4．Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out，which are thought to be responsible for global warming．
Thanks to special bacteria in their stomachs，kangaroo flatulence（肠胃气胀）contains no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas．
While the usual image of greenhouse gas pollution is a huge chimney pushing out carbon dioxide，animals at home contribute a surprisingly high percentage of total emissions in some countries．"Fourteen percent of emissions from all sources in Australia is from methane from cattle and sheep，"said Athol Kleve，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 50percent，"he said．
Researchers say the bacteria also make 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 （分离） 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．People are still arguing about this，but about 20percent 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 free-range （放养的） animal，"said Peter Amp of the University of New South Wales's institute of environmental studies．
28．Scientists try to give kangaroo-style stomachs to cattle and sheep toB．

30．From this passage we can infer thatA．
A．scientists still don't know how to transfer the bacteria to cattle and sheep．
B．people in Australia depend on kangaroos for food at the present time．
C.14% of the greenhouse gases in New Zealand is from cattle and sheep．
D．nobody in Australia will be allowed to farm cattle and sheep in the future． 试题答案
分析 文章主要是介绍了一项最近关于温室气体排放的研究．为了减少导致全球变暖的温室气体的排放，澳大利亚科学家目前正在想办法将牛羊胃变成袋鼠式的胃．袋鼠胃中有一种特殊的细菌能使其放的屁中不含有甲烷．科学家想将这种细菌移至牛羊的胃中，以抑制它们所排放的大量有害气体．另一组科学家建议澳大利亚人应少养牛羊，多吃袋鼠肉．
解答 28-30．BCA
28题答案：B考查推理判断．从文章第一﹑二自然段"为了减少导致全球变暖的温室气体的排放，澳大利亚科学家目前正在想办法将牛羊胃变成袋鼠式的胃．袋鼠胃中有一种特殊的细菌能使其放的屁中不含有甲烷．科学家想将这种细菌移至牛羊的胃中，以抑制它们所排放的大量有害气体．"可推断得知B选项为正确答案．
29题答案：C考查细节推理，根据文章倒数第二段的Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers…before they can even start to develop a way of transferring it（ bacteria）to cattle and sheep．研究人员说细菌使消化过程更加有效而且能潜在地为农民的喂养成本节省数以百万计美元…在他们开始研究一种将这种细菌植入到牛和羊身上之前．可知本题答案为C选项．
30题答案：A考查细节推理，根据文章倒数第三段的But it will take researchers at least three years to isolate （分离） the bacteria，before they can even start to develop a way of transferring it to cattle and sheep．但是甚至在他们开始研究将这种细菌植入到牛和羊身上之前研究者还要至少花费三年的时间来分离这种细菌．可知目前科学家还不知道如何将这种细菌植入到牛和羊身上，故本题答案为A选项．
点评 本文是一篇科教类阅读，题目涉及多道细节理解题，做题时结合原文和题目有针对 性找出相关语句进行仔细分析，结合选项选出正确答案．推理判断也是要在抓住关键句子的基础上合理的分析才能得出正确的答案．
完形填空,阅读下面短文,从短文后各题所给的四个选项(A、B、C和D)中,选出可以填入空白处的最佳选项。
