3、ball is played by many people.一、被动语态的构成8【教学过程】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

5、 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1【教学过程】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
