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(贫困) 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.

According to scientists’ research, the month in which babies are born could affect them in some ways.

Babies born in spring get sick easily. Children born under Aquarius (Jan. 21st—Feb. 19th) may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn. Scientists believe many of the differences can be explained by the mother’s exposure to sunlight in pregnancy (怀孕). Sunlight helps lead to the production of vitamin D in the body. The lack (缺乏) of vitamin D in the first months of life may have a bad effect on health.

Vitamin D is called the “sunshine vitamin”. It has a good effect on health. A study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the US showed that people born in autumn lived about 160 days longer than those born in spring.

Professor Russell Foster said the conclusions were surprising and interesting. He added, “These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth.”

1.A child’s season of birth can affect all the following things EXCEPT ________ according to the first two paragraphs.

A. his health　　 B. his height

C. his length of life　　 D. his quality of being clever

2.What does the underlined word “exposure” mean in Chinese?

A. 偏爱　　 B. 抗拒　　 C. 过敏　　 D. 暴露

3.What can we know about vitamin D according to the passage?

A. It comes from sunlight.　　 B. It helps people live longer.

C. Sunlight prevents its production.　　 D. It does harm to people’s health.

4.Which of the following is TRUE according to the passage?

A. Women should get enough sunlight in pregnancy.

B. Children born under Aquarius are cleverer than those born in autumn.

C. People born in May will live longer than those born in October.

D. Professor Russell Foster is interested in star signs and believes in them.
