would like to 与want to的区别

would like to 语气委婉 最常用于用餐时回应他人
want to语气直接 与feel like doing相近
另外be willing to do不常用 也是愿意做某事的意思 很少出现在口语对话中

简单说
would like to语气委婉常用在餐厅吃饭场合
want to表意愿可用范围广

would like to do sth是愿意作某事表示愿意乐意可以等于Be will to do sth
而want to do sth 式表示想要做某事表达一种想法,前者程度更深
would like和 want
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（但这里不使用 would not like,参见下面B1）：
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
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.）

你好
would like to有愿意的意思
wantto只是想要做某事 不过want 跟feel like跟相近
