One of the most wonderful things about having a positive attitude is that it can touch many people, and it often exists in our everyday life.

Recently, I stopped by a store to get a newspaper and a bottle of drink. The young woman at the check-out counter said, “That’ll be three dollars in all please.” She then glanced down at the paper I was buying and said. “I’m sick and tired of all this negative stuff-on the front pages. I want to read some good news for a change.” She then said, “In fact, I think soemone should just publish a Good News newspaper--- a paper with wonderful, inspirational stories about people over-coming difficulty and doing good things for others. I’d buy one every day!” she then thanked me for coming in and said, “Maybe we’ll get lucky tomorrow; maybe we’ll get some good news.” And she laughed. She made my day.

The following day after my business appointments. I dropped by the same store again to pick up bottled water and a piece of newspaper, but a different young lady was behind the counter. As I checked out I said “Good afternoon” and handed her my money. She said nothing, not a word, not a smile or not a gesture. She just handed me my change and in a negative tone ordered “Next!”

It hit me right between the eyes: Two people, the same age; one made me feel great, and the other, well, made me feel that I had inconvenienced her by showing up.

Every morning you should ask yourself this important question. “Who do I want to be today? The Grouch(不高兴的人) or ‘The Good News Girl?’” Your answer will go a long way toward determining the joy and happiness that you will experience in your life.

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

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 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(争议), 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(散养动物)," said Peter Ampt of the University of New South Wales's institute of environmental studies.

56. 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

57. 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.

58.  How 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.
