Many animal and plant species have become extinct and many more are in critical danger.Finding ways to protect the earth's wildlife and conserve the natural world they inhabit(居住)is now more important than ever.
The Dodo is a classic example of how human caused damage to the earth's biology.The flightless Dodo was native to the Island of Mauritius in the Indian Ocean.It lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505.The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the Island by humans such as pigs, monkeys and rats.The population of Dodos rapidly decreased and the last one was killed in 1681.
The Rhino(犀牛)horn is a highly prized item for Asian medicine.This has led to the animal being hunted in its natural habitat.Once widespread in Africa and Eurasia，most Rhinos now live in protected natural parks and reserves(保护区)．Their numbers have rapidly decreased in the last 50 years，and the animals remain under constant threat from poachers(偷袭者)．
The Giant Panda
The future of the World Wildlife Fund's symbol is far from certain.As few as 1，600 pandas remain in the wild.The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison.However，the panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animal's continued existence.
The International Whaling Commission is fighting to ensure the survival of the whale species.Despite the fact that one－third of the world's oceans have been declared the whale sanctuaries(保护区).7 out of 13 whale species remain endangered.Hunted for their rich supply of oil，their numbers have decreased to just 300.Collisions with ships，poisonous pollution and being caught in fishing nets are other major causes of whale deaths.
The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5，000 and 7，000 and The Bali，Javan，and Caspian tigers are already extinct.The South China tiger is precariously close to disappearing，with only 20 to 30 still alive.Like the Rhino horn，tigers' bones and organs are sought after for traditional Chinese medicines.These items are traded illegally along with tiger skins.

George was a game warden(猎物繁殖和保护区的管理员)in Kenya.One day，he found three tiny lions beside a dead lioness.They were so little that their eyes had not yet opened.Sadly，he took the three little lions and drove back home.
When George got out of the car with the baby lions，his wife Joy Adamson immediately took over.Joy had cared for many young animals over the years，but she had never tried to raise baby lions！However，she was determined to save these babies.
The lions grew rapidly.But as the lion grew bigger and stronger，Joy and George realized they could not keep three large lions.They decided to present two of the lions to a zoo；they would keep the smallest lion，which they named Elsa.
Joy and George taught Elsa to hunt and to protect herself.Elsa liked to play with her human friends，but as Elsa grew to her adult size，this play became dangerous.More than once，Elsa knocked Joy to the ground，scratching(抓伤) her.Joy and George both realized that it was time to find Elsa a new home.They knew she needed a wild home where she could live the life she was born to lead.Finally，Joy and George decide to set Elsa free in Meru Park at the foot of Mt Kenya.
Elsa never forgot Joy and George.Whenever they camped nearby，Elsa would come to visit，rubbing her head against their legs in greeting.
Joy missed Elsa，but was happy that she had made a successful life as a wild lion.Joy wrote a book about Elsa，Born Free，which became an international bestseller.Joy travelled all over the world，talking about the importance of saving the wild animals of the world.
Joy lived out her life in Africa，working with wild animals.She wrote more books about her experiences.Her heartfelt interest in animals and her great love for Elsa helped inspire (激发) a worldwide movement to protect wildlife.For Joy Adamson，there was no greater gift than the beauty and spirit of wild animals，living free.

In the past，man did not have to think about the protection of his environment.There were few people on the earth，and natural resources seemed to be unlimited.Today things are different.The world has become too crowded.We are using up our natural resources too quickly，and at the same time we are polluting our environment with dangerous chemicals.If we continue to do this，human life on the earth will not survive.
Everyone realizes today that if too many fish are taken from the sea，there will soon be none left.Yet，with modern fishing methods，more and more fish are caught.We know that if too many trees are cut down，forests will disappear and nothing will grow on the land.Yet，we continue to cut down more and more trees.We realize that if rivers are polluted with waste from factories，we will die.However，in most countries waste is still put into the rivers or the seas and there are few laws to stop this.We know，too，that if the population of the countries is rising at the present rate，in a few years，there will not be enough food.What can we do to solve these problems?
If we eat more vegetables and less meat，there will be more food for everyone.Land that is used to grow crops can feed five times more people than land where animals are kept.
Finally，if we educate people to think about the problems，we shall have a better and cleaner planet in the future.
1.Today we have to think about the protection of our environment because ________．
A. things on our planet are getting worse and worse
B. the limited natural resources are being used quickly
C. the environment is continuing to be polluted by too much waste and poison
D. worse environment is endangering the lives of human beings
2.Which of the following statements is NOT true?

Raising a baby takes a lot of work, especially when that baby is a king penguin. Now, it looks like climate change will make life even harder for these birds.
Most king penguins live on the Crozet Archipelago, a group of islands in the Indian Ocean, about 1，000 miles north of Antarctica. After the penguin chicks are born in November，which is summer in the Southern Hemisphere，both parents spend 4 months collecting fish to feed their offspring (后代)．
When the fish move to deeper waters in March, the adults swim hundreds of miles south. There, near the Antarctic ice, they spend the winter eating seafood to add to their own energy stores. In October, the parents return to their babies and finish raising them.
Scientists from France have been studying king penguins for a decade. Starting in 1998，Yvon Le Maho and his colleagues put electronic ID tags under the skin of hundreds of penguins. These are the same types of tags you might put in your dog or cat so that you can track them if they're lost. The tags have allowed researchers to get everything about penguins, such as how long they live, whether they return from their winter trips, and if their babies manage to survive the winter.
To see whether water temperatures affect the penguins, Le Maho compared his data with temperature records. Ocean surface temperatures vary from year to year. And previous research had shown that fewer fish and other creatures grow when the water is warmer. Le Maho suspected that this drop would make it harder for adult penguins to survive the hard times ahead. Indeed, his results showed that fewer adults survived during winters when the water was especially warm.
King penguins can live for up to 30 years. And for now, the population still appears healthy. But a warming trend could spell big trouble for a bird that depends on cold and ice.

Like most of my schoolmates, I have either brothers nor sisters; in another words, I am an only child. My parents love me dearly of course and will do all they can make sure that I get a good education. They did not want me to do any work at family；they want me to devote all my time to my studies so that I'll get good marks in all my subjects. We may be one family and live under a same roof, but we do not seem to get much time to talk about together. It looks as if my parents treat her as a visitor and a guest. Do they really understand their own daughter? What things are in other homes，I wonder.
What will the city of the future be like? No one knows for sure，and making predictions is a risky business. But one thing is certain about the future city—they are going to get bigger before they get smaller. Here are some of the ideas for running a city of 50,000 people in the year 2025.

2. No smoking will be allowed within a future city's limits.
3. In the future all shopping will be done online, and catalogues will have voice commands to place orders.
4. Everyone will be given a telephone number at birth that will never change no matter where they live.
5. All forms of recreation,_such as cinemas, bowling, concerts and others, will be provided free of charge by the city.
6. All cars will be powered by electricity, solar energy or wind, and it will be possible to change the color of cars at the flick of a switch.
7. Distance surgery will become common as doctors carry out operations from thousands of miles away, with each city having its own telesurgery outpatient clinic.
8. Old people and people with disabilities will be able togo anywhere in the world using high－tech cameras attached to their heads.
9. Traveling in space by ordinary citizens will be common. Each city will have its own spaceport.
