How do you differentiate between the past tenses?

Answer 1

Simple Past TenseThe past tense is used to express an action that happened in the past. It follows this structure:

• Subject + Past Tense of verb.

Past Perfect TenseThis is used to express an action in the past before another action in the past. It follows this structure:

• Subject + Had + Past Participle.

Past Continuous TenseThis is used to express an action at a specific time in the past. The action started before this time and hasn't finished yet. It follows this structure:

• Subject + Was/Were + Present Participle

Past Perfect Continuous TenseThis is used to express longer actions in the past (i.e. longer than past continuous actions) before another action in the past begins. It follows this structure:

• Subject + Had + Been + Present Participle

Answer 2

The past tense is a grammatical form used to express an action or event that occurred in the past. There are several ways to differentiate between past tenses. One way is by looking at the verb endings. For example, the simple past tense in English often includes the suffix "-ed" for regular verbs (e.g., walked, talked). Another way is by looking at specific verb forms or auxiliary verbs used to indicate past actions, such as "was" or "were" for past continuous or "had" for past perfect.
