过去进行时构成：was/were + being + 动词的过去分词

带有情态动词的被动语态构成：情态动词 + be + 动词的过去分词例如：Can this walkman be repaired here?

主动语态改为被动语态的步骤：

①主动语态中的宾语变为被动语态句中的主语；

②主动语态句中的动词改为相应的被动语态；

③主动语态句中的主语变为被动语态句中by的宾语。

主动语态句中的谓语动词带有双宾语，即直接宾语和间接宾语时，转换方法有两种：

①把间接宾语转化为主语，保留直接宾语

②把直接宾语转化为主语，保留间接宾语。此时，一般需在间接宾语前加适当的介词（通常是介词for或to)。

在短语see sb. dosth. 中，动词see后跟不带to的不定式作宾补。改为被动语态时要加上to。用于这一结构的谓语动词一般是表示知觉的动词如see, hear,watch,find等，以及使役动词make, let等。
