问题：请问专家老师:reduce后动词用什么形式?专家老师,我门书本上 
专家,我门书本上有句: This reduces pollution and waste going into the environment.这是否意味着reduce后动词用ing 形式? 如果不是那么 reduce  后究竟跟什么形式? 谢谢了!
回答：This reduces pollution and waste going into the environment.这句话 reduce是谓语动词,pollution and waste 是宾语,going into the environment是非谓语动词做pollution and waste 的定语.
reduce的用法be reduced to或be reduced by
