1.Passage A
Many of us have read stories or seen films about space-creatures.They come to Earth in spaceships that look like flying saucer(飛碟).These space-creatures do not look like human beings at all,but they are usually very intelligent(聰明).In one film,they were tiny little men with large heads.When they landed on Earth,they knew exactly what to do.They went straight to the President's palace and made him their prisoner!
The stories about space-creatures are,of course,not true.Space-Creatures exist only in story-books and in films,just like giants(巨人) and fairies.
But many scientists are asking this question.Is there life on other planets?There are millions of planets in the Universe,and Earth is just one of them.Human beings have lived on Earth for thousands of years.Could there be living things on other planets too?Many people believe that the other planets in the Universe are not suitable for living things.They are either too hot or too cold.Some of them have poisonous gases on them that will kill any living thing.
Are scientists sure that there is no life on other planets?
