广东省东莞市高一政治上学期期末考试试题(含解析)

广东省东莞市2018-2019学年高一上学期期末考试政治试题一、选择题：本题共24小题，每小题2分，共48分。

每小题给出的四个选项中，只有一项是符合题目要求的。

1.近年来，知识经济呈现井喷式发展，为知识“买单”已成为风潮。

《中国新媒体发展报告（2018）》显示，到2017年底，知识付费用户达到1.88亿人。

这里的“知识”A. 不是商品，因为它不是劳动产品B. 是商品，因为它既有使用价值又有价值C. 是商品，因为它能满足人的精神需求D. 不是商品，因为它是无形的产品【答案】B【解析】【详解】材料中的“知识”是劳动产品，最终是为了通过交换获得价值，商品是用于交换的劳动产品，故材料中的知识属于商品，由此可以判断AD两个选项说法错误。

价值是商品的本质属性，材料中的知识在知识经济时代显现出巨大的价值，并且通过交换获得了价值，B选项说法正确。

满足人们的精神需求不是商品的本质属性，故不是判断一事物是否为商品的标志，C选项说法错误，本题选择B选项。

【点睛】判断某种物品是不是商品的方法。

①定义法：看物品是否同时具备两个条件：一，是不是劳动产品；二，是否用于交换。

二者缺一不可。

②属性法。

看物品是否同时具备商品的两个基本属性，即使用价值和价值。

只具有使用价值而无价值的物品不是商品。

③领域法。

虽为劳动产品，关键还要看是否已经离开流通领域。

如：离开流通领域的礼品，进入消费品领域就不再是商品。

2.2017年11月6日人民币对美元中间价为6.6247元，2018年11月6日人民币兑美元中间价为6.9075元。

若不考虑其他因素，下列说法正确的是A. 美元贬值，美国进口中国商品的价格上涨B. 美元升值，中国人赴美旅游、留学成本增加C. 人民币升值，中国企业在美国投资成本下降D. 人民币贬值，不利于中国商品和服务的出口【答案】B【解析】【详解】从材料中可以得知，2017年到2018年，人民币兑美元中间价增多了，说明了人民币贬值，美元升值，由此可以判断AC两个选项说法错误。

2019届广东省汕头市高三毕业班教学质量监测理综物理试题(解析版)

汕头市2018-2019学年度普通高中毕业班教学质量监测试题理科综合(物理)二、选择题：本题共8小题．每小题6分。

在每小题给出的四个选项中，第14～17题只有一项符合题目要求，第18～21题有多项符合题目要求。

全部选对的得6分，选对但不全的得3分．有选错的得0分。

1.在中国，每年由于交通造成死亡的事故中50%以上都与酒后驾车有关，酒后驾车的危害触目惊心。

驾驶员从视觉感知前方危险，到汽车开始制动的时间称为反应时间，酒后驾驶将明显增加反应时间。

对比某驾驶员正常驾驶和酒后驾驶过程，记录感知前方危险后汽车运动v-t图线如图甲、乙所示。

则A. 图乙对应于正常驾车B. 全过程酒后驾车的时间比较短C. 全过程酒后驾车的位移比较小D. 全过程酒后驾车的平均速度比较大【答案】D【解析】【分析】汽车刹车做匀变速直线运动，注意驾驶员在反应时间里没有操作车，故汽车仍做匀速直线运动，根据图象得出初速度、反应时间等，根据匀变速直线运动规律求解【详解】A、驾驶员在反应时间里没有操作车，汽车仍做匀速直线运动，酒后驾驶将明显增加反应时间，图乙对应于酒后驾驶，故A错误；BC、设驾驶员饮酒前、后的反应时间分别为t1、t2，由图线可得t1=0.5s，t2=1.5s；汽车初速度v0=30m/s，正常驾驶时的减速时间为t3=4.0s，由图线可得正常驾驶时的感知制动距离为：，同理，可求出酒后驾驶时的感知制动距离为：，故B、C错误；D、根据可得正常驾驶时的平均速度，同理，可求出酒后驾驶时的平均速度，故D正确；故选D。

