Alzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it.
Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.
There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients.
Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.
The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years.
Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition.
Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future.

The key to reaching or staying at a healthy weight is regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing complicated exercises or going to the gym (體育館) every day. All that matters is that each week you get the right balance of activity, including aerobic (有氧健身法的) strength building, and flexibility (柔韌性) exercise. Make exercise a habit by scheduling some every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day of activity seems like a lot of time. The good news is that it’s OK to divide it into shorter “exercise breaks” throughout the day. Just as you might have a healthy snack to stop yourself getting hungry, exercise snacks can keep energy level high. So get up 15 minutes earlier and do some yoga or other stretching (伸展) activity. Fast walk or jog (慢跑) for 15 minutes at lunch. Do the same thing after school ­­­­­or walk or bike home. Add to that taking the stairs, gym class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
Here are 5 simple ways to make an exercise lifestyle change:
1. Start today. Go outside for a walk.
2. Take the stairs instead of the elevator.
3. Instead of driving, walk or bike to places like school or a friend’s house.
4. Clean your room or wash the car.
5. Limit your time watching TV, using the computer, or playing video games--and when you do play, try some games that get you moving.
小題1: The underlined phrase “exercise snacks” in the second paragraph probably means ________.
A.food eaten before exercise
B.food eaten during exercise
C.shorter “exercise breaks”
D.a(chǎn) new kind of exercise
小題2:Why should we have exercise snacks every day?
A.Because they can stop us getting hungry
B.Because they can keep energy level high
C.Because they can include many kinds of sports
D.Because they are more likely to relate to our daily life
小題3:Which of the following is NOT mentioned in the passage?
A.To go hiking on your holidays
B.To spend less time on computer games
C.To go to school on foot or by bike
D.To do some housework at home
小題4:What will be most probably discussed in the following paragraph?
A.Losing weightB.Good eating habitsC.Exercising your brainD.Outdoors exercise
小題5: What would be the best title for this passage?
A.Regular exerciseB.School exerciseC.Indoors exercise D.Difficult exercises

Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.
The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中風(fēng) ) are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.
Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜 ). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.
67. What is the main cause that people suffer from a lot of new sicknesses?
A. Ancient people did a great deal of physical exercise.
B. People today have a lot of alcohol.
C. People today have more tobacco.
D. Food today is quite different from that of ancient times.
68. Which of the following belongs to the dairy products?
A. Milk             B. Corn     C. Pork            D. Flour
69. New kinds of sicknesses have been found because ________.
A. the human body has changed compared with humans who first appeared on the earth
B. the way we live has changed a little
C. our body can’t deal with the changes in life style
D. the way we live today is proper for the human body
70. According to some scientists, Stone-age people were much healthier than people today because they ate a lot of ________.
A. milk and other dairy products                        B. salt and sugar
C. wild animals, fresh wild vegetables and fruits     D. grain foods

“It’s our tradition to help each other”, added Tenpa, a medical official in neighbouring Madoi County, who said Yushu has always been quick to help other areas in times of trouble. “We have suffered many dangers and each time people in Yushu have sent food and clothes. We are always thankful to them and hopefully we proved it by being the first rescue team to arrive in Yushu after the earthquake.”
The Madoi medical team arrived just hours after the violent 7.1-magnitude earthquake hit Yushu. In two weeks, they have treated at least 1,800 people, while the county has donated 400,000 yuan.
The biggest fear in the earthquake area is the outbreak of diseases. Tenpa said, “Keeping things clean in the shelter is very hard. Even hand washing is almost impossible because of lack of water. Our team is spraying disinfectant (噴灑消毒劑) and we hope that will work.”
After driving for 13 hours with his medical team, Tian Jiancan said he immediately found a 40-year-old who was seriously injured after being trapped in a toppled house. Tian had to operate on the man in his emergency medical van. “If we had been one hour later, he would probably be dead. It’s good to see him out of danger now.” Tian’s medical team has treated over 3,200 people, including a 15-day-old baby and a 105-year-old man. They also helped to put up tents against winds, where patients are protected well.
One local man said although most doctors cannot speak Tibetan, they have shown their care and love through their actions.
60. Which of the following is TRUE according to the passage?
A. This is the first time that Tibetans have faced great dangers.
