The simple past tense is formed by adding "-ed" to the base form of regular verbs or using irregular verb forms. For example:- I walked to the park yesterday.- They studied for the exam last night.- She ate lunch an hour ago.These sentences show actions or events that occurred at a specific time in the past.Present Continuous Tense:The present continuous tense is used to express actions or events that are happening at the moment of speaking or during a specific time frame.

The future tenses are used to describe actions or events that will happen in the future.Simple Future Tense:The simple future tense is formed using the auxiliary verb "will" or "shall" with the base form of the main verb. For example:- I will go to the party tomorrow.- They will finish the project by next week.- She shall take the bus to work.These sentences express actions or events that will occur at some point in the future.Future Continuous Tense:The future continuous tense is used to describe actions or eventsthat will be in progress at a specific time in the future.
