题目内容

Antarctica is the southernmost place on Earth, and it is larger than the United Sates and 95% of it is covered with ice. The ice is 5 kilometers thick at places and it never melts. At least that is what we thought, but let us keep it that way for now.

The ice seems to be alive as it works its way towards the seA． It forms an ice shelf over the water. The edge breaks away from the shelf and falls into the seA． From here it drifts. Now big pieces of ice become icebergs that can be 160 km long. They now drift north until they finally melt and become part of the ocean. This process is part of a bigger process which in turn forms a cooling system for Earth. This is so important that no country is allowed to control this areA． The treaty (agreement) signed by 12 countries at first and later joined by more, was to prevent any country harming the planet with irresponsible behavior.

The treaty basically states that:

Antarctica can be used for peaceful purposes only.

No country may build a military base there.

No country may do a nuclear test there.

No country may dump nuclear waste there.

Scientists working there will share their information.

Some other rules are there to protect the penguins and seals.

No dogs may run loose.

No planes may land near large groups of animals.

No guns, explosives, or tractors may be used near the animals.

Most important is that every member can inspect any of the other bases if he suspects that the treaty rules are being broken.

While the treaty is not foolproof（万无一失的）, it does play a very important part in the protection of AntarcticA． The more people realize the effects that pollution has on this continent, the bigger the pressure will be on Governments to change the way they look at pollution.

69．Why was it important to sign a treaty for Antarctica?

A．Because the ice on Antarctica will finally melt into the ocean.

B．Because Antarctica is covered with 5 kilometers thick ice.

C．Because Antarctica balances the temperature of Earth.

D．Because there are many big icebergs in AntarcticA．

70．What is the process of the movement of ice in Antarctica?

A．Ice shelf---sea water---iceberg---ice.

B．Sea water---ice---iceberg---ice shelf.

C．Iceberg---ice shelf---ice---sea water.

D．Ice---ice shelf---iceberg---sea water.

71．What is included in the Antarctica treaty?

A．There is no secret research information in AntarcticA．

B．Dogs are not allowed to be raised in AntarcticA．

C．Waste can’t be thrown away in AntarcticA．

D．People can’t bring their guns to AntarcticA．

A
Short and shy, Ben saunders was the last kid in his class picked for any sports team. “Football, tennis, cricket---anything with a round ball, I was useless,” he says now with a laugh. But back then he was the object of jokes in school gym classes in England’s rural Devonshire.
It was a mountain bike he received for his 15th birthday that changed him. At first the teen went biking alone in a nearby forest. Then he began to cycle along with a runner friend. Gradually, Saunders set his mind on building up his body, increasing his speed, strength and endurance. At age 18, he ran his first marathon.
The following year, he met John Ridgway, who became famous in the 1960s for rowing an open boat across the Atlantic Ocean. Saunders was hired as an instructor at Ridgway’s School of Adventure in Scotland, where he learned about the older man’s cold-water exploits(成就). Intrigued, Saunders read all he could about Arctic explorers and North Pole expeditions, then decided that this would be his future.
Journeys to the Pole aren’t the usual holidays for British country boys, and many people dismissed his dream as fantasy. John Ridway was one of the few who didn’t say, “You’re completely crazy,” Saunders says.
In 2001, after becoming a skilled skier, Saunders started his first long-distance expedition toward the North Pole. He suffered frostbite, had a close encounter(遭遇) with a polar bear and pushed his body to the limit.
Saunders has since become the youngest person to ski alone to the North Pole, and he’s skied more of the Arctic by himself than any other Briton. His old playmates would not believe the transformation.
This October, Saunders, 27, heads south to explore from the coast of Antarctica to the South Pole and back, an 1800-mile journey that has never been completed on skis.
46. The turning point in Saunders’ life came when________.
A. he started to play ball games
B. he got a mountain bike at age 15
C. he ran his first marathon at age 18
D. he started to receive Ridgway’s training
47. We can learn from the text that Ridgway_________.
A. dismissed Saunders’ dream as fantasy
B. built up his body together with Saunders
C. hired Saunders for his cold-water experience
D. won his fame for his voyage across the Atlantic
48. What do we know about Saunders?
A. He once worked at a school in Scotland.
B. He followed Ridgway to explore the North Pole.
C. He was chosen for the school sports team as a kid.
D. He was the first Briton to ski alone to the North Pole.
49. The underlined word “Intrigued” in the third paragraph probably means______.
A. excited B. convinced C. delighted D. fascinated
50. It can be inferred that Saunders’ journey to the North Pole _______.
A. was accompanied by his old playmates
B. set a record in the North Pole expedition
C. was supported by other Antarctic explorers
D. made him well-known in the 1960s

