　　On Sundays he would get up early and go fishing.

　　2) Will/would you please do...,Would you like to do...,Would you mind doing...

　　都表示建议、询问、请求等。

　　【例如】

　　Will you please pass me a cup of tea?

　　Would you like me to give you a hand?

　　This box is too heavy, ____give me a hand? (CET-4 1998,1)

　　A) would you mind

　　B) would you please

　　C) will you like to

　　四个结构中，would you mind接动名词；would you please接动词原形；

　　will you like to不是正确结构；will you please to也不是正确结构，因此答案为B。
