【题目】Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.

Famers can also call on the services of their local hunt to control the fox population. Hunting consists of running after a fox across the countryside, with a group of specially trained dogs, followed by men and women riding horses. When the dogs eventually catch the fox, the kill it or a hunter shoots it.

People who take part in hunting think of it as a sport. They wear a special uniform of red coats and white trousers, and follow strict rules of behavior. But owning a horse and hunting regularly are expensive, so most hunters are wealthy.

It is estimated that up to 100,000 people watch or take part in fox-hunting. But over the last couple of decades the number of people who are against fox-hunting, because they think it is brutal(残暴的), has risen sharply. Nowadays it is rare for a hunt to pass off without some kind of conflict between hunters and hunt opponents (阻止者). Sometimes these incidents lead to violence, but mostly opponents discourage the hunt by misleading riders and disturbing the trail of the fox's smell, which the dogs follow.

Noisy conflicts between hunters and opponents have become so common that they are almost as much a part of hunting as running after foxes itself. But this year supporters of fox-hunting face a much bigger threat to their sport. A Labour Party member of Parliament(英国议会), Mike Foster, is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.

【1Wealthy people in Britain have been hunting foxes to ______.

【4What can be inferred from this passage?

B. Killing foxes with poison is not allowed by the law.

C. Hunting foxes with dogs is considered cruel and violent.

D. Fox-hunting causes conflicts between hunters and farmers.

【题目】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 dioxidelivestock 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 Klievea 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 basethey'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 bacteriabefore 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 fatit'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.

1 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

2 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.

3How 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.
