动词的被动语态

　　一般现在时、一般过去时用be +及物动词的.过去分词，be有人称、时、数变。

　　完成时态have(has)done，被动将been加中间。

　　一般将来shall(will)do，被动变do为be done。

　　将来进行无被动，shall(will)be doing。

　　现在完成时，have(has)been done。

　　现、过进行be doing，被动be加being done。

　　情、助、有、是妥安排，一律随新主语变。

　　不v合并图册(2张)

　　否定助后加not，疑问一助置主前。

　　主语恰是疑问词，直陈语序主在前。

　　一般情助加be done，双宾多将间宾变。

　　复合宾语宾变主，宾补、主补相应变。

　　第二句“be有人称、时、数变”即be有人称、时态和单、复数的变化。“情助”是指情态动词和助动词“must，may，can，shall，will”等一律随新主语(多是主动句中的宾语)来变化。“疑问一助置主前”是说有两个助动词的话，应把主语放在第一助动词之后或把第一助动词置于主语之前。下面详细举例说明之：
