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.

We often use the words “growth” and “development” as if they meant basically the same thing. But this may not always be the case. One can easily imagine instances in which a country has achieved higher levels of income (growth) with little or no benefit coming to most of its citizens (development).
In the past, most development policies were aimed at increasing the growth rate of income per capita (人均所得). Many are still based on the theory that benefit of economic growth will come to all members of society. If this theory is correct, growth should encourage development.
By the early 1970s, however, the relationship between growth and development was being questioned. A major study by the World Bank in 1974 concluded that it is now clear that more than decades of rapid growth in developing countries has been of little benefit to & third of their population.
The World Bank study showed that increase in GNP per capita did not promise important improvements in such development indicators as nutrition (营养), health, and education. Although GNP per capita did indeed rise, its benefit came down to only a small part of the population. This realization gives rise to a call for new development policies. These new policies favor agriculture over industry, call for national redistribution (资源分配) of income and wealth, and encourage programs to satisfy such basic needs as food and shelter.
In the late 1970s and early 1980s the international macroeconomic crises (大规模的经济危机) of high oil prices, worldwide recession (衰退) and the third world debt, forced attention away from programs designed to get rid of poverty. however, the lesson remains: economic growth does not promise economic development. Efforts may be required to change growing output capacity (能力) into economic benefit that reach most of a nation’s people. What do we learn from the first paragraph about the relationship between growth and development?
A.Growth and development refer to the same thing. |
B.Growth always brings about development. |
C.Development is not a necessary result of growth. |
D.Development is a reliable measure of growth. |
Before the 1970s, most development policies were based on theory that economic growth would benefit ________.
A.most people in society | B.some people in society |
C.few people in society | D.everyone in society |
according to the study by the World Bank in 1974, economic growth in some backward countries brought ________.
A. benefit to a third of their population
B. benefit to two thirds of their population
C little benefit to their people
D. no benefit at all to their peopleIf the passage continues, what would the author most likely discuss in the next paragraph?
A.How to turn growth into development. |
B.How to remove poverty from society. |
C.How to decrease the third world debt. |
D.How to cope with economic crises. |
Having one of those days or weeks — when everything seems to annoy you? Even if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster — often within a day or two.
Walk it off
Exercise is the most popular bad-mood buster. A person who’s in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing that bad mood.
Tune it out
Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we’ve had.
Give yourself a pep talk
Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper; the pessimistic (悲观的) messages you’ve been giving yourself and then give optimistic answers. ("I still don’t have a job. "vs" I have two interviews next week.")
Reduce your stress
Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing (想象), all of which sound complicated but aren’t. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to against distress is to make a to-do list. One reason for being in a bad mood is feeling you have no options(选择权) By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.
Avoid things that won’t improve your mood
TV may not help much: You need to increase your energy level and stimulate your mind something — that the TV show "Neighbors" won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta, produce a calming effect in people who have a desire for them. We learn from the text that it might help rid us of a bad mood ________.
A.to do nothing about it |
B.to take a long walk on the beach |
C.to do some exercises with light music |
D.to talk it to neighbours |
Why is it suggested that you close your eyes and picture the beach?
A.It is not complicated to do so. |
B.It is an area to be easily controlled. |
C.It helps beat a bad mood. |
D.It brings us a new technique. |
TV may not improve your mood because ________.
A.it sometimes shows what happens around you |
B.it keeps you stay unmoved |
C.it reminds you of eating and drinking |
D.it produces a calming effect |
This text most probably appears in ________.
A.a book on physical exercises | B.a doctor’s handbook |
C.a notice | D.a magazine |
In ancient times the most important examinations were spoken, not written. In the schools of ancient Greece and Rome, testing usually was made up of saying poetry aloud and giving speeches.
In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss questions in their field of study with people who had made a special study of the subject. This custom exists today as part of the process of testing candidates (应试者) for the doctor’s degree.
Generally, however, modem examinations are written. The written examination, where all students are tested on the same questions, was probably not known until the nineteenth century. Perhaps it came into existence with the great increase in population and the development of modem industry. A room full of candidates for a state examination timed exactly by electric clocks and carefully watched over by managers, looks like a group of workers at an automobile factory. Certainly, during examinations teachers and students are expected to act like machines.
One type of test is sometimes called an “objective” test. It is intended to deal with facts, not personal opinions. To make up an objective test, the teacher writes a series (一系列)of questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like answers to students who have not learned the material properly.
4. The main idea of Paragraph Three is that ________.
A. workers now take examinations B. the population has grown
C. there are only written exams today D. examinations are now written and timed
5. The kind of exams where students must select answers are
A. objective B. personal
C. spoken D. written
6. Modem industry must have developed ________.
A. around the 19th century B. before the Middle Ages
C. in Greece or Rome D. machines to take tests
7. It may be concluded that testing ________.
A. should test only opinions B. should always be written
C. is given only in factories D. has changed since the Middle Ages
When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate(照亮)me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.
When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:“Let’s start with a train whistle today.” We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped.
When I lived for a time in London, I had a friend, He was in despair(失望)and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other.
For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think:“Yes, I must tell….”We have never met.
It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist(心理学家),who will only fill up the healing(愈合的)silence necessary to those darkest moments in which I would rather be my own best friend.In the eighth grade, what the author did before developing proper social behavior was to ______.
A.become serious about her study | B.go to her friend’s house regularly |

C.enjoy writing to each other | D.dream of meeting each other |
In the darkest moments, the author would prefer to ______.
A.seek professional help | B.be left alone |

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically(身体上).
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.From Paragraph 1, we learn that ________.
A.diet products fail to bring out people’s potential | |
B.people have difficulty in choosing diet products | |
C.diet products are misleading people | D.people are fed up with diet products |
One psychological effect of diet products is that people tend to _____.
A.try out a variety of diet foods | B.hesitate before they enjoy diet foods |
C.pay attention to their own eating habits | D.watch their weight rather than their diet |
In Paragraph 3, “gain comes without pain” probably means ______.
A.losing weight is effortless | B.it costs a lot to lose weight |
C.diet products bring no pain | D.diet products are free from calories |
Diet products indirectly harm people physically because such products ______.
A.are over-consumed | B.lack basic nutrients |
C.are short of chemicals | D.provide too much energy |
