An unsettling fact about lung cancer is that even clean living can not guarantee a free pass. A significant【C1】______of cases—10 to 15 percent— occur in people who【C2】______smoked, and just in the United States, 16 000 to 24 000 a year【C3】______.
What【C4】______the disease in nonsmokers is not known. A huge new study【C5】______in Europe, North America and Asia,【C6】______on 2.4 million nonsmokers who had【C7】______cancer, provides new information about just who is【C8】______risk. Male nonsmokers are more likely than【C9】______nonsmokers to die of the disease, the study found, and the overall risk to nonsmokers is not increasing.
"Concerns have been【C10】______that the risk was higher in women and that the risk was increasing,【C11】______this study counters those two misperceptions," said Dr. Michael J. Thun, the lead author of the study and the head of epidemiologic (流 行病学的)research for the American Cancer Society. The study is being【C12】______online in PLoS Medicine.
Dr. Thun【C13】______that although nonsmokers do have some risk, smokers are much【C14】______off: a man who never smoked has a 1.1 in 100 risk of dying【C15】______lung cancer, but it jumps to 1 in 5 if he【C16】______In women, the risk goes from 0.8 in 100 to 1 in 8. The figures【C17】______, depending on how much a person smokes.
The study found that among【C18】______who never smoked, Asians living in Asia (not those in the United States) and African-Americans had higher【C19】______of illness and death from lung cancer than did people of European【C20】______.
【C20】
选项
A、descent
B、country
C、area
D、region
答案
A
解析
名词辨析题。descent有“家系,血统”的意思,此处表示具有欧洲血统的人,故A)符合题意。country、area和region分别表示“国家”、“区域”和“地区”的意思,并且是单数,不符合题意。
