Why Korean speakers turn "I've eaten" into "I ate"

Have You Done It, or Did You Do It?

Rule: If there's a specific time word (yesterday, in 2020, last week) → use simple past. If there's no specific time, or you're talking about experience/result → use present perfect (have + past participle).

Fix these sentences

1. I already finish my homework. → ___________________________
2. She live in Korea for five years. → ___________________________
3. Did you ever eat octopus? → ___________________________
4. I lost my phone yesterday, so now I don't have it. (Is this correct? Circle: YES / NO)
5. He work here since March. → ___________________________

Circle the signal word, then choose the correct verb

1. I (see / have seen) that movie three times.
2. She (finished / has finished) the test at 3pm yesterday.
3. We (never try / have never tried) kimchi pizza.
4. They (live / have lived) in Seoul since 2021.

Speaking round

Ask a partner three questions starting with "Have you ever..." Write down their answers using simple past, because once they tell you the specific detail, the time becomes known.

Example: "Have you ever been to Japan?" → "Yes." → "When did you go?" → "I went in 2023."
