　　Do you know what a cold is?Have you ever had a cold in the nose?

　　When you have a cold, liquid runs from your nose, and you are ill．A cold is not a bad illness．We call this illness“a cold”or“a cold in the head”, because people think that cold air causes illness．They say, “I went out of my warm house into the cold air．I felt cold．So I caught a cold．”

　　Many people catch a cold in winter．But cold air doesn't always cause a cold．You catch a cold in summer when the air is not cold．In fact, germs(细菌)cause a cold．The germs get into your mouth or into your nose．Then you have a cold．

　　When you have got a cold, do not go out and give it to other people．Other people do not want it．When you have a cold, stay in your house．You'll soon be well．
