用"还是"提问

**What it means:** 还是 creates a choice question — it presents exactly two options and asks the listener to select one. This is different from an open-ended question.

**Structure:** A + 还是 + B？ - A and B can be nouns: 苹果还是橙子？ - A and B can be verb phrases: 你去学校还是待在家？ - A and B can be full clauses sharing the same subject.

**When to use:** Use 还是 when you have two clear alternatives and want the listener to choose one. It implies that one or the other must be true.

**When NOT to use:** - NEVER add 吗 to a 还是 question: 你去还是不去吗？is WRONG. - Do NOT use 还是 in a statement (use 或者 instead): 你可以喝茶或者咖啡。(statement) vs. 你喝茶还是咖啡？(question)

**Common mistake — 还是 vs 或者:** - 还是: questions only, forces a choice between two things. - 或者: statements only, means 'or' when listing options without asking. - WRONG in a statement: 你喝茶还是咖啡就好。 → use 或者 - WRONG in a question: 你喝茶或者咖啡？ → use 还是

**Answering a 还是 question:** Choose one option — do NOT answer with 是 or 不是.
