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 (吸入，攝入), 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 (增強) foods with vitamin D. Garland is member of a team at San Diego Moores Cancer Hospital 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 units 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 color, could also benefit significantly from a higher intake,” the authors said.

Answer 1

【答案】

【1】C

【2】B

【3】D

【4】B

【解析】

試題分析：文章介紹了研究表明維他命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】細節(jié)理解題。根據(jù)文章中專家所說的話take more vitamin D to lower risk of cancer，可得知多吃維他命D可以降低患癌癥的幾率應該選擇，故C正確。

【2】 推理判斷題。根據(jù)文章的第一句話Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer可知這是研究人員的話，第一段的最后一句話Dr. Cedric Garland said in a telephone interview.可以推斷出： Dr. Cedric Garland是一個健康研究人員。故B項內容正確。

【3】 細節(jié)理解題。根據(jù)維他命D可以降低癌癥幾率，所以我們要找到可以獲取維他命D的來源Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, D項包含了這些食物。故D項正確。

【4】推理判斷題。根據(jù)最后一段“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.可以推斷出非洲人應該多攝入維生素D，故B項正確。
