							| Hi dears, 
seeking your help , please. I have 2 sentences and Iam confused.How can I illustrate them to my students. The first is  I was cleaning the roof when Helen arrived. the second is  Helen arrived after I had cleaned the roof. as you see the 2 are talking about 2 actions that happened in the past one before the other or one is longer than the other But, how can we differenciate between them  and to make students understand them   |  13 Dec 2011

							| To add to Mouna �s excellent answer, we often use the past continuous (was cleaning) to indicate an activity that was interrupted by an event (Helen arrived), which is what the first sentence does.   The first sentence could also be written, "Helen arrived while I was cleaning the roof." This way the two sentences have similar structures, so it �s even easier to see their differences.   Bruce |  13 Dec 2011

							| Why don �t you ask them to draw two pictures? Or draw them yourself? Ask them to draw you cleaning the roof and someone knocking on the door for the first case and a perfectly clean roof when your friend Helen knocks on the door (you could be sitting in the living room watching TV). Then eliminate the rules by sking them questions, such as "Had I finished cleaning the roof when my friend arrived in both cases?" Make them write the correct sentence next to the corresponding picture! 
 Good luck! |  13 Dec 2011
