现在完成时1.概念:过去发生或已经完成的动作对现在造成的影响或结果,或从过去已经开始,持续到现在的动作或状态。
2.时间状语:recently, lately, since…for…,in the past few years, etc.3.基本结构:have/has + done4.否定形式:have/has + not +done.5.一般疑问句:have或has提前对于初接触现在完成时的人来说,往往会产生一种茫然,因为它似乎与一般过去时相似。
那就是,这两种时态描述的动作都始于过去。
其实不然,现在完成时主要表示,发生在过去的动作延续到现在刚刚完成、或许还要延续;侧重于这个动作对现在带来的结果、产生的影响、积累的总和等等。
而一般过去时则只不过是表示动作发生在过去的什么时候。
弄清了这一区别,就很容易理解现在完成时了。
它主要适用于下面的几种情况:1)表示截止现在业已完成的动作By now, I have collected all the data that I need .到现在为止,我已收集到了我所需的全部资料。
She has read 150 pages today .她今天已看了150页。
2)表示发生在过去而对现在产生影响、带来结果的动作Have you had your dinner? 你吃晚饭了吗?3)表示过去发生的动作持续到现在,并可能还要延续It has been five years since he joined the army .他参军五年了。
1)一个句子应该用什么时态只能取决于它需要表达的意思,以及它所处的语言环境。
例如:He speaks English .(一般现在时,说明动作发生的经常性。
)He spoke English when he was in New Zealand .(一般过去时,说明动作发生的时间。
)He is speaking English.(现在进行时,说明动作正在进行。

初中被动语态全解语态表示主语和谓语的关系,英语的语态是通过动词形式的变化表现出来的。
英语中有两种语态:主动语态和被动语态。
如果主语是动作的执行者,或者是说动作是由主语完成的,要用主动语态,如:We speak Chinese in China.在中国我们说汉语,speak的动作是由主语we来执行的。
如果主语是动作的承受者,或者是说动作不是由主语而是由其他人完成的,则用被动语态,如:Chinese is spoken by us in China.在中国汉语被我们说,Chinese是动词speak的承受者。
一.被动语态的时态:be +动词的过去分词1.一般现在时的被动语态结构:is /am/are +及物动词的过去分词+其它+by sb.Football (play)all over the world。

现在完成时的主动与被动的句子
现在完成时是英语中的一种时态,用于表示过去发生的动作或事件对现在造成的影响或状态。
它可以用于主动语态和被动语态。
下面我将为你提供主动和被动语态的现在完成时句子示例:
**主动语态(Active Voice):**
1. I have finished my homework.(我已经完成作业。
)
2. She has written three books.(她已经写了三本书。
)
3. They have eaten dinner.(他们已经吃过晚饭。
)
**被动语态(Passive Voice):**
1. My homework has been finished.(我的作业已经被完成。
)
2. Three books have been written by her.(三本书已经被她写过。
)
3. Dinner has been eaten by them.(晚饭已经被他们吃过。
)
请注意,被动语态中的句子结构是由助动词"have been"(根据主语的人称和数变化)和过去分词构成的。
在被动语态中,动作的执行者变成了句子的主语之外的部分,而受动作影响的对象成为了主语。
英语(十八)Book2 Unit 3 语法现在完成时的被动语态构成:have/has been done 第三人称单数用has,第三人称复数以及其余人称用have。
否定式是在have/has 后加not,也可缩写成haven’t/hasn’t;构成疑问句时,附加问句借助于have/has。
特殊疑问句式:疑问词+have/has+主语+been+及物动词的过去分词。
1.表示发生在过去的动作对现在产生的影响或结果,这个动作是被动的。
This novel has been translated into several languages.2.还可以表示在过去发生的,已知延续到现在的并可能持续延续下去的被动动作或状态。
常与for或since引导的时间状语连用,或用于“How long…?”句型中。
The machine has been used for 3 years.3.用在时间或条件状语从句中,表示将来某时已完成的动作,即用现在完成时态的被动语态代替将来完成时的被动语态。
You can go home as soon as your homework has been finished.4.注意1)现在完成时的被动语态的两个助动词:have/has和been 缺一不可。
2)注意与一般过去时被动语态的区别。
一般过去时的被动语态表示一个被动的动作发生在过去,其结果对现在没有影响;而现在完成时的被动语态的动作或状态尽管发生在过去,但侧重说明该动作或状态对想在造成的影响或结果。
The machine has been repaired.(说明动作发生在过去,对现在有影响,“修好了”) The machine was repaired yesterday.(只说明动作发生在昨天)3)不可与确定的表过去或将来的时间状语连用(如yesterday,three days ago,in 1970,in 2050等),但可与不确定的时间状语连用(如already,yet,just,often,recently,in the past few years等)They have been punished recently.4)有些动词像finish,buy,start,begin,return,join,marry,open,die等,表示的动作很短暂,我们称之为短暂性动词或非延续性动词。
