Have you ever been to any exciting theme parks at home and abroad? If you want to explore and experience, here are some incredible ones for you to choose from. Busch Gardens Williamsburg Located in Virginia, USA, this theme park has some of the highest-related thrilling rides in the world. The park’s famous roller coasters include Apollo’s Chariot, Alpengeist, Griffon, Loch Ness Monster and Verbolten.

The park has 40 thrilling rides, including a world-famous wooden roller coaster, and many other attractions such as an African hunting ride, a zoo, indoor and outdoor water parks, shows and more. Blackpool Pleasure Beach This Lancashire amusement park is one of the most visited theme parks in the United Kingdom.

(B) Whether you are traveling to a different country for business or study, you must always be prepared to experience and overcome cultural differences and language barriers. Here are a couple of tips on how to help bridge the gap between cultures. Every country in the world, old or new, has a rich and storied history. They celebrate their own holidays, cook national dishes, listen to their own styles of music and wear clothes appropriate for their culture. Take some time to learn the history, art and customs of the country you’ll be visiting. Showing your knowledge of the local customs and history will make those around you realize you truly care about their culture. Language are hard to master. You spent years in grade school learning all the grammar and intricacies (复杂) of English. Why not spend more time learning a whole new language — especially when so much of the world speak English already? Even if you can only recite a couple of key phrases, it shows that you’re making the effort to bridge the cultural gap. Unfortunately, no matter how much you research a country or how well you know the language, there will always be some culture shocks and confusion. Words, actions or gestures that are not offensive (冒犯的) to us can be very offensive to someone from another culture. When this occurs, it is important to stay patient. Working through these frustrations together will lead to a smarter and stronger bond between you and your friend from another culture. When I learn a new language, or study the history of a culture I’m unfamiliar with, I think of it as exploring a new world. There are so many things that make each culture unique. You have to be open to trying and learning new things in order to fit in well in another country. Always try to think about how they see things from their cultural perspective. All of this being said, there are so many similarities between people of all nations. We all laugh at the same physical comedy, groan when we have to clean up our pets’ messes and cry when we lose a loved one. After all, we are all humans. 24. What are you supposed to do to show your efforts to fit in? A. Develop an optimistic attitude. B. Do research into the new culture. C. Publicize its unique cultures. D. Clear all the barriers in the way. 25. What does the author think of culture shocks? A. Overwhelming. B. Abstract. C. Depressing. D. Unavoidable. 26. How does the author encourage us to be in paragraph 5? A. Open-minded. B. Suspicious. C. Ambitious. D. Insightful. 27. What is the most suitable title for the article? A. Participating in cultural communication. B. Stepping out of your comfort zone. C. Exposing yourself to different cultures. D. Bridging the Gap between Cultures. ( C ) We’ve all left the house and found ourselves wondering: Did I shut the door? Did I turn off the kitchen lights? If these moments of doubt crop up a lot in your day-to-day life, a smart home system could save you a great deal of stress and worry. The primary advantage of a smart home is that you can flexibly control and automate your smart house technology. Using an application on your smartphone or tablet, you can control everything like your lighting, heating and sound system with incredible convenience. If your mobile device isn’t at hand, your smart home is equipped with other ways to control your smart house technology — including voice control. Smart lighting control is one of the most common applications of smart house technology. Smart lights can be controlled individually from the comfort of your sofa or combined into groups so that you can set the mood — whatever kind of atmosphere you want to create. In a smart home, you can see who’s at your door before you open it — and even communicate with visitors from your garden, the supermarket or your office. Modern smart house technology makes your door communication system mobile and gives you that extra level of peace of mind when unexpected visitors arrive. You can also operate your door communication system remotely and invite guests in before you get home. Smart blind (卷帘) systems are designed to improve comfort, convenience and security. With smart house technology, you can adjust your blinds to suit your needs by using intelligent wall switches to give you a little more privacy. Depending on the level of the sun, the outdoor temperature and the time of day, your smart house technology can also provide the right amount of shade in your rooms to reduce the burden on your air conditioning system and save energy. Intelligent home control technology is developing at a rapid pace. No matter whether you are in new or old buildings, in houses for rent or in your own home, modern home technology is rapidly becoming the standard and will soon naturally enrich your daily life. 28. What is the primary advantage of a smart home? A. Flexible home control. B. Personalized designs. C. Modern conveniences. D. Comfortable atmosphere. 