4. It's not all about the work. "The best presentations draw people in and make an emotional connection between the speaker and the audience," says O'Brien. "You'll be much more engaging and memorable if you tell a funny story or share a favorite quote, talk a bit about yourself and reveal a little of who you are outside the office."

4. 不要只谈工作。“最出色的陈述能让听众沉浸其中，在演讲者与听众之间建立一种情感上的联系，”奥布莱恩说。“如果你讲一个有趣的故事，或者分享一句最喜欢的名言，谈一谈一下自己，展示一下办公室之外的自己是什么样子，会令你更具有吸引力，给听众留下更深的印象。”

You don't want to overdo this, of course, but handled right, it can be riveting. For proof, check out Sheryl Sandberg's famous 2010 TED talk (the one that led to her writing Lean In). Sandberg's frankness and self-deprecating humor carries it -- and without a PowerPoint slide in sight.

当然，一定要掌握分寸，只要处理得当，一定能吸引听众注意。谢丽尔•桑德伯格著名的2010年TED演讲【（正是这次演讲让她决定写《向前一步》（Lean In）这本书】就是最好的证据。桑德伯格的坦率和自嘲式的幽默给所有人留下了深刻印象——而她在演讲过程中没有使用任何幻灯片。
