Question

【题目】阅读理解

A

A big bowl of milk can be a great way to start the day. Many snack bars contain nutrients that help our bodies stay strong and healthy. But some of these foods are packed with too many vitamins and minerals. According to a new study by the Environmental Working Group (EWG), this extra fortification may be more harmful than helpful.

Of the tested snack bars, 27 have more than 50% of the recommended amounts of vitamin A, niacin and zinc. Nutrition facts listed on packages are based on recommended daily values for adults, who are physically larger and require more vitamins and minerals. So when kids eat these cereals (麦片) and snack bars, they are getting more nutrients than they need.

Vitamin A, niacin (烟酸) and zinc (锌) are best in fresh and unprocessed foods that are in their natural state. Vitamin A helps you see at night. It occurs naturally in eggs, meat and carrots. Niacin is a vitamin that helps our bodies make energy. It is found in foods like fish, seeds, and peanuts, as well as in whole grains like wheat and brown rice. Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans and nuts.

Children typically eat more than one serving of cereal or snack bars a day, in addition to taking vitamin supplements. Eating large amounts of these nutrients can be dangerous to kids’ health. Too much vitamin A can cause liver damage, and high levels of zinc can destroy the body’s natural immunity, or power to fight infection.

The EWG authors are calling for the FDA to make changes to its guidelines for nutrient intake and revise its daily values to match kids’ diets.

【解析】本文是议论文。文章通过对孩子饮食现状的研究和调查可知，过量营养对孩子们有很大的坏处，专家认为，这种情况需要得到有效的控制。

【1】 B 推理判断题。该段介绍了研究的情况，特别是联系第四句及最后一句So when kids eat these cereals and snack bars, they are getting more nutrients than they need，可知，孩子需要的营养比成年人要少，故正确答案为B。

【2】A 推理判断题。文章第三段介绍了营养对健康的好处，根据其中Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans, and nuts可知，要避免感染需要吃富含锌的食物，包括肉和坚果。

【3】 C 推理判断题。本段主要介绍了过量营养的坏处，这样C项符合题意。根据该段第二句中的Eating large amounts of these nutrients可知，孩子们也许喜欢吃这些东西，但这不是作者想要告诉读者的段落思想，故A项错误。

【4】 A 主旨大意题。本文主要介绍了营养和孩子们的健康的关系，侧重于过量营养对健康的负面的作用，据此可以推知，A项为本文最佳标题。联系主题思想，本文不是介绍三大营养，所以C项不对。
