听力原文：M: Hi, Janet, going to the football game today？
W: No. I'm planning to watch it on television.
M: Why is that？ Don't you have enough money to last till the end of the month？
W: Money's not the problem, I find it easier to follow football on television than in the stadium. When I see the game in person, I feel as if I'm too far away from the action. And I always lose track of the ball.
M: I know just what you mean. Besides, on television the new cameras they use give you super views of all the plays. But there's always so much excitement. People are cheering and shouting when you're there in person. People are very enthusiastic, and I end up cheering along with everyone.
W: You're right there. But I'd like to know exactly what I'm screaming for. And if I can't even see who has the ball, I can't get very excited. So I really prefer watching it on television.
M: I see your point. Well, enjoy the game.
W: You, too.
