What is the Present Perfect?
We use the Present Perfect to talk about experiences in your life. The exact time is not important, or you don’t know it.
- It connects the past to the present moment.
- We form it with have 或 has + the past participle of the verb.
Common words we use with the Present Perfect are ever (for questions), never (for zero experiences), and before.
What is the Past Simple?
We use the Past Simple to talk about actions that finished at a specific time in the past. The time is clear.
- The action started and finished at a known time.
- We form it with the verb + -ed for regular verbs, or a special form for irregular verbs.
Common words we use with the Past Simple are yesterday, ago （例如，, two weeks ago), last week/month/year, and specific dates or times (e.g., in 2022, at 5 o'clock).
When to Use Which One?
The key difference is about *when* the action happened and if it connects to *now*.
- Use the Present Perfect for general life experiences: I have never eaten sushi. (in my whole life, until now).
- Use the Past Simple for specific past events: I ate pizza yesterday. (a specific time: yesterday).
- If you ask "Have you ever...?", you are asking about a life experience.
- If you ask "When did you...?", you are asking about a specific past time.
Special Word: 'Been'
这个词 been is important for the Present Perfect.
- Been is the past participle of the verbs go 和 be.
- We use it to say you visited a place and came back. For example: I have been to the zoo. (I went there and now I am back).

练习
西班牙语母语者常犯的错误
Many Spanish speakers make two common mistakes:
- Using Past Simple for life experiences: In Spanish, you might say "Fui a Madrid" for "I have been to Madrid." But in English, for a general life experience without a specific time, use the Present Perfect.
Wrong: I went to Madrid. (if you mean 'in my life')
Right: I have been to Madrid. - Using Present Perfect with specific past time expressions: Do not use words like yesterday 或 last week with the Present Perfect. These words need the Past Simple.
Wrong: I have seen that movie last night.
Right: I saw that movie last night.
