就是这篇了“Through repeated experiments,now the army researchers have found a simple method of overcoming this problem of snow-blindness.Scouts ahead of the main body of troops are trained to shake snow off from evergreen bushes,and create some eye-catching marks on the snow-covered ground as they cross the wilderness completely covered with snow.To protect their own eyes from snow glare,the scouts themselves also throw some light-weight dark colored objects on the snow ahead so that their,too,can focus on these things.The men following them can always have something to look at.Their gaze is then arrested form time to time by a bush or some mark left by the scouts ahead.In that case,the eye will stop searching the snow-blanketed wilderness.By focusing their attention on something at a time,the soldiers can cross the snow without suffering snow-blindness.In this way,the problem of crossing snow-covered wilderness is overcome.”
