【题目】阅读理解
In his lowest days when few people bought his records, Taiwan singer Steve Chou lived alone in Canada and did little. One day, he passed by a local CD store and heard a song that greatly attracted him.
"My heart tells me that music is the thing I truly want to do, not for fame(名誉) or money," Chou said. That's how we luckily have such a music genius, who has since then composed(作曲) lots of hits for the pop music charts (排行榜).

【题目】阅读理解
Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time — about eight hours after you wake up — your body temperature goes down. This is what makes you slow down and feel sleepy.
Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps in the middle of the day. This is especially true in warmer climates, where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer(遭受) less from problems such as heart disease. Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it!
If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can also happen if you sleep for too long. If you do not have enough time, try a short nap — even ten minutes of sleep can be helpful.
(1)Why do you sometimes feel sleepy in the early afternoon?
A.Because it's very hot in summer.
B.Because you eat too much for lunch.
C.Because you didn't have a good sleep last night.
D.Because your body temperature goes down at that time.
(2)What advice does the writer give on taking a nap?
A.If your time is limited, a short nap can also help.
B.Only people in warmer climate need to take a nap.
C.You'd better take a nap about an hour after you have lunch.
D.You can sleep as long as you like so that you won't feel tired or sleepy.
(3)What can we learn about "naps" according to the third paragraph?
A.Doctors need to take naps while employers don't.
B.Taking naps is helpful for people's health in spring and summer.
C.If you take naps every day, you'll have less risk of heart disease.
D.All the people in warmer climates take naps in the middle of the day.
(4)What can we infer(推断) from the passage?
A.You will feel less sleepy if you sleep for a long time.
B.Taking a nap whenever you want will do good to your health.
C.If you get up at 6:30 am, you'd better take a nap at about 2:30 pm.
D.Sleeping for eight hours and you'll feel sleepy a short period later.
(5)What would be the best title for the text?
A.Just For a Rest.
B.All For a Nap.
C.A Special Sleep Pattern.
D.Taking Naps in Warmer Climate.
