It’s not a particular brain region that makes someone smart or not smart. Nor is it the strength and speed of the connections throughout the brain or such features as total brain volume. Instead, new research shows, it’s the connections between very specific areas of the brain that determine intelligence.
“General intelligence actually relies on a specific network inside the brain, and this is the connections between the gray matter, or cell bodies, and the white matter, or connecting fibers between neurons(神经元),”said Jan Glascher, lead author of a paper appearing in this week’s issue of the Proceedings of the National Academy of Sciences.
The results weren’t entirely unexpected, said Keith Young, vice chairman at Texas A﹠M Health Science Center College of Medicine in Temple, but “it proves that good communication between various parts of brain are very important for this general intelligence.”
“People noticed a long time ago that, in general, people who are good test-takers did well in a lot of different subjects,”explained Young. “If you’re good in mathematics, you’re also usually good in English. Researchers came up with this idea that this represented a kind of overall intelligence.”
Hoping to learn more, some experts located 241 patients who had some sort of their lesions (损害). They then diagrammed the location of their lesions and had them take IQ testes. “We took patients who had parts of their brain damaged, tested them on intelligence to see where they were good and where they were bad, then we connected those scores across all the patients with the location of the brain lesions,”Glascher explained. “That way, you can know the areas that are associated with reduced performance on these tests, which means these areas are really important for general intelligence.”
“These studies suggest results based on the absence of brain tissue (组织),”added Paul Sanberg, famous professor and director of the University of South Florida Center. “It allows them to systemize and find areas important to intellingence.”
1. Which of the following is the best title for the passage?
A. General Intelligence Depend on Brain Volume
B. Scientists Explain Mysteries of Intelligence
C. Science Research Done on Human Brain
D. Brain Lesions Cause Patients Stupid
2.According to Keith Young, we can infer that_____________.
A. the parts of brain are working smooth on their own
B. a person good at maths has obstacles learning languages
C. overall intelligence will make a person successful
D. Jan Glascher’s article really shocks the world
3. Why did experts locate 241 patients with some sort of brain lesions?
A. To diagram the location of their lesions.
B. To take IQ tests to the patients.
C. To know more about the secrets of intelligence.
D. To take better care of the patients.
4.From the diagram, the experts concluded that_____________.
A. the absence of brain tissue will influence intelligence
B. the brain lesions can improve the performance
C. patients with brain lesions will get a high score
D. Some areas totally determine the ability of intelligence

Not long ago , Richard Denniston found himself suffering the same pain that millions of other pet owners have faced . His little Scottish dog had a brain tumor(肿块)and would soon die. Like others who faced the problem before him , Denniston just wanted to end his pet’s suffering . However , he took one step further.
Deniston , an expert who studies animals , collected a tiny skin sample from the dog and took it to his laboratory at Louisiana State University. There he cultivated it and froze it in liquid nitrogen.
From that idea , Denniston started a new technology .Denniston’s company will save pet’s DNA $500,plus a monthly storage fee of Us $10, until cloning becomes a reality .
Thanks mostly to the contribution of a California multimillionaire , that day may not be so far off.
“It could happen extremely soon if everything went on well.”says Mark Westhusin , a professor leading a dog cloning team . Most experts put successful dog cloning a year to five years down the road . The cost is bound to be expensive at first , but it would eventually drop to a few thousand dollars.
Since Dolly , the sheep which was first cloned in 1997 ,cattle ,goats ,mice and monkeys have been cloned in labs . Pets are likely to be next.
“I really believe that the technology is going to become available for many species in the near future ,”Denniston says .
1. After his pet died ,Richard Denniston_______.
A. did something more than the ordinary pet owners
B. did as other pet owners
C. did nothing but feel very sad
D.could not help feeling lonely without his dear pet
2. Richard Denniston_________in liquid nitrogen for an experiment.
A. was a doctor who put his dog
B. was an animal expert who put a piece of his dog’s skin
C.was an expert at collecting skin samples who then put them
D.took great interest in freezing

