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

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.

下面就英语中常见的十种基本时态进行阐述,其它的时态都是在这十种时态的基础上结合而成的。
在语法里,时或时态表示行为发生的时间和说话时的关系。一般分为过去式、现在式、将来式,通常也有与表示动作进行或终止的进行式和完成式等体貌一起相连用的情况。

有些语言,没有时态的使用,如分析语的中文,但必要时,仍有时间副词的辅助。也有些语言,如日文,形容词的词形变化能表达出时间上的资讯,有着类似动词的时态性质。还有些语言,如俄文,一个单词就能表现出时态和体貌。
