Corrected sentence: So many people live in the city. Houses line each street, and cars zip up and down!
Why this is better (easy steps):strong>
- Start sentences with a big letter: 'So' and 'Houses' both start with a capital letter.
- Use a period to finish a sentence: We made the first idea end with a period so it is clear: 'So many people live in the city.'
- Put a comma before 'and' when joining two full ideas: The second part has two full ideas: 'Houses line each street' and 'cars zip up and down.' We put a comma before 'and' to join them smoothly.
Other simple ways to write it:
- So many people live in the city—houses line each street, and cars zip up and down!
- So many people live in the city; houses line each street and cars zip up and down.
Nice work! The sentence already sounded good; these small changes make it easier to read.
