Original sentence: On a summer day, if rains while the sun is out, a pretty rainbow shows up.
Correct sentence: On a summer day, if it rains while the sun is out, a pretty rainbow appears.
Why this is better:
- Add "it" — For weather we say "it rains." The original missed the word "it."
- Use a comma — Put a comma after the beginning phrase On a summer day, because it starts the sentence.
- Choose a gentle word — "Appears" sounds a little nicer than "shows up," but both are okay.
Other simple ways to say it:
- When it rains and the sun is out, you can see a pretty rainbow.
- Sometimes, on a sunny rainy day, a colorful rainbow appears.
Try saying the corrected sentence out loud. Nice job noticing the rainbow!
