Passage 6

(福建省厦门外国语学校2009届高三最后一次模拟B篇)

Do you want to see the effects of global warming? Then head north. Recent studies indicate that the North Pole could be underwater during the summer in less than 10 years, instead of coated in thick sea ice. But seeing the Arctic terrain (地带) up close isn’t easy, unless you’re handy with a dogsled. Steger is going to take all of us there.

Steger, 64, is a great polar explorer. He was the first person to make a dogsled trip to the North Pole, and is also a devoted environmentalist who was early to ring the alarm bell on global warming.

Steger is about to lead a team of six young adventurers on a 1, 400-mile, 60-day-long dogsled trip across Ellesmere Island, in the Canadian Arctic. The sea ice in that region should still be frozen. “We want to take our audience to the front lines of global warming, ” says Steger. The team will be uploading videos, as they march along, allowing armchair adventurers and kids in classrooms to follow their progress day to day.

Steger’s team will include some already-famous young explorers. Sam Branson, 22-year old, is an experienced Arctic traveler. Also on the journey will be 27-year-old Norwegian Sigrid Ekran. Last year Ekran become only the second woman in history to win Rookie (新秀) of the Year for the Iditarod Sled Dog Race.

What they will see may be surprising. Even Steger doesn’t know exactly what to expect. Climate change has already reshaped the geography of the Arctic. “Within a decade or less, it’s going to be impossible to reach the North Pole by dog team, without flotation (漂浮), ”says Steger.

Passage 5

(福建省厦门双十中学09届高三热身考试D篇)

Alone in the wilderness. Nothing but jungle. A world of shadow with the rays of light falling like blonde hair from the crowns of the giant trees. Jungle in the midday sun. Everything motionless. Not a sound from sky or earth. Complete silence. Only some coconuts falling, at long intervals, very far away. The world reduced to the soft touch of cool grass along my naked back, and a sweet smell of rich soil and vegetation. Stretched out with closed eyes beside my heavy burden of fruit and firewood, I enjoyed the feeling of fresh blood streaming through every part of my body and fresh jungle air filling every corner of my lungs.

   Resting motionless, I could see the sun through my closed eyelids, alone in the sky, as lonely as I, and as motionless and silent as everything else. The earth had surely stopped turning and somewhere on this planet there was supposed to be roaring traffic in busy streets. What a crazy, unbelievable thought!

    Another coconut fell, to make the world come to a complete standstill. I had to roll over onto my stomach to feel that at least I could move and make noises. Then I found company. A little brown ant was struggling to find its way with a bit of dry straw through the jungle of leaves and grass below my nose. I wondered if I could give the little fellow a lift with its burden, but it showed not the slightest sign of tiredness and struggled on with all six legs, head first or head last, waving its feelers energetically as if the trip had just started. Who ever saw a tired ant? Tiredness, disagreeable tiredness, is restricted to hunted animals, slaves and modern man. It is as great an effort for an office clerk to walk five blocks with a loaded brief-case as it is for a jungle-dweller to cross a valley with a goat on his back. It is as hard to get up and climb or run when you have been seated for years as it is to get up and walk when you have been in bed for months. The body is strange. Spare it, and you get really tired for almost nothing; use it, and almost nothing makes you really tired.

    I rose to my feet. I had heard a horse neighing down in the valley. Above me, on the open highland plains, there were wild horses. But down in the valley there was never a horse unless there was a man on it. Somebody was making his way up the valley and my wife was alone.

68. There are more than two thousand species of plants    .

A. that exist only in this area          B. that will be harmed by the changing weather

C. that will survive in this area       D. that will die out in future

答案  65.D  66.A  67.C  68.A

Passage 4

(安徽省马鞍山二中2009届高三第四次模拟考试D篇)

With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.

Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct(灭绝), Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2, 000 species of mammals, birds and reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant(移植) the embryo into a host animal.

The entire procedure(程序) could take from three to five years to complete.

“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
