1 、现在完成时用来表示过去发生或已经完成的动作对现在造成影响或后果。也就是说，动作或状态发生在过去但它的影响现在还存在，强调的是现在。 例如：Ihave already posted the photo. 我已经把照片寄走了。强调post对现在的影响“照片不在这里”。 2、现在完成时可以用来表示发生在过去某一时刻的，持续到现在的动作（用行为动词表示）或状态（be动词表示），常与for（+时间段），since（+时间点或过去时的句子）连用。谓语动词必须是延续性动词。 例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。（动作起始于1978年，一直住到现在，可能还要继续住下去。） 注意：for和since的用法。 ①for+时段为…时间 ②since+过去一个时间点（译为：自从……以来） ③since+时段+ago ④since+从句（过去时） ⑤It is+时段+since+从句（过去时） 注：瞬间动词（buy,die,join,lose……）不能直接与for 或since 引导的时间段连用。要改变成延续性动词。变化如下：e/arrive/reach/get to-----be in go out----be out finish----be over open----be open
英语现在完成时 现在完成时表示到说话时为止（或到现在为止）已经发生或完成了（不一定结束）的动作或状态。过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态。 a. 现在完成时的句型 ①肯定句：主语+has/have+动词的过去分词+宾语（或者其他） ②否定句：主语+haven’t/hasn’t+动词的过去分词+宾语 ③一般疑问句：Have/Has+主语+动词的过去分词+宾语（或者其他）.（末尾用问号） b. 现在完成时的用法 1) 表示影响 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，同时说话者强调的或感兴趣的就是这个影响或结果，如汉语说”他已离开这个城市了”，其中的”离开”肯定发生了，它对现在的影响或结果就是”他现在已不在这个城市了”；又如汉语说”有人把窗户打破了”，显然”打破窗户”这一动作发生在过去，并且在过去已经完成了，但说话人强调的重点是打破窗户对现在的影响–窗户现在仍是破的。如： He has been away from the city.他已离开这个城市。(结果：他不在这个城市。) Someone has broken the window.有人把窗户打破了。(结果：窗户仍破着。) I have lost my pen.我把钢笔丢了。(结果：我现在无钢笔用。) He has finished his work.他把工作做完了。（结果：他现在可以做其他的事了。） 2) 表示持续 该用法的现在完成时表示一个过去发生的动作或开始的状态在过去并未完成或结束，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)，如汉语说”他在我们学校教书已有30年了”，显然”他在我们学校教书”是从30年前开始，并且一直教到现在，已经持续了30年；又如汉语说”自上个星期以来他一直很忙”，显然”忙”是从上个星期开始的，并且这一”忙”就一直忙到现在。如： He has taught in our school for 30 years.他在我们学校教书已有30年了。 He has been busy since last week.自上个星期以来他一直很忙。 He has worked for us ever since he left school.他离开学校以后就一直为我们工作。 3) 表示重复 即表示从过去某个时间直到现在的这个时间范围内不断重复发生的动作或情况，并且这个不断重复的动作有可能继续下去，也有可能到现在就结束。如：
高中英语语法《现在完成时的被动语态》教学设计 一、教材分析 本节课的授课内容为被动语态中的一个重点也是难点的内容：现在完成时被动语态的学习及其应用。对于该内容学生半知半解，加上语法容易让人觉得枯燥，学生对此内容有排斥畏难心理。所以教学中将语法知识的传授和语言基本技能的学习结合到一起，注重学习语法与语言的运用。采用任务型教学法、情景教学法和小组合作探究学习法，让学生亲身去感知、领悟知识和运用知识，从而扩大课堂的语言输入量及学生的语言输出量，使其内容更加丰富，降低了语法学习的难度，同时也使语言学习和运用语言的过程成为一种栩栩如生的互动体验，提高了学习效率。 二、学情分析 授课对象为高一级的学生，他们来自全区各地初中，大部分学生的基础知识仍然较为薄弱，运用英语进行交际活动的能力较差，主动学习的动力不够，然而他们学习比较认真，渴求知欲旺盛，思维比较活跃。部分学生的基础较好，能主动配合老师。所以只有设臵使他们感兴趣的活动，利用发生在学生身边的事情——教室的环境布臵和学校艺术文化节作为语法学习的载体，因材施教，让学生明白所学语言知识的实用性，这样才能激发学生学习的积极性，并在师生互动、生生互动中实现教学任务和目标。 三、教学目标 知识与技能：1.让学生弄清楚现在完成时被动语态的结构和用 法； 2.重点是现在完成时被动语态的应用。 过程与方法：1.培养学生自主学习、协作学习和探究的能力； 2.培养学生分析问题、解决问题、归纳问题的能 力。 3.提高思维能力和运用英语的综合能力。
