考题 Passage TwoQuestions 26 to 30 are based on the following passage.①The threat of a global outbreak (疾病大爆发) of bird flu makes it urgent for the international community to cooperate effectively. Wealthy countries will have to provide hundreds of millions of dollars for the testing and production of medicines necessary for treating patients suffering from bird flu. Developing countries, particularly in Southeast Asia, where the bird flu virus (病毒) has spread since 1997, must work out special programs so that farmers will not hide signs of possible outbreaks. In addition, the way such farm birds as chickens and ducks are traditionally raised and marketed in the developing world should be changed; there should be more distance between the birds and their keepers. Countries should deal with the disease with joint effort. If one country is inadequately prepared, it will be a threat to every other country.②The potential effects of a national outbreak of bird flu are enormous. Firstly, an outbreak may kill large numbers of people. World Health Organization (WHO) estimates that an outbreak similar to the mild Hong Kong flu of 1968 could kill as many as 7.4 millions people. If it were as dangerous as the 1918 Spanish flu, which killed 50 million, the number would be much higher. Secondly, such an outbreak may cause great financial damage. The latest outbreak of bird flu, which began in December 2003, has cost Southeast Asia more than $10 billion and depressed its GDP(gross domestic product) by 1.5 percent. If a new outbreak of bird flu were to last for a whole year, $800 billion would be lost.③Despite the 124 human cases and 63 deaths from bird flu since December 2003, the virus remains mainly a disease of animals. However, the more animals that die of the disease, the more chances it has of spreading to people. Large numbers of dead or dying birds mean that more people will be exposed to the virus and change into a virus with new characteristics. If the international community works together efficiently, man can surely prevent such a virus and possibly save millions of lives.26. Faced with the threat of a global outbreak of bird flu, the international community should ________.A. establish new marketsB. work together effectivelyC. stop birds from flying to other countriesD. raise fewer chickens and ducks

考题 共用题干 第一篇New Attempts to Eradicate AIDS VirusA high-profile attempt to eradicate the AIDS virus in a few patients continues to show promise.But researchers won't know for a year or more whether it will work,scientist David Ho told journalists here Wednesday for the Fourth Conference on Viruses and Infections."This is a study that's in progress,"says Ho,head of the Aaron Diamond AIDS Research Center, New York.The study involves 20 people who started combinations of anti-HIV drugs very early in the course of the disease,within 90 days of their infections.They'ye been treated for up to 18 months.Four others have dropped out because of side effects or problems complying with the exacting drug system.The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining patients.And,in the latest development,scientists have now tested lymph nodes and semen from a few patients and found no virus reproducing there,Ho says."Bear in mind that undetectable does not equal absent,"Ho says.Ho has calculated that the drugs should be able to wipe out remaining viruses一at least from known reservoirs throughout the body—in two to three years.But the only way to prove eradication would be to stop the drugs and see if the virus comes back.On Wednesday,Ho said he wouldn't ask any patient to consider that step before 2(1/2)years of treatment.And he emphasized that he is not urging widespread adoption of such early,aggressive treatment outside of trials.No one knows the long-term risks.But other scientists are looking at similar experiments.A federally funded study will put 300 patients on triple-drug treatments and then see if some responding well after six months can continue to suppress the virus on just one or two drugs,says researcher Douglas Richman of the University of California,San Diego. Some patients in that study also may be offered the chance to stop therapy after 1 8 months or more,he says. We prove that the drugs have wiped out the remaining viruses by________.A:using up all the drugs at onceB:waiting for the virus to die slowlyC:asking the patients'feeling about the diseaseD:stopping the drugs to see if the virus comes back

考题 问答题Directions:In this section, there is one passage followed by 5 questions. Read the passage carefully, then answer the questions in as few words as possible (not more than 10 words). Remember to write the answers on the Answer Sheet.  Questions 1-5 are based on the following passage.  Many people today are worried about bird flu. They are afraid that it will pass from birds to humans and that thousands of people will die in a pandemic. In 1918 a flu virus killed about 50 million people around the world. The virus was called Spanish influenza (or Spanish flu, for short) because Spanish newspapers first described the disease. Now, after nine years of work, scientists in an American laboratory in Atlanta, Georgia, have produced a copy of the Spanish flu virus. They are also going to publish the genetic sequence of the virus on the Internet and some experts are afraid that other laboratories could copy the virus.  Scientists have copied the virus because they want to understand why the 1918 Spanish flu pandemic killed so many people. In a report in the journal Science, Dr. Jeffery Taubenberger and a team of scientists in the USA show that the copied virus is extremely powerful. The scientists injected the virus into mice and the mice began to lose weight very quickly. They lost 13% of their weight in two days and all of the mice died within six days.  “I didn’t expect it to be as lethal as it was,”Dr. Terrence Tumpey, one of the scientists in the team, told the journal Nature. In another experiment, they injected more mice with a normal type of flu. The mice lost weight at first but then they got better and did not die. The experiments showed that the mice with the Spanish flu virus had 39,000 times more flu virus in their bodies than the second group of mice.  The scientists who copied the virus say their work has already provided important information about the virus and helps to explain why it is so lethal. But other experts are worried that the virus could escape from the laboratory. “Some people will think that they have really created a biological weapon,” said Professor Ronald Atlas of the University of Louisville in Kentucky. “I am even more worried now than I was before about the possibility of a flu pandemic. The 1918 flu pandemic started with bird flu and that might happen again today with Asian bird flu.”  Some scientists are worried about the publication of the genetic sequence on the Internet. They are afraid that biologists could copy the virus using the information on the Internet. This could be very dangerous.  It took a long time to copy the virus. Scientists used material taken from the lungs of people who died from the flu virus in 1918. In a second report in Nature, Taubenberger and his colleagues analyzed the genetic make-up of the virus. They were surprised to find that it was completely different from all the normal human flu viruses. This probably means that Spanish flu jumped from birds to humans and did not mix with a human virus first. This is very worrying for scientists because in the past everyone believed that a pandemic was only possible if a bird flu virus mixed with a human flu virus.  Taubenberger says it is very important to know what changes in the virus caused the 1918 Spanish flu virus. This will help scientists to work out which viruses might cause a pandemic. The H5N1 bird flu in Asia is already changing and it could infect humans, he said.  Viruses have escaped from high-security labs before. The SARS virus escaped at least twice, once in Taiwan and once in Singapore. But some scientists believe a pandemic will not happen even if the virus escapes, because most people are naturally immune and there are now a lot of drugs which protect people from flu.  Questions:  1.When was the Spanish flu pandemic?  2.How many people died in the Spanish flu pandemic?  3.Where did the scientists produce a copy of the Spanish flu virus?  4.How quickly did the laboratory mice die?  5.What is H5N1?

考题 单选题Questions 11 to 15 are based on the following passage. Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症),a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one. If children have flu-like symptoms, their parents ()A are advised not to give them aspirinB should watch out for signs of Reye syndromeC are encouraged to take them to hospital for vaccinationD should prevent them from mixing with people running a fever
