標準答案:BADFE
1.B.B中的Their與前句中的mins呼應;而後句的句意(沒有這些物質,食物的碎化和吸收就不能進行。)揭示前句的內容應該是在談論Vitamins的“好處”,同時B中metabolism與後句中提到的“食物的碎化和吸收”呼應。
2.A.A在句意上總領後面兩句:後面兩句分別是在對fat-soluble(溶解脂肪的)vitamins 和 water-soluble(溶解水的) vitamins進行解釋。
3.D.該段的核心詞(反覆出現詞)是vitamin A,而後句談到vitamin A缺乏會造成的問題。在句意上與後句句意相關:一正(功效)一反(缺乏的後果)。
4.F.前句説到Vitamin A能如何被獲得,而F在句意上與之相呼應:談及Vitamin A“還能”怎樣被獲得。
5.E.空格前句説vitamin E在人體中的功能還沒有被確認,後句説vitamin E在哪裏能找到,同C相比,E更合理:E的句意也是表明vitamin E的“不確定的”功效,在句意上前後承接,而C只是籠統的説vitamin E是有必要的。
