- The American government should give a big fine to ships' owners who lets oil overflow in the ocean. They have to perform this firmly and show no mercy.
- Do these make any sense and natural?
Thanks so much in advance
- The American government should give (maybe "impose" sounds better) a big fine to ships' owners who let (more than one owner = no -s) oil overflow in the ocean. They have to perform this firmly and show no mercy.
I agree with Charliedeut that 'impose' sound better, but I would use 'on' rather than 'to'.
I don't like 'perform firmly'; I think 'do' is sufficient.
- I'd use 'large' rather than 'big'. Or perhaps 'significant', 'punitive'.
- You also should write "into the ocean". There are some of us who would assume that oil overflowing in the ocean is already in ocean. (similarly to all the other examples of 'in' v. 'into' and 'on' v. 'onto'.
- 'Overflow' is also questionable. Something 'overflows' when you are filling a up a vessel and the material keeps pouring after the vessel is full. I think most oil spills occur through accidents or faulty equipment rather than simply letting it overflow. (Maybe I'm wrong.)
