It is easy for many people to 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 cure (治疗) for the common cold? The answer is easy. There are actually different cold viruses (病毒) out there. （1）You never know which one you will get, so there isn't a cure for each one.

    When a virus attacks (攻击) your body, your body works hard to get rid of (消除) it. You may feel very uncomfortable,（2）but your wonderful body is doing what it can do to kill the cold. You may have a runny nose to stop the virus from getting into your cells (细胞).Your temperature goes up and you get a fever, but the heat of your body is eating the virus.

    （3）不同的人做不同的事情来应对感冒。In the United States and some other countries, for example, people might have chicken soup to help them to cure the cold. Some people take hot baths and drink warm water. Other people take medicine to stop different symptoms(症状)of colds.

    There is one interesting thing to note. （4）some scientists say taking medicine when you have a cold is bad for you. The virus stays in you longer because your body doesn't have a way to fight it and kill it. Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. （5）如果你不吃药，你得花一周来消除感冒，but if you do, you still need 7 days.
