全国海船船员11新规则考试（轮机部（轮机英语））试题及答案（一） 第一部分 船舶主推进装置 第一章 船舶动力装置概述 1.Marine power plant is a plant that propels a( )vessel. A.submarine B.suspending C.ship-borne D.waterborne 答案：D 解析：marine power plant：船舶动力装置；propel：驱动；submarine：水下的；ship-borne：船 上的；waterborne：水上的，水运的【译文】：船舶动力装置是驱动水上船舶的装置。 2.( )is the prime important characteristic for a marine power plant. A.Reliability B.Fuel economy C.Low maintenance D.Long life 答案：A 解析：prime：首位的，首要的；characteristic：特性，性能；reliability：可靠性【译文】：可靠性是船舶动力装置的首要特征。 3.There are four main types of marine power plants: ( ). A.the diesel engine, the steam turbine, the gasoline engine and the marine nuclear plant B.the diesel engine, the steam turbine, the gas turbine and the marine nuclear plant C.the diesel engine, the internal combustion engine, the external combustion engine and the marine nuclear plant D.the diesel engine, the steam turbine, the exhaust turbine and the marine nuclear plant 答案：B 解析：marine power plant：船舶动力装置；steam turbine：蒸汽轮机；gas tur-bine：燃气轮机 ；nuclear plant：核动力装置；internal combustion engine：内燃机；external combustion engine：外燃机【译文】：船舶动力装置主要有四种：柴油机动力装置、蒸汽轮机动力装置、燃气轮机动力装 置和核动力装置。 4.Gas turbines differ from steam turbines in that( ). A.steam rather than gas is used to turn a shaft B.vapor rather than gas is used to turn a shaft C.the former uses gas to turn a shaft D.the latter uses gas to turn a shaft 答案：C 解析：gas turbine：燃气轮机；differ from：与…不同；steam turbine：蒸汽轮机【译文】：燃气轮机与蒸汽轮机的不同之处在于前者是由燃气驱动轴的。 5.The diesel engine is similar to the gasoline engine in that( ). A.both of them are ignited by compressed air B.both of them are the forms of external combustion engines C.both of them have spark plugs D.the power is developed by the piston in the cylinder 答案：D 解析：similar to…：与…相似，相似于…；spark plug：火花塞【译文】：柴油机与汽油机的相似点在于都是由气缸内活塞产生功率的。 6.The reason why more and more the large merchant vessels are being powered by medium-speed diesel engines is( ). A.they operate between 150 and 450 r/min B.they are connected to the propeller by gearing C.th
