							| Verbs of perception 
 |  
							| Hello everyone , 
 I would be grateful if you shared me your experience . 
 Some verbs of perception are followed by  ing- form (GERUND) or base form. 
 Example : I saw the boy running quickly  .                  I saw the boy run quickly  . 
 Is there  a clear difference in meaning or structure . Or it doesnt matter . 
 Please reply. 
 Thank you . |  18 Jul 2013

							| Hi, If we want to say that we heard or saw the whole action from beginning to end, we usually use bare infinitive. Otherwise, we �ll use -ing form . |  18 Jul 2013

							| The -ing form is usually used when you want to emphasize the process over time. If you are considering an event (as if it were just a point in time), you would use the simple present/bare infinitive. We use "watch" more often than "see" for processes over time, except as in your example when the running was over a period of time, but the seeing was at a point.   I saw you hit your sister - a single event.   I saw you hitting your sister - I observed what seemed to be an ongoing action.   Flori �s answer covers it pretty well.   Bruce |  18 Jul 2013
