19.A study,by San Diego Zoo Global conservationists,released this week (Sept.12,2016)is shedding new light on how scientists evaluate polar bear diet and weight loss during their fasting(禁食) season.On average,a polar bear loses up to 30percent of its total body mass(体重)while fasting during the open-water season.Although some scientists previously believed land-based foods could supplement(补充)the bears'nutritional needs until the sea ice returns,a new study published in the scientific journal Physiological and Biochemical Zoology has revealed that access to terrestrial food is not sufficient to reduce the rate of body mass loss for fasting polar bears.
The study--undertaken by Manitoba Sustainable Development,the University of Alberta,and Environment and Climate Change Canada--weighed polar bears that were detained in the Polar Bear Holding Facility in Churchill,Manitoba,Canada from 2009 to 2014.Polar bears were kept in this facility as part of the Polar Bear Alert Program,which aims to reduce conflict between humans and polar bears around the town of Churchill.To prevent habituation,polar bears are not fed while in the facility,which allowed for a controlled measure of their weight loss.On average,polar bears lost 2.2 pounds(1 kilogram)of mass per day--exactly the same amount as free-ranging(自由放养的)bears measured during the ice-free season on the coastline of Hudson Bay.Scientists reported that even with land-based food opportunities,polar bears lost the same amount of weight.
"Some studies have suggested that polar bears could adapt to land-based foods to offset the missing calories during a shortened hunting period on the ice,"said Nicholas Pilfold,Ph.D.,lead author of the study and a postdoctoral associate in Applied Animal Ecology at San Diego Zoo Global."Yet,our results contradict this,as unfed polar bears in our study lost mass at the same rate as free-ranging bears that had access to land-based food."
Researchers also estimated starvation timelines for adult males and subadults,and found that subadults were more likely to starve before their adult counterparts."Subadult polar bears have lower fat stores,and the added energy demands associated with growth,"said Pilfold,"Future reductions to on-ice hunting opportunities due to sea ice loss will affect the younger polar bears first--especially given that these bears are less-experienced hunters."

63.What is the finding of this newly-released study?B
A.Wild polar bears are facing the danger of starvation and extinction.
B.Land-based food can't meet the nutritional needs of wild polar ears.
C.Wild polar bears can avoid weight loss in a properly designed facility.
D.Traditional ways to measure polar bear diet and weight loss are not accurate.
64.Which of the following is TRUE about the study?C
A.It was actually part of the Polar Bear Alert Program.
B.It aimed to prevent the polar wildlife from extinction.
C.It compared the weight loss between unfed and free-ranging polar bears.
D.lt measured the weight of polar bears during on-ice hunting seasons.
65.The underlined word in the fourth paragraph meansD.
A.take over
B.take up
C.make into
D.make up for
66.The reasons why subadults are more likely to suffer during open-water season includeA.
They have less fat storage.
They need more energy for growth.
They lack hunting opportunities.
They are slower in adapting to ice loss.

科目:gzyy 来源: 题型:

 Researchers have just offered evidence in a study that says obesity (肥胖)

appears to spread through social ties,much like a virus. When one person gains  

weight,their close friends often follow. But the findings might also offer   

hope.   

 If friends help make obesity acceptablethen they might also be influential in losing the fat. The researchers note that support groups are already an effective tool in dealing with other socially influenced problems,like alcoholism.

The findings appeared in the New England J ournaI of Medicine. The  researchers used information collected from 12,000 people. It was collected between 1971 and 2003  as part of the Framingham Heart Study.  

 The information was highly detailed. There was even contact information for close friends of the people in the study.

The researchers examined more than 40,000 social ties. They found that a person’s chances of becoming severely overweight increased by 57 % if a friend had become obese.

 A sister or brother of a person who became obese had a 40 % increased chance of becoming obese. The risk for a wife or husband was a little less than that.

Nicholas Christakis of Harvard Medical School was a lead investigator in the study. He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend.

The study found that the sex of the friends was also an influence. In same-sex friendships,a person had a 71% increased risk of becoming obese. Men had a 44 % increased risk of becoming obese after weight gain in a brother. In sisters,it was 67%.

The researchers also considered the effect of where people lived in relation to each other. James Fowler of the University of California,San Diego,was the other lead investigator. He says a friend who lives a few hundred kilometres away has as much influence as one in the same neighbourhood. He says the study demonstrates the need to consider that a major part of people’s health is tied to their social connections.

Both investigators say their research shows that obesity is not just a pri

vate medical issue,but a public health problem.

