Sputnik 1 was the first artificial satellite. It can be described as an aluminum 【C1】______ with a diameter of 58 centimeters and weighing 83.6 kilograms, equipped with instruments to measure the temperature and the 【C2】______ of the atmosphere. Sputnik 1 was launched into orbit around the Earth by the former Soviet Union on 4 October 1957. Since then, hundreds of artificial satellites have been launched, each with a different 【C3】______.
Some artificial satellites are used for telecommunication, which enable us to make telephone calls to any part of the world, to see 【C4】______ television transmissions and to communicate via the Internet. Other artificial satellites are used for navigation, so that people on Earth can know at any moment the position of an object, within a few meters. Others are weather or meteorological (气象的)satellites, launched to 【C5】______the state of the atmosphere and to follow the movement of the clouds as they gather. There are also military satellites, for the purpose of 【C6】______information on the armaments and the troops in countries which may be 【C7】______ and also to indicate the launch of a missile.
Each satellite has its own orbit which is 【C8】______ according to its purpose. Communications satellites, for example, have a geostationary orbit. That is an orbit which turns at the same speed as the 【C9】______ of the Earth. Satellites used for weather forecasting pass over the two poles of the Earth. By so doing, a different part of the Earth surface is viewed on each successive orbit. All artificial satellites get the energy they need by huge solar panels which extend like wings. These are therefore controlled in such a way that they are 【C10】______ turned toward the Sun. [br] 【C10】
选项
答案
A
解析
空格所在的由that引导的定语从句主要句子成分完整,可推断空格处填入副词。上一句提到“所有人造卫星都靠巨大的、仿佛翅膀一样展开的太阳能电池板(by huge solar panels)获得能量”,由此推测人造卫星被控制成总是面向太阳,故选A。never“从不”为反向干扰,若人造卫星不朝向太阳,则无动力续航,不符合逻辑,故排除。
