题型描述: 阅读理解The family TV show Happy Days ran for 11 years from 1974 to 1984, creating several by-product series. In one episode (一集), there was a new character, an alien from outer space. He was played by an unknown actor. People roared with laughter at his crazy antics (滑稽动作). No one had seen this type of comedy before, and they protested for more. The network administrators knew they had a new star on their hands: from that single performance, Robin Williams became the star of a brand-new comedy series, Mork and Mindy. He played the character of an alien who comes to the Earth in a giant egg-shaped spacecraft. He is friendly, and observes and reports back to his planet. He sleeps standing on his head, thinks that all eggs are spacecraft, and sometimes wears his clothes backwards. His kind new friend, Mindy, helps to take care of him. They marry, and have a child together. But Mork gives birth, and the child is actually an old man who ages backward! In addition to his work as a comedian on this and other projects, Robin Williams is also an excellent dramatic actor.
