听力原文： Nothing can buy a better night's sleep. Although it sounds silly, it was the first thing that crossed my mind when I awoke. I truly appreciated my happy rest. It was like a gift from heaven. Interesting to think that Bill Gates, or any rich men you can mention, really couldn't have had a more satisfying and grateful night of sleety--the best that money can't buy. That started me thinking of other pleasures that cost nothing or very little and that are often taken for granted, like a drink of cold water on a hot day when you're really thirsty, or a warm relaxing bath when you're extremely tired or mentally exhausted. Remember your first real kiss--can you put a price tag on that? Or the companionship of a faithful and loving pet or the clean, fresh smell of mountain air? There's an old song, 'the Best Things in Life Are Free.' Did you ever eat a meal that not only filled your stomach and satisfied all your tastes, but refreshed your soul? Ever spend a winter's evening in the company of good friends? What could be better than listening to your favorite music or watching a good movie? Or sharing the beauty of a sunset with a loved one? These are quite delightful and delicate pleasures. I hope this doesn't sound too ridiculous in today's rough, loud world. I hope the new generation can appreciate some of these things.(33)A．The writer enjoys sleeping very much.B．Bill Gates does not know how to enjoy himself.C．The writer doesn't like money at all.D．Mental well-being is the most important thing. 点击查看答案
