Pollution

Hundreds of years ago,life was much harder than it is today.People didn't have modern machines.There was no modern medicine,either.

Life today has brought new problems.One of the biggest is pollution.Water pollution has made our rivers and lakes dirty.It kills our fish and pollutes our drinking water.Noise pollution makes us talk louder and become angry more easily.Air pollution is the most serious kind of pollution.It's bad to all living things in the world.

Cars,planes and factories all pollute our air every day.Sometimes the polluted air is so thick that it is like a quilt over a city.This kind of quilt is called haze (雾霾).

Many countries are making rules to fight against pollution.Factories must now clean their water before it is thrown away,and they mustn't blow dirty smoke into the air.

We need to do many other things.We can put waste things in the dustbin and not throw it on the ground.We can go to work by bus or with our friends in the same car.If there are fewer people driving,there will be less pollution.

Rules are not enough.Every person must help to fight against pollution.

Potato chips are very popular in the world. Do you know how they were invented (发明)? In 1853, a native (本土的) American named George Crum made the first potato chips. Crum was a chef (厨师) in an expensive restaurant in Saratoga Springs, New York. One day, a customer (顾客) did not like the French fries. He said they were cut too thick. That day Crum was in a bad mood, so he cut the potatoes really, really thin and he cooked them for a long time until they were very crispy (酥脆的). He wanted to make the customer dislike them. But the customer loved them very much and asked for more.

Other people wanted Crum’s potato chips. Now, there was a new food on the menu—Saratoga chips. Soon Crum opened his own restaurant and made his special chips. It took a long time to make potato chips. People peeled the potatoes by hand. Then in 1920, the automatic (自动的) potato peeler changed everything. Now it was faster and easier to make potato chips. Now potato chips were not a specialty. They were a popular snack food, but only in the north.

A salesman named Herman Lay wanted to sell potato chips in the south. He sold potato chips in bags. His business grew. Today, Americans eat a lot of potato chips every day.
