Guam is a beautiful, small island in the Pacific Ocean. You’ll find happy songbirds, clear blue water, and leafy forest there. But the small island has a big problem: snakes. There are about 2 million brown tree snakes living in Guam.
The snakes likely arrived in the 1940s. They probably slipped(滑行) unseen onto ships and planes heading to Guam. Once there, the snakes laid eggs. Snake families grew. The snakes have no natural enemies to eat them on Guam. Soon, the island was covered with these snakes.
The brown tree snake has had a devastating effect. The snakes eat birds. There used to be 12 kinds of birds on the island. But these snakes have killed off nine kinds of the birds. The snakes can grow to be 10 feet long. They often bite humans. They climb onto power lines and make the electricity go out. This causes millions of dollars in damage.
Scientists have tried many different ways to control the number of snakes. They have used snake traps and snake-sniffing dogs. Nothing seemed to work. Nothing, that is, until they found a surprising secret weapon: killer mice.
Scientists found out that there is one easy way to kill brown tree snakes. They could give them a medicine called Tylenol. People take Tylenol for headaches and other pains. Even a little bit of Tylenol can kill a brown tree snake.
But how would scientists get the tree snakes to eat Tylenol? They came up with a plan. First, the experts put the medicine into dead mice. Then they attached each mouse to a mini paper parachute(降落伞). Planes dropped the mice over Guam. The parachutes got caught in the trees. The mice became dinner for the snakes that live there.
Has it worked? So far, research shows that there are fewer snakes because of the mice. The worry is that it may be too late to clear the snakes, but Mr. Vice from Guam’s Department of Agriculture says this should not stop the islanders from trying. “Our long-term goal is to kill the snake off completely,” he says.
1.What can we learn about the brown tree snakes?
A. They were shipped to Guam on purpose.
B. They were not native to Guam.
C. They were at risk in the 1940s.
D. They grew very slowly.
2.What does the underlined word “devastating” in Paragraph 3 mean?
A. Magical.
B. Interesting.
C. Short-term.
D. Damaging.
3.What was a more workable way to kill the brown tree snakes?
A. Using snake traps.
B. Putting Tylenol in the trees.
C. Bringing in their enemies.
D. Letting them eat Tylenol carried by mice.
4.What does Mr. Vice think of solving this snake problem?

The Galapagos Islands are in the Pacific Ocean, off the western coast of South America They are a rocky, lonely spot, but they are also one of the most unusual places in the world. One reason is that they are the home of some of the last giant tortoises（乌龟）left on earth.
Weighing hundreds of pounds, these tortoises go slowly around the rocks and sand of the islands. Strangely, each of these islands has its own particular kinds of tortoises. There are seven different kinds of tortoises on the eight islands, and each kind is slightly different from the other.
Hundreds of years ago, thousands of tortoises were around these islands. However, all that changed when people started landing there. When people first arrived in 1535, crews would seize as many tortoises as they could. They would roll the tortoises onto their backs when they were brought onto the ships. The tortoises were completely helpless once on their backs, so they could only lie there until used for soups and stews. Almost 100,000 tortoises were carried off in this way.
The tortoises faced other problems, too. Soon after the first ships, settlers arrived, bringing pigs, goats, donkeys, dogs and cats. A11 0f these animals ruined life for the tortoises. Donkeys and goats ate all the plants that the tortoises usually fed on, while the pigs, dogs and cats ate thousands of baby tortoises each year. Within a few years, it was hard to find any tortoise eggs-or even any baby tortoises.
Finally, in the 1950s, scientists decided that something must be done. The first part of their plan was to remove as many cats, dogs and other animals as they could from the islands. Next, they tried to make sure that more baby tortoises would be born; This slow, hard work continues today, and, thanks to it, the number of tortoises is now increasing every year. Perhaps these wonderful animals will not disappear after all

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.
For thousands of years, Polynesian people lived the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.
Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸盐)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine. When a company strip-mines, it removes the top layer of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.
1.What might be the author’s purpose in writing the text?
A. To seek help for Nauru’s problems.
B. To give a warning to other countries
C. To show the importance of money
D. To tell a heartbreaking story of a war.
2.The ecological disaster in Nauru resulted from _______.
A. soil pollution B. phosphate overmining
C. farming activity D. whale hunting
3.Which of the following was a cause of Nauru’s financial problem?
A. Its leaders misused the money
B. It spent too much repairing the island
C. Its phosphate mining cost much money
D. It lost millions of dollars in the civil war.
4.What can we learn about Nauru from the last paragraph?
A. The ecological damage is difficult to repair.
B. The leaders will take the experts’ words seriously.
C. The island was abandoned by the Nauruans
D. The phosphate mines were destroyed

Located in the Indian Ocean, the Maldives (马尔代夫) are among the most beautiful islands in the world, with sandy white beaches, clear water, and amazing coral reefs (珊瑚礁). The country depends on tourism, fishing, and shipping. But the rising sea level and the carbon pollution causing warming oceans are threatening (威胁) their existence.
The Maldives have asked for international help. They are a tiny country. The World Bank, the United States, the European Union, and many other groups have offered money to develop safeguards against climate change.
To protect the islands, the Maldives have built sea walls and increased the elevation (海拔) of important buildings and services such as the two interactional airports, which lie just 165 feet from the coastline.
They're also building up islands such as the Hulhumale, The new island is surrounded by nine-foot sea walls. More than 40,000 people live there. The plan is to house 240, 000, providing new opportunities for jobs. The goal is an excellent planned community with sustainable housing and buildings sensitive to the environment and needs of the people.
The government will move people living on smaller, lower-lying islands to the new built-up islands. The new islands offer free houses, new schools, health hospitals, fresh water, and waste treatment. Depending on tourism, the country hopes to build 50 more tourist islands.
