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.
【C10】
选项
A、modest
B、prominent
C、subordinate
D、alternative
答案
A
解析
从空格后冒号的内容可以看出,在各种各样的复合维生素中,只有强化复合维生素 (stress multivitamins)对心脏病有预防作用,并且预防效果也并不突出(只降低25%的几率),由此可认为复合维生素预防心脏病的效果相当有限。A项modest有“适度的,有限的”意思,代入后可表示复合维生素有一定的预防作用。B项prominent“突出的,显赫的”代入后表明复合维生素对预防心脏病的作用很明显,这与下文语义不一致。C项subordinate “次要的”代入后表示此处提到的服用复合维生素的“好处”不如其他发现重要,这与常理不符。D项alternative意为“可供选择的”,代入后可表示服用复合维生素还有另外的功效,但是文章缺乏相关的语义线索。
