6 to 12 years old need an average (平均) of 10 to 12 hours of sleep. Teenagers need 9 to 10 hours of sleep.
An adult needs an average of 7 to 8 hours a night. There are some people who need only 3 hours of sleep.
Others need 10 hours of sleep. After the age of 50, the average sleep time goes down to 6.5 hours a night.
We need less sleep as we get older.
About one in three Americans has a problem with sleep. Many of these people cannot fall asleep. The
name of this problem is insomnia. Some people say, "I didn"t sleep all night." But that"s not really true.

awake (醒着), so they think they were awake all night.
This is not a new problem. Many famous people in history had insomnia. Some of these people had
special ideas to make them sleep. Benjamin Franklin had four beds. He moved from one to the other to fall
asleep. Mark Twain had a different way. He lay on his side across the end of the bed!

Do you feel sleepy, like something is weighing down on your head? Do you feel forgetful? Do you
sometimes feel uncomfortable up and down your neck and lower back, and you can"t explain why? Do you get
sick often? It could be radiation (辐射) from your computer causing it. If you spend three hours or more a day
in front of a computer, (and at this point, who doesn"t?) you are more easily harmed by these hazards (危害).
We have got so used to using computers that we don"t often think of them as dangerous sources (来源)
of harmful (有害的) radiation. A safe amount radiation is 25 V/m (Volts/meter). Do you want to guess how
much our personal computers give off?
★ Keyboard: 1000 V/m ★ Mouse: 450V/m ★ Monitor: 218 V/m
★ CPU: 170V/m ★ Notebook computers: 2, 500 V/m
Ways to Protect Yourself from Harmful Computer Radiation:
1. Decorate your desk with cactus (仙人掌) plants, they take in radiation.
2. Drink two to three cups of green tea a day and eat an orange daily. The vitamins in tea leaves and
oranges protect us from radiation and keep our eyes healthy as well.
3. Use a screen filter (过滤器) for your monitor.
4. Avoid having metal objects nearby on your desk.
5. Put the back of the computer to the wall. Most of the radiation comes off the back.
6. Keep your monitor at least 50cm away from your face.
7. Keep your computer rooms ventilated (空气流通的).
8. Eat healthily-especially fruits and vegetables.
9. Don"t fall asleep on your computer. Turn it off if you have to rest nearby. The ways above are useful,
why not have a try at once?
A. 根据短文内容简要回答问题。
1. Which is safer, using a desk computer or a notebook computer?
_______________________________________________________________________
2. Which of the nine ways mentions diets?
_______________________________________________________________________
B. 将短文中划线的句子译成汉语。
3. _______________________________________________________________________
4. _______________________________________________________________________
5. Which is the best title of this passage? ________

First, several 1 talk about the new car and any good ideas that they have. Then they sit down at their
computers and 2 many sketches. The best two or three drawings are chosen and then more detailed
drawings of 3 are developed on the computer. You can change the size, shape or color of any part on the
computer to see 4 the car would look and then you can choose the best design.
Both the inside and the outside of the car have to be designed. Part of the inside of the car is 5 so that
the designers can sit in it. They can feel if there is enough 6 inside and if they can reach 7 . Then some
cars are built-there are more than 15, 000 parts of a car to 8 .
When everything is known to be 9 . the cars are made in the factory. Again, computers are used to
make sure that all the parts are 10 as they are needed. The factory usually stays open all through the night so
that the car production never stops.

| Why do you think people who live in some hot countries eat very spicy (辛辣的) food? Is it because the spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked hot food, or is there some connection between spices and healthy food? Researchers from Cornell University think that it is because spice plants have some important chemicals (化学物质). These chemicals can kill bacteria (细菌) which spoil food. "Most common spices can kill 75 to 100 percent of the bacteria in food," explains one of the scientists. The bacteria grow more easily and spoil food more quickly at higher temperatures. For this reason, it is more difficult to keep food from spoiling in hot climates. Do you like your food spicy? Your answer probably tells something about the country you come from. If you like spicy food, it is possible that hundreds of years ago, when there were no fridges, people in your country started using spices to keep the food from spoiling. The traditional spicy dishes helped those people to live longer, healthier lives. Today, in a time of fridges, the spices just make the food taste good. |
