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.

Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.
Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.
Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died. w_w w. k#s5_u.c o*m
The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs. w_w*w.k*s_5_u.c*o*m
Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and he does not.

People with disabilities make up a large part of the population. It is estimated that over 35 million Americans have physical, mental, or other disabilities. About half of these disabilities are “developmental", i.e., they occur before the individual's twenty-second birthday, often from genetic conditions, and are severe enough to affect three or more areas of development, such as mobility, communication, employment, etc. Most other disabilities are considered “adventitious", i.e., accidental or caused by outside forces.
Prior to the 20th century, only a small percentage of people with disabilities survived for long. Medical treatment for these disabilities was unavailable. Advancements in medicine and social services have created a climate in which people with disabilities can expect to have such basic needs as food, shelter, and medical treatment. Unfortunately, these basics are often not available. Civil liberties such as the right to vote, marry, get an education, and gain employment have historically been denied on the basis of disability.
In recent decades, the disability rights movement has been organized to fight against these infringements(违反;侵犯)of civil rights. Congress responded by passing major legislation recognizing people with disabilities as a protected class under civil rights statutes.
Still today, people with disabilities must fight to live their lives independently. It is estimated that more than half of qualified Americans with disabilities are unemployed, and a majority of those who do work are underemployed. About two-thirds live at or below the official poverty level.
Significant barriers, especially in transportation and public awareness, prevent disabled people from taking part in society. For example, while no longer prohibited by law from marrying, a person with no access to transportation is effectively excluded from community and social activities which might lead to the development of long-term relationships.
Only when public attitudes advance as far as laws have will disabled people be fully able to take their rightful place in society.
1. A “developmental" disability ______.
A. develops very slowly over time
B. is caused by forces
C. occurs in youth and affects development
D. is getting more and more severe
2.Most disabled people used to die early because ______.
A. disabilities destroyed major bodily functions
B. they were not very well looked after
C. medical techniques were not available
D. they were too poor to get proper treatment
3. In the author's opinion, to enable the disabled people to take their rightful place in society, ______.
A.more laws should be passed
B.public attitudes should be changed
C.government should provide more aids
D.more public facilities should be set up
4. Which of the following cannot be inferred(推断)from the passage ?
A.Many disabled people may remain single for their whole life.
B.The public tends to look down upon the disabled people.
C.The disabled people feel inferior to those surrounding them.
D. Discriminatory laws prevent the disabled from mixing with others.
