Grammar check for an 8-year-old: Fixing 'Sprinkler trucks water trees and wet roads to keep dust down'

Corrected sentence: Sprinkler trucks spray water on trees and roads to keep down the dust.

Why this is better (step by step):

1. Capital letter and period: The original sentence already had a capital S and a period, so that is good.
2. Subject and verb: "Sprinkler trucks" is the subject (who does something). The verb should show the action. "Spray water on" is a clear action phrase. "Water trees" is okay, but "wet roads" sounds like a description, not the action. So we use "spray water on trees and roads."
3. Word order and meaning: "Wet roads" describes roads that are already wet. We want to say what the trucks do, so we say they "spray water on roads." That makes the action clear.
4. Dust phrase: "Keep down the dust" or "keep dust down" both work. I used "keep down the dust" to sound natural, but "keep dust down" is also fine.

Other simple options you could use:

• Sprinkler trucks water trees and roads to keep dust down.
• Sprinkler trucks spray water on trees and on roads to keep the dust down.

All of these are correct. The main change is to make the action clear by using "spray water on" or just "water" and avoid saying "wet roads" as if it were a thing the trucks do by itself.
