Passage A
Many people catch cold in the spring time or fall.It makes us wonder if scientists can send a man to the moon,why can't they find a cure for the common cold?The answer is easy.There are actually hundreds of kinds of cold viruses out there.You never know which one you will get,so there isn't a cure for each one.
When a virus attacks your body,your body works hard to get rid of it.Blood rushes to your nose and causes a blockage(堵塞)in it.You feel terrible because you can't breathe well,but your body is actually"eating"the virus.Your temperature rises and you get a fever,but the heat of your body is killing the virus.You also have a runny nose to stop the virus from getting to your cells.You may feel miserable,but actually your wonderful body is doing everything it can to kill the cold.
Different people have different remedies for colds.In the United States and some other countries,for example,people might eat chicken soup to feel better.Some people take hot baths and drink warm liquids.Other people take medicines to relieve various symptoms(癥狀)of colds.
There is one interesting thing to note.Some scientists say that taking medicines when you have a cold is actually bad for you.The virus stays in you longer because your body doesn't develop way to fight it and kill it.

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!
