议上讨论。）
动词形式变化规则
现在进行时
am/is/are being+过去分词。例如：The house is being repaired. （房子正在修理中。）
过去进行时
was/were being+过去分词。例如：He was being operated on when we arrived.（我们到达时他正在接受手术。）
情态动词后接完成式时，有时也可以表示虚拟语气，表示与 过去事实相反的假设或愿望。在这种情况下，句子通常使用 倒装语序，即把情态动词放在主语之前。

误用与避免方法探讨
常见误用类型分析
主谓不一致
在被动语态中，主语通常是动作的承受者，谓语应与主语保持一致。然而，有时会出现主 谓不一致的错误，如“The book was wrote by him.”（正确形式应为“The book was written by him.”）
如果不定式前面的名词是对句子的主语的特点进行的说明的时候，使用不定式的主 动语态表示被动含义。
在there be句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重 点在人。
动名词作主语或宾语补足语时
动名词作主语时，谓语动词为单数，在动名词和不定式中，作为介词的宾语是动 名词，动名词的否定直接在其前加否定词，通过代词的宾格或所有格形式给出逻 辑主语。

结构上的错误
总结词
结构上的错误是指句子中的结构不完整或结 构混乱，导致句子意义不清或语法错误。
详细描述
结构上的错误通常是由于句子中的结构不完 整或结构混乱所导致的。例如，“The book was written by him and published in 2019”这句话中，“and”连接了两个 并列的谓语动词“written”和 “published”，但是“and”前没有主语， 因此这个句子存在结构上的错误。
例如，在句子"The book was written by him."中，"was written"是被动语 态的形式，表示"书"是动作"写"的接 受者。
被动语态的分类
根据时态和语态的不同，被动语态可 以分为多种形式。
此外，还有被动语态的虚拟语气形式 等。
例如，现在进行时的被动语态形式为 "am/is/are being done"，过去完成 时的被动语态形式为"had been done"。
04
被动语态的注意事项
使用被动语态的场合
强调动作的承受者
01
当需要强调动作的承受者而不是动作的执行者时，可以使用被

不知道或不需要指出动作执行者
02
在某些情况下，可能不知道或不需要指出动作的执行者，此时
使用被动语态可以避免提及。
