【题目】Charles Babbage was born on 26 December 1791, probably in London, the son of a banker. By the time he went to Cambridge University in 1810 he was very interested in mathematics.

In 1812, Babbage and several other friends formed theAnalytical Society. As a student, he was also a member of other societies such asThe Ghost Club, concerned with finding out supernatural phenomena (超自然现象), and the Extractors Club, devoted to freeing its members from the madhouse(精神病院), should any be placed in one.

After graduation Babbage was hired by the Royal Institution to lecture on calculus(微积分). Within two years he had been elected a member of the Royal Society and, with his Cambridge friends, succeeded in setting up the Astronomical Society in 1820, the first to challenge the influence and power of the Royal Society. From 1828 to 1839, Babbage was Lucasian Professor of Mathematics at Cambridge.

The 1820s saw Babbage work on his 'Difference Engine', a machine which could perform mathematical calculations. At the beginning a six-wheeled model was constructed. He then developed plans for a bigger, better, machine - Difference Engine 2. He also worked on another invention, the more complex Analytical Engine, on which his fame as a computer pioneer now largely rests. It was designed to be able to perform any arithmetical calculation using punched(打孔的) cards that would take the instructions, as well as a memory unit to store numbers and many other most important parts of today's computers. But neither the Analytical Engine nor Difference Engine 2 was finished in Babbage's lifetime.

Babbage also worked in the fields of philosophy and code-breaking. He died at his home in London on 18 October 1871.

1What did the Extractors Club aim to do?

A. Help treat its members with mental illness. B. Rescue its members trapped in the madhouse.

C. Set free the patients in the madhouse. D. Place the sick members in the madhouse.

2After he graduated from Cambridge, Charles Babbage _________.

A. was elected to the Royal Society B. became professor at Cambridge

C. founded the Astronomical Society D. taught in the Royal Institution

3What made Charles Babbage remembered as a computer pioneer?

A. Difference Engine. B. Difference Engine 2.

C. The Analytical Engine. D. A memory unit.

4Which of the following best describes Charles Babbage?

A. Active and versatile (多才多艺的). B. Humorous and devoted.

C. Stubborn and generous. D. Bright and selfless.

【题目】In the hills outside Missoula, Montana, wildlife biologists are looking at how climate change affects something very small: the snowshoe hare.

Life for snowshoe hares is pretty stressful almost everything in the forest wants to eat them.

Alex Kumar, a graduate student at the University of Montana, lists the animals that are hungry for hares. “Lynx, foxes, coyotes, […. even] red squirrels.”

Kumar and field technician Tucker Seitz spend months searching these woods for hares, often listening for signals from hares they've already put radio collars on.

They catch other hares with wire traps about the size of a breadbox, with some apple as bait (诱饵). Most of the hares they track live less than a year — a hazard (风险)of being what Kumar calls “the cheeseburger of the ecosystem”.

But snowshoe hares have a special skill: camouflage. They're brown during the summer, but turn white for the snowy winter months.

“There’s times when you’re tracking them and you know they’re really, really dose, and you just can’t find them,” he says.

Hares switch color in the spring and fall in response to light, when the days get longer or shorter. But if the snow comes late, you get a white hare on brown ground.

“And they really think that they’re camouflaged,” Kumar says. “They act like we can’t see them.”

Kumar calls this “mismatching,” and it's becoming more of a concern with climate change.

“If the hares are consistently molting (脱毛) at the same time, year after year, and the snowfall comes later and melts earlier, there’s going to be more and more times when hares are mismatched,” he says.

Scott Mills of North Carolina State University leads the research. He says they're finding that mismatched hares die at higher rates. That’s a concern for the threatened Canada lynx, which mainly eats these hares.

“It’s a very clear connection to a single climate change stressor,” Mills says.

Hares might be able to adapt over time. Some snowshoe hares in Washington State don't turn white at all. Mills is trying to figure out whether hares and other wildlife can adapt as fast as the climate is changing.

“But how fast is too fast?” he asks.

1The word “camouflage”(Paragraph 6) is closest in meaning to .

A. escaping B. hiding

C. fighting D. scaring

2According to the passage, snowshoe hares can now be easily discovered by their enemies because they .

A. change their fur color to white too late

B. haven’t adapted to climate change

C. can no longer adapt to the change of light in spring and fall

D. find it more and more difficult to molt at the same time each year

3Which best describes Mills' tone in the passage?

A. Approving. B. Enthusiastic.

C. Concerned. D. Doubtful.

【题目】Failure means the beginning of something new. It opens yourself to new opportunities. 1As a matter of fact, sometimes it helps people realize the right thing to do.

2 Failing at something is not the end of the world. In fact, it is more like a warning to re-think about your decisions. It is important that we all fail sometimes in order to strengthen ourselves.

Failing at something often brings new experiences and opportunities that can improve you at whatever you failed at. 3Knowing well the situation you are in is the basis of your future success. Having another opportunity at something can be important in life when trying to reach your goals or to accomplish something important to you.

We have all learned new skills in life and we learned them only after first failing to do them properly. 4However, we are all humans and it is human nature to hate failure. I think it is especially difficulty for us as teenagers. Somehow, because we are getting older, we feel we should learn more quickly and succeed more quickly than we did when we were younger. Failure is the most natural thing on the way towards achievements. 5.

The opportunities brought on from failure are usually more rewarding than actually succeeding in the first place. Failure isn’t always something to fear or to avoid. In lots of cases failure provides a greater chance to learn the right way.

A. We know this is true.

B. Failure isn’t always bad.

C. Failure can be avoided in some cases.

D. Failing helps you realize the reality.

E. A fear of failure is likely to lead to pressure.

F. Failure helps you adjust your plans.

G. It should be seen as a step on the road to success.
