I lived in a beautiful house with the beautiful surroundings in Puerto Rico. There was one particular thing I loved and it was a huge tree that was in my backyard. As a child, I used to climb the tree every day. Every time I went, I climbed higher and higher, reaching new branches, obstacles, and pathways on my way up. One day, I reached the top and I could see my island. I felt I was on top of the world, and nothing could stop me. Then, there was the day that seemed like the end of my life. This specific day changed my life forever.It was a nice summer day. After breakfast, my family headed to the park to see my baseball game.In the evening we went to a carnival (嘉年华) in my town. My grandma was selling blankets under a tent. Suddenly, the mood of the day changed when my parents took me to my grandma's tent. Still to this day, I remember the exact words my dad said to me, “Son, how would you like to move to the United States?”I couldn't believe what he said. I then ran away from him as the tears rolled down my cheeks. My perfect life was being taken away from me.Two weeks later, we arrived at New York in late July, and my aunt and uncle drove us to Springfield，Massachusetts where we lived for seven years. Once we got there, I met my mom's family for the first time. September came and school started. I was afraid to go to a new school and make new friends. Most kids ignored me and some tried to talk to me, but I couldn't understand them or say anything. My first year in the United States was not fun or easy but I worked hard and got through it.Now that I'm grown, I look back on the journey that I've been through: living in a new place with no friends, new language, and new schools. Despite all those problems, I still remembered that special tree. That tree taught me to never give up and reach higher. I have beaten every difficulty that I have met in life and I just kept moving forward. My perfect life was never taken away from me; it has just started.24.When the author was a kid, he _________.A. thought his life was very pitifulB. expected to live in a beautiful houseC. dreamed of traveling around the worldD. enjoyed the pleasure of climbing a tree25.Why does the author mention the baseball game and carnival in the passage?A. To compare life with that in America.B. To introduce his family tradition.C. To show he didn't like studying.D. To state his daily life routine.26.Paragraph 3 mainly tells us about _________.A. the family that he had met beforeB. his new friends in Springfield, MassachusettsC. the living conditions when he arrived in AmericaD. his difficult experiences during the first year in the US27.The author has realized that to live a perfect life is _________.A. to never give upB. to always make new friendsC. to forget all problemsD. to remember sweet memoriesCRetired judge Davison hated all the quiet. Evy, his wife of 66 ears, had passed away, and he was lonely and sad in the months after her death. But he knew how to beat those feelings; he decided to build a pool.Davison contacted a family-run company in Hopkins, Minnesota, that had built a pool for his previous house 40 years ago. “They did such a great job before and were still in business, so they came out and planned it,”Davison said.Kevin, who works on new pools for the company, helped Davison with everything, from initial planning and completing contracts back in March to teaching him how to filter the water once the pool was finish in July.“If You build it, they will come,”he thought. He invited all the neighborhood kids over to swim. Now it’s not so quiet anymore.He hears the sounds of laughter and splashing as he sits on a chair in the shade, watching happy children play in his backyard.“I knew they’d come.”94-yvear-old Davison told KARE-TV.Neighbor Jessica thought the judge was joking when he talked about putting in a pool until she saw the work starting. Now she and her four kids have been regulars since the pool was finished in July.“It’s him spreading joy throughout our neighborhood for these kids.”Jessica said.Davison’s pool includes a diving board and reaches nine feet in the deep end under the board. It’s especially welcome in a town that doesn’t have a public outdoor pool.Although Davison has three adult children, he doesn’t have any grandchildren.Jessica says she’s told him, “You kind of adopted our whole neighborhood of kids. These are your grandkids.”The judge’s rules require that a parent or grandparent stay while the children are swimming. Once the kids leave. he likes to swim, too.Davison tells KARE-TV that he realizes that putting in the pool didn’t make a lot of financial (经济的) sense for an old man. But that didn’t matter to him.“I’m not sitting by myself looking at the walls.”he says. “What else would you think of doing where you could have a whole bunch of kids over every afternoon?”The 94-year-old judge now hears laughter all day as he watches children splash in his backyard pool.28.Why did Davison build a swimming pool?A. To remember his dead wife.B. To earn some money for a living.C. To fight against his loneliness.D. To please the kids in the neighborhood.29.What does the underlined word “they”in Paragraph 4 refer to?A. The neighborhood children.B. His three adult children.C. Reporters from KARE-TV.D. The workers who built the pool.30.What rules do children have to follow while swimming in the judge’s pool?A. They shall wear life jackets.B. They shall be in company with the adults.C. They shall receive some training.D. They shall get their parents’permission.31.What can we learn from the story?A. Action speaks louder than words.B. True success comes from spiritual riches.C. The value of life lies in respect and love.D. One’s search for happiness brings others great joy.DWhere can you find a nice place to relax on holiday for both you and your children? Well, I suggest you try the beautiful and green Isle of Wight (IOW). The Isle of Wight is one of the main tourist attractions. Here is some information on a few of the attractions on the IOW.Dinosaur IsleIt is located in Sandown, a seaside town on the southeast coast. It’s a large, lovely museum, both fun and educational. Here you can see a large fossil collection of all kinds of dinosaurs, as well as a gift shop. You can walk into the past and then the future, learning about the history and the development of the civilization of dinosaurs that lived 120 million years ago.Robin Hill Country ParkThe park is in the beautiful countryside, and is suitable for children’s parties and games. It has five new gardens, and offers great opportunities to see and take pictures of the rare red squirrels.The West of the WightHere we have the Marine Aquarium, the Archaeology Exhibition and the Model Railway. They offer another opportunity to combine fun with learning. This is a great place to see ancient boats crossing the narrow strait between the island and the mainland.The Wight Bus MuseumThis museum is run completely by unpaid volunteers. It has a bus collection stored in what was once a warehouse(仓库). Most of the buses in the museum date back to around the 1910’s.With all of these choices, what are you waiting for? IOW Tourism welcomes you!32.In Robin Hill Country Park, children can NOT .A. have parties.B. buy gifts.C. play games.D. take pictures.33.It can be learned from the passage that .A. there are five new gardens on Dinosaur IsleB. visitors can drive buses in the Wight Bus MuseumC. those running the Wight Bus Museum work for freeD. on Dinosaur Isle we can learn about all kinds of animals34.The purpose of this passage is to .A. show the development of tourism on the IOWB. advise readers how to relax on holidaysC. attract readers to come to the IOWD. tell readers what is worth visiting35.You can read this article in a .A. travel magazineB. science journalC. book reviewD. film advertisement第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

