Rainy season

Sai Gon has two different seasons: rainy and dry seasons. The rainy season lasts from June to November. The rainy season in Sai Gon starts with the short rains. These rains come suddenly in the morning or afternoon while it is sunny and very hot. They just occur so in a few minutes the road turns dry immediately after they've gone away. They are like the people who live here, always in a hurry.
After about three weeks with sudden short rains, Sai Gon enters the major rainy season. That time is for the rains which last many hours. Sometimes, it rains heavily, sometimes lightly. Rain helps clean the dust and refresh the air and lower the summer temperature. The rainy season would be beautiful if there were no accompanying problems: traffic jams and flooded streets.

Hello Pham Cong Duc,

There are just a few minor mistakes in this text but it is fuly understandable. In the last sentence you use a 2nd conditional for a hypothetical situation the structure is if + past simple, would + infinitive.

Hope this helps
