would like和want区别

would like和want用于请求或有关请求的问句中可互换；表示邀请时用would you like?结构，而不能用do you want?结构。如果不是提出请求而只是谈到愿望时，可以随意用would like或want的肯定式、疑问式或否定式；I want要比I would like显得更自信。I want通常不用于表示不可实现的愿望；在过去时中这两种形式的变化不同。

A.在下列情况下,这两个词可以互换使用。

1 用于请求或有关请求的问句中

Customer：I’d like some raspberries,please./I want some raspberries,please．

顾客：请给我拿点儿木莓.

Greengrocer：I’m afraid I haven’t any.Would you like somestrawberries?

蔬菜水果商：对不起,我没有木莓了.您来点草莓怎么样?

Customer：No,I don’t want any strawberries,thanks．

顾客：不,我不想要草莓.（这里不能用 wouldn’t like.）

I would like常常要比 I want更有礼貌。

would you like?要比do you want?更有礼貌,也更殷勤。

would you like?可以含有愿意满足别人的希望的意思.do youwant?则不含有这种意思。因此,与顾客或客人打交道时,通常用 would you like?。

Caller：I’d like to/I want to speak to Mr X,please．

打电话者：我想找X先生说话.

Telephonist：Mr X is out.Would you like to speak to Mr.Y？

话务员：X先生出去了.您跟Y先生说行吗?

2.如果不是提出请求而只是谈到愿望时,可以随意用would like或want的肯定式、疑问式或否定式。它们的意思没有区别,然而,I want要比I would like显得更自信。I want通常不用于表示不可实现的愿望。

I would like to live on Mars．

但愿我能住到火星上去.

B.would like和want在下列用法中不能互换：

1.表示邀请时用 would you like?结构,而不能用do you want?结构：

Would you like a cup of coffee?

您想喝一杯咖啡吗?

Would you like to come to the theatre?

您想来剧院看戏吗?

do you want?用于此处只表示一种询问,不含有邀请的意思。

2 wouldn’t like和 don’t want是有区别的。

don’t want表示没有某种愿望；wouldn’t like表示不喜欢.因此,wouldn’t like不能用来回答邀请或提议,因为在这种回答中wouldn’t like的口气将是不礼貌的.在这里常用don’twant或其他形式来代替wouldn’t like：

—Would you like some more coffee?

—No,I don’t want any more,thanks．/No,thanks．

—您再来点儿咖啡吗?

—不,不要了,

C.在过去时中这两种形式的变化不同。在间接引语中want变为wanted,而would like不起变化：

Tom said,‘I would like/want to see it．’

汤姆说：“我想看看它”。相当于：

Tom said he would like/wanted to see it．

汤姆说他想看看它。

但如果不用间接引语的结构来表示,只能说：Tom wanted tosee it（这里我们不能用would like因为Tom would like to seeit的意思是指现在或将来）。

D would like有两个过去形式：would like+不定式的完成式或would like+不定式/名词/代词。这些形式只能表示未能实现的愿望：

I’d like to have gone skiing./I’d have liked a day’s skiing．

我本想去滑雪的。（但我未能实现我的愿望。）
