任務(wù)型閱讀。

Most new babies were born in the developing countries. These countries are found in Africa, South America and 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, about one quarter of the world’s population lived in the developed countries. By 2050, these countries will be home to only about one tenth of the world’s people.

In the developing countries, more than one billion people are still living below the poverty(貧困) line. These people do not have enough food to eat and they live in poor housing conditions. Children get little time at school and suffer (遭受痛苦) from many kinds of diseases.

At the beginning of the 21st century, the world’s population was around six billion. The U.N. has said that the world’s population will level off (平穩(wěn)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 (穩(wěn)定的), or even falls.

根據(jù)短文內(nèi)容，回答下列問(wèn)題。

1.In 1950, what percent of the world’s population lived in developing countries?

________________________________________________

2.There will be twelve and a half billion people on the earth in 2100, won’t there?

________________________________________________

3.將文中畫線部分翻譯成漢語(yǔ)。
