One of the most 31 things about it is that I can watch animals in their natural environment. That’s what I like most about my job. My favourite place to take photos is the national park, which is famous for its different wild animals. And it is probably best known for its 32 runners — bears. Though heavy, these animals can run almost 64 kilometers per hour. Besides, they are also excellent swimmers. Last 33 in the park, I went through a forest. The view there was breathtaking. With 34 wind blowing, trees started to tum green and flowers danced from side to side. An eagle flew over the snow-capped mountains, which were mirrored in the still lake below. When I was focusing on 35 this wonderful scene, I suddenly felt that I was being watched. 36 , and with the camera still held to my eye, I turned a little bit, and a little bit… and froze. A bear! Only meters away from me. With water falling off its thick, brown hair, the bear 37 me. Time stood still as the bear and I both waited to see who would move first. My legs started shaking. Somehow, I 38 my finger to press the button. A second later, the bear turned and ran back into the forest. When I came to myself from the 39 , I looked at my camera. My most frightening but magical experience was now recorded forever in a single picture. From time to time I look at the photo as a reminder to show respect to all animals. In fact, we human beings are the 40 of their world. They live here long before we come. 31．A．comfortable B．amazing C．popular D．important 32．A．ugly B．furry C．large D．fast 33．A．spring B．summer C．autumn D．winter 34．A．strong B．gentle C．hot D．terrible 35．A．drawing B．reviewing C．copying D．photographing 36．A．Sadly B．Easily C．Slowly D．Hurriedly 37．A．stared at B．shouted at C．walked towards D．rushed towards 38．A．held B．pushed C．touched D．forced 39．A．trouble B．pain C．shock D．tiredness 40．A．friends B．visitors C．masters D．helpers 五、阅读理解 A Scientists have found that plants can make sounds. A scientist Lily Hadany and her team recorded tomato plants at different times. It showed that the plants made ultrasonic (超声波) sounds. Humans could only hear them with the help of a computer. They were noises like clicking (咔哒声) sounds. As the scientists studied the sounds, they began to find some interesting facts. Plants made different sounds at different times. They hardly clicked when they had enough water, but as the earth got drier, they clicked more and more. Scientists also found that plants made sounds when they got hurt. When scientists cut off a leaf from the plants, the plants also clicked more. But the clicking wasn’t the same as when the plants needed water. Some scientists trained a computer AI system to recognize (识别) the different kinds of clicking sounds. It was able to find the difference between plants that needed water and plants with cuts. It means that one day we may be able to use these sounds to figure out when it is in difficult time, and what problem it is having. That could be very helpful to farmers. The team’s finding changes our ideas about plants. As Dr. Hadany says, “Even in a quiet field, there are sounds made by plants, and those sounds carry information and may help us a lot.” 41．If you want to hear the sounds of plants, which of the following may you need? A． B． C． D． 42．How does the writer show the interesting facts in Paragraph ③? A．By giving examples. B．By telling stories. C．By asking questions. D．By using numbers. 43．What does “figure out” mean in Paragraph ④? A．Think about. B．Put out. C．Find out. D．Care about. 44．What can people do with the help of the team’s finding? A．Hear more beautiful sounds from different plants. B．Know how to recognize different sounds faster. C．Help farmers to know more about their plants. D．Stop people from cutting down trees. 45．What is the structure (结构) of the passage? A． B．C． D． B Trees are one of the oldest “citizens (公民)” of our earth. They keep our air clean, reduce noise pollution, improve water quality and provide food and building materials. Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy. When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruits. It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. The adult tree gives us shade, oxygen and natural beauty. It is also a great place for a tree house, or a place for us to read a book, listen to music and so on. If we give the adult tree proper care, it will go on to live healthily for many years. Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow (空心的) or part of it becomes dead, it provides a home to small animals and is a source of food for many other animals. In many ways, the life of a tree is similar to our own life experience. When we are looking at the life of a tree, we learn about that each period of life brings its own form of joy and challenge. Enjoy every minute of the life of the trees and take care of the trees! 46．What can it be used as when a tree becomes hollow? A．A home for small animals. B．Food for all animals. C．Shade and natural beauty for people. D．A place for a tree house. 47．Put the following in the RIGHT order according to the passage. ① Grow very rapidly.  ② Become a real adult. ③ Have large, deep green leaves. ④ Grow older and die. ⑤ Produce flowers and fruits. A．②①③④⑤ B．③⑤①②④ C．①③⑤②④ D．③①⑤②④ 48．Why should we enjoy every minute of our own life according to the passage? A．Because our life is becoming better and better. B．Because trees give us so much and make our world beautiful. C．Because the life of a tree is similar to our own life experience. D．Because each period of life brings its own form of joy and challenge. 49．What’s the best title for the passage? A．The Life of a Tree B．The Kinds of Trees C．The Mystery of a Tree D．The Advantages of a Tree 50．Which of the following shows the structure of the passage? A．①//②③④//⑤⑥ B．①②//③④//⑤⑥ C．①//②③④⑤//⑥ D．①②//③④⑤//⑥ C 配对阅读。左栏是五种动物遇到的生存威胁，右栏是七项人类采取的保护措施。请为每个动物问题匹配对应的解决方案，并在答题卡上将对应选项涂黑。选项中有两项为多余项。 51. People use lots of bamboo trees to build houses.

