Prepositions Followed by Gerunds Clauses: referring to time-related activities
He looked scared before jumping in the pool.
He held his breath before jumping in the pool.
(Before relates two activities. The main clause cannot be a static verb.)
I couldn't understand this situation. If it is true, can you please give me some more information or examples? Why is 'he looked scared before jumping in the pool' wrong?
I don't understand that at all. "He looked scared before jumping in the pool" is absolutely fine. I can't imagine how the writer of that website thinks that the sentence can be "corrected" by changing it to "He held his breath before jumping in the pool". It needs no correction. The statement "Before relates two activities" is incorrect English too.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
