题目内容
8.Kike returned the story-books to the library on time.(改为被动语态)The story-bookswere returned returned to the library on timeby Mike.
分析 麦克准时将故事书还给了图书馆.
故事书由麦克准时还给了图书馆.
解答 答案:were returned,by.原句是一般过去时,所以采用一般过去时的被动语态结构:was/were+动词的过去分词,主语是the story-books复数,故用were,return的过去分词returned.主动语态的主语变成宾格由by连接,所以答案为:were returned,by.
点评 此题要求把主动语态变为被动语态,做这类题时,首先由原句的谓语确定采用哪种被动语态结构,再看主语,二者结合即可得出答案.
