“I Love You”Virus
On May 21,1999,some American scientists were working at the computers to look for information they needed.Suddenly they saw a lot of very bright red spots crossing the computers’screens.At the same time the computers were working much slower.To find out what was happening they stopped their work to check some parts of the computers.To their horror,they found out that most of their stored information was got rid of by computer virus! Obviously all these computers had been infected by computer virus.
It is said that the computer virus was made by two or three Philippine young men fond of playing tricks.They all had excellent education.They created the virus just to show their intelligence.The kind of computer virus is named“I Love You”Virus.This virus can hide in computers for long.When the time comes it will attack the computers by lowering the important functions,damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store;even worse,it still can reproduce itself in great quantities within a short time.
We come to know that “I Love You”Virus often attacks computers on Mondays and that it is spreading to many computers in the world.Among the countries that suffered computer viruses last year are Britain,Australia,Switzerland and the US.Those who made the computer viruses have been found out slowly and carefully.But till now,how to get rid of the terrible viruses remains a problem.

Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow?moving. There are some aspects(方面) of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.
　　For those who do not particularly enjoy competitive sports — and it is especially difficult to do so if you are not good at them — there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.
　　Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only half way to good health, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (諷刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity?physical effort on the one hand and relaxation on the other — which were the natural way of life of our forefathers.
12. Pollution, noise and stress are examples of _____.
A. causes of unfitness
B. bad features of living in towns
C. the things we can completely do away with
D. unavoidable things in town
13. We don’t get much out of separate sports because we _____.
A. don’t do them very often 
B. don’t do them actively enough
C. find it hard to get out of our armchairs
D. don’t find them interesting
14. To be healthy we must _____.
A. keep fit and active                                      B. keep fit and learn to relax
C. be active and practise Yoga                               D. have a sound mind
15. Our forefathers were healthy because______.
A. their way of life closely connected with both exercise and relaxation
B. they were careful to get plenty of fresh air
C. they spent most of the time out of doors
D. their environment was not polluted

Most of us think that when we step under a shower we’re getting clean．We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about．
A showerhead carries thousands of bacteria (細(xì)菌) called Mycobacterium．These can cause problems like coughs and tiredness, and a general feeling of poorliness (身體不舒服)．When you turn on the water, the bacteria go from the showerhead onto and into your body．
This is a finding of Norman R．Pace and his team at the University of Colorado, in the US．The scientists investigated bacteria in all kinds of human environment, including showers．
Pace's team looked at 45 showerheads in nine American cities．They discovered that 30 percent of them had large amounts of flying Mycobacterium．
But Pace said that they pose few threats to the health．Only those with a frail (脆弱的) immune (免疫的) system might need to worry．
He told the New York Times that the bactertia are not as unpleasant as might be thought．He said that having a shower is no more dangerous than anything else we do in the morning．
But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice．
Let the water run for 30 seconds before getting into the shower．Why? The number of bacteria is smaller than when the water is just turned on．If that seems like a waste of water, he added that you could also change your showerhead every few months．
But Pace had good news too．He has also been testing the air in US subways．Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh．The reason is that a train’s movement pumps fresh outdoor air into the tunnels(隧道)．
Pace explained that he wanted to understand the natural microbial(微生物的) environments of public places．This kind of knowledge might help detect the microbes to be used in a bioterrorist (生物恐怖分子) attack．
49．According to the finding of Norman R．Pace, after taking a shower, we might ______．
A．get much dirtier                B．be covered by bacteria
C．get a frail immune system      D．catch a cough or feel tired
50．Pace’s research into showers shows that ______．
A．there is no reason to fear microorganism
B．shower water contains much less bacteria after being left to run for 30 second
C．having a shower in the morning is more dangerous than at other time
D．of 45 showerheads surveyed in nine cities, 30 carried large amounts of Mycobacterium
51．According to the research of Pace’s team, which of the following contributes to fresh air in US subways?
A．Train wheels．               B．Iron particles．
C．The movement of the trains． D．Air conditioners on the trains．
52．The word “detect” in the last paragraph probably means “______”．
A．to discover      B．to protect        C．to make   D．to prevent

And adolescents who slept five hours or less a night were 71 percent more   15  to suffer depression and 48 percent more     16  becoming suicidal, the study said.
"It is a common perception and societal   17  that adolescents do not need as much sleep as pre-adolescents, yet studies suggest that adolescents may  18  require more sleep," said Gangwisch.

