最新when和while引導(dǎo)的時(shí)間狀語(yǔ)從句與這一時(shí)態(tài)連用資料

1、when 和 while 引導(dǎo)的時(shí)間狀語(yǔ)從句與這一時(shí)態(tài)連用。所以區(qū)別 when 和 while 的用法成了這一單元的難點(diǎn)。（一）、when , while都有 當(dāng) 時(shí)候"的意思。when 既可表示某一點(diǎn)時(shí)間，也可以表示某一段時(shí)間 。在 when 引導(dǎo)的時(shí)間狀語(yǔ)從句中，其謂語(yǔ)動(dòng)詞可以是延續(xù)性的，也可以是非延 續(xù)性的，可與主句中的謂語(yǔ)動(dòng)詞同時(shí)發(fā)生，也可在其后發(fā)生。例如：1 、 I was just reading a book when she came into my room.她走進(jìn)我房間時(shí)，我正在看書(shū)。2 、 Were you writing when the teacher ca

2、me in?老師進(jìn)來(lái)的時(shí)候，你在寫(xiě)信嗎？3 、 When he was a child he was always trying out new ideas.他小時(shí)候就常常試驗(yàn)一些新的設(shè)想。（二）、 while 只能表示某一段時(shí)間，不能表示某一點(diǎn)時(shí)間。在 while 引導(dǎo)的時(shí)間狀語(yǔ)從句中，其謂語(yǔ)動(dòng)詞只能是延續(xù)性的，而且也只 能與主句中的謂語(yǔ)動(dòng)詞同時(shí)發(fā)生或存在。例如：1、While Jim was mending his bike, Lin Tao came to see him.正當(dāng)吉姆修自行車時(shí)，林濤來(lái)看他。2、 You can ' t do your homework while

3、you' re watching TV.你不能一邊看電視一邊做家庭作業(yè)。（三）、另外， when 和 while 的區(qū)別還在于： while 引導(dǎo)的時(shí)間狀語(yǔ)從句多用進(jìn)行時(shí)態(tài)，而 when 引導(dǎo)的時(shí)間狀語(yǔ)從句多用一般時(shí)態(tài)。 例如：1 、 While they were talking , the bell rang.正在他們談話的時(shí)候，上課鈴響了。2 、 I was doing my homework when my mother came back home yesterday evening.昨天晚上媽媽回家的時(shí)候，我正在做家庭作1. she comes , I shall tell

Thatwhen as while when 表示較短的時(shí)間 , 有的時(shí)候也可以指一段時(shí)間。如 :When he was young, he could do eat much more than his brother. while 常表示一段

5、較長(zhǎng)的時(shí)間 , 強(qiáng)調(diào)主句謂語(yǔ)動(dòng)詞與從句謂語(yǔ)動(dòng)詞同時(shí)發(fā)生。如:你的第三道題就是這樣。 只用 as, 不用 when 或 while 的時(shí)候。A）用于表示同一個(gè)人的兩種動(dòng)作交替進(jìn)行，指"一邊，一邊"。如：The girl dan ces as she sings on the stage.B）表示兩個(gè)同步發(fā)展的動(dòng)作或行為，譯為“隨著"。如:As time went on, she became more and more worried.when和while的區(qū)別都表示“當(dāng) 時(shí)候”的區(qū)別。請(qǐng)觀察以下句子:While in Vienna he studied music

6、.他在維也納時(shí)學(xué)習(xí)音樂(lè)。While he was eating, I asked him to lend me $2.當(dāng)他正在吃飯時(shí)，我請(qǐng)他借給我二英鎊others opened the parcel.were keeping guard at the door, two這時(shí)兩個(gè)偵探把著門，另外兩個(gè)打開(kāi)包裹While I read, she sang.我看書(shū)時(shí)，她在唱歌。I met her while I was at school.當(dāng)我在學(xué)校的時(shí)候我遇見(jiàn)了她。Edison was not a good student when he was a young boy.愛(ài)迪生小時(shí)候不是一個(gè)成績(jī)好

7、的學(xué)生。When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on theairfield.當(dāng)飛機(jī)抵達(dá)時(shí)，一部分偵探等在主樓里面，而另一部分則等在停機(jī)坪上。When I came home my wife was cooking dinner.我回家時(shí)，妻子在做晚飯。引導(dǎo)的從句里的動(dòng)作發(fā)生通過(guò)觀察，我們可以這樣理解：when引導(dǎo)的從句里動(dòng)作發(fā)生的時(shí)間相對(duì)主句動(dòng)作發(fā)生的時(shí)間要短些；while的時(shí)間相對(duì)主句而言更長(zhǎng)些。333 as

8、， when，while 意為 although （盡管），but （但是）， seeing that （鑒于）A 只有在形容詞 +as+主語(yǔ) +to be/to seen）/to appear 這一結(jié)構(gòu)中，as 才意為 though /although （盡管）：Tired as he was he offered to carry her相當(dāng)于：Though he was tired he offered to carry her盡管他很累了，他還主動(dòng)提出要背著她。Strong as he was ， he couldn 't lift it 盡管他力氣很大，他仍提不起這個(gè)東西。B

9、 while 可意為 but ，用于表示強(qiáng)調(diào)對(duì)比：At sea 'm eanson a ship '， while at the sea 'meansat the seaside'“At sea ”意為“在船上”，而“ at the sea ”意為“在海灘上”。Some people waste food while others haven 't enough 一些人糟踏食物而另一些人卻食不果腹。while 可以意為 although ，這時(shí)常放在句首：While I sympathize with your point of view I cannot accept it精品文檔盡管我認(rèn)同你的觀點(diǎn)，但我不能接受它。C when 可以意為 seeing that although （鑒于）。因此它同 while 很相似，但主要用于引導(dǎo) 使另一個(gè)動(dòng)作顯得不合理的陳述句。它常用在一個(gè)問(wèn)句里，但不是一定如此：How can you expect your children to be truthful when you yourself tell lies？你自己都在撒謊，怎么能指望你的孩子們誠(chéng)實(shí)？It ' s not fair to expect her to do all the cooking when she has had
