第三部分:阅读理解(共20小题;每小题2分,满分40分)
阅读下列短文, 从每题所给的四个选项中,选出最佳选项,并在答题卡上将该项涂黑。
For thousands of years, people have seen things they didn’t understand in the sky. The United States Air Force first used the words “Unidentified Flying Object” to describe them. Today everyone uses the term UFO. When people see a UFO, it is usually no more than a weather balloon or an airplane. But the Center for UFO Studies goes on to receive hundreds of reports each year.
In 1947 a businessman and pilot, Kenneth Arnold, was flying near Mount Rainier, Washington when he saw nine shiny, round objects flying through the air. He told a newspaper reporter they looked like “pie plates skipping over water.” The reporter used the words “flying saucer（碟子）” in his story and today that is the popular name for UFOs.
The Center for UFO Studies lists three kinds of contacts with flying saucers. “Encounters（遭遇）of the first kind” are reports of unknown objects or lights in the sky. People have “Encounters of the second kind” when a UFO leaves burn marks or other signs on the ground. People report “Close encounters of the third kind” when they see aliens in or near a UFO.
