Many people believe the glare from snow causes snowblindness.Yet,dark glasses or not,they find themselves suffering from headaches and watering eyes,and even snowblindness,when exposed to several hours of “snow light”.
The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country.Rather,a man’s eyes frequently find thing to focus on in a broad expanse of barren(荒芜) snow-covered area.So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to lock at.Finding nothing,hour after hour,the eyes never stop searching and the eyeballs become sore and the eye muscle aches.Nature balances this irritation(刺激) by producing more and more fluid which covers the eyeball.The fluid covers the eyeball in increasing quantity until vision blurs(模糊),then is obscured（看不清）and the result is total,even though temporary(暂时),snowblindness.
Experiments led the Army to a simple method of overcoming this problem.Scouts（军队） ahead of a main body of troops are trained to shake snow from evergreen bushes,creating a dotted line as they cross completely snow-covered landscape.Even the scouts themselves throw lightweight,dark colored objects ahead on which they too can focus.The men following can then see something.Their gaze is arrested .Their eyes focus on a bush and having found something to see,stop scouring（搜寻 ） the snowblanketed landscape.By focusing their attention on one object at a time.The men can cross the problem of crossing a continuous white land.

许多人认为长时间盯看雪地会导致雪盲.但是,无论你是否佩戴墨镜,只要连续数小时露在刺眼的白光中,人们都会出现头痛和流泪的症状,甚至患上雪盲症.
美国军方近日通过一支在雪地覆盖的国家行军的队伍证明,长时间看着雪地并不会导致雪盲.其实,由于人长时间把眼光集中在荒芜的,冰雪覆盖的地区时,他的眼睛会在视线范围内来回搜寻些什么东西作为目标物盯视.当长达几小时不停地搜寻却毫无收获时,眼球会累,眼部肌肉酸痛.我们身体的自然机能对抗这种刺激的方法是产生越来越多的液体浸泡眼球.当越来越多的液体覆盖眼球的时候,视线变得模糊,于是人们就会看不清楚,结果就是——即使那是暂时性的症状——雪盲.
这个实验使美国军队找到了对抗雪盲的方法.当军队经过一片冰雪覆盖的地区时,他们派出一些受过训练的先锋部队把常青树上的雪摇落下来,创造出一条点带.这些先锋部队甚至会在他们前方的雪地上扔下一些轻型的深色的物体好让他们自己也有些什么东西作为目标物.后面的大部队因此就能看到些什么东西,目光就被锁定在那些地方因而就不用在这片雪地上搜寻些什么东西了.依靠把军队的目标定格在一个又一个这些目标物上,雪盲的问题就得到了解决,军队得以在一片茫茫的雪原中前进.
话说楼主要别人人工翻译那么一大篇东西还没有悬赏分真的很欠砍!人工翻译那么一篇东西是需要时间和精力的好吗?那起码的诚意还是要有的!想要别人付出劳动力自己又不付出任何代价,那也太不公平了!如果我不是要找些什么东西保持英语语感,我的反应肯定也会像一楼二楼那样!
另：楼主这片该不会是高考阅读题吧?我清楚的记得我高三的时候做过一篇这样的阅读（或者完填?）...