People Born in Autumn Live Longer
People born in the autumn live longer than those born in the spring and are less likely to fall chronically ill when they are older, according to an Austrian scientist.
Using census（人口普查）data for more than one million people in Austria, Denmark and Australia, scientists at the Max Planck Institute in the northern German town of Rostock found the month of birth was related to life expectancy（預(yù)期壽命）over the age of 50. Seasonal differences in what mothers ate during pregnancy, and infections occurring at different times of the year could both have an impact on the health of a new-born baby and could influence its life expectancy in older age. “A mother giving birth in spring spends the last phase of her pregnancy in winter, when she will eat less vitamins than in summer,” said Gabriele Doblhammer, one of a team of scientists who carried out the research. “When she stops breast-feeding and starts giving her baby normal food, it’s in the hot weeks of summer when babies are prone (易于)to infections of the digestive system.” In Austria, adults born in autumn (October-December) lived about seven months longer than those born in spring (April-June), and in Denmark adults with birthdays in autumn outlived those born in spring by about four months. In the southern hemisphere, the picture was similar. Adults born in the Australian autumn—the European spring—lived about four months longer than those born in the Australian spring. The study focused on people born at the beginning of the 20th century, using death certificates and census data. Although nutrition at all times of the year has improved since then, the seasonal pattern persists, Doblhammer said.
But on the other hand, according to a study of more 40,000 people, those born in spring and summer report themselves luckier than those born in autumn or winter. Professor Richard Wise-man who led the research explained that the temperature at the time of birth might influence the development of the brain and seasonal factors make a difference as well.
小題1:The underlined word “outlived” in the text probably means ________.
A．lived out ofB．depended on
C．had a shorter life thanD．lived longer than
小題2:The census data of the following countries is used for research EXCEPT _______.
A．Germany.B．Denmark.
C．Australia.D．Austria.
小題3:What’s the main idea of this text?
A．Nutrition at all times of the year has improved since the beginning of the 20th century.
B．In Austria, adults born in autumn (October—December) lived about seven months longer than those born in spring (April—June).
C．People born in autumn live longer than those born in spring and are less likely to fall ill when they are older.
D．Babies are prone to infections of the digestive system.
小題4:Which of the following is NOT true according to the text?
A．Infections occurring at different times of the year influence the health of a new-born baby.
B．The study focused on people born in the late 20th century.
C．A mother giving birth in spring eats less vitamins during the last phase of her pregnancy in winter.
D．What mothers ate during pregnancy could have an impact on the babies’ life expectancy in older age.
小題5:The right sentence of the following is ________.
A．The month of birth was not related to life expectancy over the age of 50.
B．A mother giving birth in spring spends the last phase of her pregnancy in winter, eating more vitamins than in summer.
C．Stopping breast-feeding and starting giving babies normal food must make babies prone to get infected with the digestive system in the hot weeks of summer.
D．Adults born in the Australian autumn―the European spring―lived about four months longer than those born in the Australian spring.

The United Nations Children’s Fund (UNICEF) has declared October 15 as Global Handwashing Day in 2005．The first Global Handwashing Day is on October 15 of 2008.Activities are planned over twenty countries to get millions of people in the developing world to wash their hands with soap. Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the UN Children's Fund, American government agencies, the World Bank and soap makers Unilever and Procter and Gamble. The goal is to create a culture of hand washing with soap.
Hand washing can prevent the spread of disease. Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.
The organizers say all soaps are equally effective at removing disease-causing germs. The correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds.Then, rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air. Soap is important because it increases the time that people spend washing. It also helps to break up the grease and dirt that hold most of the germs.And it usually leaves a pleasant smell,which increases the likelihood that people will wash again.
Washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea(痢疾) by almost half. And it could reduce deaths from pneumonia and other breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than one and a half million children a year. Pneumonia is the leading cause, killing about two million children under five each year. Hand washing can also prevent the spread of other diseases.
50.We can learn from Paragraph 1 that _______.
A.the first Global Handwashing Day was held in 2005
B.many originations support the idea of Global Handwashing Day  
C.Global Handwashing Day was founded by many soap makers
D.the content of Global Handwashing Day is to wash your hand frequently
51.The underlined phrase “critical moments” in Paragraph 2 refers to _______.
A.the turning points    
B.schedules  
C.the arrangement of a time
D.the necessary parts in health
52.The main purpose of the story is to tell us ________.
A.hand washing is very important
B.to create a culture of hand washing with soap
C.germs can infect ourselves and others
D.soaps play an important role in everyday life
53.The last paragraph implies that ___________.
A.a soap is a kind of medicine to prevent a disease
B.it is important for children to wash hands in a correct way
C.Pneumonia kills about two million children each year
D.Diarrhea is the second leading cause of child deaths.

