"Tôi bị cấm uống rượu."

Translation: I am prohibited from drinking alcohol.

[Dan553966]

Why is "forbidden" wrong?

[StewartMM]

Yes, I think that is actually better in this case.

[CBlondie]

Why is "I am being prohibited from drinking wine" wrong when the hint given for Bị is 'being'

[Huy_Ngo]

"Bị" is Vietnamese word used to mark passive voice. It is the equivalence to English "to be" in this case.

[vngdhuyen]

as Huy has said, bị indicates the passive voice. the difference between their translation and yours is mostly the progressive tense used in your answer.

• "I am prohibited" vs "I am being prohibited".
• "tôi bị cấm" vs "tôi đang bị cấm".

[alexobviously]

forbidden is better than prohibited
