形式为主动，意义为被动。(中考难点)🍏

3.形容词 cheap, dangerous, important, comfortable, interesting等接不定式做状语时，不定式的主动形式表被动意义。

口诀🍏
一般现在时、一般过去时用be +及物动词的.过去分词，be有人称、时、数变。
完成时态have(has)done，被动将been加中间。
一般将来shall(will)do，被动变do为be done。
将来进行无被动，shall(will)be doing。
现在完成时，被动 have(has)been done。
现、过进行be doing，被动be加being done。
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。
