1. I’ve had serious ones where I’ve ended up in the hospital.
Explanation: In this sentence, the word "serious" should be followed by the word "ones" to make it clear that the speaker is referring to serious accidents. Additionally, "hospital" should be written as a separate word, not combined with "the."

2. I suppose that’s because I work and that’s not so dangerous.
Explanation: In this sentence, the word "Iwork" should be written as two separate words, "I work." This makes it clear that the speaker is talking about their job. Additionally, there should be a space between "so" and "dangerous."

3. He’s a real accident looking for somewhere to happen.
Explanation: In this sentence, the word "somewhere" should be added at the end to complete the phrase "somewhere to happen." This expression means that the person being described is constantly getting into accidents or causing accidents. Also, there should be a space between "real" and "accident" to distinguish them as two separate words.
