19、 bike was stolen yesterday.This car is made in American.2.不必要说出动作执行者时,常用.eg.Rome was not built in a day.3.为了突出强调动作的承受者时,常用被动语态.eg.Thousands of beaches are polluted(污染).The passive voice.被动语态被动语态主动语态变为被动语态的步骤主动语态变为被动语态的步骤:1.把原主动句中的宾语转换为被动语态的主语.2.把动词改为被动形式,即“be+过去分词”.注意 be动词要按新的主语的人称和数进行变化,时态要和原来的主动语态的时态保持一致.3.原来主动语态句中的主语,如果需要,就放在by后面以它的宾格形式出现.如果没有必要就可以省略.其他的成分(定语,状语)不变,句式也不能变.