【点睛】关键是知道运动过程，驶员在反应时间里没有操作车，汽车仍做匀速直线运动。

2.如图所示，放置在水平地面上的箱子内，带电小球a、b用绝缘细线分别系于箱子的上、下两边，均处于静止状态，下列说法正确的是A. 两球一定带异种电荷B. 若增大b球带电量，连接b的绳子拉力可能变小C. 若增大b球带电量，连接a的绳子拉力可能不变D. 若增大b球带电量，箱子对地面的压力一定增大【答案】A【解析】【分析】根据b处于静止状态，一定受到竖直向上的库仑引力和可能受到绝缘细线的拉力，由此分析；【详解】ABC、以b为研究对象，因处于静止状态，则一定受到重力和竖直向上的库仑引力，可能受到绝缘细线的拉力，所以两球一定带异种电荷；若增大b球带电量，b受到竖直向上的库仑力增大，连接a的绳子拉力增大，连接b的绳子拉力也增大，故A正确，B、C、错误；D、以整体为研究对象，因均处于静止状态，受到重力和竖直向上的支持力作用，二力平衡，若增大b球带电量，还是受到重力和竖直向上的支持力作用，二力平衡，根据牛顿第三定律可知箱子对地面的压力不变，故D错误；故选A。

2019年汕头市学年质量监测高一语文试题参考答案

2019年汕头市学年质量监测高一语文试题参考答案1.【参考答案】B【解析】B项，“是为了亲自体验和感受小说中“王满银”的活法，从而感到生活的自由自在”表述错误，南下广州城是为塑造“王满银”这一形象积累更多的生活素材，从而体现路遥的创作源于生活，取材于生活。

2.【参考答案】B【解析】A项，“从不虚构、编造”表述太绝对化。

C项，表述不全面，路遥的凌乱、不顾及个人形象更多的是他把心思放在了创作上。

D项，从对刘春生、申晓等人的描述中可得知他们是清楚路遥的病情的，从路遥忙于与朋友聊天、整理文稿的描述中可得知路遥也是知道自己的病情的，只是在抓住生命的最后一刻在努力的创作。

