Some of us feel puzzled about the      (participate) of a debate. Here is some information which will help you get a general idea of it.
Participating in a debate is a useful practice of those who aim to become public speakers. In a formal debate a statement called a “motion” is      (propose). It is defended by the proposers and challenged by their opponents. To become a       (lead) debater it is necessary to acquire several techniques and skills.       experienced debater seeks to persuade others by presenting relevant arguments      (intention), not by the violence of his language. He shows respect for standpoints which       (different) from his own and does not allow personal hostility to enter into       should be a conflict of ideas. He anticipates the points put forward by his opponent and deals with them methodically. He attempts to present a     (consist) case,      rather, a piece of reasoning free from self-contradiction. He realizes that the       (accept) conclusions must be supported by adequate evidence. He knows how to sum up the various points that arise in the course of the debate.
