Are your eyes dry,watery,seeing double or (31)___ to light,and do your back and neck ache?If so,you are likely one of many people today who suffer from digital eyestrain(视疲劳)also called computer-vision syndrome.
Eyestrain is often related to the amount of (32)___to screens,the distance from eyes to screens and the use of multiple screens at the same time.However,studies
have also shown that the blue light produced by digital devices reaches further into the eyes than other kinds of light.This light actually assisis attention during the day but can result in (33)___ sleep patterns at night.
Scientists have stated that eyestrain is not a necessary evil,even in a modern world that circles around technology.Sometimes (34)___some simple details about your relative position to screens,such as slaying about 60 centimeters away,will help.Also,avoid overhead and other direct sources of light,and use (35)___ lamps and window blinds while looking at digital devices instead.
Beyond the ways that you relate to digital screens,there are also ways to change how you view screens that are helpful in (36)___ eyestrain.To begin with,your computer screen should be high-resolution (高分辨率),and may require a screen to decrease(37)___.Also,be aware that''computer glasses,"which cut down glare(刺眼的光} and blue light,are (38)___ on the markect.
Finally,many of us fall into bad habits while usiug digital screens that only(39)___ the effects of eyestrain.When viewing digital screens,many people blink (眨眼) one third less often than they usually do.Place a reminder on your computer to"blink!"so that your eyes don't dry out.Also,(40)___ your eyes'focusing muscles by using the 20-20-20rule:every 20minutes,focus on something 20 feet away for 20 seconds.
There are many other methods used to help relieve eyestrain,so find what works for you rather than giving in to tired vision.

答案和解析
31-40 E C J A H K I B D G
31.E 考查形容词.根据前面的 eyes dry,watery,seeing double 可知,这些都是computer-vision syndrome症状,所以be sensitive to light意思是对光敏感也是表现之一.
32.C 考查名词.句意为 digital eyestrain和长期眼睛暴露在电脑屏幕前有关系.exposure to暴露于…
33.J 考查非谓语.此处interrupted是过去分词形式做定语,修饰sleep patterns,表示被动,意思是被扰乱的睡眠模式.
