He lets me use his house to hold events to raise money for youth at risk programs. The last time I was there he greeted me by saying, “I want to tell you why I let you use my house. It all goes back to a story about a young man who was the son of a poor horse trainer who would go from stable (马厩) to stable, farm to farm, training horses. As a result, the boy’s high school was continually interrupted (打断). One day in the last year of high school, he was asked to write a paper about what he wanted to do when he grew up.” “He wrote a seven-page paper about his goal of owning a horse ranch in great detail. He put a great deal of his heart into the project and even drew a detailed floor plan for the dream ranch. Then the next day he handed it in to his teacher. Two days later he received his paper back. But he got a low mark with a note that read, ‘See me after class.’” “The boy went to see the teacher after class and asked, ‘Why did I receive a low mark?’” “The teacher said, ‘This is an unrealistic dream for a young boy like you. You have no money. You come from a poor family. Owning a horse ranch requires a lot of money. There’s no way you could ever do it.’ Then the teacher added, ‘If you will rewrite this paper, I will reconsider your mark.’” “The boy went home and thought about it long and hard. He asked his father what he should do. His father said, ‘Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.’” “Finally, the boy turned in the same paper, making no changes at all. He wrote, ‘You can keep the low mark and I’ll keep my dream.’” 1．Which of the following statements is TRUE about Monty Roberts? A．He was born in a poor family. B．He received a good education. C．He is raising money for the poor. D．He is a horse trainer who owns a big ranch. 2．From Paragraph 3, we know Monty Roberts _____. A．was just a daydreamer B．decided to follow his father’s example C．expected the teacher to praise him D．had a great plan for his future 3．The teacher thought Monty Roberts’s dream was _____. A．strange B．great C．pleasant D．impossible 4．From the end of the text, we can infer that Monty Roberts was very _____. A．careful B．clever C．determined D．active B “I was dead for 67 minutes. It’s a miracle that I’m here today.” Those are the words of Bruce Richardson, who survived a cardiac arrest (心脏骤停) in July 2016 thanks to the quick actions of his friends and the first responders who refused to give up. It was an early summer morning, a typical Saturday. Bruce volunteered as usual in the community center. “I had no symptoms that there was any problem. It was a completely normal morning; I felt fine,” he shared. “I was visiting with friends. Then, I passed out. What happened next I know from what others have told me.” Bruce’s friend, Jack, had learned how to perform CPR, and he quickly began chest compressions. Another friend, Doug, dialed 911 and the operator walked him through compressions until first responders arrived. Once the ambulance arrived, the paramedic tried five times to restart Bruce’s heart with an AED．By this time, Bruce had been without a heartbeat for over 30 minutes, often when time of death is called. On the phone with an emergency room doctor, one of the paramedics was instructed to try two AEDs simultaneously (同时). It worked; Bruce’s heart began to beat again. Incredibly, he awoke the next day and was able to communicate. After a week, Bruce made a full recovery and left the hospital. Since Bruce’s cardiac arrest, he has since been able to resume a normal life with some differences. He now is a passionate CPR advocate. He has shared his story in the news, and last year he was a guest speaker at the Association’s Indianapolis Heart & Stroke Ball to encourage people to spread the message of CPR. Finally, Bruce shared his story in a video now being used to promote American Heart Association Hands-Only CPR kiosks installed around the country. 5．What made Bruce’s survival from a severe heart attack possible? A．The doctor’s first aid without delay. B．The instant actions of his friends and the first responders. C．His volunteer experiences in the community center. D．His friends’ proper guidance on performing CPR. 6．Why did Bruce share his story in a video? A．To advocate the application of CPR. B．To appeal to more people to volunteer. C．To share his struggle for a normal life. D．To enhance people’s awareness of fitness. 7．What can we learn from Bruce’s story? A．Hard work will pay off one day. B．Ease your mind when panic arises. C．Learning to live in the present matters. D．The knowledge of first aid counts. 8．What is the text? A．A research paper. B．A book review. C．A news report. D．A course advertisement. 七、七选五 How to Make Sure You Enjoy Your Trip A trip is a planned journey that one arranges in advance and whose main purpose is to search for adventure and to create a memorable moment.

