Section Ⅱ　Lesson 1 [对应学生用书P8] 原文呈现 I'm a...digital① native②！ The online world is a big part of my life.I'm a “digital native”—I've been using the computer since I was a kid.[1] [1]have been doing sth 现在完成进行时。 I do a wide range③ of things online.Besides doing all my schoolwork，I chat with my friends，watch films and read the daily news and other interesting articles; I also shop for various④ things online，such as⑤ books，computer hardware⑥ and other necessities⑦.It's so convenient⑧ to be able to compare⑨ the quality⑩ and prices from different online shops before I buy.I also play computer games from time to time⑪ and I even play tennis on my television screen in my living room⑫！ My parents are worried that I may become an“Internet addict⑬”．They think I'm playing computer games all the time⑭ and I chat too much with online friends.According to⑮ them，there is a danger⑯ that I may not be able to tell whether these friends are real friends.[2]My mum keeps telling⑰ me to go out with my school friends instead.Maybe she's right.It's important to meet friends in person⑱ from time to time，not just on social media⑲ .[3]Actually⑳，I do know I need to drag myself away from the online world sometimes，especially because real life can be just as interesting. [2]that引导的是danger的同位语从句，whether引导的是宾语从句。 [3]固定句型It is/was＋adj. to do sth“做某事是怎么样的”。 I'm a．..go­getter! Senior secondary school is a new start.Studying is definitely a big part of my life.[4]I tend to set a goal for every subject at the beginning of each term.My aim is to do well in every subject this term.Biology is my favourite subject，and my target is to prepare myself for my degree in biology at university.I am always attentive in all classes and think actively，so that I can have more free time to do other things that I'm interested in after school.[5] [4]动名词studying作主语。 [5]so that“以便，为了”，用于引导目的状语从句。 I like reading books of all kinds.I have a top 10 reading list and I try to keep it updated.Meanwhile，I'm an active member of my school's long­distance running team and volunteering club.It always makes me excited to work hard and achieve a team goal together.[6] [6]make＋宾语＋宾补结构，意为“使某人/某物处于某种状态”。 To achieve all I want，I must use my time well.[7]At school，I do my homework when I have spare time.After school，I try to use any possible time to revise the things I have learnt during the day.For example，it usually takes me 20 minutes to get home by bus.[8] I often use the time to review English words.As the popular saying goes，“Every minute counts！”[9] [7]此句为定语从句，省略了关系代词that。 [8]It takes/took sb time/money to do sth “做某事花费了某人多少时间或金钱”。 [9]as the popular saying goes“常言道”，as引导定语从句，意为“正如，正像”，go此处意思是“说，流传”。 Set a goal and get ahead！ 语料积累 ①digital adj.数字的，数码的 ②native n.本地人 ③range n.一系列；范围 a wide range of 广泛的，各种各样的 ④various adj.各种各样的；多种(类型)的 variety n.种类 ⑤such as 例如 ⑥hardware n.(计算机)硬件 software n.(计算机)软件 ⑦necessity n.必需品 necessary adj.必要的 ⑧convenient adj.方便的，便利的 it is convenient (for sb) to do sth(对某人来说)做某事是方便的 ⑨compare v.比较 compare A with B 把A与B相比 ⑩quality n.