Input: Consider Input: F: Jack, how have your two sons been doing at school recently? ,M: Don't ask. Mark never start studying and Jason never stop studying. ,F: You are joking. I heard that Jason is likely to be at the top of his class after his exams this year. ,M: Yes, so his teachers say he's been buried in his books every evening for months on end recently. He is hoping to go to Harvard University. ,F: Great. Maybe he'll become a university professor himself in the future. ,M: Maybe, but sometimes I wish he'd go out and enjoy himself for a change. ,F: How about the younger one? ,M: Well, Mark's teachers say he has ability, but he rarely does his best. He does his homework in 10 minutes every day and then rushes out to play football. ,F: But he can make his fortune at football. People can make a lot of money from sports now. ,M: My wife always worries about their future. She wants Mark to study law. I don't believe in forcing them. But I wonder how Mark will progress over the next few years. ,F: Perhaps you, you can have a talk with him now to find out what he's thinking about his studies and future plans.

Input: Consider Input: F: I have been having a lot of trouble managing my time. I always forget my test and homework, due dates and I can never find the right notes I need. I heard that you're really organized. Do you think you could help me? ,M: Sure, I'd be happy to help. First of all, you need to get a planner, like this one. It's a small notebook in calendar where you can write down all the important dates you need to remember. Then you should create some sort of filing system to organize your notes. I use different colored files to keep the papers for my different classes.
(A) F: I’m sorry, I didn’t catch that. Would you mind speaking more slowly? (B) F: Really? You mean you'd not be happy to help me? Oh, we are classmates. (C) F: So, you mean first I don't need to get a planner? Okay, I will take your advice, teacher. (D) F: Oh, you are the considerate classmate. I will take your advice. Thank you.
