Text in Book 2 Unit 3 ---Who am I?
These changes only became possible as my memory improved. First it was stored in tubes, then on transistors and later on very small chips. As a result I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn’t believe it! But I was always so lonely standing there by myself, until in the early 1960s they gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web.
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。
