關(guān)于when while as 選擇題,when while這個問題很多朋友還不知道,今天小六來為大家解答以上的問題,現(xiàn)在讓我們一起來看看吧!
1、when,while,as引導(dǎo)時間狀語從句的區(qū)別 when,while,as顯然都可以引導(dǎo)時間狀語從句,但用法區(qū)別非常大。
2、 一、when可以和延續(xù)性動詞連用,也可以和短暫性動詞連用;而while和as只能和延續(xù)性動詞連用。
3、 ① Why do you want a new job when youve got such a good one already?(get為短暫性動詞)你已經(jīng)找到如此好的工作,為何還想再找新的? ②Sorry,I was out when you called me.(call為短暫性動詞)對不起,你打電話時我剛好外出了。
4、 ③Strike while the iron is hot.(is為延續(xù)性動詞,表示一種持續(xù)的狀態(tài))趁熱打鐵。
5、 ④ The students took notes as they listened.(listen為延續(xù)性動詞)學(xué)生們邊聽課邊做筆記。
6、 二、when從句的謂語動詞可以在主句謂語動作之前、之后或同時發(fā)生;while和as從句的謂語動作必須是和主句謂語動作同時發(fā)生。
7、 1.從句動作在主句動作前發(fā)生,只用 when。
8、 ①When he had finished his homework,he took a short rest.(finished先發(fā)生)當(dāng)他完成作業(yè)后,他休息了一會兒。
9、 ②When I got to the airport,the guests had left.(got to后發(fā)生)當(dāng)我趕到飛機場時,客人們已經(jīng)離開了。
10、 2.從句動作和主句動作同時發(fā)生,且從句動作為延續(xù)性動詞時,when,while,as都可使用。
11、 ①When /While /As we were dancing,a stranger came in.(dance為延續(xù)性動詞)當(dāng)我們跳舞時,一位陌生人走了進(jìn)來。
12、 ②When /While /As she was making a phonecall,I was writing a letter.(make為延續(xù)性動詞)當(dāng)她在打電話時,我正在寫信。
13、 3.當(dāng)主句、從句動作同時進(jìn)行,從句動作的時間概念淡化,而主要表示主句動作發(fā)生的背景或條件時,只能用 as。
14、這時,as常表示“隨著……”;“一邊……,一邊……”之意。
15、 ① As the time went on,the weather got worse.(as表示“隨著……”之意) ② The atmosphere gets thinner and thinner as the height increases.隨著高度的增加,大氣越來越稀薄。
16、 ③As years go by,China is getting stronger and richer.隨著時間一年一年過去,中國變得越來越富強了。
17、 ④The little girls sang as they went.小姑娘們一邊走,一邊唱。
18、 ⑤The sad mother sat on the roadside,shouting as she was crying.傷心的媽媽坐在路邊,邊哭邊叫。
19、 4.在將來時從句中,常用when,且從句須用一般時代替將來時。
20、 ①You shall borrow the book when I have finished reading it.在我讀完這本書后,你可以借閱。
21、 ②When the manager comes here for a visit next week,Ill talk with him about this.下周,經(jīng)理來這參觀時,我會和他談?wù)劥耸隆?/p>
22、 三、when用于表示“一……就……”的句型中(指過去的事情)。
23、 sb.had hardly(=scarcely) done sth.when...=Hardly / Scarcely had sb.done sth.when... ①I had hardly /scarcely closed my eyes when someone knocked at the door.=Hardly / Scarcely had I closed my eyes when someone knocked at the door.我剛一閉上眼,就有人在敲門了。
24、 ②I had hardly /scarcely entered my room when the telephone rang.=Hardly /Scarcely had I entered my room when the telephone rang.我剛一走進(jìn)房門,電話就響了。
