1、engage in 是主动语态:从事,忙于,表达时须有in才能加对象。engage in多用于肯定语气中,多表达的是"主动地参与",该动词短语一般在使用时与主语之间要加入“can,will”等辅助词,且多与to连用,构成非谓语动词短语。
例如:engage in politics 从事于政治
2、be engaged (in)是被动语态:忙着,做着,参加,有时可无in。与"be busy doing sth."类似,被迫忙碌的意味。be engage in 的否定结构是"can/do/does...not be engaged in",这里的be engaged in则取"参与、从事"的意思。
例如:be engaged in business 从事商业活动