3.【参考答案】这句话的意思是自古以来能够成就伟大功绩的人，不仅有超凡出众的才能，还要有坚忍不拔的意志。

路遥就是一位有着坚忍不拔的意志的作家：①为了创作，路遥毅然放弃自己爱好，深入到生活中切身体验，为写作积累丰富的生活素材，矢志不渝。

②即使《平凡的世界》获得了我国最高的文学奖，路遥也不骄傲自满，而是作自我总结，继续进入创作积累阶段，始终坚持文学创作的道路。

③尽管疾病缠身，精神状态欠佳，路遥始终进行文学创作，整理文集稿件，一直到身体走向崩溃的边缘。

④尽管文坛有着“唯洋是举”的风气，路遥始终坚持着自己的创作原则，秉持着严肃认真的现实主义创作态度，意志坚定。

【评分标准】句子理解2分，结合文本内容4分，对文本内容的分析共有4点，考生只要任意答对2点即给满分。

考生如有其它答案，也可酌情给分。

4. 【参考答案】B【解析】B项“我是说他会不会还描了地图什么的?他脑瓜比谁都活，除了偷我烟酒，准还描了地图!”“真这样，可就更毁了。

”的对话只是大家的猜测，大家以为牛犇外逃了，所以才会设想种种可能，但文中并没有迹象表明大家对牛犇早有怀疑。

属于“无中生有”类型。

5.【参考答案】①牛犇聪明机智，饱读诗书。

从一出场就显现出文人的气质，对着风雪朗诵《雪国》。

②牛犇勇敢细心，在望架上仔细观察对方的情况后孤身一人偷偷跑去换奶。

AWild Times In The Lone Star StateWhether you are enjoying the atmosphere in old-time towns, hiking into untouched wilderness or preparing for horseback adventures, the plains, grasslands and valleys of Texas make for an astonishing journey. This is a land rich in natural wonders—read on to discover how you could absorb yourself in a little authentic western culture.Hike A Natural WonderLocated in the Texas, Palo Duro is the second largest canyon(峡谷) in North America, dropping more than 240 metres. The highlight of along walk in this rough but beautiful region is to climb to the Lighthouse, a sandstone rock structure. From here, you will be amazed at the view across miles of dramatic Texas wilderness.Enjoy An Enchanted DuskShaped like a large, pink loaf of bread, the Enchanted Rock stands 130m highat the top. Hike up to its summit before sunset to take in the view across the uneven land below-and listen carefully: as night falls, you might just hear the rock start to make a screeching noise, just as the old legends insist it does at dusk.Meet The Real CowboysFort Worth, as Texans will tell you, is known as Cowtown. Every morning and afternoon, a herd of longhorns moves along Exchange Avenue in the world’s only daily cattle drive. The cows are heading to the stockyards. This energetic district is full of exciting bars and restaurants set among grand early 20th-century buildings.Explore The DepthsPreviously only accessible to experienced explorers, a section of the Natural Bridge Caverns—a huge cave system near San Antonio—has now been opened to all comers. It includes a new viewing area overlooking a passage called the Box Canyon, which provides a natural theatre for a sound and light show.21. What is Texas abundant in?A. Natural attractions.B. Old legends.C. Grand buildings.D. Ancient towns.22. Which place is recommended to enjoy the sunset scenery?A. Palo Duro.B. The Enchanted Rock.C. Fort Worth.D. The Natural Bridge Caverns.23.

Tourists can overlook the Texas wilderness in the Natural Bridge Caverns.D. Climbing to the Lighthouse is the most attractive part of the hike in Palo Duro.BWhen I was in senior high school, I was scared of writing application letters. One of my biggest fears was the fear of rejection. Keeping myself in a safe space and doing things that I know I can perform well was my favorite pastime. But I knew I had to make a change, so I tried to apply for the college myself.When I received the first reply letter, I was taking a class then. My heart was beating wildly while I waited for the school internet to connect faster. When I saw the letter starting with “Thank you for your application. After a careful review...”, I felt my face growing hotter. Although it was a college I was not thinking of going to even if I did get in, I was heart-broken.This fear is applicable anywhere else: the fear of having your projects or ideas rejected or even the fear of being rejected from your friend group, to name but a few. I cannot tell you how many times I passed up the opportunity because I always thought there were better applicants out there, and for this reason, I missed out on so many opportunities to grow.Even nowadays, when I get a rejection letter from a scholarship application, I have the same immediate reaction, no matter how many rejections I’ve gone through. But the aftermath(创伤) does get easier Every time I am rejected, I am able to bounce back and hand in another application more quickly. Along the journey of rejections, I realize that I am not incompetent, but that everyone else maybe more capable. And that is okay.This fear will never truly go away. I’m still terrified to write and publish my articles. But it is thrilling to know that I write what I want to say, explore my mind and learn more about myself. Uncertainty is scary, but without experiencing the scariness, we would never grow, would we?24. What can we know about the author’s applying for the college?A. He knew he could perform it well.B.

Seize the opportunity to grow.CFor 32 years, Brenda Richardson has provided nutrition(营养) services to a diverse group of people aged 50 and older. Her journey began in college when she took a nutrition course that lit up her passion to become a registered nutritionist.After earning an undergraduate degree in dietetics(膳食营养学) and institution administration, Richardson was selected to practice at Walter Reed Army Medical Center in Washington, ter, she worked at several military emergency facilities and then became the hospital chief of clinical dietetics. She also left active duty to work as a food buyer and nutrition educator for schools. “I am excited to see the real impact that food, nutrition and dining can have on the prevention and management of malnutrition and the quality of life for each kid.” she recalled.In 1987, Richardson was offered a role serving a different population in long-term care. She was not only a consultant for independent living, assisted living and nursing facilities, but a so worked with food producers and distributors to develop dietary supplement products for seniors. Additionally, she volunteered with some organizations, where she provided education and training for their members to serve the elderly. “While I enjoy working in emergency care and schools, I prefer working with my colleagues.to prove the value of nutrition for healthy aging,” she said. “It is so rewarding to see improvements in person-centered care, the prevention and-management of malnutrition and other diseases, and the positive impact nutrition on individuals’ daily lives.”In 2019, after being nominated by the HealthCare Community Dietetics Practice Group and Indiana Academy of Nutrition, Richardson received the Lenna Frances Cooper Memorial Lecture Award. “This is a great honor that represents Cooper’s heritage and leadership in the field of nutrition and dietetics,” she said. “Her heritage has enabled me to improve my life through evidence-based nutrition. I am honored and humble.”28. What motivated Richardson to be a registered dietitian at first?A. Her duty for schools.B. Her journey to a college.C. Her service for seniors.D. Her attendance in a nutrition course.29. What is Richardson’s special contribution as a dietitian?A. She served as a nutrition consultant for schools.B. She became director of clinical nutrition at the hospital.C. She volunteered with her fellows to prevent diseases for each kid.D.

