People believe that climbing can do good to health. Where can you learn the skill of climbing then If you think that you have to go to the mountains to learn how to climb, you're wrong. Many Americans are learning to climb in city gyms. Here, people are learning on special climbing walls. The climbing wall goes straight up and has small holding places for hands and feet.
How do people climb the wall To climb, you need special shoes and a harness (保护带) around your chest to hold you. There are ropes tied to your harness. The ropes hold you in place so that you don't fall. A beginner's wall is usually about 15 feet high, and you climb straight up. There are small pieces of metal that stick out for you to stand on and hold on to. Sometimes it's easy to see the new piece of metal. Sometimes, it's not. The most difficult is to control your fear. It's normal for humans to be afraid of falling, so it's difficult not to feel fear. But when you move away from the wall, the harness and the ropes hold you, and you begin to feel safe. You move slowly until you reach the top.
Climbing attracts people because it's good exercise for almost everyone. You use your whole body, especially your arms and legs. This sport gives your body a complete workout. When you climb, both your mind and your body can become stronger.
1．What can we infer from the passage

The spread of Western eating habits around the world is bad for human health and the environment. These findings come from a new report in the journal Nature.
David Tillman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how diet affected health. He noted a movement beginning in the 1960s. He found that as nations industrialized, population increased and earnings rose, more people began to adopt what has been called the Western diet. The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tillman says overweight people are at greater risk of noninfectious diseases like diabetes (糖尿病) and heart disease.
Unfortunately, if people adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia. China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as it began to industrialize over a 20 year period. And that is happening all across the world, in Nigeria and so on.
And, a diet bad for human beings is also bad for the environment. As the world's population grows, more forests and tropical areas will become farmland for crops or grassland for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now.
Mr. Tillman calls the link between diet, the environment and human health, “a dilemma”， a problem offering a difficult choice. He says one possible solution is leaving the Western diet behind.
6．David Tillman believes that ________．
A．diet, the environment and human health are closely connected
B.the Western diet is the only choice as nations industrialized
C.people in tropical areas are more likely to have heart disease
D．traditional diet is more balanced than the Western diet
7．According to the passage, more greenhouse gas might be given off in the future from ________.
A．transportation
B．developing countries
C．agriculture
D．developed countries
8．What can be inferred from the passage
A．Nigeria has the largest number of diabetes cases.
B．Overweight people are at higher risk of infectious diseases.
C．The examined information comes from developing countries.
D.Industrialization contributes to the spread of the Western diet.
9．What's the author's purpose of writing the text
A．Call on us to protect the environment.
B．Warn us of the danger of the Western diet.
C．Remind us of the importance of health.
D．Advise us to have a balanced diet.

What's your opinion on spicy food Some people cannot handle even the smallest amount of the chili (辣椒)in their dinner while others can't get enough of it.
Scientists have long been puzzled by why some people love chilies while others loathe them. Plenty of research has been done on the subject, dating as far back as the 1970s. Previous results showed that a love of chilies is related to childhood experiences, and cultural influences affect our taste buds, too. But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else, CBC News reported.
“We have always assumed that liking drives intake—we eat what we like and we like what we eat. But no one has actually directly bothered to connect these personality traits (特点) with the intake of chili peppers，” said Professor John Hayes from Pennsylvania State University, who led the study.
But before you look at the study, you should first know that “spicy” is not a taste, unlike sour, sweet, bitter and salty. It is, in fact, a burning sensation that you feel on the surface of your tongue. This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrills, something they usually get from watching action movies or riding a roller coaster.
In the study, 97 participants, both male and female, were asked to fill out questionnaires about certain traits of their personalities, for example, whether they like new experiences or tend to avoid risks. They were then given cups of water with capsaicin, the plant chemical that makes chilies burn, mixed into them.
By comparing the answers to the questionnaires and what participants said they felt about the spicy water, researchers found that those who were most tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.
Interestingly, we used to believe that the reason why some people can withstand spicy food is that their tongues have become less sensitive to it. However, this latest study has found otherwise.“It's not that it doesn't burn as badly, but it's that you actually learn to like the burn，” explained Hayes.
1．What's the meaning of the underlined word “loathe” in the second paragraph
A．Dislike. B．Fear.
C．Put up with. D．Adapt to.
2．What did Professor John Hayes and his team discover from their study
A．What we eat actually helps to develop our personalities.
B．Males are more likely to enjoy spicy food than females.
C．Those trying to avoid risks tend to be less interested in spicy food.
D．People are wrong to treat spicy as a kind of taste rather than a feeling.
3．Why do some people like spicy food according to the recent study
A．Because their taste buds have become less sensitive.
B．Because they love the burning sensation.
C．Because they want to challenge themselves.
D．Because the more they try spicy food, the less it burns.
4．What's the main idea of the passage
A．His or her parents' diets decide his or her personality.
B．The latest study shows whether a person enjoys spicy food largely depends on his or her personality.
C．His or her childhood experiences decide his or her personality.
D．His or her cultural background decides his or her personality.
B
If you are overweight, you should watch your diet carefully in order to keep fit. The best way to do this is to start a weight control program. At first it is wise to talk with your doctor. He can advise you of the number of calories you should have in your meals each day. He can tell you about exercising while you are on a diet. A good rule is to lose slowly. A loss of a pound or two is plenty.
Plan meals around foods you know. This means that it is wise to include foods that you are used to and that are part of your regular eating habits. When you have lost the weight you wish, simple items can be added to your diet so that you can maintain the weight you want. While you are dieting, try to build a pattern of eating that you can follow later to maintain your weight.
When dieting, choose low calorie foods. Avoid items such as fats, fried food, sweets, cakes, cream and soft drinks. Try to take coffee and tea without sugar or cream. Snacks can be part of your diet. For example, a piece of fruit or a simple dessert saved from mealtime can be eaten between meals.
Keep busy! This way you will not be likely to go off the diet. Make full use of chances to exercise. Try walking instead of riding whenever possible. Happy dieting!
5．What does the passage mainly talk about
A．How we should diet.
B．Why we should diet.
C．When we should diet.
D．Whether we should diet.
6．What does the writer advise us to do

