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．
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．
Tom said he would like/wanted to see it．
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）.
