Period One Topic Talk 1 The Internet: a world without frontiers (边界) The Internet has the power to connect people across the world to a single shared community. Billions of people in different parts of the world have joined it already, and obviously many more will follow. Even in the countryside, the Internet enables people to reach beyond their villages and get in touch 主题素养积累 2 with the outside world. We can achieve almost anything online—with access to the Internet come some truly life- changing advantages. One of the greatest advantages of the Internet lies in the quick and easy access to a huge amount of information. To a certain extent, the world's knowledge is all at our fingertips. With the click of a mouse or the touch of a button, it is possible to find out almost anything we care to know. 主题素养积累 The Internet has also made our lives unbelievably convenient, with all sorts of goods and services provided by electronic commerce, more commonly known as e-commerce. You can have food delivered to you using food delivery apps and sites. Why wait hopelessly for a taxi in the cold rain? It is now simple and fast to order one with a taxi app. Sit back and relax indoors for a few warm minutes until the driver arrives. Above all else, the Internet helps us establish and maintain social ties. With all sorts of communication software, physical 主题素养积累 distance no longer gets in the way. No matter where we are, we are able to keep in contact with loved ones, find long- lost friends and discover whole new communities who share our hobbies. While the Internet brings many valuable advantages, being connected has its problems. As with any great invention, we must be aware of these problems and be careful to use the Internet properly and responsibly. Only in this way can the Internet be a place of discovery, wonder and inspiration for everyone. It is truly a world without frontiers. 主题素养积累 【主题词句背诵】 1.get in touch with和……取得联系 2.advantage n.好处 3.lie in 在于,存在于 4.to a certain extent 在一定程度上 5.click n.点击 6.get in the way 妨碍 主题素养积累 6 7.The Internet has also made our lives unbelievably convenient, with all sorts of goods and services provided by electronic commerce, more commonly known as e-commerce. 互联网通过电子商务——也就是通常所说的电商——提供各种各样 的商品和服务,使我们的生活变得异常便利。 8.No matter where we are, we are able to keep in contact with loved ones, find long-lost friends and discover whole new communities who share our hobbies. 不管身在何处,我们都能与所爱之人保持联系,找到久违的朋友,发现兴 趣相投的新群体。 主题素养积累 7 9.Only in this way can the Internet be a place of discovery, wonder and inspiration for everyone. 唯有如此,互联网才能成为每个人的发现之地、奇妙之所和灵感之源。 单元知识概览 核心单词 enable;convenience;effect;impact;addicted;recommendatio n;explore;admit;alarm;fancy;trick;identity;variety;creativity; experiment;type;concern;view;accommodation;subscribe; account;ensure;favour;confirm;deliver;harm;argument; replace;concentrate;concerned;rewarding;addition;content; basis;focus;brief;creative;location;imaginary;amazing;access ible 主题素养积累 8 单元知识概览 核心短语 be addicted to;a variety of;be concerned with;in addition;focus on 重点句型 1. as引导原因状语从句2.a time when…3.it作形式宾语4.过 去分词短语作定语5.“no matter+疑问词”引导让步状语从 句 单元语法和 词法 1. 语法:过去将来时2.词法:复合词 单元写作 1. 写个人简介2.单元话题之读后续写：信息技术 续表 主题素养积累 9 语言知识梳理 课后习题 10 1.enable vt.使可能,使发生 (教材P6) enable better communication实现更好的沟通 (1)enable sb to do sth 使某人能做某事 (2)able adj. 有能力的；(某方面)擅长的 be able to do sth 能够做某事，有能力做某事 (3)ability n. 能力；才能 have the ability to do sth 有做某事的能力 语言知识梳理 11 【活学活用】 (1)单句填空 ①Joining a club enables teenagers _________(make) new friends with similar interests. ②With her rich work experience, she was able __________(handle) the difficult project independently. ③She has the _______(able) to manage her time effectively and balance work and life. to make to handle ability 语言知识梳理 12 (2)写作金句 (应用文写作之申请信) I believe my extensive knowledge and work experience _________________________________. 我相信我丰富的知识和工作经验将使我能够将这份工作做好。 will enable me to do the job well 语言知识梳理 13 2.convenience n.方便,便利 (教材P6) provide convenience提供便利 (1)at one's convenience 在某人方便的时候 for (sb's) convenience 为了(某人)方便起见 inconvenience n. 不便利 语言知识梳理 14 (2)convenient adj. 方便的，便利的 It is/was convenient for sb to do sth. 对于某人来说做某事是方便的。 