I'll be glad to check your sentences.
can you at least start the second one for me please
Katy is thinking she might like to become a marine biologist one day
Katy is thinking she might like to become a marine biologist, but she's also interested in veterinary science.
To form a compound sentence, you can combine these two simple sentences using a coordinating conjunction, such as "and," "but," or "so." Here are a few examples:
1. Dolphins are very intelligent, social creatures, and Katy is thinking she might like to become a marine biologist one day.
2. Dolphins are very intelligent, social creatures, but Katy is thinking she might like to become a marine biologist one day.
3. Dolphins are very intelligent, social creatures, so Katy is thinking she might like to become a marine biologist one day.
These examples demonstrate how the coordinating conjunction joins the two simple sentences to create a compound sentence.
