【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Snow falls in the Earth’s extreme North and South throughout the year. However, the heaviest snowfalls have been reported in the mountains of other areas during winter. Snow is even known to fall near the Equator (赤道), but only on the highest mountains.

Snow contains much less water than rain, but much of the water the world uses comes from snow. 【1】 In the western United States, mountain snow provides up to seventy-five percent of all surface water supplies.

Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. 【2】 The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snow’s surface will help to send back sound waves.

【3】 It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. 【4】 .

People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. 【5】 .

A. These include food, emergency medical supplies, and extra clothing to stay warm and dry.

B. Snow also influences the movement of sound waves.

C. Melting snow provides water for rivers, electric power stations and agricultural crops.

D. Mountain snowfall is heavier than that in the South and the North Poles.

E. In many places, streets were blocked; houses fell down and supplies were short.

F. Others die from heart attacks caused by too much physical activity out in the cold.

G. Snow may be beautiful, but it can be deadly.

试题分析:

【1】C 考查对上下文语境的理解。空前的意思是：世界上使用的大部分水来自于雪，这里选C（融化的雪为河流，电能站及农作物提供水。）与上下文一致。

【2】B考查对上下文语境的理解。空后的意思是：雪的表面吸收光波，所以这里选B（雪也影响光波的运动。）与上下文一致。

【3】G 考查对上下文语境的理解。空后的意思是：它应对数以百计的人的死负责任，很多人死于冰雪路面的交通事故，所以这里选G（ 雪或许很美丽，但是也是致命的。）与上下文一致。

【4】F考查对上下文语境的理解。 空前的意思是：很多人死于冰雪路面的交通事故或被困在冬季的暴风雨中。所以这里选F（其他一些死于寒冷天气太多户外活动引发的心脏病。）与上下文一致。

【5】A考查对上下文语境的理解。空前的意思是：住在这些地方的人们应该在车上带上应急物资。所以这里选A（这些包括食物，急救医疗用品以及一些衣服来保暖及防湿。）与上下文一致。
