【文章內(nèi)容簡(jiǎn)介】 動(dòng)作正在發(fā)生，as 從句也可以用正在進(jìn)行時(shí)。這只能算是特例了。1. The sad mother sat on the roadside, shouting as she was crying. 傷心的媽媽坐在路邊，邊哭邊叫喊。 2. As we were going out, it began to snow. 正當(dāng)我們出門時(shí)，雪開始下起來(lái)。3. He came in as I was going to bed. 我正要上床睡覺，他進(jìn)來(lái)了。四、when, while, as 的互換 如果從句動(dòng)作和主句動(dòng)作同時(shí)發(fā)生，并且從句動(dòng)作為延續(xù)性動(dòng)詞時(shí)，when，while，as 可以互換使用。這種情況下，它們的細(xì)微區(qū)別恐怕連英、美人自己也說(shuō)不清了。1. When /While /As we were dancing, a stranger came in. 當(dāng)我們跳舞時(shí)，一位陌生人走了進(jìn)來(lái)。 [dance 為延續(xù)性動(dòng)詞]2. When /While /As she was making a phone call, I was writing a letter. 當(dāng)她在打電話時(shí)，我正在寫信。 [make為延續(xù)性動(dòng)詞]3. While/When/ As I was walking down the street, I noticed a police car in front of the bank. 我順著馬路往前走時(shí)，發(fā)現(xiàn)銀行門前停著一輛警車。五、比較while, when, as1）as, when 引導(dǎo)短暫性動(dòng)作的動(dòng)詞。 Just as / Just when / When I stopped my car, a man came up to me. 我剎車后，有一個(gè)人向我走來(lái)。 2）當(dāng)從句的動(dòng)作發(fā)生于主句動(dòng)作之前，只能用when 引導(dǎo)這個(gè)從句，不可用as 或 while?！?When you have finished your work, you may have a rest. 干完活后，你可以休息一下。 3）從句表示“隨時(shí)間推移”連詞能用as，不用when 或while。 As the day went on, the weather got worse. 日子一天天過去，天氣越變?cè)綁摹?六、比較until和till 此兩個(gè)連詞意義相同?？隙ㄐ问奖硎镜囊馑际恰白瞿呈轮敝聊硶r(shí)”，動(dòng)詞必須是延續(xù)性的。否定形式表達(dá)的意思是“直至某時(shí)才做某事”。動(dòng)詞為延續(xù)性或非延續(xù)性都可以。正確使用這兩個(gè)連詞的關(guān)鍵之一就在于判斷句中的動(dòng)詞該用肯定式還是否定式。肯定句：I slept until midnight. 我一直睡到半夜時(shí)醒了。 Wait till I call you. 等著我叫你。（在肯定句中可用before代替。例如：Let39。s get in the wheat before the sun sets.）否定句：She didn39。t arrive until 6 o39。clock. 她直到6點(diǎn)才到。 Don39。t get off the bus until it has stopped. 公共汽車停穩(wěn)后再下車。 I didn39。t manage to do it until you had explained how. 直到你教我后，
