Debating has strict rules of conduct and quite sophisticated arguing techniques and you will often be in a position where you will have to argue the opposite of what you believe in.
The team that agrees with the topic is called the AFFIRMATIVE (or the `government' in parliamentary debating) and the team that disagrees with the topic is called the NEGATIVE (or the `opposition' in parliamentary debating).
For example in the topic "That the zoos should be closed" an argument may be: "the zoos should be closed because they confine the animals in an unnatural environment".
the most essential part of some idea or experience
Any examples that you use should be relevant to the topic at hand. Examples which have very little or nothing to do with the topic only make a speech look weak and lacking substance .
Watching the news helps (but watch a credible broadcast like the ABC , you are hardly likely to get a topic on some heartwarming story about a lost cat in western Sydney) as does reading a good paper or periodical like the Canberra Times or the Sydney Morning Herald.
marked by an orderly and coherent relation of parts
Each member of the team needs to reinforce the team line and be consistent with what has already been said and what will be said by the other members of their team.
People that do that aren't entering the spirit or developing the skills of debating and end up looking really silly getting stuck on a word they just can't say.