2020年春四川省叙州区第一中学高一期末模拟考
2020年春四川省叙州区第一中学高一期末模拟考试In China, there are more and more people leaving the countryside to hunt for jobs in the cities, because the countryside is much poorer than the city, and often there isn’t much work there. Services such as hospital and transport are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.But in the big cities of Europe like London or Paris, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt of the city, and they are tired of the crowded streets, crowded trains and buses. They don’t want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there. So they move out of the cities. Some don’t go very far, just a little way out of the city, to the towns near the cities. Other people move to the real countryside with sheep, cows and green fields. There they start new lives and try to make new friends.Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it is a big mistake. They don’t make so much money and there isn’t much work to do.

The park was empty except for little Carter Brunell，who was there with his mother celebrating his fifth birthday.Carter is on the autism spectrum（自闭症）. Big groups of older kids can make him nervous，so his mom，Kristen，was fully prepared to get him out of there. But she wasn't prepared for what happened next.Gavin led the way and the others followed. The only surprise was that Gavin didn't start trouble. He started a friendship. "Gavin is just going around with Carter and making him feel special. And the rest of his friends then started singing Happy Birthday to him，"Kristen said，“That really blew me away，because I just saw the kindness in the world. And I wanted Carter to have a good birthd ay. ”It was such a great birthday, and such a kind deed, even the local police department responded. They decided to hold a pizza party for them. But here's the best part: Since their first meeting, Gavin and his friends have continued to play with Carter.As for the moms, this was the sweetest moment.

