Question

求过去完成时的被动语态的例句 5句！！！

Answer 1

完成时态have done，被动将been加中间，(过去完成时had done也包括在内)。 　　

1、主动：We have studied English for 3 years and on at the spare-time school. 　　

被动：English has been studied for 3 years by us and on at the spare-time school. have随新主语变为has)我们已经在夜校里断断续续地学了三年英语了。 　　

2、主动：They had produced 100 tractors by the end of last year.被动：100 tractors had been produced by the end of last year. 到去年年底我们已生产出一百台拖拉机。 　　

3、主动：They have set up a power station in their home town. 被动：A power station has been set up in their home town. 他们的家乡建立了一座发电站。

特例：

有两类动词本身应该直接加“ed”，但由于历史习惯，依旧要双写最后一个字母，再加“ed”。以“元音字母+l”非重读结尾的规则动词变过去分词也要双写“l",再加“ed”。

例如cancel→cancelled，dial→dialled。另外还有一些以非重读闭音节结尾的规则动词变过去分词也要双写最后一个辅音字母,再加“ed”。例如：kidnap→kidnapped，worship→worshipped。而上述两种情况在美国一般却直接加“ed”。
