8. Learning English 学英语

A: Ralph, do me a favor, will you?
B: That all depends on what it is.
A: This is the proble, I'm still having trouble with my English. The instructor suggests that I ask an American to help me by telling me how he says the things I say which just aren't English. I wanted you to be the American.
B: What good'll it do? You never speak English unless you absolutely have to. I'll help you if you promise to speak noting but English all the time.
A: All right. Maybe I'll do that. It's the only way I'll be able to learn English fast enough, I guess.