sth be convenient for sb 某物对某人来说是方便的 inconvenient adj. 不便利的 (3)conveniently adv. 方便地，便利地 ［温馨提示］convenient作表语时，不可用人作主语，而要用物作主 语或用it作形式主语；“当你方便的时候”应译成when it is convenient for you，而不是when you are convenient。 语言知识梳理 15 【活学活用】 (1)单句填空 ①People often use credit cards for ____________(convenient) in daily shopping. ②It is convenient for me ________(take) a bus to work because the bus stop is near my house. ③The self-service checkout machine is convenient ____ customers who are in a hurry. ④The park is _____________(convenient) located near the school, making it easy for students to relax. convenience to take for conveniently 语言知识梳理 16 (2)写作金句 (应用文写作之邀请信) We would be delighted if you could attend our graduation party ____________________. 如果您能在方便的时候参加我们的毕业派对，我们会非常高兴。 at your convenience 语言知识梳理 17 3.effect n.效应;影响 (1)have an effect/impact/influence on/upon… 对……产生影响 take effect=come/go into effect 生效;奏效 bring/carry/put…into effect 实施;使生效 (2)effective adj. 有效的;起作用的 (3)effectively adv. 有效地；实际上 语言知识梳理 18 【活学活用】 (1)单句填空 ①One of the most _________(effect) ways to reduce stress is to talk about your feeling with someone you trust. ②Factories that gave out harmful gases were all shut down after the policy came _____ effect. effective into 语言知识梳理 19 (2)写作金句 (应用文写作话题之人物评价) Zheng He's voyages _____________ _________________________________________ China's overseas exchanges and cultural dissemination. 郑和的远航对中国的海外交流和文化传播产生了深远影响。 (have) had a far-reaching effect/impact/influence on/upon 语言知识梳理 20 4.addicted adj.对……着迷的；沉迷的 (教材P6) makes us self-focused/live in an unreal world/addicted to it 让我们以自我为中心/生活在一个虚幻的世界/沉迷其中 (1)be/become/get addicted to 沉迷于；热爱(to为介词) (2)addict n. 对……着迷的人 addiction n. 瘾，入迷，嗜好(常与介词to连用) addictive adj. 使人上瘾的 语言知识梳理 21 【活学活用】 (1)单句填空 ①I find myself _________(addict) to practising yoga regularly, as it helps me relax both physically and mentally. ②It was then that I decided to take action—to overcome my __________(addict) to sugary drinks. ③He should stop playing this game because it is highly _________(addict). addicted addiction addictive 语言知识梳理 22 (2)写作金句 (应用文写作话题之社会现象) Many teenagers _________________ _______________________, spending hours scrolling through their phones every day. 许多青少年对社交媒体上瘾，每天花几个小时刷手机。 become/are/get addicted to social media 语言知识梳理 23 5.recommendation n.建议,提议;推荐 (教材P100) Do you have any recommendation?

Was the soil too dry? Did pests find their way in? During times like these, some frustrated gardeners may wish their plants would just tell them what they need. A new Microsoft-partnered project in the UK is trying to see if that concept can be realized in the real world. 1 2 3 4 课 后 习 题 40 Next year, the Royal Horticultural Society in England will show off an “intelligent garden” that uses an AI model to monitor the garden's environment and inform gardeners when it needs care. Visitors can ask the AI-powered garden questions. The model could then respond with phrases like “I need a bit more water” or “I could use a haircut” depending on data captured in the soil. Apart from the pleasant chat with plants, the garden will provide visitors with a physical representation of the many ways AI could be used to improve sustainability (可持续性) and conservation efforts moving forward. 1 2 3 4 课 后 习 题 When the garden is completed, it will rely on a network of sensors throughout the garden measuring environmental factors like soil moisture and nutrient levels as well as wind and projected rainfall. All of that data is then sent to a specially designed AI model housed in a room at the back of the garden. The model, powered by Microsoft's Azure OpenAI Service, can then analyse those factors and inform gardeners of feeding, watering and trimming (修剪) plants. 1 2 3 4 课 后 习 题 Tom Massey, one of the garden's two designers, described the project as a “unique opportunity”. “I am excited to see how AI can assist gardeners to help make a meaningful impact that will help us all garden and grow more sustainably,” Massey said in a recent interview. 【文章大意】本文是一篇说明文。文章介绍了一个由微软与英国皇 家园艺学会合作的项目，旨在通过AI技术实现“智能花园”，帮助园艺 爱好者更好地照顾植物。 1 2 3 4 课 后 习 题 ( )1.Why does the author mention frustrated gardeners in the first paragraph?
