The Internet Connects Us学习目标1、掌握本单元词汇及短语。2、复习本单元相关语法: the post continuous tense一、【过去进行时态】过去进行时态的应用:1、构成：主语肯定句：主语+was /were +v-ing.当主语是单数或不可数名词时，助动词用was，当主语是可数名词复数时，助动词用weree.g: Ted was typing his composition at 9:00 yesterday morning.在昨天9点的时候，泰德正在电脑上打他的作文。They were having a meeting at that time last Sunday.他们在上周的这个时候正在开会。否定句: 主语+was /were not + v-ing.疑问句形式: was /were +主语+ v-ing.即be动词提前。e.g：were you writing a letter to your mother at 9:00 Last night?你昨晚9点钟在给你妈妈写信吗？2、过去进行时态的意义及常用的时间状语。(1)过去进行时用来表示“过去某个具体时间点或时间段正在发生某事或持续的状态”，表示这一含意的时间状语有:this morning. At this time. Yesterday. From go to 10. Last night.Eg: I was watching TV at this time yesterday.昨天的这个时间我在看电视.(2)用来描述一个持续动作（常用过去进行时态）发生的同时，另一个瞬间动作（通常是一般过去时的发生，这种情况的时间状语通常是when或while由引导的从句）Eg：It was raining when they left the station.当他们离开车站时天还在下雨.My brother fell when/while he was riding his bicycle.我弟弟在骑车时跌倒了(3)描述一个延续性动作（通常用过去进行时态）发生的同时，另一个延续性动作（通常也用过去进行时）也正在发生，此时的时间状语从句由when或while引导，翻译成“当的时候正在”Eg: I was doing my homework while my mother was cooking. 当我正在做作业的时候，我的妈妈还在做饭.二、【合作探案】1、make it easy for sb. to do sth.对某人来说做某事很容易。e.g：Modern transport make it easy for people to travel.现代化的交通工具，使人们容易出门旅游2、a good place to live.一个好的居住的地方.这一短语中的不定式to live作定语，修饰名词place。注意，不定式作定语时，往往与被修饰的名词或代词构成逻辑上的主谓或动宾关系，构成动宾关系时，不定式动应使用及物动词，不及物动则应该加一个适当的介词.Eg: The student had no paper to write on.那个男孩没有纸写字.The students have a lecture to listen to.学生们有一个报告要听.3、常用作形容词，应为“慢的”，用作动词，意为“使慢下来”.e.g: They are slower than planes.它们比飞机慢.Slow down意为“慢下来，使慢下来，使减速”e.g: The train slowed down as it came to the station.火车进站时，开始慢了下来.The machine slowed down and stopped.机器逐渐减慢速度，终于停下来.4、stop sb.
