主动语态变被动语态记忆口诀

主动语态变被动语态记忆口诀

一般情况要熟记，

“be+过去分词”常用起，

过去现在只变be,

将来时态更易记，

前面用上will/would 即，

情态动词大家族，

写在其前就完毕，

完成时态不难记，

have/had been + 过去分词，

进行时态要留意，

be being + 过去分词，

特殊情况要心细，

感官、使役to 提起，

一般现、过用be done，be有人称、时、数变。

完成时态have 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,

现在完成进行同，have (has) been doing。

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。

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。

一般现、过用be done, be有人称、时、数变

例：1、主动：The children gave the foreign guests a warm welcome.

被动：The foreign guests were given a warm welcome by the children.

孩子们热烈地欢迎外宾。

2、主动：People regard him as brilliant.

被动：He is regarded as brilliant by people.

人们认为他很有才华。

以上两例都是一般时态用be done的例子，be有人称、时、数变，第三人称foreign friends 是复数，时态一般过去时，所以"be done"就是were given，而People regard him as brilliant一句，被动后的"be done"就变成单数第三人称is regarded的形式了。

被动：
