Question

【題目】Recently American researchers suggested 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 (增強(qiáng)) 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 particularly 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.

試題分析：本文講述的是科學(xué)家們正式增加對(duì)維他命D的補(bǔ)給對(duì)身體健康有很大的作用。

【1】詞義猜測(cè)題。A.收入 B.消化 C.淹沒(méi) D. 攝取。根據(jù)文章的意思是增加對(duì)維他命D的攝取，故選D

【2】細(xì)節(jié)理解題。Garland 主要做的研究是關(guān)于攝取維他命D對(duì)人體健康的影響，所以他很可能是一名健康研究專員，故選C

【3】細(xì)節(jié)理解題。文章第一段說(shuō) take more vitamin D to lower risk of cancer，多攝取維他命D可以降低癌癥的風(fēng)險(xiǎn)，故選D

【4】細(xì)節(jié)分析題。前文說(shuō)多攝取維他命D可以降低癌癥的風(fēng)險(xiǎn)，第二段又說(shuō)milk、Fortified orange juice、 Fortified yogurt里面都含有維他命D, 故選D

【5】細(xì)節(jié)分析題。文中說(shuō)people living in northern areas, which receive less vitamin D from sunshine.住在北方地區(qū)的人因?yàn)榻邮艿娜諘褫^少所以需要更多攝取維他命D，故選A
