Question

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.

Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.

People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.

Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.

It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.

【解析】

试题分析：本文是一篇科普短文。自从二十世纪三十年代动画片《大力水手》的播映以来，菠菜成了人们餐桌上必不可少的一道菜，人们都认为菠菜所含的铁会赋予人力量。事实上，菠菜里含的铁并不比别的蔬菜多，而菠菜中的叶酸能够使人身体强壮。

1. 主旨大意题。A 大力水手；B菠菜的真相；C数据的错误；D叶酸让你强壮。文章的开头点明《大力水手》的播映使很多人认为菠菜会让人强壮，接下来又指出this is not true，在第三、四、五段中作者讲述了有关菠菜的事实，由此可知文章的大意是纠正人们对于菠菜的错误认识，故选B。

2. 推理判断题。根据第一、二两段的内容可知，动画片中的大力水手吃了菠菜后力大无穷，看过这个动画片的人们也把菠菜当成了他们餐桌上一道必不可少的菜，由此推断人们认为菠菜真的会让他们身体强壮，故选A。

3.细节理解题。根据文章第三段倒数第二句“This group said that spinach had ten times more iron than it did.”可知研究者提出了菠菜中铁的含量是其他绿色蔬菜的10倍多的观点。D项表述正确，故选D。

4.细节理解题。根据文章最后一段的“It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.”可知叶酸能让人身体强壮，或许大力水手的力量就是由此而来的，故选B。

5.A推理判断题。根据文章第四段“spinach does have something else which the body needs—folic acid.”可知folic acid（叶酸）是存在于菠菜中的，但不是一种蔬菜，也不是一种菠菜，文中也没有提到叶酸有害，由此推断B、C、D均不正确，故选A。
