不免……

不免…… means "cannot help but; inevitably" and follows the frame 不免 A. Use it when the sentence needs to say a feeling or situation naturally cannot be avoided. Pay attention to register: many patterns in this group are formal, evaluative, or rhetorical, so they are stronger than everyday words. Do not choose a pattern only because the translation looks close; check whether the sentence is evaluation, sufficiency, inevitability, suggestion, or rhetorical affirmation/denial. Common mistakes include dropping fixed characters such as 于, 是, 不, 能, 非, confusing 难免, 不由得, 未免, or using a rhetorical pattern in a neutral statement.
