Power Napping is Good for the I.Q.
Today we hear more and more about the importance of getting enough sleep—about eight hours a night. Sleep can help heal and give energy to both the body and the brain. ____1____ It seems almost certain that the third of our lives that we spend asleep has a great effect on the two-thirds that we are awake. Sleep affects our emotions, memory, focus, and behavior.
Studies show that people in developed countries spend less time asleep and more time at work or commuting. Dr. Karine Spiegel, at the UniversityofChicago, has found that the average length of sleep has gone down from nine hours a night in 1910 to seven-and-a-half hours a night today. However, our bodies cannot function well without enough sleep. ____2____ According to Canadian scientist Dr. Stanley Coren, every hour of lost sleep at night causes us to lose one I.Q. point the next day. For example, when someone gets only five or six hours of sleep each night for a week, the person’s I.Q. could go down 15 points or more. ____3____
Most sleep experts say that humans need at least eight hours of sleep every day, but it should be in two stages: a long sleep at night and a shorter nap in the afternoon. Some companies help their employees follow this advice. ____4____ They say this makes the workers much more efficient.
To study sleep deprivation (not getting enough sleep), scientists use a test called the Multiple Sleep Latency Test (MSLT). During the test, a person stays in a darkened, quiet room during the daytime. Scientists believe that a sleep-deprived person will fall asleep quickly. If it takes ten minutes or longer to fall asleep, the person is probably getting enough sleep.
Scientists have also found that the time of year seems to affect how much sleep we need. ____5____ However, in the summer, people sometimes sleep as little as six hours, without having any problems.

Modern Sun Worshippers
People travel for a lot of reasons. Some tourists go to see battlefields or religious shrines 1. Others are looking for culture, or simply want to have their pictures taken 2 in front of famous places. But most European tourists are looking for a sunny beach to lie on 3.
Northern Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it 4. Residents of cities like London,Copenhagen, andAmsterdamspend a lot of their winter in the dark because the days are so short, and much of the rest of the year in the rain 5. This is the reason theMediterranean 6 has always attracted them. Every summer, more than 25 million people travel to Mediterranean resorts 7 and beaches for their vacation. They all come for the same reason: sun!
The huge crowds mean lots of money for the economies of Mediterranean countries.Italy"s 30,000 hotels are booked solid 8 every summer. And 13 million people camp out on French beaches, parks, and roadsides.Spain"s long sandy coastline attracts more people than anywhere else. 37 million tourists visit yearly, or one tourist for every person living inSpain 9.
But there are signs that the area is getting more tourism than it can handle. TheMediterraneanis already one of the most polluted seas on earth. And with increased tourism ,it"s getting worse. The French can"t figure out 10 what to do with all the garbage left by campers around St. Tropez. And in many places, swimming is dangerous because of pollution.
None of this, however, is spoiling 11 anyone"s fun. TheMediterraneangets more popular every year with tourists. Obviously, they don"t go there for clean water and solitude 12. They tolerate traffic jams 13 and seem to like crowded beaches. They don"t even mind the pollution. No matter how dirty the water is, the coastline still looks beautiful. And as long as 14 the sun shines, it"s still better thanin the cold rain inBerlin,London, orOslo.

1.religious shrine：zōng jiāo 圣殿
2.have their pictures taken：请别人为他们照相
3.But most European tourists are looking for a sunny beach to lie on．但大多数欧洲游客愿意寻找阳光充足的海滩晒日光浴。注意look for和fmd的区别。look for是“找”的过程，常解释为“寻找”,find是“找”的结果，所以常解释为“找到”。不妨体会一下它们的差别：I"ve been looking for my lost watch and haven"t found it yet.
4.Northern Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it．北欧人心甘情愿花大笔金钱，容忍诸多不便去获得阳光，因为阳光对他们来说太难得了。

6.the Mediterranean：地中海地区
7.resorts：指常去的地方，胜地
8.be booked solid：全部客满
9.37 million tourists visit yearly ,or one tourist for every person living in Spain．每年有3 700多万游客，换句话说，旅游者与西班牙居民人数相当，即为1:1。
