　　标准答案：BADFE

1.B.B中的Their与前句中的mins呼应;而后句的句意(没有这些物质,食物的碎化和吸收就不能进行。)揭示前句的内容应该是在谈论Vitamins的“好处”,同时B中metabolism与后句中提到的“食物的碎化和吸收”呼应。

2.A.A在句意上总领后面两句：后面两句分别是在对fat-soluble(溶解脂肪的)vitamins 和 water-soluble(溶解水的) vitamins进行解释。

3.D.该段的核心词(反复出现词)是vitamin A,而后句谈到vitamin A缺乏会造成的问题。在句意上与后句句意相关：一正(功效)一反(缺乏的后果)。

4.F.前句说到Vitamin A能如何被获得,而F在句意上与之相呼应：谈及Vitamin A“还能”怎样被获得。

5.E.空格前句说vitamin E在人体中的功能还没有被确认,后句说vitamin E在哪里能找到,同C相比,E更合理：E的句意也是表明vitamin E的“不确定的”功效,在句意上前后承接,而C只是笼统的说vitamin E是有必要的。
