Verb Tenses

A verb tense indicates the time of an action or state of being, showing whether it is in the past, present, or future.

The present continuous tense describes actions that are currently happening or ongoing. It is formed using 'am/is/are' + verb-ing (e.g., 'is sleeping').

The simple past tense describes actions that were completed in the past. It often ends in -ed for regular verbs (e.g., 'walked').

The future simple tense describes actions that will happen in the future. It is formed using 'will' + base form of the verb (e.g., 'will eat').

The present simple tense is formed using the base form of the verb for all subjects except third-person singular, which adds -s or -es (e.g., 'he walks').

'Is sleeping' is present continuous, indicating an ongoing action, while 'sleeps' is present simple, indicating a habitual action.

The correct form is 'destroy' because it refers to a general truth.

The past form of 'see' is 'saw'.

A future tense sentence typically follows the structure: subject + will + base form of the verb (e.g., 'He will go').

The negative form of the simple past tense is formed using 'did not' + base form of the verb (e.g., 'did not like').
