Eye Problems
1 Our eyes are under a great deal of strain these days as computer work,television viewing,nightdriving,and even sunshine are making exceptional demands.Sunlight, especially in the summer, is now regarded as one cause of cataracts（白内障）.
2 The thinning of the ozone（臭氧）layer means more short-wave ultraviolet ( UV ) rays（紫外线） are reaching the earth,and these are the biggest risk factor for clouding the lens of the eye.Ultraviolet raysincrease the risk of changes to the cornea（角膜）causing clouded vision and eventually cataracts.The rays can be shielded only by anti-UV lenses.However, our eyes are not sufficiently protected byfashion sunglasses.
3 "Poor night vision and eye fatigue are noticeably more common,and there has been a big increase in minor eye complaints in the over-40s,"says Dr.Mireille Bonnet,who took part in recent research.She says that the six muscles controlling each eye move more than 100,000 times a day and that everyone should learn to exercise their eye muscles and allow them to rest.
4 It was traditionally thought that near- or far-sightedness were inherited conditions and could not be influenced by environmental factors,but new research is challenging this assumption.
5 Recent studies suggest that up to 80 percent of schoolchildren in the United States and western Europe are nearsighted.Years of focusing on close,two-dimensional work causes most children to become at least slightly nearsighted by the age of 10,say the researchers.
6 Problems with night vision,which affect around 25 percent of people,are also on the increase because of computer use.Using computer screens means the eye must operate in electromagnetic fields （电磁场）that make it work harder.It is estimated that 25 to 30 percent of people have eye conditions, such as difficulty with night vision,which result from staring at a screen.Over 25%of people are estimated to have difficulty with night vision due to______.
A:our parents
B:clouded vision
C:eye muscles
D:our eyes
E:computer use
F:eye move答案：E解析：文章第二段第一句便指出，过多的紫外线透过臭氧层是引起眼睛晶状体模糊的最大危险因素，并进一步分析了原因，故选B。
文章第三段的第一句便引出了本段的大意是关于夜盲症和眼疲劳，A项最为符合。
文章第五段首先陈述了儿童群体患近视的普遍性，然后论述引起儿童近视的原因，故选D。
文章第六段主要讲述了由于使用计算机而患夜盲症的人群群体比例，以及计算机是如何对人的眼睛产生伤害的，故选E。
由文章第二段第二句可知，夏季日光中过多的紫外线会增加角膜变形的危险，导致视力模糊并最终形成白内障，故选B。
文章第二段第三句中指出，这些紫外线只有通过防紫外线眼镜来防护以保护我们的眼睛，故选D。
由文章第四段可知，传统上，我们认为近视和远视是由遗传因素引起的，故选A。
由文章第六段第一句话可知，大约有25%的人群因为使用电脑而患有夜盲症，并且人群数量还有增加的趋势，故选E。 -

Baseline Exam Is Key to Eye Health
Even people with no signs or risk factors for eye disease can suffer vision loss and need to get baseline（基线）eye exams at age 40,says the American Academy of Ophthalmology(AAO)（美国眼科学会）.
The reminder（提示）is part of the AAO's EyeSmart campaign to mark Save Your Vision Month in February.
“Many eye diseases progress without any warning signs,”Dr. Stephanie Marioneaux,a clin-ical correspondent for the AAO,said in a prepared statement.“Gradual changes in vision can af-fect your ability to function independently and have confidence in your abilities.”
Based on the findings from the initial screening,an eye doctor will create a schedule for follow-up eye exams.
People of any age who have symptoms of eye disease or are at high risk due to family history, diabetes（糖尿病）or high blood pressure should consult with their eye doctor to determine how often they should have their eyes checked,the AAO recommends .By 2020,43 million Americans will be at significant risk for vision loss or blindness due to age-related eye diseases such as cata-racts（白内障）and glaucoma（青光眼）. That's a more than 50 percent increase over the current number of Americans with such vision-threatening diseases.
But many Americans are unconcerned about the risk of vision loss.Only 23 percent of Amer- icans are very concerned about losing their vision,while most feel weight gain or joint or back pain are greater worries than vision loss,according to an AAO survey conducted for its EyeSmart campaign.Gradual changes in vision can affect one's thought.
A: Right
B: Wrong
C: Not mentioned答案：C解析：题干句意：美国眼科学会认为人们在四十岁的时候需要做眼睛基线检查。根据文章首句“Even people with no signs or risk factors for eye disease can suffer vision loss and need to get baseline（基线）eye exams at age 40”可知即使没有患眼疾的征兆或风险，人们都有可能遭受失明，所以在四十岁的时候都需要做眼睛基线检查。
题干句意：Dr. Stephanie Marioneaux认为，眼疾的发展都有发病前兆。根据第三段他说的“Many eye diseases progress without any warning signs”可知，许多眼疾都没有发病前兆。故题干表述错误。
题干句意：视力的变化可以影响你的思想。根据第三段最后一句“Gradual changes in vision can affect your ability to function independently. ”可知视力的逐渐变化会影响你独立工作的能力，并没有将视力变化对思想的影响，故题干表述文中没有提及。
题干句意：根据视力初期筛选结果，眼科医生将建立一个视力定期复查时间表。in-itial screening意为“起始筛选，初期筛选”,follow-up意为“定期复查”。根据文章第四段可知题干表述正确。
题干句意：只有患糖尿病或者高血压的老人需要看眼科医生。根据第五段“People of any age… diabetes（糖尿病）or high blood pressure should consult with their eye doctor to determine how often they should have their eyes checked”可知任何年龄的人，只要有眼疾的症状或有家族遗传史，糖尿病或高血压的人都应该咨询眼科医生做眼部检查的频率。故题干表述错误。
题干句意：白内障和青光眼跟年龄有关。根据第六段“age-related eye diseases such as cataracts（白内障) and glaucoma（青光眼）”可知题干表述正确。
题干句意：大部分美国人更加关注失明的风险甚于关心增变胖或关节痛。根据最后一段“Only 23 percent of Americans are very concerned about losing their vision, while most feel weight gain or joint or back pain are greater worries than vision loss”可知，只有 23％的美国人关注失明的风险，大部分人认为变胖、关节痛或者背痛都比失明严重得多。故题干表述错误。 -
