看到這題,首先要聯想到船舶主推進系統的核心物理功能:產生推力 (Thrust) 以提供船舶前進 (Ahead) 與倒車 (Astern) 的操縱能力。接著,從輪機長實務管理的角度切入,推進系統的目標還必須包含:高可靠度 (Reliability)、燃油經濟性 (Fuel efficiency) 以及符合國際海事環保法規 (Environmental compliance)。務必嚴格遵守題目『以英文作答』的要求,並使用精確的輪機英文術語。
小題 (二)
There are two fundamental types of pumps, namely the kinetic type and the positive-displacement type. Please itemize the pumps characterized as the kinetic and the positive-displacement types.

考生看到此題應立刻想到船用泵浦的兩大分類:動能型(依靠葉輪賦予流體動能)與容積型(依靠機械容積變化擠壓流體)。作答時,除了直接列出泵浦名稱,建議將容積型進一步細分為往復式(Reciprocating)與旋轉式(Rotary),並簡要補充各泵浦的實務應用,能展現更深厚的輪機英文與實務素養。
