It is a place for the students to introduce their favorite books to the class. This week it’s Ann’s Group’s turn to post their book introductions.Tim: I like the book The Wandering Earth. It first attracted my attention when I saw the movie based on the book during the Spring Festival. It is a science fiction about driving the earth away from the solar system. I really enjoy seeing what the world will be like when it comes to the end. I think it’s one of the most creative science fictions written by a Chinese writer.Ann: The Innocents Abroad is a travel book by the American author Mark Twain published in 1869. It describes a journey of a group of American travelers in 1867. It was the best-selling of Twain’s works during his lifetime, as well as one of the best-selling travel books of all time.Sara: My favorite book is Linnea in Monet’s Garden. It’s a story about a little girl visiting Monet’s art in museums. She also visits the artist’s home and gardens. What I like most is that the full-color photos of Monet’s famous paintings.Ben: Grand Canyon is an introduction to the natural history of the canyon. If you like geography, I’m sure you’ll like it. You can find lots of amazing photos in the book. It’s perfect for young travelers, campers, and observers of the natural world, especially for those planning a trip to the Southwest.11．The Wall Paper allows the students to ________.A．share the books they like B．learn about different studentsC．introduce their favorite movies D．show their reading experience12．If one likes travelling, which two of the books can be chosen?A．The Wandering Earth and Grand Canyon.B．The Wandering Earth and Linnea in Monet’s Garden.C．The Innocents Abroad and Grand Canyon.D．The Innocents Abroad and Linnea in Monet’s Garden.13．What do we know about the book The Wandering Earth from Tim?A．It was published during the Spring Festival.B．It describes the solar system.C．It is a book about making a movie.D．It is written by a Chinese writer.Para 1.Stonehenge is an ancient circle of stones in the south of England. It was built about 5,000 years ago. Every year, it attracts thousands of tourists to enjoy its beauty. They also wonder about how and why it was built.Para 2.There are about 80 stones and each is about five meters tall. The stones were 380 kilometers away from where they were made. The ancient people had only wooden tools. To move the stones they probably used tree trunks(树干) to roll them along. So it was a wonder to build Stonehenge. Scientists say it took millions of man-hours to move and raise the heavy stones. How did people move these huge pieces of stone from the place so far? No one knows the answer. One record said the great stones were carried to England by huge magical(有魔力的) aliens! But we don’t know.Para 3. Some scientists believe that Stonehenge was a temple. Some believe it was a place to bury dead people or perhaps it was used to study the stars and the sky at night. Others think it was even used to tell the time. Whatever the stones were used to do, they have always been the pride of British people.Para 4.In modern times Stonehenge has become a huge hit with tourists.14．Which paragraph tells about the use of Stonehenge?A．Paragraph 1.B．Paragraph 2.C．Paragraph 3.D．Paragraph 4. 15．Which of the following is NOT true according to the passage?A．Stonehenge attracts many people from all over the world every year.B．Scientists don’t exactly know what tools ancient people used to roll the stones.C．The stones have always been the pride of British people.D．British men carried heavy stones from over 380 kilometers away.16．What is the best title for the passage?A．Magical Stonehenge B．A Man-made Wonder in EnglandC．Visitors to Stonehenge D．Some Uses of Stonehenge Earthquakes happen without warning（前兆）. They can happen any time of a day, at any point during the year. But don’t worry because most earthquakes are so weak that they cannot be felt. Only a few big ones hurt people. However, it’s important to know what to do when an earthquake is happening.Do NOT go outside. You could get injured from falling glass or parts of buildings. Ifyou are outside, stay away from buildings and power lines（输电线）.Stay under a desk, table, or other strong furniture. Hold on to it. Or stay in a corner of the building. Cover your face and head with your arms and cover your mouth with a towel or clothing. Stay inside until shaking stops and it is safe to go outside.Keep away from windows, pictures or advertisements on the wall or the building, and anything else that could fall and hurt you. Most people get injured by falling things during an earthquake, not by the shaking itself.Also keep away from a fire. You could fall down and burn yourself on the fire.If you are driving when an earthquake happens, stop the car if it’s safe. Stay inside your car until the earthquake stops, and don’t drive near bridges. Try not to stop by power lines or trees. These could fall and hurt you.17．Most earthquakes are so ________ that they can’t hurt people.A．strong B．weak C．dangerous D．heavy 18．From the passage, when an earthquake is happening, we should ________.A．stay under a big buildingB．stay under a strong furnitureC．stand by windowsD．drive near a big bridge19．How many ways are mentioned in the paragraph?A．Four B．Six C．Five D．Seven 20．This passage tells us ________.A．how dangerous the earthquake isB．how to be safe in an earthquakeC．we shouldn’t be afraid of the earthquakeD．how the earthquake comes into being21．The best title for this passage should be “ ________”.A．How Earthquakes HappenB．How to Drive a CarC．What We Should Do in EarthquakesD．Why Earthquakes HappenThe Qinghai-Tibet plateau is a mountainous area in western China that sits about 4,000 meters above sea level. This beautiful natural environment is made up of grassy lands, lakes and glaciers (冰川). Very few people live in the area, but it is home to many animals, including the endangered Tibetan antelope (藏羚羊).Thousands of Tibetan antelopes once lived in this area, but their populations dropped in the 1980s and 1990s. This was in large part the result of poaching (偷猎). Poachers often killed Tibetan antelopes for their soft and highly prized wool.Over recent decades, however, much has been done to protect these animals. The government has made it much more difficult for poachers to operate in the area by introducing strict laws. And in the spring, when thousands of Tibetan antelopes make a long journey to Hoh Xil, government workers follow the antelopes, making sure that they are protected from poachers and from other wild animals.The government has also taken steps to slow down tourism in the area, since tourists often disturb the natural habits of animals.All of this work has had good results.

