　　 答案与题解：
　　 1．D 第二段第二句及第三句说到，降低患病危险性的作用应该归功于果汁和全果均含有的纤维和抗氧化剂。其他A、B、(：三个选项文章均未提及。
　　 2．C 第三段第二句说到，在与慢性病的发生的关系方面，认为果汁不如全果有营养的观点是 unjustified(“不正当的”)，也就是“不正确”(incorrect)。
　　 3．B 第四段第二句说到，果汁在降低患各种疾病中的确起着重要作用，尤其是癌症和心血管疾病。这里in particular正是especilly的意思。
　　 4．A 第四段最后一句说到，饮用果汁也与降低患阿尔茨海默病的危险性有关。
　　 5．B 第五段第一句说到，每周喝3～4份果汁的人与每周只喝一次以下的人相比，其患阿尔茨海默病的危险性下降了76%，76%就是3/4，因此B项是正确答案。A项是高出23%，C项是每周喝一次的人的123%，D项是每周喝一次的人的176%，均不正确。
