这段内容的学术语言基本符合要求，但需要注意以下几点：
句子之间缺少连接词，可以使用逗号或者分号进行连接。
在第二句话中，“which should be defined or supported by relevant references”可以改为“which will be defined or supported by relevant references”，强调将会在后面提供相关定义或支持材料。
在第三句话中，“it provides a detailed analysis of the interactions among these spaces”可以改为“finally, a detailed analysis of the interactions among these spaces is provided”。使用主动语态更加规范。
改写后：
After conducting a comprehensive literature review, we have identified three common categories of metaphor: nature metaphor, war metaphor, and human metaphor. This section firstly highlights the unidirectional mapping between source domain and target domain using active voice; secondly, it demonstrates the multidirectional mapping in four mental spaces, which will be defined or supported by relevant references; finally, a detailed analysis of the interactions among these spaces is provided.
