Eating a diet high in processed（加工） food increases the risk of depression（抑郁）, research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.
Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet--those who ate a diet largely based on whole food，which includes lots of fruit, vegetables and fish，and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat，refined（精制的） grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
Those who ate the most wholefood（全天然食物） had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods.
Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for.（解释原因） He also pointed in a paper that a Mediterranean(地中海) diet was associated（有关） with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood （可能）of you eating a Mediterranean diet is not very high.
Dr．Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
He added people's diets were becoming increasingly unhealthy. The UK population is consuming （消费）less nutritious, fresh produce and more saturated（饱和） fats and sugars.
The text is mainly about______.

A．the increasingly unhealthy diet of the UK population

B．the link between processed food and depression

C．the relationship between physical and mental health

D．the emotional state of the British People

What can we learn from what Dr. Archana Singh Manoux said?

A．It is difficult for most British people to have a Mediterranean diet.

B．The Mediterranean diet is the most healthy in the world.

C．Many studies have been done on the Mediterranean diet before.

D．The Mediterranean diet is not good for depression.

Dr. Andrew McCulloch agrees that______.

A．our diets are closely related to our mental health

B．the present study needs more facts and other information

C．the UK population will become ill in the near future

D．more saturated fats and sugars should be taken in

Why might the author have written this text?

A．To tell people what a healthy diet actually is.

B．To prove people’s diets are increasingly unhealthy.

C．To encourage people to cut down on processed food.

D．To introduce some experts on the research team.

City officials are hoping to use the power of dog droppings. San Franciscans already recycle more than 60% of their dogs’ droppings, but in this dog-friendly town, such wastes make up nearly 4% of residential waste, or 6,500 tons a year.
Within the next few months, Norcal Waste, a company that collects San Francisco’s wastes, will begin a trial program under which it uses biodegradable (生物分解的) bags and dog-waste carts to pick up droppings at a popular dog park.
The droppings will be thrown into a machine called a methane digester (沼气处理机), which is basically a tank in which bacteria feed on droppings for weeks to create methane gas.
The methane could then be piped directly to a gas stove, a steam heater, an air turbine or anything else powered by natural gas. It can also be used to produce electricity.
Someone doubts whether this plan is practical. But Norcal Waste spokesman, Robert Reed points to San Francisco’s creative food composting (混合肥料) program, which began 10 years ago. It is a proof that an unusual idea can work in this forward-thinking city. Norcal Waste collects 300 tons of food left over after meals per day from homes and restaurants and changes it into a rich fertilizer sold to grape farms and organic farms.
Methane digesters are nothing new. The technology was introduced in Europe about 20 years ago, and more than 600 farm-based digesters are in operation there. Nine are in use on California cow farms, and chicken and pig farms elsewhere in the United States also use them.
“The main obstacle is probably getting communities around the country the courage to collect dog droppings, to give value to something we’d rather not talk about,” Brinton, a recycling and composting consultant, said. “San Francisco is probably the king of pet cities. This could be an advantage of it, which is very important.”
Some other experts believe energy production from dog droppings must become more attractive economically before it gets popular. Landfill space is relatively cheap, and natural gas and electricity also remain fairly inexpensive. However, Reed said confidently, “Now, the city authorities asked us to look at dog waste specifically.”
61. How many dogs’ droppings can be recycled at present per year in San Francisco?
A. About 6,500 tons.                    B. About 169,000 tons.
C. About 260 tons.                          D. About 3,900 tons.
62. It can be inferred from the passage that        .
A. there are many pets that are treated well in San Francisco
B. Norcal Waste is a company of refuse (垃圾) treatment, which collects dog wastes only
C. most of the farms in Europe use Methane digesters
D. Brinton doesn’t feel optimistic about the collection of dog droppings in San Francisco
63. The underlined word “obstacle” in Paragraph 7 most probably means        .
A. interest         B. effect         C. difficulty       D. purpose
64. Which of the following is TRUE according to the passage?
A. San Francisco is a city full of innovation.
B. Dog droppings can be changed into methane gas in several days.
C. It is the first time to utilize animal waste in San Francisco.
D. Utilizing dog droppings presently is more economical than the landfill.
65. Which of the following can be the best title of this passage?
A. Animal wastes collection by Norcal Waste
B. Changing dog droppings into energy
C. Methane digester technology in San Francisco
D. A dog droppings composting program

