贾政冷笑道：“倒休提这话。我养了这不肖的孽障，已不孝；教训他一番，又有众人护持；不如趁今日一发勒死了，以绝将来之患!”说着，便要绳索来勒死。王夫人连忙抱住哭道：“老爷虽然应当管教儿子，也要看夫妻分上。我如今已将五十岁的人，只有这个孽障，必定苦苦的以他为法，我也不敢深劝。今日越发要他死，岂不是有意绝我。既要勒死他，快拿绳子来先勒死我，再勒死他。我们娘儿们不敢含怨，到底在阴司里得个依靠。”说毕，爬在宝玉身上大哭起来。贾政听了此话，不觉长叹一声，向椅上坐了，泪如雨下。

Above all know your audience and match what you say to their needs．Creating your presentation with your audience in mind will assure that your audience will follow you．If your presentation doesn't appeal to your audience-no matter how well you have developed your presentation--your presentation will fall on deaf ears．This leads us to the next rule:Know your material thoroughly．Your material needs to be second nature to you．Practice and rehearse your presentation with friends,in front of a mirror,and with colleagues．If you are speaking in a second language,make sure that you record yourself and listen to a number of times before going to practice with a native speaker(if possible).
Remember that you are an actor when presenting．Make sure that not only your physical appearance is appropriate to the occasion,but also the tone you use is well chosen．If your topic is serious,be solemn．However,it's always a good idea to begin your presentation with an ice-breaker．Don't worry about making friends,rather lead the audience through your materials in a calm and relaxed manner．Speak slowly and clearly,and remember to address everyone in the audience-even the person the farthest away from you.
To achieve the above goals follow these tips when giving your presentation:
●Speak with conviction．Believe what you are saying and you will persuade your audience．
●Do not read from notes．Referring to notes is fine,but do so only briefly.
●Maintain eye contact with your audience．Making direct eye contact with individuals will help them feel as if they are participating in your presentation.
●Bring handouts．Don't just use a PowerPoint presentation．Provide audience members with handouts of the most important materials so they can keep your most
important takeaways in mind.
●Know when to stop．This cannot be underestimated．You need to make your case,but continuing for too long will only ensure that the audience forgets what you have said.

Why should you know when to stop?

A.Because you need res
B.Because audience may fall aslee
C.Because you may be tired for talking too lon
D.Because it can make audience remember what you sai
