    We may probably see the passage in the section of the Website. A. Entertainment B. Lifestyle C. Consumers D. Science and technology D 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 methaneand 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, 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," said Peter Ampt of the University of New South Wales's institute of environmental studies. 【查看更多】

    第三部分：阅读理解（共20小题，每题2分，满分40分）

    阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳答案，并在答题卡上将该项涂黑。

    WASHINGTON -Tofu（豆腐）and Soyaburgers (豆饼) may be coming to American school lunch menus. What will the kids say?

     “Terrible,” said Greg Dudzinski, 17, of Ripon High School in Wisconsin, as he toured the US capital.

    “The regular hamburgers are bad enough, so soyaburgers would be a lot worse, offered Zach Richey, 13, of Scottsboro Junior High in Alabama, another tourist.

    But the United States government – hoping to reduce the amount of fat that children are eating –has approved the use of soy as a meat substitute in meals for schools and day-care centers.

    Not all kids dislike the change. Mariel Spano, 17, of sandy Greek High School in New York, also visiting the capital, said she likes soyaburgers：  “There is less fat, and they are better for you… They taste the same, and they are just as good.”

    The government tried to make soy a meat substitute nearly 20 years ago, but later dropped the ideA．At the time, the plan was intended as a cost-cutting move. US Agriculture Department officials say that their purpose now is only to make meals healthier.

    Schools are likely to increase the amount of soy that is mixed with hamburgers and other foods already on their menus, and they will also be looking for food companies to develop new soy products that children will like. “ I can’t see putting tofu on a student’s plate and having a good acceptance. I can see taking a product that is familiar to the students and adding a large amount of soy to it and having it to be acceptable,” said Jill Benza, director of food services for the Mesa, Arizona schools.

    1．What is the newspaper report mainly about?

           A．The difficulty in using soy products for US schools.

    B．Various opinions on soy products for US schools.

           C．The plan that is made by the US government for school lunch.

           D．Healthy foods for students in US schools.

    2．Where did the interviews most probably take place?

           A．In food companies.              B．In schools.

           C．In Washington.                   D．In some other states.

    3．We may learn from the text that _________________________.

           A．soyaburgers taste better than hamburgers.   

           B．hamburgers are healthier than soyaburgers.

           C．soyaburgers cost less than hamburgers.     

           D．hamburgers cost less than soyaburgers.

    4． What Jill Benza said shows that ___________________________.

           A．students have not yet been used to soy products.

           B．it is hardly possible to make soy products popular.

           C．he does not like the change in meals for students.

           D．schools are unwilling to change the lunch menus.