Violent gangs. Bar fights. Broken bones. No, we aren’t talking about a late night in Downtown Chico; we’re talking about the things that come to many people’s minds when the word, motorcycle, is mentioned.
Many Chico State students have learned of the convenience of small motorcycles and scooters when it comes to parking on or near campus. Motorcycle parking is something that is available when compared to the amount of vacant automotive parking—something especially valuable when running a bit late for class. Motorcycle-riding students have also learned to appreciate the 50 to 80 average miles per gallon, especially today when it seems as if gasoline prices are shooting up faster and more often than a back alley addict.
Still, some people are reluctant to ride the steel horse. Marc Lewis, a 24-year-old Chico State anthropology student, is one of those people. “I’ve had motorcycles in the past. I know what they’re about. I want another one, for recreational purposes,” Lewis said. The only things holding Lewis back are insurance costs and what he refers to as “unsafe drivers”. Safety and insurance costs certainly are important factors.
Chris Kelley, employee of Cost-U-Less Insurance Center at 166 Cohasset Road, Suite 3, admits that motorcycle insurance can get pricey. The average price per month for Chico State students in their 20s is about $100, Kelley said. “The most expensive rate I’ve ever charged was something like $32,000 a year,” Kelley said. “The guy had a horrible record.”
If a motorcycle is something that you’ve always been curious about but have been frightened by the dangerous image it is often given, try rethinking your position. Motorcycling is one of the most diverse activities in existence. Consider the information you find here a brief introduction to several of the more popular aspects of motorcycle riding.
44. When it comes to motorcycles, one tends to think of ____.
A. a late night in Downtown Chico           B. the horse made of steel
C. the money paid for insurance               D. a horrible image motorcycles give
45. According to the second paragraph, which of the following is NOT true?
A. It is very convenient for students to ride motorcycles.
B. The campus has enough parking place for motorcycles.
C. Students are often late for class riding motorcycles.
D. Motorcycles consume less gasoline.
46. Why are some people unwilling to ride the steel horse?
A. Because they often have their bones broken.
B. Because they are worried about the costly insurance and safety problems.
C. Because they have to pay for the pricey gasoline.
D. Because they don’t want to ride it for entertainment.
47. The writer intends to tell us in the last paragraph that ____.
A. we shouldn’t buy a motorcycle due to the danger it causes
B. many people are frightened by the dangerous image
C. we shouldn’t be curious about the motorcycle any more
D. motorcycles are still popular regardless of the disadvantages

Ⅲ 閱讀（共兩節(jié)。滿分40分）
第一節(jié)閱讀理解（共15小題；每小題2分，滿分30分）
閱讀下列短文，從每題所給的A、B、C和D項(xiàng)中，選出最佳選項(xiàng)，并在答題卡上將該項(xiàng)涂黑。
A
Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (營(yíng)養(yǎng)) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白質(zhì)) , like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (維他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality. Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (壽命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
41. According to the passage,_________.
A .we should always keep fit
B. if we were healthy, we could spend our days in doing things with less sleep
C. one can eat a lot to stay in good shape
D. one needn't take any exercise if he is healthy
42. In order to keep good health, ___________ .
A. we should eat a lot of sweets      
B. one needs a large amount of fat
C. people should eat according to the foods nutrition
D. we must try to sleep now and then
43. Eating more and sleeping less________.
A. can keep healthy                 B. is no good for you
C. gets you more energy           D. will keep your personality
44.The writer explains ________in this passage.
A. how to eat                         B. the importance of doing exercise
C. how to keep healthy             D. what to eat
45.The title of the article should be___________ .
A. Eating and Exercising           B. How Vitamins Work in Man's Body
C. Staying Healthy                   D. Sleeping Well
