Despite some lower court expressions to the contrary，the more prevalent view is that loading，stowing and discharging are "non-delegable" obligations of the carrier of goods by sea. In consequence，while it may be permissible to transfer the responsibility for paying for loading，stowing and discharging to the shipper or consignee (e.g. by inserting an "FIOST" clause in the bill of lading)，this or any other clauses which purport to also transfer the liability for fault or negligence in the conduct of these operations from the carrier to cargo are null and void，because they relieve or lessen the carrier's obligations otherwise than as permitted by the Act. This position is well-founded，given the fundamental purpose of the Rules and the national statutes of protecting shippers and consignees against the superior bargaining power of carriers. While acceptable in charterparties，which are contracts of private carriage，such clauses are rightly set aside by courts in carriage under bills of lading.69. According to this passage，"FIOST" clause in the bill of lading is ______.A. not accepted by courtsB. acceptable in courtsC. a non-delegable clause in the bill of ladingD. incorporated in the bill of lading to avoid superior bargaining by the carrier against thereceiver70. The prevalent view is that ______.A. the carrier may validly delegate its responsibility for discharging the cargo to another partyB. whether the carrier may validly delegate its responsibility for discharging the cargo to anotherparty is still in disputeC. it is not necessary to consider whether the carrier may validly delegate its responsibility fordischarging the cargo to another partyD. the carrier may not validly delegate its responsibility for discharging the cargo to another party71. In the eyes of law，an "FIOST" clause in the bill of lading ______.A. does not transfer the responsibility for paying for loading，stowing and discharging to theshipper or consigneeB. has nothing to do with the responsibility of the carrierC. relieves or lessens the carrier's obligations otherwise than as permitted by the ActD. imposes more obligations to the carrier than as permitted by the Act72. It can be inferred that the author______the opinion that the carrier may validly delegate itsresponsibility for discharging the cargo to another party.A. supportsB. does not supportC. has not indicated whether he supports or notD. has no interest in discussing第二组：When SEA EMPRESS was two or three cables from the Channel entrance，the pilot saw from the changing aspect of the Outer Leading Lights that there was a set to the east. He ordered a course change of 5° to port. The vessel，which was now closing with the Mid Channel Rocks Light Buoy，started to turn to port. The pilot saw the Outer Leading Lights close and then open to the east as the bows entered the channel. The Buoy was very close to starboard and the pilot now saw that the fixed red and fixed white lights of the Outer Leading Lights，the ones indicating the east side of the deepest water in the Channel entrance，were also open to the east.After the bows had passed the Middle Channel Rocks Light to starboard there was a shuddering vibration，then a sound from the deck below of liquid being forced under pressure，accompanied by a strong smell of oil. The helmsman reported that the vessel was not steering and the pilot ordered 'full astern'. The Chief Officer recorded this order and the vessel's position，which was 1.4 cables northwest of Middle Channel Rocks Light. SEA EMPRESS，which was trimming by the head and taking a starboard list，continued to run ahead as the main engine was on full astern. There were further main engine movements and the vessel finally lost all way after she grounded again in a position about 3.3 cables south-by-west of the Mill Bay Buoy. The main engine was put to 'stop'. SEA EMPRESS was by this time significantly trimmed by the head and had taken an 18° list to starboard with the starboard fore part of the deck awash and was heading in a northwesterly direction.73. The course of SEA EMPRESS，when entering the Channel entrance，was most likely in a directionof ______.A. NorthB. EastC. SouthD. West74.