简报时，许多讲者都会提出陈述的论点(statement)，却没有提供充分的例子(examples)与理由(reasons)来支持所陈述的东西，如此一来听众便无法得到足够或具体的资讯、甚至被说服。
简报时，你可以利用例子与理由来支持自己的论点。提供例子与理由时通常有两个选择，一个是提供短的例子与理由(brief examples and reasons)，一个是提供长的例子与理由 (extended examples and reasons)。其中短的例子与理由通常包含在一句话中，例如下列句子中划底线处即为短的例子与理由：
（例子）
Warm paint colors, like yellow or pink, can give your home a cozy feeling.
温暖的油漆颜色，例如黄色或粉红色，可以给您的家舒适的感觉。
（理由）
I refuse to work with Ben, because he is lazy, irresponsible, and never on time.
我拒绝跟Ben一起工作，因为他懒惰、不负责任，而且从来不准时。
长的例子与理由通常需要另外用一句或几句话才能说完，例如以下段落中划底线处即为长的例子与理由：

When going to a job interview, it is important to wear your best outfit. For example, you should wear a suit made from the same cloth that consists of at least a jacket and trousers.

Don’t wear brand new shoes, extreme styles or casual footwear.
工作面试时，穿上你最好的服装很重要。例如，你应该穿由相同一块布料制成的一套西装，至少包含一件外套和一件裤子。你还应该戴一条图案简单和色彩鲜艳的领带。此外，你鞋子的色彩和风格应该要与你的衣服协调。不要穿全新、风格极端和休闲的鞋子。
