One of these is a condition called hypoxia (缺氧症). It results from a lack of oxygen to the brain. Experts say the body begins losing oxygen minutes after an airplane leaves the ground. The air pressure in a plane during flight is lower than at sea level. This makes it more difficult for the body to effectively use the same amount of oxygen as it would on the ground. Fewer oxygen molecules （分子） cross the tissues (组织) in the lungs and reach the bloodstream.
The result is a five to twenty percent drop in the amount of oxygen in the blood. This reduces the amount of oxygen that reaches the organs of the body.
One effect of this lack of oxygen to the brain is a headache. When this happens, the heart attempts to fix the situation by beating harder and faster. This can make the traveler feel tired.
These signs of hypoxia are not dangerous in a healthy person. But a drop in oxygen level can cause a health emergency in people with heart or lung problems. They might lose consciousness or even suffer a heart attack.
Experts say that smoking cigarettes and drinking alcoholic liquids also reduce the body’s ability to use oxygen. So they suggest that people not drink alcohol or smoke cigarettes either before or during a flight. They also say persons with heart or lung problems should seek advice from their doctors before flying.

| A．warn people in airplanes of possible dangers |

| C．explain the causes and effects of hypoxia |
| D．advise people not to smoke or drink alcohol |

These days more and more people are taking their holidays late in the year and for good reasons. Holidays in autumn can be cheaper, the resorts are less crowded and the weather isn’t as extreme as it is in the summer. So, where are the best places to go? Here are our top tips.
Sardinia (in Italy) has an average temperature of 27℃ in September. It also has “Autunno in Barbagia” (Autumn in Barbagia) a series of festivals that take place in 27 villages in Barbagia, a mountainous region of inland Sardinia. The festivals continue from September to December, so there’s always something happening. There are street markets, craft workshops and there’s lots of eating and drinking (This is Italy, after all).
Dubrovnik Croatia has become very popular in summer but it’s quieter and more pleasant once the crowds have left. The weather is still warm but less humid. You can take a ferry to the popular beaches on the islands of Sunj and enjoy it with locals.
Dahab Egypt, is extremely hot in the summer with temperatures up to 38℃. However, the autumn is cooler while the sea is still warm. This makes Dahab the perfect place for snorkeling and windsurfing. There are also interesting historical sites to visit such as the Coloured Canyon, with its dramatic rock formations, and St Catherine’s Monastery, at the foot of Mount Sinai.
Kas is a relaxed fishing village on the Lycian coast in southern Turkey. There are plenty of things to do and the temperature has dropped (so you can actually enjoy doing them!) Kas is a good place to stay if you want to walk part of the Lycian way: a long-distance footpath that stretches for 500km from Fethiye to Antalya through the ancient land of Lycia. There are also watersports, of course. The best time to go diving is supposed to be after the first rains of autumn (usually between late September and early October) when the fish become most active.
Marrakech Morocco is another good destination. The city itself is a fascinating place to spend a few days. When you have had enough of that, go to Tigmi, a beautiful hill town about 20 kilometers away. There’s a hammam (a Turkish bath) and a large heated pool, which makes it the perfect place to relax.
Wherever you go this autumn – have fun!

“Have a nice day. Next!”This version of the expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out the door. The words come out in the same tone（腔调）with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else’s is the management’s attempt to increase business.
The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression saves us when we don’t know what to say “oh, you may have a tooth out? I’m terribly sorry, but have a nice day.”
The expression can be pleasant. If a stranger says “Have a nice day” to you, you may find it heart-warming because someone you don’t know has tried to be nice to you.
Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that it is a little uninteresting. The salesgirl, the waitress, the teacher, and all the countless others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it’s nice to know they care enough to pretend they care when they really don’t care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.

An attraction of sport programs for the major U. S. media companies is that events are often held on Saturday and Sunday afternoons—the slowest time periods of the week for general television viewing. Sport events are the most popular weekend programs, especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at relatively high prices during what normally would be dead time for programming.
Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of major corporations realize that sports attract made viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers, cars and life insurance.
Golf and tennis are special cases for television programming. These sports attract few viewers, and the ratings(收视率)are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States, to certain advertisers. It is made up of people from the highest income groups in the United States, including many lawyers and business managers. This is why television reporting of golf and tennis is sponsored by companies selling high-priced cars, business and personal computer, and holiday trips. This is also why the networks continue to carry these programs regardless of low ratings. Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions to buy thousands of “company cars” and computer, with such viewers, these programs don’t need high ratings to stay on the air.

The Mona Lisa, painted by the Italian, Leonardo da Vinci, has been on show for many years in Paris. Now a row of white spots on the neck have been “seen”. They are said to be the remains (痕迹) of a necklace which the artist later painted over.
The painting will be examined further by using infrared scanning (红外线扫描) techniques. Laser (激光) technology can be used to show what lies directly under the surface of the finished work, too. This will help us to understand how the artist drew the picture: Did he begin with a quick-made drawing or have second thoughts as he painted the picture?
This kind of knowledge will show us the famous artist at work. It may also help to explain Mona Lisa’s smile, which has puzzled art lovers for centuries.
