Twenty years of observations of chimpanzees (猩猩) reveal that older males choose to hang out with their long-term friends at the expense of other relationships.    The researchers studied 78,000 hours of observations made between 1996 and 2016 that followed the social interactions of 21 male chimpanzees between the ages of 15 and 58 years old. They classified the chimps' relationships depending on the amount of time they sat with others and groomed (梳毛) them. They then rated the various pairings as mutual (相互的) friendships, where both chimps seemed to enjoy the relationship; one-sided friendships, where one chimp was more keen to be friends than the other; and non-friendships, where neither chimp showed interest in the other.    When the scientists looked at the patterns of friendships, they found that the older chimps had more mutual friendships and fewer one-sided friendships than younger chimps. Another feature seen in older humans was also spotted in the chimps. As the males got older, their levels of aggression (挑衅) tailed off, meaning they started fewer fights and tended to intimidate others in their group less often.    The observations have left the researchers puzzled. According to an idea in psychology known as socioemotional selectivity theory, or SST, older humans prefer more positive relationships because they are aware time is running out. But many animal experts argue that chimpanzees lack the human sense of mortality (死亡), suggesting something else is driving the behaviour.    Robin Dunbar, a professor of evolutionary psychology at the University of Oxford, said in humans, the decline in social circles with age is due to declining social motivation to get out and meet people combined by lack of opportunity. In chimpanzees, as older males compete less for mates, they may focus on close, reciprocal (互惠的) relationships with trusted partners, she said.16. What do older male chimpanzees favour?A. Old friendships. B. New bonds. C. Greying hair. D. Wrinkled skin.17. How did the researchers draw their conclusion about chimpanzees?A. By turning to other scientists.B. By introducing a new concept.C. By forming relationships with them.D. By analyzing two decades' observations.18. What does the underlined word "intimidate" in Paragraph 4 mean?A. Threaten.B. Motivate.C. Defend.D. Accompany.19. According to Robin Dunbar, what accounts for declining social circles in chimpanzees?A. Awareness of time. B. Less competition for mates.C. Low motivation for socialization. D. Lack of the human sense of mortality.B    Sometimes it takes a crisis (危机) to bring friends together. When Hurricane (飓风) Maria went through the island of Cayo Santiago in 2017, the monkeys living there became kinder toward each other, according to a study published in the journal Current Biology.        The findings show the monkeys made more friends and became more patient to one another. Although the hurricane destroyed two-thirds of the plants on the "Monkey Island", the increased competition for resources caused the monkeys to become more amicable, which helped them widen their friendship circles.    "We expected the monkeys would use their closest partners to deal with the destruction of the hurricane and so would strengthen their existing relationships," said lead author Testard.    But that was not what happened. Instead, the monkeys built new relationships, rather than strengthening their old ones, which surprised the researchers. Monkeys that were the most lonely before the storm increased social connections the most afterward. The study showed that monkeys often befriended the friends of their friends. This "easy" way to making friends is often mirrored in human society.    The findings could also indicate how people might deal with the increasing threat of climate change. The monkeys are close evolutionary relatives to humans and share many features of their biology and behavior with human beings. The climate crisis has increased the likelihood of extreme weather events and natural disasters. Humans can learn a thing or two from studying how the monkeys cope with the unpleasant effects of climate change.    The main takeaway the study offers humans: go beyond your close-knit circle of friends and form a broader social network to survive tough times. "Our best friends can give us many things. But sometimes, what we need is a social network where everyone is just friendly enough," Testard says.20. What does the underlined word "amicable" probably mean?A. Attacking.B. Frightening.C. Friendly.D. Energetic.21. What shocked researchers about the monkeys in crisis?A. They shared the limited resources. B. They took advantage of old bonds.C. They established new relationships. D. Isolated monkeys were most popular.22. What does the last paragraph focus on about the study?A. Its process. B. Its result. C. Its purpose. D. Its significance.23. What can be a suitable title for the text?A. Ups and Downs of the Monkey IslandB. Connection between Humans and MonkeysC. A Crisis Leads to New Monkey FriendshipsD. Learn from Monkeys for Broader Social NetworkC    A young Dutch inventor is widening his effort to dean up floating(浮动的) plastic from the Pacific Ocean. He has developed a floating device(设备) to trap plastic waste moving iota rivers before it reaches the oceans.    Bogan Slat was just 18 years old when he invented a system for catching waste in the ocean. He also founded an environmental group called The ocean cleanup. Its purpose is to develop the system. In 2019, Slat showed the next step: a floating device called Interceptor. It removes pastie out of rivers.the device is powered by energy from the sun. "The 1,000 rivers are responsible: for shout 80% of plastic going into the world's oceans," said Slat. Three of the machines have already been used. Each machine costs about $775,600, but the cost might drop as production increases.    