B
Many people catch a cold in the springtime or fall. It makes us wonder. If scientists can send a man to the moon, why can’t they find a way to deal with the common cold? The answer is easy. There are actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn’t a cure for each one.
When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and brings congestion（擁塞）in it. That is to say, you cannot breathe well. As a result, you feel terrible. However, your body is actually “eating” the virus. Your temperature rises and you get a fever, but the heat of your body is also killing the virus. Besides, you have a runny nose to stop the virus from getting into you. You may feel terrible, but in fact your wonderful body is doing everything it can to kill the cold.
Different people have different ways to deal with common colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people take hot baths; some drink warm water, milk, or things like that; other people take medicine to stop the fever, congestion, and runny nose.
Some scientists suggest you should not take medicine when having a common cold, saying that it is bad for you to do that. If you take medicine, your body will stop reacting to the virus and thus won’t have a way to fight it and kill it, which makes the virus stay in you longer. Bodies can do an amazing job on their own.

A. Why we never know which cold we will get.
B. Why scientists are able to send a man to the moon.
C. Why scientists cannot find a cure for the common cold.

57. Which of the following is NOT mentioned in the passage when we are suffering from colds?
A. Fever.       B. Headache.      C. Runny nose.       D. Congestion.
58. When you have congestion in your nose, ________.
A. you will not be able to breathe well
B. your temperature is going to rise
C. your blood is running too fast
D. you will have a runny nose
59. According to the passage, people may deal with common colds in different ways EXCEPT ________.
A. taking medicine   B. taking hot baths   C. eating chicken soup   D. drinking alcohol
60. Some scientists advise you not to take medicine when you have a common cold because _______.
A. your body will fight and kill the virus on its own
B. your body will probably react too much to the virus
C. it will take longer time for your body to get over the virus
D. it will not be able to stop the fever, congestion or runny nose

Moods, say the experts, are feelings that tend to become fixed, influencing one’s outlook for hours, days or even weeks. That’s great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.
Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology（藥理學(xué)）offers a lot of tranquilizers（鎮(zhèn)靜劑）What many people don’t realize, however, is that scientists have discovered the effectiveness of several non-drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don’t head for the drug-store but try the following methods.
Of all the mood-altering self-help techniques, aerobic exercise seems to be the most efficient cure for a bad mood. “If you could keep up the exercise, you’d be in high spirits, ” says Kathryn Lance, author of Running for Health and Beauty.
Researchers have explained biochemical and various other changes that make exercise compare favourably to drugs as a mood raiser. Physical exertion such as housework, however, does little. The key is aerobic exercise—running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body’s use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week.
小題1:What is the main subject discussed in the passage?
A．How to beat a bad mood.B．How to talk bad moods out.
C．How to do physical exercises.D．How to join in aerobic exercises.
小題2:According to the passage, all of the statements are true EXCEPT that       
A．climbing is an efficient cure for a bad mood
B．moods can have a bad effect on people’s health
C．a(chǎn)erobic exercise can help people get rid of bad moods
D．pharmacology has provided people with many tranquilizers
小題3:“Feel out of sorts” in paragraph 2 could best be replaced by “       ”
A．put things in orderB．a(chǎn)re in high spirits
C．a(chǎn)re in a bad moodD．search for tranquilizers
小題4: It can be inferred from the passage that        
A．some drugs are more effective than physical exercises
B．a(chǎn) person does not need aerobic exercise if he is in a good mood
C．the best way to overcome a bad mood is to talk to oneself
D．when in a bad mood, one may not work very efficiently

Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body.
Our bodies use varying（不同程度的） amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight. In order to avoid becoming overweight, it is advisable to eat a balanced diet and not eat too many foods that have a high calorie rating.

Will it matter if you don’t take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains, if a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Contrary to what many people believe, if you don’t eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
77. The results of the test show that ______
A. breakfast has great effect on work and studies.
B. breakfast has much to do with people’s health.
C. a person will work better if he has simple breakfast

“Human influenza viruses can survive and be infectious for several days when they are deposited on banknotes,” according to the latest study by Yves Thomas and his colleages in Switzerland. Scientists put different types of flu virus onto Swiss franc notes and found that they could survive from a few hours to more than a week. The results depended on the type of flu virus.
According to the study, Swiss-banknotes are mostly cotton covered by a nonporous resin(無(wú)孔樹(shù)脂). Banknotes from other countries may be composed of different materials, and this could affect viral transmission. “Whether similar results would be obtained with banknotes from other countries and with different characteristics needs to be studied.” the authors wrote. In an interview with Reuters, Thomas said. “Our studies have convinced us that it is possible to catch the flu from banknotes, but the chances are very, very small and there is no cause for concern among the gneral population,” To be sure, many kinds of frequently touched surfaces could temporarily hide the flu virus. Broadly speaking, scientists consider the risk of transmission in this way to be low. Particularly if hand-washing and other hygiene measures are practiced.
Three things must happen for a flu virus to be transmitted from one person to another via money. First, a person who is infected with the flu virus must sneeze or cough onto the banknote. Next, an uninfected person would need to touch the money while the virus si still present. Finally, that person would need to put his hand in his mouth or pick his nose, says Thomas. The best defense against infection: follow public health guidelines and wash your hands frequently.
49. What does the underlined word “this” refers to in the second paragraph?
A. The time when people stay in a bank.
B. The fact that banknotes may consist of deferent materials.
C. The bank where people draw their money.
D. The country where the banknotes are in circlation.
50. From the last paragraph, we can know that an infected person should ________.
A. pay attention to his personal hygiene    B. wash his hands after leaving a bank
C. be monitored at a bank                D. not cough at a bank
51. What can we learn from the passage?
A. Any person who touches banknotes will become infected.
B. Different flu viruses stay on the surface of banknotes for different lengths of time.
C. The bank should not allow any infected person to enter.
D. Only banknotes in Switzerland can transmit the flu virus.
52. What is the best title for the passage?
A. Is it Dangerous to Stay in a Bank?
B. How to Avoid Being Infected with the Flu Virus?
C. Can You Catch the Flu from Handling Money?
D. Why Do People Refuse to Use Banknotes in Switzerland?

