英语被动语态：Did Li Lei repair the door yesterday.
问题描述：
英语被动语态：Did Li Lei repair the door yesterday.
答
分析被动语态要注意两点：一是该句的主语和宾语；二是该句的时态。
一、本句中，主语为Li Lei, 宾语为the door。被动语态的结构是原句的宾语变为主语，主语变为by sb. 中的人。
二、此句为一般过去式。一般过去式的被动语态为was/were done. 该句话
因此原句变被动语态为Was the door repaired by Li Lei yesterday?
希望能帮到你！
答
此句的陈述句为 Li Lei repaired the door yesterday.，但是Li Lei 是第三人称单数，所以用did 做助动词，改为疑问句是，助动词提前，改为被动句时为：Did the door repaired by Li Lei yesterday？
答
Was the door repaired by Li Lei yesterday.?
