问题     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.
【C16】
选项 A、chronic
B、emotional
C、acute
D、psychological
答案A
解析 在文章中，与研究发现相关的介绍总是把服用复合维生素和癌症、心脏病等疾病的诊断或发病率联系在一起，这类病属于慢性疾病。A项chronic“慢性的”搭配disease prevention意为“慢性病的预防”。文章没有与“精神”疾病(B项emotional)或“心理”疾病(D项psychological)相关的语义提示。C项acute“急性的，剧烈的”搭配disease意为“急性疾病”，文中所提的癌症、心脏方面的疾病等不属于急性病的范畴。