Distributed.31. Where is this article probably taken from?A. A health magazine.B. A senior service website.C. A nutrition cookbook.D. An education newspaper.DIf you’ve ever cooked a complex meal with someone, you know the level of cooperation required. American researchers recently showed that in a virtual kitchen, artificial intelligence (AI) learned how to cooperate with ahuman just by watching humans work together.There are some ways researchers have already trained AI to work with people. Many approaches involve reinforcement learning, where an AI interacts with an environment online-which can include other AIs or humans—and is rewarded for making decisions that lead to desired outcomes. Google Deep Mind’s program Alpha Go, for example, learned the board game Go using reinforcement learning.But starting training an AI from zero to interact with people through complete trial and error can waste a lot of time and can be risky. Another choice is to train one AI to model human behavior, and then use that as a tireless human replacement for another AI to learn to interact with. Researchers have used this method in a simple game. But repeating human behavior in more complex settings can be difficult.Thus in the study, researchers used offline reinforcement learning—a method for developing strategies by analyzing recorded behavior rather than through real-time interaction. Previously, offline reinforcement learning had been used mostly to help virtual robots move or to help AIs solve mazes (迷宫), but here it was applied to the tricky problem of working with humans. Instead of learning by interacting with people, this A I learned by watching human interactions.“The research work introduces away for AI to learn to team up with humans, without even practicing with us. It could help improve human-AI interactions.” says Nikolaidis, director of a lab.In the future, humans will increasingly work with AI, both online and in the physical world. Sometimes we’ll want an AI to silently guide our choices and strategies, like a good teammate who knows our weaknesses. “It solves an important problem how AI can learn to work with people,” says Nikolaidis.32. What is the function of reinforcement learning in the passage?A. It’s how AI learned to work with peopleB. It’s how researchers helped AI learn cooking.C. It’s how Google Deep Mind developed AlphaGo.D. It’s how AI got rewards for making correct choices.33. What is the advantage of offline reinforcement learning?A. It relies on real-time interaction.B. It helps AI learn by interacting with people.C. It takes less time and has less danger.D. It is realized through mistakes and corrections.34. What is AI expected to do in the future?A. To cook a complex meal on its own.B. To point out our weaknesses directly.C. To offer voiceless guidance sometimes.D. To solve difficult problems for humans.35. What is the text mainly about?A. AI learns cooperation by practising.B.AI learns cooking from humans.C. AI learns cooking without humans’ help.D.AI learns teamwork by watching humans.第二节（共5小题；每小题2.5分，满分12.5分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

