Passage One

Questions 17 to 19 are based on the passage you have just heard.

听力原文：

Passage One I first met Joe Gans when we were both nine years old, which is probably the

only reason he’s one of my best friends. If I had first met Joe as a freshman in high

school, we wouldn’t even have had the chance to get to know each other. Joe is a day

student, but I am a boarding student. We haven’t been in the same classes, sports, or

extracurricular activities.

Nonetheless, I spend nearly every weekend at his house and we talk on the phone every

night. This is not to say that we would not have been compatible if we had first met in our

freshman year. Rather, we would not have been likely to spend enough time getting to know

each other due to the lack of immediately visible mutual interests. In fact, to be honest,

I struggle even now to think of things we have in common. But maybe that’s what makes us

enjoy each other’s company so much. When I look at my friendship with Joe, I wonder how

many people I’ve known whom I never disliked, but simply didn’t take the time to get to

know. Thanks to Joe, I have realized how little basis there is for the social divisions

that exist in every community. Since this realization, I have begun to make an even more

determined effort to find friends in unexpected people and places.
