现在完成时的被动语态(学导练公开课)
现在完成时的被动语态(学导练公开课)
现在完成时的被动语态
现在完成时是英语中常用的一种时态，用来表达过去某个时刻开始的动作或状态一直延续到现在，或者产生的结果对现在造成的影响。被动语态则是用来强调动作的接受者或被动者。本文将探讨现在完成时的被动语态的用法和构成。
一、现在完成时的被动语态的构成方式
现在完成时的被动语态由“助动词have/has+been+过去分词”构成。其中，have/has表示动词have/have的形式，been是助动词be的过去分词形式，过去分词则表示被动动作的主语，根据实际情况加上-ed或其他形式。
二、现在完成时的被动语态的用法
1. 强调行为的接受者或被动者：被动语态可以使句子的主语变为动作的接受者或被动者，从而突出动作的承受者的重要性。例如：- Active voice (主动语态): The workers have built a new bridge.
- Passive voice (被动语态): A new bridge has been built (by the workers).
2. 强调动作的结果：现在完成时的被动语态可以强调动作或状态的结果对现在造成的影响。例如：
- Active voice (主动语态): The company has launched a new product.
- Passive voice (被动语态): A new product has been launched (by the company).
3. 强调动作的连续性：现在完成时的被动语态可以强调动作或状态从过去某个时刻开始一直延续到现在。例如：

already和yet的区别
already常用于肯定句中或句末； yet常用于一般疑问句或否定句末。 但表惊讶时already也可用于疑问句。 e.g. 1.Tom has already finished his work. 2.Tom hasn’t finished his work yet. 3.What!Have you already finished it?
注意点二：短暂性动词与现在完成时 短暂性动词在肯定句、疑问句中不能与表示时间段 的短语连用。这些动词是： buy , borrow ,become, begin, arrive, come, die, fall, finish, get to know, go, join, leave, marry等。为了表述相同的意思， 我们常用相应的延续性动词have，keep等来代替短 暂性动词。如： 我买这个手机有三年了。

英语语法现在完成时PPT课件
（1）将非延续性动词转化为相应的状态 动词。所谓状态动词就是指这一动作发生 后接下来所呈现的状态。如： He has been asleep for an hour. （fall asleep,“入睡”为短暂动作，但be asleep“睡着”则为状态动词，可延续。） His father has been dead for three years. （die为短暂动词，“死”后的状态可用 “be dead”这种系表结构来描述，可延 续。）
延续性语境中的非延续性动词的使用 在具体的语言环境中，往往会出现非延续性动 词与时间段相连用的情况。由于受汉语影响，往往 错误地直译为： He has fallen asleep for an hour. 他睡了一小时了。（×） His father has died for three years. 他父亲去世三年了。（×） 当出现这种情况时，我们往往采取以下解决方法：
现在完成时用法三:
• 现在完成时和一般过去时都能表示过去发 生过的动作，但现在完成时表示过去动作 对现在的影响，并且表示这一动作已完成 或还可能继续下去；而一般过去时与现在 的情况没有联系，仅表示过去的动作，且 这一动作到说话时已终止。因此现在完成 时不能与表示明确的过去时间如when， in1949，yesterday，last week等的状语连 用，并且用when或where对这些时间和地 点状语提问时，一般只用一般过去时。
现在完成时讲解讲课教案
如何使用现在完成时
同学们我们已经学习了现在进行时、一般现在时、一般过去时、一般将来时这4种时态的用法，但这4种时态还不能满足我们表达的需要。比如：表示“某人过去曾经做过某事”或者“某人做某事多久”，以上五种时态就派不上用场了。这时，我们可以用一种新的时态——现在完成时表示。
一、现在完成时的构成
（一）肯定式
主语＋助动词have ／has ＋过去分词＋其它
说明：这里的have ／has是助动词，没有什么具体意义。当主语是第三人称单数时助动词用has，其余人称一律用have。has，have的缩略式分别为's或've。规则动词过去分词的构成与过去式的构成方式一样，不规则动词可参看不规则动词表。实例：
1）I've just copied all the new words ．我刚抄写了所有的生词。(表示不要再抄了)
2）She has lost her books ．她丢失了她的书。（表示到目前为止还没有找到）
(如果用过去时：She lost her books . 则强调书是过去丢的这一动作，而不知现在有没有找到)
3）We've just cleaned the classroom ．我们刚好打扫了教室。（表明现在教室是干净的）
（二）否定式
主语＋助动词have ／has＋not＋过去分词＋其它
说明：现在完成时构成否定句时，只需在助动词have ／has后面加not就行。have not，has not的缩略式分别为haven't ，hasn't。另外，肯定句中有some，already时，改为否定时要分别改成any，yet。实例：

情态动词+have done 的用法
情态动词+have done 用于表达某件事情已经完成，且强调动作的过程。
例如：I have finished my homework.（我已经完成了我的作业。）

情态动词+be done 的用法
例如：The report is being prepared.（报告正在准 备中。）
情态动词+be done 用于表达某件事情正在被完成， 且强调动作的进行状态。
情态动词+be done 可用于各种情态动词，如can、 may、must、should等。
