連詞while除具有“當(dāng)時(shí)”、“同時(shí)”等意義外,根據(jù)上下文還有以下不同含義及其不同譯法。下面小編就為大家介紹下while的用法說(shuō)明,希望對(duì)大家有用。
while的用法說(shuō)明如下:
一、while作名詞用,表示“一會(huì)兒”“一段時(shí)間”
1.She likes to lie down for a while after lunch.
她喜歡午飯后躺一會(huì)兒。
2.Coming to another country to study requires a big adjustment and it takes a while to fit in.
來(lái)到另一個(gè)國(guó)家求學(xué),需要花一段時(shí)間來(lái)適應(yīng)。
二、While作連詞(1)引導(dǎo)時(shí)間狀語(yǔ)
1.We must strike while the iron is hot.趁熱打鐵。
2.While she was listening to the radio,she fell asleep.
她聽(tīng)著收音機(jī)睡著了。
(2)引起讓步狀語(yǔ)從句,意思是“雖然…但是….”、“盡管…但是…”(多放于句首)1.While he loves his students,he is very strict with them..
雖然他愛(ài)他的學(xué)生,可是他對(duì)他們很嚴(yán)格。
2.While these experiments are interesting and useful,it is important to remember that they may not always tell us much.(BookIIIp125)
雖然這些實(shí)驗(yàn)很有趣也有用,但是很重要的是要記住,這些實(shí)驗(yàn)也可能不會(huì)告訴你很多。
(3)引起條件狀語(yǔ),意思是“只要”
1.While there is life there is hope.只要生命存在,就有希望。
2.While there is a way there is away.有志者事竟成。
三、While作并列連詞用,意思為“而,然而”,表對(duì)比。而but表轉(zhuǎn)折。注意用心比較體會(huì)while與but的句中用意
1.Some people waste food while others haven't enough.
有些人很費(fèi)糧食,然而有些人卻吃不飽。
2.The son was having a good meal at home,while the parents were working in the fields.
兒子在家吃好飯而父母卻在田里辛勤勞作。
3.I ought to have helped her,but I never could.
我本該幫她但沒(méi)能。
4.Honey is sweet,but the bee stings.
蜂蜜很甜,但蜜蜂有刺蜇人。
四.while,when,as的用法區(qū)別
都譯為“當(dāng)…的時(shí)候”,區(qū)別為:when后的從句謂語(yǔ)動(dòng)詞既可是延續(xù)性動(dòng)詞,也可是短暫性動(dòng)詞,而且還可作并列連詞,譯為“這時(shí)”。但以下句型一定用when,作并列連詞:
句型A:be about to do…when…正要做…這時(shí)(發(fā)生另一事)
句型B:was/were doing…when…正在…這時(shí)(發(fā)生另一事)
句型C:had done…when…剛要做…這時(shí)(發(fā)生另一事)
1.We were about to set out when it began to rain.
我們剛要出發(fā)天突然下雨了。
2.He had hardly sat down when his mobile rang.
他剛一坐下手機(jī)就響了。
3.I was walking along the bank of the river when I fell into it.
我正沿河岸散步突然掉進(jìn)水里。
while后的從句謂語(yǔ)動(dòng)詞只能是延續(xù)性動(dòng)詞,強(qiáng)調(diào)主從句的兩個(gè)動(dòng)詞同時(shí)發(fā)生;while也可作并列連詞,表示兩個(gè)動(dòng)作的對(duì)比,譯為“而”“然而”。as則表示兩個(gè)變化中的動(dòng)作的同時(shí)性,譯為“一邊…一邊…”。
1.While his mother was cooking in the kitchen,the boy fell asleep in the chair.
(在一個(gè)延續(xù)動(dòng)作過(guò)程中發(fā)生另一個(gè)動(dòng)作)
2.He hurried home,looking behind as he went.
他匆匆回家,邊走邊往后看。

2.It was raining while we arrived.
3.She sang while he walked.
4.I don't know them well,while they are my neighbors.