A
The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep color in meats and other food additives（添加劑）caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin (青霉素) to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
51. According to this passage, we can know___________.
A. cancer was discovered in 1945
B. science has made food unfit to eat
C. perhaps most of human illness is caused by what we eat
D. perhaps most kinds of cancer are related to what people eat
52. The additives in food_________.
A. are bright and colorless                   B. have indirect effects on our health
C. have direct effects on our health          D. have direct and indirect effects on our health
53. People use additives_________.
A. to change color of the food               B. to make food more unfit to eat
C. to take off the diseases of the food        D. to improve the color and taste of the food
54. Which of the following is Not true?
A. We needn’t take care of what we eat.
B. Some wrappings of food are harmful.
C. “The practice continues” means “things are still going on like that”.
D. Farmers try to make more money on the market by fattening their animals.

British and American scientists are raising genetically modified(轉(zhuǎn)基因的) pigs in the hope of providing organs for transplant(移植) to humans, the project leader wrote in a newspaper Sunday.
Scientists in London and California have begun conducting the genetic experiments to find a solution to record–long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times.
In Britain alone, around 8,000 patients are waiting for a transplant.
"People needing a new heart or liver are waiting for someone else to die – usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans."
The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital.
Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets(豬仔), adding them to the animal's sperm(精子).
He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate.
The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri.
"Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote.
Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs.
49. Scientists are introducing human genes into the animals to ____________.
A. make the organs healthier
B. reduce the pain of animals
C. make the organs live longer
D. reduce the chances of rejection
50. Some scientists have blamed the idea of using animal organs for human transplant because ____________.
A. the technique is not perfect now
B. humans may be infected with animal viruses
C. it is against laws and regulations
D. it may cause a conflict between humans and animals
51. According to Winston, it seems ___________ to Britain to move the experiments to the United States.            
A. a pity
B. a pride
C. a disaster
D. a good idea
52. It can be inferred from the passage that ____________.
A. animal organs are commonly used for human transplant now
B. lots of patients need animal organ transplants now
C. examples of the animal tissues being rejected have happened
D. it is not safe to use animal organs for human transplant

B
Do you have a sore throat, a running nose and a headache? Do you keep coughing and sneezing? If you do, the chances are that you have a cold or perhaps flu — but which one? Although both colds and flu are caused by viruses, they are very different illnesses.
Colds, which usually last about a week, affect the nose most. They commonly cause a running nose and sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.
Flu is a much more serious illness and is caused by different group of viruses. People with flu usually get all the symptoms described above. However, they also get a high fever, a dry cough and much worse aching. Fever is one of the characteristic symptoms of the flu for all ages. The symptoms also last much longer. Sometimes they don’t disappear for at least two weeks.
Flu can be a deadly disease. The elderly, who are weaker and less healthy than most younger people, can die from flu. This is one reason why old people are advised to have a flu injection (預(yù)防針) before the start of winter when flu is most common. This injection is inexpensive and definitely worth it.
If you have a cold or flu, you must always deal with used tissues (紙巾)carefully. Don’t leave dirty tissues on your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze! You don’t want to see the small drop of liquids blown out of your nose and mouth when you sneeze, do you? Disgusting, eh? Now you can understand why it’s a good idea to cover your nose and mouth when you sneeze!
60. According to the passage, people with colds hardly get _______.
A. a headache               B. a high fever                     C. a running nose          D. aching muscles
61. In paragraph 4, we learn that _______.
A. flu injection can cause death                                 B. most old people die from flu
C. flu is most common in summer                             D. flu can kill old people easily
62. Dealing with used tissues properly is important because _______.
A. it helps keep your classroom tidy                          B. people hate picking up dirty tissues
C. it prevents the spread of colds and flu                       D. picking up lots of tissues is hard work
63. Which of the following statements is true according to the passage?
A. Both colds and flu last the same time.                  
B. Both colds and flu can be prevented by injection.
C. Both colds and flu are caused by the same viruses.
