【答案】:C

解析:本题考察STCW公约的英文缩写及全称。STCW是《InternationalConventiononStandardsofTraining,CertificationandWatchkeepingforSeafarers》(《海员培训、发证和值班标准国际公约》)的缩写,是海员培训、发证和值班标准的核心公约。选项ASOLAS为《国际海上人命安全公约》(SafetyofLifeatSea);选项BMARPOL为《国际防止船舶造成污染公约》(InternationalConventionforthePreventionofPollutionfromShips);选项DCOLREG是《国际避碰规则》(InternationalRegulationsforPreventingCollisionsatSea),均不符合题意。6、船舶航行日志(VoyageLog)中,无需记录的内容是?

A.船舶航速、航向及船位

B.能见度、气象条件及设备运行状态

C.货物装卸量及舱位调整情况

D.主机、舵机等关键设备的操作指令

【答案】:C

解析:本题考察航海日志记录规范。航行日志主要记录船舶航行过程中的动态(航速、航向、船位、气象、设备状态、操纵指令等)。选项C货物装卸量属于大副或理货报告范畴,非航行日志内容;选项A、B、D均为航行日志核心记录内容,故排除。7、Inshipmaneuveringterminology,theterm'sway'specificallydescribestheship'smovementinwhichdirection?A.Alongthelongitudinalaxis(foreandaft)B.Perpendiculartothelongitudinalaxis(sideways)C.Verticaldirection(upanddown)D.Diagonallyacrosstheship'slength

A.Alongthelongitudinalaxis(foreandaft)

B.Perpendiculartothelongitudinalaxis(sideways)

C.Verticaldirection(upanddown)

D.Diagonallyacrosstheship'slength

【答案】:B

解析:本题考察船舶操纵术语中横荡(sway)的定义。在船舶操纵学中,sway特指船舶沿垂直于首尾线(纵轴)方向的横向运动。选项A描述的是纵荡(surge),选项C为垂荡(heave),选项D为斜向运动,均不符合sway的定义。因此正确答案为B。8、Whatdoestheradiocall'Mayday,Mayday,Mayday'indicateinmaritimecommunication?

A.Generalsafetywarning

B.Emergencydistresssignal

C.Vessel'sroutinepositionreport

D.Navigationinstruction

【答案】:B

解析:本题考察国际遇险通信规则。'Mayday'是国际通用的遇险求救信号,由船舶、飞机等遇险时连续发送,用于请求紧急援助。选项A'Generalsafetywarning'(一般安全警告)通常使用'Pan-Pan'信号;选项C'Vessel'sroutinepositionreport'(船舶常规船位报告)使用'NavigationalMessage'格式;选项D'Navigationinstruction'(航行指令)不属于求救信号范畴。因此正确答案为B。9、AccordingtotheInternationalRegulationsforPreventingCollisionsatSea(COLREGs),whichvesselisthe'stand-on'vesselinacrossingsituation?

A.Thevesselonthestarboardside

B.Thevesselontheportside

C.Thegive-wayvessel

D.Thefastervessel

【答案】:B

解析:本题考察交叉相遇局面中直航船(stand-onvessel)的定义。根据COLREGs,交叉相遇时,“让路船(give-wayvessel)”位于直航船的右舷,直航船则位于让路船的左舷(portside),因此B正确。A为让路船(右舷船需给左舷船让路);C“give-wayvessel”是让路船而非直航船;D速度快慢非判断直航/让路的依据。10、Whennavigatinginanarrowchannel,whichofthefollowingisaprimaryconcernforthehelmsman?

A.Maintainingaconstantspeedregardlessoftrafficdensity

B.Avoidingexcessiveuseoftheenginethrottletopreventpropellerwash

C.Minimizingthevessel'swaketoavoiddisturbingnearbyships

D.Alloftheaboveareimportantconsiderations

【答案】:D

解析:本题考察狭水道航行的操纵要点。选项A错误,安全航速需根据交通密度调整;选项B正确,螺旋桨尾流(wash)可能导致附近船舶失控或偏移;选项C正确,减小船尾流(wake)可避免影响周围小船或航道设施;选项D(以上均正确)为正确答案,因为狭水道航行需综合考虑速度、螺旋桨影响及尾流干扰等因素。11、Whichinstrumentisusedtomeasurethedirectionofthewindrelativetotheship'sheading?

