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 ef­forts to reduce birth rates, Brazil had better results without re­ally 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 chil­dren 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 low­ering the birth rate. Brazil is one of the world’s biggest produc­ers of soap operas. Globo, Brazil’s most popular television net­work, 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 mes­sage towards the problems of reproduction, they describe mid­dle and upper class values: not many children, women work­ing, 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 attrac­tive 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 incom­patible (不相容的) with unlimited reproduction," says Mar­tine.

9. According to the passage, Brazil has lowered its population growth ________.

A. by educating its citizens               B. by careful family planning

C. by developing TV programmes                    D. by chance

10. According to the passage, many Third World countries

A. haven’t given much attention to birth control

B. would soon join Brazil in controlling their birth rate

C. haven’t yet found an effective measure to control their population

D. haven’t realized the importance of TV plays in family planning

11. Soap operas have helped in lowering Brazil’s birth rate be­cause ________.

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.

C. Consumption goes with reproduction.

D. A country ‘s production is limited by its population growth.

单项选择题

People can get emotional about immigration. Bill O’Reilly, a talk-show host, devoted a recent segment to the story of an illegal alien who got drunk and accidentally killed two attractive white girls with his car. If only he had been deported for previous misdemeanours, Mr. O’Reilly raged, those girls would still be alive. Another talk-show host, Geraldo Rivera, during an on-air shout-joust(争吵) with Mr. O’ Reilly, denounced his demagogic choice of story-angle as" a sin".

President George Bush tried again this week to bring a more rational tone to the debate. He urged the new Democratic Congress to revive the immigration reforms that the old Republican Congress killed last year. His proposal was broadly the same as before. He said he wanted to make it harder to enter America illegally, but easier to do so legally, and to offer a path to citizenship for the estimated 12m illegals who have already snuck in.

The first part faces few political hurdles and is already well under way. Mr. Bush expects to have doubled the number of Border Patrol agents by the end of next year. The new recruits are being trained. And to defend against the invading legions of would-be gardeners and hotel cleaners, the frontier is also equipped with high-tech military gizmos(小发明), such as unmanned spy planes with infra-red(红外) cameras. This may be having some effect. Mr. Bush boasted that the number of people caught sneaking over the border had fallen by nearly 30% this year.

And the controversial part of Mr. Bush’s immigration package--allowing more immigrants in and offering those already in America a chance to become legal -- is still just a plan. House Republicans squashed it last year. Mr. Bush senses a second chance with the new Democratic Congress, but Democrats, like Republicans, are split on the issue. Some, notably Ted Kennedy, think America should embrace hard- working migrants. Others fret that hard-working migrants will undercut the wages of the native-born.

Mr. Bush would like to see the pro-immigrant wings of both parties work together to give him a bill he can sign. The Senate is expected to squeeze in a debate next month. The administration is trying to entice law-and-order Republicans on board; a recent leaked memo talked of substantial fines for illegals before they can become legal and" much bigger" fines for employers who hire them before they do.

The biggest hurdle, however, may be the Democrats’ reluctance to co-operate with Mr. Bush. Some figure that, rather than letting their hated adversary share the credit for fixing the immigration system, they should stall until a Democrat is in the White House and then take it all. So there is a selfish as well as a moral argument for making a deal.

According to the text, Mr. Bush’s plan was opposed by ()

A. Bill O’Reilly

B. Geraldo Rivera

C. Ted Kennedy

D. the pro-immigrant wings
