　　Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in a bid to cut the emission of greenhouse gases blamed for global warming.

　　Thanks to special bacteria in their stomachs, kangaroo farts contain no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas.

　　While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide, livestock passing wind contribute a surprisingly high percentage of total emissions in some countries.

　　"Fourteen percent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland state government.

　　"And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said.

　　Researchers say the bacteria also makes the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.

　　But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.

　　Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.

　　The idea is controversial（争议）, but about 20 percent of health conscious Australians are believed to eat the national symbol already.

　　"It's low in fat, it's got high protein levels and it's very clean in the sense that basically it's the ultimate free range animal（散养动物）," said Peter Ampt of the University of New South Wales's institute of environmental studies.

　　53. According to the passage, global warming is now mainly caused by _____ .

　　A. methane

　　B. carbon dioxide

　　C. livestock passing wind

　　D. not mention in this passage

　　54. What does the underlined phrase “the idea”（paragraph 9）refer to?

　　A. Australians should give kangaroo-style stomachs to cattle and sheep.

　　B. The bacteria could make the digestive process much more efficient.

　　C. Australians should farm fewer cattle and sheep and just eat more kangaroos.

　　D. The bacteria could potentially save millions of dollars in feed costs for farmers.

　　55. Some Australians begin to eat kangaroos because _____.

　　A. The kangaroos’ farts（放屁）contain no methane

　　B. The kangaroos have a special bacteria

　　C. The kangaroos are the national symbol in Australia

　　D. The kangaroos are low in fat and high in protein

　　56. How will Australian scientists solve the problem of global warming?

　　A. Eating more kangaroos.

　　B. Killing more cattle and sheep.

　　C. Letting cattle and sheep pass less wind.

　　D. Transferring the special bacteria in kangaroos’ stomachs to cattle and sheep.

　　Quality after-school programs are designed to improve academic performance, decrease youth crimes and other high-risk behaviors, and help young people grow into healthy, successful adults.

　　The effect of quality after-school programs on academic performance is clear. Studies show that students who take part in such programs show better work habits, higher rates of homework completion, improved grades, and higher scores on achievement tests. They also have fewer absences and are less likely to blame. After-school programs also influence high-risk teen behavior. Various studies show decreased rates of crime, drug use, and teen sex among youth who join in well-run after-school programs when compared to similar youth who do not. Finally, after-school programs play an important role in supporting the following fields of development: physical development, mental development and social development. Thus, one can safely say that after-school programming is an effective method to help young people become contributing members of society.

　　Although there is enough proof from both small and large assessments that after-school programs can make a positive difference, it is important to note that not all programs are equal.

　　First, dosage（时量）matters —young people who attend the most hours over the most years benefit more than members who attend less often or over a shorter period of time. Next, after-school programs make a bigger difference for those students who need help most and have the fewest choices. Finally, program qualities matter. After-school programs work best when they create unique opportunities for youth. They should provide opportunities, skill building meaningful involvement（参与）, expression suggestion, service, and work. Staff characteristics make an important difference in the quality of a program. The adults should treat youth as partners, create safe and fair environment, encourage personalized（个性化的）involvement, and actively create learning opportunities. In short, although after-school programs have promising future, how they are designed and run matters.
