英语听力文摘 English Digest 132、当香蕉变坏

　　Y: So Don, yesterday I was walking down the produce aisle¹ when I saw it--long, ripe,yellow. The perfect banana. It really looked delicious and I had to have it. I took it  home and hung it on a banana hanger². The very next morning, it developed nasty brown spots.
D: And you're wondering what gives.
Y: Right. It was a good banana yesterday. What happened?
D: It's no mystery, Yael. Those spots are a natural part of the ripening⁴ process. You see, just like all fresh produce, your bananas are alive.They're taking in oxygen to   help them convert sugars into energy, and releasing carbon dioxide. This process is called respiration⁵.
Y: I don't know, Don, this banana looks dead to me.
D: Now, the quicker a fruit or vegetable respires, the quicker it ripens⁶. For most fruits,the respiration rate slows down after the initial growth stage and the fruit ripens slowly. The growth and ripening process of bananas, however, is different. Although  at first the banana's respiration slows down too, when it's ready to ripen³, the   banana's pulp⁷ releases a chemical that increases respiration. This converts the starches⁸ in the banana to sugars and gives it its fabulous⁹ taste. And you know how good bananas taste!
Y: Watch it--you're drooling. But what does all this ripening have to do with spots?
D: Well, with all this respiration, the banana eventually processes all the starches available. And that's when it begins to die. Those brown spots are rot and decay.
Y: Poor thing. It just ran out of fuel.
D: Yeah, it's never easy seeing a good banana go bad.
