Maybe you can find what you can do under the agreement.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: Yeah, the unfair agreement is annoying. Can you believe that I don't even have air-conditioning or fridge?

I will see how I can deal with the poor electric equipment, or I'll definitely move out soon.

Input: Consider Input: M: Lily, I can't catch up with the English teacher very well. ,F: What's the problem? ,M: You are quite good at English.

What's that? ,F: This kind of school is good at helping people to improve their English. ,M: Is that different from our school's English course? ,F: Yes.

How good can my English get there? ,F: You see how well I am doing. I studied there, too. ,M: Alright. I'll tell my father about it.
(A) F: I am really sorry, I did not catch that. Would you slow down, please? (B) F: Yes. I think you should go to the English schools. It's really helpful.
