For years, experts have been encouraging people to exercise, using steps as simple as taking the stairs instead of a lift and walking to work, where possible. A recent study bolsters this advice — it shows that frequent active exercise throughout the day can have great health benefits.

The study, published in the magazine Preventive Medicine, found that just 2 minutes of stair-climbing several times a day can lower total cholesterol(胆固醇), raise HDL (“good”) cholesterol and improve the heartbeat in young women who do not have much activity during the day.“such improvements may have important effects on the health of women, since, like cigarette smoking, poor fitness have been shown to be a high risk for heart disease and death in women,”said Dr.Colin Boreham with the University of Ulster in Belfast, Ireland and the fellow researchers of this study group. Furthermore, improvements in total cholesterol levels achieved in the study could cut the rate of heart disease in women by a third, they noted.

The team of researchers from Britain studied 12 women between 18-22 years old, before and after the exercise program. The women used a public staircase for about 2 minutes a day for 5 days a week. Compared with a group of 10 women who did not take part in the stair-climbing program, the women who climbed stairs showed marked improvements in health and fitness levels after 7 weeks. However, they did not show any signs of weight loss.“A short-term stair-climbing program can give great health benefits to young women. Stair-climbing may be a particularly suitable way of combining exercise with an individual’s daily lifestyle,”they pointed out.

Experts advise visiting your doctor before beginning a new exercise program.

For years we have been told that encouraging a child’s self-respect is important to his or her success in life. But child experts are now learning that too much praise can lead to the opposite effect. Praise-aholic kids who expect it at every turn may become teens who seek the same kind of approval from their friends when asked if they want to go in the backseat of the car.

The implication (含义) of saying “You are the prettiest girl in class,” or talking about the goals she scored but not her overall effort, is that you love her only when she looks the best, scores the highest, achieves the most. And this carries over to the classroom.

Social psychologist Carol Dweck, PhD, tested the effects of over praise on 400 fifth graders while she was at Columbia University. She found that kids praised for “trying hard” did better on tests and were more likely to take on difficult assignments than those praised for being “smart”.

“Praising attributes (品质) or abilities makes a false promise that success will come to you because you have that quality, and it devalues effort, so children are afraid to take on challenges,” says Dweck, now at Stanford University. “They figure they’d better quit while they’re ahead.”

1.The underlined words “Praise-aholic kids” refer to kids who are ______.

A. tired of being praised

B. extremely fond of being praised

C. very proud of being praised

D. worthy of being praised

2.The author quoted Dr. Dweck’s words in the last paragraph in order to make the article ________.

A. more persuasive　　　　　　　　　　 B. better-organized

C. better-known　　　　　　　　　　　　 D. more interesting

3.We can infer from the passage that _____.

A. praise for results works better than praise for efforts

B. praise for efforts should be more encouraged

C. praising a child’s achievements benefits his or her success in life

D. praising a child’s abilities encourages him or her to take on challenges

For 40 years, people in London have been happy to see parakeets (马尾鹦鹉) in their parks. The shocking green body and long tail have brought a bright color to the parks, which have attracted a lot of people.

However, the parakeets are no longer welcome. They will push out local birds from trees to build their own nests, and will also take most of the food in the parks, such as seeds, fruit and nuts.

Sometimes by accident, plants and animals are carried to new places. They are transported by trains, ships or even planes. Often, animals like fishes get transported in the water containers of ships.

People have been painting pictures for at least 30,000 years. The earliest pictures were painted by people who hunted animals. They used to paint pictures of the animals they wanted to catch and kill. Pictures of this kind have been found on the walls of caves in France and Spain. No one knows why they were painted there. Perhaps the painter thought that their pictures would help them to catch these animals. Or perhaps human beings have always wanted to tell stories in pictures.

About 5,000 years ago, the Egyptians and other people in the Near East began to use pictures as a kind of writing. They drew simple pictures or signs to represent things and ideas, and also to represent the sounds of their language. The signs these people used became a kind of alphabet(字母表).

The Egyptians used to record information and to tell stories by putting picture-writing and pictures together. When an important person died, scenes and stories from his life were painted and carved on the walls of the place where he was buried. Some of these pictures are like modern comic-strip (连环漫画) stories. It has been said that Egypt is the home of the comic strip. But, for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple. The ordinary people could not understand it.

By the year 1,000 BC, people who lived in the area around the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write, and there were fewer of them than in the Egyptian system. This was because each sign, or letter, represented only one sound in their language. The Greeks developed this system and formed the letter of the Greek alphabet. The Romans copied the idea, and Roman alphabet is now used all over the world.

These days, we can write down a story, or record information, without using pictures. But we still need pictures of all kinds: drawings, photographs, signs and diagrams. We find them everywhere: in books and newspapers, in the street, and on the walls of the places where we live and work. Pictures help us to understand and remember things more easily, and they can make a story much more interesting.

1.Ancient people in France and Spain painted pictures on walls of caves probably because ______.

A. they loved animals

B. they enjoyed seeing pictures

C. they preferred painting pictures to telling stories

D. they thought pictures helpful

2.The Greek alphabet was simpler than the Egyptian system for all the following reasons EXCEPT that　　 ______.

A. the former was easy to write

B. there were fewer signs in the former

C. the former was easy to pronounce

D. each sign stood for only one sound

3.In the last paragraph, the author thinks that pictures ______.

A. should be made easy to understand

C. should be made interesting

D. are disappearing from our life

4.The possible title of this article may be ______.

We human beings haven’t been good friends to animals. For thousands of years, we have been polluting the environment, making it hard for animals to live on the planet. We have been killing animals for their fur, feathers or meat, or simply because they are dangerous. As a result, many kinds of animals have disappeared forever. Hundreds more are on the endangered list today.

Should we care about animals? Of course we should. If animals of a certain kind all disappear, they will never come back again. Animals are more than just resources of things we need. Every kind of animal has its place in the balance of nature. Destroying any kind of animal can lead to many problems. For example, when farmers killed large numbers of hawks, the corn and grain that the farmers stored were destroyed by rats and mice. Why?  Because hawks eat rats and mice. With less and less hawks to keep down their numbers, rats and mice multiplied quickly. And if people kill too many birds, more and more insects will eat the crops.

Luckily, we’ve realized that we shouldn’t kill animals any more. And people are working hard to save those animals that would disappear soon. The government also passed laws to protect the endangered animals. In fact, quite a few countries have passed such laws. These laws forbid the killing of any kind of animal on the endangered list. We should try our best to protect and save the endangered animals.

1.The text calls on us to__________.

A．keep animals at home                    B．protect the environment

C．protect the endangered animals            D．know more about the balance of nature.

2.Why do people kill animals?

A．Animals cause many serious problems.

B．They kill animals for something they need.

C．Animals destroy their natural resources.

D．They kill animals to protect the environment

3.The example that farmers killed hawks shows that__________.

A．there were too many rats and mice

B．hawks are the most important in the nature

C．animals are good food resources

D．every kind of animal is important in nature
