June 26, 2000 — the Human Genome(基因组) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遗传的) map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延长) human life. But those communities and policy makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.
For the last few years, the genetic advances in the developing field of biotechnologyhave provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic codehave opened a world of possibilities for human health, as well as for the popular imagination.
While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.
Why did the scientists work hard at mapping the human genome?

A．Because the human genome can destroy many illnesses.

B．Because the human genome's completion can help them get rid of many diseases.

C．Because they wanted to be better known than others.

D．Because the human genome can provide a lot of chances of work.

Which country studied the genes most rapidly in the world?

A．Japan.

B．Germany.

C．The United States.

D．China.

Which of the following is NOT true?

A．If the genes can be found, scientists can study many new ways to cure illnesses.

B．The scientists have made great progress in connecting the genes with the cancers.

C．Many medical companies show great interest in drawing the human genome map.

D．The United States began the Genes Study early in the 19th century.

The author suggests that the Human Genome Project can cause _______.

A．the policy makers to feel very worried and careful

B．the scientists to work harder

C．many people to find work easily

D．a lot of companies to produce many new drugs

The main idea of this article is about _______.

We are so used to having a cup of tea before heading off to work, during work or after getting back from work. Tea breaks are more like a custom that takes place regularly several times a day. This tea break tradition has been happening during the past 200 years or so. Tea just happens to be a wonderful drink for most of us. The day simply feels incomplete without a hot cup of tea. However, is tea good for you?
In 2006, the papers were flooded with the news of research showing that drinking 2-3 cups of tea a day is as beneficial as drinking water, with even some additional health benefits. Another report published in November 2009, stated that drinking up to eight cups of tea a day is good for you. The research conducted by nutrition expert Dr. Carrie Ruxton, debunked (揭示…的真相)the popular stories about caffeinated(含咖啡因的)drinks like tea, coffee and cocoa. According to Dr. Ruxton, the caffeine present in tea tends to lower the risk of heart attacks and strokes. She says that drinking 8 cups of tea a day gives the drinkers “the best levels of health-giving substances” present in tea and other caffeinated drinks.
Contrary to popular belief that tea does not contain more caffeine than coffee, it actually contains almost half the amount. Caffeine is a natural thing found in many types of food and drink. It’s also something that can give you a much needed lift for a demanding and tiring afternoon ahead. Research shows that proper amounts of caffeine are safe for most people.
So why not take full advantage of your tea breaks at work, or make time for afternoon tea while out shopping at the weekend? And remember that tea is not just a great drink, but it helps to keep you looking and feeling healthy.
59. What is mainly talked about in the first paragraph?
A. The types of tea. B. The tea custom     C. How to drink tea    D. When to drink tea.
60. Reports in the newspapers show that ______.
A. drinking tea is a healthy habit                 B. new ways of drinking tea appear
C. drinking tea is harmful to health             D. people don’t like to drink tea any more
61. Caffeine in tea ____.
A. can make you energetic                       B. gives you a good rest
C. may cause heart attacks                       D. is more than that in coffee
62. What would be the best title for the passage?
A. Tea and disease                                   B. Tea—a healthy drink
C. Tea, coffee and cocoa                          D. Drink tea or coffee

B
It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
　As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
　Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the sky. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
　These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
　Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
　We know a lot about our world, but there are still many answers that we do not have, and we are curious.
55．According to the passage, which of the following statements is true?
　 A．People are curious in the same way.
　 B．People in different countries are interested in different things.
　 C．Men and women are curious about different things.
　 D．People of different ages are interested in different things
56．Scientists who work with the biological sciences study____.
A．the earth , the oceans and the sky B．man-made things
C．plants and animals D．ocean water
57．When you run, your muscles need ____.
A．more nutrition and oxygen B．more signals   C．more salt D．water
58．People are always curious because ____.
A．they cannot explain many things    B．they know nothing about the world
C．they know little about the world    D．they want to be scientists

