Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.
The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(两栖动物).
Who is to blame?
Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim（受害者）of habitat destruction.
Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”
In China the new reserve（保护区）itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.
"The country's natural resources(资源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.
The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average（平均水平） of 11% and the rate in most developed countries.
Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment（投资） in such reserves at all levels.

A. A union for listing animals and plants on the earth
B. A group of volunteers who are interested in wildlife
C. An organization concerning the protection of rare species' survival
D. A government made up officials, scientists and experts
2. What can be concluded from the passage?

B. The IUCN does most of the protection.
C. The efforts China makes has paid off.
D. Enough is done in wildlife protection.
3.Which of the following is not the cause of the disappearance of the animals?

Birds’ feathers are some of the most strikingly variable animal characteristics that can be observed by the eyes. The patterns that we see in birds’ feathers are made up of combinations of scales, bars, and spots.
We already know why birds have colored feathers. Generally, the color of feathers may protect a bird from being noticed by the enemy in the environment, or it can make a bird more appealing to potential mates by helping them to stand out. These aspects are well known. A greater mystery has been how the patterns are created.
Dr. Ismael Galván and his team studied the color of feathers to see what types of colors were present in birds’ complex feather patterns. The study shows they mainly consist of two types of colors: melanin（黑色素）, which produce a range of black, grey, brown, and orange color, and carotenoids（类胡萝卜色素）, which are used to create brighter colors.
Birds cannot produce carotenoids on their own. For feathers with bright colors, birds must consume food items that contain these paints, and the carotenoids circulate through the blood and to the feather. Melanin, on the other hand, is produced by special cells in the birds’ bodies.
The team found that about 32% if the species studied have complex color patterns, with the vast majority of these complex patterns produced by melanin rather than carotenoids. If the birds were artists, they would use carotenoids as a broad brush to produce color patches, with melanin as a detail paint brush to produce more complex designs.
But a few birds are exceptions to this rule: Three bird families do have complex patterns without melanin.
1.What does the underlined word “it” in paragraph 2 refer to?
A. The environment. B. The color.
C. The feather. D. The enemy.
2.What will happen if birds can’t get enough carotenoids?
A. They’ll gradually die out. B. Their color will be less bright.
C. They will get caught eventually. D. They’ll be discovered more easily.
3.What rule can we get from paragraph 5?
A. All birds have complex color patterns.
B. Birds are expert in painting colors.
C. Melanin plays a greater part in bird colors.
D. Carotenoids can bring 32% of the color patterns.
4.Which can be the best title for the text?
A. How Do Birds Get Their Colors B. Which Color Is Common to Birds
C. How Do Birds Tell Different Colors D. Why Birds Have Colored Feathers

Tigers are among the most admired and most feared animals in the world . When we think of a tiger, we think of danger. We think of the big teeth and large feet of it. We also think of beauty.
The tiger is a hunter that hunts alone. In fact , tigers are probably better than any other land mammal(哺乳动物) at catching large animals without help. Even so, the life of this big-game hunter isn’t easy. Finding food can be difficult, especially for a tiger that is old or weak. Most of the animals it tries to attack get away. A tiger sometimes goes weeks without eating. When that happens, it may hunt animals that can be dangerous even for a tiger.
When they are in a bad situation, some tigers may even attack humans. But in fact, tigers kill very few people each year. Most tigers run away when they see people.
What tigers have done to people can’t compare to what people have done to tigers. Over the last 200 years, we have almost killed tigers in the wild(野外). Today, the tiger is one of the most endangered animals on Earth.
A tiger may live 20 years or more, if it is not disturbed by humans. Female(雌性的) tigers usually live longer than male(雄性的)tigers, because the males live more dangerously.
It isn’t easy for people to tell a male from a female unless the female happens to be with her babies.Only females take care of the young. The big difference between males and females is size. Male tigers are much bigger.
Tigers are big eaters. In a single year, one tiger must eat about 70 deer or other large animals. That is one reason why tigers hunt alone. If they lived in big groups, they could never find enough animals to feed them all.
1.What’s the topic sentence of Paragraph 2?
A. The tiger is a hunter that hunts alone.
B. A tiger sometimes goes weeks without eating.
C. The life of this big-game hunter isn’t easy.
D. Most of the animals it tries to attack get away.
2.The easiest way to tell a male tiger from a female one is by looking at their______
A. size B. running speed
C.way of hunting D.claws
3.What can we learn from the passage?
A. A tiger can only live about 20 years.
B.It is people who make tigers endangered
C.Many people are killed by tigers every year.
D.Male and female tigers take care of their babies together.
4.According to the passage, why do tigers hunt alone?
A.They can run faster hunting alone.
B.They can’t get along well with other tigers.
C.They can hide themselves easily in this way.

Wolves are important animals in the traditions and stories of most Native American tribes. To Native Americans, wolves often represent bravery. The animals also are signs of strength, loyalty, and success at hunting. Other cultures--such as the ancient Celtic and Nordic peoples-also placed high value on wolves.
However, from the wolves in horror films to the wolves in children’s stories, wolves get a bum rap(不公正的惩罚) in both literature and English expressions.
To begin with, there is the term lone wolf. The lone wolf isn’t a bad person. But they like to do things on their own. However, the term can mean something less than desirable. Lone wolf makes you think the person doesn’t want to be around people because he or she dislikes them.
Now, let’s move on to the home.
Parents might criticize their children for wolfing down their food. In other words, the child eats very quickly and without care. And if someone says a child was raised by wolves, that child has bad manners and is behaving like a wild animal. A wolf at the door means someone to whom you owe money is waiting just outside your door.
By the way, there are two popular wolf-related expressions that come from Aesop, the ancient Greek storyteller.
The first is a wolf in sheep’s clothing. A wolf in sheep’s clothing describes someone who acts and looks nice on the outside but is bad on the inside.
Aesop’s other wolf fable also involves a shepherd, but not a hardworking one. He is known as the boy who cried wolf. People who cry wolf are not trusted. People are so familiar with this story, you simply have to say cry wolf for them to know what you mean.
1.According to the passage, which group of people may think wolves are bad animals?
A. The ancient Nordic people B. The ancient Celtic people
C. Native Americans D. The English people
2.Which of the following can describe a person who often acts alone?
A. A wild wolf B. A lone wolf
C. A wolf at the door D. A wolf in sheep’s clothing
3.What may you probably mean by saying someone cries wolf?
A. The person is selfish B. The person is a liar
C. The person is stubborn D. The person is a troublemaker
4.What is the passage mainly about?
A. Stories about wolves
B. The research on wolves
C. Expressions about wolves
D. The cultural differences about wolves