29. What can we learn from paragraph 4? A. Remote working will become a reality. B. Door communication goes mobile. C. Security and comfort can be ensured. D. Visiting a smart home is efficient. 30. What is the author’s attitude to modern home technology? A. Favorable. B. Critical. C. Doubtful. D. Concerned. 31. What is the purpose of the text? A. To predict remarkable life prospects in the near future. B. To advocate technological innovation and application. C. To introduce some smart house technology features. D. To persuade us to embrace technological advances. (D) For years, the discussion on the development of synthetic (合成的), lab-grown organs (器官) has been a major talking point. Many see it as a worrying subject, with ethical (道德的) understandings. Others, though, see the process of lab-grown organs as an essential part of making sure we can give everyone the help that they need. However, advancement in the process has been a slow-burning development. The University of Pittsburgh, though, has been working on a process to help make sure that lab-grown livers (肝脏) could be created. They have been using machine learning and synthetic biology in combination with one another to try and find the ideal solution to the creation of entirely safe lab-developed livers. The aim is to help speed up the process of creating a human liver with real blood and bile (胆汁) management systems. So far, though, the process is still very much in the development stage. The testing in mice, though, did show that when mice with failing or failed livers were given the lab-grown alternative, their lifespan was increased. While it cannot be said for certain that it works without qualification, there is already a clear interest in the use of lab-grown organs. The aim is simple — find a way to avoid having to wait on the loss of another human life to save a sick life. With lab-grown organs, that could become a reality in the future. Testing, however, is going to be a long-term process; even with the progress made, real-life usage is still some way off. Are lab-grown organs a realistic proposition? It certainly appears to be the case. Indeed, the synthetic biology and machine learning combination in Pittsburgh has produced some of the most positive, promising results seen in some time. The hope is that they can continue to grow and get better over time, and that the progress can continue to develop to the right standard without any complications or delays. If lab-grown organs have become a talking point that you find worrying, then the progress being made in Pittsburgh might assuage some fears. You should absolutely take a closer look at lab-grown organs processes being developed, though, as the progress being made in Pittsburgh is the most promising news in some time. 32. What is discussed in the article? A. Whether lab-grown organs can be realistic. B. How we can cure failing organs. C. Where technology will eventually lead us to. D. Why we should develop organs. 33. What does the testing in mice indicate? A. The process consumes time. B. Artificial organs will soon be popular. C. The lab-grown liver can work. D. Previous doubts are just unnecessary. 34. What does the underlined word in the last paragraph probably mean? A. Confirm. B. Strengthen. C. Ease. D. Reveal. 35. What do you know about the work on lab-grown organs in Pittsburgh? A. It proves the significance of organs. B. It has actually got nowhere so far. C. It has met with intense oppositions. D. It is going slowly but promisingly. 第二节（共5个小题；每小题2.5分，满分12.5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。选项中有两项为多余选项。 Body language around the world It is said that our body language exhibits information about our thoughts and feelings. But the implied meaning of these common signals we use every day can mean something wildly different in another culture. 