Another small animal that tigers eat in Ranthambhore （a wildlife park in northern India） is the porcupine （豪猪）．These animals are spread widely across India in open areas and grasslands; they often live in the earth and between rocks．They are good diggers, and in Ranthambhore are nocturnal （夜出的）; they only come out at night．They weigh 12 to 16 kilograms and reach the length of 80 to 90 centimetres．They live usually on vegetables and fruit and seem to have a good sense of smell．Porcupines defend themselves when attacked by moving backwards with their quills upright, often making a strange noise．

Several times, I have found the remains of quills where a tiger has killed and eaten a porcupine, but I have never actually seen the kill．In spite of the quills, experienced tigers will try to kill clearly by biting the porcupine’s head, its weakest spot．But the quills are very sharp and can give painful injuries to young tigers．If the quills have gone in very deeply or if they are stuck in the tiger’s paw, it will try to pull them out．Often, it will be successful, and the wound will get better．But, if the quills have gone in very deeply or if they are stuck in the tiger’s neck or mouth, where they cannot be reached, the wound will often turn bad．If this happens, the tiger is in pain and is less able to hunt animals．It has to look for easier prey and so may turn to cows on the edges of the forest．From this, it is a small step to becoming a man-eater．

1. A porcupine is a small animal which _____．

2. The word “quill” here means ____．

3.According to this passage, what causes a tiger to become a man-eater?

4.What is the proper title for this passage?

In most people's opinion, the tiger is not an animal that we would ordinarily think of as being chicken. However, one tiger, which lives in an English zoo, turned out to be more cowardly（胆小的）than his keepers could ever have imagined.

Tanvir, a two-year-old Bengal tiger, got stuck at the top of a new 5m-high activity tower in the zoo, after climbing it for the first time.

The wooden tower had been designed to provide mental exercise for Tanvir by testing his ability of dealing with troublesome situations, but after climbing it in just a few seconds, he lost his courage when it came to coming back down. Tanvir went on to spend nearly two days at the top of the tower trying to collect the courage to attempt to get down.

A spokesperson for the zoo said that several days before Tanvir had taken half an hour to get down a lower tower only 1.5m high, and the taller tower had clearly been too much challenging for him.

"Every time he got to the edge, he looked out, put a paw over, and thought, ‘no, I cannot make it!" ’laughed Samantha Cordrey, Tanvir's keeper. In the end Tanvir's hunger defeated his fear, and after almost 48 hours he made his way down. Burying himself in a big meal just like a hungry pig, Tanvir seemed to forget such a shameful experience for a while.

It appears that his experience would not be the worst in Tanvir's life if he continued to act like a chicken. It is not known whether he will take courage to go back up his exercise tower again.

The whole episode（插曲）only serves to show the difficulties faced by zoo staff in creating environments that will improve animals' living ability in enclosed space.

1.When speaking of Tanvir's shameful experience, Samantha Cordrey might feel it was　　　　 .

A. funny　　 B. surprising　　 C. exciting　　 D. unbelievable

2.What made Tanvir get down the 5m-high activity tower at last?

A. The coldness of the weather.　　 B. The direction from his keepers.

C. The sufferings of being hungry.　　 D. The fear of being alone.

3.Why does the author say "this experience would not be the worst in Tanvir's life if..."(Paragraph 6)?

A. Because Tanvir's keepers will design more difficult exercise for him.

B. Because Tanvir is so cowardly that he has little courage to meet greater challenges.

C. Because Tanvir's bad health will bring him much trouble in practice.

D. Because Tanvir is always careless and often causes trouble by accident.

4.The zoo designed the 5m-high activity tower to　　　　 .

A. make Tanvir become brave　　 B. improve Tanvir's performance skills

C. let tourists watch Tanvir better　　 D. improve Tanvir's living ability

It’s known to us all that elephants are the biggest animals on land.

There are two kinds of elephants: African elephants and Indian elephants. The African elephant has a round head and very big ears. It has long teeth. Each of them can be as long as 3.4 meters and as heavy as 103 kilograms. African elephants live in forests in Africa. They eat leaves, roots and fruits.  Indian elephants are smaller than African elephants. They are found in forests in India, Malaysia and some other countries in South Asia. They live on grass. They can be trained to do a lot of heavy work and amuse(逗乐)people.

An African elephant lives as long as a man does. But an Indian elephant does not live that long.

It is a question that has long puzzled scientists—exactly why are tigers orange? One might think it makes them more obvious-particularly against a leafy green forest background. William Blake summed it up in his famous poem known by generations of schoolchildren: “Tyger, tyger, burning bright / In the forest of the night.” But now the answer is at hand.

While obvious to us, computer simulations (模拟) of what the big cats look to the main animals they hunt for, deer, show a different picture. Humans with normal colour vision, can see red, blue and green colours. But deer can only pick up blue and green light, they are effectively colourblind to the colour red, like some humans. It means the tigers’ orange colouration looks green to them, allowing them to mix perfectly into the background, new research claims.

Dr John Fennell at the University of Bristol and colleagues said that they used computers to estimate how noticeable a given animal was. They did this by using images of the environment in which the animal lives, and then creating images to see whether the camouflage helps the animal to mix in.

Dr Fennell writes that by simulating what the world looks like to animals who are “two-colour vision”—someone who cannot discover the difference between red and green—“we also identify the most suitable colours for hiding and visibility”.

Dr Fennell writes in the Royal Society Journal Inter face: “Considering the coat of a tiger, it has fur that appears orange to a three-colour vision observer rather than some shade of green, though the latter should be more appropriate color for an attack hunter in forests. However, when viewed as a two-colour vision observer, the tiger’s colour is very effective.”

The question then arises as to why tigers don’t grow green coats. Dr Fennell and colleagues write that mammals (哺乳动物) are not able to produce green fur. To do so would “require a significant change to mammalian biochemistry”. There is only one mammal known to have green fur but this is achieved through what might be considered as, well, cheating, not exactly real.

1.Why does the author mention the poem in paragraph 1?

A.To arouse reader s interest in poems.

B.To show the authors respect to the poet.

C.To answer the question of the color of the tiger

D.To stress the noticeable color of the tiger to us.

2.What color is inexistent in the eyes of deer?

A.Black. B.Red.

C.Blue. D.Green.

3.What does the underlined word “camouflage” mean in paragraph 3?

A.The cover of something.

B.The images of something.

C.The way of hiding something.

D.The way of hunting for something.

4.What can be inferred from the last paragraph?

A.The colour of tigers sometimes cheats people.

B.Getting green may prevent tigers from being extinct.

C.There are no mammals with real green fur in the world.

D.The tigers’ fur will probably evolve into green in the future.
