 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.

A.to clear the vision

D.to produce more and more liquid小题3: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

One day last September, as Britney Spears was about to board a flight to Los Angeles from London, a blue bottle fell out of her purse. She quickly put it back in, but not before the camera recorded the event. Neither Spears nor her spokesman was willing to comment on the contents of the bottle, but the next morning London’s Daily Express published a page of pictures under the headline “EXCLUSIVE: POP PRINCESS SPOTTED AT AIRPORT WITH POT OF SLIMMING TABLETS.” Spears was apparently carrying Zantrex-3, one of the most popular weight-loss pills now sold in the United States. The pill, which is sold at about fifty dollars for a month’s supply, contains a huge amount of caffeine, some green tea, and three common South American herbs that also act as stimulants (兴奋剂). It hit the U.S. market last March and has had a success that would be hard to overstate. Millions of bottles have been sold, and during the Christmas season it was displayed in the windows of the nation’s largest chain of vitamin shops, G.N.C. (It is so highly sought after that many of the stores keep it in locked counters.) Zantrex-3 is also sold at CVS, RiteAid, Wal-Mart, and other chains, and over the telephone and on the Internet. If you type “Zantrex” into Google, more than a hundred thousand pieces of information about it will appear. At any moment, there are scores of people sell it on eBay.

Perhaps the most interesting thing about the success story of Zantrex-3, however, is that it is far from unique. There are hundreds of similar products on the market today, and they are bought by millions of Americans. And though Zantrex’s producer makes some exciting statements (“the most advanced weight control compound (化合物)period”), so do the people who sell Stacker 2 and Anorex along with those who sell Carb Eliminator and Fat Eliminator. Almost all of these compounds suggest that they can help people lose weight and regain lost energy, and often without diet, exercise, or any other effort.

A. it is difficult to say how successful Zantrex-3 is

B. you can’t overstate the success of Zantrex-3

C. you can’t think too highly of the success of Zantrex-3