Whenever I was “bad”, you'd shake your finger at me and ask, “How could you?”--but then you'd give up, and roll me over for a belly scratch and I believed that life could not be any more perfect.My housetraining was a long process, because you were terribly busy, but we worked on that together. We went for long walks, runs in the park and car rides. We stopped for ice cream. I took long naps in the sun waiting for you to come home at the end of the day.Gradually, you began spending more time at work and on your career, and more time searching for a human mate. Eventually, you fell in love. She, now your wife, is not a dog person, but I still welcomed her into our home. I was happy because you were happy. Then the human babies came along and I shared your excitement, I was fascinated by their pinkness, how they smelled, and I wanted to mother them too. Your wife was afraid I would bite them. But nevertheless, as they began to grow, I became their friend.Now, you have a new job in another city and you and they will be moving to an apartment that does not allow pets. You've made the right decision for your “family”, but there was a time when I was your only family.I was excited about the car ride until we arrived at the dog pound. It smelled of dogs and cats, of fear, of hopelessness. You filled out the paperwork and said, “I know you will find a good home for her.” They shrugged and gave you a pained look. The children were in tears as they waved me g oodbye. And “How could you?” were the only three words that swept over my mind.Is it better to live with hope or without hope? At first, whenever anyone passed my pen , I rushed to the front, hoping it was you, that you had changed your mind and that this was all a bad dream.My beloved master, I will think of you and wait for you forever.

If you know your computer will save information, why do you store it in your own personal memory, your brain?Professor Betsy Sparrow, together with her research team, has carried out some experiments in a recent study, wanting to know how the Internet is changing memory. In the first experiment, they offered people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.In another experiment, the researchers gave people facts to remember, and told them where to find the information on the computer. The information was in a specific computer folder( 文件夹 ). Surprisingly, people later remembered the folder locations better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called “transactive memory(交互记忆)”.According to Sparrow, we are not becoming people with poor memories as a result of the Internet.Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn’t mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.32.Why does the text begin with two questions?A.To make a comparison.B.To introduce the main topic.C.To show the author’s attitude.D.To list some examples.33.What can we learn about the first experiment?A.The Sparrow’s team typed the information into a computer.B.The two groups remembered the information equally well.C.The first group did not try to remember the information.D.The second group did not understand the information.34.What do people usually do in transactive memory?A.They remember how to find the information.B.They organize information like a computer.C.They change the quantity of information.D.They bear the information in mind.35.What is Sparrow’s attitude towards the influence the Internet has on people’s memory ?A.Negative.B.Passive.C.Objective.D.Doubtful.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

“中国提出的经济主题和议题非常契合当前世界的需要，可谓恰逢其‘时’”，知名智库欧亚问題研究所专家汉内斯•德凯泽如此评价。
随着经济全球化深入发展，世界各国利益和命运更紧密地联系在一起，很多问題不再局限于一国内部，很多挑战也不再是一国之力所能应对。
因此,全球治理体现为一种秩序性追求，核心是如何在制度上摆脱集体行动的困境.“世界那么大，问題那么多，国际社会期待听到中国声音、看到中国方案，中国不能缺席。
”有人注意到,在法国近代的《人权宣言》及第二次世界大战后联合国发布的《人权宣言》中，都引用了《论语》“己所不欲，勿施于人”的论断.事实上，无论是“四海之内皆兄弟”的大同理想，还是讲信修睦、善待他人的平和禀性，在中国人的世界观念中，和谐共存是最基本的关犍词。
从“仁者爱人”“民惟邦本"“言必佶，行必果”到“君子喻于义”“和而不同”“出入相友，守望相助”，诸多中国百姓日用而不觉的处世之道,如同一股清流，为完善当前全球治理注入了新内涵,提供了新思路。
于强烈的纷争对抗中寻找共同点,引导各方换位思考,巧妙化解分歧，直到最终达成各方满意的结果—-在不少国际观察人士眼中，不管是调解地区争端,还是倡导解决危机，中国人的方法总能“令人耳目一新”.灵活、务实的解决方案背后，是中国对支配性、排他性思维的坚决摒弃，对和衷共济、合作共赢理念的坚定支持。
