Corrected sentence: The pigeon softly coos, and all the animal friends are glad to join the chorus.
What to fix:
- Capitalization: Don't write COOS in all capitals. Use coos (small letters) unless you are shouting or showing special emphasis.
- Punctuation: The comma before and is okay but not necessary here. You can also write: The pigeon softly coos and all the animal friends are glad to join the chorus.
- Words: Everything else is good. The sentence is clear and nice.
Parts of the sentence (easy):
- The pigeon = who the sentence is about (the subject).
- softly = tells how the pigeon coos (an adverb).
- coos = the action the pigeon does (the verb).
- all the animal friends are glad to join the chorus = the second part that tells what the other animals do.
Other simple ways to say this:
- The pigeon coos softly, and the other animals join in.
- The pigeon softly coos. All the animal friends are happy to sing along.
Nice sentence — just change the all-caps word and you are done. Great work!
