Let's try to know about tense before knowing your question's answer. Examine these sentences.

• I wrote a letter last week.
• I write this letter now.
• I shall write to my friend next week.

In the first sentence, the verb wrote tells what I did in the past time. In the second sentence, the verb write tells that I do now __that is, at the present time. In the third sentence, the verb shall write tells what I shall do hereafter __that is, in the future.

• Actually when the action denoted by a verb refers to the past time, as in the first sentence, the verb is said to be in the Past Tense.

• When the action denoted by a verb refers to the present time, as in the second sentence, the verb is said to be in the Present Tense.

• When the action denoted by a verb refers to the future time, as in the second sentence, the verb is said to be in the Future Tense.

$\sf \underline {\green {{ Structure \: of \: Past \: Tense :-}}}$

2. When subject is plural -

4. In the case of interrogative sentence -
