1、阅读下列短文,从每题所给的 A、B、C、D四个选项中选出最佳选项。
Deep below the ground, radioactive elements break up water molecules(分子), producing substances that can fuel subsurface life. This process, known as radiolysis(辐射分解),has supported bacteria in tiny cracks filled with water on Earth for millions to billions of years. Now a study published in Astrobiology shows that radiolysis may have supported life in the Martian subsurface.
Dust storms, rays in the universe and solar winds ruin the Red Planet's surface. But below, some life might find shelter. "The best survival habitat on Mars is the subsurface," said Jesse Tarnas, a planetary scientist at NASA, Examining the Martian underground could help scientists learn whether life existed there. And the best subsurface samples available today are Martian meteorites(陨石) that have crash-landed on Earth.
Tarnas and his colleague looked at the minerals on the Martian surface and how many radioactive elements there were, using satellite and rover data, They used computers to simulate(模拟) radiolysis to see how efficiently the process would have generated life-supporting hydrogen gas and other chemical substances. They reported that if water was present, radiolysis could have supported life for billions of years and perhaps still could today.
Scientists had previously studied Mars radiolysis, but this marked the first estimate using Martian rocks to see how habitable Mars underground might be. Tarnas and his colleagues also evaluated the potential richness of life in Martian underground.They found that up to a million bacteria could exist.in just one kilogram of rock, The most habitable seemed to be the southern highlands of Mars, which is the most ancient area on Mars, according to Tarnas.
"Underground life would require water and it remains unknown if groundwater exists on the planet," says Lujendra Ojha, a planetary scientist at Rutgers University. Determining whether the Martian, subsurface contains water. will be an important next step, but this investigation helps to motivate that search, Ojha says, "Where there is groundwater, there could be life."

D、The process of radioactive elements splitting water molecule(2)、 How did Tarnas and his colleague carry out their research?A、By simulating with collected data. B、By comparing original data.

2、阅读下列短文,从每题所给的 A、B、C、D四个选项中选出最佳选项。
I am asked repeatedly why anyone would want to keep an "'ugly" building or a building that is dirty and clearly in need of work, I guess you could say we preservationists (文物保护者)look at buildings through a different angle - an angle that can see the swan in the ugly duck the story in the simple lines, and the book behind the cover.
The Queen Emma Building is remembered by many as one of the ugliest buildings in town. Yet the angle from which a preservationist views the building is that it is uniquely constructed with an artistical sun shield to block the sunlight, a decorative wall designers used concrete bricks to form. Unfortunately, it was removed in 20il, making the building one of many contemporary buildings in town.
Other times, when a beautiful site is replaced by a "horrible" building, people hate it and can't get over their anger, even when that: "horrible" building becomes an important part of our story. This is particularly true in San Francisco with many Victorian buildings, which are many preservationists' favorite. Yes, it was a tragedy, that many Victorian buildings got torn down several decades ago, but those losses also tell another important story. It tells the story of the1950s and 1960s when there was hope for a more equal society with in expensive housing for the working class. Should that history be wiped from our memories?
Preservation is not just about keeping pretty, well-kept buildings, but about holding on to parts of our history - not just the history of huge events, but the story of how everyone used to go to a certain corner market. Our history cannot be told only in buildings that meet someone's criteria of beauty, sometimes our history is, painful, but no less important.
(1)、Which section might the passage come from?A、Opinion and Views. B、Health and Wellbeing C、Space and Exploration. D、Business and Finance.(2)、How does the author feel about removing the sun shield of the Queen Emma Building?A、It's incredible. B、It's regrettable. C、It's inspiring D、It's entertaining.(3)、Why were many Victorian buildings in San Francisco torn down?A、To wipe the history of the Victorian era. B、To make land available for cheap housing. C、To ease the deep anger of the working class. D、To revive the architecture of the Victorian era.(4)、What is the author's purpose in writing this passage?A、To analyze the role of preservationists. B、To introduce buildings with historical value. C、To explain why architects make ugly buildings D、To stress the significance of preserving "ugly" buildings. -
3、阅读下列短文,从每题所给的 A、B、C、D四个选项中选出最佳选项。
Despite extreme cold, cruel ice and being brushed off as mad, Slovenian Davo kamicar became the first person to ski non-stop down Mount Everest. After a dramatic fall over almost sheer cliffs of snow, stones and ice, 38-year-old Kamicar returned to his base camp after five hours of skiing. "I feel only absolute happiness and absolute tiredness," he said.
Due to the severe weather conditions, Kamicar flung himself back down the mountain as soon as he reached the top rather than have a rest as planned At one point, he had to speed overstretches of ice that collapsed and broke underneath him and could have sent him falling into the deep crevasses(裂缝) that dot the mountain.
The descent (下落) had been widely regarded as extremely dangerous. The Darwin Awards website, known for documenting foolhardy deaths, urged people to log on to their website and "keep your eyes peeled for a live Darwin Award". However, the only body to make the news was the corpse (尸体)of an unknown mountaineer which Kamicar zipped past as he descended one of an estimated 120 corpses, thought to litter the slopes." This mountain is always full of surprises. Seeing a dead man out there was still a shocking experience," he said.
Thanks to strategically placed cameras on the mountain and one attached to his safety helmet hundreds of thousands of people witnessed the process online, which was one of the record highs ever of more than 650,000 hits. The website was once jammed as people tried to access the site.
A previous failed attempt had already cost Kamicar two fingers when he got frostbite as a fierce storm hit the peak. Coming from a skiing family and had his first Himalayan skiing expedition in 1989, he has been ever since tireless in raising funds and sponsorship for more expeditions, with Everest as the permanent goal.

C、The unexpected collapse of an icy hillside. D、The sight of 120 corpses littering the slopes.(4)、Which of the following may be the best title for the passage?A、Darwin Award for Survivors B、Body of Mountaineer Found on Everest C、Mad Man Skis down Everest D、Extreme Sports Hero Slides to a Record -

A Tale of Highly Unusual Magic
Genre: Fantasy
Number of Pages: 320
What's the basic story line?
Kai and Leila have never met, but their seemingly dull lives will be drawn together in unbelievable ways. Each girl is vacationing—Kai in Texas and Leila in Pakistan. Each girl finds a copy of a book called The Exquisite Corpse. Each book is blank, but when Kai writes a sentence, the book magically begins a story. When either girl writes another phrase, the book shows more. Whatever the girls are doing when they write—getting attacked by a dog, hunting for a rare species, accidentally buying a goat—helps to develop the plot of The Exquisite Corpse. It also makes reading A Tale of Highly Unusual Magic even more enjoyable.
Are the characters believable? Many aspects of the characters are realistic. Readers see that the characters, like all of us, can sometimes fail. Also, both characters have some unflattering (不讨人喜欢的) qualities, even though they're represented as "the good guys" in the story.
Who would like this book? Any lover of fantasy and stories about magic would enjoy this book. Readers who enjoy knowing things the characters don't, or who like being shocked by a huge plot twist (曲折的情节),will like this book.
On a scale of 1 to 10, how would you rate this book? I would rate A Tale of Highly Unusual Magic a perfect 10, because of the creative story idea and the crazy plot twists that keep the reader turning page after page. I, for one, did not want the story to end.
