Original: At night, when everyone is asleep, the city helpers clean the streets. They fix the roads and pick up trash, so the city looks nice in the morning.
Corrected: At night, when everyone is asleep, city workers clean the streets. They fix the roads and pick up the trash so the city looks nice in the morning.
Why this change?
- “At night, when everyone is asleep,” is an introductory phrase. The comma after it is correct.
- “City helpers” is understandable, but “city workers” sounds more natural in English.
- “Pick up trash” is okay, but “pick up the trash” is a bit clearer in this sentence.
- The comma before “so” is optional. Leaving it out makes the sentence flow smoothly: “pick up the trash so the city looks nice.”
One shorter version: At night, city workers clean the streets, fixing roads and picking up the trash so the city looks nice in the morning.
