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.

From this point of view, I also think online stores will not replace high street stores. (D) M: So you think people don't need to touch things before they sale them?
