英语中的被动时态
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 ben finished? Yes，it has./No，it hasn’t.
7、过去完成时had+been+过去分词
扩展资料
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 oldin this country.
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.
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)
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。
Our classroom is cleaned everyday.
I am asked to study hard.
Knives are used for cutting things.
