初中英語(yǔ)語(yǔ)法知識(shí)點(diǎn)總結(jié)2
I.要點(diǎn)
表示說的話不是事實(shí)，或者是不可能發(fā)生的情況，而是一種愿望、建議或與事實(shí)相反的假設(shè)等。一般常用于正式的書面語(yǔ)中。
1、虛擬語(yǔ)氣的構(gòu)成
如：與現(xiàn)在事實(shí)相反
If I had more time, I should study German.(fact:I have no more time, so I shall not study German. )
If she were not so busy, she would attend the meeting this afternoon.(fact:she is very busy, so she will not attend the meeting this afternoon.)
If they didn’t take physical exercises every day, they wouldn’t be so healthy.(fact: they take physical exercises every day, so they are very healthy.)
與過去事實(shí)相反：
I would have checked my paper again if I had had more time at yesterday’s examination.(fact:I had no more time at yesterday’s exam, so I didn’t check my paper again)
You would have already recovered from his illness if he had seen the doctor in good time.(fact: He didn’t see the doctor in good time ,so he hasn’t recovered from his illness )
與將來(lái)事實(shí)相反：
If it rains tomorrow, our picnic will be put off.(The weather has been changeable these days.)
If it rained tomorrow, our picnic would be put off.( The weather has beenvery good these days.)
If it should rain tomorrow, our picnic would be put off.(That would be out of our expectation.)
If it were to rain tomorrow, our picnic would be put off. (條件從句謂語(yǔ)動(dòng)詞用were to +動(dòng)詞原形，表示下雨的可能性極小。Were to rain和should rain都表示“出乎意料之外”，但were to加強(qiáng)表示“當(dāng)初沒想到以后的事”)
注：
(1)如果條件從句謂語(yǔ)動(dòng)詞包含有were或had, should, could有時(shí)可將if省去,但要倒裝。如：
Had you (If you had) invited us, we would have come to your party.
(2)混合時(shí)間條件句的用法：
有時(shí)條件從句的動(dòng)作和主句動(dòng)作發(fā)生的時(shí)間不一致。這時(shí)動(dòng)詞的`形式，應(yīng)根據(jù)它所要表達(dá)的具體時(shí)間來(lái)決定用什么形式。
1) If she hadn’t trained so hard, she wouldn’t be run so fast.(從句敘述過去，主句敘述現(xiàn)在。)
(fact: she has trained very hard, so she would able to run fast.)
2)You would speak English well enough if you had practised reading and speaking it every day.(主句敘述現(xiàn)在，從句敘述過去)
(fact: You didn’t practice (hasn’t practiced ) reading and speaking it every day, so you can’t speak English well enough.)
(3)在其他狀語(yǔ)從句中的用法
主要用于由as if (as though)引導(dǎo)的比較狀語(yǔ)從句，從句中謂語(yǔ)動(dòng)詞一般用“動(dòng)詞的過去式(be變were )或had +過去分詞�！比纾�
She looked as if she were ill.(實(shí)際上她沒有病，在這里用虛擬語(yǔ)氣補(bǔ)語(yǔ)比喻她精神不佳)
Xiao Liu speaks English so well as if he had studied in England.(這里用虛擬語(yǔ)氣表現(xiàn)他的英語(yǔ)說得好)
2、虛擬語(yǔ)氣在各種從句的應(yīng)用
(1)在主語(yǔ)從句中用來(lái)表示驚奇、惋惜、理應(yīng)如此等，其謂語(yǔ)形式是"should(可省) +動(dòng)詞原形"，常用于以下三種句型中。
句型一：It is necessary (important, natural, strange, etc) that…
句型二：It is a pity (a shame, no wonder, etc) that…
句型三：It is suggested (requested, proposed, desired, etc) that…
如：It is strange that he (should) have done that.
It is a pity that he (should) be so careless.
It is requested that we (should) be so careless.
(2)在賓語(yǔ)從句中用于suggest, propose, move, insist, desire, demand, request, order, command等動(dòng)詞后的賓語(yǔ)從句中，表間接的命令和建議。其謂語(yǔ)形式是"(should)+動(dòng)詞原形"。如：
I suggest that we (should) go swimming.
(3)在表語(yǔ)從句中，表示間接的命令，要求、請(qǐng)求、建議、決定等，主句中的主語(yǔ)通常是suggestion, proposal, request, orders, idea等。從句謂語(yǔ)形式是"(should)+動(dòng)詞原形"。如：
His suggestion is that we (should) leave at once.
(4)在同位語(yǔ)從句中，謂語(yǔ)形式是"(should)+動(dòng)詞原形"。如：
We received order that the work be done at once.
(5)在It is time that…句型中，其謂語(yǔ)動(dòng)詞形式是"動(dòng)詞的過去式"或"should +動(dòng)詞原形",should不可省。如：
It's time (that) we went ( should go) to school.
