							| when / while 
 |  
							| As your advice is always really helpful, I �m bothering you again. I �m a bit confused as I have seen in a book that the structure to combine past simple and past continuous in a sentence using when or while was a t follows:
 
 when  + past simple
 while + past continuous
 
 "When I saw the accident, I was going home. "
 "I saw the accident while I was going home. "
 
 
 But then in another book there was an example saying :
 
 "When Sara was watching TV, the telphone rang."
 
 Is it also correct???? So what is the rule to teach?? What �s the difference between them???
 
 Thanks in advance!!!!

							| I believe that you can use "when" with both Past Simple and Continuous but you use "while" only with  Past Continuous. regards :)

							| i support anielka view that is to say "when" is used with simple and continous past  for both  short and long actions ."while" is just for long actions . |  13 Nov 2009

							| I probably would say When I saw the accident, I was on my way home.
 
 Or I saw the accident while on my way home.

							| After "when", you can have either simple past or past continuous as the examples you gave clearly show. 
 When she was watching TV...  or
 When I saw the accident...
 
 But after "while" you can only have past continuous:
 
 I saw the accident while I was going home.  (OK)
 
 While I saw the accident (WRONG)
 
 I hope this helps.

							| I saw Peter when I was shopping with Mel. I saw Peter while I was shopping with Mel.
 
 So both sentences are correct. Right?
 
 Thanks a lot!!!!  You are always helpful!!!

							| When and while are often synonymous. 
 Here �s an example from the book "Otherwise Engaged": They chatted for a minute while they helped themselves to salad fixings.
 
 I wouldn �t use continuous after while here.
 
 This is just one of many examples that I could give you.
 
 Cheers!

							| I usually tell my students to observe which action is longer. In your example you say: "When I was watching TV the phone rang". Certainly the action of watching TV is much longer as a phone ringing. Probably that�ll help to come to a conclusion of using continous or simple past. |  13 Nov 2009
