查字典中考网整理了关于2020年中考英语知识点之主动语态变被动语态常见错误，希望对同学们有所帮助，仅供参考。
（1）误用语态。比如：
Children often sing this song.
孩子们经常唱这首歌。
错误：This song was often sung bychildren.
正确：This song is often sungby children.
解析：由主动语态变为被动语态，只是谓语动词从主动式到被动式的转变，时态不能改变，即主动句用什么时态，变为被动句时还要用同一种时态。
（2）误用句子种类。比如：
Do they make those bikes in their workshop?
他们在车间生产自行车吗?
错误：Thoseb ikes are made in their workshop.
正确：Are those bikes made in their workshop?
解析：主动语态变被动语态，句子的种类（陈述句、否定句、疑问句）不能改变。如果主动句是一般疑问句，变为被动句时，也要用一般疑问句形式。
（3）错选宾语。比如：
The teacher gave some advice to the student.
老师给学生一些意见。
错误：The student was given some advice to by the teacher.
正确：Some advice was given to the student by the teacher.
解析：the student是介词to 的宾语。变为被动语态时不能作为句子的主语，应把紧跟在谓语后的宾语（some advice）变为句子的主语。
（4）主谓不一致。比如：
He usually watches TV in the evening.
他通常在晚上看电视。
错误：TVwas usually watched inthe evening.
正确：TVis usually watchedin the evening.
解析：被语态的谓语动词结构be+p.p.中的be应和其主语（即原来主动语态中的宾语）在人称和数上保持一致。
