故画竹必先得成竹于胸中,执笔熟视,乃见其所欲画者,急起从之,振笔直遂,以追其所见,如兔起鹘落,少纵则逝矣。与可之教予如此。予不能然也,而心识其所以然。夫既心识其所以然,而不能然者,内外不一,心手不相应,不学之过也。故凡有见于中,而操之不熟者,平居自视了然,而临事忽焉丧之,岂独竹乎?(苏轼《文与可画筼筜谷偃竹记》)

     Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the

greenhouse gases they send out, which is thought to be responsible for global warming.

     Thanks to special bacteria in the stomachs, kangaroo flatulence (肠胃气胀) contains no methane (甲

烷) and scientists want to transfer that bacteria to cattle and sheep which produce large quantities of the

harmful gas.

     While the usual image of greenhouse gas pollution is a huge smokestack pushing out carbon dioxide,

farm animals' passing wind contributes to a surprisingly high percentage of total emission (排放物) in

some countries.

     "Fourteen percent of emissions from all sources in Australia is from 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 are actually up around 50 percent," 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 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. And about twenty 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 free-range

(放养的) animal," said Peter Ampt of the University of New South Wales's institute of environmental studies.

1. The passage mainly talks about _____.

A. a better way to prevent air pollution

B. the danger of methane from farm animals

C. possible solutions to protecting environment

D. a recent research on global warming

2. Scientists intend to put the bacteria into cattle and sheep in order to _____.

A. prevent them from sending out harmful gases

B. promote Australian farming

C. protect Australian ecosystem

D. make the most of the special bacteria

3. Another possible solution to the problem is _____.

A. to reduce the number of animals raised on farms

B. to keep more kangaroos rather than sheep and cattle

C. to eat more plants rather than beef and mutton

D. to grow more trees to absorb carbon dioxide

4. From the passage we learn that _____.

A. it is easy to transfer the bacteria to cattle and sheep

B. farm animals are to blame for global warming in some countries

C. cattle and sheep produce more methane than kangaroos

D. one fifth of Australians already eat their national symbol