1. What does the underlined sentence in Paragraph 2 mean?

   A. Obesity has a negative influence on a close friend.

   B.  Friends might also play a part in losing weight.

   C.  One might have a positive influence on one’s friend.

   D.  Friends usually don’t follow each other to lose weight.

2. Who is most likely to gain weight?

   A. A man who has a fat brother.

   B.  A husband who has a fat wife.

   C.  A wife who has a fat husband.

   D.  A woman who has a fat female friend.

3. Which of the following statements does the passage disagree with?

   A. You are sure to lose weight if you have a skinny friend.

   B.  If one gains weight,one’s friends are likely to get fat.

   C.  A person’s health is closely linked with his/her social relationship.

   D.  Even if a friend lives far away,the influence still remains.

4. The reason why the study involves both family members and friends is that

   A. researchers fail to find a more different sample

   B.  researchers have different ideas for family members and friends

   C.  researchers can meet these people regularly

   D.  researchers can compare the results

阅读理解

  A study conducted by the Infant (婴儿) Testing Center in San Francisco, California, suggests that babies feel more comfortable around other babies than with strange adults. According to the study, babies benefit by being with their fellow infants daily. As a baby might show fear of an adult stranger, he is likely to smile and reach out for an unfamiliar infant. By the time babies are one year old, they have begun to form friendships of sorts.

  The above findings, based on observation of 100 babies aged three months to three years, might prove interesting to working parents who must find day care for their babies. Family care in a private (私人的) home, with several babies together, is probably a very good way to care for babies under three.

  Benjamin Spock, well-known doctor and author of books about babies, support the idea. He says that family day care is better in theory than hiring a housekeeper or a babysitter.

(1) What would be a good title for the passage?

[  ]

A.How to Test Infants
B.Parents and Children
C.Daily Care for Babies
D.Choosing a Babysitter

(2) A baby is likely to feel more at ease with ________.

[  ]

A.a housekeeper
B.an infant
C.an adult stranger
D.a student

(3) What does Dr. Benjamin Spock do?

[  ]

A.He trains babysitters.

B.He writes baby books.

Researchers have just offered evidence in a study that says obesity appears to spread through social ties, much like a virus. When one person gains weight, their close friends often follow, but the finding might also offer hope.

If friends help make obesity acceptable, then might also be influential in losing the fat. The researchers note that support groups are already an effective tool in dealing with other socially influenced problems, like alcoholism. 

The findings appeared in the New England Journal of Medicine, The researchers used information collected from 12,000 people. It was collected between 1971 and 2003 as part of the Framingham Heart Study.

The information was highly detailed. There was   even contact information for close friends of the people in the study.  

The researchers examined more than 40,000 social ties. They found that a person’s chances of becoming severely overweight increased by 57% if a   friend had become obese.

Nicholas Christakis of Harvard Medical School was a lead investigator in the study. He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend. 

The study found that the sex of the friends was also an influence. In same-sex friendships, a person had a 70% increased risk of becoming obese. Men had a 44% increased risk of becoming obese after weight gain in brothers. In sisters, it was 67%. Between husbands and wives, it was a little less than 40%. 

The researchers also considered the effect of where people lived in relation to each other. James Fowler of the University of California, San Diego, was the other lead investigator. He says a friend who lives a few hundred kilometers away has as much influence as one in the same neighborhood. He says the study demonstrates the need to consider that a major part of people’s health is tied to their social connections.

Both investigators say their research shows that obesity is not just a private medical issue, but a public health problem.

A. Obesity has a negative influence on a close friend.

The World Health Organization recently reported that the number of cases of tuberculosis(TB) has been abating since 2006 . Also, fewer people are dying from TB. But a study by researchers at the University of California, San Francisco, says smoking could threaten this progress.
Nearly twenty percent of all people use tobacco, and millions of non-smokers get sick from breathing the smoke. The new study predicts that smoking will produce an additional thirty-four million TB deaths by 2024.
Efforts to control the spread of TB have mainly focused on finding and treating infections. Fewer efforts have been made to understand the causes. Dr Anthony Fauci is the director of the United States National Institute of Allergy and Infectious diseases. He said, “Despite our control efforts, we still have more than a million people each year dying from TB and millions of people  getting infected; we realize it’s still a very important problem. So we have to do the practical thing and we have to do the fundamental research things at the same time. ”
Smoking does not cause TB; bacteria cause the infection. But the study says smoking affects the nervous system in a way that makes an inactive case of TB more likely to develop into an active one. Stanton Glantz is the director of the University of California’s Centre for Tobacco Control Research and Education and an author of the new study. He says it shows that TB cannot be controlled unless tobacco use is controlled.  He said, “It increases the number of people who will get TB by about seven percent.”
The study is described as the first to identify a direct link between tobacco use and rates of TB infection and death. Professor Glantz says the results should guide those creating health policies and TB control efforts. He said, “If you want to control the infectious disease of TB, you have to control the tobacco industry and the tobacco industry’s efforts to increase tobacco use, particularly in developing countries where TB is a big problem.”
【小题1】What would be the beat title for this passage?

