Most middle school students play football._2. China produce tea._3. My mother plant a tree._变成主动句.Compouters are used by many people._.英语中有两种语态，即_和_.主动语态用在主动句中，被动语态用在被动句中。主动语态表示主语是动作的_,被动语态表示主语是动作的_.实际上被动句的主语是由主动句的宾语转变而来的，因此这个谓语动词必须是_动词。被动语态中的谓语动词的执行者可由_引出，意为_，常常置于句末。如果不强调动作的执行者时，可省略。Many people speak Chinese._语态，译为_Chinese is spoken by many people. _语态，译为_。4.Discussion and presentations.
