5、3. to process； 4. are removed； 5. a； 6. worse； 7. is； 8. eating； 9. careful； 10. which【解析】句意：近来在食品服务行业有一种低脂肪低盐的趋势。这种趋势由医学界作为 一种抗心脏病的方式发起的。故填介词as,作为句意：这种趋势已经产生了一些意想不到的副作用，如超重和心脏疾病恰 恰是医学界想努力战胜的。side effect副作用。由some可知此处用名词的复数形 式，故填effects o句意：脂肪和盐是饮食中重要的组成局部。我们需要它们来加工我们所吃的食 物来恢复身体的伤害和其它几项身体功能。require s
6、b to do sth要求某人做某事, 此处用被动形式sb is required to do sth某人被要求做某事。故填to processo句意：当脂肪和盐被人们从食物中去掉以后，这些食物尝起来好像缺了什么东 西。fat and salt与remove之间构成被动关系，故用被动语态,所以填are removed 句意：因此，人们会吃更多的食物来弥补那些缺少的东西。词组：as a result 作为结果；因此。故填a。句意：更糟糕的是，人们吃的快餐的量就增加了。故填worse。句意：餐食物中充满了脂肪和盐。fast food的意思是“快餐”，表示一类食物, 为不可数名词，谓语动词用单数形式
7、。故填is。句意：通过吃更多的快餐，人们将在饮食中摄入超过需求量的脂肪和盐。by 是介词，后跟动词-ing形式表示“通过方式”，所以填eat的动名词形式。故 填 eating o句意：然而，注意不要走极端。be后面应该用形容词做表语，故填careful。句意：很可能摄入过多的脂肪和盐，那对健康没有好处。由后面的is not good for the health.可知此处需要关联词，通过分析可知这是一个非限制性定语从句， 先行词是前文中的have too much of both摄入过多的脂肪和盐”，故填which o 第二节阅读理解请认真阅读以下短文，从短文后各题所给的A、B、C、D四个选项
