Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult, normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socializing, he added, "It's not just a sedentary (久坐的) lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said,"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.
1.What information can we get from the first two paragraphs?
A.Brown fat stores calories and makes us fatter

A.Levels of brown fat can be increased by socializing.
B.The mice lacking social life lose more weight.
C.The research findings haven't been published so far.
D.Dr Matthew During wasn't convinced of the result.
3.We can conclude from the text that _______.

B.a sedentary lifestyle and high calories foods influence people's social life
C.surfing the Internet may influence people's face-to-face communication

B. Pet keeping has a very long history
C. Pet-keeping may do hard to animals
D. People keeps pet for their aesthetic need
E. Caged pets become increasingly popular
F. Pet-keeping is helpful for children’s growths
1.___________
Pet-keeping is a time-honored tradition. One of the reasons for people to raise to raise dogs or cows was usefulness. While people in the past hunted animals and kept them in their backyards, the civilized man today is less cruel towards them and is less exploitative(利用的).
2.___________
We keep animals as pets because they are attractive. We all have the urge to possess something that has aesthetic value, and that is why we treasure paintings or fine furniture. Keeping pets is one form of this urge. A Siamese cat in the house can be a decorative objective. Pets are playful animals and they amuse us. A little rabbit amuses us by its playful and lively runs.
3.___________
Many parents find it helpful to have pets in their house and for their children. Having pets is an excellent way of developing in children the love of animals and responsibility. Children get the opportunity to take on full responsibility for another creature’s life. It will be an educational experience for a child to watch the natural life cycle of an animal. There are psychological benefits for children. Pets are welcome friends for children who are lonely. Pets are excellent companions. Keeping pets means giving love and being loved. We find comfort in giving care and receiving care in return. We get pleasure from their appreciation and their behavior.
4. ___________
As more people move into apartments, there are limitations on keeping of animals like dogs and monkeys. Therefore, caged animals have increased in popularity. Birds fall into this type. We keep them for their beautiful songs and feathers. Fishing keeping is a widespread hobby and the keeper can observe their behavior in the glass tank and study its entire life cycle. The cat is a fine house pet and it fits neatly into human habitation(居住地) without requiring its own cage. They are wonderful hunters, if there are rats around.
5.___________
Pets satisfy man’s desire to care for a bit of nature. The pet owner has the responsibility for supplying those needs nature provides. Pets are amusing and entertaining, but we are in a way doing animals harm by making them live in a human environment. Are we not enslaving(奴役)them?

University — the best days of my life! I made lots of friends in my student dorm, went to great parties, joined the debating society... and, well, I did some work too — but I must admit that my lecturers were very patient with my tardiness (拖沓).
It is easy to look back at our university days in good ways but the truth is that when we first arrived on campus, most of us were out of our comfort zone. In fact, a survey of students at Imperial College London has showed that 3 out of 4 students experience high levels of stress, or a mental health condition, during their time at college. The survey, conducted by over a thousand students, also found that 70% of those that experience stress do so at least once a week, and 9% of them feel stressed constantly.
Kristy, a student at Exeter University, didn’t enjoy her first days in college. She says: “When I first got to university I don’t think I’d realized that I’d forgotten how to make friends. I’d been with the same school friends for seven years, and so I was trying to balance social success with academic success while learning how to look after myself at quite at a young age."
Dr. Ruth Caleb of the counseling service at Brunei University in London has some tips that should make life easier for students before they set off for university. She says: “Certain things that I think it would be very helpful for students to have put in place are an ability to do the practical things of life — to do the washing, to do the cleaning and so on— being able to cook. Budgeting(预算) is extremely important in university life.” And Caleb adds: “You should learn how to spend time on your own comfortably.”
I graduated and learnt how to take care of myself the hard way. I hope that new students these days remember to acquire some life skills before they make the big jump.
1.How does the writer feel about his university life?
A. Challenging but wonderful.
B. Busy and tiring.
C. Dull and stressful.
D. Boring but successful.
2.Which is true about students who first enter university?
A. Most of them suffer from frequent stress.
B. Most of them find it hard to manage their life.
C. They fail to balance social and academic life.
D. They feel as comfortable as they expect.
3.Dr. Ruth Caleb thinks budgeting is of great importance because it_________.
A. helps students put everything in place
B. helps students live independently
C. makes students' university life easier
D. does good to students’ social relationships
4.Which is closest in meaning to the underlined part in the last paragraph?
A. Become very successful.
B. Make great progress.
C. Get used to university life
D. Go to university.

