于是张良至军门见樊哙。樊哙曰：“今日之事何如？”良曰：“甚急！今者项庄拔剑舞，其意常在沛公也。”哙曰：“此迫矣！臣请入，与之同命。”哙即带剑拥盾入军门。交戟之卫士欲止不内，樊哙侧其盾以撞，卫士仆地，哙遂入，披帷西向立，瞋目视项王，头发上指，目眦尽裂。项王按剑而跽曰：“客何为者？”张良曰：“沛公之参乘樊哙者也。”项王曰：“壮士，赐之卮酒。”则与斗卮酒。哙拜谢，起，立而饮之。项王曰：“赐之彘肩。”则与一生彘肩。樊哙覆其盾于地，加彘肩上，拔剑切而啖之。项王曰：“壮士！能复饮乎？”樊哙曰：“臣死且不避，卮酒安足辞！夫秦王有虎狼之心，杀人如不能举，刑人如恐不胜，天下皆叛之。怀王与诸将约曰：‘先破秦入咸阳者王之。’今沛公先破秦入咸阳，毫毛不敢有所近，封闭宫室，还军霸上，以待大王来。故遣将守关者，备他盗出入与非常也。劳苦而功高如此，未有封侯之赏，而听细说，欲诛有功之人。此亡秦之续耳，窃为大王不取也。项王未有以应，曰：“坐。”樊哙从良坐。坐须臾，沛公起如厕，因招樊哙出。

沛公已出，项王使都尉陈平召沛公。沛公曰：“今者出，未辞也，为之奈何？”樊哙曰：“大行不顾细谨，大礼不辞小让。如今人方为刀俎，我为鱼肉，何辞为？”于是遂去。……

     The Importance of Setting Speech Goals

     A speech is a wonderful opportunity to inform, persuade or entertain. The best speeches often take

on a combination of all three of these components. However, before you can go about the writing of a

great speech, it is important to set goals. Goals keep you, your speech and your audience focused.

     What a goal is

     In the context of a speech, a goal is the purpose of the speech, and what it hopes to accomplish. For

example, the goal of a eulogy (颂歌) might be to celebrate the life of a loved one. The goal of a speech

at a political gathering would be to inform the crowd about the political position of a candidate and

persuade them to vote and campaign for the candidate in question.

     Why a goal is important

     Without a goal, a speech is without direction. The goal informs the structure and content of the speech. For example, if a speech's goal is to convince people that smoking is bad for them, the speech will be

structured with persuasive arguments to back up the goal. A speech with a goal of informing the audience will keep the information fair and factual.

     A goal is incredibly important to the speech's ability to connect with an audience. If the speaker is

unaware of the goal of the speech, the audience will likely be unaware as well. This severely reduces the

effectiveness of the message.

     Aside from informing the audience of the content and structure, a speech's goal drives the speaker to

greater heights. If a speaker is asked to speak on a specific subject, but never establishes the goal, they

won't know where to start in the research, organizing and writing of the speech.

___________________________________

     If you have been charged with (被委以) delivering a speech, establishing a goal can seem difficult at

first. There are several things to take into consideration. First, think about who you will be speaking to.

The demographic (人口统计) of your audience will likely determine whether you will be able to persuade them, or whether they will be able to sit through. Second, think about the topic itself. If the topic is

something controversial(有争议的), it may be worth your while to consider an informative approach to

present both sides of the issue. Finally, consider your resources. A speech with an informative or

persuasive goal usually requires a great deal of research, and sometimes takes more time to write.

A. a speech will lose its direction without a goal

B. a speech goal can help keep the audience aware of the speech

C. a speech goal can help the speaker know about the research, organizing and writing
