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. According to the author, knowing the cause of the misery will help（）A、shorten the duration of the illnessB、the patient buy medicine over the counterC、the patient obtain cheaper prescription drugsD、prevent people from catching colds and the flu

考题共用题干 Tiny InvadersThe human body is truly amazing.It allows us to sense the world around us,to do work and have fun,and to move from place to place.In fact,the human body does its work so well that most people don't think about it very much一until they get sick.The germs（致病菌）that make people sick are everywhere.You can't see them, but they're there.They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you are breathing.There are two types of germs:viruses and bacteria（细菌）.Viruses are germs that can only live inside animals or plants.Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so good.They can make you sick.Bacteria can cause sore throats（喉痛）and ear infections.How can you stop these tiny invaders from making you sick?Your skin is the first de-fense against germs.You can prevent some illnesses simply by washing,with soap and wa-ter.But germs can still enter the body through small cuts in the skin or through the mouth, eyes,and nose.Once germs are inside your body, your immune（免疫的）system tries to protect you.It looks for and destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.That way you will not get the same illness twice.You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune system strong.You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your antibodies attack it.All bacteria cause illnesses.A:RightB:WrongC:Not mentioned

考题 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

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?
