Man has invented four kinds of satellites.The first kind of satellites studies the geography of the earth.They are used to make maps.They also help countries to see where they may find oil or gold.
The second kind of satellites is used to guide ships and planes.A ship or a plane can send a message to the satellite,and the satellite can find out where the ship or the plane is.
The third kind of satellites studies the weather.These satellites watch clouds and strong winds moving across the earth.They warn countries to make preparation when very bad weather is coming.The last kind is used for communication.Telephone calls between countries can be sent by these satellites.Some can carry hundreds of calls at one time.The call is to be the satellite then the satellite sends it to a station in the country is being phoned,These satellites also carry pictures; they can send about eight programs at a time.

人们发明了四种类型的卫星.第一种卫星用于研究地球的地理环境.他们被用来画地图.他们还帮助国家找寻哪里有石油和黄金;
第二种是用来引导船与飞机,一艘船或一架飞机可以发送信息给卫星,然后卫星可以找到船或飞机的位置
第三种卫星研究天气这些卫星监视云朵和强风穿过地球.他们在坏天气来临前提提国家做好准备
最后一种用来交流国家间的电话是用这种卫星来传送的.一些可以同时承载上百个电话.首先电话传送到卫星上然后通过卫星传送到国家里的站点然后被接.这些卫星还可以承载图片,同时可以传输8种

人类已经发明了四种卫星。第一种卫星探测地球的地理状况，用来绘制地图。它们也帮助国家寻找开采石油或黄金的地方。
第二种卫星用来为轮船或飞机导航。轮船或飞机能向卫星发出信号，于是卫星就能找到它们所在的位置。第三种卫星研究气象。这些卫星观测地面上空经过的云和强风。当恶劣空气前来的时候，它们提醒国家做好准备。最后一种卫星用来通信。这些卫星可以在不同国家之间发送电话信号。有的卫星可以同时传递上百个电...

人类已经发明了四种卫星。第一种卫星探测地球的地理状况，用来绘制地图。它们也帮助国家寻找开采石油或黄金的地方。
第二种卫星用来为轮船或飞机导航。轮船或飞机能向卫星发出信号，于是卫星就能找到它们所在的位置。第三种卫星研究气象。这些卫星观测地面上空经过的云和强风。当恶劣空气前来的时候，它们提醒国家做好准备。最后一种卫星用来通信。这些卫星可以在不同国家之间发送电话信号。有的卫星可以同时传递上百个电话。电话传到卫星，然后卫星就能把它们传到电话所拨打的国家的一个地面站。这些卫星也能传输图像；它们能够一次发送大约八个节目。
