?A study about eyesight

陳望珍（編）

◆語(yǔ)篇導(dǎo)讀

近視被列為世界三大疾病之一。目前，全世界近視率達(dá)22%，而我國(guó)患近視人數(shù)近4億，近視率為33%，青少年患近視的約2.7億，且每年新增近視者約為6%。那么，近視與什么有關(guān)？怎樣可以降低近視率呢？英國(guó)科學(xué)家經(jīng)過(guò)研究得出了結(jié)論，并提出了合理的建議。

Are you short-sighted?As we all know,it'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 shortsighted 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(遺傳學(xué)),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(近視)than someone who left school at the age of 16 after spending 12 years on education.It'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'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.

◆典句賞析

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(guó)一項(xiàng)大型研究顯示，你接受全日制教育的時(shí)間越長(zhǎng)，你的近視度數(shù)的可能性就越高。

“the+比較級(jí)……，the+比較級(jí)……”是一個(gè)復(fù)合句句型，表示“越……就越……”，前一個(gè)“The more...”相當(dāng)于比較狀語(yǔ)從句，后一個(gè)“the more...”相當(dāng)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.報(bào)告顯示，一名受過(guò)十七年教育的人，比一名十六歲就輟學(xué)、受過(guò)十二年教育的人的近視度數(shù)要高。

這是一個(gè)含that引導(dǎo)的賓語(yǔ)從句的復(fù)合句，在賓語(yǔ)從句里又包含兩個(gè)定語(yǔ)從句，who spent 17 years on educa tion is more short-sighted修飾先行詞person，who left school at the age of 16 after spending 12 years on educaion修飾先行詞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.他們發(fā)現(xiàn)，雖然在中小學(xué)和大學(xué)學(xué)習(xí)的時(shí)長(zhǎng)對(duì)視力有很大的影響，但反過(guò)來(lái)卻不成立。

that在這里作連接代詞引導(dǎo)賓語(yǔ)從句，該從句又是由but連接的兩個(gè)并列分句。
