There are places in North America where great cities once stood. There were gardens, trees and grass. But now these places are like deserts. Scientists began to study this land to find out what had happened. Many of them believe the land died when the trees were cut down.
Trees help other plants grow. Tree roots (树根) hold the soil in place. They keep the wind from blowing away the soil. Leaves on the ground keep rainwater from running off. Trees near farms can help to stop strong winds.
Once there were hundreds of farms in the northwest of the US. Then the farms turned into fields of dry land. This was because few trees grow there.
Now we try to save trees. In many places, when a tree is cut down, a new tree is planted in its place. We don’t want the land to die.

Do you know why different animals or pests (害虫) have their special colors Colors in them seem to be used mainly to protect themselves.
Some birds like eating locusts (蝗虫). But birds cannot easily catch them. Why It is because locusts change their colors together with the change of the colors of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is protecting themselves. Bears, tigers and other animals move quietly through forests. They cannot be seen by hunters. This is because they have the colors much like the trees.
Have you ever noticed an even stranger act An octopus (章鱼) can send out a kind of very black liquid when it faces danger. While the liquid spreads over, the enemies cannot find it. And it immediately swims away. So it has lived up to now though it isn’t strong at all.

Rivers are one of our most important natural resources（自然资源）. Many of the world’s great cities are located on rivers, and almost every country has at least one river flowing through it that plays an important part in the lives of its people.
Since the beginning of history, people have used rivers for transportation. The longest one in the United States is the Mississippi. The lifeline（生命线）of Egypt is the Nile. To the people of India, the Ganges is great, but it is also important for transportation. Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation（航海）, however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops, and chances for fun and recreation for the people who live along their banks. In order to increase the supply of water for crops, engineers sometimes build a dam（大坝）across a river and let a lake form behind the dam. Then people can use the water not only to irrigate（灌溉）their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits（利益）of this natural resource.
11．The greatest river for navigation is ________.
A．the Amazon B．the Nile C．the Mekong D．the Mississippi
12．Which is WRONG

A．keeping the rivers clean B．only making electricity
C．washing clothes D．irrigation and making electricity
14．The water in the river is polluted because of ________.
A．people’s drinking water too much B．people’s swimming in the river too much
C．chemicals and other materials D．people’s building a dam across a river
15．The best title of the passage is ________.
A．Rivers in Cities B．The Importance of Rivers
C．Transportation D．Natural Resources
As a mountain, 1,642-foot squad Peak isn’t that impressive (给人深刻印象的). But its views attract many hikers (远足者). Hear Grant, a college student at Ithaca College, was one of them.
While waiting for his mother one day in August 2019, Grant watched other hikers enjoy the view. One hiker, dressed in pink, was looking over the lip of the cliff (悬崖) with her husband.
When Grant’s mother rejoined (与……再会合) him, the two continued on their way. Suddenly, he heard something scaring. “Paula! Paula!” a man shouted crazily. Grant turned around quickly.

She kept trying to move, and every time she moved, she slipped a little more. Afraid that in her unclear state of mind she might fall off the rock to her death, Grant climbed on all fours up a tight and narrow path by digging into the earth with his fingers and feet until he reached Paula.
Paula was moaning (呻吟), almost senseless. Grant gently put her hand in his, trying to keep her mind off the pain by keeping asking her questions: “Where are you from Do you have kids ” Soon, they were joined on their perch (歇脚处) by another hiker named Simon.

On my recent trip to Sydney with my parents, we visited the Wildlife Park.
The Wildlife Park has lots of different animals and birds. Some are native (当地的) toAustralia and can only be found there. There are over 600 animals there, including kangaroos,koalas and crocodiles (鳄鱼). They are kept in their natural environment. I like the Wildlife Park better than a zoo where most of the animals are in cages (笼子).
We first spent some time with the kangaroos. We were allowed to touch and feed them. It was very exciting to be so close to them. There were koalas there too. They looked very cuddly (令人想拥抱的). Although we were not allowed to carry them, I got to take a photo with one. It is a wonderful souvenir (纪念品) of my holiday in Sydney.
The Wildlife Park has plenty of freshwater and saltwater crocodiles. Some of them arereally big and scary (吓人的) with huge teeth! I did not want to get too close to them.
There was also a bird show. The keepers showed us different species (种类) they had. I saw an old parrot which could “talk”. It made a great impression on me.
I enjoyed the trip very much. There was so much to see.

