Brazil has become one. of the developing world’s great successes at reducing population growth but more by accident than design. While countries such as India have made joint ef??forts to reduce birth rates, Brazil had better results without re??ally trying, says George Martine at Harvard.

Brazil’s population growth rate dropped from 2. 99% a year between 1951 and 1960 to 1. 93% a year between 198 land 1990, and Brazilian women now have only 2. 7 chil??dren on average. Martine says this figure may have fallen still further since 1990, an achievement that makes it the envy of many other Third World countries.

Martine puts it down to, among other things, soap operas (肥皂剧) and installment (分期付款) plans introduced in the 1970s. Both played an important, although indirect, role in low??ering the birth rate. Brazil is one of the world’s biggest produc??ers of soap operas. Globo, Brazil’s most popular television net??work, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy characters living the high life in big cities.

Although they have never really tried to work in a mes??sage towards the problems of reproduction, they describe mid??dle and upper class values: not many children, women work??ing, says Martine. They sent this image to all parts of Brazil and made people conscious (有意识的) of other patterns of behaviour and other values, which were put into a very attrac??tive package.

Meanwhile, the installment plans tried to encourage the poor to become consumers. " This led to an enormous change in consumption (消费) patterns and consumption was incom??patible (不相容的) with unlimited reproduction," says Mar??tine.

A. haven’t given much attention to birth control

11. Soap operas have helped in lowering Brazil’s birth rate be??cause ________.

A. they keep people sitting long hours watching TV

B. they have gradually changed people’s way of life

C. people are drawn to their attractive package

D. they popularize birth control measures

12. What is Martine’s conclusion about Brazil’s population growth?

A. The increase in birth rate will increase consumption.

B. The desire for consumption helps to reduce birth rate.

Li Denghai, with his muddy boots and tanned(晒黑的) face, may not look like he is one of China’s famous agricultural pioneers. But the 61-year-old man from Shandong Province has made scientific breakthroughs(突破), which made great contributions to China’s food security(安全). His main work has been in achieving the higher output of corn production.

Li, who holds the world record for the highest output of summer corn, once says, “Corn has a life; it sings and dances. If you listen clearly, it can speak to you.” He started his research in 1969 when he was 20 and just dropped out of a high school. He then read an article which pointed that corn output per mu in the USA was six times higher than that in China. He was shocked and set out to work on just a small piece of land round the clock to see if he could increase the output. He often went to the field with a flashlight late at night, if he had been away during the day. By careful nurturing (照料) he managed to double the output.

Li Denghai was awarded the “China Award for Significant Contribution to the Maize (玉米) Industry” in 2005, and the same year the company named after his own name came into the market on the Shenzhen Stock Exchange. Li, however, is never happier than when he is in the middle of his cornfields. “I can forget my tiredness when talking to my corns,” he says.