China may send naval ships to the seas off Somalia to help the fight against piracy（海盗行为） there, Chinese media on Wednesday quoted a Vice Foreign Minister as saying at the United Nations, Reuters reported.
"China is seriously considering sending naval ships to the Gulf of Aden and waters off the Somali coast for escorting operations in the near future," the Xinhua news agency quoted He Yafei as saying. He Yafei, speaking at a Security Council ministerial meeting, said that China welcomed global cooperation in the fight against Somali piracy, and supported efforts by other countries to send ships to the region, Xinhua reported.
Earlier this month a leading Chinese military strategist, Major-General Jin Yinan, urged the government to send ships, in comments generating debate about combating piracy in a country which has generally confined its navy to waters near home. Jin told a Chinese radio interviewer that "nobody should be shocked" if his government one day decided to send navy ships to deal with the pirates, whose recent victims have included ships from Chinese mainland and Hong Kong. Jin is the head of a strategy institute at China's National Defense University.
While the military strategist is urging an active part, other scholars think the government should be cautious before a decision is made. The Chinese military ships should go there "only within the UN framework," said Pang Zhongying, a professor of international relations with Renmin University of China. Pang added that he also had some concerns over the Chinese navy's capability. "I don't think the Chinese navy has the capability to fight against unconventional threats far in the ocean," he said, adding supplying and refueling in the Indian Ocean are key challenges.
A sharp increase in attacks at sea this year in the busy Gulf of Aden and Indian Ocean off Somalia has pushed up insurance costs, brought the Somali pirates tens of millions of dollars in ransom（赎金） and prompted foreign warships to the area. Among the captured ships are a Saudi supertanker loaded with $100 million of crude oil, the Sirius Star, and a Ukrainian cargo ship carrying some 30 Soviet-era tanks. The victims have also included a Hong Kong-flagged ship with 25 crew aboard and a Chinese mainland fishing boat reported seized off Kenya. NATO ships began anti-piracy operations off the Somali coast in late October, but they have failed to stop the attacks.
56. This year, many ships from different countries have been captured by the Somali pirates except _______.
A. a Saudi supertanker B. a Ukrainian cargo C.NATO ships D. the Sirius Star
57. The underlined word "confined" in the third paragraph most probably means ________.
A. involved B. restricted C. confirmed D. contract
58. From the passage, we learn that _______.
A. China has sent its navy to fight the Somalia pirates
B. some countries have launched their anti-piracy operations
C. the Somalia pirates often attacked foreign warships for ransom
D. The Chinese navy hasn’t the capability to travel far to combat pirates
59. When the Major-General Jin Yinan said "nobody should be shocked", he actually indicated that ________.
A. the Chinese people should keep calm about the government's decision
B. no one should be frightened by the pirates' attack as the Chinese navy will defend them
C. it is reasonable for China to send its navy to fight against the Somalia pirates
D. if China had dealt with the pirates earlier, nobody would have been shocked
60. Professor Pang Zhongying’s main concern about the Chinese naval ships is that _______.
A. adding supplying and refueling far in the ocean is really a challenge
B. the Chinese navy has never fought against such unconventional threats
C. the fighting against pirates is not within the UN framework
D. the attacks in the Gulf of Aden and Indian Ocean off Somalia has increased sharply

Recently, a survey was done among 288,000 students, which shows that today’s traditional-age college freshmen are “more materialistic and less altruistic (利他主义的)” than at any time in the 19 years of the poll (民意调查).
Not surprisingly, in these hard times, the students’ major purpose “is to be financially well off. Developing a meaningful philosophy of life is less important than ever.” It follows then that today the most popular course is not literature or history but accounting.
Interest in teaching, social service and the “altruistic” fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up.
That’s no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors in her first year on the job---even before she completed her two-year associate degree.
Though it’s true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far beyond our own and that it will be better for our understanding of these other contributions—either scientific or artistic.
Similarly, it is true that, in studying the diverse wisdom of others, we learn how to think. More importantly, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs.
Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; No job. How shortsighted in the long run!
But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机) : “Miss Baxter,” he says, “could you please send in someone who can distinguish right from wrong?”
From the long-term point of view, that’s what education really ought to be about.
51. According to the result of the survey, college students _______________.
A. take developing a meaningful philosophy of life more seriously
B. have a wide range of knowledge in many aspects
C. pay more attention to the study of literature
D. have never been so materialistic as today
52. The students’ criteria (标准) for choosing their majors today are largely based on _________.
A. their own understanding of the courses
B. the financial goals they seek in life
C. the influence of their instructors
D. the vast potential for the future educational development
53. What does the fifth paragraph imply?
A. Knowledge in other fields has nothing to do with one’s career.
B. Business management should be included in educational programs
C. The importance of a broad education should not be ignored
D. A good understanding of the civilization will make students rich.
54. The author’s attitude to the effect of studying the diverse wisdom of others is ______________.
A. positive B. indifferent C. doubtful D. negative
55. The writer wrote the passage in order to indicate that ______________.
A. college students today are not a diligent generation
B. people engaged in technical jobs lead a more meaningful life
C. career seekers shouldn’t focus on immediate interests only
D. working experience outside college counts a lot to one’s future career

