In the past two weeks, we learned how to change regular and irregular verbs into the simple past tense. In today’s English Learning Tips for Newcomers, we take a look at the differences between the simple past tense and the present perfect tense. Many English learners confuse these two tenses.
We summarize the differences between the two in this table below:
|The Simple Past||The Present Perfect|
|verb in simple past||has/have + verb in past participle|
|Referring to an action or event that took place at a specific time||Referring to an action or event that took place at an unknown time in the past|
|A point of time in the past||A period or duration of time up to now|
|with no result or effect in the present||emphasizes the present effect of a past event|
|Used with “finished” time words & phrases such as: yesterday, last week, two months ago, last year, in 1995, etc.||Used with “unfinished” time words & phrases such as: today, this week, this year, in the last six months, etc.|
Pay special attention that the present perfect is often used with these words:
1. “for” and “since” indicate the duration of an action or event. When you see phrases lead by “for” and “since”, use present perfect.
She’s been in Calgary for fifteen years.
She’s been in Calgary since 2005
2. “Never” and “ever” require the present perfect.
I have never eaten durian.
Have you ever been married?
The present perfect can be challenging! It may be helpful to ask yourself:
- Did the action happen in a clearly completed timeframe in the past? (simple past)
- Is the timeframe unclear, or started in the past and continues to the present? (present perfect).
