Animal Conservation

Many animal and plant species have become extinct（灭绝的）and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve（保护）the natural world they inhabit（居住）is now more important than ever.

Dodo

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 last one was killed in 1681.

Rhinos

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（偷猎者）.

The Giant Panda

The future of the World Wildlife Fund's symbol is far from certain. As few as 1000 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 animals continued existence.

Whales

The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world's oceans have been declared 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（碰撞）with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.

Tigers

The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 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.

It implies that _______.

A．The Dodo lacked the ability to protect itself from other animals

B．Sailors to the Island of Mauritius lived mainly on the Dodo

C．The Dodo used to be a strong animal that liked fighting.

D． The Dodo, pigs, monkeys and rats were the natives to the Island of Mauritius

Which group of the following animals has already ceased to exist according to the text?

B．The Rhino, Whale and South China Tiger.

C．The Rhino, Panda, Whale and Tiger.

D． The Dodo and the Bali, Javan, and Caspian tigers.

______ can serve as a cure for certain diseases.

A．The number of South China tigers has reached crisis point.

B．Many animals are threatened with extinction as a result of human activity.

C．People hunt for the endangered animals for high profit.

D． The Whale is the representing mark for the World Wildlife Fund．

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊猫）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多样化饮食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

We can infer from the text that humans and animals _________.

A. depend on one sense in choosing food B. are not satisfied with their food

Which of the following eats only one type of food?

A. The white butterfly. B. The small bird.

C. The bear. D. The fox.

Certain animals change their choice of food when ___________.

A. the season changes B. the food color changes

C. they move to different places D. they are attracted by different smells

We can learn from the last paragraph that __________.

A. food is chosen for a good reason B. French and British food is good

C. some people have few choices of food D. some people care little about healthy diet

We could all see the Murray Uiver slowly moving back, but now all the water was gone . I couldn’t believe that the Murray had dried up, not one drop of water left.

One morning I went down to the river to try and catch some fish when I saw my boat high and dry (搁浅) on the bank . I rushed down the river and saw all mud—no water . The fish were just lying there, dying . I looked up to see if my friend was there . There was the nest but no eagle（鹰）. I called out to her with my special whistle which I made out of steel.

Suddenly a big shadow came over to me and the eagle landed in her nest and gave her young the food she was out getting while I whistled. But then I suddenly noticed she was getting thinner and had a bit of sheep’s wool in the side of her talon（利爪）. It was deadly quiet by the river bank , except for some sound from my dog. And also I couldn’t see one native animal or bird.

When I walked inside the kitchen. Mum and Dad had sad looks on their faces. “It’s time for us to move ,Son, because the river can no longer provide for（养活）us,” said Dad . I ran out of the kitchen door with tears in my eyes , and down to the river bank, to my favorite spot. I said goodbye to my eagle , crying.

When it was time to go , I saw my eagle fly up into the air with her chicks in her talons , going away to try and find another home ,just like us.

Everyone knows the smart black-and-white dog that sits on top of a red doghouse with his best friend---a bird called Woodstock.

Created by the American cartoonist Charles Schulz in 1950, the clever dog is loved by generations of kids and adults. He speaks more than 20 languages and appears daily in 26,000 newspapers around the world.

When Snoopy first appeared, he was not different form other pet dogs. But two years later, he had begun to speak with simple words and sounds. By 1957 he could walk on two legs and was going to school with his master, Charlie Brown, who failed in just about everything. Later he learned to use the typewriter.

Snoopy has done lots of jobs. He has been a bow-tie wearing lawyer, a tennis player, an Olympic figure skater, a world famous grocery checkout clerk, a pilot and even the first astronaut on the moon.

However, Snoopy has always dreamed of being a famous writer. The beginning of his story is always, “It was a dark and stormy night…” Unfortunately for him no one has ever wanted to publish the story.

In love, Snoopy is as much of a failure as Charlie Brown is at baseball. He easily falls in love but always has his heart broken. He eats to forget, but it never works.

Snoopy is an insightful, feel-good and sometimes sad dog. If you think a little about words, you might find them full of life lessons. Among his most famous lines are “To live is to dance, to dance is to live.” And “Yesterday I was a dog. Today I’m a dog. Tomorrow I’ll probably still be a dog. Sigh! There’s so little hope for advancement”.

1. Snoopy has done all the following jobs except ____________.

A. a lawyer B. a player C. a clerk D. a writer

2. From the passage, we can learn that _________.

A. Snoopy is always a sad dog B. Snoopy can not speak in the beginning

3. It can be inferred that Snoopy ____________.

A. has many bird friends and relatives B. is a well-known writer and clerk

C. has been unfortunate since it was born D. is very popular in the whole world

4.The word “advancement” in the last paragraph probably means__________.

A. success B. progress C. growth D. popularity
