A gap year allows participants to find passion in their life.
It’s best to avoid this phrase altogether. First of all it’s redundant, and secondly it’s easy to introduce error. I know my own students always write ‘their’ (plural) ‘life’ (singular).
The following are possible:
- A gap year allows participants to find passion.
- A gap year allows participants to find passion in their lives.
Once again, the first of these examples is preferable – we know that you’re talking about the participants’ lives and not the lives of cats and dogs!
In conclusion, long working hours are necessary for human beings.
I’m guessing this may be a cultural issue.
Let’s try a quick test. Which of the following sentences is NOT about working hours and humans?
- Long working hours are necessary for human beings.
- Long working hours are necessary.
- Long working hours are necessary for ants.
Hopefully you chose number 3. In any discussion of working hours, and indeed of many other topics, we’re usually talking about human beings, unless otherwise specified.
The only time we really need to mention humans is when we’re contrasting them with non-humans!
