Many Americans have been feeding a baby aspirin once a day, believing it would protect them from a heart attack, a stroke, and even cancer. But several recent studies have 【C1】________this into question.
One large-scale study【C2】________more than 19,000 healthy people ages 65 and older. Participants were【C3】________assigned to take either 100 mg of aspirin (slightly more than the 81 mg dose that【C4】________people take) or a placebo (a harmless substance given to a sick person【C5】________medicine, without telling them it is not real) every day for an average of 4.7 years.【C6】________did people in the aspirin group not【C7】________their risk of heart disease, dementia, or disability, but they were also more【C8】________to suffer from significant bleeding in the digestive tract or brain. And they were more likely to die【C9】________apparently because of an increased risk of【C10】________cancer.
【C11】________, a trial of more than 12,500 people ages 55 and older【C12】________to have a moderate cardiovascular risk found no benefit to taking aspirin daily. In a study of more than 15,000 people with diabetes, a daily aspirin did【C13】________heart attacks and strokes, but it also【C14】________ major bleeding. And according to an analysis of data from more than 117,000 people,【C15】________ people needed larger doses of aspirin to help【C16】________their risk of heart attack, stroke, and cancer.
The bottom line: Although there is good【C17】________that aspirin can help people who have already had or are at【C18】________risk for heart attacks or strokes, the drug’s【C19】________is not so clear for people, especially older people, with less risk.【C20】________your doctor before starting—or stopping—aspirin.
【C14】
选项
A、resulted
B、led
C、influenced
D、caused
答案
D
解析
本题空格需要填入一个动词,作并列谓语,满足句意“每天服用阿司匹林确实能预防心脏病和中风,但它也会________严重出血。”前半句提到阿司匹林对心脏病和中风有预防作用,由连词but可知前后为转折关系,后半句应该提及阿司匹林的危害,it指代的是a daily aspirin,后跟宾语major bleeding(严重出血),两者之间应为因果关系,即每天服用阿司匹林会“引起”严重出血,四个选项中只有D项caused“导致,引起”符合句意,故为正确答案。A项resulted意为“导致”时,后面要跟介词in;B项led意为“导致”时,后面要跟介词to;C项influenced意为“影响”,选项A、B代入原文无法构成语法正确的语句,C项代入原文不符合句意,故排除。