36 From them, you can know how to integrate and what to avoid. Greetings 37 Handshakes and hugs are common practices in Western societies in places like the US and UK, but in parts of Europe such as France and Italy, handshakes are a slightly more personal greeting. It’s common to linger for longer, which some visitors may find uncomfortable. Hand and arm gestures As standard, Italians use their arms and hands to gesture constantly while talking, whereas in Japan, this is considered bad manners. If you’re in Belgium or Northern Italy, be sure to avoid brushing your hand underneath your chin when speaking — it is a vivid way to tell someone to go away! 38 Well, hopefully you haven’t visited Greece or Sardinia yet, where it is considered to be as rude as a middle finger signal in the West. Head and movements In many parts of Eastern Europe, the standard nodding and shaking signifying yes and no respectively are switched, which can, of course, get very confusing. In Japan, staring too long is considered rude, invasive or even an act of aggression. Our special gesture, though, has to be this traditional signal from Tibet, China. If someone is sticking their tongue out at you in the street, all may not be as it seems! 39 But in Western cultures, it is considered playful, silly or even bad-mannered. All in all, body language plays a significant role in communicating with people from other cultures. 40 1 A. It can send signals stronger than words. B. My body utters when I try to hide something. C. In fact, it’s a way of demonstrating respect. D. In the UK and Australia, the sign means victory. E. Do you think the thumbs-up sign a universal gesture for “great”? F. Here is an introduction to the most unusual examples across the globe. G. In various parts of India, it’s common to greet one another by touching feet. 第三部分：语言运用（共两节，满分30分） 第一节：完形填空（共15小题；每小题1分，满分15分） 阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项，并在答题卷上将该选项标号涂黑。 You never know when a chance encounter will change your life.

One of the most obvious things is their skills in 56 (manage) time. Instead of being slaves to time, they have learned how to make time work for them. And they do this in a few different ways. For one, they value 57 (efficient). On top of that, they stay focused on one single task at a time. Whether it’s books, courses or any other informational content, high achievers spend time every day working to learn something new and 58 (sharp) their skills. Even if they only learn one new thing or a way of thinking from a book, they know that it wasn’t 59 waste of time. Any and all knowledge is extremely valuable to them. While most people will turn and run the other way in the face of adversity, or let their 60 1 (struggle) consume them, high achievers recognize them as an opportunity 61 (grow) and get better. They embrace them, they welcome them, they learn to love them 62 they understand that fights are a privilege. All high achievers know that every detail 63 (matter). This applies to the tiniest details 64 (consider) to be insignificant. But how you do one thing is how you do everything. That’s why you’ll never see high achievers miss one speck of dust. They’ve learned to take pride in the details. It’s a huge part of 65 separates them from everybody else. 第四部分：写作（共两节，满分40分） 第一节：应用文写作（满分15分） 随着科技发展，各种新型的科技产品不断涌现并进入了大家的学习和生活，现请你给校英文报“科技生活”栏目就你喜爱的某一产品写一短文，内容要点包括： 1. 产品及你的使用； 2. 你对产品的评价。 注意： 1. 词数80左右； 2. 请按如下格式在答题卡的相应位置作答。 My Favorite Sci-tech Product 第二节：续写（满分25分） 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。 “I don’t know what to be for Halloween tonight,” said Marcus to his family sitting around the table. It was lunchtime already, and Marcus had spent days trying to pick a costume. He didn’t want to be the same things his friends had chosen. So he was left empty-handed with only hours to go. “What about a robot?” asked his sister. “That would be hard to do now,” said Marcus. “All the best costumes are already taken.” “What about the zombie costume from last year?” asked Dad. “It might still fit you.” “No, they aren’t cool anymore,” answered Marcus. “I don’t know what the problem is,” said his mother. “When I was a kid, we would just make a costume out of stuff we had around the house. You know, throw a sheet over our heads and go out as a ghost, or put on a witch’s hat and grab the broom.” Marcus sighed. He just could not make his mind up. He reached his hand out to take a sip of juice. By accident, Marcus knocked his glass of grape juice all over the table. “Oh, what a mess! I don’t know if this stain (污渍) will come out.” Mom cleared some of the glasses and plates away to gather up the white tablecloth. It was now marked with purple spots. She threw it into the washing machine in the laundry room (洗衣间). “I’m sorry, Mom,” said Marcus. He knew it was a clumsy mistake. “It’s okay, honey. Accidents happen. Finish your lunch now. It’s time to carve the pumpkin.” Marcus and his sister took the last bites of their sandwiches. Then they began the messy job of scooping out the pumpkin seeds so Dad could carve it into a Jack-o’-lantern. Marcus still had no ideas for a costume. Maybe he should just give up on trick-or-treating this year. When the laundry was finished, Mom pulled out the tablecloth and saw the purple spots were still there. “I guess I’ll throw it away,” she said. “I wonder if I can use it for anything else.” 注意： 1. 续写词数应为150左右； 2. 请按如下格式在答题卡的相应位置作答。 “I have an idea!” Marcus said, taking the large tablecloth from his mother. As Marcus stood in front of the mirror, a big smile spread across his face.

