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%，喝足够的水——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。