One of the most 31 things about it is that I can watch animals in their natural environment. That’s what I like most about my job. My favourite place to take photos is the national park, which is famous for its different wild animals. And it is probably best known for its 32 runners — bears. Though heavy, these animals can run almost 64 kilometers per hour. Besides, they are also excellent swimmers. Last 33 in the park, I went through a forest. The view there was breathtaking. With 34 wind blowing, trees started to tum green and flowers danced from side to side. An eagle flew over the snow-capped mountains, which were mirrored in the still lake below. When I was focusing on 35 this wonderful scene, I suddenly felt that I was being watched. 36 , and with the camera still held to my eye, I turned a little bit, and a little bit… and froze. A bear! Only meters away from me. With water falling off its thick, brown hair, the bear 37 me. Time stood still as the bear and I both waited to see who would move first. My legs started shaking. Somehow, I 38 my finger to press the button. A second later, the bear turned and ran back into the forest. When I came to myself from the 39 , I looked at my camera. My most frightening but magical experience was now recorded forever in a single picture. From time to time I look at the photo as a reminder to show respect to all animals. In fact, we human beings are the 40 of their world. They live here long before we come. 31．A．comfortable B．amazing C．popular D．important 32．A．ugly B．furry C．large D．fast 33．A．spring B．summer C．autumn D．winter 34．A．strong B．gentle C．hot D．terrible 35．A．drawing B．reviewing C．copying D．photographing 36．A．Sadly B．Easily C．Slowly D．Hurriedly 37．A．stared at B．shouted at C．walked towards D．rushed towards 38．A．held B．pushed C．touched D．forced 39．A．trouble B．pain C．shock D．tiredness 40．A．friends B．visitors C．masters D．helpers 五、阅读理解 A Scientists have found that plants can make sounds. A scientist Lily Hadany and her team recorded tomato plants at different times. It showed that the plants made ultrasonic (超声波) sounds. Humans could only hear them with the help of a computer. They were noises like clicking (咔哒声) sounds. As the scientists studied the sounds, they began to find some interesting facts. Plants made different sounds at different times. They hardly clicked when they had enough water, but as the earth got drier, they clicked more and more. Scientists also found that plants made sounds when they got hurt. When scientists cut off a leaf from the plants, the plants also clicked more. But the clicking wasn’t the same as when the plants needed water. Some scientists trained a computer AI system to recognize (识别) the different kinds of clicking sounds. It was able to find the difference between plants that needed water and plants with cuts. It means that one day we may be able to use these sounds to figure out when it is in difficult time, and what problem it is having. That could be very helpful to farmers. The team’s finding changes our ideas about plants. As Dr. Hadany says, “Even in a quiet field, there are sounds made by plants, and those sounds carry information and may help us a lot.” 41．If you want to hear the sounds of plants, which of the following may you need? A． B． C． D． 42．How does the writer show the interesting facts in Paragraph ③? A．By giving examples. B．By telling stories. C．By asking questions. D．By using numbers. 43．What does “figure out” mean in Paragraph ④? A．Think about. B．Put out. C．Find out. D．Care about. 44．What can people do with the help of the team’s finding? A．Hear more beautiful sounds from different plants. B．Know how to recognize different sounds faster. C．Help farmers to know more about their plants. D．Stop people from cutting down trees. 45．What is the structure (结构) of the passage? A． B．C． D． B Trees are one of the oldest “citizens (公民)” of our earth. They keep our air clean, reduce noise pollution, improve water quality and provide food and building materials. Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to protect themselves. For example, many trees grow thorns (刺) to warn animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy. When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruits. It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. The adult tree gives us shade, oxygen and natural beauty. It is also a great place for a tree house, or a place for us to read a book, listen to music and so on. If we give the adult tree proper care, it will go on to live healthily for many years. Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow (空心的) or part of it becomes dead, it provides a home to small animals and is a source of food for many other animals. In many ways, the life of a tree is similar to our own life experience. When we are looking at the life of a tree, we learn about that each period of life brings its own form of joy and challenge. Enjoy every minute of the life of the trees and take care of the trees! 46．What can it be used as when a tree becomes hollow? A．A home for small animals. B．Food for all animals. C．Shade and natural beauty for people. D．A place for a tree house. 47．Put the following in the RIGHT order according to the passage. ① Grow very rapidly.  ② Become a real adult. ③ Have large, deep green leaves. ④ Grow older and die. ⑤ Produce flowers and fruits. A．②①③④⑤ B．③⑤①②④ C．①③⑤②④ D．③①⑤②④ 48．Why should we enjoy every minute of our own life according to the passage? A．Because our life is becoming better and better. B．Because trees give us so much and make our world beautiful. C．Because the life of a tree is similar to our own life experience. D．Because each period of life brings its own form of joy and challenge. 49．What’s the best title for the passage? A．The Life of a Tree B．The Kinds of Trees C．The Mystery of a Tree D．The Advantages of a Tree 50．Which of the following shows the structure of the passage? A．①//②③④//⑤⑥ B．①②//③④//⑤⑥ C．①//②③④⑤//⑥ D．①②//③④⑤//⑥ C 配对阅读。左栏是五种动物遇到的生存威胁，右栏是七项人类采取的保护措施。请为每个动物问题匹配对应的解决方案，并在答题卡上将对应选项涂黑。选项中有两项为多余项。 51. People use lots of bamboo trees to build houses.
