2014年中国春节首发微信红包。
数据显示，2016春节期间，超过4亿人送出或接收大约80亿个红包。
In China，cash gifts are traditionally given in real red envelopes during weddings and the ChineseNew Year．The WeChat red envelope was launched during the 2014 Chinese New Year with a stipulation(规定)that the amount should be less than 200 yuan．Figures from Tencent Holdings Ltd．(腾讯控股有限公司)show that during that festival period，about 8 million users snapped up 40 million red envelopes．For example，if a person in a WeChat group of 10 sends 100 yuan as a gift and says any one can have a maximum of 20 yuan，the first five to “grab”get the money while the other four miss out．Red envelopes add a sense of atmosphere and strengthen interaction．The amount everybody gets could be different，so it is funny to see the comparisons．During the 2016 Chinese New Year's Eve，more than 420 million people gave or received the envelopes and about 8 billion red envelopes were sent out that day，eight times the figure for the last year's eve．The WeChat red envelope is an innovative(有创意的)way for people to send greetings．It also gets people into the habit of using WeChat payment，because you need to link it to your bank account．For Internet companies，functions such as WeChat payment are an important part of the whole Internet ecosystem，as many other functions such as hailing taxis or shopping are based on online payment．Ⅰ．重点单词1．calculate v t．计算2．universal adj．普遍的；通用的；宇宙的3．simplify v t．简化simple adj．简单的4．operator n．(电脑)操作员；接线员5．logical adj．合逻辑的；合情理的logically ad v．逻辑上；合逻辑地；有条理地6．technology n．工艺；科技；技术technological adj．科技的7．revolution n．革命8．artificial adj．人造的；假的9．intelligence n．智力；聪明；智能intelligent adj．智能的；聪明的10．solve v t．解决；解答11．reality n．真实；事实；现实real adj．真实的12．personal adj．私人的；个人的；亲自的personally ad v．就个人而言；亲自13．total adj．总的；整个的；n．总数；合计totally ad v．完全地；整个地14．application n．应用；用途；申请15．finance n．金融；财经16．mobile adj．可移动的；机动的17．explore v t．& v i．探索；探测；探究explorer n．探险家；勘探者exploration n．探索18．anyhow ad v．(也作anyway)无论如何；即使如此19．goal n．目标；目的；球门；(进球)得分20．happiness n．幸福；快乐happy adj．快乐的；高兴的Ⅱ．核心短语1．have...in common 有共同之处2．compare...with ... 把……与……相比3．from...on从……时起4．go by走过；经过5．as a result结果6．share sth with sb与某人分享某物7．as well as也；和；既……又……8．provide sb with sth为某人提供某物Ⅲ．经典句式1．I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage．我发育缓慢，差不多到了两百年之后，查尔斯·巴比奇才把我制成了一台分析机。

一、课文理解。
唐宋或更早之前，针对“经学”“律学”“算学”和“书学”各科目，其相应传授者称为“博士”，这与当今“博士”含义已经相去甚远。而对那些特别讲授“武事”或讲解“经籍”者，又称“讲师”。“教授”和“助教”均原为学官称谓。前者始于宋，乃“宗学”“律学”“医学”“武学”等科目的讲授者；而后者则于西晋武帝时代即已设立了，主要协助国子、博士培养生徒。“助教”在古代不仅要作入流的学问，其教书育人的职责也十分明晰。唐代国子学、太学等所设之“助教”一席，也是当朝打眼的学官。至明清两代，只设国子监（国子学）一科的“助教”，其身价不谓显赫，也称得上朝廷要员。至此，无论是“博士”“讲师”，还是“教授”“助教”，其今日教师应具有的基本概念都具有了。Fast-reading
2.提高学生的阅读能力；
【课前预习】
重点单词
学法指导：识记P91词汇表单词，然后默写出来。对于不会
的可通过查阅字典。同学吧，相信你们自己的记忆力，加油吧！
1._________v.出现，发生(过去式______过去分词_________）
2._____________adj.电子的_____________n.电
4. deal with (P24)__________________
5. watch over(P24)__________________
单靠“死”记还不行,还得“活”用,姑且称之为“先死后活”吧。让学生把一周看到或听到的新鲜事记下来,摒弃那些假话套话空话,写出自己的真情实感,篇幅可长可短,并要求运用积累的成语、名言警句等,定期检查点评,选择优秀篇目在班里朗读或展出。这样,即巩固了所学的材料,又锻炼了学生的写作能力,同时还培养了学生的观察能力、思维能力等等,达到“一石多鸟”的效果。【合作探究】

人教版高中英语必修2Unit 3 Computers阅读课的教学设计
人教版高中英语必修2Unit 3 Computers阅读课的设计一、前言美国康乃狄格州（简称康州）的外语课程标准系统而全面地涉及了课程标准制定各个方面，对我国英语课程标准的制定具有重要的研究意义和参考价值。
近日，我在完成了《中美两国现行外语课程标准中课程目标比较研究》后，试图从实践角度出发，探讨美国康州外语课程目标体系思想在我国课堂英语教学中的借鉴价值，因此设计了这堂课。
我国《英语课程标准》提出基础阶段外语教育的总目标是，以语言知识、语言技能、情感态度、学习策略和文化意识等五方面素养的发展为基础，培养学生的综合语言运用能力。
美国康州外语课程标准指出成功的语言交流需要“Knowing how, when and why to say what to whom”。
在该课程标准中，外语课程目标以是Communication，Cultures, Connections, Comparisons and Communities 五个领域为核心，总目标是到12年级，学生至少具备一门外语“交际”所需的听、说、读、写能力，并理解所学外语的文化内涵。
“5C”课程目标的内涵如下：首先，至少会用一种外语交流，包括interpersonal，interpretive和presentational三类交流模式；其次，获得文化知识，领会文化内涵。
课程标准中，要求学生能表达自己对所学文化的理解，包括传统习俗（traditions）、有形的文化形态（products），例如艺术、音乐、文学作品等，以及无形的文化形态（perspectives），如人们的观念等等；接着，通过学科交叉获取信息，主要包括interdisciplinary和intradisciplinary两种；再是，对比理解语言和文化本质。
学生通过比较外语和母语，理解母语的本质和本国文化的内涵；最后，参加各种各样的多语社区活动，即指学生在校内外使用外语，通过个体的积极参与来娱乐身心和充实自我。