After silencing it, I remained in bed. My motivation to push ahead with my PhD was disappearing, which made it hard to face each new day. Continuing would risk a total breakdown. With anxiety, I decided to cease my PhD temporarily and take a 9-month position at a health care charity. Back when I looked for PhD positions, I was unclear what I wanted to study. For me, the degree mostly served as a means to an end, securing more interesting and higher-paid positions in the private sector than my master's degree would unlock. So I wasn't picky and reasoned a variety of projects that would provide the training and degree I wanted.In hindsight (事后想来) , I should have been more selective. I ended up working on a project I was technically capable of completing but over time felt full of disappointment. The purely academic research was intellectually interesting, yet I struggled to see how it would make an impact on the wider real world.Some unexpected things amplified my trouble. I started my program in 2020, when meetings were virtual and in-person contact was actively discouraged, so I had few opportunities to form personal connections with co-workers. Research became my only focus, and when my interest in that faded, my project feltdepressing.After only one month at the charity, it became clear that I'd made the right decision. My mental health improved and I found it easier to come into work. Things I did could matter and energize me after all — if I chose wisely. That was exactly what I needed and desired. After that realization, I decided I wanted to return to my PhD program and make changes. I told my teacher I wasn't interested in the current research. To my relief, he was supportive, and we redesigned the project to better fit me. I will return to my program next month, optimistic that this time will be different. But if it doesn't go as I hope, my charity experience has given me direction and confidence that I'll live a satisfying life, with or without a PhD.24. What did the author view the PhD degree as at firstA. A struggle for new days.B. A breakthrough in his study.C. A way of getting a better job.D. A chance to build connections.25. Why did the author become disappointed at his projectA. It was of slight practical use.B. It failed to meet his social need.C. It showed an unpromising future.D. It had a high degree of difficulty.26. What does the underlined word "amplified" in paragraph 3 meanA. Reflected.B. Caused.C. Solved.D. Increased.27. How did the charity work affect the authorA. It inspired him to face challenges.B. It helped him find a purpose in life.C. It fueled his enthusiasm for his program.D. It enabled him to make the right decision.CIn May 2012, Australia’s Macquarie Dictionary and the McCann Advertising Agency gathered a group of language experts to name a phenomenon common in the age of the smartphone . They called the phenomenon “phubbing”, and defined it as “the act of snubbing (无视) someone in a social setting by looking at your phone instead of paying attention.” It’s not the usual way words begin to exist.A month later, the first example of phubbing in a major newspaper appeared in a letter to the editor of The Age, published in Melbourne. Since then, the word has appeared in various media the world over. Phubbing has yet to be fully adopted in the U. S. , but we have collected some evidence of it in use.On 29 September 2015, James A. Roberts wrote in the Huffinington Post, “In the present case, phubbing is a combination of the words phone and snubbing. To be phubbed is to be snubbed by someone using their cell phone while in your company. The ‘phubb’ could bean interruption of your conversation with someone when he or she uses their cell phone or is distracted by it (steal glances when they think you’re not lo oking) instead of paying attention to you . Maybe worse, you’ve been phubbed if someone used their cell phone instead of communicating with you while staying close to you. Oh , the shame.”The meaning and various forms of the word have yet to settle out . Is it phubbing if you’re staring at your tablet instead of your phone Is the singular noun (and the base form of the verb) spelled phubb, as in the example above, or phub, as in some other sources These are the sorts of questions we’ll need answers to before we’re ready to consider phubbing and its relations for entry. In the meanwhile, you can of course use phubbing if you feel the need . It seems we all do these days.28. What does Paragraph 1 mainly talk about phubbingA. Its usage.B. Its birth.C. Its influenceD. Its definition.29. What may phubbing probably lead to according to James A. RobertsA. Obvious embarrassment in life.B. Heavy reliance on cellphones.C. Complete ignorance by your friends.D. Permanent breakup of relationship.30. What can we learn from the last paragraph about the wordphubbA It arouses heated arguments. B. It proves to be settled.C. It’s not included in a dictionary.D. It’s not difficult to understand.31. Which of the following is a suitable title for the textA. Where Phubbing Leads UsB. Why Phubbing Ruins Our LifeC. What Makes Phubbing Commonly SeenD. How Phone Snubbing Becomes PhubbingDWhat makes people so special Tool use, self-consciousness, language, and culture are high on the list , but in fact all of these characteristics can be found elsewhere in the animal kingdom. Humans and apes are close relatives, so it is perhaps not surprising that chimpanzees use tools or that gorillas have a sense of fair play, even rejecting carrots (which they normally accept) when they see their neighbors getting grapes. But the qualities that we often think of as exclusively human exist not just on land, but in the ocean as well.Among the invertebrates (无脊椎动物), octopuses (八爪鱼) are known for their intelligence, even exhibiting evidence of playfulness , tool use , and personality . But these skilled predators live alone and consequently lack culture . Dolphins , on the otherhand , are large-brained , long-living , social-group-based predators , and it is here that we find the greatest similarity to human-like culture and awareness.Culture depends on the ability of animals to pass on things they have learned to others . Many animals have culture in this sense , but what sets dolphins apart is what they pass on . Some bottlenose dolphins hold sponges in their mouths that they use as tools to sweep for fish hiding on the ocean floor . This ability is handed down through generations (especially in females) , with some families —grandmother , mother, and daughter —all feeding in this highly specialized way.Another characteristic that dolphins share with humans is their ability to recognize themselves in a mirror. When facing a mirror, most animals behave as though they are interacting with another individual. Even in humans, the ability to recognize that the image in a mirror is oneself does not occur before the age of 18 months. Dolphins not only recognize themselves, but if a black mark is put on the body of a dolphin, it will spend extra time at the mirror to look at the mark.The example of gorillas rejecting carrots shows they _____.A. are not easy to foolB. prefer fruit to vegetablesC. have a special taste for foodD. have an awareness of equality33. What do octopuses lack compared with dolphinsA. Social interaction.B. Intelligence.C. Tool using ability.D. Fun-loving spirits.34. What makes dolphin culture specialA. They tend to hunt in groups.B. Their hunting skills are passed down.C. Their learning environment is favourable.D. Their families are typically female-controlled.35. What can be inferred from the last paragraphA. Dolphins enjoy looking at their own reflection in the mirror.B. Dolphins are as intelligent as a typical 18-month-old human baby.C. Dolphins are generally regarded as the most advanced non-human species.D. Dolphins’ ability to recognize their own reflection is a higher-order mental skill.第二节（共 5 小题，每小题 2.5 分，满分12.5 分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

