Unit 4　INFORMATION TECHNOLOGY 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 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. 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 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 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。 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;recommendation;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;accessible 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 Period One　Topic Talk 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 【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.  (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。 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 (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。 【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.  (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。 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 【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.  (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。 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 【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).  (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。 5.recommendation　n.建议,提议;推荐 (教材P100) Do you have any recommendation?
