READ. UFOs are strange flying objects that some people report they have seen in the sky and believed to be spacecraft from another planet. Many scientists do not believe so. They say that if people see a UFO, it might be an aircraft, a weather balloon or meteor. However, there is still evidence for people to believe in the existence of UFOs. In 1947, Kenneth Arnold, an experienced pilot in the USA, reported that he saw nine large round objects traveling at about 2, 800 meters an hour to the left and north of Mount Rainier. In 1952, there were more than 1,500 UFO sightings around the world. In 1954, a woman and her children believed they saw a UFO above their house. The woman said she saw two aliens in the spacecraft. In 1964, a farmer claimed he saw an egg-shaped object in one of his fields and also aliens collecting soil samples. In 1971, two men claimed they were captured by aliens and taken abroad a spacecraft. After being examined by the aliens, the men were free. In 1978, a young pilot and his plane disappeared after sighting a UFO. In 1981, Renato Nicolai, who was living in the south east of France, reported that he saw a plate-like device at a treetop 30 meters away from his garden. * Find the words in the text having the following meanings.  21. proof, support ……………………………  22. falling star, or shooting star ……………………………  23. unknown / strange people or things ……………………………  24. bringing together or gathering ……………………………  25. caught as a prisoner ……………………………  26. became impossible to see ……………………………  ** Complete the notes. 27. …………………………………………………… or …………………can be mistaken for an alien spacecraft. 28.
