In China, many people are leaving the countryside to find jobs in the cities, because the countryside is much poorer than the city, and often there isn't much work there. Services such as hospital and transport （交通） are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.

    But in the big cities of Europe like London or Pads, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt （尘土） of the city, and they are tired of the crowded streets, crowded trains and buses. They don't want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there.

    So they move out of the cities. Some don't go very far, just a little way out of the city, to the towns near the cities, other people move to the real countryside with sheep, cows and green fields. There, they start new lives and try to make new friends.

    Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it was a big mistake. They don't make so much money and there isn't much work to do. People in the countryside are very different and aren't always very friendly.

     As a result, quite a lot of people who have moved to the countryside move back to the city. "It's wonderful to see crowds in the streets and cinema lights," they say.

Did you visit the Shanghai World Expo last summer? What impressed (给……留下印象)  you? 21st Century Kids invites four kids to talk about their experiences. They are back from the Expo. What did they bring us? Let’s see what they have to say.

I went to the SAIC-GM Pavilion (上汽集团通用汽车馆). I found my dream car there. It is a green car. Its name is “Leaf”. Chinese engineers made the car. Its roof is in the shape of a leaf. The roof takes in CO₂ and changes it into electricity for the car.

The Japan Pavilion is full of high technology. The “Wonder Camera” is cool. It can find a smiling face in a crowd. When you’re smiling, it takes a photo of you. I want to invent something like that in the future.

My favorite pavilion is the Germany Pavilion. I watched the Energy Source show. Visitors made a ball swing back and forth (来回摇摆) by using only their voices. It’s amazing! Although we had waited for quite a long time before we entered the hall, I think it is well worth seeing with your own eyes.

I like painting, so my parents took me to the France Pavilion to see the famous paintings. But the French cooks caught my eye. I saw them cook. My mom told me that they are some of the best cooks in the world. The dish they cooked looked like a painting. So, being a cook is my second dream job.
