engage in 意为"参与,从事",用于肯定语气中,多表达的是"主动地参与"如 Companies shall engage in business activities within their registered scope of business.(公司应御闭当在登记的经营范围内从事经营活动.)该动词短语一般在使用时与主语之间要加入 "can,will,shall"等辅助词升悉,且多与to连用,构成非谓语动词短语,如,One of the strangest phenomena of life is to engage in a work that will last long after death.(人生吵拆乎最奇异的现象之一就是,你从事的事业在你死后仍将长久存在.)be engaged in 意为 "忙于...",与"be busy doing sth."类似.,被迫忙碌的意味.**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.
