Vaccines battle diseases caused by bacteria and viruses. A weakened form of the germ is introduced into the body. The body makes special substances called antibodies to fight the germs. If the actual germs were to attack, the antibodies would fight them.
Because there are many kinds of flu viruses, scientists must create a new vaccine formula (配方) each year. Researchers must make a prediction.
“The flu vaccine is not as effective as the polio (小儿麻痹症) vaccine or the measles(麻疹) vaccine,” says Dr. William Schaffner of Vanderbilt University School of Medicine.
“It’s not a great vaccine, but it is quite a good vaccine.”
But a flu vaccine doesn’t work for everyone. There are certain people who should be careful about taking it. Because the vaccine is produced from eggs, those who are allergic (过敏的) to eggs should not take it. If you have a fever, you should wait until you recover.
Some people are afraid that they might get the flu from the flu shot. Scientist say that it is not possible, because the viruses in the flu shot are inactivated (灭活的). But some minor side effects such as low-grade fever and body aches could occur. If they do, they begin soon after the shot and usually last only one to two days.
60. What is an antibody?
A. An antibody is a vaccine formula
B. An antibody is a germ that is introduced into the body
C. An antibody is a vaccine that fights diseases.
D. An antibody is a special substance to fight germs.
61. Which of the following statements is NOT true?
A. Not everyone is suitable for the flu vaccine.
B. The flu vaccine is not so effective as the measles vaccine
C. Flu viruses create new vaccine formulas each year.
D. People can’t take the flu vaccine at anytime.
62. It can be inferred from the text that _____.
A. scientists should change the vaccine formula each year
B. vaccines can battle diseases caused by bacteria and viruses
C. all children ages 6 months through 18 years can receive the flu vaccine
D. scientists are responsible for the side effects of the flu vaccine
63. Which of the following would be the best title for the text?
A. The flu vaccine B. Side effects of the flu vaccine
C. How to prevent the flu D. Not everyone can get the flu shot

For example, if you force yourself to smile or laugh, even when you don"t feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude.

First it was jogging. Then aerobics（有氧运动）. Not too long ago, Americans discovered race walking.
Now Americans are into a new fitness craze. They’re taking up bicycling. Over hills and down mountainsides and across quiet country roads, Americans are busily rolling along.
The number of adults who ride for fitness is around 17 million, an increase of 70 percent over four years
ago. Twice as many women as men are coming to the sport. Americans are falling in love with biking because it has speed, the benefits of jogging and beautiful scenery.Bicycling is a very appropriate sport, which is important to people who injured their knees while jogging or whose joints are aching from aerobics. And biking is a real awakening for people who have been into race walking in the past. Race walking is as dull as watching paint dry.
The most popular kind of bicycle for people who are new to the sport is the mountain bike, which has a fixed frame with wide tires and upright handles. Mountain bikes also have many gears（齿轮） to make it easier to climb hills. About 5 milli
on Americans ride mountain bikes, compared with 200,000 who rode them only five years ago.Costs range from about ＄130 for a bottom-of-the-line bicycle to more than ＄2,700 for an expensive bicycle.
Mountain biking has attracted some people who race down the sides of mountains like a bat out of hell. But most riders ride slowly and they rarely venture far from home.
The biking craze has brought an unexpected profit（盈利） to clothing and bicycle accessory（附属品）makers. Last year, bikers paid ＄630 million for biking clothes and accessories.
Bicycling seems likely to continue its fantastic growth.

Fred Michel is one of 7.2 million Americans who moonlight, or hold more than one job.
Once a week, after his day job as medical director of a mental health center, the 40-year-old psychiatrist (精神病大夫) heads to a part-time job at a treatment center for young people. Twice a month, he travels three hours to another teenage treatment center.
Last year, 5.4 percent of the American workforce held second jobs, accord
ing to the US Labor Department, and that looks set to increase this year.Many workers like the safety that moonlighting provides, says Carl Hausamn, the writer of "Moonlighting: 148 Great Ways to Make Money to the Side."
The information from the US Labor Department shows that 40 percent of US moonlighters in 1997 took a second job to meet household expenses or pay off debts. Others save money or buy some special things.
People also take second jobs with an eye to the future - wanting to try out a new field or gain experience.
Michel started moonlighting when medical systems were unstable (不稳定的). He wanted to make sure he wasn"t tied to one system that ended up failing.
Just as the purposes for moonlighting vary, the moonlighters cross all age and racial groups. And they work in a variety of industries - no longer just service, office and sale jobs.
“Technology just affects your ability to make money,” Hausman says. "That makes a frequent change in moonlighting."
As its name means, moonlighting still occurs mostly at night. And that results in some pressures. Chief among them is time.
Full-time employers could misunderstand, too. Some companies do not allow after-hour work because they fear it will affect their employees" 9-to-5 performance.
"The primary employer is saying, ‘Wait, I"m paying you for the sharp, fresh, energetic you,’” says Tom Gimbel, president and founder of LaSalle Staffing in Chicago. "If you" re burning yourself at both ends, it"s going to show."
Still, the good done to the moonlighters can be great. Besides extra income, moonlighters enjoy variety, freedom and chance to do something new. They also may find their part-time jobs strengthen what they do full time.
Besides, "it"s fun," Michel says. Not only do his part-time jobs offer a chance to network, stretch his professional skills and make more money, but they also give him the variety he wouldn"t find just in a full-time job.
"It" s a way of pulling from the spice cabinet" he says, "and offering a little variety throughout the day."
60. What is the article mainly about?
A. The ways of moonlighting.
B. The reasons for moonlighting.
C. The problems with moonlighting.
D. The kinds of people who moonlight.
61. The reason why Fred Michel began to moonlight is that ________.
A. he found it exciting to do a part-time job
B. he needed to make ends meet with more money
C. he feared he would lose his present job one day
D. he felt more and more pressure from his employer
62. Some companies don"t allow their workers to moonlight because they are afraid ________.
A. their workers can not do extra-hour work for them
B. their workers will be too tired to try their best at work
C. their workers will one day turn to some other different jobs
D. their workers will not get to work and be off work on time
63. The underlined sentence "It"s a way of pulling from the spice cabinet." in the last paragraph means _________.
A. moonlighting gets you away from the job you don" t enjoy
B. moonlighting offers you freedom to make extra money
C. moonlighting strengthens your p

