   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.

These are therefore controlled in such a way that they are 【C10】______ turned toward the Sun. [br] 【C3】
选项
答案 D
解析 空格位于不定冠词a和形容词different后，故空格填入单数名词。下文提到了各种用途的人造卫星，由此推知此处讲被发射升空的人造卫星有不同的用途，function“功能”符合语义，故选D。realm指“(活动、兴趣、思想的)领域”，无法表达“用途、功能”的含义，故排除。
