一、重点语法：

被动语态

　①英语有两种语态：

主动语态和被动语态　

　　主动语态表示主语是动作的执行者

　　被动语态表示主语是动作的承受者　

Wevisitedthatfactorylastsummer主动语态

主语谓语宾语状语

Thatfactorywasvisitedbyuslastsummer被动语态

主语谓语宾语状语

②被动语态的构成

　　由“助动词be＋及物动词的过去分词”构成

　　助动词be有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。

③被动语态的特殊用法

1.有些动词带有两个宾语，即直接宾语和间接宾语，变被动语态时，可把其中一个宾语变成主语，另一个留在被动结构谓语后面。

需要注意的是：

若把直接宾语变成被动语态的主语，需要在间接宾语之间加上介词“to”。

eg.Heoftentellsusinterestingstories.（主动语态）

（被动语态）

▲常带双宾语的词有：

tell,show,lend,pass等。

2.在主动语态中，某些动词之后带有复合宾语，即宾语和宾语补足语，这个复合宾语由动词不定式来充当，to被省略，但在被动语态中，这个to还要还原。

eg.Ioftenhearhersingthispopularsong.（主动语态）

Sheisoftenheardtosingthispopularsong.（被动语态）

▲有这种用法的常用动词有：

make,let,see,hear,watch,feel,notice等。
