The news about vitamins keeps getting worse. Many studies published in the last few years shows that a variety of popular supplements don’t do anything to reduce the risk of developing heart disease, stroke or a variety of cancers.
But what about multivitamins? These combination pills, which【C1】________10 to 30 vitamins and【C2】________, are the most popular supplements sold in America. A report published recently suggests they shouldn’t be.
The study【C3】________161,808 participants in the Women’s Health Initiative, a long-term effort to【C4】________risk factors for cancer, heart disease and bone health in elderly women.【C5】________in the nationwide study included white, black, Asian and Native American women. They were followed for an average of nearly eight years.【C6】________, 41.5% of study participants took some version of a multivitamin. Those women were more likely to be white and college-educated, live in the West, exercise and have a lower body mass index.
However, women who took multivitamins weren’t any more likely to【C7】________a diagnosis of breast, lung, stomach, and other cancers than were women who didn’t take multivitamins. Nor were multivitamins in general helpful in【C8】________heart attacks, strokes or reducing the risk of death from any【C9】________during the study period. The research team did find one【C10】________benefit: The 3,741 women who took stress multivitamins—formulations【C11】________higher doses of several B vitamins along with an extra amount of vitamin C—were 25% less likely to have a heart attack. No other correlations between vitamins and health outcomes were statistically【C12】________.
The study provides【C13】________evidence that multivitamin use has little or no【C14】________on the risk of common cancers, heart disease or total mortality in elderly women.【C15】________, researchers wondered, "Why do millions of Americans use a daily multivitamin for【C16】________disease prevention when the supporting scientific data are weak?" Some physicians continue to【C17】________them for patients whose diets may have nutritional【C18】________. And since they don’t require a prescription, many people simply【C19】________they are safe. But those assumptions may not be【C20】________, especially if people wind up overdosing on vitamins and minerals, the researchers wrote.

选项
A、Subjects
B、Staffs
C、Designers
D、Interviewees
答案
A
解析
上一句子说明研究调查了161,808名参与者,可判断上句中的“参与者”就是此句宾语中提到的white, black, Asian and Native American women。换言之,这些女性是被研究的对象。A项Subjects“主体”代入此语境表示“研究对象”或“研究的受试者”,符合表达习惯。B项Staffs“工作人员”、C项Designers“设计者”都不能回指上句中的participants,不能满足语义和语境要求。D项Interviewees“受访者”指的是接受采访或面试的人,不符合文章的语境和逻辑要求,文章也未给出相关的语义提示。
