参考词汇：微信WeChat, 红包red envelope精彩美文With the popularity of smart phones and the development of modern technology, people will choose to send red envelopes through WeChat to their close friends or family members to express their best wishes when their family members or friends will have their birthdays or be at festivals, especially some faraway ones.Compared with expressing their best wishes in person, expressing their best ones online have many advantages. Firstly, it's more convenient and quicker to send and receive them as well, without being limited by time and space. Secondly, they can also express their best wishes in words and pictures and so on, which is more interesting and lively. Most importantly, it also can save people much time especially in such a busy society.In my opinion, I like this kind of wishes. I have to say it is just the Internet that is making our life more colourful and comfortable.名师点睛1．文章体裁：议论文。

人教必修二UNIT 3核心考点专讲专练【考点剖析】arise vi. (arose, arisen)出现;发生;起身;起床;上升[温馨提示]arise为不及物动词,没有被动语态。
arise 作“发生;出现〞讲时,主语多为抽象名词,如argument,problem,quarrel,question等。
【易混辨析】arise, arouse,rise与raise原形过去式过去分词现在分词含义arise (vi.) arose arisen arising在现代英语中主要用于借喻,指“出现;发生;产生〞。
arouse(vt.)aroused aroused arousing 指“唤醒;激起〞,后常跟抽象名词。
rise (vi.) rose risen rising使用范围较广,指“升起;上升;增长〞,也可指“起立;起床;地位升高〞等。
raise (vt.)raised raised raising用在句中,后面需跟宾语。

(1)强调主句动作发生在从句之前,意为“不等……就……〞。
(2)在“It+be+时间段+before从句〞中,意为“……之后才……〞。
(3)在“It+be+否认形式+long+before从句〞中,意为“……不久就……〞。

人教版新教材必修二unit3 The computer 语法：现在完成时的被动语态用法讲解
人教版新课标必修二Unit3 The computer语法现在完成时的被动语态用法讲解【学习目标】1．现在完成时被动语态的结构2．现在完成时被动语态的主要用法3．使用现在完成时的被动语态需要注意的问题【课前预习】1．什么是语态？语态是表示主语和动词之间的主动关系或被动关系的动词形式。
英语动词有两种语态：主动语态和被动语态。
主动语态表示主语是动作的执行者（施动者），被动语态表示主语是动作的承受者（受动者）。
2．对现在完成时被动语态的理解现在完成时被动语态的结构就是现在完成时态和被动语态结构的叠合，即“have + been + 动词过去分词”。
试比较以下几组句子的谓语结构：1）主动句：He has repaired the machine for two hours. 他修理这台机器已有两小时了。
被动句：The machine has been repaired for two hours. 这台机器已修了两小时了。
2）主动句：The teacher has borrowed the books. 老师把那些书借走了。
被动句：The books have been borrowed by the teacher. 那些书被老师借走了。
【教学过程】一、现在完成时被动语态的构成1．现在完成时被动语态的肯定式由“have ／has ＋been ＋及物动词的过去分词”构成。
例如：Two windows have been broken．两个窗子被打破了。
2．现在完成时被动语态的否定式由“have ／has ＋not＋been ＋及物动词的过去分词”构成。
例如：The car has not been repaired．这辆汽车还没有修好。
3．现在完成时被动语态的一般疑问式由“Have／Has ＋主语＋been＋及物动词的过去分词”构成。
例如：①─Has her work been finished？她的工作完成了吗？─Yes，it has．是的，完成了。
高中英语Unit3 Computers文章 什么是机器人人教版必修二
word
什么是机器人
美国是机器人的诞生地，早在1962年就研制出世界上第一台工业机器人，比起号称"机器人王国"的日本起步至少要早五六年。
经过30多年的发展，美国现已成为世界上的机器人强国之一，基础雄厚，技术先进。
讲到什么是机器人时，我们大多数人都看到过电影或书本里描绘的外形酷似人类的机器人，这是机器人的一种表现形式。
可机器人并不一定非得是这样的。
事实上，机器人的形状各式各样。
我们身边到处都有机器人。
机器人能够代替人类完成重复乏味或者危险的工作，提高我们的生活品质和工作效率。
机器人技术综合机械工程、电子工程、传感器应用、信息技术、数学、物理等多学科知识，代表着一个国家的高科技发展水平。
实际意义上的机器人，应该是“能自动工作的机器〞有的功能很简单，有的就复杂得多。
例如：家里的供暖系统，我们只需做最初设定接下来它就能自己工作，我们身边的大多数家用电器都是这样。
自动温控系统的元器件遍布于整座智能化大楼。
