when,while和as引导时间状语从句的用法内容摘要:

hile 从句不同的是, as 从句用的一般不用正在进行时,而只是一般过去时。 as 从句一般可以翻 译成“边„„边„„”。 例如: 1. As my mother sang those old songs, tears ran down her cheeks. 当我妈妈唱起那些老歌时,眼泪顺着她的脸颊流了下来。 2. The students took notes as they listened. 学生们边听课边做笔记。 3. As we talked on, he got more and more excited. 我们继续往下谈的时候,他越来越兴奋。 4. The little girls sang as they went. 小姑娘们一边走,一边唱。 5. Just as he caught the ball, there was a tearing sound. 当他抓住球的时候,有一种撕裂的声音。 as 表达的事件,往往只是主句动作发生的背景或条件时, as 只是一个次要的时间说明,不像 while 从句有强调 while 动作本身的意思。 因此, as 常常翻译成“随着„„”之意。 例如: 1. As the time went on, the weather got worse. 随着时间的推移,气候更加糟糕。 2. The atmosphere gets thinner and thinner as the height increases. 随着高度的增加,大气越来越稀薄。 3. As years go by, China is getting stronger and richer. 随着时间一年一年过去,中国变得越来越富强了。 少数情况下,如果强调 动作正在发生, as 从句也可以用正在进行时。 这只能算是特例了。 1. The sad mother sat on the roadside, shouting as she was crying. 伤心的妈妈坐在路边,边哭边叫喊。 2. As we were going out, it began to snow. 正当我们出门时,雪开始下起来。 3. He came in as I was going to bed. 我正要上床睡觉,他进来了。 四、 when, while, as 的互换 如果从句动作和主句动作同时发生,并且从句动作为延续性动词时, when,while, as 可以互换使用。 这种情况下,它们的细微区别恐怕连英、美人自己也说不清了。 1.。
