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"。
