解答 AEGDF
36.A 細節(jié)題.根據(jù)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,雖然該詞普遍被叫做"雪盲",但是在沒有雪的地方也會發(fā)生,故選A.
37.E 細節(jié)題.根據(jù)上一句的介紹The terms"snowblind"and"snow blindness"have become popular because snow is highly reflective of ultraviolet radiation可知,這個術語很流行,因為雪能高度反射紫外線,所以snow can reflect over 80percent of the UV rays that fall upon it這句話說雪能反射80%的紫外線,起到承上啟下的作用,故選E.
38.G 上下文語境.根據(jù)后一句話Anderson Cooper experienced snow-free snow blindness first-hand a few years ago 可知,這位記者在沒有雪的地方也經(jīng)歷了"雪盲",可見,水和白沙也有反射紫外線,增加了這種風險,故選G.
39.D 細節(jié)題.從句sun lamps can cause temporary"snow"blindness if proper eye protection is not used.
可知,太陽燈也能造成暫時的"雪盲",推出一些人造的東西也能反射紫外線,故選D.
40.F 概括題.根據(jù)這段的內容介紹可知,主要介紹了幾種減少"雪盲"發(fā)生的方法,故選F.
點評 選句填空應先通讀全文,再結合空白處的前后文暗示,選出正確答案.
