Key Differences

Time Reference:
- Simple Past: Specific past time; not relevant to the present.

- Present Perfect: Action may continue or have effects on the present.

- Present Perfect: "I have seen that movie before."

Common Errors to Avoid

Confusing specific past time with present relevance.
Using present perfect with a specific time expression (e.g., "I have seen it yesterday" is incorrect).

Simple Past

Indicates actions completed at a specific time in the past.
Formed using the subject followed by the past form of the verb; regular verbs typically add -ed while irregular verbs vary.
Used for specific past references, such as "I visited Paris last year."
Demonstrates actions that are fully completed, for instance, "She finished her homework."
Suitable for sequential actions, as in "He woke up, ate breakfast, and left for work."
Common keywords include: yesterday, last week, in 2010, ago, and when.

Present Perfect

Connects past actions to the present and signifies actions that have current relevance or occurred during unspecified times.
