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.
【C12】
选项
A、definite
B、essential
C、significant
D、glorious
答案
C
解析
上文虽然提到强化维生素能在一定程度上降低女性的心脏病发作几率。但除了此项结论,没有给出其他支持维生素能防癌的结论。另外,本文的一个重要观点是复合维生素对癌症、心脏病以及其他疾病没有预防作用。由此可以推断:在维生素与健康之间的相互关系方面,没有其他的显著发现。C项significant“重要的,值得注意的”搭配statistically表示“有显著的统计意义”,符合语义要求。A项definite“明确的”、B项essential“必要的”和D项glorious“辉煌的”,这三项要么在语义上过于绝对,要么不与statistically搭配,故需排除。