质量，品质 quantity n.数量 ⑪from time to time 有时；偶尔；间或 ⑫living room 起居室 ⑬addict n.对……着迷的人 ⑭all the time 一直，总是 ⑮according to 按……所说，根据 ⑯a danger 一件危险的事，一个危险的人 ⑰keep telling 一直说 ⑱in person亲自 ⑲media n.新闻媒体，大众传播媒介(总称) social media 社交媒体 ⑳actually adv.实际上，事实上 drag vt.拖，拉 drag sb away from doing sth 不要做某事 tend to do sth 易于做某事 goal n.目标，目的 at the beginning of 在……开始 aim n.目的，意图 v.力求达到 aim to do sth 旨在做某事 term n.学期 target n.目标 prepare sb for sth 使某人为某物做好准备 attentive adj.专心的 attention n.注意力 of all kinds 各种各样的 update vt.更新 meanwhile adv.与此同时 distance n.距离，间距 volunteer v.自愿；志愿 n. 志愿者 spare time 空余时间 revise vi.&vt.复习 saying n.格言，谚语 ahead adv.在前面；向前 get ahead取得成功，获得成功 参考译文 我是……数字原住民！ 网络世界是我生活的重要组成部分。我是“数字原住民”，——从还是孩子的时候，我就一直用电脑。 我在网上做很多事情。除了做我所有的功课，我和我的朋友聊天，看电影，读每日新闻和其他有趣的文章；我也在网上买各种东西，比如书、电脑硬件和其他必需品。购物前，能够比较不同的网络商店的质量和价格是非常方便的。我有时也玩电脑游戏，我甚至在我卧室的电视屏幕上打网球！ 我父母担心我会成为一个网迷。他们认为我一直在玩电脑游戏，和网友聊天太多。在他们看来，我可能无法判断这些人是否是真朋友，那是危险的。妈妈一直让我和学校的朋友出去玩而不是在家打游戏。也许她是对的。经常和朋友见面很重要，而不仅仅是在社交媒体上。事实上，我非常清楚我有时需要强迫自己不上网，特别是因为现实生活也可以一样有趣。 我是……积极进取的人！ 高中是一个新的开始。学习绝对是我生活中很重要的一部分。我倾向于在每学期开始时为每门课程设定一个目标。我的目标是这学期每门功课都考好。生物是我最喜欢的科目，我的目标是为我的大学生物学位做准备。我在所有课上总是专心听讲并积极思考，这样放学后我就有更多可支配的时间做我感兴趣的事情。 我喜欢读各种各样的书。我有一个十佳书籍的阅读清单，我尽量保持更新。同时，我也是学校长跑队和志愿者俱乐部的积极分子。一起努力工作并实现一个团队目标总是让我感到兴奋。 为了实现所有我想要的，我必须好好利用我的时间。在学校，我有时间就做作业。放学后，我试着利用任何可能的时间来复习我在一天中所学的东西。例如，我坐公共汽车回家通常要花20分钟。我经常利用这段时间复习英语单词。常言道：“分秒必争！” 设定一个目标，并获得成功！ [对应学生用书P10] Ⅰ.重点单词 基础单词 1．lifestyle n. 生活方式 2．chat vi. & n. 闲谈，聊天 3．surf vi.&vt.冲浪 4．laptop n．笔记本电脑，便携式电脑 5．digital adj.数字的，数码的 6．native n．本地人 7．range n．一系列；范围 8．hardware n．(计算机)硬件 9．quality n．质量，品质 10．addict n．对……着迷的人 11．media n．新闻媒体，大众传播媒介(总称) 12．drag vt.拖，拉 13．goal n. 目标，目的 14．aim n. 目的，意图；vi. 力求达到 15．target n．目标 16．update vt.更新 17．meanwhile adv.与此同时 18．revise vi.&vt.复习 19．saying n．格言，谚语 20．ahead adv. 在前面；向前 21．teen n．少年，十几岁的孩子 拓展单词 1．voluntary adj.志愿的；服务的；自愿的→volunteer vi.&vt.自愿；志愿；n.志愿者 2．engine n．引擎→engineer n．工程师 3．definitely adv.确切地，肯定地→definite adj.确切的，肯定的 4．necessity n．必需品→necessary adj.必要的； 必然的→necessarily adv.必要地；不可避免地 5．vary vi.变化，不同→variety n．多样；多样化→various adj.各种各样的；多种(类型)的 6．actual adj.实际的，真实的→actually adv.实际上，事实上 7．distance n．距离，间距→distant adj.远的；疏远的 Ⅱ.重点短语 1．surf the Internet 网上冲浪，浏览因特网 2．search engine 搜索引擎 3．from time to time有时；偶尔；间或 4．living room起居室 5．according to 按……所说，根据 6．in person 亲自 7．social media社交媒体 8．tend to do sth 易于做某事 9．get ahead 取得进步，获得成功 Ⅲ.句式语境 1．has/have been doing sth I've been using the computer since I was a kid. 我从还是孩子的时候就一直用电脑。 2．It作形式主语 It's so convenient to be able to compare the quality and prices from different online shops before I buy. 我在购物前能在不同的网络商店比较质量和价格是非常方便的。 3．that引导同位语从句 According to them，there is a danger that I may not be able to tell whether these friends are real friends． 对他们来说，我可能不能够判断这些人是否是真朋友，这是危险的。 4．do强调谓语，用来加强语气 Actually，I do know I need to drag myself away from the online world sometimes... 事实上，我非常清楚我有时需要强迫自己不上网…… 5．make＋宾语＋宾补 It always makes me excited to work hard and achieve a team goal together. 努力工作和实现团队目标让我感到非常兴奋。 [对应学生用书P11]Ⅰ.Read Text 1 and finish the following exercises.
