编制： 谭云清 2012-12-13高一M2U1现在完成时及现在完成进行时教案1Learning goals：1，掌握现在完成时和现在完成进行时的定义，结构，及用法 2，区别现在完成时与过去式；区别现在完成时和现在完成进行时。 3，现在完成时及现在完成进行时的运用。Teaching steps: Step 1【理解】（参见学导P17）现在完成时态（包含已完成和未完成两种含义）含义：1，“已完成”用法：现在完成时表示的动作在说话之前已完成, 但对现在造成影响。句中没有具体的时间状语。Li Ming has just turned off the light.李明刚刚把灯关上。（说明现在灯关上了）Ive finished my homework now.现在我已经做完作业了。（说明可以交作业或做别的了） 2，“未完成”用法：表示过去发生而持续到现在(也许还会继续下去)的动作或状态。这一用法通常都要与for，since等开头的表示一段时间的状语连用。He has lived here for 30 years.他住在这儿三十年了。（现在还住在这儿）How long have you studied English？你学英语多久了？（现在仍在学）She has studied English since 1998.Step2:【归纳】1，现在完成时的谓语结构：have/has + Ved2，for后接的是时间段；since后接的是时间点，而且since从句用的是过去时间。【理解、记忆】1，现在完成时不能和具体的过去时间（last week, just now, in 1949,yesterday等）连用，但可以和不明确的时间状语连用。（如：already/yet, recently/lately, ever/never, just, twice/three times等）连用。It has been cold this winter. (说话时还是冬天。)2，in/during the past /last+复数名词 是完成时态的标志。There have been great changes in our hometown in the past few years.3，It/This is the first/second timethat结构中的从句部分，用现在完成时。4、have been(to)表示“去过某地（现在已经回来了）”。have gone(to)表示“去某地了（说话时某人不在当地）”，常用于第三人称。如：They have been to Beijing twice.他们去过北京两次。（回来了）He has gone to Beijing . 他去北京了。(没回来)5，瞬间动词或短暂性动词不能和表一段时间的时间状语连用。如：come, go, arrive, reach, hear, close, leave, begin, start, lose, buy, fall, join, die, get up等。但如果要保留表一段时间的时间状语，必须将动词改为延续性动词，常与for+时段、since+过去一个时间点（过去 从句）的时间状语连用。He has died for five years. () He has been dead for five years. () He died five years ago. ()Step3：二、现在完成进行时【理解】定义：现在完成进行时表示动作从过去某一时间开始，一直延续到现在，可能还要继续下去。She has been talking to me since she saw me. 她自从见到我就一直和我说话（现在还正在说）Step4：【运用】练习：一、句型转换1、He has never cooked, hasnt he?（改成反意疑问句）2、Miss Gao left an hour ago.
