I. Read the passage and decide whether the statements are TRUE (T) or FALSE (F).
The word alien is a popular word for an extraterrestrial life-form, or a being from another planet. No one knows whether there is life elsewhere in the universe. But some scientists think that it is possible.
Whether life exists on other planets or not, the idea of aliens has excited people for years. Lots of people enjoy science fiction stories about aliens - also called extraterrestrials. Some believe that aliens actually have visited Earth. Many people have reported seeing unusual objects in the sky. Some think that these UFOs are alien spaceships. The presence of aliens on Earth has never been proven, however.
Most scientists believe that for another planet to have life on it, it must be similar to Earth in several ways. It is likely to need an atmosphere and water. It also must orbit a star, like the Sun, at a good distance. This star would provide the right amount of light and heat for life to exist.
Scientists have studied planets and moons in our Solar System to see if they can support life. Space probes have searched for traces of bacteria or other tiny living things on Mars. Some scientists are also looking for the possibility of life outside our Solar System. Using radio telescopes, they hope to capture signals from intelligent aliens.
So far, no evidence of extraterrestrial life has been found. However, scientists have discovered hundreds of planets that orbit distant stars. Some of these planets are an ideal distance from their stars, and some are roughly the size of Earth. It may be possible that life has developed on one or more of them.
1. ____ No one knows for sure that there is life on other planets, excluding scientists.
2. ____ There is actually no extraterrestrial life-form in the universe.
3. ____ Both “aliens” and “extraterrestrials” refer to life existing on other planets.
4. ____ Many people have seen UFOs but they couldn’t prove that the UFOs are connected to aliens.
5. ____ To support life a planet needs to have an atmosphere and water and provides an amount of light and heat.
6. ____ Only the telescopes are able to search for traces of living things in space.
7. ____ Scientists haven’t found any traces of extraterrestrial life on the moons in the Solar System.
8. ____ Scientists still can’t find any planets which are roughly the size of Earth.
