Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut he 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 billowing smokestack (烟囱) pushing out carbon dioxide, farm animals’ passing wind contribute a sur­prisingly high percentage of total emissions (排放物)in some countries.

“Fourteen percent of emissions from all sources in Australia are from enteric 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 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 (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.      

The idea is controversial (有争议的), 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 free-range (放养的) animal,” said Peter Amp of the University of New South Wales's institute of environmental studies.

1.Scientists intend to put bacteria into cattle and sheep _________.

A. so that they can make full use of special bacteria

B. to help Australian farmers to earn more money

C. so that they can protect Australian ecosystem

D. to prevent them from sending out harmful gases

2.Athol Kleve seems to believe that ________.

A. cattle and sheep produce more carbon dioxide

B. less cattle and sheep are raised in New Zealand

C. farm animals are responsible for greenhouse gases

D. New Zealand has the most animals in the world

3.What do the underlined words “the idea” in para­graph 9 refer to?

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

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

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

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

4.Which of the statements is the advantage Peter Amp lists about kangaroo?

A. it is rich in protein                                    B. it is cheaper than beef

C. it is high in fat                                                       D. it is more delicious than sheep

【解析】

试题分析: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。

1.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D

2.考查细节理解。从第四段的句子:“Fourteen percent of emissions from all sources in Australia is from enteric(肠的) methane from cattle and sheep,” said Athol Klieve, 可知Athol Klieve认为,温室气体越来越多主要是因为农场的动物造成的。选C

3.猜词题:从上面第八段的内容:Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.可知另一组科学家建议澳大利亚人应少养牛羊,多吃袋鼠肉。这里的另外一种想法就是这个,选A。

4.细节题:从最后一段的句子:“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,” 可知Peter Amp 认为袋鼠肉富含蛋白质,选A

    The retired professor, Archibald A. Hill in Lucasville, USA could tell us the story. Ninety-seven years ago, two of Mr. Archibald Hill’s aunts, Miss Patty Hill and Miss Mildred Hill were asked to write some songs for a book called “Song Storied for the Sunday Morning”. Miss Patty Hill and Miss Mildred Hill were both kindergarten teachers then. They loved children very much and wrote many beautiful songs for the book. One of them was the famous “Good Morning to You.” The song said, “Good morning to you, good morning to you, dear children, good morning to all.” This song was very popular at that time among kindergarten children. But not many grown-ups knew it. A few years later little Archibald was born. As his aunt, Miss Patty Hill sang the song “Happy Birthday” to the melody(曲调)of “Good Morning to you” to her little nephew(侄子). She sang the song like this: Happy birthday to you! Happy birthday to you! Happy birthday, dear Archie! Happy birthday to you!

Fire can help people in many ways. But it can be very dangerous. Fire can heat water, warm houses, give light and cook. But fire can burn things, too. It can burn trees, houses, animals or people. Sometimes big fire can burn forests.

Nobody knows for sure how people began to use fire. But there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man very, very long time ago. He went up to the sun by a rope (绳子) and brought fire down.

Today people know how to make a fire with matches (火柴). Children sometimes like to play with them. But matches can be very dangerous. One match can burn a piece of paper, and then it might burn a house. A small fire can become a big fire very fast. Fire kills many people every year. So you must be careful with matches. You should also learn to put fires. Fires need oxygen (氧气). Without oxygen they will die. Cover a fire with water, sand or sometimes with your coat. This keeps the air away from a fire and kills it. Be careful with fire, and it will help you. Be careless with fire, and it will burn you.

PART THREE READING COMPREHENSION(30 points)

Directions: Read the following three passages.Each passage is followed by several questions or unfinished statements.For each of them there are 4 choices marked A,B,C and D.Choose the one that fits best according to the information given in the passage.

Next time you find yourself drenched (湿透) in an unexpected heavy rain, look on the bright side – it will be a memorable experience. While wet weather may make us feel gloomy, it sharpens the memory and improves our recall. But those who feel in a good mood because it’s a sunny day are able to remember less well, according to memory tests carried by Australian researchers.

Professor Joe Forgas, who led the research, said: “It seems strange but a little bit of sadness is a good thing. People performed much better on our memory test when the weather was unpleasant and they wee in a slightly negative mood. On bright sunny days, when they were more likely to be happy, the flunked it.”

The tests were carried out on shoppers at a store in Sydney, where researchers randomly placed ten small objects on the check – out counter. On rainy days, sad music was played in the store. When it was bright and sunny, customers heard cheery music. This was done to further influence them towards negative or positive moods. After shopping, customers were asked how many of the objects they could remember. Their scores were three times higher when the weather was had and they were feeling angry, compared with those tested on sunny days. The results were published in Journal of Experimental Psychology. A report on the findings said: “They point to a growing body of evidence that the way people think, the quality of their judgments and the accuracy of their memory are all significantly influenced by positive and negative moods.”

Professor Forgas said, “We found that weather – inducted negative mood improved memory accuracy. Shoppers in a negative mood showed better memory and higher discrimination ability.”

A worse mood helped to focus people’s attention on their surroundings and led to a more thorough and careful thinking style, while happiness increased confidence and forgetfulness.

Being happy tends to promote a thinking style that is less focused on our surroundings. In a positive mood we are less likely to make more snap (匆忙的) judgments about people we meet. Mild negative mood, in turn, tends to increase attention to our surroundings and produce a more careful, thorough thinking style.

Accurately remembering everyday scenes is a difficult task, yet such memories can be on importance in everyday life. Surprisingly, the influence of mood states on the accuracy of real-life memories is still poorly understood.

56.What’s the major function of Paragraph 1?

A.To attract readers’ interest.     

B.To introduce the theme of the whole passage.

C.To generalize the whole passage.   

D.To describe a memorable experience.

58.In the research, researchers play different music to         .

A.make customers become sadder or happier

B.help customers choose what they want

C.promote customers to buy more goods

D.get customers to make a quick choice

59.According to Joe Forgas, on sunny days, people         .

A.will make careful judgments on others

B.tend to pay more attention to their surroundings

C.will have more confidence

D.will have a better recall

60.What can we know from the research?

A.Forgetfulness is rather troublesome.

B.It’s important to feel in a good mood.

C.It’s memorable to experience a rainy day.

D.Gloomy days are good for memorizing things.
