Fill in the gaps. Don't use any punctuation marks: 1. I wonder how many accidents I've
in my life.
2. I've
lost count of the number
of times I've hit my thumb with a hammer.
3. He's a real accident looking for somewhere

1. I wonder how many accidents I've had in my life.
Explanation: The correct word to fill in the gap is "had" because it indicates the action of experiencing accidents in the past.

2. I've lost count of the number of times I've hit my thumb with a hammer.
Explanation: The correct word to fill in the first gap is "lost" because it shows the action of not being able to keep track or remember the specific number. The second gap should be filled with "of" as it indicates the connection between the phrase "number of times" and "I've hit my thumb with a hammer."

3. He's a real accident looking for somewhere.
Explanation: The correct phrase to fill in the gap is "to happen." The sentence would then be "He's a real accident looking for somewhere to happen." This phrase is a commonly used idiom meaning that someone is very likely to cause or be involved in an accident. In this context, it implies that the person is accident-prone or clumsy.