广东省汕头市潮阳启声学校2023-2024学年高一下学期开学考试英语试题

广东省汕头市潮阳启声学校2023-2024学年高一下学期开学考试英语试题一、阅读理解Most Beautiful National Parks in PolandPoland’s national parks are a hidden treasure for nature lovers. Take a walk on the wild side with us and experience four of the best open air spaces.Bieszczady National ParkThis park is in the remote south-eastern corner of the country bordering with Ukraine and Slovakia. It’s a great choice for people looking for a quiet and lonely trip. Facilities are also quite limited. Don’t miss the Solina Dam and other artificial lakes.Karkonosze National ParkOver in the south-west of Poland by the frontier with the Czech Republic, this park is particularly interesting for its strangely shaped rocks and flat bare mountain tops. Near the border of the park is the highest waterfall in the Sudety region of Poland, the Kamienczyk Waterfall, which is 27 meters high.Wolin National ParkCovering a large part of the Wolin Island on the western side of the Polish coast, this park’s best parts include an amazing 15 km long stretch of steep sea cliffs (悬崖), lakes and rivers surrounded by pine trees, many bird species and a small bison (野牛) reserve.Pieniny National Park This park is on the border of Poland and Pieniny—one of the Pieniny’s most beautiful mountain ranges. By far the most popular activity is taking a raft ( 筏)down the winding Dunajec River, but there is a lot more to discover.1．Which park best suits people who want to explore the Solina Dam?A．Bieszczady National Park.B．Karkonosze National Park.C．Wolin National Park.D．Pieniny National Park.2．What can people do in the Pieniny National Park?A．Appreciate sea cliffs.B．See some small bison.C．Appreciate the highest waterfall.D．Float down the Dunajec River on a raft. 3．Where can the text be found?A．In an education brochure.B．In an art magazine.C．In a science magazine.D．In a guidebook.My first visit to London was one and a half years ago. It was a wonderful trip. I stayed in the city for three weeks, and I had many impressions. I visited all the famous places. I'd like to tell you about some of the places I visited in this beautiful city.First, I went to the Tower of London, and I want to say that it is a very interesting historical place.I found out that a long time ago, it was a prison. Later it became a castle for the royal(皇家的) family. Or maybe it is the reverse; I'm not sure, but later they left this place and lived in Buckingham Palace and Kensington Palace.I also enjoyed visiting the House of Parliament and Westminster Abbey, two very popular places for tourists. They are very old and beautiful. The Abbey is built in a kind of Gothic style; it is fantastic.In London, you can also enjoy nature. There are many parks such as Hyde Park, Green Park, and Holland Park. These parks are wonderful green, quiet places where you can relax and escape the noise of the city.Trafalgar Square is a popular place for students and other young people. You will find lots of pigeons（鸽子）there. If you have time, you can feed them and they will be very happy. You can buy special food for them, but be careful! Tons of birds are going to surround you if you feed them.Another very special place in London that I like is St. Paul's Cathedral which was designed by Sir Christopher Wren. I also was impressed with the museums in London. They're very popular. I found them interesting because you can learn about the history of England.I had a wonderful time in London. I really liked it because it is a city that is rich in history. 4．The writer writes this passage to__________.A．recall (回忆）his/her first travel to LondonB．tell us he/she has visited many places.C．introduce a famous city to the readers.D．show the readers around London5．In order to avoid the noise of the city, you would like to travel to ___.A．Buckingham Palace B．Holland parkC．The Tower of London D．Westminster Abbey6．What is attractive to you most in Trafalgar Square?A．Meeting many young peopleB．Catching a lot of birdsC．Having a delicious mealD．Feeding the pigeons7．During traveling in London, the writer was _______.A．worried B．surprised C．pleased D．tiredThe old Chinese saying “as happy as spending the New Year” might be outdated now in the busy modern world. The Spring Festival is regarded as the most important festival for Chinese people and an occasion for all family members to get together, like Christmas in the West. But many traditional customs accompanying the Spring Festival, however, have weakened in practice.Setting off fireworks was once the most typical custom of the Spring Festival. People thought the sputtering (爆裂) sound could help drive away evil spirits. However, the activity has been completely or partially forbidden in big cities for years as the government has taken safety, noise and pollution factors into consideration.