I recently spent two years in the Arctic filming the series Blue Planet. I love being in an environment that hasn't changed for 20,000 years. Of course it's freezing, but it must be a healthy place because you never catch colds.
When I'm filming, I like to really feel how lonely the environment is. Filming underwater involves cutting through thick ice and diving in tied to a line. The person at the other end has to be ready to pull you out fast if necessary.
Originally I was a research diver for the British Antarctic Survey project, but for me science lacked excitement. I'd always enjoyed photography, and whenever camera teams passed through, they encouraged me to watch and learn. I was then able to move into filming in 1985 and have concentrated on Arctic and Antarctic wildlife ever since.
I prefer to be faced with the animals I'm filming. I haven't got in the water with killer whales yet, but I plan to. Of course, it's dangerous if you choose the wrong moment. They're big animals and can move fast, so I'd be stupid to film them searching for food!
I've never had problems with polar bears, although once I was frightened when one tried to get into my tent. Polar bears are bold, clever and dangerous. But I made this one see I wasn't about to attack it - I'm sure it realised I wouldn't hurt it.
When I come home back from my trips, I work in the mornings and spend the afternoons swimming to keep fit. Now I'm fifty, filming is harder. The challenge for me is to continue to deliver high-quality work.
56. In this text, the writer is describing __________.
A. the challenges of the environment he works in B. the beautiful scenery of the Arctic

A. He was bored by working only in Antarctic.
B. It taught him how to become a skilled diver.
C. He wasted the years he spent as a scientist.
D. It provided him with a chance to learn about filming.
58. When talking about killer whales, the writer says that __________.
A. he has always been careful when diving with them
B. he tries to avoid any danger by facing them
C. he will only film them from a safe distance
D. he believes there are safe opportunities to film them
59. How does the writer describe his experience with a polar bear?
A. The writer realized he was wrong to trust polar bears.
B. The writer felt nervous that the bear might come back.
C. The bear seemed to know the writer wasn’t a danger.

第二部分：阅读理解（20小题, 每小题2分，满分40分）

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

A New Zealand fishermen caught what may prove to be a world-record-breaking colossal squid(鱿鱼).

In the cold, dark waters of the Antarctic hides a creature with eight arms, two super long tentacles(触须) and eyes as big as dinner plates. Sound like something out of a science fiction movie? Think again.

On February 21, New Zealand fishermen landed a colossal squid the length of a school bus. They had been fishing with long lines for Chilean sea bass in the waters off the coast of New Zealand when they caught the rare squid. With two hours of hard work, the crew skillfully pulled the creature into a net and dragged in aboard their ship.

Scientists evaluate that the animal weighs about a half ton and is about 40 feet long. That would make this colossal squid the biggest on record.

First identified in 1925 after two tentacles were found in a whale’s stomach, the colossal squid has long been a mystery. The animals are not easy to observe because they can go down to ocean depths of 6,500 feet. What scientists do know from studying the bodies of a half dozen colossal squids is that they are fierce hunters.

The recently captured colossal squid has been frozen to keep it for scientific study. It will be transported to New Zealand’s national museum, Te Papa, in the capital city of Wellington. Experts believe it to be the first adult male ever caught undamaged. Scientists hope to learn more about the colossal squid’s diet, behavior and reproductive(繁殖)patterns.

“Scientists will be very interested in this amazing creature, ”said New Zealand Fisheries Minister Jim Anderson. “It adds immeasurably to our understanding of the marine environment. ”

1. Why is it usually difficult for experts to observe the squid?

A. Because it moves too fast B. Because it is too large.

C. Because it is dangerous. D. Because it can go down to deep ocean.

2. What can be inferred from the passage?

A. The squid is from a science fiction story

B. The fishermen often meet colossal squids

C. Scientists know much about the colossal squid.

D. The fishermen had some difficulty catching the large squid.

3. What’s the purpose of catching such a huge squid?

A. To make it into food B. To set a world record

C. To do research on it D. To display it for visitors

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

A. The biggest squid ever found B. Scientific research on squid

C. The lifestyle of the colossal squid D. How the fishermen caught the squid

Later, these rocks proved that ___ in the distant past the Antarctic was covered by plants.

A．at one time

B．at a time

C．at times

D．at the same time
