春季高考培訓(xùn)學(xué)校_when指導(dǎo)的時(shí)間狀語(yǔ)從句 用法有哪些

中美軍隊(duì)在朝鮮3年戰(zhàn)爭(zhēng)的傷亡比例大致約為2.7比1。 這場(chǎng)戰(zhàn)爭(zhēng)中,中國(guó)先后240萬(wàn)志愿軍跨過(guò)鴨綠江進(jìn)入朝鮮,后面統(tǒng)計(jì)總耗資25億美元?？姑涝?..

when指導(dǎo)的時(shí)間狀語(yǔ)從句可以和延續(xù)性動(dòng)詞連用，也可以和短暫性動(dòng)詞連用；when從句的謂語(yǔ)動(dòng)詞可以在主句謂語(yǔ)動(dòng)作之前、之后或同時(shí)發(fā)生。

一、有“當(dāng)……的時(shí)刻”的寄義(=at the time that...),此時(shí)when后的從句是用來(lái)說(shuō)明前面主句動(dòng)作發(fā)生的靠山.例如:

James pretended to be deaf when I spoke to him.當(dāng)我和詹姆斯講話(huà)的時(shí)刻,他冒充耳聾.

二、有“正……溘然……”的寄義,示意突然發(fā)生某事.此時(shí)是when前的主句說(shuō)明when后面句子之中動(dòng)詞動(dòng)作發(fā)生的靠山.例如:

I was about to leave my office when the telephone rang.我正要脫離辦公室時(shí),溘然電話(huà)鈴響了.

注重:在這種句型中一樣平常不能把when放在句首.

三、有“無(wú)論什么時(shí)刻……”的寄義,與whenever的意思差不多,但語(yǔ)氣較輕.此時(shí)when后的從句說(shuō)明主句動(dòng)詞動(dòng)作發(fā)生的靠山.例如:

When the wind blows,all the doors rattle.只要風(fēng)一吹,所有的門(mén)都吱吱嘎嘎作響.

四、有“本該(可)……而(卻)……”的寄義,此時(shí)when含有對(duì)比意義.例如:

They have only three copies when we need five.我們本該需要五本,而他們卻只有三本.

五、有“既然……”的寄義.此時(shí)when從句說(shuō)明主句的理由或是一種托故.例如:

I can’t tell you anything when you won’t listen.既然你不想聽(tīng),我就不告訴你了.

六、有“若是,要是(=if)”的寄義,此時(shí)when從句示意條件,意思上靠近“在……的情形下”.例如:

Come when you are ready.若是(要是)你準(zhǔn)備好了,就來(lái)吧.

七、有“還沒(méi)(剛剛)……就……”的寄義,此時(shí)示意主、從句的動(dòng)作險(xiǎn)些同時(shí)發(fā)生.例如:

I had hardly opened the door when he hit me.我剛開(kāi)門(mén),他就打我.

八、有“那時(shí)或然后”的寄義,此時(shí)when前往往有“,”號(hào).例如:

唐朝對(duì)西域進(jìn)行治理的方法為：設(shè)安西都護(hù)府、合理安置西域原統(tǒng)治者、加強(qiáng)貨幣管控、加強(qiáng)軍事配置。唐朝為了加強(qiáng)對(duì)西域的控制，效仿西漢，建立了永久性...

They arrive at 6,when we all have dinner.他們六點(diǎn)到,那時(shí)(然后)我們?nèi)巳艘黄鹩蔑?

九、有“著實(shí)或雖然……然則……”的寄義,此時(shí)when的意思靠近although.例如:

She stopped trying,when she might succeed next time.她不再實(shí)驗(yàn)了,著實(shí)下一次說(shuō)不定會(huì)樂(lè)成.

注重:有時(shí)when指導(dǎo)狀語(yǔ)從句時(shí),在不影響文意的情形下往往將從句中某些身分省去,因此,經(jīng)常會(huì)泛起以下結(jié)構(gòu):

1.When+現(xiàn)在分詞.例如:

When sleeping,I never hear a thing.睡覺(jué)時(shí),我什么都聽(tīng)不見(jiàn).

2.When+已往分詞.例如:

This dictionary will look nice when printed.這本詞典印出來(lái)時(shí)會(huì)很悅目.

3.When+名詞或形容詞.例如:

When a boy,he was sick all the time.小的時(shí)刻,他經(jīng)常生病.

4.When+介詞短語(yǔ).例如:

When at Rome do as the Romans do.入鄉(xiāng)隨俗.

2、一樣平常已往時(shí) yesterday, last week, an hour ago, the other day, in 1982, just now

3、一樣平常未來(lái)時(shí) next…, tomorrow, in+時(shí)間
