Where do you keep ice? In die freezer, of course. That's what scientists might have thought when they were looking for a safe place to store ice from mountain glaciers from around the world. They’ve decided to store ice in Antarctica because global warming is causing some of the glaciers in places like the Alps to melt.

Jerome Chappellaz of the French National Centre for Scientific Research is involved in creating an ice vault (地下室）there. He says: “We are probably the only scientific community whose sample (樣本) is in danger of disappearing from the face of the planet. If you work on rocks or on tree rings, the raw material is still here and will be for many centuries."

And why do scientists need to study ice from the Alps, for example? Ice formed on the top of a mountain is made of snow accumulated over thousands of years. Trapped air bubbles (氣泡) contain samples of the atmosphere that existed when that ice was formed. Ice is a record of climate By examining ice. we know carbon dioxide in the atmosphere is higher now than in the last three million years. Researchers use this kind of data to build computer models and try to predict what might happen in the future.

The ice vault will be housed in a snow cave at the Concordia Research Station, which is operated by scientists from France and Italy. The ice samples will be sealed in bags and placed 10 meters below the surface. at a constant temperature of -50*C. This will put the scientists’ minds at rest. Losing the ice samples would be a disaster, and nobody wants to see a mine of scientific knowledge lost forever in a giant pool.

1.What makes Antarctica a safe place to store ice?

C. The abundant ice samples there.

D. The absence of global warming.

2.Jerome compares ice with rocks and tree rings to state that_ .

Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you’re unsatisfied, the issue is not a lack of means(方式) to meet your desires but a lack of desires — not that you cannot satisfy your tastes but that you don’t have enough tastes.

Real riches consist of well-developed and hearty capacities(能力) to enjoy life. Most people are already swamped(淹沒) with things. They eat, wear, go and talk too much. They live in too big a house with too many rooms, yet their house of life is a hut.

Your house of life ought to be a mansion(豪宅) , a royal palace. Every new taste, every additional interest, every fresh enthusiasm(熱心,熱情) adds a room. Here are several rooms your house of life should have.

Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of hamburgers and eggs when you’re hungry.

Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but someone who likes a library.

Music like Mozart’s and Bach’s shouldn’t be absent. Real riches are of the spirit. And when you’ve brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills.

Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the bad days, if you could, and did, played a bit.

Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding.

1.The underlined sentence in the second paragraph probably implies that ________.

A. though materially rich, they never seem to be satisfied

B. though materially rich, they remain spiritually poor

C. though their house is big, they prefer a simple life

D. though their house is big, it seems to be a cage

2.It can be learned from the passage that ________.

A. more money brings more happiness

B. art is needed to make your house beautiful

C. literature can enrich your spiritual life

D. sports contribute mainly to your physical fitness

3.What would be the best title for the passage?

A. Interest and Enthusiasm

B. Secret of Wealth

C. Rest and Refreshment

D. House of Life

科目：高中英語 來源：2015-2016學(xué)年黑龍江雙鴨山一中高二下期中考試英語卷（解析版） 題型：閱讀理解

Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer?

People have been wondering why elephants do not develop cancer, even though they have life spans（壽命）that are similar to humans, living for around 50 to 70 years.

Now scientists believe they know why. A team at the University of Chicago, Us has found that elephants carry a large number of genes that stop tumors（腫瘤）from developing. To be precise, they found 20 copies of an anti-tumor gene called TP 53 in elephants. Most other species, humans included, only carry one copy.

According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal’s sensitivity to DNA damage. This lets the cells（細(xì)胞）quickly kill themselves when damaged before they can form deadly tumors.

“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals,” study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous, large creatures with long life spans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.

This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto’s paradox”. Evolutionary biologists believe it results from larger animals using protection that many smaller do not, In the elephant’s case, the making of TP53 is nature’s way of keeping this species alive.

The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.

“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.

“It’s up to us to learn how different animals tackle（對付）the problem so we can use those strategies to prevent cancer in people.”

1.Why are elephants unlikely to develop cancer?

A. They have a large body size

B. They carry many genes that keep tumors from developing

C. Certain genes in their body kill existing tumors

D. Their genes suffer no DNA damage

2.According to Dr. Vincent Lynch, what has been a risk in the evolution of large animals?

A. Extreme weather B. Cells killing themselves

C. Human behavior D. A risk of deadly tumors

3.What does the underlined expression “this phenomenon” on the sixth paragraph refer to?

A. The risk of cancer is not related to body size

B. Larger animals have protection from TP53

C. Larger animals suffer the same risk of cancer as smaller ones do

D. The larger animals are, the bigger risk of cancer they have

4.We can conclude from the last three paragraphs that .

A. depending on nature is not enough to fight against cancer

B. the TP53 genes have proven useful in stopping cancer in mice

C. this new treatment is more effective than the present ones

D. humans are expected to stop cancer in the near future

A great Loss-Shirley Temple dies at 85

February 12,2014

BY DERRIK J. lANG, Associated Press

Shirley Temple Black, who died on February 10th at age 85,wasn’t just a child star. She was THE child star—the sweet little girl whose shining smile helped illumine some of the darkest days the US has known during the Great Depression.

It’s hard today to imagine the super star Shirley was once “America’s Little Darling”. She sang and danced her way to the top of the box office in such films as Bright Eyes, Curly Top and Heidi. By 1940, she had appeared in 43 films. Temple teamed with Bill Robison in four movies, and their dance on the stairs in The Little Colon is still a legendary film moment.

In the 1930s, her name on a movie introduction assured (保證) a packed house. She inspired dolls, dresses, dishes—even a drink (alcohol-free, of course).

US President Franklin D. Roosevelt once famously said that “as long as our country has Shirley Temple, we will be all right.”

Unlike so many of today’s child stars, Temple didn’t end up with her name appearing across the headlines for bad behaviors. Instead of getting her photos on front pages or struggling with drugs and alcohol, Temple went on to a second career in diplomacy (外交) , including presidential appointments as ambassador to Ghana.

She surprised a lot of people who doubted her with her grace, knowledge and eagerness to serve. In fact, her career in public service (20 years) was longer than her career in movies (19). The role she valued most, however, was as wife, mother, grandmother and great-grandmother.

The world has lost a treasured Hollywood legend. But her movies will allow that little dynamic figure to continue charming audiences for a very long time.

1.The word “illumine” in Paragraph l means ________.

A. shorten B. sweeten

C. strengthen D. brighten

2.Temple, as a child movie star, can best be described as ________.

A. sweet and lively B. gentle and kind

C. smart and knowledgeable D. shy and attractive

3.What part did she regard as the most important in her life?

A. A top movie star. B. A businesswoman.

C. Her family role. D. Her diplomacy career.

4.Where does this passage possibly come from?

A. A biography. B. A newspaper.

C. A magazine. D. A poster.
