Transformation of natural

With the increasing research on global resource and environment, studies on the transformation of natural resource-based cities have become a focus in the academia as a cosmopolitan problem.

随着全球资源环境问题研究的不断深入，资源型城市转型问题的研究成为一项世界性的研究课题。

For example, most transformation steps that involve the reading of natural language documents, regardless of the level of formality in them, are typically not suited to MDA-style automation.

例如，大部分涉及自然语言文档的阅读的转换步骤(不管它们中形式的级别)，不适合mda式样的自动化。

The world at the start of the 21st Century is also the result of what we call the Great Acceleration - the most rapid transformation of the human relationship with the natural world in history.

世界开始21世纪也是我们称为‘大加速’的结果，这是历史上最快的一次人类与自然关系的转变。
