简单的说, 现在分词和过去分词的用法区别主要在两点： 一是现在分词表示主动的意义,过去分词表示被动的意义. 例：（1）However,I am not interested in this subject at all. （2）He has some interesting plan. 二是现在分词所表示的动作未完成,过去分词多表示的动作多已完成. 例：（1）Children in many developing countries lack basic medical care. (2)We spend less on health care than most other developed nation.
