2. 或者只需强调动作的承受者时,要用被动语态.被动语态结构：be + 过去分词(PP) + (by …)在改写中应注意：1.把原来的宾语提到前面作被动语态的主语;2.把动词变成“be + 过去分词”;3.主动语态中的主语变为介词by的宾语.时态被动语态结构一般现在时 am/is/are done 一般过去时 was/were done 现在进行时 am/is/are being done 过去进行时 was/were being done 一般将来时 shall/will/be going to be done 过去将来时 Would be done现在完成时 have/has been done 过去完成时 had been done Eg.Some people attacked the towers.
