Background Information (1) Art Buchwald (1925- ) He is a well-known American humor columnist for Washington Post. His columns frequently deal with stories about politicians and famous personalities, current events in politics and issues in the news. (2) Manhattan Manhattan is in New York City. It’s one of the commercial, financial and cultural centers of New York City. It has many famous landmarks and tourist attractions. They include Broadway, Chinatown, the Empire State Building, Greenwich Village, Times Square, the United Nations Headquarters, Wall Street, etc. (3) Venus It is the nearest planet to the earth in the solar system. Besides the sun and the moon, Venus is the brightest object in the sky. It is called the “morning star” in the east at sunrise, and “the evening star” in the west at sunset. The average temperature is about 47.5 degrees centigrade. Oxygen is rare there. 95% of its atmosphere is carbon dioxide. It is satirically interesting that Art Buchwald has chosen the planet Venus as the

We human beings tend to take pride in our "mastery"of nature.We've viewed ourselves as"conqueror"of the skies and oceans.We've devised ways of using the natural resources of the earth for great profits.In recent years,however,we've begun to realize that we are not masters of the natural world,but a part of it.We've also begun to understand that if we don't treat the world with great respect,our very existence as a species may be threatened.And Art Buchwald is just issuing such a wamning in his seemingly humorous article. Step2.Global Reading 1.True or false questions (1)The planet of Venus was filled with excitement because scientists had managed to land a satellite on the planet Earth. (2)The satellite hasn't sent back any information since it landed on Earth. (3)The Venusian scientists were concemed about the feasibility ofa manned flying saucer landing on Earth.

Introductory Remarks “Is There Life on Earth?” is an essay written by Art Buchwald, a well-known American columnist. He has meant this article to appear as a piece of science fiction or to be an amusing nonsense story just for light reading.
