English Verb Tenses Explained

Recognize the core structure of perfect tenses as a form of the auxiliary verb 'to have' + a past participle.

Form the past participle of common IT-related regular and irregular verbs (e.g., deploy/deployed, write/written, build/built).

Construct Present Perfect sentences to describe completed actions with a result in the present (e.g., 'I have fixed the bug').

Construct Present Perfect Continuous sentences for actions that started in the past and are still in progress (e.g., 'I have been monitoring the server').

Construct Present Perfect Passive sentences to emphasize the recipient of an action (e.g., 'The bug has been fixed by the team').

Use the Past Perfect to construct sentences where one past action finished before another past action began (e.g., 'We had finished the migration before the outage occurred').

Use the Past Perfect Continuous to describe an ongoing past action that was interrupted by another past event (e.g., 'The script had been running for hours when the server crashed').

Use the Future Perfect to state that an action will be completed by a specific future deadline (e.g., 'By Friday, we will have deployed the new feature').

Use the Future Perfect Continuous to state the duration of an activity at a certain point in the future (e.g., 'By 6 PM, I will have been coding for ten hours').