“The pilot saw the Outer Leading Lights close and then open to the east as the bows entered thechannel”. This indicates that ______.A. the front Leading Light appeared to move to the left of the rear Leading LightB. the rear Leading Light appeared to move to the right of the front Leading LightC. the rear Leading Light appeared to move to the east of the front Leading LightD. the front Leading Light appeared to move to the east of the rear Leading Light75. When SEA EMPRESS was grounded the second time，her smallest freeboard was on her ______.A. port side before mid sectionB. port side after mid sectionC. starboard side before mid sectionD. starboard side after mid section76. A conclusion can be drawn from this passage that SEA EMPRESS was grounded at about ______hours (LT).A. 0200B. 0900C. 1900D. 2200 三．中译英（共2题，请将答案写在答题纸上）77.就你方要求一油轮外档傍靠并跨过我轮卸货，及租船人同意你轮傍靠一事声明如下：根据租船合同傍靠条款，只有当装卸我船货物时才可傍靠，并且当船长认为此傍靠和装卸货作业不安全时，有权拒绝。

Movement of the bridgetransmitter results in electrical imbalance and current flow to the motor in the control box. The motor drives, through a flexible coupling, a screw shaft, causing it to turn. A screw block on the shaft is moved and in turn moves the floating lever to which a control rod is attached. The control rod operates the slipper ring or swash plate of the variable delivery pump. A cut-off leverconnected to the moving tiller will bring the floating lever pivot and the lever into line at right angles to the screw shaft axis. At this point the rudder angle will match the bridge lever angle and the pumping action will stop. For local manual control, the electrical control is switched off and a small hand-wheel is connected to the screw shaft. Rotation of the hand-wheel will move thefloating lever and bring about rudder movement as desired.75.This passage is mainly on ______.A. the electrical remote control of main enginesB. the electrical control equipment of steering gearsC. the bridge remote control of main enginesD. the control box assembly in steering gear compartment76.The advantage of the control equipment is ______.A. that the transmitter is on the bridgeB. that local manual control can be achieved.C. that remote control cab be achieved.D. simple in construction and reliable in operation.77.The function of the cut-off lever is ______.A. to provide electrical signalB. to provide feed-backC. to provide local manual controlD. to provide right rudder angle78.Another name for the “swash plate” in the variable delivery pump is ______.A. tiltable discB. gravity discC. distributing discD. catch plate三、中译英（共2题，请将答案写在答题纸上）79.当船舶短途航行时，在《油类记录簿》上应每周记录残油（油渣）的数量。

First, it is fed through a heater and next through a centrifuge for purification. It may then pass through a cooler, before being discharged to the steam-heated heavy oil service tanks. Two of these are usually fitted and they are used alternately. One tank is in use, while the other is being filled. These tanks are heated to a moderate temperature and self-closing drain valves are fitted to remove any water or sludge which may settle out. The oil is drawn from the service tank in use by pumps and discharged at low pressure to the fuel oil heater. These pumps should be in duplicate. A relief valve on the pumps will return excess pressure to the system. A viscosity regulator is fitted at the heater discharge, through which the oil will pass. This automatically controls the temperature of the oil fuel leaving the heater to maintain its viscosity within close limits. A by-pass must be fitted to the viscosity regulator. The oil is then discharged through a fine strainer to the main engine fuel pump suctions. A pressure control valve is fitted in thesystem and excess oil returned either to the heavy oil service tanks or to a balancing tank.A diesel fuel tank is included in the system with its discharge to the primary pump suctionsthrough a change-over valve. By operating this valve the engine may be operated on diesel oil.Change-over should be very gradual to allow temperatures in the system to stabilize. During this period, the excess oil will return either to the heavy oil service tanks or a balancing tank. After it has been pumped from the DO tanks, where it is stored, the diesel oil passes through a centrifuge for purification before entering the diesel oil tank.75.The word “these” in line 4 probably means ______.A. HO tanksB. a heater and a centrifugeC. a heater and a coolerD. heavy oil service tanks76.How is change over from heavy oil to diesel oil carried out?A. Step by stepB. Hand over handC. Step for stepD. Quickly77.Where are self-closing drain valves fitted?A. HO tanksB. Heavy oil service tanksC. Balancing tankD. Centrifuge78.Which of the following statements is true according to this passage?A. Two heavy oil service tanks are used meanwhile.B.“Heater” mentioned in this passage is only used to heat heavy oil.C. Two pumps are fitted, which draw oil from the service tank in use.D. Diesel oil passes to the primary pump, and then through a change-over valve.三、中译英（共2题，请将答案写在答题纸上）79.所有费用由船东支付。

