问题     For centuries, men and women have worked tirelessly to fit the physical molds of their time. Diets, which have【B1】______ from the【B2】______ to the colorful and kind of silly, have【B3】______ a wide range of results—and all sorts of followings.   
    Not long ago, the Atkins diet made carbohydrates wicked and convinced millions to【B4】______ starches of any kind. Today, the Paleo diet, which means to【B5】______ the eating habits and digestive systems of ancient humans who lived for many【B6】______ years than people on average do today, is【B7】______ the most popular—or at least talked about— dietary fad. Soon there will be another fad that the dieting sweeps【B8】______ . And another one.
    The question that seems to revolve【B9】______ all this diet talk is whether any of the【B10】______ weight loss schemes has worked. If one had, shouldn’t it have【B11】______ the test of time? And if we’ve gone this long【B12】______ a diet that has been shown to work— according to science, not simply the sellers of the fad—will one ever emerge【B13】______ actually does?
    The short answer is no, according to Traci Mann, who has been studying eating【B14】______, self-control and dieting for more than 20 years. 【B15】______ the course of her research, largely 【B16】______ at the University of Minnesota’s Health and Eating Lab, Mann has【B17】______ asked these sorts of questions, and always found the same【B18】______ answers. Her findings, introduced in her newly published book Secrets from the Eating Lab, offer a fascinating【B19】______ for why dieting over the long term is actually【B20】______.
【B17】
选项 A、constantly
B、repeatedly
C、habitually
D、irregularly
答案B
解析 从微观角度看，repeatedly与下文的always照应，从宏观角度看，Mann对过去各种节食手段的效果都进行了审视。副词repeatedly正好表达出这种频度。选项[A]constantly(一直，不变)侧重于“(在某段时间内)恒定，不变”，不如repeatedly贴切。选项[C]habitually(依习惯地，习惯性地)和[D]irregularly(不规则地)显然不符合上下文的含义。
