Question

Snowblind--it’s a frightening word. Thankfully, it’s a condition that is totally preventable.

Snow blindness is a painful, temporary loss of vision due to overexposure to the sun's UV rays. Essentially, snow blindness is caused by a sunburned eye.

1.Though it is commonly called snow blindness, the condition can (and often does) occur in the absence of snow.

The terms "snowblind" and "snow blindness" have become popular because snow is highly reflective of ultraviolet radiation. 2.Also, skiing, mountain climbing and snowboarding usually take place at relatively high altitudes, where the sun's UV rays are stronger. Combined, these factors can double your risk of getting sunburned eyes, compared with being outdoors at lower altitudes in the summertime.

3.Television journalist Anderson Cooper experienced snow-free snow blindness first-hand a few years ago when he spent a couple hours on a boat in Portugal without sunglasses and ended up "blind for 36 hours," according to his report of the incident.

Not only can you become snowblind without snow-- it can happen without sunlight, too! 4.For example, sun lamps can cause temporary "snow" blindness if proper eye protection is not used.

5.To relieve pain or discomfort from snow blindness, stay indoors and wear sunglasses. Keep your eyes well-moistened with artificial tears. For additional relief, use over-the-counter pain relievers. Be sure to use only pain relievers you know you can take without worry of an allergic reaction. You also may find that placing a cool, dampened washcloth over your closed eyelids is comforting.

A. You don't need snow to become snowblind

B. It will likely affect those traveling in snowy conditions

C. To prevent snow blindness on the slopes, wear sunglasses

D. Sometimes it occurs from man-made sources of ultraviolet radiation

E. In fact, snow can reflect over 80 percent of the UV rays that fall upon it

F. Snow blindness is scary, but usually it's temporary, and there are ways to relieve the discomfort

G. But water and white sand also are highly reflective of the sun's UV rays, thus increasing the risk

【解析】

“雪盲”是一种很可怕的事情，在没有雪的情况下也会发生，文章介绍了几种可以预防“雪盲”发生的方法。

1.A

根据后面的句子Though it is commonly called snow blindness, the condition can (and often does) occur in the absence of snow.可知，虽然这词被叫做“雪盲”，但是在没有雪的地方也会发生。故选A。

2.E

根据上一句的介绍The terms "snowblind" and "snow blindness" have become popular because snow is highly reflective of ultraviolet radiation.可知，这个术语很流行，因为雪能高度反射紫外线，所以snow can reflect over 80 percent of the UV rays that fall upon it.这句话说雪能反射80%的紫外线，起到承上启下的作用，故选E。

3.G

上下文语境，根据后一句话Television journalist Anderson Cooper experienced snow-free snow blindness first-hand a few years ago可知，作者在没有雪的地方也经历了“雪盲”，可见，水和白沙也会反射紫外线，增加了这种风险，故选G。

4.D

从句sun lamps can cause temporary "snow" blindness if proper eye protection is not used.可知，太阳灯也能造成暂时的“雪盲”，推出一些人造的东西也能反射紫外线，故选D。

5.F

概括题，此空位于段首，根据这段的内容介绍可知，主要介绍了几种减少“雪盲”发生的方法，故选F。
