Question

英语句型
What began twenty-one months ago in the depths of winter must not end on this autumn night.This victory alone is not the change we seek – it is only the chance for us to make that change.And that cannot happen if we go back to the way things were.It cannot happen without you.
So let us summon a new spirit of patriotism; of service and responsibility where each of us resolves to pitch in and work harder and look after not only ourselves,but each other.
