【题目】A new study has found some secrets of people’s understanding of large numbers.

Researchers studied a group of people who were born deaf and never learned any spoken language or a formal sign language, but they have developed a gesture system to communicate with people around them. The gestures let them express approximate amounts, but not exact numbers.

“Up to three, they’re fine,” says Elizabet Spaepen, a researcher at the University of Chicago and an author of the study. “But past three, they start to fall apart.” In one test, Spaepen would knock her fist against a study participant’s fist a certain number of times and then ask them to respond with the same number of knocks. “If I were to knock four times on their fist, they might knock on my fist five times,” she says.

The finding offers a clue to just how much language affects our understanding of numbers. That has been a big question since 2004, when other researchers published data on two tribes in the Amazon whose members also lack words for big numbers. “What they have are words that mean one and two,” Spaepen says, “and then they have a word to mean many.”

Members of the Amazonian tribes also had trouble matching numbers larger than three or four. But some scholars felt that these earlier studies failed to prove that language was the reason. They pointed out that the tribes lived in groups that didn’t use money and had no need for exact numbers.

The new research appears to answer that criticism. “It proves that the kinds of problems in understanding numbers that we found in the Amazonian tribes are not due to just the cultural or environmental circumstances,” says Peter Gordon of Columbia University, one of the researchers involved in the earlier studies.

A. cannot communicate with one another

【3】 The tribes involved in earlier studies _________.

A. often dealt with big numbers.

B. didn’t use money in their daily life

C. didn’t have their own language

D. often made trouble for the researchers

【4】 What can we learn from the last paragraph?

A. Peter Gordon is a researcher of the University of Chicago.

B. Peter Gordon thinks less of the new study than his earlier studies.

C. Peter Gordon believes people’s understanding of numbers has nothing to do with cultural circumstances.

【题目】Today, people all over the world are moving out of small villages in the country to go and live in big, noisy cities. They are moving from the peaceful hills, mountains, fields, rivers and streams of the countryside to the busy world of streets, buildings, traffic and crowds. This movement from rural areas to urban areas has been going on for over two hundred years.

In many countries, the main reason people come to live in towns and cities is work. After one or two large factories have been built in or near a town, people come to find work, and soon an industrial area begins to grow. There is usually a residential area nearby, too. The families of these workers need schools, hospitals and shops, so many people come to live in the area to provide these services and a city grows.

In every major city in the world, there is a business district where the big companies have their main offices. In the United States, this area is usually in the city center downtown. It is here that you can see many huge skyscrapers(摩天大楼) and office blocks. The people who work here often travel a long way to work each day. Many of them live in the suburbs of the city, far away from the industrial area and the city center. Some suburbs are very pleasant, with nice houses and big gardens. There are usually parks for children to play in and large department stores where you can buy all you need.

But what is the future of the big cities? Will they continue to get bigger and bigger? Perhaps not. Some major cities have actually become smaller in the last ten years, and it is quite possible that one day we will see people moving out of the major cities and back into smaller towns and villages.

【1】Why do people move to live in cities or towns?

A．Because they can live more comfortably there.

【2】The underlined phrase “a residential area” means an area________.
