Final answer:
A compound sentence can be formed by combining two main clauses with a coordinating conjunction. One example is 'Mrs. Bowen lost an earring last week, but we found it today.' Consistent tense and proper comma use are crucial for clarity and correctness in compound sentences.
Step-by-step explanation:
To form a compound sentence, you can join two main clauses using a coordinating conjunction such as 'for', 'and', 'nor', 'but', 'or', 'yet', or 'so'. Here's a corrected version of the sentence provided: Mrs. Bowen lost an earring last week, but we found it today.
Now, let's review examples where punctuation should be corrected:
- I finally found my keys, and I got to work just in time.
- Mrs. Contreras threw out her old coffee table and cleaned the carpet.
- Taking the elevator to the roof, we hoped we could see the skyline and the bay.
- Though Susan wasn't feeling well, she went to the store anyway and bought ice cream, pizza, and candy.
- I let my neighbor borrow my phone because she said hers was tapped by the police.
Remember, when forming compound sentences, maintaining consistent tense is important for clarity, as shown in the example: I lost a glove on my walk, but I found it later.
