School isn’t just a time to learn Maths,Science and other subjects. It is also a time to learn the skills you’ll need to succeed in the real world.

One very important skill that can help a young person in their future is leadership. While some schools may allow more students to take turns to be class leaders,most schools allow only a few students to take on such roles.

The downside may be the sense of superiority（优越感）the class leaders have. These leaders may begin to feel that they have a right to give orders to their classmates to do the work rather than working as a team. In some cases,students may begin to think that they are above their fellow classmates in power and privilege（特权）.These certainly aren't the expected qualities of a future leader.

One school in Hangzhou has recently been praised for introducing a new model of student leadership. It allows each student to work as a class leader. The teachers there created a lot of opportunities such as electing class librarians and group reading leaders. Parents of students at the school praised the new arrangement. When the news hit the Internet,people also agreed and encouraged more schools to follow it.

Of course, with this model,the focus can still be on “policing” and telling on classmates, rather than encouraging peers and promoting cooperation. The most effective student leadership programmers should teach such things as personal and group responsibility, teamwork, problem-solving creativity, goal-setting, and communication. As students, you should see leadership opportunities as a chance to learn important skills for your future.

Imagine the year 1800. The sky roars（咆哮）with a great sound, like the sound of a thousand trains. The daytime sky becomes dark as sunlight is blotted out （挡住）. Is it a terrible thunder storm? No, in fact, it’s a group of thousands of passenger pigeons（信鸽）moving overhead! Hundreds of years ago, there were three to five billion passenger pigeons in America. Sadly, passenger pigeons have died out. None are left today.

Passenger pigeons were a migratory（迁徙的）bird. Migratory birds move about from season to season searching for places to nest（筑巢）and feed.The passenger pigeon migration covered from Canada all the way to Texas and Florida. During a migration, thousands of birds would fly together from morning to night or several days. People reported seeing flocks（鸟群） as large as a mile wide!

The migrations took place in spring and fall, when warmer weather brought forests to life with fresh food sources like nuts, seeds,insects and so on.

At first, it seemed as though passenger pigeons were an endless supply of tasty meat. When a large flock passed by, hunters could easily catch a few passenger pigeons without affecting the others. But later, hunters would travel to find nesting sites. A passenger pigeon nesting site might contain over one million birds. The birds usually nested close together, and hunters found them to be easy targets.

At last, this over hunting destroyed the pigeon population. The last known passenger pigeon in the world died at the Cincinnati Zoological Garden in 1914. The pigeon, named Martha, was twenty-nine years old. Although the extinction（灭绝）of the passenger pigeon is a terrible loss, it did have one happy result: it pushed people to create wildlife protection laws to protect other creatures.

A．The migration caused wanner weather and forest growth.	B．The Sun was blocked out by huge flocks of birds.

18. Why did hunters travel to nesting sites? ________

A．Hunters enjoyed taking long trips to follow the pigeons' migration.	B．It was too dangerous for the pigeons to be caught while flying.
C．It was impossible to hunt when passing flocks blotted out the Sun.	D．Hunters could catch larger numbers of birds at nesting sites.

19. How did the pigeon’s extinction lead people to create wildlife protection laws? ________

A．People learned that passenger pigeons had been protecting other species.	B．People wanted to make sure other species’ nesting sites held fewer animals.
C．People realized that passenger pigeons could not live very long in zoos.	D．People saw that unlimited hunting would cause more species to die out.

20. What this passage mainly tell us? ________

A．The migration of passenger pigeons.	B．How to protect passenger pigeons.
C．The extinction of passenger pigeons.	D．The passenger pigeons’ nesting sites.

A night concert celebrating the 110th anniversary（周年纪念）of Tsinghua University in Beijing attracted over 1,500 students and traditional Chinese music fans on Saturday.

Fang Jinlong, a master of the traditional Chinese instrument pipa, and three humanoid（人形）robots from the Tsinghua Moja Robot Band performed several Chinese music pieces.“I’m happy to see our Derformance can mix science and technology with traditional Chinese culture,” said Fang.

The band consists of three robot musicians, Yiiheng, Yaoguang and Kaiyang. They played three kinds of traditional Chinese instruments:the bamboo flute（笛子）Chinese harp（竖琴）and paigu, a set of Chinese drums（鼓）, at the concert.

Founded in 2018, the team behind the band is made up of students, teachers and graduates from Tsinghua University. The team’s chief scientist Mi Haipeng is a professor at the Academy of Fine Arts（美术学院）. He took part in the reaserch and development of a robot rock band when he studied in Japan. That experience made him considering making a Chinese robot band.

During the concert, the flute player Yuheng pressed the flute holes with its fingers while blowing the air into the pipe with changeable pressure to play the notes. Yaoguang plucked（弹）the Chinese harp’s strings with his fingers, with each one striking one string. Kaiyang imitated the movements of the human wrists（腕）to play the drums.

Mi said the music pieces in the concert were made for the robots to play. The robots’ shells and stage costurnes（戏服）were made with 3D-printing technology. He added that there are more performance plans for Moja in the future, introducing new music pieces. The team, meanwhile, would improve the musical expression of the robots.

21. Why was the night concert held? ________

A．To show the robot musicians.	B．To let people hear traditional Chinese music.
