Question

1．Nowadays，many children spend hours a day looking at computer screens or other digital （數(shù)碼的） products．Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome （視力綜合癥）．
Nathan Warford is an optometrist（驗(yàn)光師） in the US．He says he has seen more children having eye problems．"More children come into my office because their parents have noticed that they have headaches （頭疼）or red eyes，or because their degree of short-sightedness appears to be increasing （增加）very fast and they're worried，"he said．
Dr．Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache，some children don't tell their r parents，because they don't want their games or the computer to be taken away．Another part of the problem is that people blink （眨眼睛） less often when they look at the screen．A person who uses a computer or a digital product blinks about a third as much as we normally（正常地） do in everyday life．If eyes can't stay wet or are too tired，they will not be protected like normal．

Answer 1

分析 短文主要講述了當(dāng)今孩子們每天花費(fèi)數(shù)小時(shí)坐在電腦前看電腦屏幕以及其他的數(shù)碼產(chǎn)品，因此正如一些關(guān)愛視力的醫(yī)生們所說孩子們的這種行為已經(jīng)導(dǎo)致了視力綜合征的問題，同時(shí)醫(yī)生也在從兩個(gè)方面說明了這個(gè)問題疾病產(chǎn)生的原因．
