30. Electricity is the phenomenon associated with positively and negatively particles charged of matter at rest and in motion, either individually or in great numbers. 改错(答案中指出particles charged 这有问题),为什么?此句如何理解?

词的顺序颠倒了，改成 positively and negatively (charged particles) of matter 就好了。因为positively and negatively是副词，不能修辞名词particles，只能修辞动词分词charged。positively and negatively charged particles of matter：带正电和负电的物质粒子电是单个或大量带正电和负电的物质粒子在静止和运动状态，伴随产生的现象。
