Помогите мне разобраться с временем презент симпл и презент перфект.

Hi, these both tenses are very simple.

Present simple shows when a situation happens everyday

For example I go to school, I drink coffee, She liks ice cream

Present perfect shows the result of the situation

For example I have done this job, I have met him, She has phoned to him.

This tense shows the result 100 %
