do you live in a city? do you know how cities began? long long ago, the world had only a few thousand people. these people moved from one place to another. they moved over the land, hunting animals for food.
no one knows how or when these people learned about growing food. but when they did， their lives changed. they did not have to look for food any longer. they could stay in one place and grow it.
people began to live near one another, so the first village was established. many people came to work in the villages, and these villages became even larger.

most new people were born in developing countries. these countries are found in much of africa, south america and some parts of asia. in the developed countries of europe and north america, the population is growing very slowly. this is because women in these countries have, on average(平均), only one or two children. in the developing countries, many women have five or more children. in 1950, around one quarter of the world’s population lived in the developed countries. by 2050, these countries will be home to only around one tenth of the world’s people.123456789101112131415161718192021222324

at the beginning of the 21st century, the world’s population was around six billion people. the u.n. has said that the world’s population will level off(平稳下降) at 12.5 billion by the year 2100. other groups think the world’s population will continue to grow, reaching 14 billion before it becomes stable(稳定的), or even falls.
