区分would与used to的差别

Would与used to都可用来表示过去经常性或习惯性的动作，常常可以换用。接下来，小编给大家准备了区分would与used to的差别,欢迎大家参考与借鉴。

(1)When we were boys we used1 to/would go swimming every summer.

小时候，每到夏天我们都要去游泳。

(2)He used to/would spend every penny2 he earned on books.

过去，他通常把挣来的钱全花在买书上。

Would与used to都不能用来表示动作发生的具体频度或具体的一段时间。例如，不能说：

(3)I would/used to go to France six times.

(4)He used to live in Africa for twenty years.

上两句应改成：

(5)I went to France six times. 我去过法国6次。

(6)He lived in Africa for twenty years. 他在非洲住过20年。

Would与used to的区别主要有以下几点：

a. Used to可指过去的状态或情况，would则不能。如：

(7)School children used to know the story of how Abraham Lincoln walked five miles to return a penny he'd overcharged a customer.(不能用would)

过去，学校的孩子们都知道亚伯拉罕·林肯怎样步行5英里退还多收顾客1便士的故事。

(8)Yet，he cannot but remember China as it used to be.然而，他不会不记得旧日的中国(不能用would)。

b. Would表示反复发生的动作。如果某一动作没有反复性，就不能用 would，只能用 used to。例如：

(9) And from that day on， as soon as the table was cleared and the dishes were gone. Mother would disappear3 into her sewing4 room to practice.

从那天起，只要碗盘撤掉、饭桌一清理干净，妈妈就马上躲进做针线活的房间练习起来。(具有反复性)

(10)I used to live in Beijing. 我过去住在北京。(没有反复性)

c. Used to表示过去经常性或习惯性的动作或状态现在已经结束，would则表示有可能再发生。如：

(11)People used to believe that the earth was flat.

过去，人们总以为地球是扁平的。(现在已不再这样认为)

(12)He would go to the park as soon as he was free.

过去，他一有空就去公园。(现在有可能再去)

注意：used to的否定式和疑问句:

(13)过去我不喜欢歌剧。

I used not to like opera.

I usedn't to like opera.

I didn't use to like opera.

(14)过去你喜欢歌剧吗?

used you to like opera?

Did you use to like opera?

(15)Didn't you use to like opera? 你过去不喜欢歌剧吗?

(16)You used to like opera, didn't you? 你过去喜欢歌剧，是吗?

(17)There used to be a church here， usedn't there? 过去这里有座教堂，是不是?

　　扩展：小议but的用法

在英语中，but除了最常用的表示转折关系外还有以下几种常见用法：

一、but用法连词，表示让步关系，意思是“除非，要不是”，常与that一起构成but that, 相当于""。 例如：I would1 have failed2 but that your helped me.要不是你们帮助我，我就会失败。

二、but用作连词，放在否定词或疑问词之后，作从属关系，表示否定意义，可相当于that not. 例如： Never a month passed but she writes to her parents. 她没有一个月不给她双亲写信。

三、but用于否定词加doubt,question,deny等到之后，没有实在意义，只相当于关系连词that. 例如： There"s no doubt3 but he is a thief4.毫无疑问，他是一个贼。

四、but用作介词，表示“除了”意义，相当于besides,except.例如：No one knows him but she. 除了她，没有人认识他。

五、but用作副词，相当于only, 常译为“只不过，仅仅”。例如：He finished5 his homework but ten minutes ago.他十分钟前刚完成作业。

六、buy用作代词，表示从属关系，在否定句中常相当于who/that not.例如：There is no one but likes to help him. 大家都愿帮他。
