Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.According to the passage, people are advised to take more Vitamin D, because__.

To win an Oscar is an achievement at any age. To do so at 22, as Jennifer Lawrence has, is just amazing. Recently, the American star won Best Actress at this year's Academy Awards for her role in the film The Silver Linings Playbook. According to Time magazine's Richard Corliss, Lawrence is that rare young actress who "lends a mature intelligence to any role".
Though Lawrence has found great success through her big screen work, Lawrence wasn't sure what she really liked doing before the age of 14. She thought she'd go to college and maybe find a career as a doctor or a travel agent.
Lawrence's two brothers were star athletes and one of them was a straight-A student. Unlike them, she suffered through school, never quite finding where she belonged. However, during a trip to New York, Lawrence suddenly realized that she wanted to be an actress. When she was enjoying the beautiful city, a model seeker asked if he could take her picture, and the next day he called her in for an audition (试镜).
"I read the script and it was the first time I had that feeling like I understand this," Lawrence said. "Within 20 minutes, in the cab ride from the hotel room, I decided I didn't want to be a model. In fact, I wanted to be an actress." Having appreciated this young lady's performance, the agency was so impressed with her reading that they signed her on the spot. But she insisted on finishing high school so she could give her full attention to her acting career.
Lawrence burst onto the Hollywood scene last year with The Hunger Games, which established her as the highest-grossing (票房最高的) female action hero of all time. Rolling Stone called her “the most talented young actress in America". What can we know about Jennifer Lawrence from Paragraph 3?
| A．Her parents were really strict with her. |
| B．She seemed not to fit in with her school days well. |
| C．Her school performance made her today's fame. |
| D．Her two brothers were doing well in all school subjects. |
Lawrence made up her mind to be an actress because of ______.
| A．a model interview |
| B．her brothers' examples |
| C．the taxi-ride to her hotel room |
| D．the beautiful scenery of New York |
From the text we can know that Lawrence is an actress of great ______.
| A．confidence | B．ambition | C．independence | D．talent |
What is the best title of the text?
| A．Choosing Right | B．Acting Wisely |
| C．Winning Young | D．Following Dreams |
Now came great news! It came from a neighboring state, where the family’s only surviving relative lived. It was Sally’s relative—a distant relative by the name of Tilbury Foster, seventy and single. Tilbury now wrote to Sally, saying he should shortly die, and should leave him thirty thousand dollars, cash; not for love, but because money had given him most of his troubles, and he wished to place it where there was good hope that it would continue its evil work. The bequest would be found in his will, and would be officially handed over provided that Sally should be able to prove to the executors (遗嘱执行人).
As soon as Aleck had partially recovered from the strong emotions created by the letter, she sent someone to the relative’s home and subscribed for the local paper.
For the rest of the day Sally made confusion with his books, and Aleck could not keep her mind on her affairs, not even take up a flower-pot or book or a stick of wood without forgetting what she had intended to do with it. For both were dreaming.
“Thirty thousand dollars!”
All day long Aleck was absorbed in planning how to invest it, Sally in planning how to spend it.
There was no romance-reading that night. The children took themselves away early, for their parents were silent, disturbed, and strangely unentertaining. Two pencils had been busy during that hour —note-making; in the way of plans. It was Sally who broke the stillness at last. He said, with excitement, “Ah, it’ll be grand, Aleck! Out of the first thousand we’ll have a horse and a buggy for summer, and a cutter and a skin lap-robe for winter.”
Aleck responded with decision and calmness.
“You can spend a part of it. But the whole of the capital must be put right to work.
“Why, yes. Yes, of course. Have you got it invested yet?”
“No, there’s no hurry about that; I must look around first, and think, er…, I’ve turned it over twice; once in oil and once in wheat.”
“Why, Aleck, it’s splendid! What does it amount to?”
“I think — well, to be on the safe side, about a hundred and eighty thousand clear, though it will probably be more.”
“My! Isn’t it wonderful? Good heaven! Luck has come our way at last, Aleck!”
Then they went up to bed, but they left the candle burning in the sitting room. They did not remember until they were undressed; then Sally was for letting it burn; he said they could afford it, if it was a thousand. But Aleck went down and put it out.
A good job, too; for on her way back she hit on a scheme that would turn the hundred and eighty thousand into half a million before it had had time to get cold. Why would Tilbury like to give all his money to Sally?
| A．Because Sally was Tilbury’s only relative alive. |
| B．Because Tilbury loved Sally and his family deeply. |
| C．Because Tilbury wanted his money to continue its function. |
| D．Because Sally and his wife are good at investing. |
The underlined word “bequest” in Paragraph1 probably means _________.
| A．a gift of personal property | B．a proof of a person’s identity |
| C．a method of getting money | D．a reason for giving money |
What do we know about Sally and his wife after receiving the letter?
| A．They were in deep sorrow and stayed up all night. |
| B．They cared little about the bequest and lived their life as usual. |
| C．They paid a visit to Tilbury to confirm the truth of the letter. |
| D．They had a big ambition to invest the money and make huge profits. |
Which of the following is the best title for the passage?
| A．Thrilling News | B．Sally’s Distant Relative |
| C．The $30,000 Bequest | D．A Smart Investment |

Why 2012 was the best year ever
It may not feel like it, but 2012 has been the greatest year in the history of the world. Never has there been less hunger, less disease or more prosperity (繁荣). The West remains in the economic depression, but most developing countries are charging ahead, and people are being lifted out of poverty at the fastest rate ever recorded. The number of deaths caused by war and natural disasters is also mercifully low. We are living in a golden age.
