第二部分 阅读理解(共两节，满分40分)
第一节(共15小题；每小题2分，满分30分)
阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
We already know the fastest, least expensive way to slow down climate change—use less energy.With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.
Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change.Scientists have reported recently that the world is heating up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emission(排放) of carbon dioxide (CO2) and other greenhouse gases that are trapping heat in our atmosphere.
We decided to try an experiment.For one month we recorded our personal emission of CO2.We wanted to see how much we could cut back, so we went on a strict diet.The average US household produces about 150 pounds of CO2 a day by doing common things like turning on air conditioning or driving cars.That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses.But how much should we try to reduce
For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth.In his book, he had challenged readers to make deep cuts in personal emission to keep the world from reaching extremely important tipping__points,__such as the melting(融化) of the ice sheets in Greenland or West Antarctica.“To stay below that point, we need to reduce CO2 emission by 80 percent，”he said.
Good advice, I thought.I’d opened our bedroom windows to let the wind in.We’d gotten so used to keeping our air conditioning going around the clock.I’d almost forgotten the windows even opened.We should not let this happen again.It’s time for us to change our habits if necessary.
1．Why did the author and his wife try a new diet
A．To take special kinds of food.
B．To respond to climate change.
C．To lose weight.
D．To improve their health.
2．The underlined words “tipping points” most probably refer to “________”．

A．made deep cuts in his personal emission of CO2
B．wrote a book about the climate changes
C．succeeded in reducing CO2 emission by 80 percent
D．was an author popular among readers
4．Which of the following would be the best title for this passage
A．Saving Energy Starts at Home
B．Changing Our Habits Begins at Work
C．Changing Climate Sounds Reasonable
D．Reducing Emission of CO2 Proves Difficult
B

Unbelievable Stories of Animals Acting Just Like Humans
◆Horses are picky eaters
Horses have an even better sense of smell than humans do.When horses raise their noses and open their nostrils (鼻孔),their nervous system allows them to sense smells we can’t sense.This might explain why they refuse dirty water and carefully move around meadows,eating only the tastiest grasses,experts say.
◆Whale says thanks
In 2011,a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it.Afterward,in an hour-long display of thanks,the whale swam near their boat and leaped into the air about 40 times.
◆Pandas like to be naughty
Is there anything more lovely than a baby panda,except maybe a human baby In fact,baby pandas sometimes behave like human babies.They sleep in the same positions and value their thumbs.Pandas are shy by nature for its shy behaviours such as covering its face with a paw or ducking its head when confronted by a stranger.
◆A cat honors its owner
Paper towels,and a plastic cup are just a few of the gifts that Toldo,a devoted three-year-old gray-and-white cat,has placed on his former owner Iozzelli Renzo’s grave every day since the man died in September 2011.Renzo adopted Toldo from a shelter when the cat was three months old,and the two formed an inseparable bond.After Renzo passed away,Toldo followed the coffin to the cemetery,and now “stands guard” at the grave for hours at a time.
13.Which of the following acts like a human baby according to the passage
A.The whale.
B.The cat.
C.The horse.
D.The panda.

第二节(共5小题；每小题2分，满分10分)
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Some animals see differently than we do.Some animals,like bees,have cones(视锥细胞) for colours we can’t see.Some animals have developed a highly-advanced senses of smell or hearing abilities. 1
The most interesting feature of night animals is the size of their eyes. 2 Some animals have tubular(管状的) eyes as a means of increasing their size.Many night animals cannot move their eyes within the orbit. 3 Owls,for example,can turn their neck through 270° and this aids their vision.
4 It is the tapetum lucidum,meaning “bright carpet(明毯)”,an adaptation for night vision.The tapetum is a thick reflective membrane(膜),15 cells wide,directly beneath the retina.It collects and returns light back to the retina a second time,giving the rods a second chance to absorb the image information,thus making the little light more available to them. 5
Although night animals see mostly imperfect shapes,outlines and no colours,by maximizing their sensitivity to low light levels with the above adaptations,it is enough for them to hunt,feed and survive in the dark of night.
A.Others see things clearly at night.
B.Their large eyes can collect more light.
C.Instead,they have special ability in the neck.
D.It allows the head and eyes to remain motionless.
E.Some animals of the night have got a spherical(球形的) lens.
F.As this light is reflected off the tapetum,they appear to glow.
G.On a dark night,flash a bright light at your dog’s eyes and you notice that their eyes glow in the dark.

