学生姓名 李梓瑜 性别 女 年级 初一 学科 英语 授课教师 周珍 上课时间 2013年 8月 6日 第（8）次课 课时：2 课时 教学课题 现在完成时 教学目标 理解现在完成时的用法 熟记现在完成时的结构以及过去分词 重点难点 过去分词的记忆、现在完成时含义的理解 教学过程 一、现在完成时的用法： 表示过去发生的某一动作对现在造成的影响或结果。 I have just cleaned my clothes. 表示过去已经开始，持续到现在的动作或状态，也可以表示实质可能继续下去的动作或状态，与表示一段的时间状语连用 I have been here for just over two years. He has worked here since 1989. 现在完成时属于现在时态范围，因此，不能和表示过去的时间状语连用，如yesterday, last night, two weeks ago等， 但可以和never, ever, already, yet, just, for…, since …等连用。 Have you finished your work yet? I have never heard that before. be的现在完成时态。 1）表示一种状态，表示从过去已经开始持续到现在，要与表示一段的时间状语连用. There has been a factory near No. 14 Middle School for several years. 2）表示某人刚从某地回来。 Where have you been? I have been to the library. 3）后加地点，表示某人曾经到过某地。 例如： Have you ever been to West Hill Farm? 但是“have（has）gone （to）+地点”则表示已去了某地，不在说话者所在的地方。 Where is Kate? She has gone to Beijing with her father. 现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始，一直持续到现在。如：I havent seen him for two years.? 但是，像come,arrive,buy等终止性动词不能与表示“一段时间”的状语连用。要用，必须改为“be（在）”等延续性动词来表述。现归纳总结一下由非延续性动词到延续性动词的转换： 非延续性动词 延续性动词 arrive be here begin(start) be on die be dead come back be back leave be away fall ill(sick,asleep) be ill(sick,asleep) get up be up go out be out finish be over put on wear be on open be open join be in be a member of close be closed go to school be a student borrow keep buy have catch(a cold) have(a cold) get to know know begin to study study come to work work open sth keep sth open, come here be here go there be there become be fall asleep be asleep get to/ arrive/reach be (in) get to know know get married be married He has been a soldier for three years. His father has been dead for two years. The film has been on for ten minutes. We have studied English for three years. 结束性动词转换为以下延续性动词或者表示可以延续的状态的短语。 ① arrive at / in sp / get to / reach sp / come / go / move to sp → be in sp / at school / at home / on the farm / be here / be there 1) He got to Beijing five minutes ago.He Beijing for
