例23　Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned, orderly, systematic manner that natural scientists use for the study of natural phenomenona.

【结构分析】这句话是复杂的连环定语从句，主干是Social science is that branch of intellectual enquiry，后面加上定语从句which seeks to study humans and their endeavors in the same reasoned, orderly, systematic manner，后面再加上定语从句that natural scientists use for the study of natural phenomenona。

【亮点回放】这句话是很棒的连环的定语从句，最后的定语从句是the same后面加上that的定语从句，不能加which，是个固定搭配，还表示一种比较关系，很经典。

【核心词汇】

intellectual enquiry　知识学科

endeavors　行为

reasoned, orderly, systematic manner　有逻辑，有秩序，系统化的方式

study of natural phenomenona　研究自然现象

【参考译文】社会学是一种知识分支，跟自然学家研究自然现象一样，用同样的有逻辑的，有秩序的，系统化的方式研究人类和人类的行为习惯。
