A: What are you watching?

B: A football game. Packers are playing the Chiefs.

A: I never understood this game.

B: It's not that hard. If you watch a couple of games, you'll start to understand it.

A: Do you watch a lot of football?

B: I like the Packers, so I watch all their games.

A: Did you play football before?

B: Only in high school. I was too small to play for college.

A: What position did you play?

B: I was the corner back（角卫）.

A: Is that the main guy in offense?

B: No. That's the quarterback（四分卫）. The corner back is a defensive player covering passing plays and outside running plays.

A: I see. Do you think it is more fun than baseball?

B: It's hard to compare the two because they're so different. I like both baseball and football. How about you? You like baseball a lot?

A: Yeah. I'm a big baseball fan.

B: Baseball is fun, but you should also learn football. I'll explain as we watch.

A: Cool.