Take global poverty as an example. In 1990, the UN announced Millennium Development Goals, the first of which was to halve the number of people in extreme poverty by 2015. It turned out this year that the target was met in 2008.
The doom-mongers (末世论者) will tell you that we cannot maintain worldwide economic growth without ruining our environment. But while the rich world’s economies grew by 6 per cent over the last seven years, fossil fuel (矿物燃料) consumption in those countries fell by 4 per cent. This remarkable achievement has nothing to do with green taxes or wind-farms. It is down to consumer demand for more efficient cars.
Advances in medicine and technology mean that people across the world are living longer. The average life span in Africa reached 55 this year. Ten years ago, it was 50. The number of people dying from Aids has been in decline for the last eight years. Deaths from malaria have fallen by a fifth in half a decade.
War has historically been human’s biggest killer. But in most of the world today, a generation is growing up that knows little of it. The Peace Research Institute in Oslo says there have been fewer war deaths in the last decade than any time in the last century.
Fifty years ago, the world was breathing a sigh of relief after the Cuban missile crisis. Young couples would discuss whether it was responsible to have children when the future seemed so dark. But now, it’s worth remembering that, in spite of all our problems, the forces of peace, progress and prosperity are prevailing (占优势).What has caused the decrease in the fossil fuel consumption?
| A．People have to pay heavier taxes on fossil fuel. |
| B．There are more and more renewable resources now. |
| C．There is a sharp decline in the number of cars. |
| D．People are purchasing more energy-saving cars. |
Which of the following statements is TRUE?
| A．People don’t suffer from malaria any more. |
| B．There were many more war deaths in the last century. |
| C．The young generation shows little interest in war. |
| D．The number of Aids-affected people is declining. |
Which one does NOT help prove that 2012 was the best year ever?
| A．Fewer natural disasters occurred. | B．Global poverty relieved. |
| C．Cuban missile crisis ended. | D．Technology and medicine advanced. |
The author tries to inform people that _______.
| A．2012 witnessed more advances in developed countries |
| B．2012 brought us less starvation and more prosperity |
| C．2012 saw economic growth as well as environmental destruction |
| D．2012 provided us with a peaceful world free from conflicts |
The argument over a Philadelphia school district accused of secretly spying on pupils through laptop cameras became fiercer today after it acknowledged obtaining more than 56,000 images of its students, many of them in their homes.
When the scandal (丑闻) first broke, it was believed that only a few pictures had been taken of one pupil, Blake Robbins. But court papers released this week showed that thousands of images were taken of Robbins and other students.
Robbins and his parents have filed an action against the school district. Court papers from the Robbins’s lawyers said that at first it was thought that the laptops’ technology had produced a few images but they found more than 400 of Robbins, including images “showing him partially undressed and sleeping”.
Robbins said he did not know why the spying device was activated (激活) as his laptop had not been reported stolen or missing. Other students whose pictures were taken said their laptops had not been reported stolen or missing either.
An administrator at the school, one of the few with authority to track the laptops, remained silent, refusing to answer questions.
The Philadelphia Inquirer reported that 38,500 of the images came from six laptops that had been reported missing from the Harriton gym in September 2008. These apparently helped the police catch a suspect. Another set of images were from cameras in laptops which employees responsible for tracking failed or forgot to turn off.
The court papers, filed by Robbins’ lawyers, said that the technology was activated between 20 October and 4 November last year, with most of the 400 shots of him while he was in his home, and included his family. “There were additional webcam pictures and screen shots taken of Blake Robbins which, up to now, have not been recovered because the evidence was deleted by the IT department,” the court papers say.
One of Robbins’ lawyers is trying to obtain access to the administrator’s home computer to confirm whether she downloaded any of the pictures. The court papers indicate she may be a voyeur (窥隐私者) though it has not been proved. We can learn from the passage that _________.
| A．Robbins’ parents remained calm over the scandal |
| B．Robbins had his laptop stolen before the scandal |
| C．the laptops’ technology produced some images |
| D．the private rights of the students were offended |
What did The Philadelphia Inquirer say about the case?
| A．The police had found some evidence. |
| B．Most of the laptops in Harriton gym were missing. |
| C．Employees in charge of tracking deliberately left the laptops on. |
| D．There was obviously more than one suspect related to the case. |
According to the court papers, the administrator _________.
| A．may have spied her students on purpose |
| B．may have broken into Robbin’s house |
| C．has downloaded many students’ pictures |
| D．has removed evidence from computers |
What does the passage mainly talk about?
| A．Modern technology has negative effects on our lives. |
| B．Students in Philadelphia are accustomed to being spied on secretly. |
| C．A Philadelphia school is charged with spying students through laptop cameras. |
| D．The American government should take measures to improve teachers’ qualities. |
