Present the Present Perfect Tense.巧记口诀： have(has)在前面， 过去分词在后边， 以前(befor
6、e) 从来不(never) 出现， 最近(recently) 曾经(ever) 一(once) 两遍(twice)，呈现语法口诀，让学生在朗朗的读书声中轻松克服语法难点，掌握语法重点。究课内探究 自从(since) 刚刚(just) for 一段， 今天(today) 已经(already/yet) 很明显。Has she found her car key yet? I havent heard from Daniel recently.Summary：1、已完成用法(影响性用法)：该用法的现在完成时表示一个过去发生的动作在过去已经完成，并且这个过去发生并完成的动作对现在有影响或结果，同时说
7、话强调的或感兴趣的就是这个影响或结果。如：2、未完成用法(持续性用法)：该用法的现在完成时表示一个过去发生的动作并未在过去完成，而是一直持续到现在，并且有可能继续下去(也可能到此结束)。他们结婚已经 10年了。They have been married for ten years.How long have you lived here? have been to 和 have gone to的用法区别She has been to Europe twice. She has gone to Europe. 两者均可后接地点，前者表示去过某地，通常可与表示次数的状语连用；后者表示到某地去了，
8、强调说话的当时去某地的人不在场。B. Present the passive voice.一般现、过用 be +V.过去分词，be有人称、时、数变。完成时态 have(has) done，被动将 been加中间。一般将来 shall (will) do，被动变 do为 be done。结合口诀，简要讲解语法，帮助学生在理解的基础上进行记忆。情、助、有、是妥安排， 一律随新主语变。否定助后加 not， 疑问一助置主前。一般情助加 be done， 双宾多将间宾变。复合宾语宾变主， 宾补、主补相应变。例：History is made by the people.

10、 and the passive voice.Typical mistakes:一、过去式和过去分词混淆。例：Have you ever _ _(take) a train? take的过去分词是 taken, took是过去式，不能混淆。答案：taken二、have 与 has易用混 例：It _(be ) more than three years since Jim _(leave) here.现在完成时与一般现在时一样也有单三人称的变化，当单三人称作主语时用 has, 一般人称作主语时用 have答案：has been三、延续性动词与短暂性动词易弄错利用投影仪呈现学生练习答案，讲解学生
11、练习中出现的典型错误，以及学生平时的易错题，防患于未然。通过课内探究，学生能够熟练运用本课所学来完成练习，达到提高的目的。例：The books may_ for two weeks.A. be kept B. be borrowed C. keep D. borrow在肯定句中，与 since或 for引出的时间状语连用的是延续性动词，不能是短暂性动词，但在否定句中短暂性动词也是可以的。E.g. I havent bought clothes for one year. 在此题中 borrow是短暂性动词，不能与 for+时间段连用，须把它改成相应的延续性动词。如 stop be over
12、等。此题中 borrow是短暂性动词不能使用。只能用 be kept。这两种词的转换是学习现在完成时需要注意的。答案：A四、have been to 与 have gone to 易弄混( ) -Where _you _? I called youjust now, but nobody answered the phone.-I _ to the hospital. My grandpa _ there to see a doctor. Nobody was in just now.A havebeenhave beenhas gone B havegonehave beenhas gone
13、C havebeenhave gonehas gone D havebeenhave beenhas been “have been to+地点“ 是表示曾去过某地，但此刻不在那儿（即在说话的地方）。而“have gone to+地点“ 是表示去某地了，此刻在路上或已经到了那个地方（即不在说话的地方）。注意：这两个句式后接副词时，需省 to。E.g. He has gone there. 答案：A五、忘记把 already变成 yet例：I have already finished my homework.(变一般疑问句)Have you already finished your home
14、work?现在完成时态中，肯定句中有 already，变否定句或疑问句时通常要改为 yet答案： Have you finished your homework yet?课内探究导练 Step IV: Production & Activity每组学生从三个纸盒中分别拿一张现在完成时时间状语，让他们或背诵或运用复习的时态和语态造出一些有趣的句子，加深理解，提高能力，让学生学中乐，乐中学。课后提升Step V: Assignment一、课后反馈二、课后练习题情况反馈：教师对课后练习题进行批改检查，然后将具体情况记录在教案上，主要包括整体完成情况、学生答题存在的主要问题及形成原因，同时设计适量的有针对性的变课后反馈（见学案）及时的肯定的鼓励性的评价和批语有助于增强学生学英语的信心。式训练及时纠偏。Blackboard design (板书设计)the Present Perfect Tense(现在完成时) the Passive Voice（被动语态）have / has + V.pp be(am、is、are、was、were)+ V.pphave/has been & have/has gone have/has been + V.pp人不在那儿 人不在这儿 will/shall/should/can/must/may+ V.pp
