( Selfcheck ) 课型 ： 新授 【学习目标】1 New words: extra, topic, writer, be interested in2 To train studentssense of humor.3 To be interested in taking part in activities in an English class.【学习重点】Learn to write a letter to apply for the job.【学习难点】How to write a good letter.【自主学习、合作探究】Task1 疑难解析如何表示“从过去开始一直持续到现在，有可能还要持续下去的动作”。我们采用如下的方法来表示：主语 + have / has been + 现在分词，如：1. She has been skating for four hours.到现在为止她滑冰已经有四个小时了。2. I have been collecting stamps since I was ten years old.我从十岁起就一直在集邮。 在这两个句子中，have 和 has 是助动词，因此把助动词提前，就构成了一般疑问句，在 have 或 has 后面加 not，就构成了否定形式，have not 和 has not 可以分别缩写成 havent 和 hasnt 。如：1. Have you been doing your homework since this morning?从今天早晨起你就一直在写作业吧？（表明写作业这个动作从今天早晨就开始了，一直持续到现在，还要持续下去。）2. I havent been seeing films for a long time.我有很长时间没有看电影了。（表明没有看电影这个动作从过去一直持续到现在，还要继续持续下去。）Task2区分“主语 + have / has been + 现在分词”和“主语 + 动词过去式”这两个句式的不同点及熟练掌握这两个句式的用法。1. “主语 + have / has been + 现在分词”表示动作从过去开始一直持续到现在，并且还要继续持续下去。如：He is a pianist. He has been playing the piano for about twenty years.他是一个钢琴家。他弹钢琴大约有二十年了。弹钢琴这个动作从二十年前就开始了，一直持续到现在，由于他是个钢琴家，那么弹钢琴这个动作还要继续持续下去。这里强调持续，而不是二十年间他一刻不停地在弹琴。又如：I have been collecting snow globes for seven years.我收集里面有雪花的玻璃装饰品有七年了。我有这个爱好，七年间我一直在收集这样的装饰品，但是不等于七年间我别的什么也没干。教师复备栏或学生笔记栏2. “主语 + 动词的过去式”表示过去某个时间已经发生了动作，有比较明确的表示过去的时间状语。如：I did my homework last night.我昨天晚上做的作业。表明“做作业”这个动作发生在昨天晚上，动作没有持续性。Task3 self check 11.
