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， 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 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_________.

A．it is nutritious

B．it can‘t harm people’s health

C．it is not taken enough every day

D．it can lower cancer risk

Which of the following can not help people get more Vitamin D？

A．Have more meat	B．Have some sunshine
C．Have a vitamin supplement	D．Have more fortified cheese

Who can Garland probably be？

A．A scientist	B．A health researcher
C．A doctor	D．A public health official

Which of the following food can lower people‘s chance of getting cancer？

A．Fortified orange juice	B．Milk
C．Fortified yogurt	D．All of the above

People from which area should take more Vitamin D according to the passage？

A．Asian people	B．American people
C．European people	D．African people

One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend. “One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mother-tongue education is not practiced in any of the independent African states.” said Neville Alexander, Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town.
In response to the spread of English and the increased multi-language trends arising from immigration, many countries have introduced language laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions was the 1994 “Toubon law” in France, and the idea has been copied in many countries since then. Such efforts to govern language use are often considered as futile by language experts, who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.
It is especially difficult for native speakers of English to understand the desire to maintain the “purity” of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world. But that has not been a barrier to acquiring superiority and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it has never been the Anglo-Saxon way of doing things. English has never had a state-controlled authority for the language, similar, for example, to the Academic Francaise in France.
The need to protect national languages is, for most western Europeans, a recent phenomenon- especially the need to ensure that English does not unnecessarily take over too many fields. Public communication, education and new ways of communication promoted by technology, may be key fields to defend.

A. the independence of African states          B. economic failure
C. globalization                                        D. multi-language trends

3. Why do many English-speaking countries not support the language protection efforts?

　B. They want their language to spread to other countries.

Stopping teens from smoking is a big challenge many communities face today. Many communities can only watch without being able to act while local businesses continue to sell tobacco products to children, even under the risk of punishment by law.
Recent studies show that a large percentage of teens today are getting their cigarettes from stores, mostly gas stations or convenience stores. As teens continue to be able to buy their own cigarettes, more and more communities begin to punish those who sell cigarettes to the teens.
One community has experienced success in their attempts to stop the sale of tobacco products to children. Woodridge, Illinois, started a program seven years ago which forbade and strictly punished the sale of tobacco products to children. The entire program includes local licensing of vendors (小贩), repeated undercover inspections to see if the sale to children has stopped, and education programs in schools. Woodridge has become a model community as other communities are moving to stop teen tobacco use.
A recent national study showed that 36.5% of females, and 40.8% of males buy their cigarettes from stores, whether it is a gas station or a supermarket. Hopefully, as more and more sellers see the trouble they face if caught selling to children, they will stop selling.
True, tightening down on stores that sell tobacco to children isn’t going to completely stop the problem of teen tobacco use. Teens continue to get them from other sources. But it definitely does prevent their efforts. With more education in schools, and perhaps stronger punishments for teens caught with tobacco, more and more teens will see the problems with the tobacco usage, and will stop the habit.
1. To stop teens from smoking, more and more communities are ________.
A. punishing those who sell cigarettes to teens more severely
B. punishing teens caught with tobacco more severely
C. educating those who sell cigarettes about the danger of teen smoking
D. stopping the sale of tobacco products in stores
2. Which of the following is NOT a way Woodridge uses to stop tobacco sale to children?
A. Local licensing to tobacco sale.        B. Repeated undercover inspections.
C. Education programs in schools.              D. Stronger punishment of teens caught smoking.
3. It can be inferred from the passage that _____________.
A. teens can only buy cigarettes from gas stations and convenience stores
B. more communities have succeeded in stopping teen tobacco use
C. More males than females have the habit of smoking in America
D. Punishment alone cannot solve the problem of teen tobacco use
4. What attitude does the writer have towards stopping teen tobacco abuse?
A. Negative        B. Optimistic     C. Uncertain      D. Uncaring

Music died here last spring, or rather, it was killed by members of the school committee who ignored the importance of music and drama as part of the high-school curriculum.
The committee decided that teaching students how to take a standardized test is more important than a curriculum in which students can explore their interests in the arts as well as academics. Because the school system is running out of funding, it needs to make sure that students pass the mastery test or even more money will be lost. If students fail the state standardized test, it is not the fault of drama and music classes – they are failing because the academic classes are not sufficient (足够).
It is painful to think of how many students will be discouraged from singing, acting, and playing instruments because school programs are no longer offered. Many families cannot afford private music lessons, and many potential musicians and artists may not find their calling if they are not exposed to it in school. The fact that the school committee thinks the arts are not worth the investment will certainly make some students believe the arts are not worth their time or support and the cycle will continue.
Teaching for a test does not shape students into complete, well- rounded people. It blocks the natural sense to create and express feelings through art – there is more to life than the analytical thinking that math and English provide. What happens after a test? Sure, a student might graduate, but they will have limited knowledge – certainly not a good preparation for the real world.
1. Music and drama are ignored by ________.
A. students       B. the school committee       C. teachers             D. parents
2. Which of the following is TRUE according to the passage?
A. Students can get high marks in the standardized test only by attending classes
B. The school committee completely influences students’ attitude towards the arts
C. Students can be musicians and artists only if they can afford private music lessons
D. Quite a few students are discouraged from music and art in today’ s school system
3. We can learn that music and art can ______.
A. provide students with analytical thinking
B. make students round-shaped people in future
C. motivate students in creativity and expression
D. prevent students graduating from high school
4. The best title of the passage can be ______.
A. Who Killed Music and Drama?               B. Can Curriculum Go Without Arts?
C. Why is Music So Important?                  D. How to Prepare For the Real World?

Botany, the study of plants, occupies a special position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest (含糊的) of insight. It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of peoples, not only for food, but also for clothing, weapons, tools, eyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognized accurately hundreds of plants and know many properties of each. To them, botany, as such, has no name and is probably not even recognized as a special branch of knowledge at all.
Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer productions the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the wonder of agriculture; cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the built up knowledge of tens of thousands of years of experience and close relationship with plants in the wild would begin fade away.
1. Which of the following statements about early humans is expressed in the passage?
A. They probably had extensive knowledge of plants.
B. They thought there was no need to cultivate crops.
C. They did not enjoy the study of botany.
D. They placed great importance on the ownership of property.
2. What does the comment “This is logical.” In the first paragraph mean?
A. There is no clear way to determine the extent of our ancestor’s knowledge of plants.
B. It is not surprising that early humans had a detailed knowledge of plants.
C. It is reasonable to assume that our ancestors behaved very much like people in pre-industrial societies.
D. Human knowledge of plants is well organized and very detailed.
3. According to the passage, why has general knowledge of botany begun to fade?
A. People no longer value plants as a useful resource.
B. Botany is not recognized as a special branch of science.
C. Research is unable to keep up with the increasing numbers of plants.
D. Direct contact with a variety of plants has decreased.
4. In the second paragraph, what is the author’s purpose in mentioning “ a rose, an apple, or an orchid”?
A. To make the passage more poetic.
B. To give an example of plant that are attractive.
C. To give botanical examples that all readers will recognize.
D. To explain the variety of botanical life.
5. According to the passage, what was the first great step toward the practice of agriculture?
A. The invention of agricultural tools and machinery.
B. The development of a system of names for plants.
C. The discovery of grasses that could be harvested and replanted.
D. The changing diets of early humans.
