面临中考，九年级的学习任务就多了一项复习。要边学习新知识，边进行总结归纳，这样更利于有效的总复习。以下为九年级英语知识点总结：
被动语态
被动语态常用于以下两种情况:
1.不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者;
2.强调动作的承受者。例如:
C.熟练转换
1.将主动语态变被动语态的基本方法为:
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+及物动词的过去分词”，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短语可以省略)。
2.被动语态的一般疑问句是将一个助动词置于主语之前;否定句是在第一个助动词后加not;特殊疑问句的语序为:疑问词+一般疑问句。例如:
Where did they grow vegetables?(改为被动语态)
Where were vegetables grown ?
将主动语态变被动语态应注意几个特殊情况:
1.含双宾语的主动结构变为被动结构时，有两种方法:
①将间接宾语变为主语，直接宾语保持不变;
②将直接宾语变为主语，间接宾语用介词to或for引导。
2.短语动词的被动语态:在变为被动语态时，要将短语动词视为一个整体，其后的介词或副词不能省去。
3.含有复合宾语的主动结构变被动结构时，通常将宾语变为被动句的主语，而宾语补足语就成为主语补足语。注意:省略to的不定式作宾补时，不定式符号to必须补上。
4.不定式的被动结构:动词不定式的被动语态为“to be +过去分词”。
