One possible version：
A photo exhibition showing the great changes of our city will be held this Saturday from 8 am to 4 pm in the Palace of Culture. All the photos taken by some well-known photographers have reflected the changes of our city over the past 40 years.
The students，including exchange students，are welcome to attend this exhibition，which will contribute to your understanding of the development of our city. I hope you can show up at the exhibition.
After appreciating all the photos，you will be amazed at the great changes of our city. That is，our city is becoming more and more prosperous and people’s life is becoming better and better. I believe you must have your own ideas and if so，do you mind if you share your ideas in the form of an article with me?
All the best to you!
