Here are some of the most common causes of fatigue, and what you can do about them.
Inadequate Sleep. If you don’t get enough sleep you’ll be tired but it’s rare that busy people get enough sleep. When there aren’t enough hours in the day to do everything, something has to give, and that’s usually sleep. Don’t fool yourself that you can get by on five or six hours of sleep a night. Most people need at least eight hours and some even more.
Hormone Imbalances. Thyroid disease is extremely common today, especially among young women and the elderly. As common as thyroid disease is, its symptoms are so similar to so many other ailments that it often goes unnoticed by both doctors and patients. If you’re suffering from fatigue, get your thyroid hormone levels checked.
Food Allergies. You may be allergic to common foods like dairy, eggs, nuts, wheat, corn, chocolate, or coffee. If you suffer from coughing or wheezing, digestive problems, headaches, muscle aches or joint pain, itching and skin problems, in addition to fatigue, try cutting out each of these foods for a week to see if you feel better without it. Also, don’t eat excessive amounts of any particular food during any one day.
Environmental Toxins. Fatigue may result from our polluted environment. If, in addition to fatigue, you suffer from headaches, allergies or respiratory problems, you may be absorbing airborne toxins. Check the ventilation system in your home and office. Buy houseplants, air filters, and water filters for your home. If you’re working in a “sick” building you may have to look for another job.
Couch Potato Syndrome. Fifty percent of depression and fatigue can be caused by inactivity. For an energy boost, do anything that gets you moving for 20 to 30 minutes a day.
Anemia. Anemia can be a hidden disease in women. If you’re tired for no known reason, have your total iron count taken. Sometimes, even though your blood count may show a normal level of red blood cells, you may still be deficient in iron. If your iron count is low, you may need supplements.
Cigarette Smoking. Cigarettes are an enormous energy drain. They rob the body’s cells of oxygen and produce carbon monoxide poisoning.
Too Much Coffee. If you drink a lot of coffee in the effort to beat fatigue, in the long run you’ll be even more tired. Coffee gives you a temporary lift at the cost of long-term energy.
Poor Nutrition. The typical American diet, high in refined foods and animal fat, supplies inadequate nutrients and drains energy. Switch to a diet low in animal protein and saturated fat and high in fruits, vegetables, grains and beans. Cut out highly processed foods. Take vitamins.

Dinner parties are out of date. Alumni (毕业生,校友) album are old-fashioned. School leaving is taking on a new turn：it is going online! Graduating students at Qinghua University are saving all their joys and sorrows from university on a CD. Some are setting up their alumni records online, such as Chinaren.com and 5406.net. With computer usage and Internet access becoming even more popular, students are throwing away the traditional graduation book. Instead they are using alumni books online, in CDs or disks, electrolyzing(电解) their graduation in the e-age.
"It is much easier and safer to save." Xu Ziguo, a civil-engineer-major at Qinghua University said. Like his class, most of Qinghua's to-be graduates are using the CD alumni records and online association. Xu said CD records can save more than the actual books. Photos and videos on school activities and normal campus life, and messages may be all included in the thin plastic with the help of a CD-Writer. "Everything is so lively when I watch it, just like what is happening on campus," Xu said. Another student at the Renmin University of China, Lu Yangzhen said her class saved all the memorable messages on a disk. They use a common chat room online to communicate after graduation. Many classes will keep their homepages on campus for future communication, Lu said.
Dotcom companies are also seizing the opportunity to get more clicks. Chinaren.com said it provided improved services for the users. One service is to send group emails, meaning if a user sends an email to one address, all his or her classmates can get it at the same time. But what if the Dotcom company breaks down one day? Xu said they had left a "backup". That is to use the old way with a person working as the liaison.

第三部分 阅读理解（共20小题。 每小题2分，满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
Drying food is a simple, low-cost way to keep food safe for eating. Drying removes water that small organisms use to break down food into other substances. Some of these substances may be poisonous to humans.
A device that uses the sun is a good way to dry food. There are several kinds of solar dryers. The easiest to build is called the direct dryer. The sun shines directly on the food being dried. The direct dryer is a box with holes in it so that air can enter and leave the box. It has a cover made of clear glass or plastic. When the sun shines into the box, heat is produced. The heat is trapped inside the box and cannot escape back through the cover. The heat dries the food.
The solar dryer works better if the sides of the box are black. This is because dark colors hold heat while light colors reflect it. One way to make the sides black is to use wood that has been blackened by fire.
If you use black paint instead, be sure the paint contains no lead. Lead is poisonous to people, especially children.
The box can be made of almost any material such as wood, concrete or sheet metal. The dryer should be two meters long, one meter wide and twenty-three to thirty centimeters deep. The sides and bottom should have additional material, called insulation, to keep the heat from escaping.
The surface on which the food is placed should permit air to enter from below and pass through to the food. A surface made of wires with small square openings works very well. You should use wire with the largest openings or squares that do not allow the food to fall through. Air that comes in from below the wire surface will also carry away water evaporated from the food as it dries.
A direct dryer will dry most vegetables in two-and-one-half to four hours at temperatures from forty-three to sixty-three degrees Celsius. Fruits take longer, from four to six hours at the same temperatures.
51.Solar food drying is fast, safe and low-cost. It is also healthy because nutrients such as vitamin C are kept in the food. Solar dried food also tastes and looks good.
51.In which way will the food be fried quickly?
A.Let the sun shine directly on the food.
B.Make the sides of the box black.
C.Make wood be the sides of the box.
D.The box must be made of blackened wood.
52.What does the underlined word “evaporate” in the 6th paragraph mean?
A. sink into B. change into gas or steam C. flow away D. flow into
53.According to the text., which of the following statements is true?
A.Water in the food may cause poisonous substances.
B.The sun shines into the box and be trapped.
C.Dark colours hold heat better than light colours.
D.It takes longer for vegetable to be fried.
