Today our knowledge of food and what it does for our bodies is far more advanced than that of the old times.Now we know about vitamins and how each kind of vitamin helps in the growth of a particular part of our body.There are on the market all kinds of vitamins which one can take to make up for one's lack of certain important things that are needed for good health.Of course，if we eat well and properly，the food we eat will take care of our body and so there is no need to take any kind of vitamins unless our doctor tells us that our bodies are short of something that can be supplied by them.
Generally speaking，everything we eat does some good to our body，but if we eat too much of one kind of food and pay too little attention to others，we may have too much of one kind and not enough of others.Then we may be in trouble.
We are often told that we must eat some meat at each meal in order to get the necessary proteins.That is only partly true，for proteins are not found only in meat.We can also get them from some vegetables.The best advice about what to eat is that we should cat all kinds of food but never too much.

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！
