题目内容

20．People in our village threw away a great number of plastic bags last year．（被动语态）
A great number of plastic bagswere thrown away in our village last year．

分析去年村庄里的人们丢了大量的塑料袋．
去年大量的塑料袋被丢在我们村庄．

解答答案：were thrown．原句中的threw得知是一般过去时，改为被动语态的结构是：主语+was/were+过去分词+by+宾语．主动语态的主语变成宾格由by连接，主动语态的宾语A great number of plastic bags改为被动语态所在句的主语，为复数，故选were，throw的过去分词为thrown．故答案是：were thrown．

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．
