Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, or simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever.
Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger. Why should people care Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks (鹰), the com and grain they stored would be destroyed by rats and mice. Why Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiply (繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws to protect animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animal on the danger list. Slowly, the number of some animals in danger is growing.

The Amazon Rainforest: A Natural Treasure
Welcome to the Amazon rainforest. As the largest rainforest in the world, it plays a significant role in maintaining the fine balance of the Earth's ecosystem.
The Amazon rainforest crosses into eight countries. With an area of 5.5 million square kilometers, the Amazon rainforest is more than half the size of China. The Amazon River, from which the rainforest gets its name, is about 6,400 kilometers in length. On its journey from the mountains to the ocean, the river supports many different ecosystems. __1___
The forest's different levels support an unbelievable variety of wildlife. At the bottom, there is a system of roots beneath the ground. Above that is the mass of leaf litter on the dark forest floor.
___2__ Then there are the towering ancient hardwoods, and finally the tops of the tallest trees many metres above the ground. Each level of the forest forms its own little world, and is home to different kinds of living things.
More than 1,300 species of birds and over 400 species of mammals hide among the jungle's plant life. The jaguar(美洲豹) is one example. It has yellowish-brown coat with black spots. While a significant number of jaguars survive here, they are only one element of this forest's food chain. ___3__ These frogs, in turn, feed on insects which eat leaves and fruit. When a jaguar dies, a tiny army of microorganisms helps break down its body and return the nutrients to the earth.
The Amazon rainforest breathes life into the planet by absorbing carbon dioxide and producing over 20 percent of all the Earth's oxygen. __4___ Moreover, the Amazon rainforest is a treasure house of species that can be used for food or medicine. Yet there is one major danger to these irreplaceable plants and animals: us.
___5__ As the impact of human activities such as agriculture and cattle fanning continues to grow and the list of species in danger of extinction becomes longer, we are left with a question: can we afford to damage the "lungs of the planet"
A.They feed on many species, including frogs.
B.Thus, it's often known as the "lungs of the planet".
C.Rivers tend to be the easiest way to enter the forest.
D.The next level is made up of shorter plants with large leaves.
E.They give this area the richest species of plants and animals on the Earth.
F.Currently the trees in the Amazon rainforest absorb around 500 billion tonnes of carbon dioxide each year.
G.Over the past 50 years, 17 percent of the rainforest has disappeared due to human activities.

It was late, about 10: 15 p. m., when Janice Esposito arrived at the Bellport train station; she jumped into her Honda Odyssey and began the 20-minute drive home to her husband and seven-year-old son. She'd just returned from visiting her mother and had traveled the route many times before. She practically 1 on autopilot: a left onto Station Road, then a left on Montauk Highway, and then— wham! Out of nowhere a car T-boned Esposito's minivan, 2 her to move backward some 100 feet onto the railroad tracks. She 3 in the minivan, bruised (撞伤) but mostly just knocked out by the 4 and the airbags.
As it happened, Pete DiPinto was getting ready for 5 . He'd just closed his book and was getting under the covers when he heard the sound of metal on metal and breaking glass coming from not far outside his bedroom window. A volunteer 6 and retired teacher, DiPinto, 64, never 7 to think. He grabbed a flashlight and, still dressed in his pajamas (睡衣), ran out the door. "Any firefighter would have done what I did," he told Nevosday. "We're always on duty."
The first car he came upon, 2,000 feet from his front yard, was the one that had 8 Esposito. Once DiPinto concluded the driver was OK, he looked around and 9 Esposito's minivan positioned on the railroad tracks. And then he heard a terrible sound: the bells signaling an oncoming train.
"The gates were starting to come down," he told Nezvsday. "I see the headlight of the train." DiPinto ran quickly to Esposito's minivan and knocked on the driver's side window. She 10 looked at him, her eyes unfocused. "I don't know where I am," she said. She seemed unhurt. "Honey, you're on the railroad 11 ," DiPinto shouted. "We have to get you off right now!" He pulled hard on the handle, but the door was crashed in and 12 . The heavy diesel train, traveling at 65 miles per hour, was moving fast toward them. DiPinto ran to the passenger side and threw open the door. "Please, don't let her be 13 ," he thought. He pushed aside the deflating (瘪了的) airbags, grabbed Esposito's arms, and pulled her toward him across the passenger seat until he could help her out and quickly get her to 14 behind a signal box a few feet away. Within six seconds, he estimated, the train crashed into the minivan. "It was like a Hollywood movie" DiPinto told reporters the next day.
But this one had a twist. "Last night," South Country Ambulance chief Greg Miglino told CBS New York, "the 15 arrived in pajamas, not in a fire truck."

一、阅读理解
Parts of Africa are covered by a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts (蝗虫) that are traveling across the continent eating everything in their path.
And now in the battle to stop this disaster, a radio station in Senegal, West Africa, is offering listeners 50 kilograms of rice if they can catch and kill 50 kilograms of locusts. "We think this idea will get more people to take part in the war on the locusts," said Abdoulaye Ba, from Sud-FM, a radio station in one of Senegal's worst affected areas.
This is West Africa's biggest locust disaster in 15 years, and it is moving east, causing huge damage to crops. As they move, they produce young and increase their number and will soon threaten(威胁) Sudan in the northeast of Africa. Some say it could reach Asia. Experts say the harmful effect on crops in areas already suffering from food shortage and war could cause many people to go hungry. Governments in the areas are not well equipped to fight the pest.
Although leaders of 12 countries have agreed on a plan, it is not expected to be enough. "We are now treating 6,000 hectares(公顷) per day with pesticide (杀虫剂), but we need to treat 20,000 hectares per day in order to have any hope of controlling this disaster," said Mohamed Abdallahi Ould Babah, director of locust control in Mauritania.

A.West Africa's united effort in fighting a disaster

3.The locust disaster ______.
A.will be even more serious in Asia
B.is out of control
C.is affecting only the warning areas
D.cannot be stopped unless twice as much pesticide is provided for the affected areas
4.Which of the following is NOT mentioned
A.A radio station offers a reward for fighting locusts so that more people will join in the effort.
B.Senegal is to the west of Sudan.
C.The locusts can cause such damage mainly because it has no natural enemy in West Africa.

Dear John,
An animal protection organization in our city is going to hold an activity to set free wild animals to nature in the forest park at 10 o'clock next Saturday Morning. I would like to invite you to take part in it.
The organization has been working to protect wildlife. The workers have rescued many wild animals, including some rare ones. This time they are going to free some of the animals, because they should live in the natural environment. I think it must be exciting to watch these animals to return to the wild!
Looking forward to your early reply!
Yours,
Li Hua
