Most animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系) which is good for both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.
Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals(珊瑚) of the sea. In their skins they have tiny plants which act as “dustmen”, taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.
1.We learn from the text that corals depend on plants for______.
A. food B. light
C. oxygen D. comfort
2.Some birds like to sit on a sheep because _______.
A. they enjoy travelling with the sheep
B. they can eat the parasites on the sheep
C. they depend on the sheep for existence
D. they find the position most comfortable
3.The underlined word “they” in the first paragraph refers to ____.
A. birds and sheep B. birds and parasites
C. parasites and sheep D. sheep, birds and parasites
4.What does the second paragraph mainly discuss?
A. Some animals live better together.
B. Some plants depend on each other for food.
C. Some animals and plants develop their relationship easily.
D. Some animals and plants depend on each other for existence

Humans share Earth with many different kinds of wildlife. However, many of our animal friends may not be around for much longer.
According to the Living Planet Report released by the World Wildlife Fund (WWF) in October, the populations of animals including mammals, birds and fish have fallen by an average of 60 percent since 1970.
“We are sleepwalking towards the edge of a cliff (悬崖), Mike Barrett, executive director of science and conservation at WWF, told the Guardian. “If there was a 60 percent decline (下降) in the human population, that would be equivalent (等于) to emptying North America, South America, Africa, Europe, China and Oceania."
According to the report, one of the biggest causes of wildlife losses is human activity. Three- quarters of the world's land is largely affected by human activity. Many natural habitats (栖息地) have been destroyed to create farmland.
About 300 mammal species are dying out because we eat them. Another example is the industrial over fishing of the oceans, the Guardian noted.
“The astonishing decline in wildlife population…is a reminder and perhaps the ultimate (最终的) sign of the pressure we exert (施加) on the plane,” Marco Lambertini, the director general of the WWF, wrote in the report.
These developments lead scientists to believe that there could be a sixth mass extinction, the first to be caused by humans according to the Guardian. There have been five mass extinction before, the last being 655 million years ago. That time it was the dinosaurs that died out.
WWF has called on world governments and businesses to strike a deal to protect people and nature.
Neither is the situation in China promising. According to a report by China Daily in November, Chinese paddlefish (白鲟) in the Yangtze River, may have become extinct. And there are now less than 500 green peafowl (孔雀) in the wild, reported CCTV in June.
To protect endangered animals, measures have been taken in China and progress has been made. For example, China has banned the use of rhino horn and tiger bones; and ivory (象牙) trade, reported China Daily. It also emphasizes increasing public, awareness by holding activities when celebrating the World Wildlife Day.
But more efforts are still needed to protect wildlife in China and around the world. “We are the first generation to know we are destroying our planet and the last one that can do anything about it,” WWF UK Chief Executive Tanya Steele told CNN.
1.What did the Living Planet Report point out?

2.What is a main cause of the loss of the fish population, according to the Guardian?

C.Climate change. D.Environmental pollution.

A.China provides a model of animal protection for other countries.
B.China has made some progress in protecting endangered animals.

Have you wondered why different animals or pests have their particular colours? Colours in them seem to be used mainly to protect themselves.
Birds, especially seagulls are very fond of locusts (蝗虫), but birds can’t easily catch locusts because locusts change their colours together with the change of the colour of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown colour as crops have. Some other pests with different colours from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of colouring is to protect them. Bears, wolves and other beasts move quietly through forests. They are usually invisible(can’t be seen) to the eyes of hunters, because they have the colour much like the bark（树皮）of trees.
An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all.

A.the change of colour in locusts
B.animals or pests can dye（染色）themselves different colours

A.their enemies can easily find them and eat them
B.they have the habit of coming out in darkness
C.it’s easy for them to destroy plants in darkness
D.birds take their rests when night comes
4.A certain fish living in seas has lived through millions of year because _______.
A.it is the most powerful in the sea
B.no other fishes can swim as fast as it can
