Unit 1

Outlines are essential to effective speeches.By outlining, you make sure that related ideas are together, that your thoughts flow from one to another, and that the structure of your speech is coherent. You will probably use two kinds of outlines for your speeches--the detailed preparation outline and the brief speaking outline.

In a preparation outline, you should state your specific purpose and central idea, and identify main points and sub--points using a consistent pattern. The speaking outline should consist of brief notes to help you while you deliver the speech. It should contain key words or phrases to bolster your memory. In making up your speaking outline, follow the same visual framework used in your preparation outline. Keep the speaking outline as brief as possible and be sure it is plainly legible.

發言提綱是有效發言的基礎。通過寫發言提綱,你可以確保你的想法是關聯的,你的思路從一點談到另一點,你的講話結構是連貫的,通常準備演講你可以采用兩種提綱方式:詳細準備提綱和簡單發言提綱。

在準備提綱中,應該寫出你的特定目的及中心思想,并以連貫的方式確定主要觀點和次要觀點。發言提綱應該由簡要的提要組成,這些提要在你講話時能夠給你一些幫助。發言提綱還應包括幫助你記憶的重點詞或重點短語。在寫發言提綱時,可采用準備提綱的模式,盡可能使你的發言提綱簡要,同時,要確保提綱清晰、易于辨認。

當你發表學術演講時,首先要做好充分的準備;其次,你演講的主要觀點要明確,層次要清楚。演講時,語速不要過快,語言要清晰。不要總是在讀你準備好的稿子。最后,你應該經??匆幌履愕穆牨?。這樣,一方面你對你的聽眾表示尊重,另一方面,你可以更順利地進行你的演講。

Before you deliver an academic speech, you should, first of al, get well prepared for it. Then, you should make your major points clear in your speech, and your speech should be well organized. When speaking, you should not speak too fast, and your language should be explicit. Don’t always read the notes you prepared beforehand. From time to time, you should look at your audience. On one hand, you can show your respect to your audience, and on the other hand, you will be able to go on with your speech more smoothly.
