China covers large areas and has a great population. Different living habits have always been an interesting topic in the country. Recently, another difference between southern Chinese and northern Chinese became a hot one: The way people shop at markets.

People from southern China say that they always buy what they need for just one or two meals. It is normal for them to buy half of a Chinese cabbage, two potatoes and 0.25 kilograms of beef at a time.

However, one may be laughed at if he does this in the north. Instead, buying vegetables and meat enough for a week is usual.

Also, you can buy a small amount(数量) of fruit, such as a single apple or pear, each time in the south. Shopkeepers even help you peel( 去 皮 ) and cut them. But shopkeepers in the north hardly offer such service. And many fruits are sold in baskets and boxes.The difference could be due to the different weather.

Food can be kept for a long time in the north, as it is usually cold and dry there. Many northern Chinese have the habit of keeping food, especially for the long winter. But the hot and wet weather in the south makes southern Chinese buy just enough food for one meal or one day, or else the food may go bad.

The world’s largest radio telescope was finished on Sept. 25, 2017 in China.

FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province. The giant dish is built on a howl-like valley.

The surrounding area has "radio silence" as there are no towns and cities within a 5-kilometer radius(半径范围) and only one county center within 25 kilometers.

FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals (信号).

The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy(银河系) and explore the origins(起源)of the universe. "Any of its discoveries will lead to a Nobel Prize," said Joseph Taylor, a Noble Prize winner.

The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.

1.Where was FAST developed?

A.In China. B.In Russia. C.In America.

B.Noisy towns are around the telescope within a 5-kilometer radius

C.The second-largest radio telescope is made up of 4,450 panels

5.How long did it take to finish the FAST project?
