (should) go to bed atnine o'clock(賓語從句)
2.It was required that the crops (should) be:harvested at once.(主語從句)
3.The suggestion that he (should) be 高中語文 invited wasrejected.(同位語從句)
4.That is their demand that their wages (should) bemcreased.(表語從句)
注意：在這種句子中絕不能出現(xiàn)“would”“must”
“could”等。
三、虛擬語氣在一些特殊詞中的使用或含蓄條件句
1.wish后的賓語從句。
與現(xiàn)在愿望不一致，用主語十過去時(shí)，例如：
I wi。hIwere you.
與過去愿望不一致，用主語+had+過去分詞，例如：Iwish I had visited the White House whenI was in the States與將來愿望不一致，用主語+would (could)+原形。
2.It's time句型：當(dāng)lt's tin】e后用that從句時(shí)應(yīng)該為主i吾+should+動(dòng)詞原形或主語十過去時(shí)，例如：It，s time thatyou went to school.或It's time that you should go to schooL
3- If only引起的感嘆句相當(dāng)于“How I wish+賓語從句”。
(l)If only he could come.他要能來就好了。
(2)If only I had known the answer.我要早知道答案就好了。
4.WOuld rather，as if(though)引導(dǎo)的從句也需使用虛擬語氣，表示過去的情況用過去完成時(shí)，表示現(xiàn)在與將來的情況用過去時(shí)，例如：
(l)I'd rather you posted the letter right away.
(2)She loves the children as if they were hers.
5.含蓄虛擬條件句含蓄條件句是指句中沒有明顯的虛擬條件句，而是利用其他手段來暗示存在虛擬條件。但是這類隱含式虛擬條件句往往都可以轉(zhuǎn)化為if引導(dǎo)的條件句。常用來表示含蓄虛擬條件的手段有：
(1)介詞或介詞短語。如but for，but that，without,in case of, under more favorable condition等。
(2)連詞。如so that, unless, in case, supposing,lest, provided(倘若……)，for fear that(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。
注意：lest, for fear that和in case引起的從句中謂語動(dòng)詞多用should+動(dòng)詞原形，但也可以不用虛擬語氣，而用動(dòng)詞的陳述語氣形式。例如：The foreign teacher spokeslowly in case we misunderstood him這位外籍教師說得很慢以免我們誤解。
(3)通過上下文及內(nèi)在含義，句中往往有but,otherwise, unfortunately等類似轉(zhuǎn)折詞。
without, but. but for, otherwise引起的短語或句子常暗含著含蓄條件。例如：
①Without you,1 would never know him
②But for your oooperation, we wouldn't have done it
③But that she was afraid, she would have said no. .
④i would be most glad to help you, butI am busy now.
⑤I would have come to the party yesterday, but ljwas working.
⑥I am busy now, otherwise l would do you the favor!
【總結(jié)】高考英語虛擬語氣考點(diǎn)到這里就結(jié)束了，希望大家好好復(fù)習(xí)，未來是屬于你們的。
