问题     When it comes to eating smart for your heart, stop thinking about short-term fixes and simplify life with a straightforward approach that will serve you well for years to come.
    Smart eating goes beyond analyzing every bite you lift 【B1】______ your mouth. "In the past we used to believe that 【B2】______ amounts of individual nutrients were the 【B3】______ to good health," Linda Van Horn, chair of the American Heart Association’s Nutrition Committee. "But now we have a 【B4】______ understanding of healthy eating and the kinds of food necessary to 【B5】______ not only heart disease but disease 【B6】______ general," she adds.
    Scientists now 【B7】______ on the broader picture of the balance of food eaten 【B8】______ several days or a week【B9】______than on the number of milligrams of this or that【B10】______at each meal. Fruits, vegetables and whole grains, for example, provide nutrients and plant-based compounds【B11】______for good health. "The more we learn, the more【B12】______we are by the wealth of essential substances they【B13】______," Van Horn continues, "and how they【B14】______with each other to keep us healthy."
    You’ll automatically be【B15】______the right heart-healthy track if vegetables, fruits and whole grains make【B16】______three quarters of the food on your dinner plate.【B17】______in the remaining one quarter with lean meat or chicken, fish or eggs.
    The foods you choose to eat as well as those you choose to【B18】______clearly contribute to your well-being.
    Without a【B19】______, each of the small decisions you make in this realm can make a big【B20】______on your health in the years to come.
【B1】
选项 A、between
B、through
C、inside
D、to
答案D
解析 考查介词辨析。根据语境可知，空格处所在句意为：科学饮食远不止分析放到嘴里的每一口饭。这里要选择一个介词，lift的原意是高举，在这里的意思就是“放到嘴边”，to表示方向。between表示“在…之间”，不合题意；inside表示静态，与lift这个动作相矛盾；同理，through表示“穿过”，lift这个动作，到嘴边就结束了，并没有穿过嘴巴，这三项均不符合题意。故选D．to。
