Hi Jaime,

Thanks for your comment, absolutely it’s worth picking up these queries. Firstly, the words you’re referring to could be a number of things – though often prepostions and adverbs – but we could refer to them in general as superfluous or extraneous words. You’re right that often they can be cut, but they’re also often used for emphasis or to give a little extra push. Often, however, they are simply filler – and as to how they can be overcome, it requires lots of editing to cut all the unnecessary information, we are all guilty of it.

To your specific points from the exercise:
-You could remove “spaced” but that would change the meaning a little; “they are apart” = just their state (and not fully natural, we’d more likely say “they stand apart” for example), but “they are spaced apart” tells us they deliberately positioned this way.
-Absolutely right on this, “between” would be more appropriate, though “through” just about works
-If you mean “in currents waters” this would be incorrect; “current waters” maybe, but more naturally we’d say “in currents” – but in this sentence currents has already been used and “flowing water” provides a broader scope (after all, seawater flows with forces other than just the current).

I’m glad you enjoyed the exercise and that you find it useful!