第三部分阅读理解（共20小题；每小题2分，满分40分）
第一节阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
When I was a kid, I always used to wonder how in the world my father work outside in the winter without a coat. It could be minus 20 degrees centigrade and there’d be Dad, removing snow, or perhaps chopping some wood --- his coat thrown aside--- wearing a shirt , a cap, and a pair of gloves.
“Aren’t you cold, Dad?” I’d ask. “No,” Dad would reply. “I’m not cold--- working too hard to be cold.”
Many times I wondered whether my father was an extremely tough man, or whether he was foolish.
One time when I was quite young, perhaps five or so, I went ice fishing with Dad. It was a bright, clear day—and bitterly cold.
After we’d been out on the ice for a little while, my feet started getting cold.
“ Daddy, my feet are cold.” I said.
“Yeah, it’s cold out here today,” he replied.
“Tell you what,” he said. “Walk around. Make some circles in the snow. See how many different patterns you can make. That will get your feet warm.”
Now, I was just a little girl at the time but I remember thinking, “How in the world will walking around in the snow make my feet warm? Dad must be out of mind.
But he was my father, after all. I made circles in the snow. I made squares. Pretty soon I was having so much fun making patterns in the snow. I forgot about my feet being cold.
Now, all these years later, I know, too, from personal experience how my father was able to take his coat off and work outside in the winter wearing just a shirt, a cap and gloves. Because I do it, too. “Aren’t you cold?” my husband asked one winter day. “No,” I replied. “I’m not cold—working too hard to be cold.”
I hope my husband has decided I’m both tough and smart. But I guess quite a bit of the time he thinks I’m foolish.
Wherever Dad is in that great big farm in the sky—I’m sure he can’t help but smile whenever I take my coat off while I’m working outside in the winter.

If you were to come up with a list of organizations whose failures had done the most damage to the American economy in recent years, you would probably have to start with the Wall Street firms that brought us the financial crisis．From there, you might move on to the automakers in Detroit．
But I would suggest that the list should also include a less obvious nominee: public education．
At its top level, the American system of higher education may be the best in the world．Yet in terms of its core mission---turning teenagers into educated college graduates--- much of the system is failing．
The United States does a good job enrolling （招生） teenagers in college, but only half of the students who enroll end up with a bachelor’s degree．
So identifying the causes of the college dropout crisis in the world’s largest economy matters enormously, and a new book called “Crossing the Finish Line” tries to do precisely that．Its authors are economists William Bowen and Michael McPherson, and a doctoral candidate Matthew Chingos．The first problem they diagnose is something they call under-matching．It refers to students who choose not to attend the best college they can get into．They instead go to a less selective one, perhaps one that is closer to home or less expensive．About half of the low-income students with a grade-point average of at least 3．5 in high school and an SAT score of at least 1,200 do not attend the best college they could have．“I was really astonished by the degree to which well-qualified students from poor families under-matched,” said Mr．Bowen．
In fact, well-off students attend the colleges that do the best job of producing graduates．Meanwhile, lower-income students -–even when they are better qualified—often go to colleges that excel（擅长）in producing drop-outs．“It’s really a waste,” Mr．Bowen said, “and a big problem for the country．” As the authors point out, the only way to lift the college graduation rate significantly is to lift it among poor and working-class students．Instead, it appears to have fallen．
What can be done? Money is clearly part of the answer．
63. Which of the following would people first think of as a factor responsible for the American financial crisis according to this passage?
A．The government．           B．Public education
C．The Detroit automakers．   D．The Wall Street firms．
64．What is a big problem with American higher education?
A．It is hard to enroll enough students into college．
B．Many colleges are experiencing low rate of graduation．
C．Many college students stay away from classes．
D．It is hard for many colleges to get financial aid from the government．
65．The title of the book Crossing the Finish Line probably means______．
A．running to the end of the line        B．going to college
C．finishing college education     D．working hard in college
66．Why do some students under--match ?
A．Because they have financial difficulty．       B．Because they face ambition crisis．
C．Because they lack confidence．         D．Because they can’t get guidance．
67．The passage is mainly about _______．
A．problems with secondary American education and possible solutions
B．America’s financial crisis, its cause and influence
C．low rate of American college graduation, its cause and its influence
D．relationship between American education and its economy
