B.发言提纲是有效发言的基础。

通过写发言提纲，你可以确保你的思想是相关联的，你的思路从一点谈到另一点，你的讲话结构是连贯的。

通常，准备讲演你可以采用两种提纲方式：

详细准备提纲和简单发言提纲。

在准备发言提纲中，应该写出你的特定目的及中心思想，并以连贯的方式确定主要观点和次要观点，发言提纲应该由简要的提要组成，这些提要在你讲话时能够给予你一些帮助。

发言提纲还应该包括帮助你记忆的重点词或重点短语。

在写发言提纲时，可采用准备提纲的模式，尽可能使你的发言提纲简要，同时，要确保提纲清晰，易于辨认。

B．能源和人类利益有着双重关系。

人类历史发展长河中，由于利用能源成本低廉，人们主要关注能源和人类安康关系中有利的一面。

然而，过去一百年以来人口以空前速度增长，引起了能源需求的激增，同时，人均工业能源需求亦急剧增长。

因此，能源利用所需成本越来越高，无论是外延成本还是内涵成本。

一方面，能源资源加速减少，能源供应所需投入越来越高；

另一方面，相比之下，外延成本更加令人忧虑，原因是能源利用严重威胁大众健康和安全，不断破坏全球生态系统，并可能引发大规模军事冲突。
