语态是动词的一种形式，表示句子中主语和谓语动词的关系。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。只有及物动词才能用于被动语态。

如果是不用物动词，其过去分词应带有相应的介词。例如：

许多人都踢足球。

Many people play football. = Football is played by many people.

一、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。如果需要强调动作或行为的执行者时，在其后接“by...”，意为“被…”

主动语态变被动语态的方法

1.将主动语态的宾语作被动语态的主语

2.谓语动词变为“be+过去分词”，并通过be的变化来表达出不同的时态

3.主动语态的主语变为介词by的宾语，组成介词短语放在被动结构中的谓语动词之后。（有时by短语可省略）

为取胜更清晰、更深刻地理解被动语态的含义，可以将主动语态和被动语态的句子结构进行比较。

主动语态：主语+ 谓语动词 + 宾语 + 其他成分

被动语态：主语+ be +过去分词 + by +宾语 +其他成分

如： Many people speak English.

被动语态 English is spoken by many people.

被动语态中by短语的省略

被动语态中的“by+宾语”表示及物动词所表示动作的执行者。但是在遇到以下情况时，表示动作执行者的by短语常常被省略。

1.动作执行者不确定时 Many people are killed in traffic accidents every year.

2.不必表明动作执行者时 These trees were planted last year.

3.动作执行者为一般大众时 Both English and Spanish are spoken in this area.

4.下面这些动词短语本身已经是被动形式，不需要再加by短语

be interested in对…感兴趣 be made of/from由…制成

be covered with用…覆盖 be surprised at 对…感到惊奇

被动语态的基本用法

*需要强调动作的承受者时

Water is needed very much by the crops here.

*不知道或没必要指出动作的执行者时

Sandy was invited to a party after school.

*当说话人需要强调客观时

It is said that the temperature tomorrow will be fine.