A study showed that fat was socially catching among friends. People were actually making one another gain and, sometimes, lose weight. The finding has been proved in other populations. So how does friends’ body weight affect each other? One way is imitation (模仿). Brain scans show that when you watch someone else eat or run, your brain activity is the same as if you were eating or running yourself, causing you to do the same things.
People in experiments seated next to heavy eaters would eat more than those seated next to light eaters. Social examples also play a role: If your friend gains weight, you might become less willing to go to the gym because your friend’s example showed you that weight gain isn’t the end of the world. She’s heavier but still the same person you know and love. And now that 66 percent of the American population is overweight, that’s a pretty well-fixed social example.
Happily, this effect could be turned up side down if people worked to create an opposite social example—weight loss can affect each other just as easily as weight gain if you form the fat-fighting habits, starting a running club including friends of friends so that you’re making close friends with more exercisers. You can also make healthier food choices and eat with greater self-control. If you give up the fries and eat more vegetables, your friends are more likely to make the same choices.
If you’re thinking those sound like a lot of work, maybe it would just be easier to ditch friends who gain weight to stop them from affecting you. People who kept away from a fat friend didn’t lose weight, possibly because the cost of losing a friend stopped weight-loss efforts.
1.What will people in the experiments do if they eat with heavy eaters?
A. Hate them. B. Leave them.
C. Follow them. D. Lose weight.
2.How might people respond to their fat friends according to the text?
A. Go to the gym with them often.
B. Think nothing of becoming fat.
C. Warn them the danger.
D. Like them better.
3.What can you do to make good use of the discovery?
A. Set a good example for your friends.
B. Make up your mind to make more friends.
C. Set up health club as a business.
D. Drink more water.
4.What does the underlined word “ditch” in the last paragraph mean?
A. Depend on. B. Relieve in.
C. Watch over. D. Give up.

You may not know a lot of people when you start high school. Maybe your friends from middle school are going to a different high school. Even if you know other freshmen (新生), you still feel nervous that you don’t know any upper-classmen. How are you going to make friends among this sea of unknown faces?
Most high schools hold a freshman orientation (训练) before school actually starts. These are helpful not only because you learn your way around the building and get to meet some of your teachers, but you also get to meet fellow freshmen. That way, when you show up on your first day of school, you may already recognize a few familiar faces.
When you talk to people at orientation, you’ll probably find that a lot of them are feeling just like you are. They’re all new to the school and don’t know what to expect. Talking about a common concern with your classmates can help you develop friendships.
The work in high school is something freshmen are probably worried about. The work in high school builds on what you learned in middle school, giving you a more advanced knowledge of many subjects. So you may find you have more work to do or that it’s a bit more challenging. If you ever find your work too difficult, teachers can give you extra help.
High school also has more after-school activities than middle school did, such as clubs, music and theater groups and sports teams. This is a good time to explore your interests and try new things.
Middle school taught you the basics of academics, time management, and social skills while providing you with a little extra support and guidance. High school gives you the chance to learn how to be more independent and responsible.
1.According to the passage, when they come to the school on the first day freshmen usually feel ____.
A.proud B.nervous
C.excited D.afraid
2.What are freshmen probably worried about?
A.The learning task. B.The ability to make friends.
C.The training in the freshman orientation. D.The relationship with teachers.
3.After-school activities mainly help students ____.
A.build up healthy bodies B.develop friendships
C.develop their interests D.improve their learning ability
4.The last paragraph is mainly about ____.
A.what you’ll learn in high school
B.what you leaned in middle school
C.the difference between middle school and high school
D.the importance of being more independent and responsible
