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.
61. 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 can lower cancer risk      D. it is not taken enough every day
62. Which of the following can not help people get more Vitamin D?
A. Have some sunshine        B. Have more meat
C. Have more fortified cheese   D. Have a vitamin supplement
63.Who can Garland probably be?
A. A health researcher        B. A doctor
C. A scientist               D. A public health official
64.Which of the following food can lower people‘s chance of getting cancer?
A. Milk                    B. Fortified orange juice
C. Fortified yogurt           D. All of the above
65.People from which area should take more Vitamin D according to the passage?
A. Asian people               B. African people
C. American people            D. European people

Research shows that childhood friendships are important indicators of future success and social adjustment. Children's relationships with peers (同龄人) strongly influence their success in school, and children with fewer friends are more likely dropping out of school, becoming sad and other problems.
Making and Keeping Friends Is More Than Child's Play
When 6-year-old Rachel returned to school on a recent Monday morning, her eyes immediately scanned the playground for her friend Abbie. Though they were only separated by a weekend, the girls "ran right into each other's arms and hugged," recalls Rachel's mother Kathryn Willis of Gilbert. "It was like a scene from a movie."
Most parents instinctively (本能地) know that having friends is good for their child. Experts agree that friendship is not simply child's play, but a powerful predictor of social adjustment throughout life.
A Skill for Life
"Childhood friendships serve as a very important training ground for adulthood," says Dr. Robbie Adler-Tapia, psychologist with the Center for Children's Health & Life Development.
Researcher William Hartup states, "Peer relations contribute significantly to both social and cognitive (认知的) development." Hartup concludes that the single best childhood predictor of adult social adaptation is not school grades or classroom behavior, but rather, how well a child gets along with other children.
The work of Arizona State University proves that just as being able to make and keep friends is beneficial to kids, so is the lack of friends detrimental.
Good Friendships Don't Just Happen
Experts agree that it is basic for children to develop high-quality friendships. But, researchers warn, these friendships don't necessarily just happen. Often, a good friendship begins with involved （卷入，牵连）parents.
Valley psychologist Dr. Lynne Kenney Markan believes kids should be taught social skills in much the same way they are taught math and reading.
Bad Company
Many parents worry about the quality as well as the quantity of their child's friendships. "When she was in 1st grade, her supposed 'best friend' began calling her names and threatening to hurt her," says Mindy Miller. "My daughter wasn't allowed to talk to or even look at other girls in her class. It really crushed (压跨) her spirit. I told my daughter she didn't need a 'friend' like that."
"I'll bend over backwards to help my son get together with a friend I think is good for him," Adler-Tapia says. "I don't look at it as manipulation (操纵), just positive parental involvement. "
【小题1】The example of Rachel and Abbie is used to show that ________.

A．childhood friendship is of great benefit to their growth

B．a positive friendship helps children solve emotional and physical problems

C．it is a proven（被证明的） fact that peer friendship is the most rewarding experience throughout life

D．Rachel missed her friend Abbie very much because of their separation of one weekend

【小题2】The underlined word "detrimental" could be replaced by _______.

【小题3】We can learn from the passage that high-quality friendship most probably results from ______.

A．social skills and good study habits

B．school grades and classroom behaviors

C．academic success and social adaptation

D．positive parental involvement and social skills

【小题4】From the last paragraph we can conclude that Dr. Robbie Adler-Tapia agrees that ______.

A．parents should regard making friends as something that just happens

B．it's wise for parents to support and encourage healthy peer relationships

C．parents only need to help their children to deal with difficult social situations

D．parents are supposed to encourage their children to make as many friends as they can