“In recent years, some cities have begun to allow people to light fireworks during limited hours at the Spring Festival, surrendering to public demand. Respecting folk traditions is a gesture of respect toward public opinion.” said Zhou Xing, a folklore (民俗) researcher.“As people gain more income and it becomes easier to buy daily goods, the New Year holiday is just like any other. After long workdays, many people use the New Year holiday to take a rest, rather than visiting friends and neighbors. The process of making and enjoying the family dinner on Spring Festival Eve is the most important thing. However, many families would like to eat out to save time and energy,” said Li Shunzhi, a resident of Harbin, Heilongjiang.“I enjoy the holidays very much in the countryside. My family has been preparing for the Spring Festival more than two weeks before the holiday, cleaning the house, buying holiday goods and decorating the house with paper cuttings. On New Year’s Eve, the whole family stays up to see the New Year in, and in the days to follow, a series of activities such as lion dancing, dragon lantern dancing, lantern festivals and temple fairs will be held. Without the ancient traditions, the holiday is nothing to us,” said Zhang Hui, from Hebei.8．Which of the following is WRONG according to the passage?A．Setting off fireworks has been forbidden in some big cities for years.B．Nowadays, people can light fireworks in some cities at the Spring Festival.C．People believe that the sound of fireworks can drive away evil spirits.D．In the past, setting off fireworks couldn’t be seen almost anywhere.9．What does the underlined phrase “surrendering to” in the third paragraph probably mean?A．changing B．discovering C．satisfying D．leading 10．What Li Shunzhi said means ______.A．what people do during the festival now is different from the pastB．people would like to have the family dinner on Spring Festival EveC．people prefer to visit friends and neighbors rather than take a restD．the New Year holiday is just like any other day11．What does the whole passage show?A．The Spring Festival is as lively as before.B．The Spring Festival is outdated now.C．The Spring Festival is losing its qualities.D．The Spring Festival is nothing to Chinese.While computers are incredibly useful tools, they can also be addictive. Many kids have the problem of spending too much time on the computer. Help your child overcome their own computer addiction by using the following methods.12 If you are not at home, you can change the password (密码) daily and send it to your child remotely once you’re ready to give them access (机会).13 Limit your child to using the computer for a maximum of two hours per day if they are over two years old. Children under two should not have access to any screen time.Talk with your child about their excessive computer use. Find out if there are any specific reasons why they spend so much time on the computer. 14 If your child is facing problems that are causing a desire to escape, address those with them through discussions, providing advice, or getting them help when necessary.Be a good role model. 15 Instead, be present when you are with them and work onspending more time together.Encourage them to join clubs or organizations. Find out from them what clubs or organizations are offered at their school. 16A．Set a time limit on computer use.B．Encourage your child to read books.C．Set a password for the computer that only you know.D．Don’t spend a lot of time using the computer around your child.E．Sometimes, the computer can function as an escape from reality.F．Some children may stay up late into the night in order to use the computer.G．This will provide them with another way of meeting others and developing new hobbies and interests.二、完形填空”Mommy, I got something for you!” Cody ran through the door after school. His face wore the biggest smile ever. He waved something above his head. “It’s a pen. But not just any pen. It’s a lucky pen!” He handed me the pen 17 , waiting for my reaction (反应).I looked at the pen in my hand. There was nothing 18 about it. It looked just like any other ballpoint pen.

Now he stood in front of me, watching me examine the pen. “You don’t have to be afraid now,” he said. “This pen will make your 23 great and everyone will love you.”Tears filled my eyes. Refusal (拒绝) and failure didn’t seem like such a big problem any more. Even if I 24 sold the first book, I had everything I could ever need. I knew that pen would bring me luck, though. And I felt 25 already, just by having Cody in my life, especially when I heard what he did to get it.In the lunchroom, Cody heard an older boy talking about having a lucky 26 .
