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 socialising and meeting with friends help increase levels of brown fat in the body which burns calories(卡路里)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 socialising, 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.,,
【小题1】What information can we get from the first two paragraphs?

A.Brown fat stores calories and makes us fatter.
B.It doesn't take long to turn white fat into brown.
C.Social excitement helps gain more weight.
D.Brown fat can burn energy to produce heat.

A.Levels of brown fat can be increased by socialising.
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.
【小题3】We can conclude from the text that _______.
A.the fat in mice's belly was reduced because of the relaxing environment
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
D.cancer and death are mainly caused for lack of social life
【小题4】What’s the main idea of the text?
A.Brown fat is beneficial to people's health.
B.Socialising is unnecessarily important in people's daily life.
C.White fat can be changed into brown fat.
D.Socialising contributes to people's losing weight.

Every American family has its own traditions on Thanksgiving Day, and mine is no different. Once the national holiday arrives, my mom rises early to make the meal. She puts a turkey in the oven, chops carrots and bakes pies. I’m sorry to say that the men in the family – my dad, my younger brother and myself – rarely pitch in to help. Our job is to wash the mountain of dirty dishes after the meal is over.
Around 2 pm every Thanksgiving Day, family members seat themselves around the kitchen table. Plates of turkey, vegetables, salad, rolls and pies cover it. At this point, we can hardly keep ourselves from drooling (流口水) all over our fancy clothes, but it’s not yet time to eat.
First, we must bow our heads, close our eyes and say a prayer of thanks aloud to God for giving us everything we have. Under normal circumstances, I would have no problem making a list of things I am thankful for. I grew up in a loving family. My parents, who aren’t wealthy, took out loans to help me pay for university.
But, the funny thing is, every time I sit down for Thanksgiving dinner and try to say a prayer of thanks, my mind usually goes blank. I think it has something to do with my growling (咕咕叫) stomach and all of that food sitting right there under my nose.
Eventually, though, we all finish our short prayers and dig in. To be sure, the day includes other highlights – visiting with family and watching football. But usually around 6 pm we are all ourselves stuffed like turkeys and thankful to have a nice warm bed to sleep in.
【小题1】The purpose of the text is to ________.

A.tell what the family do for Thanksgiving Day
B.tell how the family spends Thanksgiving Day
C.introduce foods served on Thanksgiving Day
D.introduce the American Thanksgiving Day
【小题2】On Thanksgiving Day the author’s family do the following except ________.
A.watching a movieB.making visits
C.having a big mealD.watching football
【小题3】Why does the author’s mind usually “go blank” when saying a prayer of thanks?
A.He is too thankful to say a word.
B.His mind is on the food before him.
C.He feels too excited to speak.
D.He is shy to speak in public.
【小题4】The underlined phrase “dig in” in the last paragraph is closest in meaning to “________”.
A.chat with othersB.make a hole
C.mix things upD.start eating
【小题5】What can we conclude from the text?
A.On Thanksgiving Day, men do nothing but eat.
B.The author is a middle school student.
C.The author’s family is not rich, but it’s a loving one.
D.Thanksgiving Day falls on Thursday of December.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。
A
When I was sixteen years old, I made my first visit to the United States. It wasn’t the first time I had been abroad. Like most English children, I learned French at school. I had often been to France, so I was used to speaking a foreign language to people who didn’t understand French. But when I went to America, I was really looking forward to having a nice and easy holiday without any language problems.
How wrong I was! The misunderstandings began at the airport. I was looking for a public telephone to give my American friend Daisy a call and tell her that I had arrived. A friendly old man saw me looking lost and asked if he could help me.
"Yes, "I said, "I want to give my friend a ring. "
"Well, that's nice, "he said. "Are you getting married? But aren't you a bit young?"
"Who is talking about marriage?" I replied. "I only want to give my friend a ring to tell her I've arrived. Can you tell me where there's a phone box?"
"Oh! "he said. "There's a phone downstairs. "
When at last we met, Daisy explained the misunderstanding to me.
"Don't worry, "she said to me. "I had so many difficulties at first. There are lots of words which the Americans use differently in meaning from the British. You' ll soon get used to all the funny things they say. Most of the time, British and American people understand each other!"
56. The writer thought ______ in America.
A. he wouldn't have any language difficulties

What is EQ? In the early 1990s, Dr. John Mayer, Ph.D., and Dr. Peter Salovey, Ph.D., introduced the term “emotional intelligence” in the Journal of Personality Assessment. They used this term to describe a person’s ability to understand his or her own emotions and the emotions of others and to act properly based on this understanding. Then in 1995, psychologist Daniel Goleman popularized this term with his book Emotional Intelligence: Why It Can Matter More Than IQ.
EQ gives you a competitive advantage. Even at Bell Labs, where everyone is smart, studies find that the most respected and productive engineers are those with the special qualities of emotional intelligence quotient — it’s not necessary for them to have the highest IQ. Having a high IQ may make you an excellent expert or a legal scholar, but a highly developed emotional intelligence quotient will make you a candidate (候选人)for a leader or a brilliant lawyer. EQ can make it more likely that your marriage will be successful. Lack of EQ shows why people with high IQ can be such bad pilots of their personal lives.
The study shows that these men with high IQ also lack these emotional abilities: suffering from being criticized and misunderstood, shy and uncomfortable, emotionally stimulated(激励). Compared with those men with high IQ, these men (with high EQ) are calm and friendly, who are loyal to people and careers, have lots of sympathy with and care for others, with a rich but suitable emotional life  — they’re comfortable with themselves, others, and the human society they live in.
Is your intelligence the greatest predictor of what you’ll achieve in life? We have believed that IQ is the best measure of human potential for so many years. In the past 10 years, however, researchers have found that isn’t necessarily the case---that in fact, your EQ might be a greater predictor of success.
High IQ may help you the father of science fiction, but it won’t make you a respected person. High EQ can help you more.
【小题1】What can we learn from the second paragraph?
A In daily life and work, EQ is more important than IQ.
B High IQ will have a bad effect on people’s lives.
C It’s not necessary for people to have a high IQ.
D You’d better develop your intelligence well in order to be a leader.
【小题2】The underlined sentence “this isn’t necessarily the case” in Paragraph 4 means here that ____.
A your IQ is a greater predictor of success
B success is dependent on your IQ
C your EQ can predict your success better
D human potential is up to your IQ
【小题3】From the text, it can be inferred that ____
A high IQ can help you work better and succeed more easily
B high EQ must make you succeed
C all the bosses have a higher EQ than their employees
D those with high IQ are hot valued
【小题4】The text is written mainly to advise ____.
A people should only pay attention to their EQ
B people should develop their EQ as well as their IQ
C those who want to act as leaders should develop their EQ
D people should not develop their IQ too much
