vitamin(维生素) D every day, but this
vitamin is very important for our health.
Vitamin D is really important for our
bones(骨骼). When we are young, vitamin
D builds up our bones and makes them
strong. When we are older, we still need
vitamin D to keep our bones strong. Our
bodies keep vitamin D in our bones and
teeth. Then we lose vitamin D as we work
and exercise during the day. Our bodies
can't make vitamin D, so we have to get it
from outside of our bodies.
Vitamin D is in food like fish and eggs.
Sometimes, vitamin D is added to bread,
milk and orange juice. Food is not the only
way that our bodies get vitamin D. The sun
also gives us vitamin D. If we want to be

in the sun each day.

这是一篇以细节查找为核心的英语阅读理解题，解题思路非常清晰：首先根据题干给出的定位提示、关键词回到原文对应位置，将原文表述和各个选项逐一比对，排除和原文内容不符的错误选项即可选出正确答案。第9题围绕维生素D的作用定位对应段落找功能描述；第10题抓住“从体外获取维生素D”的关键词定位原文找因果关系的语句；第11题锁定“每天晒太阳时长”的关键词找原文的数值描述；第12题通读指定段落梳理核心内容，匹配对应主旨选项即可。
【解析】
9. 细节理解题：原文明确提到“Vitamin D is really important for our bones. When we are young, vitamin D builds up our bones and makes them strong”，说明维生素D可以让骨骼强壮，A“对心脏有害”、B“对牙齿没有必要”、C“让头发保持干净”的表述原文均无依据，因此选D。
10. 细节理解题：原文直接给出因果句“Our bodies can't make vitamin D, so we have to get it from outside of our bodies”，说明人体自身无法合成维生素D，所以必须从体外获取，A、B选项原文没有相关表述，D“只能从食物中获取维生素D”表述错误，晒太阳也可以获得，因此选C。
11. 细节理解题：原文最后一句明确说明“If we want to be healthy, we should spend about 15 minutes in the sun each day”，对应每天需要晒太阳约15分钟的表述，因此选A。
12. 段落大意题：第三段先后介绍了从鱼类、蛋类、添加了维生素D的面包、牛奶、橙汁等食物中获取维生素D，还可以通过晒太阳获取维生素D，整段都在介绍获取维生素D的不同途径，因此选B。
