⏰ Lesson 6: Present Perfect vs Past Simple

Life Experiences vs. Specific Moments - Understanding the Difference!

Welcome! Life Stories - Two Ways to Tell Them

Warm-Up: Talk with Your Teacher (3 minutes)

Answer these questions together:

  • Have you ever been to another country? (Which one? When did you go?)
  • Have you ever tried a really unusual food? (What was it? When did you try it?)
  • Have you ever met someone famous? (Who? When did you meet them?)

🤔 Did you notice? When your teacher asked "Have you ever...?" that's Present Perfect. When they asked "When did you...?" that's Past Simple!

Today's Big Question

When do we use Present Perfect and when do we use Past Simple?

Present Perfect

"I have visited Paris."

(Life experience - time not important)

Past Simple

"I visited Paris in 2019."

(Specific moment - time is important)

What We'll Learn Today

  • ✅ The difference between "unfinished time" and "finished time"
  • ✅ When to use each tense
  • ✅ How to tell your life story correctly
  • ✅ Time markers that signal which tense to use
  • ✅ How to interview someone about their experiences

💡 Pro Tip: Think of Present Perfect as the "biography" tense (life so far) and Past Simple as the "history book" tense (finished events with dates)!

🔍 Discover the Rules

The Key Concept: Finished vs. Unfinished Time

⏳ Present Perfect = UNFINISHED TIME

Time periods that include NOW:

  • in my life (life continues!)
  • this week/month/year
  • today
  • ever / never (in all your life so far)
Example:
"I have read three books this month."
(This month isn't finished yet!)

✅ Past Simple = FINISHED TIME

Time periods that are complete:

  • yesterday
  • last week/month/year
  • in 2019, in June
  • when I was a child
  • ago (two days ago)
Example:
"I read three books last month."
(Last month is finished!)

Pattern Discovery Activity

Discuss with your teacher: Why is each sentence correct?

1a. "I have been to Japan."

Why Present Perfect?

1b. "I went to Japan in 2018."

Why Past Simple?

2a. "Have you ever eaten snails?"

Why Present Perfect?

2b. "When did you eat them?"

Why Past Simple?

3a. "She has lived here for 5 years."

Why Present Perfect?

3b. "She lived in London from 2010 to 2015."

Why Past Simple?

Quick Check: Which Tense?

Discuss with your teacher - which tense would you use and why?

1. "I (see) that movie last weekend."

2. "Have you (see) the new Marvel movie?"

3. "When (you/visit) Paris?"

4. "I (never/try) sushi."

5. "She (study) English when she was at school."

1. saw (Past Simple - "last weekend" = finished time)

2. seen (Present Perfect - "Have you ever...?" = life experience)

3. did you visit (Past Simple - "When" asks for specific time)

4. have never tried (Present Perfect - "never" = in all my life so far)

5. studied (Past Simple - "when she was at school" = finished period)

⚖️ Side-by-Side Comparison

The Question Flow

Natural conversation usually goes like this:

Step 1: Present Perfect (general experience)

"Have you ever been to Italy?"

Step 2: Past Simple (specific details)

"Yes!" → "When did you go?" → "I went in 2019."

"Which cities did you visit?" → "I visited Rome and Venice."

"How long did you stay?" → "I stayed for two weeks."

Common Situations Compared

Situation 1: Travel

Present Perfect:

"I've been to 15 countries."

(Life experience count)

Past Simple:

"I went to Thailand last summer."

(Specific trip)

Situation 2: Work/Study

Present Perfect:

"I've worked in three companies."

(Career history)

Past Simple:

"I worked at Google from 2018 to 2020."

(Specific period)

Situation 3: Achievements

Present Perfect:

"I've won two awards."

(Total achievements)

Past Simple:

"I won the first award in 2020."

(Specific achievement)

Practice Together: Choose the Right Tense

Discuss each sentence with your teacher and decide which tense fits:

1. "I (lose) my keys yesterday. Have you seen them?"

2. " (you/ever/eat) Mexican food?" "Yes!" "When (you/try) it?"

3. "She (live) in Paris for three years. She still lives there now."

4. "We (meet) in 2015 and we (be) friends ever since."

5. "I (just/finish) my homework!" "When (you/start) it?"

1. lost (Past Simple - "yesterday" = finished time)

2. Have you ever eaten / did you try (Perfect for experience, then Past for specific time)

3. has lived (Present Perfect - still continues now!)

4. met / have been (Past for specific meeting, Perfect for ongoing friendship)

5. have just finished / did you start (Perfect for recent action, Past for specific start time)

The Tricky One: "How long...?"

🤔 Rule: "How long" + Present Perfect = STILL TRUE NOW

✅ "How long have you lived here?" → You still live here

✅ "How long did you live in Tokyo?" → You don't live there anymore