Babies are born yogis（瑜伽练习者）．Once we were all able to pull our toes up by our ears and laugh about it．Then we aged, got injured, and began carrying stress in our shoulders and back．In short, we lost our balance．
Yoga（瑜伽） is an ancient practice that helps create a sense of union in body, mind, and spirit．It brings us balance．I was seriously out of balance when I started practicing yoga in 1999．I had plantar fascitis（足底筋膜炎）in both feet, and my doctor had warned me against all the things I loved to do: walking, hiking, and playing tennis．I was desperate for exercise．Yoga became my salvation and even enhanced my other fitness activities．I practice yoga at least twice a week, but I consider yoga to be part of my daily life because after a while you no longer just practice yoga—you love it．
Yoga becomes part of your physical life．Your body grows stronger, more toned, and more flexible as you move from one pose to the other．I spent a week in Mexico at a yoga retreat, and it was the first vacation on which I lost weight．“Rather than building muscle, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of the K．I．S．S．Guide to Yoga．“Because yoga helps maintain a balanced metabolism （新陈代谢), it also helps to regulate weight．Additionally, yoga stretches muscles lengthwise, causing fat to be removed around the cells．” I do yoga poses throughout the day．After hours at my computer, I stretch my stiff shoulders and arms．When I need a boost of energy, I do energizing poses．When I am feeling exhausted at the end of the day, I do restorative poses．
Yoga becomes part of your mental life．Yoga teaches you to focus on breathing while you hold the poses．This attention to breath is calming; it dissolves stress and anxiety．I use yogic breathing on the tennis courts, in the dentist’s chair, and in traffic jams．You should always leave a yoga practice feeling energized, not tired．If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses．In yoga, you “surrender” to the pose by letting go of the tension．
Yoga becomes part of your spiritual life．Yoga is practiced by people from all religions; it is not restricted to any religious group．Yoga teaches “right” living in how we deal with ourselves and others．As I work on a difficult pose, I learn patience, forgiveness, and the value of gentleness．Yoga advocates proper eating, but you don’t have to be a vegetarian to practice yoga．72．What would be the best title for this passage?

Burn Calories in Your Sleep?
The weight-loss world is full of assertions（断言）, rarely proved, that some pill can help you “burn calories while you sleep.” But a recent Dutch study reports that it can be done – simply by eating more lean protein（无脂肪蛋白质）.
Researchers report for the first time that consuming nearly a third of daily calories as lean protein – for example, lean meats without the skin – speeds up a person’s metabolism（新陈代谢） during sleep and that higher protein intake increases the burning of calories and fat during the day. Plus, when the study’s participants, who were all women of healthy weight, ate more protein, they felt fuller, more satisfied and less hungry than when they consumed a diet with the amount of protein, about 10 percent of calories.
The findings suggest that adding lean protein to your daily food “enables you to reach the same level of satiety（过饱）that you are used to with about 80 percent of your normal energy intake,” notes Margriet Westerterp-Plantenga. “That means you can eat about 20 percent less and still have the same satiety.”
What gives protein its caloric edge? It’s more difficult for the body to metabolize protein than either fat or carbohydrates（糖类）. The body also doesn’t store protein as efficiently as it does carbohydrates or fat. So protein is more likely to be burned and that in turn requires more oxygen and helps you feel satisfied in the hours after eating.
But the latest findings don’t mean it’s time to dust off those high-protein diet books. The current study limited fat to about 30 percent of daily calories, and included 40 percent of calories as healthy carbohydrates, including fruit and vegetables. For example, lunch included bread, soy milk, fruit yogurt, tuna in water, tomatoes, cucumbers, feta cheese and salad dressing.
54. According the first paragraph, we know that ______.
A. there’re few studies on weight-loss in the world
B. many studies on weight-loss only cheat customers
C. only few studies are useful for weight-loss
D. there’re few studies about lean protein
55. According to the passage, lean protein can help burn calories while you sleep because ______.
A.it can slow down a person’s metabolism
B. it’s difficult for the body to metabolize
C.it will not make you feel full
D. it’s easy to be stored in the body
56. The underlined phrase “dust off” in the last paragraph means ______.
A. get rid of B. put away
C. get ready to rewrite D. get ready to reuse
57. The passage is mainly to tell readers ______.
A. there is a good diet for weight-losers
B. you can burn your calories in your sleep
C. high-protein diet books will be popular
D. choosing right food is of great use
