一、請將下列英文譯為中文：（25 分）The handling characteristics of a ship fitted with a variable pitch propeller are significantlydifferent from those with a fixed blade propeller. Variable pitch propulsion systems haveadvantages since a diesel engine so fitted does not have to be stopped and restarted to goastern, and almost infinite choice of speeds is available. Further, you can go asternindefinitely which isn’t possible for a turbine driven ship, and unlike a conventional motorship, you can change the direction of propulsion repeatedly without concerning aboutexhausting the supply of starting air.
