阅读理解。     Have you ever wished you could not feel pain? There are people in the world with this ability. They
do not know when they are hurting. Last year,Nature magazine published a report about six children who
have never suffered pain.The research team found the children after hearing about a boy who apparently
felt no pain. The boy stood on burning coals and stabbed his arms with knives to earn money.  He died in
a fall before the researchers could meet him.  But the team was able to find members of the boy"s extended family.  They also seemed unable to feel pain.
     This may lead to bad results. These children sometimes burned themselves with hot liquids or steam.
They sat on hot hearting devices.  They cut their lips with their teeth,but felt no pain.  Two of the children
bit off one-third of their
tongue. Yet they could feel pressure and tell differences between hot and cold.
     Why were they unable to feel pain? Doctor Woods and his research team studied
DNA-deoxyribonucleic acid from the children. They also examined DNA from the children"s parents. The team found that all had health. The researchers found that each child received a faulty version of the gene
from a parent.  The gene is called SCN9A.  It gives orders to a protein that serves as a passageway for
the chemical sodium(钠). All nerve cells have such passages.  This is how spinal cord and brain work.
     Researchers discovered something important about SCN9A. They linked it to a rare condition in
which patients suffer painful burning in their feet or hands.  The problems of these patients were nearly
opposite to those of the children who felt no pain.  "In patients with the painful burning hands and feet,
SCN9A was too active. The findings may mean better medical help for pain," Doctor Woods says.1. According to Doctor Woods,what do we know about the SCN9A in persons with no pain? A. There is no SCN9A.
B. There is little SCN9A.
C. SCN9A was not active.
D. SCN9A was active2. What is the purpose of Doctor Woods and his research team studying DNA from the children?A. To find out why children don"t feel pain.
B. To prove their supposition.
C. To obtain some faulty gene.
D. To locate the nerve cells.3.  What is the main idea of the second paragraph?  A. Some bad results of the patients.
B. The cause of the disease.
C. The cure of the disease.
D. The differences between hot and cold.

The American humorist,Will Rogers,used to say," All I know is what I read in the newspapers". This was an exaggeration for humorous purposes,but it is true that newspapers are an important source of information. Many people begin their day by reading the paper. In this way they leam what is going on in the world. Sometimes,however,they don"t have time to read the news carefully and must be satisfied with a quick look at the front page;at other times they may be in such a hurry that they have time only to glance at the headlines. There are newspapers to satisfy every reader. In the big cities there are many types of papers,with several different editions every day. In small towns there are fewer newspapers and perhaps only one edition each day. In some areas the paper is printed weekly. Most newspapers have several sections,especially on Sundays when the edition is larger than usual. There are,in addition to the front page with the most important news,the sports section,the society page, the comics,the amusement section,a business page,and the editorials. Another type of publication which helps keep the population informed is the magazine. Some magazines are published weekly,others are put out monthly. There are news magazines,literary magazines, and magazines for such special interests as photography,sports,art,and music. Some are primarily for men,others for women,and there is a selection of children"s magazines,too. In the United States,there are publications for every taste and interest.

108 cities in China took part in the World Car Free Day on Saturday to promote environmentally friendly transport and ease increasingly grid-locked city streets. It"s a highlight of a nationwide urban public transport week. People were urged to take public transport,ride bikes or walk. To help out,more than 200 new buses took to the streets. And the Beijing Subway laid on 10 more trains for rush hour. A Beijing resident said,"Today is car free day,and I do find the traffic much better and the bus can go much faster. " Another resident said,"I spent only half an hour going to work. It took me twice as long before,and I can find seat on the bus today. " But in some areas not signed up for traffic control,endless lines of cars can still be seen. Some people say they just can"t do without their cars. Another Beijing resident said,"Some people are willing to give up driving,but on certain days when I have to take my child to school or weekend classes,the public transport is so bad that I can"t do it without a car. " But the concept of "green"traffic is catching on. People say they believe it"s the first and honest step in facing the serious traffic and environmental problems. A driver said,"The car free day has a very important symbolic meaning. It does not mean that we must give up cars. It is to promote a concept,to encourage more people to contribute to the protection of the environment. " The Ministry of Construction calculates"Car Free Day"will cut 3,000 tons of emissions and save 33 million liters of gasoline.

People often talk as if shyness is a disease or mental condition that can be cured. I prefer to think of it as an emotional disability. It"s something we are bom with and something we carry with us in our entire lives. There are too many people,however,who seem to be determined to find some ways of doing away with their shyness. In my opinion,it"s a waste of time. I don"t mean that we should do nothing about it;quite the contrary,I think we need to separate the basic fact of shyness from our ability to take part in a social environment. Look at one of the most famous shy people of them all,Johnny Carson. This man is painfully shy,yet for decades he made a living talking and associating(交往) with different people every night,in front of a national audience. Carson has never done away with his shyness,but he has successfully found a way to deal with it to the extent that he could be, not just a talk show host,but a legend(传奇) among talk show hosts. Look also at Sally Fields,who has recently admitted her problem with shyness. This is a woman who has appeared in many films,TV shows and interviews,yet in her early years she was so shy that she tumed down a lunch invitation from Jane Fonda because she was terribly afraid of meeting her. I guess that our shyness is there because each of us is bom with some msecurity(不安全感) and this insecurity prevents us from reaching out to others the way people with a more open personality do. As we grow up and become adults,we allow our social skills to grow and develop. But we are still stuck in kindergarten or elementary school or wherever it was when our shyness took root in our soul.
1. In the author"s view,shyness can be explained as ______.
A. a disease that can be easily cured B. a not very normal mental condition C. an emotional disability D. something we pick up after birth
2. The author believes it"s a waste of time to _____.
A. develop a healthy personality B. talk with as many people as possible C. study where shyness comes from D. look for ways to do away with one"s shyness
3. Which of the following is TRUE of Johnny Carson?
A. He dared to speak in front of a national audience. B. He did away with his shyness carefully. C. He was described as a hero in some legend books. D. He failed to become a good talk show host.
4. The passage tells us that Sally Fields was ______
A. proud all the time B. impolite when young C. shy in her early years D. close to Jane Fonda
5. The author thinks that our shyness is there because ______.
A. we are not open enough B. we don"t feel safe at heart C. we try to reach out to others all the time D. we lack certain social skills
