在《容易犯错的形容词从句》一文里，知道形容词从句总是跟在被修饰的名词（即先行词）后面。例如： ① Any change which causes the formation of new matters is a chemical change.（在主句主语的名词之后） ② Plastics is an important material which is widely used in industry.（在主句补足语名词之后） ③ It has certain features that are easily recognised.（在主句宾语名词之后） 在下列情况下，形容词从句和所修饰的名词隔开： ㈠被介词短语隔开，如： ④ Magnets work through lines of force that extend between the two ends of the magnet. ⑤ A molecule may be defined as the smallest particle of matter that can exist without changing its nature. ④里的形容词从句和先行词lines被介词短语of force 分离。⑤里的却被另一个介词短语of matter隔开。 ㈡被分词短语隔开，如： ⑥ There is no method known to medical science today that can effectively cure cancer. ⑥里的形容词从句和先行词method之间被过去分词短语 known to medical science today隔开。 上述两种隔离情况可以理解，也被接受。 另外还有一种分隔情况，也偶尔见到，特别在科技英语中，但这种离异法，值得商榷。 |
