五、請將下列專業英文翻譯成中文。（20 分）
Controllable pitch propellers are normally fitted to a flanged tail shaft as the operating mechanism is housed in the propeller boss. As its name implies, it is possible to alter the pitch of this type of propeller to change ship speed or to adjust to the prevailing resistance conditions. This change in pitch is effected by rotating the blades about their vertical axes, either by hydraulic or mechanical means. A shaft generator can be driven at constant speed while allowing at the same time a change of ship’s speed through the propeller. Since it is normally possible to reverse the pitch completely, this type of propeller is used with a unidirectional engine to give full ahead or astern thrust, when maneuvering.

本題為輪機專業英文翻譯，核心主題是「可控螺距螺槳 (Controllable Pitch Propeller, CPP)」。作答時首重專業術語的準確度，如 propeller boss (螺槳轂)、pitch (螺距)、shaft generator (軸發電機)、unidirectional engine (單向運轉主機) 等。翻譯時應先理清句子的因果與修飾關係，再以符合工程實務的中文語氣平順表達，避免生硬直譯。

【譯文】 可控螺距螺槳通常安裝於法蘭式艉軸上，其操作機構則收納於螺槳轂內。顧名思義，此類型螺槳可藉由改變螺距來調整船速，或適應船隻當下所面臨的阻力狀況。螺距之改變，係透過液壓或機械方式，使螺槳葉片繞其垂直軸旋轉來達成。其允許軸發電機以恆定轉速驅動，同時又能透過螺槳來改變船速。由於通常能將螺距完全反轉，此類型螺槳可搭配單向運轉主機使用，以便在操船時提供全速的正車或倒車推力。 【重點詞彙/句型】
