Recently, hazy(霾)weather has become a serious problem in many parts China. Heavy haze has spread quickly all over China. It has influenced people's lives in the whole country from the north to the south, including Beijing, Hebei, Shanxi, Jiangsu and Guangdong. People even can't see each other when they stand about 50 meters from each other. It can cause lots of traffic accidents. So the highways are closed and the flights are put off on hazy days.

Cities like Shanghai and Nanjing have been covered with the grey sky for the past several weeks. Many walkers in the street had to wear masks(口罩). In the Lukou airport in Nanjing, Jiangsu Province, more than 60 flights were cut out on Saturday because of the hazy weather, which also made primary and middle schools and kindergartens stop having classes on Thursday and Friday in Nanjing. Earlier this week, the Ministry of Environmental Protection said that there were several reasons for the heavy haze. Especially Bad weather conditions made it difficult for polluting things to disappear.

In order to clean up the air , the Chinese government now plans to cut coal use and increase cleaner production.

“We must face the problem,” said Yan Naiqiang, a professor of environmental science at Shanghai Jiao Tong University. “It will take a long time to control and improve the weather condition.”

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.