A.Scientists try to find the causes of TB deaths.
B.Study shows smoking is harmful to our health.
C.Study links smoking to millions of TB deaths.
D.Scientists pay more attention to TB deaths than before.
【小题2】What does the underlined word “abating” in Paragraph 1 mean?
A.RespondingB.Surviving.C.Rising.D.Falling.
【小题3】 What would Dr Anthony Fauci probably agree with?
A.More efforts are needed to find the causes of TB infections.
B.TB infections are no longer a serious problem.
C.Few efforts have been put into the work of treating TB infections.
D.The practical and the fundamental research cannot be done together at present.
【小题4】It is implied in the passage that ____________.
A.it is not very hard to control TB
B.smoking indirectly leads to TB
C.an inactive case of TB is deadly
D.people cannot blame smoking for TB

A sister or brother of a person who became obese had a 40% increased chance of becoming obese. The risk for a wife or husband was a little less than that.
Nicholas Christakis of Harvard Medical School was a lead investigator in the study. He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend.
The study found that the sex of the friends was also an influence. In same—sex friendships, a person had a 71% increased risk of becoming obese. Men had a 44% increased risk of becoming obese after weight gain in a brother. In sisters, it was 67%.
The researchers also considered the effect of where people lived in  relation to each other. James Fowler of the University of California,San Diego, was the other lead investigator. He says a friend who lives a few hundred kilometers away has as much influence as one in the same neighborhood. He says the study demonstrates the need to consider that a major part of people’s health is tied to their social connections.
Both investigators say their research shows that obesity is not just a private medical issue, but a public health problem.
59.What does the underlined sentence in Para. 2 mean?
A.Obesity has a negative influence on a close friend.
B.Friends might also play a part in losing weight.

E
Researchers have just offered evidence in a study that says obesity appears to spread through social ties, much like a virus. When one person gains weight, their close friends often follow, but the finding might also offer hope.
If friends help make obesity acceptable, then might also be influential in losing the fat. The researchers note that support groups are already an effective tool in dealing with other socially influenced problems, like alcoholism.
The findings appeared in the New England Journal of Medicine, The researchers used information collected from 12,000 people. It was collected between 1971 and 2003 as part of the Framingham Heart Study.

17.When University of California-Berkeley released a study this month showing alarmingly high teacher turnover (人员流动) rates at Los Angeles charter (特许) schools,I wasn‘t surprised.
That's not shocking news at local charter schools.It‘s just that the study reminded me of something I'd observed many times,starting with my niece.
Bright and cheerful,my niece longed to teach high-needs children.She started out in the San Francisco public schools,where she was assigned to the district‘s toughest elementary school.Fifth-graders threw chairs across the room-and at her.Parents refused to show up for conferences.
She wasn't willing to deal with this level of indifference and teacher abuse,so she switched to a highly regarded charter elementary school in the Bay Area where she poured her energy into her job and it showed.Her students‘test scores were as high as those in a nearby wealthy school district,despite the obstacles these children faced.
By her fourth year,however,my niece was worn out,running out of the energy it took to work with a classroom of sweet but deeply needy children who begged to stay in her classroom when it was time to leave.The principal‘s offer of a $10,000raise couldn‘t stop her from giving notice.She went to work at that wealthy school district next door-for less money.
Over the years,I've met many teachers who have a passion for their work at charter schools,only to call them the next year and find they‘ve left.The authors of the Berkeley study hold the belief that the teachers leave because of the extraordinary demands:long hours,intense involvement in students complicated lives,continual searches for new ways to raise scores.Even the strongest supporters of the reform movement acknowledge that raising achievement among disadvantaged students is the most challenging task.
It‘s unlikely that we can build large-scale school reform on a platform of continual new demands on teachers-more time,more energy,more devotion,more responsibility-even if schools find ways to pay them better.
This is the bigger challenge facing schools.We need a more useful answer to the Berkeley study than-Yeah,its really hard work.

50.Why wasn‘t the author surprised at the problem?C
A.She had been informed of the problem by her niece.
B.She had participated in the Berkeley study.
C.She had noticed the phenomenon repeatedly.
D.She had been warned of the problem by the media.
51.What can we learn about the students in the public school the author‘s niece taught?B
A.They were clever and cheerful.
B.They were not disciplined.
C.They were indifferent to each other.
D.They were forced to learn by their parents.
52.The author‘s niece left the charter elementary school in the Bay Area becauseC.
A.her hard work and devotion didn‘t pay off
B.her work was not well received by the children
C.the demanding work made her exhausted
D.the mean principle offered her a low salary
53.Which of the following is probably the most difficult for teachers?A
A.Raising disadvantaged students‘scores.
B.Frequent involvement in students‘lives.
C.Indifference from students‘parents.
D.Long working time and much energy.
54.What is the author's comment on the current school reform movement?B
A.It will have a positive impact on education.
B.It tends to be unsuccessful.
C.It will make teachers more motivated.
D.It demands more fund to meet the challenge.
