.would like 后加to do?这个短语怎么用?

would like to do是固定搭配
would的用法如下
1）would like； Would like to do = want to 想要,为固定搭配.
Would you like to go with me?
2）Will you…?　Would you like…?表示肯定含义的请求劝说时,疑问句中一般用some,而不是any.
Would you like some cake?
3）否定结构中用will,一般不用would,won't you是一种委婉语气.
Won't you sit down?

sb. would like to do sth. 意思就是某人想去做某事，跟sb. want to do sth. 差不多
如 I would like to go out. =I'd like to go out. = I want to go out
