一般现在时：疑问句 (A1)

用 I, you, we, they 提问时，句子开头用 Do + 动词原形。

疑问句：Do

• Do you speak English?
• Do they live here?
• Not "Are you live here?" — say "Do you live here?". 问一个动作的时候，句子开头用 Do，不是 'Are'。
• 试一试: ___ you live here? (Do / Does / Are) 答案: Do — 用 you 的时候，问句开头用 Do，后面接原形动词：Do you live here?

疑问句：Does

用 he, she, it 提问时，句子开头用 Does + 动词原形。

• Does he work here?
• Does she like coffee?
• Not "Does he works here?" — say "Does he work here?". Does 已经带了 -s，动词要变回原形。
• 试一试: ___ he work here? (Does / Do / Is) 答案: Does — 用 he 的时候，问句开头用 Does（Do 是给 I/you/we/they 用的）：Does he work here?
