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.

Is it because of the cold weather in Northern Europe? ,M: Not exactly. I have a lot of work to do next week. ,F: Well, I'm glad you won't be alone on a holiday. It'll be great to have you celebrate with us. The more the merrier! ,M: Exactly, how many people will be there? ,F: Let's see, my parents, my grandpa, my sister, my brother-in-law, my niece and my two cousins, plus us.