Since they were used, the machines have been doing very well, collecting the plastic bottles and all the rubbish in the rivers. According to Slat, it is necessary to close "the tap", which means preventing more plastic from reaching the oceans in the first place. He wanted to clean them all in the next five years. "This is not going to be easy, but if we do get this done, we could truly make our oceans clean again," said seal.    The device is designed to be safe in rivers. Its nose is shaped to change directions to keep it away from larger floating things. It works by guiding pastie waste into an opening in the front of the device. The waste is then called inside the machine: where it is dropped into containers. The device sends a text message to local operators that can come and empty it when it is full.24. What can we know about interceptor?A. It is being under test.B. It can help sort waste.C. It needs solar power to work.D. It is mainly used in the deans.25. What does "the tap" refer to in paragraph 3?A. The rivers.B. The machines.C. The oceans.D. The waste.26. What's the function of the device's nose?A. To empty the waste. B. To serve as containers.C. To ensure the devices safety. D. To send operators text messages.27. Where is the text most likely from?A. A diary.B. A guidebook.C. A novel.D. A magazine.D    When I was a little kid, one of my favorite things to do was going to the zoo. I recently heard that there are debates as to whether elephants should live in zoos or should they wander around free. My position is that some elephants should live in zoos for people to see.    Many experts say that elephants have a good life living in zoos. There are 78 zoos that exhibit elephants. Most zoos are taking the necessary steps to make living conditions better for the elephants. They are doing things such as replacing hard floors with sand or dirt. This makes it easier for them to wander around. Zoos are also expanding their elephant house to give the large animals more room to go around.    Zoos also protect endangered species. According to the World Wildlife Fund, in 2014 the total population of African elephants was around 700,000, and the Asian elephant population was around 32,000. The Asian elephants are on a path to dying out. Without zoos, they all are likely to disappear within our lifetime. The National Zoo plans to spend millions of dollars on a new Asian elephant habitat. That way, they can start their own group if the Asian elephants are gone.    There are people who want zoos to empty all of their elephant displays. If they decide to do so, it would take the chance to see elephants up close away from people. That could change the public's favorable opinion of elephants. National Zoo director John Berry says that allowing visitors to experience the elephants up close encourages people to care about endangered species. During one of my visits to the zoo, it was a very hot day. I was sweating a lot. Big Ben, the largest elephant on display, walked up to me and gently squirted(喷) my face with water from his trunk. Everyone was amazed at what he did. That was a very nice thing for Big Ben to do. I am sure that elephants are the nicest animals on earth. I wish all zoos would keep their elephant displays open to the public. I want all my friends to be able to experience what I did with Big Ben.    I feel zoos should follow all the necessary steps to keep elephants in zoos. I would raise money at my school if I thought it would help to keep elephants in zoos.28. According to the passage, what do we know about the Asian elephants?A. They are living in a new habitat.B. They are at the risk of disappearing.C. They prefer wandering on hard floors.D. They often squirt people's face with water.29. The underlined word "displays" in Paragraph 4 means _.A. productsB. tradesC. habitatsD. exhibitions30. What is the author's attitude towards keeping elephants in the zoos?A. Objective.B. Disapproving.C. Supportive.D. Doubtful.第II卷（非选择题）三、选词填空（共15分）A.color; B. bones; C.shape; D.cells; E.hide; F.dangerous; G.change; H.go; I.reflect; J.another; K.odd; L.amazingOctopuses are masters on disguise (伪装). They can change their appearance in less than a second. How do they do this? An octopus can disguise itself in three ways. One is by using   (1)  . An octopus's skin has special   (2)   called chromatophores. These cells are filled with yellow, brown, and red pigment (色素). When an octopus moves its muscles in a certain way, the cells produce colorful spots on its skin. Chromatophores can also   (3)   light. In blue light, for example, an octopus's skin will look blue. An octopus can also change its skin texture (皮肤结构). When the octopus moves its muscles, its skin can   (4)   unsmooth. It might then look like a plant, or coral. And   (5)   way an octopus disguises itself is by changing its   (6)  . Some, for example, roll their bodies into balls so they look like rocks. One type of octopus can change its form to look like other sea creaturesespecially   (7)   ones, such as sea snakes?Why are octopuses so good at disguising themselves? They have to be. The ocean is not a safe place for them. Because they have no   (8)   in their bodies, octopuses are like large pieces of meat. Many predators (捕食者) want to eat themand they can eat them whole. To survive, octopuses have developed the   (9)   ability to change their appearance very quickly in order to   (10)   from predators.四、阅读填空（共15分）阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。     Jim is an eight-year-old boy.
