Nuances
为 often implies a sense of purpose or benefit. It is more formal than 给 when meaning "for." When used in passive sentences (被评为), it marks the role or title assigned.
Common Confusion
Don't confuse 为 (wèi) with 给 (gěi). 给 is more direct and common in spoken Chinese for "to give" or "for" in everyday contexts, while 为 is more formal or literary, often used in written or formal speech.
