The air surrounding us is important to everyone. Without air, we could not exist. Everyone understands that. But air is necessary in many other ways — ways that are not always so obvious or widely known.
If we did not have air, there would be no sound. Sound travels through air. Where there is no air, there is no sound. Without air there would be no fire. There would be no automobiles, since motors need air in order to operate.
Without air, there would be no wind or clouds. The night time would be very cold and the days very hot. We would be forced to seek shelter from the sun, as there would be no atmosphere to protect us from the sun’s deadly rays.
In this huge ocean of air surrounding the earth, there is more energy than in all the coal, oil and gas we have on the earth. Electrical energy is collected in the atmosphere as water is collected and stored in a dam (大坝). The existence of electricity in the air has been known for centuries. Men have gazed in wonder at the bright patterns of lightening in storm clouds. But thorough (彻底的,深入的) study of electricity in the air was not possible until the development of radio.
Without air protection, the sun’s rays ______.
选项
A、will become very cold
B、will do good to human beings
C、will become hot
D、will do harm to human beings
答案
D
解析
本题考查文中的细节。根据文章第三段最后一句“‘We would be forced to seek shelter from the sun,as there would be no atmosphere to protect us from the sun’s deadly rays”.可以判断答案为[D]。其中理解deadly 也是个关键,它的意思是“致命的”,可以得知Without air protection, the sun’s rays will do harm to human beings(如果没有空气的保护,太阳 光线会伤害我们)。
