　　After watching, let the students discuss the questions for a while. Get them to give the explanations in English.

　　For instance: A satellite goes round the earth. The moon is a satellite of the earth. There are many man-made satellites in the space too. Then explain that man-made is an adjective meaning made by people. “Man” in this text means “the human race”.