What do the following animals have in common (相同) Pandas, tigers, whales, lions and camels They are all in danger!
Animals are in danger for many reasons. Sadly, humans are behind them! Here are three reasons.
Excessive hunting (过度猎杀): For centuries, humans have hunted elephants for their tusks, killed tigers for their fur, and caught many other animals for meat.
Foreign animals: In 1505, Europeans discovered a beautiful island in the Indian Ocean named Mauritius. They brought dogs, pigs, monkeys, and rats with them. It was bad news for dodo birds. They did not have any natural enemies before. They picked up fruits falling down from trees and built their houses on the ground. Shortly after humans came, however, dodo birds were in big trouble — man killed them for their meat, and those animals broke their homes and ate their eggs. The dodo birds first became rare and then extinct. The last dodo bird was killed in 1681.
Loss of homes: We cut down forest for farming. We cut down trees to build houses. We build dams to make sure that we have enough water to use. When we are trying to make our lives comfortable, the land for animals to live on becomes less and less.

Techeng Island(特呈岛)lies in the southeast of Zhanjiang. The villagers there used to make a living by fishing. But now, most of them make much money by doing business. They believe that their island is a gift from nature and they give thanks to it every day. In 2003, President Hu Jintao came to visit the island and pointed out that the government of Zhanjiang should take the island into a “civilized new eco-tourism island”(文明生态旅游新海岛).

All aboard! Let’s take a ride on the world’s highest railway—the Qinghai-Tibet Railway（青藏铁路）. Sit back and enjoy the journey. Get ready for the trip of a lifetime.
We’re leaving Qinghai Station. The scenery along the way is some of the wildest in all of China. Keep your eyes open as we race through this beautiful land. You might see a rare Tibetan antelope（藏羚羊）from your window.

Before we begin our journey, let’s learn about this amazing railway. It’s truly one of the great engineering wonders of the 21st century. When it was completed on July 1, 2006, the Tibet Railway set nine world records, including the world’s highest railway at 5,072 metres above sea level, the world’s highest tunnel（隧道）at 4,905 metres, and the longest tunnel ever built on permafrost（冻土）.
As we travel higher, the air gets thinner and thinner. Soon there will only be 50 to 60 percent of the oxygen which we are used to breathing. But don’t be afraid. Each rail car has two separate oxygen systems. One system spreads oxygen throughout the train at all times. And each passenger can also get a personal oxygen mask just like those used in planes.
Here are a few more things to think about as our train leaves the station. The designers solved three main challenges when building this great railway. First, the high altitude（海拔）made the task difficult because there was no enough oxygen. Second, much of the railway runs across permafrost, a type of ground that keeps changing as the weather warms and cools. Finally, the railway goes through some of the most sensitive ecology（敏感的生态环境）in China. Great care was necessary to make sure of the smallest possible influence on nature.
All three challenges were met, making our trip possible. All aboard! The train to Tibet is leaving in fifteen minutes.
45．Where are the passengers
A．On a bus. B．On a train. C．On a ship. D．On a plane.
46．How does the text show the railway is amazing in paragraph 3
A．By telling a story. B．By using a designer’s words.
C．By introducing its world records. D．By comparing the present with the past.
47．How many oxygen systems are there in each rail car
A．One. B．Two. C．Three. D．Four.
48．Which of the following increased the difficulty of building the railway
A．The changing ground. B．The polluted air. C．The dangerous animals. D．The hot weather.
A river is a flowing（流动的）, moving stream of water. Usually a river feeds water into an ocean, lake, pond, or even another river. Rivers can differ in size and there is no strict rule on how big a flow of water must be to be called as a river. Here are the five longest rivers in the world.
The Nile RiverThe Nile River is 4,135 miles long. It is located in the continent of Africa, mostly in the countries of Egypt and Sudan. It flows north into the Mediterranean Sea.
The Amazon RiverThe Amazon River is 3,980 miles long. It is located in the continent of South America and flows through several countries including Brazil, Venezuela, Bolivia, and Ecuador. It ends at the Atlantic Ocean.
The Yangtze RiverLocated in China, the Yangtze River is 3,917 miles long and flows into the East China Sea.
The Mississippi River and the Missouri RiverThe river system of the Mississippi River and the Missouri River is the longest river system in North America at 3,902 miles. It flows south into the Gulf of Mexico.
The Yenisei RiverThe Yenisei River starts in Mongolia and flows through Russia to the Kara Sea in the Arctic Ocean. It’s 3,445 miles long.
There are 76 rivers in the world over 1,000 miles long. A lot of people think that rivers always flow south, but 4 of the 10 longest rivers in the world flow north. The United States alone has around 3.5 million miles of rivers. Four of the top 10 longest rivers flow through China at some point.
49．The Nile River is _________ longer than the Yangtze River.
