人教高中英语必修2Unit 3 Computers语法知识总结现在完成时的被动语态本单元学习现在完成时被动语态，同学们看下面两道题：1. I like these English songs and they ______ many times on the radio.A. taughtB. have taughtC. are taughtD. have been taught2. More and more attention ______ to wildlife protection in recent years but still more needs to be done.A. has paidB. will have been paidC. is being paidD. has been paid解析： 1. D. they 指these English songs 和teach之间存在被动关系，可排除A、B。
根据many times 可知应该与现在完成时连用。
2. D. 主语attention 与pay 之间是逻辑上的动宾关系，故要用被动语态；时间状语in recent years 常与现在完成时连用，故用现在完成时的被动语态。
该知识点总结如下：当根据题意判断为现在完成时，并且主语与谓语动词之间是动宾关系（被动关系），我们需要使用现在完成时的被动语态。

高一英语必修二unit 3 语法 现在完成时的被动语态
现在完成时的被动语态一、结构：have / has been done二、用法：1）表示到现在为止已经完成的某个被动动作。
The new museum has already been completed(完成) recently.2）表示某个被动动作在说话之前发生，但对现在造成影响Your son has been sent to the hospital, so you needn’t worry too much.3）表示过去已经开始，持续到现在，也许还会持续下去的某个被动动作，往往与表示一段时间的状语连用（如for，since）等，或者so far, now, today, this week 等连用。
Computers have been widely used since the 1970s.三、副词的位置：often, usually, always, never, hardly, seldom 等副词置于have/ has 与been中间Such a man has hardly been believed.四、并不是所有动词都有被动语态。

但短语动词是一个不可分割的整体，变为被动语态时，不可丢掉构成短语的介词或副词。

Why do we use passive sentences?
A pair of active sentence and passsive sentence convey a similar meaning, but they are slightly different. Passive sentences are default and are used often. We use passive sentences when 1. the doer of an action is not necessarily mentioned. 2. the doer of an action is unknown. 3. the doer of an action is not important 4. the doer of an action is preferred not named

Computers have been widely used since the 1970s.三、副词的位置：often, usually, always, never, hardly, seldom 等副词置于have/ has 与been中间Such a man has hardly been believed.四、并不是所有动词都有被动语态。
只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place（发生）, die, appear（出现）, disappear（消失）, remain, last（持续）, sit , break out（爆发）, come true（实现）, belong to，consist of，run out(耗尽)等但许多不及物动词加介词或副词构成的短语动词，相当于及物动词，也可以有被动语态。
但短语动词是一个不可分割的整体，变为被动语态时，不可丢掉构成短语的介词或副词。

People believe that he is an honest boy. →方法1) 把宾语从句里的主语变成被动句的主语，同时把宾语从句中的谓语变成不定式短语。
The boy is believed to be an honest one.It is believed that he is an honest boy.方法2) 用先行的it作形式主语，把宾语从句变成后置的主语从句；We all think that we could win the game.We are thought to win the game.It is thought that we could win the game.四、主动形式表示被动意思的动词1) 感官动词: look, sound, smell, taste, feel●How sweet the music sounds.●The food doesn’t look as good as it tastes.2) 主语是物，谓语是表示主语特征或属性的动词。
