Many people believe the glare from snow causes snow-blindness. Yet, 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 United States 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 and fluid which covers the eyeball. The fluid
covers the eyeball in increasing quantity until vision blurs,then is observed, 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.
A suitable title for this passage would be_________.A. snow-blindness and how to overcome it
B. nature's cure for snow blindness
C. soldiers in the snow
D. snow vision

单选题Passage1 Questions 1 to 5 are based on the following passage. It's interesting that the arrival of snow has the effect on people in different countries.(76) For some countries it is an important happening to celebrate each year, while for others a catastrophe （灾害） or even a wonder. But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year.Britain is one of them, for which the arrival of snow quite simply creates problems.Within hours of the first snowfalls, however light, roads are blocked; trains and buses have to stop in the middle of the way.Normal communications are affected as well: telephone calls become difficult and the post immediately takes more time than usual.And almost within hours there are also certain shortages-bread, vegetables and other things-not because all these things can no longer be produced or sent to shops,but mainly because people are frightened and go out and store up with food and so on...just for fear that something bad should happen. But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don't have such problems.It is simply because there is not enough planning and preparation.We need money to buy equipment to deal with snow and ice.To keep the roads clear, for example,requires snow-ploughs (扫雪机) and machines to spread salt.(77) The reason why a country like Britain does not buy snow-ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education, helping the old, and so on.3 After a few hours' snowing there are often some shortages of food because______.A
shops have closed downB
people buy as much as they canC
farmers can produce no moreD
people eat more vegetables
