初中被动语态的常见错误及纠正方法被动语态是初中英语中常见的语法形式，但学生在使用被动语态时，经常会出现一些错误。

以下是初中被动语态的常见错误及纠正方法：错误1：主动变主动有些学生在使用被动语态时会错误地将主动语态变成了被动语态。

例如，“Tom writes a book”（汤姆写了一本书）被错误地译为“a book is written by Tom”（一本书被汤姆写了）。

正确的翻译应该是“a book is written by Tom”（一本书是由汤姆写的）。

要避免这个错误，学生需要清楚理解被动语态的结构特点，即主语+be动词+过去分词。

错误2：被动语态的时态错误有些学生在使用被动语态时会出现时态错误。

例如，“They will clean the classroom”（他们将要打扫教室）被错误地译为“the classroom will be cleaned by them”（教室将被他们打扫）。

正确的翻译应该是“the classroom will be cleaned”（教室将要被打扫）。

被动语态的时态应与主动语态保持一致，只需将助动词和主动语态中的动词一起使用即可。

错误3：被动语态的主语无法确认有些学生在使用被动语态时，无法明确被动的主语。

例如，“The cake was eaten”（蛋糕被吃了），但学生不知道蛋糕被谁吃了。

为了明确主语，学生可以加上“by someone”（由某人）等短语来表达。

例如，“The cake was eaten by someone”（蛋糕被某人吃了）。

纠正方法：1. 学生需要对被动语态的结构特点进行掌握，即主语+be动词+过去分词。

2. 学生应熟悉被动语态的时态运用，与主动语态时态保持一致。

3. 学生在使用被动语态时，需要明确被动的主语，可以加上“by someone”等短语来表达。

通过纠正这些常见错误，学生们可以更准确地运用被动语态，提高英语写作的能力。

“who___ in the mountains for two days”是定语从句，修饰two tourists，two tourists和trap之间是被动关系，该空应用被动语态。

点睛：过去完成时表示过去某一时间或动作以前已经发生或完成了的动作，即“过去的过去”，其表达形式为had done，被动语态的表达形式为had been done。

3． A human case of H7N9 was reported in 2014 when a woman______ to be infected with the bird flu virus. A．confirmed B．had been confirmed C．was confirmed D．have confirmed 【答案】C 【解析】 试题分析：句意：一例人感染H7N9病毒的报告发生在2014年，当时，一名女性被确诊感染了禽流感。Confirm证实，确认，根据was reported in 2014可知，是过去的事情，先行词是2014，定语从句也用一般过去时，排除B、D；woman与confirm是动宾关系，即她是被确诊的，故选C。 考点：考查时态与被动语态
