区别一：affect 与 effect 均可表示“影响”,其区别是：前者是动词(及物),主要指一时的影响,着重影响的动作,可指一般意义的影响(不分好坏),也可指不良影响；后者是名词(可数或不可数)可数或不可数,两者的关系大致为：affect＝have an effect on.如：To affect a policy is to have an effect on it.影响一项政策就是对该政策具有一种影响.The news did not affect her at all.＝The news had no effect on her at all.这条消息对她没有一点影响.注：effect 有时虽用作动词(及物),但不表示“影响”,而表示“实现”或“产生”等.如：They effected their escape in the middle of the night.He effected great changes in the company.他使公司发生了巨大的变化.
区别二：influence 表示“影响”,主要指对行为、性格、观点等产生间接的或潜移默化的影响.可用作动词”(及物)或名词(通常不可数,但有时可连用不定冠词).如：What you read influences your thinking.你读的东西对你的思想有影响.Television has a strong influence on people.电视对人有很大的影响.It’s clear that her painting has been influenced by Picasso.她的画显然受了毕加索的影响.
