"I left Tangier, my birthplace, the 13th of June 1325 with the intention of making the pilgrimage（朝圣） to Mecca．．． to leave all my friends both female and male, to abandon my home as birds abandon their nests．" So begins an old manuscript（手稿） in a library in Paris－the travel journal of Ibn Battuta．

Almost two centuries before Columbus, Ibn Battuta set off for Mecca, returning home three decades later as one of history's great travelers． Driven by curiosity, he journeyed to remote comers of the Islamic world, traveling through 44 modern countries, three times as far as Marco Polo． Little celebrated in the West, his name is well known among Arabs． In his hometown of Tangier, a square, a hotel, a cafe, a ferry boat, and even a hamburger are named after him．

Ibn Battuta stayed in Mecca as a student for several years, but the urge to travel soon took over． In one adventure, he traveled to India seeking profitable employment with the sultan of Delhi．On the way, he described his group being attacked in the open country by 80 men on foot, and two horsemen． "We fought… killing one of their horsemen and about twelve of the foot soldiers… I was hit by an arrow and my horse by another, but God in his grace preserved me… "． In Delhi, the sultan gave him the position of judge, based on his prior study at Mecca． But the sultan had an unpredictable character, and Ibn Battuta looked for an opportunity to leave． When the sultan offered to finance a trip to China, he agreed． IbnBattuta set off in three ships, but misfortune struck while he was still on the shore． A sudden storm grounded and broke up two ships, scattering treasure and drowning many people and horses． As he watched, the third ship with all his belongings and slaves （one carrying his child）, was carried out to sea and never heard from again．

After a lifetime of incredible adventures, Ibn Battuta was finally ordered by the sultan of Morocco to return home to share his wisdom with the world． Fortunately, he agreed and wrote a book that has been translated into numerous languages, allowing people everywhere to read about his unparalleled journeys．

Every fall, like clockwork, Linda Krentz of Beaverton, Oregon, felt her brain go on strike. “I just couldn’t get going in the morning,” she says. “I’d get depressed and gain 10 pounds every winter and lose them again in the spring.” Then she read about seasonal affective disorder, a form of depression that occurs in fall and winter, and she saw the light-literally. Every morning now she turns on a specially constructed light box for half an hour and sits in front of it to trick her brain into thinking it’s still enjoying those long summer days. It seems to work.

Krentz is not alone. Scientists estimate that 10 million Americans suffer from seasonal depression and 25 million more develop milder versions. But there’s never been definitive proof that treatment with very bright lights makes a difference. After all, it’s hard to do a double-blind test when the subjects can see for themselves whether or not the light is on. That’s why nobody has ever separated the real effects of light therapy from placebo(安慰剂) effects.

Until now. In three separate studies published last month, researchers report not only that light therapy works better than a placebo but that treatment is usually more effective in the early morning than in the evening. In two of the groups, the placebo problem was resolved by telling patients they were comparing light boxes to a new anti-depressant device that emits negatively charged ions. The third used the timing of light therapy as the control.

Why does light therapy work? No one really knows. “Our research suggests it has something to do with shifting the body’s internal clock,” says psychiatrist Dr. Lewey. The body is programmed to start the day with sunrise, he explains, and this gets later as the days get shorter. But why such subtle shifts make some people depressed and not others is a mystery.

That hasn’t stopped thousands of winter depressives from trying to heal themselves. Light boxes for that purpose are available without a doctor’s prescription. That bothers psychologist Michael Terman of Columbia University. He is worried that the boxes may be tried by patients who suffer from mental illness that can’t be treated with light. Terman has developed a questionnaire to help determine whether expert care is needed.

In any event, you should choose a respectable manufacturer. Whatever product you use should emit only visible light, because ultraviolet light damages the eyes. If you are photosensitive, you may develop a rash. Otherwise, the main drawback is having to sit in front of the light for 30 to 60 minutes in the morning. That’s an inconvenience many winter depressives can live with.

1.What is the probable cause of Krentz’s problem?

A. An unexpected gain in body weight.

B. Unexplained impairment of her nervous system.

C. Weakening of her eyesight with the setting in of winter.

D. Poor adjustment of her body clock to seasonal changes.

2.By saying that Linda Krentz saw the light” (Line 4, Para. 1), the author means that she _______.

A. learned how to lose weight

B. realized what her problem was

C. came to see the importance of light

D. felt sleepy and blue

3.What is the CURRENT view concerning the treatment of seasonal depression with bright lights?

A. Its effect remains to be seen.

B. It serves as a kind of placebo.

C. It proves to be an effective therapy.

D. It hardly produces any effects.

4.What is psychologist Michael Terman’s major concern?

A. Winter depressives will be addicted to using light boxes.

B. No mental patients would bother to consult psychiatrists.

C. Inferior light boxes will emit harmful ultraviolet lights.

D. Light therapy could be beyond the tolerance of certain mental patients.

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

Because no light can get out, people can’t see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones.

Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “staff”, in an object.

Another kind of black hole is called “stellar”(星球黑洞). Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way.

The largest black holes are called “supermassive”(超大质量黑洞). These black holes have masses that are more than one million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths.

Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.

A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole.

When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.

1.The gravity of a black hole may become so strong that light cannot get out when ____________.

A. the star is going to die

B. special tools are used on it

C. other stars come close to it

D. it is seen from the space telescopes

2.According to the passage, which of the following is NOT true?

A. A black hole can be very tiny but extremely heavy.

B. The gravity of a black hole holds all light in its center.

C. Scientists observe high-energy light through their own eyes.

D. Some small black holes came into being as early as the universe.

3.Which can be inferred from the passage?

A. Every galaxy must have a black hole.

B. A galaxy is the center of the universe.

C. A galaxy consists of a large group of stars and planets.

D. Earth’s galaxy is called the Milky Way.

4.What does the last sentence in Paragraph 5 suggest?

A. Neither the sun nor the earth is as heavy as a black hole.

B. There is only one supermassive black hole at the center of the Milky Way.

C. The supermassive black hole had existed before the Milky Way was formed.

D. There is a reason why the large black holes are called “supermassive”.

5.The last two paragraph mainly focus on the question of _________.

A. what a black hole is

B. how black holes form

C. how big black holes are

D. how scientists know about black holes
