Answer 1

★ Answers :-

1. The young child hasn't gone home till 4 pm.

2. Haven't the team played well ?

3. Haven't students do well in the class test ?

★ Explanation :-

• Formula of present perfect tense : Sub + has/have + 3rd form of main verb + object + remaining.
• As the 1st sentence is in negative form it will take 'not' after the has/have verb.
• The 2nd and 3rd sentences are in interrogative form. The has/have verb will take place before the subject.
• We have to notice the subject if it is singular or plural. Singular subject would take has verb and plural will take have verb.

• Present Perfect: The present perfect is used to indicate a link between the present and the past. The time of the action is before now but not specified, and we are often more interested in the result than in the action itself.

Forming Present Perfect

The present perfect of any verb is composed of two elements:

• the appropriate form of the auxiliary verb to have (present tense), plus the past participle of the main verb.
• The past participle of a regular verb is base+ed, e.g. played, arrived, looked.
