求英语被动语态公式
要求把前后转换都写起 如be+doing=be+being+done

一般现在时:be done 一般过去时:be(过去式)done 一般将来时:will be done 或是 be going to be done 现在完成时:has been done 过去完成时:had been done 现在进行时 is\am\are+being done 过去进行时 was\were+being done 情态动词:情态动词(must can could may maight shall should 等) +be done 不定式:to be done 如果被动语态涉及到过去,只把be[am is变was,are 变 were ]动词变成相应的过去式 情、助、有、是妥安排,一律随新主语变.否定助后加not,疑问一助置主前.主语恰是疑问词,直陈语序主在前.一般情助加be done,双宾多将间宾变.复合宾语宾变主,宾补、主补相应变.
