They heard him sing songs in the room last night. →He was heard to sing songs in the room last night. 注：究竟有没有to, 其实有个巧门： “使役”动词前有be，则有to；没be，则没to。 My mother gives Lily a pen. →Lily is given a pen by my mother. →A pen is given to Lily by my mother. 间接宾语 直接宾语 如： The flower smells nice.　 The cake tastes delicious.　 The watch looks beautiful. 如： Great changes were taken place in China.(×) →Great changes took place in China.(√) 1. 因为景色优美，白水寨每天都有人来参观。 2017增城区一模
