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. [br] According to the passage, which of the following is NOT true?
选项
A、We all know that we can’t exist without air.
B、Without air, we can’t hear anything.
C、Men have studied electricity in the air for centuries.
D、There’s huge energy in the air surrounding the earth.
答案
C
解析
是非判断题。本文主要解释了空气对于地球上生命的重要性。[A]、[B] 两项可以从文章的第一、二段找到依据,而[C]、[D]项则在最后一段。 其中[C]项与内容“But thorough(彻底的,深入的)study of electricity in the air was not possible until the development of radio”不符。所以答案 是[C]。
