Many people believe the glare（炫目的光）from snow causes snowblindness. Yet, with 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 nothing to focus on （聚集） in a broad space of snow- covered without- grass land. So his gaze continually moves and jumps back and forth over the entire landscape in search of something to look at. Finding something, hour after hour, the eyes never stop searching and the eyeballs become tired and the eye muscles ache. Nature makes up for this discomfort by producing more and more fluid （流体） which covers the eyeball. The fluid covers the eyeball in increasing quantity until it makes eyes difficult to see dearly, and the result is total, even though for a short time, snowblindness.
Experiments led the Army to a simple method of overcoming this problem. Scouts（侦察兵）ahead of the 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 can focus too. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching the snow -blanketed landscape. By focusing their attention on one object at a time. the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a continuous white land is overcome.

72．To prevent snowblindness caused by the strong light from snow, wearing glasses or not ________.
A. depends on whether the snow is white enough
B. makes no difference
C. makes much difference
D. depends on whether the snow is thick
73．When the eyes are tired, tears flow out ________.
A. to clear the vision
B. to make the eyes stop searching
C. to make the vision unclear
D. to produce more and more liquid
74．Snowblindness can be avoided ________.
A. by moving one’s gaze back and forth
B. by walking ahead and keeping looking around
C. by making up for the discomfort of one’s eyes
D. by providing the eyes with something to focus on
75．What is the probable meaning of the underlined part “Their gaze is arrested” （in paragraph 3 ） ?
A. They get something to look at.
B. They can only look at one spot.
C. Their eyes are clear.
D. They can’t see freely.

On Jan. 13th, 2009, the Peanut Corporation of America issued a recall (召回) for products it had made over the past six months, after five people had died and more than 400 had fallen ill with salmonella（沙门氏菌）poisoning as a result of contamination. Two weeks later, the recall was extended to more than 400 consumer products made since Jan. 1, 2007, including Jenny Craig nutritional bars and Keebler Peanut Butter Sandwich Crackers, while the toll from the contamination had reached eight dead and more than 500 sickened in 43 states, half of them children.
The company's factory in Blakely, Ga., which was the source of the contamination, supplied some of the largest food makers in the nation. The outbreak showed the complexities of the industrial food chain, and left consumers to figure out if some food in their cabinets had a danger. The recall of peanut products is the latest in a series of increasingly severe food contamination scares involving tomatoes, spinach, cantaloupes and other foods.
The Georgia plant, which is closed, packed peanut butter in bulk ranging from 5 to 1,700 pounds, much of which was shipped to institutions. Many school districts have pulled peanut butter from menus, with some substituting more commonly recognized supermarket brands. New York City school officials said they had not bought any peanut butter or products with ingredients that originated at the Georgia plant.
An F.D.A. inspection team that visited the plant on Jan. 9 discovered that on 12 occasions in 2007 and 2008 tests conducted by the company found salmonella contamination in its products but that it shipped the contaminated products to customers after a retest found no contamination and did nothing to clean the plant.
