我戴观音吊坠十几年了:有offer to do sth, 这个词组吗?

有offer to do sth, 这个词组吗? 是offer sb sth还是 offer sb to do sth? donate one's time to do 还是to doing? How do you offer instruction prefer to do...than to do...有这种说法么？ agree to do sth agree to do sth有吗? 是It's better to do...还是It's better do .....?? What's that got to do with it? it's my intention, not forced to do that. It’s fun to do the impossible.译成中文是?
