A good practice when giving any presentation, impromptu or not, is to decide what your main point is going to be.

Explanation:

Only after deciding what the main point is going to be can a speaker construct his/her speech, be it a long or a short one. Since every speech should have at least three parts (introduction, body, and conclusion), the main idea will help determine what to address in each of these parts. Of course, from the main idea it is possible to derive some smaller topics to be developed, but they should never lose their connection to the central point in discussion. In summary, knowing what he/she truthfully intends to talk about will help the speaker to structure and develop the speech properly. Study the example below:

-Main idea: defend a vegetarian lifestyle;

-Introduction: establish a relationship between diseases and the consumption of meat;

-Body: detail how a vegetarian lifestyle can be an alternative by referring to health studies and even telling a personal experience;

-Conclusion: repeat the main idea in a short manner, inviting the audience to live a healthier life from now on.

explanation:

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

analyze the effectiveness of this excerpt. how does it function within the speech as a whole? how does the structure of the excerpt to convey the speech's purpose and key points? support your argument with evidence from the speech. (10 points)
