Question: The common cold is the world's most widespread illness, which is plagues that flesh receives. The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes. During the First World War soldiers who spent long periods in the trenches , cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp , naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose. If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains--taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on. No one has yet found a cure for the cold. There are drugs and pain suppressors such as aspirin, but all they do is to relieve the symptoms . The passage mainly discusses _ . A) the fallacy about the common cold B) the experiments on the common cold C) the reason and the way people catch colds D) the continued spread of common colds
Answer: A

Question: Environmental protection was stressed at Kanas, a growing tourism destination in Northwest China's Xinjiang Uygur Autonomous Region, famous for its attractive scenery and its "lake monster". "All of the hotels and restaurants will _ from the scenic site to 30 kilometers away," said Jim Liquan, an official with the Kanas Environment and Tourism Bureau. The move aims to protect environment of Kanas, a scenic site that is part of the European ecosystem and bordersprefix = st1 /Kazakhstan,RussiaandMongolia. Meanwhile, construction of environmental facilities including sewage and rubbish treatment plants will be completed soon. According to Mao Ken, chief of AltayPrefecturewhere Kanas is located, the government invested 1 billion yuan (US $ 120 million) on environmental facilities. "Education for tourists is also important," he said. An education center is being created to provide information on how to protect the environment in Kanas. But he vowed that the government would not interfere with the lives of traditional residents in Kanas. It is expected that Kanas will receive more than 500,000 tourists this year, 4,000 more than last year, according to the official. "However, there are still few overseas visitors," he said. Statistics showed that only 2 percent of the total number of tourists is foreigners. "This is partly because the transportation facilities connecting Kanas are still not convenient enough," Mao said. At present, there is only one highway connecting Kanas. "Upon request from tourists, construction of an airport will start this month and will be completed by the end of next year," the official said. A railway line connecting Kuitun and Altay will also open to traffic in 2008 to make it possible to travel to Kanas by train, probably bringing in more tourists. We can learn from the passage that Kanas is _ . A) a lake B) a town in Europe C) a Kazakhstancity next to Xinjiang Uygur Autonomous Region D) a tourism destination located in AltayPrefecture

Question: There is an interesting, but at the same time a sad phenomenon now: there is a rise in the number of singers and bands that have little to do with good music.Many singers or bands know little about what good music means.What is the cause of this rise? Most of these singers have taken music as a "job" because it is a good source of making money.And if you have a good appearance and also expensive clothes to show off at your concerts or at different appearances in public, then your voice is not as important as it should be.The public will prefer to admire more the most interesting parts of your body, whether you are a girl or a boy.They will even forget about the fact that you are there to show your music skills, not your dancing, which is important too, but not at such a high level. Therefore, we can see many young girls on TV who look very good but who have nothing to do with music.They choose to wear very provocative clothes to catch attention, but when it comes to singing they are a complete mess and one doesn't need to have an ear for music to notice their lack of talent.But anyway, they have concerts and they enjoy travelling from one place to another.It is the public's fault because they accept this and are pleased with this commercial music.People who enjoy this kind of music are generally young people while adults prefer listening to old good bands. However, the young generation should understand while appearance is important, it is less important than talent and a good voice.If somebody has a great voice and wants to become a singer, he should take some special courses in this area, because they will help them improve singing abilities. What do you think is the author's attitude towards the rising number of new singers and bands? A) Critical. B) Supportive. C) Tolerant. D) Worried.
