分析 "雪盲"是一种很可怕的现象,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.
解答 AEGDF
36.A 细节题.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,虽然该词普遍被叫做"雪盲",但是在没有雪的地方也会发生,故选A.
37.E 细节题.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 80percent 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.
38.G 上下文语境.根据后一句话Anderson Cooper experienced snow-free snow blindness first-hand a few years ago 可知,这位记者在没有雪的地方也经历了"雪盲",可见,水和白沙也有反射紫外线,增加了这种风险,故选G.
39.D 细节题.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.
40.F 概括题.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.
点评 选句填空应先通读全文,再结合空白处的前后文暗示,选出正确答案.
