Hey, guys. I'm Alex. Thanks for clicking, and welcome to this lesson on short answers
with "do" and "have." This is an expansion on a previous lesson on EngVid. So if you
want more information about short answers with "do" and "have," you can check out the
video linked to this video.
A common mistake that students sometimes make when they're learning English is they don't
know when to use "have" and when to use "do" when they have a short answer. So this is
short answers as in "yes" or "no" questions.
For example, the first question I have on the board is, "Do you have a car?"
"Do you have a car?" So we have two verbs here. We have the main verb, which is "have."
This is the main verb. And we have the auxiliary verb, which is "do."
Okay, first rule about short answers is when you give a short answer, pay attention to
the first verb in a "yes/no" question. Here, the first verb is "do." Now, I know you see
the main verb "have." You think, "Do you have a car?" You might think, "Yes, I have." Incorrect.
So what you have to do is pay attention to that first verb. So if you have a "yes/no"
question, always listen to the first verb. It's "Do you?" "Yes, I do." "No, I don't."
If it's "have you," then it's a little different. We'll get to that in a moment.
Okay, "Do you have a car?" The correct answer, "Yes, I do." "No, I don't." Or, "Yes, I have."
"No, I haven't." Should be clear now. It's "Yes, I do." Or, "No, I don't." Not, "Yes,
I have." Or, "No, I haven't."
Now, what tense, what grammar tense is this question in? Present perfect? No. Past simple?
No. No. Yes, exactly. "You." You're correct. That is in present simple. Okay?
So when you have a question in present simple or past simple -- and remember, the past of
"do" is "did." Okay? So, "Did you have a nice time," for example, the rule is the same.
"Yes, I did." Or, "No, I didn't." So present simple questions, "yes/no" questions, "Do
you have?" Okay? Or, "Do you like?" It doesn't matter what this verb is. Focus on the "do"
verb.
Here, I think the answer is obvious already, but let's go through it. "Have you read the
Harry Potter books?" Now, this question, what tense is it? Correct. Present perfect. Okay?
So present perfect, as you might know, has the auxiliary verb "have" and the main verb,
which is a past participle. So what is the past participle here? It is "read." Okay?
So here, you have a past participle, which we use with the present perfect, and here
we have "have," which is the auxiliary verb.
"Have," which is the auxiliary verb. Now, remember what I said. In "yes/no" questions,
you always focus on the auxiliary verb for the response. So here, you have two possibilities,
"Yes, I do." "No, I don't." Or, "Yes, I have." "No, I haven't." If you have been paying attention,
then you know the answer is, "Yes, I have." Or, "No, I haven't." Okay? So this is the
correct response.
"Have you read the Harry Potter books?" "Yes, I have." Or, "No, I haven't." I have. They're
recommended. I like them.
So guys, as a reminder, please, please remember, if you see "Do you have?" or "Did you have?"
don't think, "Have, have, have." "Oh, yes, I have." "No, I haven't." Use the auxiliary
verb, the first verb. Okay?
So guys, if you want to test your understanding on this material, and make sure that you never
confuse "Yes, I do" or "Yes, I have" again, check out the quiz on www.engvid.com. Good
luck and take care.
