If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1，000 joggers (慢跑者)and non-joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious injuries.
Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy(寿命), jogging a few times a week at a moderate (适度的)pace is a good strategy. Anything more is not just unnecessary, and it may be harmful.”
The implications (暗示)of this are that moderate forms of exercise such as tai chi, yoga and brisk (轻快的)walking may be better for us than “iron man” events, triathlons and long-distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study, “You don’t actually have to do that much to have a good impact on your health. And perhaps you shouldn’t actually do too much”.

3. According to the scientists, why is too much exercise harmful?

When my friend Lesa was diagnosed(诊断) with cancer, another friend and I went to the hospital to spend some time with her. We bought her a small toy and named him Lemon－Aide. We gave Lemon－Aide to Lesa and told her he was to go with her to all of her treatments to remind her that we were thinking of her and caring about her even though we could not always be with her. When the treatments were completed, she said when someone else needed him she would pass him along.
A few months later，much to my surprise, it was me that she passed him to. Lemon－Aide went with me to all of my treatments.
One day while waiting for my doctor I decided we could market the idea to fight cancer. Lesa thought it was a great idea so we founded the organization that came to be known as Lemon－Aide' s Friends, Inc. We designed our organization to remind people fighting cancer that there are people who love and care about them all the time. Today we have totally 5013 volunteers. The money raised is donated to cancer patients who do not have insurance. The Physicians on our Board of Advisors determine how and where our money is donated.
Lemon－Aide is for men, women, and children of all ages and to date has been sent to 34 states and 33 countries to provide smiling support for people fighting cancer. When life gave us lemons we made lemonade. Lemon－Aide, a soft smiling toy that represents love, support, and encouragement.

People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals(间隔) each day.
Low-calorie Diets Do Not Work
The reason people cannot lose weight by starving themselves is that their metabolism (新陈代谢) will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2,500 calories per day and not gain any weight.
Low-fat Diets Do Not Work
Many people in today’s society are buying mostly low-fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle.
Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.
9. What is the main reason why people are overweight?
A. They burn many calories every day. B. They eat the wrong foods at the wrong time.
C. They eat food with lots of calories. D. They don’t take weight loss pills.
10. The article is written in order to________.
A. tell readers not to buy low-fat or non-fat food.
B.tell readers about an important scientific discovery.
C .tell readers how to lose weight.
D. call on people to lose weight and stay healthy.
11. To realize the aim of your weight loss plan, you should_________.
a. do exercise every day b. eat meals at the right time
c. eat fruits and vegetables d. eat low-fat or sweet food
e. eat the proper foods at each meal
A. a, b, c, e B. a, b, d, e C. a, c, d, e D.a, b, c, d

Health experts have long known that vitamin D is important for healthy bones and teeth. It may also help to protect the body against diseases such as diabetes(糖尿病) and cancer. And now, researchers say vitamin D might help fight brain diseases called dementia (痴呆).
Dementia is a brain disease that damages thinking and memory processes, which scientists call “cognitive (认知) abilities.” Dementia is difficult to treat. Taking care of someone who has dementia is extremely demanding. And the disease is very frightening to sufferers. Chris Roberts suffers from dementia. He says the worst part of living with this disease was getting lost while driving. “The worst thing that I found was getting lost in the car, not just forgetting where I was going— I wouldn’t know where I was.” More than 47 million people around the world suffer from dementia. The World Health Organization reports that 60 percent of them live in low- and middle-income countries.
We get vitamin D from some foods like nuts, lentils (扁豆) and fatty fish. We also get vitamin D from the sun. But that is not dependable. In some parts of the world, there is not enough sunlight to provide enough vitamin D. Also, sunblock prevents the vitamin from entering the body. To add to the problem, the skin’s ability to process vitamin D weakens as a person ages.
Researchers at Rutgers University in New Jersey are exploring the relationship between vitamin D and dementia. The team recently measured vitamin D levels and cognitive ability in older people. Nutritional sciences professor Joshua Miller led the team. He said cognitive abilities differed among the study subjects. He said tests showed that about 60 percent of the group was low in vitamin D.
12. Which of the following is true about vitamin D?
A. Vitamin D can decrease people’s risk of heart diseases.
B. Vitamin D helps the body fight against cancer.
C. Vitamin D is mainly obtained from the sun.
D. The need for Vitamin D decreases as people age.
13. What does the underlined word “demanding” mean in Paragraph 2?
A. Boring but rewarding.
B. Disturbing and frightening.
C. Disgusting and stressful.
D. Hard and tiresome.
14. What does Paragraph 3 mainly talk about?
A. How vitamin D affects people’s health.
B. Where people get vitamin D.
C. Whether sunlight can produce vitamin D.
D. Why people’s age influences the production of vitamin D.
15. Where can we most probably read the passage?
A. In a travel brochure.
B. In a literature magazine.
C. In a science journal.
D. In a commercial advertisement.

How to Be a Good Friend
A good friend，who wouldn’t want one？Ever felt like yours just not good enough but don’t know where to improve？ 16 I used to annoy a lot of my friends before，just for the sake of having fun and from that，I’ve learned how to be a good friend，and stay as a good friend.
Listen.
No one likes being interrupted when they’re talking. So，when someone talks，keep yourself quiet and listen to them，especially if they’re feeling down，you need to be the shoulder for them to cry on. If you have any comment to make，be sure that you word it in a way where you don’t sound too negative. 17 When you just don’t share the same interest or you’re not in the mood to listen to them，politely let them know and ask them to understand.
Always smile.
18 The least you can do is，whenever you see your friends，smile and say hello. That way，if they had a bad day，you can make them feel better with your smile along with your ear，and maybe，you can share something funny to cheer them up.
Don’t ever lie.
Everyone would hate being lied to，especially if it’s by your own friend，so don’t lie！It might seem alright to lie occasionally，but once you lose your friend’s trust，you may lose them forever. 19
Keep secrets.
Make sure you can keep a secret. If not，tell your friends straight away you cannot help yourself when it comes to secrets. Otherwise，when you let them tell you about their secrets and you “accidentally” share it with someone else，you’ll have your friends hating you for the rest of your life. 20 Secrets are not meant to be shared，so don’t even try.
A．Everyone has their bad days，and it’s unavoidable.
B．And that is something you surely do not want to happen.
C．Well，you’ve come to the right place.
D．A few people seem upset at you for being so direct.
E．Otherwise，they may just take it as you are trying to put them down.
F．This same thing happened to a good friend of mine.
G．They’ll probably call you “big mouth”．