Also, I, to improve my speaking skills, get the most out of its recording-and-evaluating function. In the digital era, language learning methods need evolving. Casio e-dictionary featuring its profession, authority, fashion and convenience is undoubtedly an ideal auxiliary language learning aid. 注（给分的重要依据）：1. 第一段利用背景引出话题（要简洁）；2. 第二段简要说明“产品”，然后从“我”的角度相对具体地叙述“使用”；3. 第三段结合上文内容，阐述“评价”（要简洁并切题）；4. 内容充实；5. 语言质量，包括准确性和字、词、句的丰富性。 档次 规定任务 覆盖内容要点 语法结构、词汇 复杂结构、高级词汇 连接成分与结构 预期写作目的 第五档 （15—13分） 完全完成 覆盖所有 应用较多 尽力使用（语法结构或词汇有些许错误） 有效使用连接，全文结构紧凑 完全达到 第四档 （12—10分） 完成 覆盖所有，漏掉有一两个次要点 满足要求 语法结构或词汇方面基本准确 简单使用连接 全文结构紧凑 达到 第三档 （9—7分） 基本完成 覆盖所有，但漏掉一些内容 满足要求 语法结构或词汇方面的错误有一些，但不影响理解 简单使用连接 全文内容连贯 基本达到 第二档 （6—4分） 未恰当完成 漏掉一些主要内容，写了无关内容 语法单调，词汇有限 语法结构或词汇方面的错误有一些，影响对写作内容的理解 较少使用连接成分，内容缺少连贯 信息未能清楚地传达给读者 第一档 （1—3分） 未完成 明显遗漏主要内容，写了一些无关内容 语法单调，词汇有限 语法结构或词汇方面的错误较多，影响对写作内容的理解 缺乏连接成分，内容不连贯 信息未能传达给读者 第零档 未完成 与要点内容无关 内容太少 无 无 未能传达任何信息 续写（满分25分） “I have an idea!”Marcus said, taking the large tablecloth from his mother. Now instead of disappointment, Marcus felt a spark of inspiration. The stains, once a bother, now seemed like a canvas for creativity. He remembered the stories of his mother's makeshift costumes and decided to embrace the imperfection. After drying the tablecloth, he grabbed it and draped it over himself. His sister, quickly catching on, added some tinfoil to create the illusion of armor. With a bit of face paint to highlight the spots, Marcus transformed into an otherworldly being. Eager to check out his new look, he dashed to the mirror. As Marcus stood in front of the mirror, a broad smile spread across his face. His reflection was something out of a sci-fi fantasy, a character that was uniquely his own. His family gathered around, admiration in their eyes. His mother, who had once been a little sad about the old tablecloth, now beamed with pride at her son's ingenuity. Marcus realized that the best costumes didn't have to be store-bought or perfect. They could also be his own creation. “I’m a clumsy ghost. See! I’m covered in purple bruises. No one else will have this costume!” Marcus explained happily. Then he turned to his sister and announced,“Let’s go trick-or-treating!” 关注点：1. “万圣节”这一故事背景；2.
