When the natural climate changes due to global warming,it can surely affect seals.The majority of them live in the Antarctic region so as the ice is melting,their natural habitat can be seriously affected.These changes don’t take place overnight.They can be the result of many years of additional temperatures in the area.The seals then have to find ways to adapt.
Seals depend on the cool air currents to bring plenty of food for them.When the temperature get higher there is less and less food and the seal population starts to shrink.Mothers aren’t healthy enough to feed their babies.Many of them end up abandoned as the mothers have to leave to find their own source of food.
The fact that their desire to produce young can be changed by the warmer temperature is frightening too.It is also believed that the warmer temperature can allow different diseases and viruses to attack the seals.This is a huge concern as they can rapidly wipe out huge numbers of seals out there.
However,these changes in climate and temperature aren’t all bad for other species of seals.Scientists have found that those living in warmer climates are producing more young due to the changes.Research also shows that the females are moving further to find food and water.When they are out of the reach of the governing males,they are more willing to accept the moves of other males in the group.
This is good news too because it means that there will be more selection in the gene pool(基因库)for future generations.It can help the seals as a species adapt to changes in their natural environment more easily.
The climate change problem for seals is directly linked to humans.When we take action to change what we let out into the environment,we will make positive changes for the seals.However,it is going to take a very long time to reverse (彻底改变)the effects of what has already been done.
1.What does the author regard climate changes for seals as
A.A double-edged sword.
B.An unavoidable disaster for existence.
C.A mirror of evolution.
D.A requirement for more choice in the gene pool.
2.What will happen to the seals in warmer climates
A.Their number will be on the increase.
B.The female seals will be in the lead.
C.Their genes will change a great deal.
D.The females will keep away from the males.
3.Which of the following can be the best title for the text

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,

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.

The words “protect animals” appear everywhere in books and on screens,because some animals are even in danger of dying out.But sometimes the reality can be a little different from what people read or watch.
About 300 black bears were killed in Florida,the US,in October,2015.It’s been the first bear hunt in the state since 1994.Local officers explained that the black bear population had grown to 3,500 and become a menace to local people.In the past two years,bears have hurt at least four people in Florida.
Months ago,the Swiss government allowed locals to kill a wolf.This was because the wolf killed 38 sheep,and it was a great loss to some local farmers.Days ago in China,three old men were caught by the police for killing a serow (鬣羚),a kind of protected animal.They said they killed the animal because it ate the plants they grew.
However,these stories don’t always mean that animal protection stops because of human interests especially when it is related to economic development.A man named Zhou Weisen set up a wild animal base in Guilin,Guangxi.He saved over 170 tigers and about 300 bears.His base also offered jobs to local people.
“There may never be a standard answer to the question of whether we should give more attention to the environment or human development,” said Robert May,a British expert at Oxford University.“But we shouldn’t push either one to the side,as the future is uncertain.”
1.What does the underlined word “menace” in the second paragraph mean
A.Threat.
B.Chance.
C.Bargain.
D.Treasure.
2.What does the author intend to tell us by mentioning Zhou Weisen’s story
A.Protecting animals needs hard work.
B.Zhou was good at feeding wild animals.
C.Zhou had a good relationship with local people.
D.Protecting animals can bring economic development.
3.Which of the following statements might Robert May agree with
A.Human development should be considered first.
B.We should pay more attention to animal protection.
C.We should consider both the environment and human interests.
D.It’s difficult to find proper ways to solve environmental problems.

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 honor sits 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.
