Okay so gerunds are a form that is derived from a verb but that functions as a noun, in English ending in -ing, example would be like asking in 'do you mind my asking you?'
So the first one would be 'giggling', then the second one would be 'fixing.'
the next two would be a bit harder because there are no words that have a prefix of -ing, but im not to sure about them because i dont think they have a gerund in them...
but the next ones are, 'laughing' and 'squinting'
sorry i couldnt help with all of them.