情感价值观：通过本节课的学习，培养学生热爱学校积极参与 学校活动的情感。 四、教学重点和难点 现在完成时被动语态的基本构成与实际应用。 五、教学策略和方法 本节课的教学以学生为中心，以教室的环境布臵和学校艺术文化节为载体，使课堂教学过程成为学生自主地进行信息加工、知识意义构建、归纳能力发展的过程。教师在教学过程中则适时介入，引导、启发、组织、帮助、促进。随堂进行小组指导，一方面参与学生的讨论，更给学生以个别辅导，以帮助学生解决学习过程中的难题。通过演示法把制作的课件、学生的作文等显示给学生看，便于学生对知识的把握，并从中获得启迪，从而解决问题。通过小组协作法分析问题、解决问题，从而内化而形成学习成果，并将其在全班学生中展示，使学生获得成功的喜悦，从而激发学生的后续学习热情。通过任务驱动教学法将所要学习的新知识隐含在语言操练之中，学生通过对呈现的图片进行分析、讨论，并在老师的指导、帮助下用本节课的语法对图片进行描述，以达到对语法项目的操练，最后通过任务的完成而实现对所学知识的意义建构。 六、板书设计 现在完成时被动语态的基本结构：have/has been done 七、教学过程 Step1 Revision (复习)（6分钟） 本单元学习的话题是计算机，计算机的应用很广泛，让学生在阅读里面找出介绍计算机应用的句子，并齐读句子：?The computers have been used in communication, finance and trade. ?The computers have been put into robots. ?It has been used to make mobile phones as well as help with

高一专题系列一被动语态 ●学而时习 语态是动词的一种形式，用以说明主语与谓语动词之间的关系。英语的语态共有两种：主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。 ●知识点精讲透析 ●考点一主动语态“变性”被动语态 1、主动语态变为被动语态的步骤： (1) 将主动句的宾语变为主语，如果主动句的宾语是代词，需变为主格。 (2) 将动词改为“be+过去分词”，be与新主语的人称和数一致，时态不变。 (3) 将主动语态的主语前加by放在谓语动词后，如果原主语是代词，要变为宾格。如： They held a meeting yesterday. → A meeting was held（by them）yesterday. 他们昨天开会了。昨天举行了一个会议。 They won’t forgive me. → I won’t be forgiven by them. 他们不会原谅我的。我不会被他们原谅的。 2、主动语态变为被动语态的注意事项： (1) 主动句中的主语如果是people, we, you, they, somebody等含糊地表示“人们”、“大家”等，变为被动句时，通常删去“by…”，除非强调原主语。如： They set up this hospital in 1975. → This hospital was set up in 1975. 这所医院建于1975年。 Only he can finish the job. 只有他能完成这项工作。→ The job can be finished only by him.这项工作只能由他来完成。 (2) 含有双宾语，即直接宾语和间接宾语的句子，每个宾语都可变为被动语态的主语，即其被动语态有两种形式，但多以间接宾语作主语。 Jack told us the truth.杰克告诉了我们真相。We were told the truth by Jack. The truth was told (to) us by Jack. (3) 含有宾语+宾语补足语的句子，变成被动句后原来的宾语补足语就成了主语补足语了；注意：不带to的不定式作宾语补足语时，变成被动时要加上to。 I heard Emily sing the song just now. → Emily was heard to sing the song just now. 我刚才听见艾米莉唱这首歌了。 (4) 含有宾语从句的主动句变为被动句，通常用it作为被动结构的先行主语，把宾语从句后置。 We have determined that the plan should be carried out soon. It has been determined that the plan should be carried out soon. 我们决定这项计划必须马上实施。 (5) 双重被动结构: 当某人或物成为两次动作的承受者时，要用双重被动结构。如： Parents often ask their children to do too much homework. The children are often asked to do too much homework. Too much homework is often asked to be done by the children.
