5. 除此之外,介詞on, in, with, at, of, to等引導的介詞短語,不定式符號to,分詞結構也可以作為拆分點。
例如:Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned, orderly, systematic, and dispassioned manner that natural scientists use for the study of natural phenomena.(35詞,2003年62題)
拆分本句的信號詞有:which, in, that。注意本句出現的兩個and連接的是幾個詞匯,并非句子,所以不用作為拆分點。因此這個句子可以拆分成四個片段。拆分后句子的總結構是:
(1)主干Social science is that branch of intellectual enquiry;
(2)定語從句which seeks to study humans and their endeavors;
(3)方式狀語in the same reasoned, orderly, systematic, and dispassioned manner;
(4)定語從句that natural scientists use for the study of natural phenomena。
