    So what is rewilding
    Imagine our natural homes growing instead of shrinking. Imagine species (物种)diversifying instead of declining. That’s rewilding. Rewilding is ecological restoration. Rewilding offers hope for wildlife, humans and the planet.
    Why is rewilding important and necessary
    ●Our natural ecology is broken. The places where you would expect wildlife to exist have been reduced to wet deserts. The seabed has been destroyed and there have been no livingcreatures any more.
    ●Our wildlife is disappearing. Many wonderful species have declined over the past century. We’ve lost more of our large animals than any European country.
    ●We need keystone species. These vital species, including top predators (食肉动物), drive ecological processes. Their loss has worsened our living systems.
    ●Nature looks after us. Good natural ecology can provide us with clean air and water, prevent flooding and store carbon. Rewilding can leave the world in a better state than it is today.
    What are challenges
    As a long-term project, our “rewilding britain” has its challenges. Many people are notinterested, because we have got used to the lack of native forests. Many farmers oppose the idea. They thought it a crazy idea to bring back predators because they would start killing farmanimals. It takes time to educate them. Above all, we need money! So we need your help!

    Brazil, the largest country in South America, is famous for the Amazon rainforest and soccer. But on the hottest days, people travel there for another reason – the Carnival. Full of excitement and fun, the Carnival is held annually in February or March. This year, the celebration runs from March 2nd to 9th .
    It is a wild festival of food, music and dance. The word “Carnival” comes from the Portuguese “Carne Vale”, which means “farewell to meat”. In the early 1600s, the Portuguese brought European traditions to Brazil. Then they started their own carnival with dances and music, which were inspired by black people brought there by the slave trade.
    With its beautiful floats (花车), attractive clothes and happy people, the Samba Parade is the most fantastic event of the Carnival. The Sambadrome is a special stadium for the Carnival in Rio de Janeiro with 80,000 seats where people can sit and enjoy the festival. Samba is said to be the soul of Rio. “This is where the passion for samba lies – the atmosphere is electric as even the oldest men and women sing and dance to the music,” travel guidebook Lonely Planet noted.
    Top samba schools stand out in the main parade, with fantastic parades of floats and thousands of dancers. The parade goes on until dawn. The schools base their performances on certain themes from Brazilian history or on social and environmental problems, such as that of the Amazon rainforest.
    Besides fun street parties, colorful costumes and energetic music, Carnival also offers plenty of tasty street food, such as Quindim – a dessert made of egg yolks and sugar.
    Overall, it is traditionally a time to go a bit crazy with eating, dancing and dressing up.
    21. What is true about the Carnival in Brazil
    A. It is annually celebrated from March 2nd to 9th.
    B. It has attracted a large number of people.
    C. It is held for people to stop eating meat.
    D. It was brought to Brazil by black people.
    22. It can be inferred that Samba is popular because _______.
    A. it brought European tradition
    B. it highlights top Samba Schools
    C. it represents Brazilian passion
    D. it reflects Brazilian history
    23. What is the main purpose of the passage
    A. To tell the history of European settlers.
    B. To attract more visitors to Brazil.
    C. To introduce the Carnival in Brazil.
    D. To show the attraction of Samba.
    B
    Something very strange and mysterious was going on in Sesemann’s house. Every morning, when the servants went downstairs, they found the front door wide open. During the first few days that this happened, every room and corner was searched in great alarm to see if anything had been stolen, but not a thing in the house had been touched. The door was doubly locked at night, and for further security the wooden bar was fastened across it; but it was no good – next morning the door again stood open. One servant even claimed he had seen a white figure standing at the top of the steps and then all in a minute it disappeared.
    Mr. Sesemann told his old friend, a doctor, what had happened in his house. That evening they decided to wait for the ghost. One o’clock struck. There was not a sound. Suddenly the doctor lifted his finger. “Hush! Don’t you hear something” They both listened, and they distinctly heard the bar softly pushed aside and then the key turned in the lock and the door opened. They stepped into the hall.
    “Who is there” thundered the doctor in a voice that echoed through the hall, as the two men advanced with lights and weapons towards the figure. It turned and gave a low cry. There stood Heidi, with bare feet, staring with wild eyes and trembling from head to foot. The two men looked at one another in surprise. “Child, why did you come down here” said Sesemann. White with terror, and hardly able to make her voice heard, Heidi answered, “I don’t know.” The doctor gently took the child by the hand upstairs.
    Then the doctor sat down besides her and asked her some questions in a kind voice. Later he went downstairs. “Sesemann,” he said, “let me first tell you that the child is a sleep-walker; Secondly, the child is consumed with homesickness. Something must be done at once.”
    24. The door in Sesemann’s house was doubly locked at night in order to ___________.

    We were silently waiting on the platform in the late afternoon. There he was, my 80-year-old grandfather with his silvery hair. And there I was, a teenage girl in my jeans and T-shirt. His aged but still clear blue eyes were taking in the scene as I wondered how I was going to get through the next two days. Why did I ever agree to accompany my cranky grandpa on a train ride from New York to Georgia
    No one else wanted to be the fellow traveler since my grandfather refused to fly. In contrast, I loved to fly since I wanted to get to the destination as quickly as possible. No matter what anyone told my grandfather about the comfort and safety of flying, he refused to book a flight, saying, “It’s not just the trip; it’s the adventure of getting there.”
    With my first step onto the train, the journey was already different from what I expected. The train was modem and filled with friendly travelers. We settled into the club car, where we could enjoy food and drinks while watching the scenery pass. Instead of listening to my music, I became a willing audience and learned family history that I had never had the time or patience to learn. With teary eyes, he told me that going to family events was hard for him since my grandmother died. It always made him think about those who were no longer with us. For the first time I felt I understood him. I gained a new appreciation for our time together.
    In this fast-paced world, we often miss important moments. There is great significance in listening to elders who offer a piece of their history and experience. I may be more open to opportunities to stay with my grandpa. Life isn’t just about the destination; it’s about the journey.
    24. What does the underlined word “cranky” in paragraph 1 mean
    A. Health. B. Strange C. Selfless. D. Outgoing.
    25. What did the author think of the journey at first
