Some people say that the best way to reduce the size of your waist is to do stomach exercise. Many people believe that when specific muscles are exercised, the fatty tissues (组织) in the immediate area are burned up. The truth is that exercise burns fat from all over the body and not from one specific area. Of course, if you reduce the fat throughout your body, you will certainly see results around your waist too.

Some people believe that you need to exercise twice a week in order to keep a sufficient level of physical fitness. However, studies directed by American scientists show that unexercised muscles lose their strength very quickly. Within 48 to 72 hours, you must use the muscles again to reestablish (重建) the good physical effects. And what does that mean to you? American scientists concluded that while daily exercise is most helpful, exercising every other day or three days a week will keep a sufficient level of physical fitness.

Is it true that you burn more calories running one mile than walking the same distance? The answer is no. The truth is that you use the same amount of energy whether you walk or run the mile, since in both cases you are moving the same weight the same distance. The speed does not matter. Of course, if you run rather than walk for 30 minutes, you will cover more distance, and therefore burn more calories.

If your breathing doesn’t return to normal within 5 minutes after you finish exercising, you have exercised too much. Five minutes or so after exercising, your breathing should be normal, your heart shouldn’t be beating loudly, and you shouldn’t be tired.

Is it true that cats have nine lives? One 4-year-old American cat named Sugar definitely seems to have more than one. Sugar fell from the 19th floor of her owner’s home in Boston last month and was only hurt a little on her chest.
“This story isn’t much of a surprise,” said Jake Socha, a scientist at Virginia Tech University, US, in an interview with the BBC. “There have been lots of records of these cats surviving.”
Back in 1987, scientists studied 132 cats. All of them had been brought to a vet’s clinic in New York after falling from tall buildings. Around 90 percent of these cats were alive after their fall and only 37 percent had been seriously injured.
“Being able to survive falls is a critical thing for animals that live in trees, and cats are one of them,” said Socha.
Cats have developed special body structures to survive accidental falls. Their legs are muscular. This can protect their bones from breaking, Professor Andrew Biewener from Harvard University told the BBC. Cats can also spread out their legs like a parachute to reduce their falling speed, he said.
The strange part, according to scientists, is that cats have a better chance of survival if they fall from higher than seven stories. This is because cats have a good sense of which way is down. They can twist their bodies as they fall to make sure they land on their feet. A higher fall means more time for the cat to change its body position.
However, you should not throw your cat out of the window to see how this works. Most pet cats are overweight nowadays. They are not fit enough to change their position in midair, warned Steve Dale, an American cat behavior scientist.
“This cat (Sugar) was lucky,” Dale said. In fact, most cats would suffer serious lung damage, a broken leg or a broken jaw or teeth damage, he said.

C．Challenging.

D．Serious.

【小题3】Why can cats survive falls according to the article?
a. They have a hidden parachute in their bodies.
b. Their legs have developed in a way that protects their bones from breaking.
c. They can land on their feet.
d. They can twist their bodies to reduce the speed at which they are falling.

A．a, b

B．b, c

C．c, d

D．b, d

【小题4】Which of the following statements is TRUE?

A．A pet cat that falls out of a tall building is not really at risk.

B．Sugar was lucky that she was only injured in the leg.

C．Cats are confused as to which way is down when they are in midair.

D．A cat that falls from the fourth story of a building is more likely to die than one that falls from the 10th story.

Most people think that the older you get, the harder it is to learn a new language. That is, they believe that children learn more easily and efficiently than adults. Thus, at some point in our lives, maybe around age 12 or 13, we lose the ability to learn languages well. Is this idea a fact or myth(悬念)？

Is it true that children learn a foreign language more efficiently than adults? On the contrary, research studies suggest that the opposite may be true. One report, on 2,000 Danish children studying Swedish, concluded that the teenagers learned more, in less time, than the younger children. Another report, on Americans learning Russian, showed a direct improvement of ability over the age range tested; that is, the ability to learn increased as the age increased, from childhood to adulthood.

There are several possible explanations for these findings. For one thing, adults know more about the world and therefore are able to understand meanings more easily than children. Moreover, adults can use logical(逻辑的) thinking to help themselves see patterns in the language. Finally, adults have more self-discipline (self-control) than children.

All in all, it seems that the common idea that children are better language learners than adults may not be a fact, but a myth.

1.The main idea of the passage is that         .

A．teenagers are more difficult to teach

B．Danish teenagers can learn Swedish faster than younger children

C．adults are more logical than children

D．the ability to learn languages increases with age

2. If most people’s idea of learning languages is true, people may lose ability to learn languages well         .

A．at an early age	B．when they reach their twenties
C．at an old age	D．after they become young men

3.According to the passage, teenagers can learn a foreign language __________ than younger children.

A．harder

B．more efficiently

C．more slowly

D．more carefully

4.The reason why adults understand meanings more easily than children is that         .
