题目内容

When you run, you put force that is equal to three times your body weight on your feet. The human foot contains twenty muscles（肌肉）. This means that there is a lot that can go wrong when you run.

Most sports have some kind of running or jumping. So experts（专家） at many shoe companies work hard to design good sport shoes. First, a designer enters a plan for a shoe into a computer. Engineers then improve the design. A second computer designs a model for the shoe. Then a few pairs are made. Next, the shoe is tested.

Different kinds of sports shoes are made for different uses. Some are made to help marathon runners save energy during a race. Some are made for the stop-and-go kind of running tennis players. But all sport shoes have one thing in common: they are designed to help people’s feet comfortable during sports. Today, nearly every sport has its own special shoe designed for just the kind of running that sport requires.

1.The first in making a new shoe is to ______.

A．make a computer B．design a shoe model

C．test several pairs D．put a design plan into a computer

2.Why are good sport shoes welcome to people?

A．Because they help to change body weight.

B．Because they help to develop leg muscles.

C．Because they are both good and cheap.

D．Because they are comfortable to wear.

3.What is NOT talked about in the passage?

A．The number of the bones of a human muscle.

B．The effect of shoes upon sports.

C．The materials （材料）of sport shoes.

D．The design for a shoe model.

4.Different kinds of sport shoes _______.

Microwaves may be great at warming up food, but what about warming people?

Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Buffler of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.

To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 milliwatts per square centimeter (mw. /sq.cm.); a satisfactory feeling of warmth occurs between 35 and 50 mw./sq.cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw./sq.cm. And a frozen meat pie in your microwave oven receives about 1000 mw./sq. cm.

In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwaves oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)

While it might be some time before homeowners are comfortable enough with the idea to set up whole body microwave heaters in houses, Buffler says microwaves may attract livestock farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.

Which of the following can tell the main idea of the passage?

A. A new heating system. B. A new microwave oven.

C. A popular technique. D. The magnetron.

The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about ____.

A. 20 mw. / sq. cm. B. 40 mw. / sq. cm.

C. 60 mw. / sq. cm. D. 85 mw. / sq. cm.

According to paragraph 4, which of the following fills the room with low-power microwaves?

A. The magnetron. B. The motion detector.

C. The microwave oven. D. The radiation-absorbing chemical.

Which of the following statements about microwave heaters would Buffler most probably agree with?

A. Microwave heaters will soon be widely used by homeowners.

B. Microwave heaters sometimes make people feel uncomfortable.

C. Microwave heaters will be probably first used by livestock farmers to protect their lambs in winter.

D. Microwave heaters cannot be accepted by the public because they are somewhat unsafe.

I know what you’re thinking : pizza （比萨饼）? For breakfast? But the truth is that you can have last night’s leftovers in the a. m. if you want to.

I know lots of women who skip breakfast （不吃早餐） , and they have a ton of different excuses for doing it . Some say they don’t have time. others think they’re “saving” calories （卡路里）, still others just don’t like breakfast food .

But the bottom line is that eating in the morning is very important when you’re trying to lose weight. “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking , R , D , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece. 21 Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southem California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.

So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it…you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.

The word “leftovers” in Paragraph 1 probably means__________.

A.food remaining after a meal B. things left undone

C. meals made of vegetables D. pizza topped with fruit

What can we infer from the text?

A. Working women usually have breakfast in a hurry.

B. Many people have wrong ideas about breakfast.

C. There are some easy ways of cooking a meal.

D. Eating vegetables helps save energy.

According to the last paragraph, it is important to____________.

A. eat something for breakfast B. be careful about what you eat

C. heat up food before eating it D. eat calorie-controlled food

The text is written mainly for those_____________.

A. who go to work early B. who want to lose weight

C. who stay up late D. who eat before sleep
