被动语态的标志：被动语态由助动词be+过去分词构成，时态通过be表现出来。
am /is / are +动词的过去分词
was / were +动词的过去分词
His brther washes bwls every day.
结构：S(主语）+am/is /are +过去分词
He sells the mncakes at a lw price.
step2：找出谓语动词,变成结构是 be+dne，sell的过去分词：sld,
step3：原主动句的主语如需要则放在by后面以它的宾格形式出现（注:不需要则可省略)
The mncakes
at a lw price
把原主动句中的宾语变为被动句的主语。
step4： 其它的成分（定语、状语）不变。
