Answer 2

Answer:

The train has not left yet.

Present Perfect Tense :

• Present Perfect Tense says that the action is over already but its action is present.

• Leave is base form and its past participle form is left. After 'has' past participle form is used in Present Perfect Tense. 'The train' is a third person singular number, that's why 'has' is auxiliary verb here.

• The above rewrite sentence means that the train didn't leave but it will leave. The rewrite above sentence is an example of Negative Sentence, 'not' after auxiliary verb, 'has' suggests it. We can also say it a simple sentence because it has a finite verb and it is (has) 'left '.

• Example : I have taken my lunch. In this sentence 'lunch' has been taken by me already but its action is Present.
