各种时态的被动语态
被动语态概述
被动语态的概念：它是动词的一种形式，表示主语与谓语之间的执行或被执行关系。主动语态表示主语是谓语动作的执行者，例如：They saw the little boy crying by the river。被动语态表示主语是谓语动作的承受者，例如：The little boy was seen crying by the river。
被动语态的构成
被动语态的.形式是由“助动词be+动词的过去分词”构成。助动词be随着主语的人称、数、时态等的不同而变化。几种常见时态的被动语态形式如下：
1、一般现在时am/is/are +过去分词
例如：Rice is planted in the south of China。
2、一般过去时was/were +过去分词
例如：These trees were planted the year before last。
3、一般将来时will/shall + be +过去分词
例如：A sports meeting will be held next week in our school。
4、现在进行时am/is/are + being +过去分词
例如：Your radio is being repaired now。
5、过去进行时was/were + being +过去分词
When he got there， the problem was being discussed。
6、现在完成时have/has + been +过去分词
His work has been finished。
Has his work been finished？ Yes， it has。 / No， it hasn’t。
7、过去完成时had + been +过去分词
注意：
1、除了be之外的其它系动词如get， stay等也可以和过去分词构成被动语态。例如：Their questions haven’t got answered。
2、含有情态动词的谓语变成被动语态使用“情态动词+ be +过去分词”结构。例如：
More attention should be paid to the old in this country。
This work can’t be done until Mr。 Black comes。
3。含有“be going to”， “be to”等结构的谓语，其被动语态分别用“be going to + be +过去分词”和“be to + be +过去分词”。例如：
The problem is going to be discussed at the next meeting。
All these books are to be taken to the library。
4、被动语态与系表结构的区别：“连系动词+用作表语的过去分词”构成的系表结构，与被动语态的形式完全一样，所以应注意它们的区别。被动语态中的过去分词是动词，多强调动作；系表结构中的过去分词相当于形容词，多强调状态。前者通常可用by引出动作的执行者，而后者则不可以。例如：
The map was changed by someone。（被动结构）
That custom remained unchanged for many centuries。（系表结构）
系表结构中的过去分词通常可被very修饰，被动语态中的过去分词往往要用much修饰。
例如：
He was very excited。（系表结构）
He was much excited by her words。（被动结构）
5。主动形式表被动意义。有些动词的主动形式有被动意味，如open， read， sell， shut， wash， wear， write等。此时句子的主语一般是物。例如：
These books sell well。这些书很畅销。
The door won’t shut。这门关不上。
The clothes wash well。这些衣服很好洗。
