Hi, everyone. I’m Alex.
Thanks for clicking, and welcome to this lesson on “Do
and Did in Affirmative Sentences”. So, by this point, you’re probably
familiar with using “do” and “did” in three
different contexts. And specifically, I’m talking about
“do” and “did” as auxiliary verbs. So you can use “do” and “did” most commonly
in questions. So: “Where do you live?”, “Do you like cheese?”
for example. You can also use “do” and
“did” in negatives, so: “I don’t want to do that.”, “He didn’t start
the test on time.” And you can also use it
in short answers, like: “Yes I do.”, “No I don’t.”, “Yes
he did.”, “No she didn’t.” Okay? However, the focus of this lesson is on using
“do” and “did” in affirmative sentences. And it is possible in two different contexts.
So, like the board says, they can also be used in the affirmative to
show, number one, contrast. So if you really want to emphasize a
contrast between two different things, you can use “do” or “did”
in the following way. Check out this example. “He didn’t like the movie,
but he did like the music.” Okay? So if you go to a theatre and
you watch a film, you can say: “Hmm, I didn’t like this,
but I did like this.” So you’re emphasizing a contrast.
You can do this in many contexts. Many things where you have differing opinions
or different feelings about something. If you go to a restaurant,
you can say: “Mm, I didn’t like the food,
but I did like the service.” So, the service was really good,
but the food wasn’t good. So: “I didn’t like this,
but I did like this.”, “I don’t like this,
but I do like this.” or: “I do want this
or need this.” etc. All right, secondly, you can use “do” and “did”
to show emphasize or to give clarification to something. So what I mean by this is if you
are walking through, you know, a department store and, hmm, you’re looking at a refrigerator with
your girlfriend, your boyfriend, your husband, or wife and they’re trying to convince you to
buy this fridge, this new refrigerator. And then you think: “Hmm, we do need a new
fridge.” So, we need a fridge, a new fridge. You can also say: “You know what?
We do need a new fridge.” So you are emphasizing your
need for that refrigerator. You can also clarify: “Hey, why isn’t…?” For
example: -“Why isn’t Mark here?” -“Well, he did say…”
Not just: “He said”, “He did say he was
going to be late.” So, if you’re waiting for Mark, and you know what?
Yeah, he did say that he was going to be late. So you’re clarifying and you’re
emphasizing what he said. Okay? So, just as a reminder, “do” and “did” are not
only for questions, not only for negatives, not only for short answers, but they can also
be used to show contrast and to show emphasis. All right? So, now, you do need to do the quiz to make