He lets me use his house to hold events to raise money for youth at risk programs. The last time I was there he greeted me by saying, “I want to tell you why I let you use my house. It all goes back to a story about a young man who was the son of a poor horse trainer who would go from stable (马厩) to stable, farm to farm, training horses. As a result, the boy’s high school was continually interrupted (打断). One day in the last year of high school, he was asked to write a paper about what he wanted to do when he grew up.” “He wrote a seven-page paper about his goal of owning a horse ranch in great detail. He put a great deal of his heart into the project and even drew a detailed floor plan for the dream ranch. Then the next day he handed it in to his teacher. Two days later he received his paper back. But he got a low mark with a note that read, ‘See me after class.’” “The boy went to see the teacher after class and asked, ‘Why did I receive a low mark?’” “The teacher said, ‘This is an unrealistic dream for a young boy like you. You have no money. You come from a poor family. Owning a horse ranch requires a lot of money. There’s no way you could ever do it.’ Then the teacher added, ‘If you will rewrite this paper, I will reconsider your mark.’” “The boy went home and thought about it long and hard. He asked his father what he should do. His father said, ‘Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.’” “Finally, the boy turned in the same paper, making no changes at all. He wrote, ‘You can keep the low mark and I’ll keep my dream.’” 1．Which of the following statements is TRUE about Monty Roberts? A．He was born in a poor family. B．He received a good education. C．He is raising money for the poor. D．He is a horse trainer who owns a big ranch. 2．From Paragraph 3, we know Monty Roberts _____. A．was just a daydreamer B．decided to follow his father’s example C．expected the teacher to praise him D．had a great plan for his future 3．The teacher thought Monty Roberts’s dream was _____. A．strange B．great C．pleasant D．impossible 4．From the end of the text, we can infer that Monty Roberts was very _____. A．careful B．clever C．determined D．active “I was dead for 67 minutes. It’s a miracle that I’m here today.” Those are the words of Bruce Richardson, who survived a cardiac arrest (心脏骤停) in July 2016 thanks to the quick actions of his friends and the first responders who refused to give up. It was an early summer morning, a typical Saturday. Bruce volunteered as usual in the community center. “I had no symptoms that there was any problem. It was a completely normal morning; I felt fine,” he shared. “I was visiting with friends. Then, I passed out. What happened next I know from what others have told me.” Bruce’s friend, Jack, had learned how to perform CPR, and he quickly began chest compressions. Another friend, Doug, dialed 911 and the operator walked him through compressions until first responders arrived. Once the ambulance arrived, the paramedic tried five times to restart Bruce’s heart with an AED．By this time, Bruce had been without a heartbeat for over 30 minutes, often when time of death is called. On the phone with an emergency room doctor, one of the paramedics was instructed to try two AEDs simultaneously (同时). It worked; Bruce’s heart began to beat again. Incredibly, he awoke the next day and was able to communicate. After a week, Bruce made a full recovery and left the hospital. Since Bruce’s cardiac arrest, he has since been able to resume a normal life with some differences. He now is a passionate CPR advocate. He has shared his story in the news, and last year he was a guest speaker at the Association’s Indianapolis Heart & Stroke Ball to encourage people to spread the message of CPR. Finally, Bruce shared his story in a video now being used to promote American Heart Association Hands-Only CPR kiosks installed around the country. 5．What made Bruce’s survival from a severe heart attack possible? A．The doctor’s first aid without delay. B．The instant actions of his friends and the first responders. C．His volunteer experiences in the community center. D．