Past tense forms in English require understanding of both regular and irregular verb patterns, particularly focusing on the estructura del pasado continuo en inglés.

Definition: Past Simple describes completed actions in the past, typically formed by adding '-ed' to regular verbs.

Highlight: Irregular verbs have special past forms that must be memorized, such as 'go → went'.

Example: "I went to bed really late last night" demonstrates irregular verb usage.

Definition: Past Continuous describes ongoing actions in the past, formed with 'was/were' + verb + -ing.

Example: "Were you doing your homework when I called?" shows typical past continuous usage in questions.

Vocabulary: The auxiliaries 'was' and 'were' are essential for forming past continuous tense, with 'was' used for I/he/she/it and 'were' for you/we/they.

The present tenses in English follow distinct patterns and rules for expressing different types of actions. The present continuous and present simple serve different purposes in communication.

Example: "She plays basket very well" shows regular action in present simple.

Vocabulary: The auxiliary verb "do/does" is used to form questions and negatives in Present Simple.
