Are the lives of city kids the same as those in villages? In lots of ways, they are very differen
t. But what are those differences?
Hu Peng from Wuhan and four of his friends decided to find out. Earlier this month, they went to live for a week in Caidian, a village near Wuhan. Hu and his Junior l classmates went door to door in Caidian and asked kids lots of questions. They want to learn more about village kids' everyday lives, so they asked questions like this: Do your parents teach you how to do the housework? How much money do you usually spend on dinner? What would you do if a thief came into your house? They also asked 150 city kids t
he same questions.
On April 12, the team gave a report to their class. They told about many differences between children's lives in cities and those of children in villages. The biggest difference is about independence. Hu's team found that 60 percent of city kids can't do much housework, but 90 percent of village kids can care for themselves.
City kids told Hu they care about schoolwork a lot, and the
y have no time for washing clothes or making their beds. Village kids said they help their parents a lot : cooking, cleaning the houses and feeding pigs. Hu's team also found that village kids have less pocket money. Many have never used computers. They like playing in rivers or on mountains. Some don't even like to make new friends.
Hu and his friends said their trip gave them more self- confidence (自信) because they have done something by themselves. But it also worried them a bit because they found they still have a lot to learn. "When we grow up, our parents can't take care of us," Hu said. "We have to learn to take care of ourselves. " Shen Guanquan, one of Hu's friends said, "When people learn to care for themselves, they learn to do lots of difficult things. "
