B

Many people catch a cold in the springtime or fall. It makes us wonder. If scientists can send a man to the moon, why can’t they find a way to deal with 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 brings congestion（拥塞）in it. That is to say, you cannot breathe well. As a result, you feel terrible. However, your body is actually “eating” the virus. Your temperature rises and you get a fever, but the heat of your body is also killing the virus. Besides, you have a runny nose to stop the virus from getting into you. You may feel terrible, but in fact your wonderful body is doing everything it can to kill the cold.

Different people have different ways to deal with common colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people take hot baths; some drink warm water, milk, or things like that; other people take medicine to stop the fever, congestion, and runny nose.

Some scientists suggest you should not take medicine when having a common cold, saying that it is bad for you to do that. If you take medicine, your body will stop reacting to the virus and thus won’t have a way to fight it and kill it, which makes the virus stay in you longer. Bodies can do an amazing job on their own.
