单选题 Water makes up some 70 percentage points of the body, and drinking enough water-either tap water or expensive mineral water-will ensure that the body is properly lubricated and flushed.
A. per-cent B. per capita C. percent D. percentage

【正确答案】 C

【答案解析】[解析] 本题考查习惯搭配。句意为：水占了身体比例的70%，又能用足够的水——不管是自来水还是昂贵的矿泉水——都能确保身体的滋润和兴奋。percentage points“百分点”百分之几通常用“num+percent of+noun”表示。所以，答案是C。
