　　Many people believe the glare from snow causes snow blindness. Yet, wearing dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snow blindness, when exposed to several hours of “snow light”.

　　The Canadian army has now determined that glare from snow does not cause snow blindness in troops in a snowcovered country. Rather, a man’s eyes frequently find nothing to focus on in a broad expanse of barren snowcovered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation by producing more fluid which covers the eyeball. The fluid covers the eyeball in increasing quantity until vision blurs, and then is obscured, and the result is total, even though temporary, snow blindness.

　　Experiments led the army to a simple method of overcoming this problem. Scouts, 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 the snowblanketed landscape. By focusing their attention on one object at a time, the men can cross the snow without becoming hopelessly snow blind or lost. In this way the problem of crossing a solid white terrain is overcome.

 

　　問題：

　　1.To prevent headaches, watering eyes and blindness caused by the glare from snow, dark glasses are ____.

　　A.indispensable

　　B.ineffective

　　C.useful

　　D.available

 

　　【參考答案】B

　?。劭键c］推理判斷題

　　【精析】B 根據(jù)第一段第二句“…wearing dark glasses or not, they find themselves suffering from headaches and watering eyes, and even snow blindness, when exposed to several hours of ‘snow light’.”可知，戴不戴墨鏡都會產(chǎn)生“雪盲”的癥狀，如頭疼、眼睛流淚等。由此可推知，在這種情況下，墨鏡并不起什么作用。indispensable:必需的，不可或缺的；ineffective:無效果的，不起作用的；useful:有用的；available:可用的，可獲得的。故選B。
 

　　2. When the eyes ache, tears are produced to____ .

　　A.loosen the muscles

　　B.remedy snow blindness

　　C.clear the vision

　　D.ease the irritation

 

　　【參考答案】D

　?。劭键c］事實細節(jié)題

　　【精析】D 根據(jù)第二段第五句“Nature offsets this irritation by producing more fluid which covers the eyeball.”可知，眼淚的產(chǎn)生是為了緩解刺激。故選D。
