                        美 [ˌiː.kəˈnɑː.mɪ.kəl]                    
                    
                    
                    
                 
                
             
                        
            
                将“economical”分解为“eco”和“nomical”。想象“eco”代表环保,意味着节省资源;“nomical”听起来像“nominal”,暗示着低成本。结合起来,记忆为:环保的、低成本的,这样就能联想到“economical”这个单词的意思是经济的、节省的。
