3. affect
vt. 影响;侵袭;相当于;使感动;激起(悲伤、愤怒等情绪)
易混辨析:
affect/effect/influence
affect vt.表示“影响,(病)侵袭”,多指不好的影响。当affect的宾语是人时,它表示引起心智或感情上的影响,即“使感动”。
effect 表示“影响”时,是名词,指由于某种原因直接产生的结果,常用短语为:have an effect on对…有影响;in effect正在实行;实际上;side effect副作用;take effect开始实行;开始生效;without effect没有效果;come into effect生效;实施;bring/carry sth. into effect使…生效;be of no effect 无效果。
influence多指对人的思想、观念、心理情绪等内在的东西产生潜移默化的影响,或对人的决定、行为等造成某种程度的影响。
