题目内容
9．Thomas didn't throw the old magazines away yesterday．（改为被动语态）The old magazinesweren'tthrown away yesterday．
分析 托马斯昨天没有丢掉旧杂志．
旧杂志昨天没有被托马斯丢掉．
解答 答案：weren't thrown．原句是一般过去时的否定句，the old magazines是动词throw的承受者，构成被动关系，故用一般过去时的被动语态was/were+过去分词，主语是复数，故were，throw的过去分词是thrown，故答案是weren't thrown．
点评 一般过去时的被动语态was/were+过去分词的呈现，各种类型的被动语态的构成要理解掌握．
