W: You don't look happy. What's up?
M: It's the computer assignment. John and I teamed up to do the project together. But so far we've done only half it.
W: Well, you'd better hurry up.
M: I know. But actually, John is not doing anything. I don't know how to say it to him. He's having problems with his parents and has been quite upset these days.
W: But it's supposed to be his work as much as yours. I suggest you talk to him. And let him know that he should share the work.
M: Yes. I think I'll share the work.

答案解析：
(1) 正確答案為C。根據John is not doing anything. I don't know how to say it to him.約翰什么都不做，我不知道要怎么跟他說。可知，二人在談論如何讓約翰參與作業，因此C項正確。
(2) 正確答案為A。根據He's having problems with his parents and has been quite upset these days.他和他父母之間出現了問題，他這些天都很沮喪。可知，約翰沮喪的原因是因為與父母鬧了矛盾，因此A項正確。
