Sofía: I DO care, Kenji. I just don't panic out loud like you do.
Ben: It was such a stressful week that I actually finished something early, for once.
Abuela Carmen: The pressure DID do something good, then. Write that down before it disappears.
Common mistake: “I really understand why you're upset.” — Correct: “I DO understand why you're upset.”
Adding do/does/did before the base verb, or using so/such before an adjective or noun, adds emphasis — it insists on something that might be doubted.
Two ways to add emphasis
Tool
Structure
Example
do/does/did + base verb
stressed auxiliary + verb
I DO understand you.
so + adjective (+ that)
so + adj + that + result
It was so difficult that everyone struggled.
such (a/an) + adjective + noun (+ that)
such + noun phrase + that + result
It was such a good day that nobody left.
I DO understand why you're upset.
She DOES care about this project, even if it doesn't look like it.
It was such a good day that nobody wanted to leave.
The exam was so difficult that half the class failed.
It wasn't such a bad idea after all.
The traffic wasn't so bad that we missed the flight.
It didn't seem such a big deal at the time.
Do you really understand, or are you just saying that?
Was it such a good day that you didn't want to leave?
Did the exam really matter that much to you?
Do you actually understand? I DO understand, yes.
Was the exam that hard? Yes, it was so hard that half the class failed.
Did you enjoy the day? I DID enjoy it, actually.
Practice
I ___ understand why you're upset. (DO, am, have)
It was ___ good day that nobody wanted to leave. (such a, so, very)
The exam was ___ difficult that half the class failed. (so, such, such a)
'I DO understand' is more emphatic than 'I understand'.
'So' is used directly before a noun (so a good day).
'Such' is used before an adjective + noun combination (such a good day).
She ___ care about this project, even if it doesn't show.
The traffic wasn't ___ bad that we missed the flight.
It wasn't ___ bad idea after all.
Unscramble: I, DO, understand, why, you're, upset
Unscramble: it, was, such, a, good, day, that, nobody, left
Find the mistake: It was so good day that nobody wanted to leave.
I really do understand you. — Rewrite with emphatic stress using DO.
The exam was very difficult; half the class failed. — Combine using 'so...that'.
It was a very good day; nobody wanted to leave. — Combine using 'such a...that'.
It was such a bad idea. — Write a version meaning the opposite (it wasn't bad).
Do you really enjoy studying grammar? (answer with emphasis using DO)
Listening
Kenji: You never seem to care about the results.
Sofía: I DO care, Kenji. I just don't panic out loud like you do.
Ben: It was such a stressful week that I actually finished something early, for once.
Kenji: That IS surprising, coming from you.
Sofía: The pressure did do something good, then.
Ben: Don't get used to it. It was such a rare event.
Reading
Kenji has always assumed Sofía doesn't worry about deadlines — she never raises her voice, never seems rattled. 'I DO worry,' she told him once, 'I just don't show it the way you do.' It was such a strange thing to hear that Kenji actually stopped and reconsidered everything he thought he knew about her. The week that followed was so demanding that even Sofía's calm cracked a little — she DID admit, finally, that it had been hard. Ben, of all people, finished his part early that week, which was such a rare event that Abuela Carmen wrote the date down, just so nobody would forget it happened.
Sofía told Kenji she doesn't worry about deadlines.