3. The underlined word “cultivated ”in Para . 2 probably means_________.
A. bought B.discovered C.caught D.trained
4. Cloning will cost people_______.
A. a lot of money in five years .
B. much in the beginni

D.much at first and then might be reduced to a few thousand dollars.
Thousands of people living in the Chinese eapital will celebrate the start of the Chinese New Year by heading for the ski resorts(滑雪场).Never mind that Beijing’s dry weather seldom produces
Now. It is cold enough in winter for snow-making machines to make a covering for the hills north to
The capital. And the rapid growth of a pleasure-seeking middle class has formed the basis for this
New craze(热潮).
Since Beijing’s first ski resort was opened ten years ago, the sport has enjoyed an astonishing increase.There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr.Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that could soon lead Chinese to head for the ski resorts of Europe. In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can’t really match the equipment and services of some ski resorts
In Europe.
Beijing’s sking craze is partly a result of the recent increase in private(私有的)cars. This has led to the growth of a leisure industry in the capital’s suburbs(郊区).which until the late-1990s were unreachable to ordinary people. According to Mr. Wei,About 40% of the visitors to his resort some in their own cars. The rest are bused in by schools, businesses or government offices.
The problem is making money.Starting ski resorturequires quite a lot of money:hiring land from the local government,preparing the hills,buying snow machines,making sure there are enough
water and electricity to run them,and buying ski equipment for hiring out to customers.The ski resort where Mr.Wei works cost nearly $4m to set up.And,as so often in China when someone comes up with a good idea,many others rush in and price wars break out.Beijing now offers some of
the cheapest ski training classes in the world,though with most people rather new to the sport, expecting a few more doing the same job.
50.What does this text mainly talk about?
A.Convenience for skiers brought about by private cars
B.Skiing as a new way of enjoying one’s spare time
C.Things to be considered when starting a ski resort
D.A sudden increase of ski training classes in Beijing
51.Why are some Chinese likely to go skiing in Burope?
A.To visit more ski areas
B.To ski on natrual snow
C.For a large collection of ski suits
D.For better services and equipment
52.The underlined words”leisure industry”in Paragraph 3 refer to
A.transport to ski resorts
B.production of familycars
C.business of providing spare time enjoyments
D.part-time work for people living in the suburbs
53.What is the main problem in running a ski resort?
A.Difficulty in hiring land
B.Lack of business experience
C.……ski resorts.
D.Shortage of water and electricity

阅读下面短文,根据第58至第60小题的具体要求,尽可能简要回答问题,并将答案转写到答题卡上。
If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.

For 52 years my father got up at 5:30 am every morning, went to work, and returned home at 5:30 pm. I never saw my father stayed home from work ill, nor did I ever see my father lay down to take a nap. He had no hobbies, other than taking care of his family. All he asked from me, his daughter, was to help him while he was repairing something, so we could have some time to talk.
For 22 years, after I left home for college, my father called me at 9:00 am every Sunday. Nine years ago when I bought my first house, my father, 67 years old, spent eight hours a day for three days in the 80-degree Kansas heat, painting my house. He would not allow me to pay someone to have it done. All he asked for was a glass of iced tea. Five years ago, at age 71, my father spent five hours putting together a swing set for my daughter. Four years ago, my father drove all the way from Denver to Topeka, with an eight-foot Colorado Blue Spruce (云杉) in his truck, so that we could have a part of Colorado growing on our land.
On the morning of January 16, 1996, my sister telephoned me; my father was in the hospital with an aneurysm(动脉瘤) in Florida. I got on an airplane immediately, and on the way I realized that I hadn’t communicated with him as much as I’d always wanted to. I vowed(发誓) that when I arrived, I would have a long talk with him. I arrived in Florida at 1 am, only to find that my father, at the age of 76, had passed away at 9:12 pm. This time it was he who did not have time to talk, or time to wait for me.
