单选题
It is very plain that such a life as this is far more______to health than that of the man who can afford little leisure for necessary rest in the course of the day.
【正确答案】
D
【答案解析】[解析] 空格处意为“这更有益于健康”。be conducive to…意为“有益于……”，如： Fresh air is conducive to health．(新鲜空气有助于健康。)其他三项“conductive传导的； constructive建设性的；conciliate安慰，赢得，调和”都与句意不符，因此正确答案为D。
