Unit 3 Period One（课件）-2018版步步高学案导学与随堂笔记英语（人教版必修2）全国版

Unit 3　Computers Personal computers and Internet give people new choices about how to spend their time.Some may use this freedom to share less time with certain friends or family members，but the new technology will also let them stay in closer touch with those they care most about.E-­mail makes it easy to work at home，which is where I now spend most weekends and evenings.My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office.This lets me share more time with my young daughter than I might have if she’d been born before electronic(电子的) mail became such a practical tool. 话题导入 With e­-mail，you just write one note about your experience，at your convenience(方便)，and address it to all the friends you think might be interested.They can read your message when they have time，and read only as much as they want to.They can reply at their convenience，and you can read what they have to say at your convenience.E-­mail is also an inexpensive way to stay in close touch with people who live far away.More than a few parents use e-­mail to keep in touch，even daily touch，with their children at college.We just have to keep in mind that computers and the Internet offer another way of staying in touch.They don’t take the place of any of the old ways. 根据上文判断正(T)误(F) 1.E­-mail makes it very hard to work at home.( ) 2.The author always works at the office.( ) 3.If you stay in touch with people who live far away，e­mail will help you save money.( ) F F T 基础自测　 课文预读 内容索引 要点探究 当堂达标 Period One　Warming Up，Pre­-reading & Reading 基础自测 1. vt.计算 2. adj.普遍的；通用的；宇宙的 3. vt.简化 adj.简单的 4. adj.合逻辑的；合情理的 adv.逻辑上；合逻辑地；有条理地 5. n.工艺；科技；技术 adj.科技的 Ⅰ.重点单词 calculate universal simplify simple logical logically technology technological 6. n.智力；聪明；智能 adj.智能的；聪明的 7. vt.解决；解答 8.
