Question

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.

【解析】

试题分析：文章介绍了最近的研究表明维他命D可以降低患癌症的几率，并且告诉了读者几种获取维生素D的方法。

1. 细节理解题。根据第一段专家所说的话take more vitamin D to lower risk of cancer可知，多吃维他命D可以降低患癌症的几率。故选C。

2. 推理判断题。根据第二段中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应该是一名健康研究人员。故选A。

3. 细节理解题。根据第二段中的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。故以上三项都可以降低人们患癌的机率。选D。

4. 推理判断题。根据最后一段中的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.可以推断，非洲人由于他们的肤色应该多摄入维生素D。故选B。

【名师点睛】

细节题的破解一般采用寻读法，即先看试题，再读文章。对有关信息进行快速定位，再将相关信息进行整合、甄别、分析、对比，有根有据地排除干扰项，选出正确答案。此法加强了阅读的针对性，提高了做题的准确率，节省了宝贵的时间。寻读法还特别适用于对图形表格类题材的理解。做此类型的题目还要特别注意句子的逻辑关系。英语中有许多功能词，如：表因果关系的because, since, as等；表转折关系的but, however ,on the contrary, on the other hand等等。比如第70小题D细节理解题。根据第二段中的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能找到Vitamin D。故以上三项都可以降低人们患癌的机率。选D。
