The splendid aurora light displays that appear in Earth’s atmosphere around the north and south magnetic(磁的) poles were once mysterious phenomena. Now, scientists have data from satellites and ground-based observations from which we know that the aurora brilliance is a massive electrical discharge similar to that occurring in a neon sign.

To understand the cause of auroras, first picture the Earth enclosed by its magnetosphere(磁層), a huge region created by the Earth’s magnetic field. Outside the magnetosphere, rushing toward the earth is the solar wind, a speedily moving body of ionized(離子化的) gases with its own magnetic field. Charged particles(粒子) in this solar wind speed earthward along the solar wind’s magnetic lines of force. The Earth’s magnetosphere is a barrier to the solar winds, and forces the charged particles of the solar wind to flow around the magnetosphere itself. But in the polar regions, the magnetic lines of force of the Earth and of the solar wind gather together. Here many of the solar wind’s charged particles break through the magnetosphere and enter Earth’s magnetic field. They then rush back and forth between the Earth’s magnetic poles very rapidly and ionize and excite the atoms of the upper atmosphere of the Earth, causing them to produce aurora radiations of visible light.

The colors of an aurora depend on the atoms producing them. The leading greenish-white light comes from low energy excitation of oxygen atoms. During huge magnetic storms oxygen atoms also undergo high energy excitation and produce pink light. Excited nitrogen(氮) atoms contribute bands of color varying from blue to violet. Viewed from outer space, auroras can be seen as dimly shining belts wrapped around each of the Earth’s magnetic poles. Each aurora hangs like a curtain of light stretching over the polar regions and into the higher latitudes. When the solar flares(閃光) that result in magnetic storms and aurora activity are very strong, aurora displays may extend as far as the southern regions of the United States.

1.What is it that directly gives off aurora light?

A. The Earth’s magnetic field.

B. The solar wind’s magnetic field.

C. The Earth’s ionized particles.

D. The solar wind’s charged particles.

2.What does the third paragraph mainly discuss?

A. The appearance of auroras around the Earth’s poles.

B. The periodic change in the display of auroras.

C. The factors that cause the variety of colors in auroras.

D. The covering area of auroras based on their colors.

3.What can we infer from the passage?

A. The magnetosphere increases the speed of particles from the solar wind.

B. The color of greenish-white appears least frequently in an aurora display.

C. Earth’s magnetic field contributes to the variety and difference of aurora’s colors.

D. The strength of the solar flares has a positive effect on the extending distance of aurora.

Money is the root of all evil (邪惡) and new study claims there may be some truth behind the saying. Scientists at the University of California Berkeley, US, announced on February 27 that rich people are more likely to do immoral things, such as lie or cheat, than poorer people. The scientists did a series of eight experiments. They published their findings online in the Proceedings of the National Academy of Sciences (PNA《美國國家科學(xué)院院刊》).

They carried out the first two experiments from the sidewalk near Berkeley. They noted that drivers of newer and more expensive cars were more likely to cut off other cars and pedestrians at crosswalks. Nearly 45 percent of people driving expensive cars ignored a pedestrian compared with only 30 percent of people driving more modest cars.

In another experiment, a group of college students was asked if they would do immoral things in various everyday situations. Examples included taking printer paper from work and not telling a salesperson when he or she gave back more change. Students from higher-class families were more likely to act dishonestly.

According to the scientists, rich people often think money can get them out of trouble. This makes them less afraid to take risks. It also means they care less about other people's feelings.

Finally, it just makes them greedier. "Higher wealth status seems to make you want even more, and that increased want leads you to bend the rules or break the rules to serve your self-interest," said Paul Piff, lead scientist of the study.

Piff pointed out that the findings don't mean that all rich people are untrustworthy or all poor people honest. He said the experiments were to show how people living in different social situations express their instincts (本能) and values in different ways.

1.By saying "money is the root of all evil", the author wants to ________.

A. link wealth with bad behavior

B. draw readers' attention to the research

C. show how the saying proves the findings

D. defend rich people who do immoral things

2.According to the scientists, which is NOT the factor that makes rich people immoral?

A. They welcome risks.

B. They have more desires.

C. They believe money talks.

D. They become more selfish.

3.Why did the scientists do the experiments?

A. To show how social status affects people's morality.

B. To show people's instincts and values in different ways.

C. To test whether the saying "money is the root of all evil" is true.

D. To show the difference between higher-class people and lower-class people.

4.What does the passage really want to show us?

A. The poor are respectable.

B. Money is the root of all evil.

C. All rich people are untrustworthy.

D. The rich are more likely to act badly.

Tyler was born infected with HIV and his mother was also infected. From the very beginning of his life, he was dependent on medications (藥物) to enable him to survive. When he was five, he had a tube surgically(外科手術(shù)上) inserted in a vein(靜脈) in his chest. This tube was connected to a pump, which he carried in a small backpack on his back. Medications were connected to this pump and were continuously supplied through this tube to his bloodstream. At times, he also needed supplemented oxygen to support his breathing.

Tyler wasn't willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard, wearing his backpack and dragging his tank of oxygen behind him in his little wagon(小推車). All of us who knew Tyler were amazed at his pure joy in being alive and the energy it gave him. Tyler's mom often made jokes on him by telling him that he moved so fast she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard, she could quickly spot him.

This terrible disease eventually wore him down. He grew quite ill and, unfortunately, so did his HIV-infected mother. When it became clear that he wasn't going to survive, Tyler's mom talked to him about death. She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven.

A few days before his death, Tyler beckoned(召喚) me over to his hospital bed and whispered, "I might die soon. I'm not scared. When I die, please dress me in red. Mom promised she's coming to heaven, too. I'll be playing when she gets there, and I want to make sure she can find me."

1.Why did Tyler wear a backpack on his back when he was young?

A. Because his mother gave it to him as a gift.

B. Because he had no right to choose but to wear it.

C. Because he wanted to be different from the other kids.

D. Because there was a pump in it, which could help with his disease.

2.Tyler asked the writer to dress him in red when he died in order to ________.

A. show red is his favorite color.

B. see the writer again in the hospital.

C. make his mother recognize him easily.

D. persuade his mother to keep her promise.

3.What’s Tyler’s attitude towards death?

A. Excited. B. Fearful. C. Doubtful. D. Optimistic.

4.What does the writer want to tell us by writing this passage?

A. Even a child can teach us a lot.

B. Patients should be treated with respect.

C. People should have great courage to face the problems.

D. We should try our best to help those who are infected with HIV.

A little boy felt sorry for a butterfly struggling to from its chrysalis. He decided to the butterfly. So he peeled the chrysalis open for the butterfly. The little boy was so to watch the butterfly spread its wings and fly off into the sky. Then he was horrified he watched the butterfly fall to the ground and die because it did not have the muscle to keep flying. In fact, the butterfly’s struggle to the chrysalis helps the butterfly become stronger.

Like the little boy, too often want to protect their children from struggle in the of love. They don’t realize that their children need to struggle, to experience , to deal with disappointment, and to solve their own problems. Only in this way can children their emotional strength, become and develop the skills necessary for the even bigger struggles they will meet throughout their lives. Children experiencing sufferings can the ups and downs of life.

However, it isn’t helpful either in this case when parents lectures(訓(xùn)斥), blame and shame to what the child is experiencing. Mothers to say, “Stop crying and acting like a spoiled boy. You can’t always get what you want.” These words should be avoided.

Instead, parents can offer loving support. You can say, “Don’t lose . Be brave! You will succeed if you try again.” Then comes the tough part—no a no lectures. Simply allow him to discover that he can get over his disappointment and what he can do to get what he wants in the future.
