1.consult的基本意思是为了作出一项决定、取得一项解决办法而进行对话或讨论。可以是单向的,即“请教”“咨询”; 也可以是双向的,即“商议”“商量”。无论是“咨询”还是“商量”,双方地位都是平等的。引申可以表示向书本咨询,即“翻阅”“查考”资料,也可以表示向自己咨询,即“考虑”“顾及”。
2.consult可用作不及物动词,也可用作及物动词。作“请教”解时多接人作宾语; 作“翻阅”解时常接书、词典、地图等作宾语; 作“考虑”解时其宾语多为抽象名词。表示“与…商量”可接介词with; 表示请教或商议的一般内容可接介词about,重大或特殊内容则接介词on; 而接介词for时则表示“为…当顾问”。
3.consult极少用于被动结构。
