Grace Kane hangs onto an Olympic dream of clinging to a granite (花岗岩) wall by her fingertips 70 feet from the ground. The fearless girl is only 10, but already has scaled great heights in the sport of rock climbing.
Last week, Kane won a bronze in the 11andyounger sport class at the USA Climbing Youth National Championships in Atlanta. She was the only competitor of the 31 there with no climbing coach or topflight facilities in which to train. Climbing will become an exhibition at the 2016 Rio de Janeiro Olympics in Brazil. The hope of enthusiasts is that the sport will gain full status in 2020.“I’m already training for that,” said Kane. “Climbing is my passion, my love, and I want to make something of it.”
Her dad took her to climb rocks on her fourth birthday for the first time and today he can’t keep up with her, “It’s the freedom to let loose,” she said. “When I’m up there, I’m so focused and don’t hear anything. I always feel comforted knowing people are supporting me.”
The bronze in Atlanta qualified Kane for the USA team and November’s International Championships in Ecuador. That’s a trip she might have to miss because it’s too expensive.
Kane held a backyard music concert---she played the guitar and the piano and wrote inspirational songs---and raised $600 for her $1,500 trip to Atlanta. She’s also been sponsored by a shoe company, but must rely heavily on donations from family and friends for travel expenses.
Her mom Heather Kane said the family has chosen “to do whatever we need to help her achieve her goals”. One of Grace’s biggest challenges is finding balance in her life. There’s school, her music and church to fit around climbing.
“Climbing is going to mean sacrificing things other kids might pursue,” Grace said. “But it doesn’t bother me. It’s like playing the piano; you can’t take a break or you’ll lose your touch.”
【小题1】What would be the best title of the passage?

A．Rock climbing gains popularity

C．raise enough money for International competitions

D．keep balance between rock climbing and other activities

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

Linus Pauling，the only person who has won two undivided Nobel Prizes，was born in Portland，Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962，long after he had received his Bachelor’s degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it.

He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the “behavior” of molecules(分子) led him from physical chemistry to biological chemistry，especially of the human body. He began with proteins and their main parts，the amino acids(氨基酸)，which are called the“building blocks of life”．In 1950，he constructed the first satisfactory model of a protein molecule，a discovery very important to the understanding of the living cell.

During World WarⅡ，Pauling was a member of the Research Board for National Security，for which he was awarded the Presidential Medal of Merit in 1948. However，the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules，he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures.

From then on，Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons. Through his efforts，The NuclearTestBan Treaty，declaring all nuclear tests to be illegal except underground ones，came into effect on October 10,1963，the same day Linus Pauling was awarded the Nobel Peace.

1.From the first Paragraph，we learn that Linus Pauling________.

A．didn’t study hard while in Washington High School

B．is the only scientist who has won two Nobel Prizes

C．was once badly treated in Washington High School

D．chose to study chemical engineering to earn his living

2.Which of the following things did Pauling pay much attention to at first?

A．The “behavior” of molecules.	B．Physical chemistry.
C．Biological chemistry.	D．The human body.

3.Which of the following is legal according to The NuclearTestBan Treaty?

A．The use of nuclear weapons.

B．Testing hydrogen bomb on the ground.

C．Testing hydrogen bomb on underground.

D．The production of hydrogen bombs.

4.The main idea of the passage is to show________.

A．Linus Pauling’s attitude towards nuclear weapons

B．Linus Pauling’s contributions to the world

C．Linus Pauling’s research on the structure of molecules

D．Linus Pauling’s got the Nobel Prize for Peace

H5N1 avian influenza, commonly known as bird flu (流感), has killed at least 15 people across Asia and was proved in China on January 27. No human cases have been found in the mainland, but 13 of the country’s 31 provinces have reported the disease in poultry.

The Chinese government has taken measures to prevent and control the disease. Poultry within 3 km of infected (受感染的) farms is to be killed and those within 5 km vaccinated (接种疫苗). At the same time, there will be continuous monitoring and daily reports on the disease across the country, and increased production of bird flu vaccines.

Among the 11 Asian countries and regions having bird flu in animals, only Vietnam and Thailand have reported human cases. The people infected were reported to have caught the disease from poultry.

While the World Health Organization ( WHO) says there is “no proof (证据) of human-to-human infection (传染)” of bird flu, the big fear is that the disease could combine with a human flu virus (病毒) to produce a deadly new disease that will kill millions of people across the world. Many Asian farmers live closely with their animals and sell live chickens in the market. This greatly increases the chance of humans being infected with bird flu.

A spokesman of the WHO said that Asian countries having bird flu should introduce a more healthy way of raising and selling chickens. The people there have to completely change their way of life and manners towards animals. Here are some safety measures for people to stay healthy;

* Keep fit through usual exercise;

* Avoid infected poultry and infected people;

* Avoid eating uncooked or under-done poultry and eggs;

* Make sure there is always fresh air in your home;

* Cover your mouth and nose when coughing or sneezing;

* Wash your hands as often as possible.

1.What does the underlined word “poultry” mean?

A. Wild birds.

B. Wild animals.

C. Home-raised birds.

D. Home-raised animals.

2.From the passage, we learn that __________.

A. infected poultry within 3 km was killed in China

B. the first bird flu case was proved in China on Jan. 27

C. human infected cases were found in 11 Asian countries

D. over two thirds of China have been affected by the bird flu

3. What do people fear most?

A. Poultry will infect many people.

B. There will be human-to-human infection.

C. The disease can spread quickly among people.

D. A new disease combining bird flu and a human flu will break out.
