你做的幻灯片只是观众视觉上的辅助。

Your slide show is just a visual aid.

幻灯片在图表展示或视觉辅助方面十分好用，可以对重点起到补充作用。但很多人使幻灯片成了演讲的中心，而非演讲者本人和传递的信息。

It can be a useful tool for showing graphs or visual AIDS to complement important points, but too many people make it the focus of their presentations, in place of themselves and their actual message.

使用幻灯片或其他辅助手段会增加时长——稍微提前一点结束比延长时间要好。

Using a flip chart or other visual AIDS also adds to the time. Remember - it is better to finish slightly early than to overrun.
