试题详情及答案解析

There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes.
We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight.
Another myth about eyes is that they can be replaced, or transferred from one person to another. They are close to one million nerve fibers(纤维) that connect the eyeball to the brain, so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible.

试题分析：文章主要纠正了一些关于眼睛的错误观念。一些被人们普遍接受的关于戴眼镜的观念证明是不真实的。从很小的年纪就开始戴眼镜不会改变眼睛的结构。
【小题1】细节理解题。根据第一段“But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age.”可知，没有证据能够证明从很小的年纪开始戴眼镜会改变眼睛的结构，即过早配戴眼镜不会改变眼睛的结构，故选A。
【小题2】细节理解题。根据第一段“Wearing the wrong glasses...Studies show that for adults there is no danger”可知，成年人佩戴不合适的眼镜对他们的眼睛不会造成伤害，故选C。
【小题3】细节理解题。根据最后一段“so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced.”可知，把眼睛移植到另一个人身上是不可能做到的事情，只有眼睛的某个部分可以被替换或移植，故选A。
【小题4】写作意图题。根据第一段“There are many commonly held beliefs about eye glasses and eyesight that are not proven facts.”可知，一些被人们普遍接受的关于戴眼镜的观念证明是不真实的；根据第二段“Most people believe that reading in dim light causes poor eyesight, but that is untrue.”可知，大多数人所认为的在昏暗的环境中看书对眼睛有害是不真实的；根据第三段“Another myth about eyes is that they can be replaced, or transferred from one person to another.”可知，眼睛可以被替换或从一个人身上移植到另一个人身上的观点也是错误的，由此可知，文章主要纠正了一些关于眼睛的错误观念，故选B。
