主动语态：主语为施力者（执行者）
被动语态：主语为受力者（承受者）
被动语态(passive vice)是动词的一种特殊形式，用以说明主语与谓语动词之间的关系。一般来说，只有需要动作对象的及物动词才有被动语态。汉语往往用"被""受""给"等被动词来表示被动意义 。
隆重登场：My name is “by”. I am als very imprtant in passive vice. If yu frget me , peple wn’t knw wh has dne that thing. S, in Chinese, I am called “被”.
被动语态的构成结构：be+ 及物动词的过去分词
主动：We clean the classrm every day.被动：The classrm is cleaned by us every day.
在不同的时态中，只需要变化be 动词的形式，过去分词部分不发生变化。疑问式和否定式的变化也如此。
主动：They plant flwers every year.被动：Flwers are planted by them every year.
主动：The Brwns planted flwers last year.被动：Flwers were planted by the Brwns last year.
主动：The Brwns will plant flwers next year.被动：Flwers will be planted by the Brwns next year.
情态助动词也有它的被动语态形式哦！！！
主动：Parents shuld allw kids t watch TV n weekends.被动：Kids shuld be allwed t watch TV n weekends by parents.
主动：We must hand in hmewrk n time.被动：Hmewrk must be handed in n time.
部分动词在主动语态中后接宾语补足语的时候不加t，然而改成被动语态时应加上t。它们是：let make see hear ntice watch
主动：The bss made the wrkers wrk 12 hurs a day.被动：The wrkers were made t wrk 12 hurs a day by the bss.
主动：We ften hear the blind by practice the pian.被动：The blind by is ften heard t practice the pian.
