     What would you do if you were ill? Of course, we would eat some medicines. The most

common disease in the world is the cold. It often starts with a sore throat. If you catch a cold,

you sneeze and your nose runs. You usually have a headache, too. Often you have a cough.

It's not a serious disease, but you can feel quite ill.

     There isn't a cure (良方) for a cold, but you can take medicines to make you feel better.

For example, you can take aspirin to get rid of your headache. It is good to rest and to drink

a lot of water, too. A doctor once told me, "With the right medicine, a cold will last for seven

days. With no medicine, it will go on for a whole week!"

     Where does our medicine come from? A long time ago, people understood that some plants

made them feel better when they were ill. They ate leaves, the roots, the fruit, or the seeds of

plants. For example, the juice of lemons makes a sore throat feel better.

     In modern times, scientists have looked at these plants, and found out which chemicals

(化学物质) are in them. Many of our medicines today are made from those chemicals. There

are some diseases which we can't cure (治愈) yet. Such as, AIDS, cancers...

     And nobody has found a cure for old age. But because of modern medicines, the average

person now lives longer than their grandparents.
