Past Simple vs Present Perfect - Exercises

These exercises focus on Past Simple vs Present Perfect

What Are the Past Simple and Present Perfect Tenses?

⭐ Past Simple is used for actions completed in the past with no connection to the present.

Structure: Subject + past form of the verb

⭐ Present Perfect is used for actions that happened in the past but are still relevant or connected to the present.

Structure: Subject + have/has + past participle

Example: "I have watched that movie."

Key Differences Between Past Simple and Present Perfect

When to Use Past Simple

⭐ For Actions Completed in the Past with a Specific Time
Use Past Simple when an action is finished and there is a clear time reference.

Examples:

"I visited my grandparents last weekend."

"She graduated in 2020."

"They moved to Canada two years ago."

⭐ For a Sequence of Past Events
Past Simple is used to list a series of events in the past.

Example: "I woke up, took a shower, and had breakfast."

⭐ With Time Expressions Specific to the Past
Words like "yesterday," "last week," "in 2005," or "two days ago" are often used with Past Simple.

Example: "I called him yesterday."

When to Use Present Perfect

⭐ To Describe Experiences (Without a Specific Time)
Use Present Perfect to describe actions that happened at some point in the past, but the exact time isn’t important.

Examples:

"I have traveled to Japan." (At some point in my life, I went to Japan.)

"Have you ever eaten sushi?"

⭐ For Recent Actions with a Connection to Now
When an action just happened and it’s relevant to the present, we use Present Perfect.

Examples:

"She has just finished her homework."

"I have already seen that movie."

⭐ For Actions That Started in the Past and Continue to Now
Use Present Perfect when an action began in the past and still affects the present.

Examples:

"They have lived in this house for 10 years."

"I have known him since high school."

Common Mistakes

1. Using Present Perfect with a Specific Time
   Many learners mistakenly use Present Perfect with specific times in the past. Remember, if you mention an exact time, use Past Simple.

• Incorrect: "I have met him last month."

• Correct: "I met him last month."

2. Using Past Simple for Unfinished Actions
   If an action began in the past and is still happening, use Present Perfect.

• Incorrect: "I lived here for three years." (This implies you no longer live there.)

• Correct: "I have lived here for three years." (You still live there.)

3. Forgetting the Past Participle Form in Present Perfect
   The Present Perfect needs the past participle, not the base form.

• Incorrect: "I have see this movie."

• Correct: "I have seen this movie."

Examples in Everyday Conversations

• Talking about Life Experiences

Present Perfect: "Have you ever been to Italy?" (Life experience with no specific time)

Past Simple: "Yes, I went there last summer." (Specific past time)

• Discussing Recent Actions

Present Perfect: "She has just arrived." (The effect of arrival is relevant now)

Past Simple: "She arrived an hour ago." (Exact time given)

• Describing Changes Over Time

Present Perfect: "The company has grown a lot since 2015." (Started in the past, continues to affect the present)

Past Simple: "The company grew in 2015." (Action completed in the past)

FAQ

When should I use Past Simple vs. Present Perfect?

Use Past Simple for completed actions with a specific past time (e.g., "I visited last year"). Use Present Perfect when the time is not important, or when the action connects to the present (e.g., "I have visited").

Can I use Present Perfect with "yesterday"?

No, Present Perfect is not used with specific past times. Use Past Simple for "yesterday": "I saw him yesterday."

3. How do I form questions in Present Perfect?

Use Have/Has + subject + past participle. Example: "Have you ever visited Paris?"

What’s the difference between “for” and “since” in Present Perfect?

For shows the duration of time (e.g., "for two years"), and since shows the starting point (e.g., "since 2021").

What’s a common mistake with these tenses?

A common mistake is using Present Perfect with a specific past time (like "last week") when it should be Past Simple.
