Autumn is here, the brightest time of the year. She painted everything around in her favorite colors. Now on the streets of the city there are yellow, red and orange trees. Beauty-autumn endows everyone with coolness. It's not as hot outside as it is in summer. The days are getting shorter and colder.

Autumn is the best time for walks in the park or forest. Everything around is full of colors! Leaves rustle merrily underfoot. Autumn gives us its fruits and pleases us with the last warm rays. The rainy season is about to begin. The colors will leave the streets. Gray weekdays will begin with slush and mud. But it also has its own romance. That's what a different sorceress autumn.

Present Perfect употребляется, когда мы говорим о действиях в без указания времени совершения действия. Past Simple употребляется, когда мы называем точное время совершения действия.
Present Perfect употребляется, когда действие еще продолжается в настоящем или произошло в еще не законченный период времени (в предложении есть today, this week и т. п.). Past Simple употребляется, когда действие уже закончилось и не имеет связи с настоящим (в предложении есть слова yesterday, last week, выражения со словом ago и т. д.)
