The days are getting shorter and shorter, and temperatures are dropping. Winter is coming and it is easy for people to catch flu. Many people have started taking vitamin C pills as a precautionary(预防的)way. But a research has shown that vitamin C pills do not provide as much protection as they think. They are even not as good as other ways, like often washing your hands. Some German scientists have given people information and a test on the subject helping to stop incorrect ways.

Whether it is caused by cold or flu(流行性感冒), a runny nose and sore throat are signs of catching a cold. Many people overestimate(高估) the advantages of vitamin C and other pills. For years it was believed that taking vitamin C pills not only provided protection against colds but also against cancers, helping people to live longer. But the result of the research showed disagreement on these beliefs(看法). The result has now come out on the website wwww.informedhealthonline.org. “Some pills may not help people live longer. Some pills may even lead to earlier death,” says Professor Peter Sawicki. Scientists also say that the best way to get vitamins is through food instead of having vitamin pills. That is to say, we disagree with the way of taking vitamin C pills.

There are many simple but useful ways to lower the risk of catching a cold. These include often washing your hands with normal soap(肥皂) and water and not touching your face with your hands. People who have already had a cold can stop it from spreading by throwing away tissues(纸巾) at once after using them and not shaking hands with other people.

A rabbit is running into his hole. You may ask, “What happened?”
Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they ran, too. They know there is danger. The rabbit has told them something without making a sound. It has given them a signal.
Many other animals use this kind of language. When a bee finds some food, it goes back to his home. It can’t tell the other bees where the food is by speaking to them, but it does dance in the air. This tells the bees where the food is.
But animals say things by making sounds. A dog barks, for examples, when a stranger comes near. A cat purrs(发出呼噜呼噜的声音) when pleased. Some birds make several different sounds, each with its own meaning.
But human beings have something that no animals have---- a large number of words about things, actions, feelings or ideas. We are able to give each other information to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things that have happened, or send messages to people far away. No animals can do this. No animals has the wonderful power of language.
No one knows how man learned to make words. Somehow he learned to make them. As centuries went by, he made more and more new words. This is what we mean by language.
People in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for examples, contains four or five hundred thousand words. But we don’t know all these. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we met a new word, look it up in the dictionary. A dictionary is the most useful book.
