一般过去时被动语态是英语中的一种重要语法结构，表示过去某个时间主语所承受的动作。其结构为was/were加上过去分词。例如，肯定句中，“Many trees were planted by us last year.”表示“去年我们种了许多树”。否定句形式为在be动词后加not，如“Many trees were not planted by us last year.”，意为“去年我们没有种很多树”。一般疑问句则是将be动词提前，如“Were many trees planted by us last year?”，回答可以是“Yes, they were.”或“No, they weren’t.”。此外，还提供了多个例句，如“The house was built by them last year.”、“His sister was taken good care of by him yesterday.”等，进一步展示了这种语态的用法。同时，还包含了与主动语态的转换练习，以及中考题型的实战演练，如“The letter __last week，and it didn’t __yesterday.”的正确答案是B. was posted, arrive，表示“是上周寄出的，昨天没有到。”
