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 greatest engineering wonders of the 21st century. When it was opened to traffic 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(永久冻土层).
As we travel higher,the air gets thinner and thinner. Soon there will only be 50 to 60 percent of the oxygen which is used to breath. 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.
21. Where are the passengers
A. On a bus. B. On a train. C. On a ship. D. On a plane.
22. 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.
23. How many oxygen systems are there in each rail car
A. One. B. Two. C. Three. D. Four.
24. 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.
B
A river is a flowing(流动的),moving stream of water. Usually a river feeds water into the 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 River The Nile River is 4,135 miles long. It is located in the continent(大陆)of Africa,mostly in the countries of Egypt and Sudan. It flows north into the Mediterranean Sea.

How to Make Our Hometown More Beautiful
The clean water and green mountains are our treasures. But the environmental pollution is a bit serious these days. In order to make our hometown more beautiful,we students should do something to protect the environment.
First,we should turn off the lights to save electricity when we leave the room. Second, let's walk or ride a bike to school. It is not only good for the environment but also good for our health. Third,we should also advise our parents to take the bus to work instead of driving and use reusable bags when shopping. We should stop using plastic bags to reduce pollution. Fourth,we should try to sort the rubbish and throw it into the dustbin every day.
How important it is for us to protect the environment!Only if we know what to do in our daily life can we make a difference.
