2. Are there any syntactic structures that create equivalence and contrast? B.Obama’s Inaugural Address (January 20th, 2009)
‘My fellow citizens:

---

Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America - they will be met.

On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord.

On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics.

We remain a young nation, but in the words of Scripture, the time has come to set aside childish things. The time has come to reaffirm our enduring spirit; to choose our better history; to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free, and all deserve a chance to pursue their full measure of happiness.’

Like all the best beginnings, this one starts with Pooh, who has woken up with a start in the middle of the night. He has been woken up by a noise, so he gets up just to check on his honey, and all is fine, so he goes back to bed again. But there's the noise again, so Pooh asks the noise if it is Piglet or Christopher Robin or Eeyore, but there is no answer, so Pooh tries to get back to sleep.But there it is again! It's a kind  noise, which doesn't sound like something Piglet or Christopher Robin or Eeyore would say, but Pooh is sleepy so that probably explains his confusion. And now he has heard the noise again he realises that it is not a usual noise, and in fact it is something he has never heard in the forest before, which must mean that there is a Strange Animal outside his house!So Pooh rather bravely gets up and opens his front door so that he can tell the Strange Animal to pipe down please. And the Strange Animal is sitting right there, so Pooh says "Hallo!", and the animal says "Hallo!" back. Pooh is so startled that all he can think of to say is "Hallo!" again, and then the animal says "Hallo!" again too, and then Pooh is still rather stunned, so he says "Hallo!" for a third time, and the animal says "Hallo!" back for a third time, while wondering how long they are going to "Hallo!" for.