A.Stand-onvessel

B.Give-wayvessel

C.Overtakingvessel

D.Crossingvessel

【答案】:B

解析:本题考察国际避碰规则(COLREGs)中船舶行动责任的知识点。根据COLREGs,让路船(Give-wayvessel)的核心义务是尽早采取行动以避免与他船碰撞,而直航船(Stand-onvessel)仅在必要时才需采取行动。选项A的直航船无主动避让义务;选项C的追越船需在追越过程中承担让路责任,但题干为一般性场景,“Give-wayvessel”是最直接的责任主体;选项D的交叉船需根据具体航向判断,并非统一承担避让责任。因此正确答案为B。13、WhichofthefollowingisaprimaryresponsibilityoftheMasterduringnavigationwatchaccordingtoSTCWConvention?

C.Soundthedangersignalandimmediatelychangecoursetostarboardtoavoidcollision

D.Proceedatfullspeedandovertakeassoonaspossibletominimizethepassagetime

【答案】:A

解析:本题考察狭水道追越规则(COLREGsRule9)。追越时应保持在被追越船右舷(starboardside),并在追越开始前发出追越信号(如声号或VHF广播)。选项B错误,追越船应在被追越船右舷而非左舷;选项C错误,“危险信号”(如一短一长一短声)仅用于狭水道航行时的特定警告,非追越专用;选项D错误,盲目全速追越易引发碰撞风险。选项A符合“右舷追越+提前发信号”的核心规则,故正确。17、WhichofthefollowingisacorerequirementoftheInternationalSafetyManagement(ISM)Code?

A.ThemastershallensuretheshipoperateswithavalidSafetyManagementSystem(SMS)

B.Theshipmustcarryaminimumof10lifejacketsforcrewmembers

C.Thevessel'sradioequipmentmustpassannualinspections

D.Theship'screwmustattendmonthlysafetydrills

【答案】:A

解析:本题考察ISM规则核心要求。ISM规则要求建立并维护有效的安全管理体系(SMS),船长负责确保SMS的合规运行。B选项救生衣数量、C选项无线电年检、D选项月度演练均非ISM规则强制要求(属于具体操作细节)。因此正确答案为A。18、Inradarnavigation,whatdoes'TrueMotionDisplay(TMD)'show?

A.Relativemotionoftargetwithrespecttoownship

B.Truemotionoftargetwithrespecttofixedreference

C.Onlythetarget'sheadingandspeed

D.Trueheadingofthetargetonly

【答案】:B

解析:本题考察雷达显示模式的概念。正确答案为B,‘TrueMotionDisplay’(真运动显示)以真北为固定参考系,显示目标相对于地理坐标的实际运动轨迹。A选项‘Relativemotion’(相对运动显示)为RMD(RelativeMotionDisplay)的定义;C选项‘Onlyheadingandspeed’(仅航向和航速)描述过于片面,TMD需显示运动轨迹;D选项‘Trueheadingonly’(仅真航向)忽略了航速信息,不符合雷达标绘的基本要求。19、AccordingtoSTCWConvention,theMastermayauthorizeanofficertomaintainthenavigationwatchinwhichofthefollowingsituations?

A.Whenthevisibilityisreducedduetoheavyfog

B.Whentheofficerhassufficientexperienceinallweatherconditions

C.Whenthevesselisinanopenseawithgoodvisibilityandnonearbyvessels

D.Whentheshipisinanarrowchannelwithclearwaterdepth

【答案】:C

解析:本题考察STCW公约中航行值班授权规则。根据STCW公约A-VI/1部分,船长可授权驾驶员保持航行值班的前提是:船舶处于安全水域、能见度良好、周围无航行障碍物或其他船舶。选项A错误,因能见度不良(如大雾)时驾驶员瞭望受限,船长不得授权;选项B仅强调经验,忽略环境安全要求;选项D错误,狭水道航行需船长亲自监督,因航道复杂易发生碰撞。选项C符合“开阔水域、能见度良好、无附近船舶”的安全条件,故正确。20、Whichisthemostimmediatedistresssignaltobetransmittedwhenashipisindangerofsinking?

A.Morsecode'SOS'

B.VHFChannel16

C.Telexmessagetonearestportauthority

D.Satelliteemergencyalert(e.g.,Inmarsat-C)

【答案】:B

解析:本题考察船舶遇险信号的优先级。VHFChannel16(156.8MHz)是国际遇险与安全频道,船舶遇险时应立即在该频道发送清晰、简短的遇险信号(如“Mayday,Mayday,Mayday”),是最即时、最直接的海上遇险通信方式。A选项“Morsecode'SOS'”需依赖特定无线电设备(如GMDSS设备),操作复杂且响应延迟;C选项“Telexmessage”(电传)传输速度慢,不适合紧急情况;D选项“Satelliteemergencyalert”(卫星紧急警报)依赖卫星覆盖且需配合其他设备,无法替代即时VHF通信。因此正确答案为B。21、WhatistheEnglishtermforthedevicethatemitsacontinuoussoundsignaltoindicatethepresenceoftheship,suchasinfoggyconditions?

