This slides are a brief explanation of the topic past tense, which will be shown in my blog to help students improve their linguistic abilities.

1. Past tense
By Santiago Tamayo Ramirez

2. Regular & Irregular verbs
• The regular verbs do not change the form when they are applied whether in
simple past, present perfect and past perfect.
Some examples of regular verbs are: I played yesteday with my sister, I
have watched since I was 8 years old. I had watched something strange.
• The irregular verbs change in their past form as their participle one.
Some examples of irregular verbs are: I went to bed early, I have slept all
night, I had known that you were sick.
