Question

【題目】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.

Answer 1

【答案】

【1】C

【2】A

【3】D

【4】B

【解析】

試題分析：文章介紹了最近的研究表明維他命D可以降低患癌癥的幾率，并且告訴了讀者幾種獲取維生素D的方法。

【1】C 細(xì)節(jié)理解題。根據(jù)第一段專家所說(shuō)的話take more vitamin D to lower risk of cancer可知，多吃維他命D可以降低患癌癥的幾率。故選C。

【2】A 推理判斷題。根據(jù)第二段中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.可知，Garland應(yīng)該是一名健康研究人員。故選A。

【3】D 細(xì)節(jié)理解題。根據(jù)第二段中的urging governments and public health officials to do more to fortify foods with vitamin D.在食物里增加vitamin D 和“Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses”，可知，在milk, fortified orange juice, yogurt and cheeses都能找到Vitamin D。故以上三項(xiàng)都可以降低人們患癌的機(jī)率。選D。

【4】B 推理判斷題。根據(jù)最后一段中的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.可以推斷，非洲人由于他們的膚色應(yīng)該多攝入維生素D。故選B。
