Is it correct to say that she was being taken to hospital by ambulance but she died on her way?

I just want to use it for my translating job, so it didn't happen.

A: Yes, it is correct, except you need an article or a quantifier before "hospital" and "ambulance." Quantifiers like "some" or "any" must be used in specific circumstances though, so you should be aware of what those are before you choose which one to use. Often, native English speakers can pick which one to use based on what "sounds right," but there are actually rules. You should also make sure you use proper punctuation when you write it out. In this case, you should place a comma before "but" because it is a coordinating conjunction.
