Sure! Here’s how the paragraph would look with appropriate pronouns inserted:
"I'm going to tell you something about life in England in 1665. Life was hard then. Some people in some places were rich, but there were lots of very poor people everywhere. The worst thing was the dirt - you couldn't get away from it anywhere, and there was fear of getting ill. There wasn't anything you could do to get better if you got ill, and because there weren't enough doctors to help you. Many people died, but in 1666 something happened to change the situation - there was an enormous fire in London and lots of the rats, which carry illness, were killed. After that, fewer people died. There were rats everywhere."
Feel free to ask if you have more sentences or need further assistance!
