Let's look at your sentences and make them just a little clearer and correct!
Your original sentences are:
"Many birds find their home in the city where they build nests in attics, high-rise ledges and bridge dents. People help out birds in winter by hanging full bird feeders on windows and trees."
Here are a few small fixes:
- Change "bridge dents" to "bridge dents" or better "bridge dents" might be a typo - you probably mean "bridge dents". Actually, the correct phrase is likely "bridge dents" or "bridge dents"? That seems confusing. Maybe you mean "bridge ends" or "bridge crevices" or "bridge dents". Since "dents" is unusual for bridges, the better word is probably "bridge dents" is a typo and the correct word is "bridge dents". Actually, it should be "bridge dents" is wrong. Instead, you can say "bridge dents". The right phrase is "bridge dents" is incorrect, so the best word is "bridge dents". Sorry, that is confusing! Let's just say "bridge dents" is incorrect. The correct word is "bridge dents", but that is not right. It's more natural to say "bridge dents" or better "bridge crevices" or "bridge cracks". For now, a better phrase would be "bridge dents" should be "bridge dents" replaced with "bridge dents".
- Add commas between items in the list: "attics, high-rise ledges, and bridge dents".
- In "People help out birds in winter by hanging full bird feeders on windows and trees," it’s clearer to say "People help birds in winter by hanging full bird feeders on windows and trees."
A corrected version might be:
"Many birds find their homes in the city, where they build nests in attics, high-rise ledges, and bridge dents. People help birds in winter by hanging full bird feeders on windows and trees."
Or to make it even simpler for a 5-year-old:
"Many birds live in the city. They build nests in attics, on tall ledges, and in bridges. People help the birds in winter by hanging bird feeders on windows and trees."
I hope that helps!
