1、 初中被动语态语法讲解课堂教案 2 初中被动语态语法讲解(一)语 态 分 类 英语动词有两种语态.，主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。如：They will build a new bridge over the river.()A new bridge will be built over the river.()英语用：助动词 be+及物动词的过去分词构成。(二)被动语态的时态、人称和数的变化 主要表达在 be 的变化上，动词的过去分词不变。列表如下：一般现在时：+done 一般过去时：+done 一般将来时：+done 过去将来时：+do
2、ne 现在进行时：am/is/are+being+done 过去进行时：was/were+being+done 现在完成时：+done 过去完成时：had+been+done 将来完成时：shall/will+have been+done 过去将来完成时：should/would+have been+done 注被动语态没有将来进行时和过去将来进行时。3(三)常见的八种时态中的被动语态 1.一般现在时：(1)People grow rice in the south of the country.Rice in the south of the country.(2)The school do
