How many of your classmates drink cola now? Nearly everyone (drink) it. Did you know that cola was a kind of medicine about 200 years ago?
John Stith Pemberton was a doctor from America. He said to his friends, "I spent many months (experiment) to find a kind of medicine for headaches. I (mix) up different oils (油) and ingredients together and heated them until I found something helpful. So far, I (succeed) already. I put the medicine into bottles (瓶) and began selling it in drugstores. The people have to (add) water to it before drinking."
Then, how did cola go from being a medicine to a soft drink? That (come) by accident.
One day, a man who had a headache came into a drugstore. He asked for a bottle of cola. He wanted (take) it right away, so he asked the clerk to add some water to the medicine while he (wait). But there was no hot water in the drugstore, The clerk used soda water (苏打水) instead. The man agreed. After drinking it, the man said it tasted wonderful. From then on, it (begin) to become more popular.
Today cola (sell) in most countries around the world. Although it is no longer used to treat headaches, it is still very popular and fills people with energy.
