6、are encouraged,3、接动词原形做宾补的动词变被动语态,使役动词(let,have,make等)或感官动词(see,hear,watch,等)在主动语态中后面接的动词不定式省略to，改为被动语态时一定要补上to。(记忆口诀：“使感动词”真奇怪，to在句中像妖怪，主动语态to走开，被动语态to回来。”)I heard him sing in the next room.-He sing in the next room.They made us do all kinds of work.-We do all kinds of work.注：当使用see/hear/watch sb d
