Teetotalism refers to either the practice of or the promotion of complete abstinence from alcoholic beverages. A person who practices (and possibly advocates) teetotalism is called a teetotaler or is simply said to be teetotal.

禁酒主义（teetotalism）指践行或推广禁止饮用酒精饮料的做法，实践（或提倡）禁酒主义的人就叫做teetotaler（滴酒不沾的人，禁酒人士）。

Some common reasons for choosing to be a teetotaler are religious, health, family, fear of gastric or social reasons, and, sometimes, as simply a matter of taste or preference. When at drinking establishments, teetotallers either abstain from drinking or consume non-alcoholic beverages such as tea, coffee, water, juice, soft drinks and mocktails.

选择做禁酒人士常见的原因多与宗教、健康、家庭、肠胃以及社会问题有关，有时也可能只是因为口味的原因选择不喝酒。在一些饮酒的场合，禁酒人士或者避免参与，或者就选择一些不含酒精的饮料，比如茶、咖啡、白水、果汁、软饮以及不含酒精的鸡尾酒等。