His friends’ proper guidance on performing CPR. 6．Why did Bruce share his story in a video? A．To advocate the application of CPR. B．To appeal to more people to volunteer. C．To share his struggle for a normal life. D．To enhance people’s awareness of fitness. 7．What can we learn from Bruce’s story? A．Hard work will pay off one day. B．Ease your mind when panic arises. C．Learning to live in the present matters. D．The knowledge of first aid counts. 8．What is the text? A．A research paper. B．A book review. C．A news report. D．A course advertisement. A【答案】 1．A 2．D 3．D 4．C 【导语】本文是一篇记叙文。文章主要讲述了Monty Roberts坚持梦想不放弃的故事。 1．细节理解题。根据第二段中的“It all goes back to a story about a young man who was the son of a poor horse trainer who would go from stable (马厩) to stable, farm to farm, training horses.(这一切都要回到一个故事：有个年轻人，他是一位贫穷驯马师的儿子，父亲要辗转于各个马厩和农场驯马。)”和第五段中“You come from a poor family.(你来自一个贫穷的家庭。)”以及全文内容可知，这个年轻人就是Monty Roberts，他出生在一个贫穷的家庭。故选A。 2．细节理解题。根据第三段中“He wrote a seven-page paper about his goal of owning a horse ranch in great detail. He put a great deal of his heart into the project and even drew a detailed floor plan for the dream ranch.(他写了一篇七页的论文，非常详细地描述了自己拥有一座牧马场的目标。他在这个作业上倾注了大量心血，甚至为梦想中的牧场画了详细的平面图。)”可知，Monty Roberts对自己的未来有一个很远大的计划。故选D。 3．细节理解题。根据第五段中“The teacher said, ‘This is an unrealistic dream for a young boy like you. You have no money. You come from a poor family. Owning a horse ranch requires a lot of money. There’s no way you could ever do it.’(老师说：‘对于你这样的小男孩来说，这是一个不切实际的梦想。你没有钱，出身贫寒。拥有一座牧马场需要一大笔钱，你根本不可能做到。’)”可知，老师认为他的梦想是不切实际的，也就是不可能的。故选D。 4．推理判断题。根据最后一段“Finally, the boy turned in the same paper, making no changes at all. He wrote, ‘You can keep the low mark and I’ll keep my dream.’(最后，男孩交了同样的论文，一点也没有改变，他写道：‘你可以保留低分，我会保留我的梦想。’)”可知，Monty Roberts不受他人影响，坚持自己的志向，由此可知，Monty Roberts是一个非常坚定的人。故选C。 5．B 6．A 7．D 8．C 【导语】本文是一篇新闻报道。文章讲述了Bruce因心脏骤停67分钟后，在朋友和急救人员及时救助下奇迹生还，并致力于宣传CPR急救知识的故事。 5．细节理解题。根据第一段中“thanks to the quick actions of his friends and the first responders who refused to give up.(多亏了他的朋友们和急救人员拒绝放弃的迅速行动)”可知，是朋友和急救人员的即时行动让Bruce得以生还。故选B。 6．细节理解题。根据第四段中“Bruce shared his story in a video now being used to promote American Heart Association Hands-Only CPR kiosks installed around the country.(Bruce在一个视频中分享了他的故事，该视频现被用来推广美国心脏协会在全国各地安装的仅用手部CPR亭)”可知，Bruce在视频中分享故事是为了倡导CPR的应用。故选A。 7．推理判断题。根据第三段中“Bruce’s friend, Jack, had learned how to perform CPR, and he quickly began chest compressions.(Bruce的朋友杰克学过如何进行心肺复苏术，他很快开始进行胸部按压。)”可知，正是因为朋友掌握了急救知识并及时施救，Bruce才得以存活，由此可知急救知识非常重要。故选D。 8．推理判断题。文章以当事人的直接引语开篇，按时间顺序叙述事件经过(具体时间、地点、人物、救援过程、医院治疗及后续社会活动)，语言客观平实，具备新闻的时效性、真实性和叙事性特征，属于典型的新闻报道。故选C。 七、七选五 How to Make Sure You Enjoy Your Trip A trip is a planned journey that one arranges in advance and whose main purpose is to search for adventure and to create a memorable moment. Here are the steps on how to make sure your trip is enjoyable. Plan it well. Trips should be ideally planned to go well. 1 A checklist is helpful, making sure you’ve got all your needs. Pack necessities. Bring what you need. Trips are short journeys and belong to the sub-level of traveling. Pack only the things you need. 2 Be safe. To be cautious is smart. No matter what you are up to, surfing, cliff diving, snowboarding or scuba diving, it is always recommended to be safe. 3 Don’t be stubborn and put yourself in harm’s way when there are precautions. 4 You may see delays (延误), different cultures, lifestyles, foods, and even a shortage of cash sometimes — these are all what travel is about — experiencing things with a new perspective (视角). Once you expect to experience new things, you’ll be a happy traveler and free from stress. Save the memory. 5 This is not one of those regular days so you ought to save the moment. It will make your trip more enjoyable after all that craziness; you get something to review the good times. A．Travel with an open mind. B．Get prepared for everything new. C．This is all we expect from a trip. D．Seize the moment by taking pictures. E．It is important to wear protective equipment when necessary. F．It is easy to get tired if you have too many things in your package.

