一般过去时的被动语态的句式结构
2. 一般过去时的被动语态的基本用法
表示过去某一具体时间发生的动作，且句子的主语是谓语动词动作的承受者

3. 含双宾语和复合宾语的主动句变为被动语态的方法
①含有双宾语的主动句变为被动语态时，通常把指 “人”的间接宾语变为主语，而指“物”的直接宾语则不变。
He gave me a bk yesterday.
→ I was given a bk (by him) yesterday.
② 如果要把指“物”的直接宾语变为主语，则在间接宾语前加t或fr。
I brught him sme fd.
→ Sme fd was brught t him (by me).
③含有复合宾语的主动句变为被动语态时，要将其中的宾语变成主语，宾语补足语不变。
Jim asked Tm t g fr a walk.
→ Tm was asked (by Jim) t g fr a walk.
④ 如果宾语补足语是不带t的动词不定式，主动语态变成被动语态时要加上不定式符号 t。
We ften heard Kate sing in the rm.
→ Kate was ften heard t sing in the rm (by us).