B
Kincaid looked at his watch: eight-seventeen. The truck started on the second try, and he backed out, shifted gears, and moved slowly down the alley under hazy sun. Through the streets of Bellingham he went, heading south on Washington 11, running along the coast of Puget Sound for a few miles, then following the highway as it swung east a little before meeting U.S Route 20.
Turning into the sun, he began the long, winding drive through the Cascades. He liked this country and felt unpressed stopping now and then to make notes about interesting possibilities for future expeditions or to shoot what he called “memory snapshots.” The purpose of these causal photographs was to remind him of places he might want to visit again and approach more seriously. In later afternoon he turned north at Spokane, picking up U.S Route 2, which would take him halfway across the northern United States to Duluth, Minnesota.
He wished for the thousandth time in his life that he had a dog, a golden retriever, maybe, for travels like this and to keep him company at home. But he was frequently away; overseas much of the time and it would not be fair to the animal. Still, he thought about it anyway. In a few years he would be getting too old for the hard fieldwork. “I must get a dog then.” He said to himself.
Drives like this always put him into a sentimental mood. The dog was part of it. Robert Kincaid was alone as it’s possible to be – an only child, parents both dead, distant relatives who had lost track of him and he of them, no close friends.
He thought about Marian. She had left him nine years ago after five years of marriage. He was fifty–two now, that would make her just under forty. Marian had dreams of becoming a musician, a folksinger. She knew all of the Weavers’ songs and sang them pretty well in the coffeehouse of Seattle. When he was home in the old days, he drove her to the shows and sat in the audience while she sang.
His long absences – two or three months sometimes – were hard on the marriage. He knew that. She was aware of what he did when they decided to get married, and both of them had a vague (not clear) sense that it could all be handled somehow. It couldn’t when he came from photographing a story in Iceland and, she was gone. The note read, “Robert, it didn’t work out, I left you the Harmony guitar. Stay in touch.”
He didn’t stay in touch. Neither did she. He signed the divorce papers when they arrived a year later and caught a plane for Australia the next day. She had asked for nothing except her freedom.
46. Which route is the right one taken by Kincaid?
A. Bellingham – Washington 11 – Puget Sound – U.S Route 20 – U.S Route 2 – Duluth
B. U.S. Route 2 – Bellingham – Washington 11 – Puget Sound – U.S Route 20 – Duluth
C. U.S. Route 2 – U.S Route 20 – Duluth – Bellingham – Washington 11
D. Bellingham – Washington 11 –U.S. Route 2 –U.S Route 20 –Duluth
47. Which statement is true according to the passage?
A. Kincaid’s parents were dead and he only kept in touch with some distant relatives.
B. Kincaid would have had a dog if he hadn’t been away from home too much.
C. Kincaid used to have a golden retriever.
D. Kincaid needed a dog in doing his hard fieldwork.
48. Why did Kincaid stop to take photos while driving?
A. To write “memory snapshots”.
B. To remind himself of places he might want to visit again.
C. To avoid forgetting the way back.
D. To shoot beautiful scenery along the road.
49. What can you know about Marian?
A. She died after five years of marriage.
B. She was older than Kincaid.
C. She could sing very well and earned big money.
D. She was not a professional pop singer.
50. We can draw a conclusion from the passage that _____
A. Marian knew what would happen before she married Kincaid.
B. Kincaid thought his absence would be a problem when he married Marian.
C. It turned out that Marian could not stand Kincaid’s absence and left him.
D. After Marian left him, they still kept in touch with each other.

　　阅读下面短文，从每题所给的A、B、C和D项中选出最佳选项，并在答题卡上将该项涂黑。
A
Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
41. According to the new findings, taking steps to prevent northern forest fires may __________.
A. result in a warming climate
B. cause the forest fires to occur more frequently
C. lead to a longer fire season
D. protect the forests and the environment there
42. The following are all the immediate effects after a forest fire EXCEPT __________.
A. large amounts of greenhouse gases enter the atmosphere
B. the levels of ozone which is a type of oxygen increase
C. snow on the ground mirrors more sunlight back into space
D. ashes from the fire fall on the ice surface and take in more radiation from the sun
43. Earlier studies about northern forest fires __________.
A. analyze all aspects of how northern fires influence climate
B. indicate that forest fires will pollute the atmosphere
C. suggest that people should take measures to protect environment
D. suggest that the fires will speed up climate warming
44.The underlined phrase “soak up” in the last paragraph most probably means __________.
A. released         B. absorbed       C. created      D. distributed
45. From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________.
A. warm the climate as the supposition goes
B. allow more snow to reflect more sunlight into space and thus cool the climate
C. destroy large areas of forests and pollute the far-off sea ice
D. help to gain more energy rather than release more energy
