When it comes to eating smart for your heart, 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 ad you lift __67__ your mouth. "In the past we used to believe that __68__ amounts of individual nutrients (营养物) were the __69__ to good health," Linda Van Horn, chair of the American Heart Association's Nutrition Committee. "But now we have a __70__ understanding of healthy eating and the kinds of food necessary to __71__ not only heart disease but disease __72__ general," she adds.
Scientists now __73__ on the broader picture of the balance of food eaten __74__ several days or a week __75__ than on the number of milligrams (毫克) of this or that __76__ at each meal.
Fruits, vegetables and whole grains, for example, provide nutrients and plant-based compounds __77__ for good health. “The more we learn, the more __78__ we are by the wealth of essential substances they __79__," Van Horn continues, "and how they __80__ with each other to keep us healthy."
You'll automatically be __81__ the right heart-healthy track if vegetables, fruits and whole grains make __82__ three quarters of the food on your dinner plate. __83__ in the remaining one quarter with lean meat or chicken, fish or eggs.

这是一篇关于科学饮食的科技新闻。
为了让学生快速进入语境，文章第一段没有挖空。
从第一段中，我们可以获得全文主旨：科学饮食的真谛是从大处着眼，
67. 第二段首句有个定语从句：科学饮食远不止分析每一口放到嘴里的饭。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 表示在某某之间，不合题意。inside 表示静态，与lift这个动作相矛盾。同理，B选项through，表示穿过，lift这个动作，到嘴边就结束了，并没有穿过嘴巴。
73. 需要一个动词和on搭配，语法上四个选项都可以搭配，只能从词义上判断，turn on 表示打开，focus on 表示注重，put on 表示穿衣，carry on 表示执行。根据宾语，“更广的层面”，可知应该选择focus on。
74. 需要一个和“时间段”搭配的介词，over a period of time 表示一段时间以来，符合题意。
75. 这里表示“是什么而不是什么”，应该用rather than 才能准确达意。
76. 这是个分词短语作后置定语修饰前面的“this or that”，这里的this or that代指食物。convey是表达，不搭配。enter 可以表示“输入，记下”，也不和食物搭配。和食物搭配的只有B和D，consume表示，消费或消耗。exhaust 表示耗尽。很明显，这里的食物并不会耗尽，所以只能选B选项。
这里我们可以回过头来，看一下第68题，文章的主旨是，“Scientist now focus on the broader picture of the balance of food eaten over several days or a week”即“科学家现在注重最近几天内的均衡饮食”，与此能够形成对比的，“单个营养元素的定量摄入”，这里能表达特定量的词只有“certain”或者“specific”，这里用certain更自然，但是没有提供选项，因此就只能选择specific，表示“特定的”。
77. 需要个形容词，做后置定语，和for good health 搭配，这里只有vital 能和for搭配，表示“对…重要”。
78. 这里是一个 The more…the more 的固定表达，表示“越……越……”，这里用amazed表达科研人员，对新发现所产生的“惊奇之感”。
