简短回答 (A1)

如果问句以 Do 或 Does 开头，就用 do 或 does 回答，不用主要动词。

Do / Does 问句

Do you like it? → Yes, I do.
Does she work here? → Yes, she does.
Do they play? → Yes, they do.
Not "Do you like it? → Yes, I like." — say "Do you like it? → Yes, I do.". 用问句里的词（do）来回答，不是主要动词。
试一试: Does Ethan work at the community center? → Yes, he ___. (does / do / works) 答案: does — 问句用了 Does（he/she/it），回答要对应：Yes, he does（不是 "do"，也不是主要动词）。

如果问句以 Am, Is, 或 Are 开头，就用 am, is, 或 are 回答。

Are you happy? → Yes, I am.
Is she ready? → Yes, she is.
Are they here? → Yes, they are.
Not "Is she ready? → Yes, she ready." — say "Is she ready? → Yes, she is.". 用问句里的词（is）来回答，不要漏掉。
试一试: Are you ready? → Yes, I ___. (am / do / are) 答案: am — 问句用了 Are，而 I 对应的形式是 am：Yes, I am（不是 "do"，也不是 "are"）。

如果问句以 Can 开头，就用 can 回答。

Can you swim? → Yes, I can.
Can she drive? → Yes, she can.
Can they help? → Yes, they can.
Not "Can you swim? → Yes, I swim." — say "Can you swim? → Yes, I can.". 用 can 回答，不是主要动词。
试一试: Can Hiroshi fix it? → Yes, he ___. (can / does / fixes) 答案: can — 问句用了 Can，所以回答是 can：Yes, he can（不是 "does"，也不是主要动词）。

要说不，用简短词 + n't：don't / doesn't, isn't / aren't, can't。用 I 的时候，要说 I'm not。

Do they play? → No, they don't.
Does she work here? → No, she doesn't.
Is she ready? → No, she isn't.
Are they here? → No, they aren't.
Are you tired? → No, I'm not.
Can he swim? → No, he can't.
Not "Can she drive? → No, she doesn't." — say "Can she drive? → No, she can't.". 否定回答仍然要对应问句，Can → can't。
试一试: Can Mateo come tonight? → No, he ___. (can't / doesn't / isn't) 答案: can't — 问句用了 Can，否定回答也要对应：No, he can't（不是 "doesn't" 或 "isn't"）。
试一试: Are you hungry? → No, I'm ___. (not / aren't / don't) 答案: not — 问句用了 Are you，所以回答要换成 I。用 I 的否定回答是 I'm not（不是 "aren't"，也不是 "don't"）。

问句用哪个词开头，回答就用哪个词。Do / Does → do 或 does。Am / Is / Are → am、is 或 are。Can → can。

Do you like it? → Yes, I do.
Is she at home? → Yes, she is.
Can you help me? → Yes, I can.
Not "Can you help me? → Yes, I help." — say "Can you help me? → Yes, I can.". 问句以 Can 开头，所以回答也用 can，不用主要动词。
试一试: Yasmin: Are the children at school? Liam: Yes, they ___. 补全 Liam 说的话。 (do / are / can) 答案: are — 问句以 Are 开头，所以回答也用 are。Do 回答以 Do 开头的问句，can 回答以 Can 开头的问句。
