In your correction, you said that "nous avons aussi appris a changer une roue" rather than un pneu.  Une roue translates, as per my dictionary, to be "a wheel," while  "un pneu" is a tire.  I'm probably splitting hairs, but it is different to change a wheel than a tire; the wheel is the base on which the tire sits and would therefore be a much bigger job than changing the tire alone.  As I said, I'm splitting hairs, but want to know if in common parlance, the roue is changed when the pneu is flat.  Also, others have asked the other questions I had - about the use of plus-que-parfait (suggested but not actually used in the "correct" translation) and about the use of encore rather than toujours.  Thanks for your help.  It is greatly appreciated!