We went on the Head Knocker, the Crazy Coaster, and the Monster Masher before I started feeling really sick.A moment later I was really upset and my face was red, so my friends suggested we go on a water ride so I could cool down. I thought it was a good idea, but when we rode it, I forgot to take my glasses off. They fell off and into the water. I watched helplessly as they sank to the bottom while we kept rushing forward. I had to go through the rest of the day nearly blind.I have decided that I will never go to Magic Land again, even though someone offers me a million dollars!1. decided2. worst3. first4. stop5. before6. my7. but8. off9. the 10. never八、单词拼写71.

Unit3BuyingandSelling美国的跳蚤市场doc初中英语
Unit3BuyingandSelling美国的跳蚤市场doc初中英语美国的跳蚤市场。
在美国各地，不论是繁华的大都市依旧偏远的小镇，都有许多跳蚤市场，供家庭不富裕的人购买一些价廉物美的生活用品。
跳蚤市场的规模大小不一，大多是临时租赁的运动场馆、社区活动中心、市政广场等规模较大定期开放的固定场所，也有专门买地开创的市场。
跳蚤市场的开放时刻以周末居多。
同时多数市场在下午三点以后就散去。
相邻都市的市场常常将开放时刻错开，以便摊贩们能够往来走动，如此也就产生了一群以此为职业的摊主。
因此也有相当部分的摊主有自己的工作，只是在周末休息时，才去那些规模较大的市场赶场。
跳蚤市场的业主们，为吸引更多的商贩和顾客，常常打出各类广告，也积极改善条件。
跳蚤市场里的物资可谓花样繁多，多是人们日常生活用品。
你在那个地点能够只花2美元买件T恤，花10美元买条牛仔裤，还有些什么小物件，小摆设等让你看得眼花缭乱，但有一个共同点，确实是价格廉价。
那个地点的新商品，由于不需要支付昂贵的租金和雇员的人工费，常常要比商场里廉价20%-50%。
而在二手商品专区，你甚至能够以更低廉的价格买到你需要的东西。
跳蚤市场里有大量的中国产品，也就不乏大量的中国人摊主。
在那个地点中国人的吃苦耐劳精神更是表达得完全。
有一个卖眼镜的温州人，往常开中餐馆，最初是休息时，来市场卖眼镜，后来干脆将妻子亲小孩一同带来，每天用他的旧〝道奇〞拖着一个拖箱，穿梭于各个跳蚤市场之间，其间就睡在车内。
这些产自温州的眼镜，尽管只卖5美元左右，但也有300%以上的利润，假如天气好，每周收入在5000美元以上，比他往常开餐馆赚的还多。
目前在专门多地点的跳蚤市场，中国人已垄断了大部分商品的销售。

买和卖作文英语
Buying and Selling: A Dual Perspective onCommerceThe world of commerce revolves around two fundamental activities: buying and selling. These actions, although seemingly straightforward, encompass a vast array of complexities and nuances that shape our economic landscape. From the bustling bazaars of the ancient world to thevirtual marketplaces of the digital age, the dynamics of buying and selling have evolved significantly yet retain their fundamental essence.Buying, at its core, is an act of selection and acquisition. It involves the careful consideration of needs, wants, and budget, followed by the negotiation and finalization of a transaction. The buyer enters the marketplace with a purpose, searching for goods or services that will fulfill a specific need or desire. This processis often influenced by personal preferences, cultural norms, and market trends, all of which shape the buyer's decision-making process.On the other hand, selling is an art of persuasion and value creation. It requires an understanding of the buyer'spsychology, the ability to communicate the benefits of a product or service, and the negotiation skills to reach a mutually beneficial agreement. The seller must not only present their offerings in a favorable light but also ensure that they meet the buyer's expectations in terms of quality, price, and overall value.The interaction between buyers and sellers creates a dynamic marketplace where supply and demand constantly reshape the economic landscape. As buyers' needs and preferences evolve, sellers must adapt their offerings to stay competitive. Conversely, sellers can also influence buyers' preferences through marketing and advertising, shaping demand and creating new trends.In today's globalized world, the reach and scope of buying and selling have expanded exponentially. Online platforms have disrupted traditional retail models, allowing buyers and sellers to connect directly across borders and time zones. This has opened up newopportunities for both parties but also presents new challenges, such as managing cultural differences, currency fluctuations, and shipping logistics.Despite these changes, the fundamental principles of buying and selling remain the same. Buyers still seek value for their money, while sellers strive to create and communicate that value. The balance between these twoforces drives the engine of commerce, powering the global economy and shaping our lives.In conclusion, buying and selling are not just economic transactions; they are also cultural and social phenomena that reflect our values, preferences, and aspirations. Aswe navigate the complexities of the modern marketplace, itis essential to remember that buying and selling are notjust about profit and loss but also about creating connections and value that enrich our lives.**买卖：商业的双重视角**商业世界的核心在于两大活动：买与卖。