For the past 17 years my life was very happy. Then the first sad thing happened. My mother became very ill, and soon she knew that she was dying. Just before she died, she asked Elizabeth and me to go to her room. She held our hands and said, “Victor and Elizabeth, my children, I'm very happy because you love each other, and because one day you'll get married. Everyone in the family loves you, Elizabeth. Will you take my place in the family, my dear I can die happily if you look after them when I have gone.”
My mother died and we were very sad, because we loved her dearly. Elizabeth was brave and helped us; her sweet smile gave us some happiness in the unhappy days after my mother's death. The time came for me to go to university. I didn't want to leave my sad family, but we all knew that I should go. It was hard to leave, too, because the parents of my good friend Henry would not let him go to university with me. So I had to go alone.
On my first day at university I met my teacher, Professor Waldman, who was one of the greatest scientists in the world. He gave a wonderful talk to all the students who were starting at the university. He ended his talk by saying, “Some of you will become the greatest scientists of tomorrow. You must study hard and discover everything that you can. This is why God made you intelligent—to help other people.”
After the professor's talk, I thought very carefully. I remembered the storm when I was 15; I remembered how the lightning had destroyed the trees. From then on, I wanted to use electricity to help people, and I wanted to discover the secret of life. I decided to work on these two things.
I started to work the next day. I worked very hard and soon Professor Waldman and I realized that I could learn to be a very good scientist.
The professor helped me very much, and other important scientists who were his friends helped me, too. I was interested in my work and I did not take one day's holiday during the next two years. I did not go home, and my letters to my family were very short.
After two years, I had discovered many things and I built a scientific machine that was the best in the university. My machine would help me answer the most important questions of all. How does life begin Is it possible to put life into dead things To answer these questions about life, I had to learn first about death. I had to watch bodies from the moment when they died and the warm life left them. In the hospital and in the university, I watched the dying and the dead. Day after day, month after month, I followed death, so it was a dark and terrible time.
I built a tall mast about 150 meters high, which was higher than the tallest building in the city, to catch lightning and send the electricity down to my machine in the lab. I believed I could use that electricity to give life to things that were dead.
Then one day, the answer came to me. Suddenly I was sure that I knew the secret of life.

What do you want to be when you grow up A teacher A doctor How about an ice cream taster
Yes, there really is a job where you can get paid to taste ice cream. Just ask John Harrison, an “Official Taste Tester” for the past 21 years. Testing helps manufacturers (制造商) to be sure of a product's quality. During his career, Harrison has been responsible for approving large quantities of the sweet ice cream—as well as developing over 75 flavors.
Some people think that it would be easy to do this job; after all, you just have to like ice cream, right “No—there's more to the job than that，” says Harrison, who has a degree in chemistry. He points out that a dairy or food science degree would be very useful to someone wanting a career in this “cool” field.
On a typical morning, Harrison tastes and assesses 60 ice cream samples. He lets the ice cream warm up to about 12 ?. Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice cream soup.”
While the ice cream warms up, Harrison looks over the samples and grades each one by its appearance. “Tasting begins with the eyes，” he explains. He checks to see if the ice cream is attractive and asks himself, “Does the product have the color expected from that flavor？” Next it's time to taste!
Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy—working at one cool job.
5．What is John Harrison's job
A．An ice cream manufacturer.
B．An official.
C．A teacher.
D．An ice cream taster.
6．According to John Harrison, to be qualified in the “cool” field, it is helpful to ________．
A．keep a diary of work
B．have a degree in related subjects
C．have new ideas every day
D．find out new flavors each day
7．What does Harrison do first when testing an ice cream
A．He tastes the flavor of the ice cream.
B．He examines the color of the ice cream.
C．He lets the ice cream warm up.
D．He stirs the ice cream.
8．Which of the following is probably the best title for the passage
A．Tasting with Eyes
B．Flavors of Ice Cream
C．John Harrison's Life
D．One Cool Job
C
How often do you exercise A new study finds that most kids aged 12 to 15 aren't getting enough physical activity. The results are based on about 800 kids. As part of the study, the young teens tracked and reported on their own activity levels, and took physical exams.
The US fitness guidelines recommend an hour or more of physical activity every day. According to the study, only 1 in 4 kids in the US get enough physical activity.
“It's certainly very worrying to see that our kids are engaging in such a limited amount of physical activity each day，” said Dr. Stephen Pont. He is an expert on children's health.
Few kids in the survey met the guidelines for physical activity that raises the heart rate and makes them breathe harder. Overall, about 25% said they got an hour of that kind of violent exercise every day. Kids also reported on which activities they did most often outside of the school gym class—basketball for boys and running for girls.
The study found that obese (肥胖的) teens were less active than normal weight girls and boys. Overweight girls were slightly less active than normal weight girls, but levels were similar among overweight and normal weight boys. The study also said that the overall obesity rate for children aged 2 to 19 is 17%, or about 12.5 million kids.
