1 Historical review: Some topics are better understood if a brief historical review of the topic is presented to lead into the discussion of the moment. Such topics might include "a biographical sketch of a war hero," "an upcoming execution of a convicted criminal," or "drugs and the younger generation." Obviously there are many, many more topics that could be introduced by reviewing the history of the topic before the writer gets down to the nitty gritty of his paper. It is important that the historical review be brief so that it does not take over the paper.
Final comments: This speech is about you, (meaning, you obviously know the material well)---but, here's a strong reminder--you still need to practice. You want to be confident enough to be able to establish and maintain lots of eye contact throughout your presentation. This is not a reading assignment. Looking down too much will ruin your credibility. Think about your presentation as though you are having a conversation with the class. Stay connected with your audience, smile, speak at a conversational rate (not too fast, and not too slow) and sound as though you are enjoying yourself. Stand up straight, (don't lean on the podium, or slouch), keep your chin up and keep your voice at an audible level. Gesture occasionally and move deliberately. It is acceptable to stand quietly behind the podium instead of moving nervously about. No hats and no gum. Clothing should be comfortable and modest. Hairstyles should not cover your face. You might want to pin your hair back if it has the habit of falling in your face. You want to keep your hands away from your face and clothing while speaking. These movements are distracting and unnecessary.
Elliptical Clauses are grammatically incomplete in the sense that they are missing either the relative pronoun (dependent word) that normally introduces such a clause or something from the predicate in the second part of a comparison. The missing parts of the elliptical clause can be guessed from the context and most readers are not aware that anything is missing. In fact, elliptical clauses are regarded as both useful and correct, even in formal prose, because they are often elegant, efficient means of expression. (The omitted words are noted in brackets below).
