Dear sirs,

I made a distinction between Am & Br. English(spelling , pronunciation, or different word or phrases)
but no body cares here because i live in Iraq and i would like to discuss that with university professors so, what is your advise to do?

Hi, Alan

I have a question too. Does "stir" have to be in the Present form? Shouldn't it be "stirred"?
I mean, the question was "how did you make it", and not "how do you make it"

Thanks !

Hello Torsten,
One day ago I did the 5 simple present tests. I don't control but today I saw again these tests.To my great surprise I saw my pictures disappeared in the 2 and 3 tests. I did them again. This isn't the first occasion - so that's why I never control whether my picture stays there or not. I learned that I can't be right. My pictures dissapeared again.But to-day accidentally I noticed that this game isn't over.My pictures disappear as if I never did these tests.

Correction:
They dissappear as if I have never done them. The most interesting thing that they disappear from my progrest report also.
When I finish a test it is written how many mistakes there are in it,after I always see my progress report . After I control whether the picture went to its place.The pictures were there.
My question: I don't want to put my picture there. I don't need fuming!