第二节 概要写作（25分）
阅读下面短文,根据其内容写一篇60词左右的内容概要。
The largest land animal remaining on the earth,the African elephant is of much importance to African ecosystem.Unlike other animals,the African elephant is to a great extent the builder of its environment.As a giant plant-eater,it significantly shapes the forest-and-savanna(大草原) surroundings in which it lives,therefore deciding the conditions of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it both a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbush,as well as pulls branches off big trees.This results in numerous open spaces in not only deep tropical forests but also the woodlands that cover part of the African savannas.In these open spaces are numerous plants in various stages of growth,which attract a variety of other plant-eaters.
Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants create open spaces,allowing new plants to grow on the forest floor.In such situations,the forest becomes suitable for large-hoofed plant-eaters to move around and for small-sized plant-eaters to obtain their food as well.
Scientists are worried now that the African elephant has become an endangered species.If the elephant dies out,scientists say,many other animals will also disappear from vast areas of forest and savanna,greatly changing and worsening the whole ecosystem.

Dear President,
I’m writing to give some suggestions to further protect the Tibetan antelope.As is often reported,too many Tibetan antelopes are being hunted and killed illegally for their fur,from which the illegal hunters can make great profits.As a result,the number of the Tibetan antelopes is decreasing rapidly from about 1,000,000 in 1990 to less than 100,000 at present.
Immediate measures must be taken to improve the present situation.Firstly,the importance of protecting the Tibetan antelopes should be promoted.Secondly,would you provide more money for the conservation of the Tibetan antelopes Last but not least,I suggest that some volunteers be sent there to help protect the Tibetan antelopes.
These are my suggestions and I hope they could mean something for a better future of the Tibetan antelopes.
Looking forward to your reply.
Yours sincerely,
Li Hua

We already know the fastest, least expensive way to slow down climate change—use less energy.With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.
Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change.Scientists have reported recently that the world is heating up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emission(排放) of carbon dioxide (CO2) and other greenhouse gases that are trapping heat in our atmosphere.

For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth.In his book, he had challenged readers to make deep cuts in personal emission to keep the world from reaching extremely important tipping__points,__such as the melting(融化) of the ice sheets in Greenland or West Antarctica.“To stay below that point, we need to reduce CO2 emission by 80 percent，”he said.
Good advice, I thought.I’d opened our bedroom windows to let the wind in.We’d gotten so used to keeping our air conditioning going around the clock.I’d almost forgotten the windows even opened.We should not let this happen again.It’s time for us to change our habits if necessary.

第二节 概要写作（25分）
阅读下面短文,根据其内容写一篇60词左右的内容概要。
The largest land animal remaining on the earth,the African elephant is of much importance to African ecosystem.Unlike other animals,the African elephant is to a great extent the builder of its environment.As a giant plant-eater,it significantly shapes the forest-and-savanna(大草原) surroundings in which it lives,therefore deciding the conditions of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it both a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbush,as well as pulls branches off big trees.This results in numerous open spaces in not only deep tropical forests but also the woodlands that cover part of the African savannas.In these open spaces are numerous plants in various stages of growth,which attract a variety of other plant-eaters.
Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants create open spaces,allowing new plants to grow on the forest floor.In such situations,the forest becomes suitable for large-hoofed plant-eaters to move around and for small-sized plant-eaters to obtain their food as well.
Scientists are worried now that the African elephant has become an endangered species.If the elephant dies out,scientists say,many other animals will also disappear from vast areas of forest and savanna,greatly changing and worsening the whole ecosystem.

Dear President,
I’m writing to give some suggestions to further protect the Tibetan antelope.As is often reported,too many Tibetan antelopes are being hunted and killed illegally for their fur,from which the illegal hunters can make great profits.As a result,the number of the Tibetan antelopes is decreasing rapidly from about 1,000,000 in 1990 to less than 100,000 at present.
Immediate measures must be taken to improve the present situation.Firstly,the importance of protecting the Tibetan antelopes should be promoted.Secondly,would you provide more money for the conservation of the Tibetan antelopes Last but not least,I suggest that some volunteers be sent there to help protect the Tibetan antelopes.
These are my suggestions and I hope they could mean something for a better future of the Tibetan antelopes.
Looking forward to your reply.
Yours sincerely,
Li Hua
