Have you ever been to Poyang Lake in winter? If so, you may have a chance to see thousands of Siberian(西伯利亚的) white cranes dancing on the lake. It's so fantastic. 1 That's why they appear in Poyang Lake.
The Siberian white cranes are known as the snow cranes. Experts say the Siberian white cranes are special when migrating(迁徙). 2 Chinese researchers first discovered the Siberian white cranes in Poyang Lake in 1980. Their migrating route(路线) has been well protected these years. 3
In 2017, a photography lover, together with many bird lovers, built the Siberian crane protected area. 4 It's known as "humans' closest place to Siberian cranes". Every year, these cranes fly to this area.
The cranes know whether the natural environment is good or not. They are like "ecological test paper(生态测试纸)" for the environment. 5 Now there are only about 4,000 Siberian cranes all over the world. We should protect them.

六、任务型阅读。
阅读下面短文，根据短文内容回答下列问题。
Mount Qomolangma is the highest mountain in the world, which is 8,848.86 metres high. It's called “the Roof of the World”. But Mount Kilimanjaro is the highest mountain in Africa. It is one of the most beautiful places on the earth which is 5,895 metres above sea level, so it is often called “the Roof of Africa”.
Climb lovers’ dream place—Mount Kilimanjaro
It is one of the world’s highest “walkable” mountains. People can climb the mountain all year round, but many people will choose to climb during the mountain’s two “dry” seasons, January to March and June to October. If they want to reach the top of it, they can climb in the rainy season too, but the weather condition may not be good and it may be difficult to achieve.
The beautiful snow cap of Mount Kilimanjaro
Even though it is hot there, the top of the mountain is covered with ice and snow the whole year. There are many famous stories of the snow cap of Mount Kilimanjaro. It formed about 11,000 years ago, but research showed that it might disappear.
One of the reasons for its possible disappearance is global warming. The high temperature is making the ice on Mount Kilimanjaro melt(融化). The beautiful snow cap of Mount Kilimanjaro is disappearing quickly.
1. How high is Mount Kilimanjaro?

2. When will many people choose to climb Mount Kilimanjaro?

3. How long has the snow cap of Mount Kilimanjaro formed?

4. What might cause the disappearance of the snow cap of Mount Kilimanjaro according to the text?

5. We can go to school by bike instead of taking cars. / We can plant more trees around the mountain. /...
2.
