      until的用法詳解

      時(shí)間: 焯杰674 分享

        下面學(xué)習(xí)啦小編為大家?guī)?lái)Until的用法詳解:

        表示“直到……為止”,兩者??蓳Q用,只是 until 比 till稍正式,所以在正式文體中,一般用 until,而在口語(yǔ)或非正式文體中則兩者都可用.從其后所接成分來(lái)看,till多與名詞或較短的從句連用,而較長(zhǎng)較復(fù)雜的成分多用 until,位于句首時(shí)也多用 until.兩者在用法上應(yīng)注意以下幾點(diǎn):

        1.引導(dǎo)時(shí)間狀語(yǔ)從句時(shí),其謂語(yǔ)要用現(xiàn)在時(shí)表示將來(lái)意義.如:

        I won’t leave until he comes back tomorrow.我要等他明天回來(lái)后再走.

        Continue in this direction until you see a sign.一直朝著這個(gè)方向走就看見指示牌了.

        2.相關(guān)主句謂語(yǔ)必須是持續(xù)性動(dòng)詞,若是終止性動(dòng)詞,則應(yīng)為否定式(因?yàn)榻K上性動(dòng)詞一旦被否定就成為狀態(tài),便可持續(xù)).如:

        He waited until she was about to leave.他等著一直到她準(zhǔn)備離開.

        She didn’t marry until she was over fifty.她直到50多歲才結(jié)婚.

        3.有時(shí)其后可跟副詞或介詞短語(yǔ)等.如:

        He has been ill until recently.他最近一直生病.

        Until when are you going to stay here?你在這兒要待到什么時(shí)候?

        We didn’t eat till past midnight.直到午夜過(guò)后我們才吃飯.

        She won’t go home until after the exam.她要考完試之后再回家.

        如果語(yǔ)境的需要,有時(shí)甚至可以接帶有“引導(dǎo)詞”的從句.如:

        Don’t leave until after I’ve spoken to you.我和你說(shuō)完后再離開.

        4.用于 not…until [till]…結(jié)構(gòu)

        (1) 可用于It is (was) not until [till]…that…這樣的強(qiáng)調(diào)句型.如:

        It was not until I met you that I knew real happiness.直到我遇到你以后,我才真正體會(huì)到幸福.

        It was not until she took off her dark glasses that I realized she was a famous film star.直到她取下墨鏡,我才意識(shí)到她是一位著名影星.

        (2) 若主句動(dòng)詞為終止性動(dòng)詞,其意為“直到……才……”;若主句為持續(xù)性動(dòng)詞,其意為“不到……就……”.比較:

        They didn’t find her till the next day.他們直到第二天才找到她.

        He didn’t wait until I returned.他沒等到我回來(lái)(沒等我回來(lái)他就走了).

        有時(shí) until 或 till 可以換成 before.如:

        Until [Before] you told me,I had no idea of it.在你告訴我之前,我對(duì)此一無(wú)所知.(即直到你告訴我,我才知道)

        (3) 若將not until [till]置于句首,其后的主句要用倒裝語(yǔ)序.如:

        Not until much later did she learn who her real father was.她很久以后才知道她真正的父親是誰(shuí).

        Not until he received her letter did he fully understand the depth of her feelings.他直到收到她的信之后才充分理解她的感情有多深.

        until雙語(yǔ)例句:

        1、From September until December, Congress remained in session.

        從9月到12月,國(guó)會(huì)一直都在開會(huì)。

        2、The aid will not be disbursed until next year.

        援助款到明年才會(huì)下?lián)堋?/p>

        3、Sarah was nine years old and until that moment she had been locked in a world of her own.

        薩拉當(dāng)時(shí)9歲,之前她一直封閉在自己的世界里。

        4、Our pilot reduced height until we hugged the ground.

        飛行員降低了高度,最后我們緊貼著地面飛行。

        5、The prospect of having to pay a graduate tax until retirement would kill the students 'enthusiasm stone dead.

        想到今后一直到退休為止都要繳畢業(yè)稅,學(xué)生們的積極性會(huì)被徹底打消。