A.Fogsignal

B.SART

C.AIStransponder

D.EPIRB

【答案】:A

解析:本题考察船舶设备功能。正确答案为A,“Fogsignal”(雾号)在能见度低时(如雾中)发出持续声音信号;B选项SART(搜救雷达应答器)用于被雷达探测后反射定位;C选项AIS(自动识别系统)用于船舶间信息交换;D选项EPIRB(应急无线电示位标)用于遇险信号发射,均为错误选项。22、WhatisthecorrectChinesetranslationforthemarineweatherterm'Lowpressuresystem'?

A.Highpressuresystem

B.Lowpressuresystem

C.Frontalsystem

D.Cyclonicsystem

【答案】:B

解析:本题考察气象术语翻译。“Lowpressuresystem”直译为“低气压系统”,对应选项B。选项A(高压系统)为“Highpressuresystem”;选项C(锋面系统)为“Frontalsystem”,与低压无关;选项D(气旋系统)虽常伴随低压,但“Lowpressuresystem”的标准翻译为“低压系统”,故正确答案为B。23、UnderCOLREGs,whennavigatinginanarrowchannel,theMastershouldensuretheship______.

A.Maintainssafespeedandkeepstothestarboardsideofthechannel

B.Proceedsatmaximumspeedtominimizenavigationtime

C.Reliessolelyonradarforlookoutinrestrictedvisibility

D.Positionfixing

【答案】:B

解析:本题考察船舶操纵英语指令的理解。选项A'Setanddrift'指水流偏航和漂移,是描述船舶位置偏差的术语,非指令;选项C'Speedcontrol'仅涉及速度调节,与保持航向无关;选项D'Positionfixing'是定位操作,非航向指令。正确答案B'Steadyheading'意为“保持航向”,符合船长维持恒向航行的指令需求。52、Whichtermreferstothespeedatwhichavesselcanbestoppedandturnedinagivendistance,consideringprevailingseaconditionsandnavigationalhazards?

A.Safespeed

B.Minimumspeed

C.Maximumspeed

D.Steamingspeed

【答案】:A

解析:本题考察安全航速的定义。根据《国际海上避碰规则》及航海实践,安全航速(Safespeed)是指船舶在当时环境和情况下,能够采取适当而有效的避碰行动,并能在适合当时环境和情况的距离内把船停住的速度。B选项“Minimumspeed”(最低速度)无行业定义,仅指理论下限;C选项“Maximumspeed”(最高速度)是船舶设计的最大航行速度,未考虑安全因素;D选项“Steamingspeed”(航行速度)是船舶通常航行时的速度,不涉及安全停船距离。因此正确答案为A。53、Whichterminnavigationreferstothespeedofavesselrelativetotheseabedorland?

A.Boatspeed

B.Groundspeed

C.Relativespeed

D.Trawlspeed

【答案】:B

解析:本题考察航海术语的英文表达。选项B正确,“Groundspeed”指对地速度(船相对于海底/陆地的速度)。选项A(Boatspeed)指船速(相对于水的速度);选项C(Relativespeed)指相对速度(两物体间的速度差);选项D(Trawlspeed)指拖网速度,与题意无关。因此正确答案为B。54、Upondiscoveringafireintheengineroom,whichistheFIRSTactiontheMastershouldtakeaccordingtoSOLASfiresafetyregulations?

A.Oneprolongedblastfollowedbytwoshortblasts

B.Oneshortblast

C.Twoprolongedblasts

D.Threeshortblasts

【答案】:A

解析:本题考察船舶在能见度不良时的声号规则。根据《国际避碰规则》,机动船在能见度不良(如雾中)航行时,应每2分钟鸣放一长两短声(选项A),以表明本船动态。选项B(一短声)通常用于互见中船舶避让的信号;选项C(两长声)无标准使用场景;选项D(三短声)是引航船在船首方向有引航员时的特定信号,均不符合题意。故正确答案为A。58、Whichofthefollowingbestdefines'safespeed'accordingtotheInternationalRegulationsforPreventingCollisionsatSea(COLREGs)?

A.
