For young people, a moderate amountof physical activity every day is ___to good health.A. fabulousB. consecutiveC. allergicD. conducive

本题考查词汇辨析，解题思路是理解每个选项单词的含义，然后结合句子语境，判断哪个单词能使句子逻辑通顺。

• A选项“fabulous”：意为“极好的；惊人的”。若将其代入句子“For young people, a moderate amount of physical activity every day is fabulous to good health.”，“极好的”与“对健康”搭配不符合逻辑，不能说适度运动对健康是极好的这种表述，所以A选项不正确。
• B选项“consecutive”：意思是“连续的；连贯的”。把它放进句子“For young people, a moderate amount of physical activity every day is consecutive to good health.”，“连续的”和“对健康”无法构成合理的语义关系，所以B选项不合适。
• C选项“allergic”：表示“过敏的”。句子“For young people, a moderate amount of physical activity every day is allergic to good health.”，说适度运动对健康过敏，这显然不符合常理，所以C选项错误。
• D选项“conducive”：有“有助于；促成”的意思。“be conducive to”是固定短语，意为“对……有帮助；有助于……”。将其代入句子“For young people, a moderate amount of physical activity every day is conducive to good health.”，表达“对于年轻人来说，每天进行适量的体育活动有助于身体健康”，语义通顺合理，所以D选项正确。
