一份视力研究报告

陈望珍

语篇导读

近视被列为世界三大疾病之一。目前，全世界近视率达22%，而我国患近视人数近4亿，近视率为33%，青少年患近视的约2.7亿，且每年新增近视者约为6%。那么，近视与什么有关？怎样可以降低近视率呢？英国科学家经过研究得出了结论，并提出了合理的建议。

Are you short-sighted？ As we all know， it？蒺s bad for our eyes to use mobile phones and watch TV too much. It is said that eyesight also has something to do with the time to get an education. Is it true？

The more years you spend in full-time education， the more short-sighted you are likely to be， according to a large UK study.

The study is carried out by Cardiff and Bristol University scientists. They analysed （分析） information on the genetics （遗传学）， eyesight and educational background of 68，000 people in the UK. They wrote a report and sent it to a medical magazine in England.

The report tells that a person who spent 17 years on education is more short-sighted（近视） than someone who left school at the age of 16 after spending 12 years on education. It？蒺s about on average more than 100 degrees. The degrees mean the difference between having perfect eyesight and needing glasses to drive safely.

“In the world， the number of short-sighted people is more and more. And bad eyesight may cause other illness. The findings of this study are important and meaningful for educational practice.” said the scientist Jez from Cardiff University.

They found that the number of years at school and college strongly influenced eyesight， but there was no effect in the opposite direction. If someone is short-sighted， that will not lead him to remain in education for longer.

Don？蒺t worry！In fact， the reason is that students have too little time to stay in the bright natural light. And the advice from the scientists is for children to spend more of the day outdoors.

典句赏析

1.The more years you spend in full-time education， the more short-sighted you are likely to be， according to a large UK study.英國一项大型研究显示，你接受全日制教育的时间越长，你的近视度数的可能性就越高。

“the+比较级……，the+比较级……”是一个复合句句型，表示“越……就越……”，前一个“The more...”相当于比较状语从句，后一个“the more...”相当于主句。

2.The report tells that a person who spent 17 years on education is more short-sighted than someone who left school at the age of 16 after spending 12 years on education.报告显示，一名受过十七年教育的人，比一名十六岁就辍学、受过十二年教育的人的近视度数要高。

这是一个含that引导的宾语从句的复合句，在宾语从句里又包含两个定语从句，who spent 17 years on education is more short-sighted修饰先行词person，who left school at the age of 16 after spending 12 years on educa-ion修饰先行词someone。

3.They found that the number of years at school and college strongly influenced eyesight， but there was no effect in the opposite direction.他們发现，虽然在中小学和大学学习的时长对视力有很大的影响，但反过来却不成立。

that在这里作连接代词引导宾语从句，该从句又是由but连接的两个并列分句。
