Tourism has begun in Antarctica in the 1950 s.It's reported that about 40，000 tourists are about to visit it this season.However，people hold different views on whether humans should be allowed to land on this continent.
Some scientists are worried about the problems that tourists might cause to Antarctica.The environment might be destroyed，because tourists leave footprints and they all go to the same places--the coastline，which is also where animals in Antarctica live.
However，some people believe that if carefully controlled，tourism can be good for Antarctica.Tourists to the icy continent might be ready to support the protection of it，and possibly they will take part in the discussion about global warming，which has led to the melting of the ice in Antarctica.
Many researchers of Antarctica put forward that tourists should follow some rules.For example，they should not eat or smoke there.Nothing should be taken as a souvenir （紀(jì)念品） and nothing should be left behind.Tourists who are lucky enough to visit the Antarctic should keep it well so that future generations will also be able to enjoy such fantastic views.

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？
At this stage（階段） we still cannot be sure.All the planets，except the Moon and Mars，are so far away that it will take hundreds of years for spaceships to reach them！
