钱博士pro向前+puls推挤+ion名词后缀→向前推挤⇒推进，推进力
词根pel-/pell-推挤，驱赶来自拉丁语，过去分词形式为puls-，末尾的s是动词反复形式或过去分词后缀-t的音变结果。常见单词push推就来源于puls-。参考单词propel推进。GRE红宝书pro向前, pul推动, sion－向前推－推动力
pro 前 + puls 源自pel, propel 推进；pro前 + pulse 脉搏，有脉搏是因为有心脏的推动
pro向前+puls跳动 ，推动+ion→向前推 →推进力词根记忆pro向前+ puls跳动，推动+ ion → 向前推 ⇒推进力方振宇词汇奥秘pro向前+puls驱使，促使+ion名词后缀→推进GRE难词记忆propulsion→propuls=to propel推进+ion→推进词根记忆pro向前+puls+ion=推进,动词,propel近义词 thrust刺force武力momentum势头movement活动impulsion冲动impetus推动力actuation推进driving force驱动力forward motion工作进程