Trips should be ideally planned to go well. (做好计划。理想的旅行计划应该是顺利的。)”可知，这部分内容讲述的是旅行前的计划很重要。因此，本空要说跟“旅行前的计划”有关的话题，G选项“Take your time, a day or a week ahead to make a plan for your trip. (提前一天或一周，花时间来为你的旅行做个计划)”能承接上文，强调了提前规划的重要性。故选G。 2．由上文“Pack necessities. Bring what you need. Trips are short journeys and belong to the sub-level of traveling. Pack only the things you need. (打包生活必需品。带上你需要的东西。旅行是短途旅行，属于旅行的子层次。只打包你需要的东西。)”可知，这里建议只打包需要的东西。因此，本空要说跟“只打包需要的东西”有关的话题，F选项“It is easy to get tired if you have too many things in your package. (如果你的包裹里有太多东西，很容易感到累)”是对为何要少带东西的进一步解释，能承接上文，符合语境。故选F。 3．由上文“Be safe. To be cautious is smart. No matter what you are up to, surfing, cliff diving, snowboarding or scuba diving, it is always recommended to be safe. (要安全。谨慎是聪明的。无论你在做什么，冲浪、悬崖跳水、单板滑雪还是水肺潜水，我们都建议你一定要注意安全。)”可知，这部分强调参与任何活动时安全都是首要的。因此，本空要说跟“注意安全”有关的话题，E选项“It is important to wear protective equipment when necessary. (必要时穿戴防护装备是很重要的)”是对如何保持安全的具体建议，能承接上文，符合语境。故选E。 4．由下文“You may see delays (延误), different cultures, lifestyles, foods, and even a shortage of cash sometimes — these are all what travel is about — experiencing things with a new perspective (视角). (你可能会遇到延误、不同的文化、不同的生活方式、不同的食物，有时甚至会缺钱——这些都是旅行的真谛——以一种新的视角体验事物。)”可知，本段鼓励以开放的心态面对旅行中可能遇到的各种新事物，本空要说跟“开放的心态”有关的话题，A选项“Travel with an open mind. (以开放的心态旅行)”能够概括该段主旨，符合题意。故选A。 5．由上文“Save the memory. (保存记忆)”及下文“This is not one of those regular days so you ought to save the moment. It will make your trip more enjoyable after all that craziness; you get something to review the good times. (今天不是平常的日子，所以你应该保存此刻。在经历了这么多疯狂之后，它会让你的旅行更加愉快；你可以回顾一下美好的时光。)”可知，本段建议保存旅行中的美好记忆。本空要说跟“保存记忆”有关的话题，D选项“Seize the moment by taking pictures. (通过拍照抓住那一刻)”提供了一个具体的保存记忆的方法，即拍照，能承上启下，符合题意。故选D。 6．What surprised/amazed/astonished her 【详解】考查主语从句。引导主语从句，从句缺少主语，指物，故用what；表示“使惊奇”用动词surprise或amaze或astonish，her作宾语；根据后文was可知为一般过去时，从句谓语使用过去式形式。句首单词首字母大写。故填What surprised/amazed/astonished her。 7．in a league of his own. 【详解】考查固定短语。 句意：他声称自己对他们来说实在是太优秀了，独一档，无人能及。表达“独一档，无人能及”对应的固定英语习语是in a league of one’s own，作状语，且主语为he，故需用his替换one’s。故填：in a league of his own。 八. 完形填空 A 16-year-old girl was rescued after a hole she was digging in the sand caved in on her and buried her up to her neck.