Each cargo compartment is individually connected to the smoke detecting cabinet with small bore piping and, by a suction fan mounted on the wheelhouse roof, samples of the air in each cargo space are continually drawn up to the smoke detecting cabinet and discharged into the wheelhouse or the atmosphere through a diverting valve. Thus smoke from a fire in any cargo space can be immediately detected.69. The CO 2 fire extinguishing system may combine with to detect fire in the early stage of firedevelopment.A. a smoke detecting systemB. a wheelhouseC. a cargo compartmentD.a crew‟s cabin70. The function of the smoke sampling system is ______.A. to analyze smoke componentsB. to detect fire in the early stageC. to prevent the wheelhouse from catching a fireD. to ventilate each cargo compartment71. According to this paragraph, which of the following statements is true?A. The smoke sampling system consists of the CO 2 fire extinguishing installation and smokedetecting cabinet.B. The smoke detecting cabinet is located on the wheelhouse roof.C. The suction fan draws samples of the air from cargo spaces.D. Samples of the air flow into the detecting cabinet at regular intervals.72. Which of the following devices does the smoke sampling system consist of?(1)fire extinguishing installation (2) smoke detecting chamber (3) wheelhouse(4) cargo compartment (5) suction fan (6) diverting valveA.（1）、（2）、（5）B. （2）、（4）、（5）C. （3）、（4）、（6）D. （2）、（5）、（6）第二组：Governing prime movers, particularly diesel engines, require careful consideration. The cyclic variations of a diesel cycle can be passed i nto the governor drive if it is too …stiff‟. That is, the cyclicvibrations will be imposed on the internal gearing etc. inside the governor housing. To prevent this, some form of damper should be used on the drive into the governor. The mounting point for the governor should be rigid; a vibration mounting would soon downgrade even the best of governors. Chain or belt drives should be avoided as far as possible, as slapping of the belt or chain produces speed variations causing malfunction of the governor. Similarly the drive from the end of the camshaft is subject to torsional vibrations, and governors should not be located at that point. They should be located as close as practicable to the fuel pumps, thereby limiting the mass/inertia of operating linkage. In all cases, the governor should be matched to the engine requirements in terms of droop, load limiting, response time etc. On large engines there is an inertial resistance to acceleration within the masses of reciprocating and rotating elements of the engine, so that during acceleration fuel could be released to the cylinders at a faster rate than efficient combustion can burn it. In an attempt to compensate for this, and to maintain acceptable combustion during acceleration, a tapping from the scavenge space may be taken and the pressure used to regulate the rate of fuel released to the engine. This process is incorporated into the governor operating system so that the governor releases a quantity of fuel commensurate with the increase in air pressure in the scavenge space.(during deceleration the problem is not so great, as excess air can be tolerated far more easily than can the incomplete combustion associated with insufficient air.)73. This passage is mainly about __.A. mounting the governorsB. the scavenge pressure limit to the governorC. A and BD. how the governor regulates the fuel index74. The drive to the governor ___.A. should be rigidB. should use damperC. should use chains or beltsD. should be from the end of the cam shaft75. The governor should be mounted close to the fuel pumps ___.A. for limiting the inertia effectB. for limiting the loadC. to ensure speed droopD. to cut down the cost76. It can be inferred that with scavenge pressure limit ___.A. the engine can be accelerated rapidlyB. the engine can be decelerated rapidlyC. the governor will supply fuel oil efficientlyD. the combustion will be more complete三、中译英（共2题，请将答案写在答题纸上）77.PSC官员如果发现大量的临时修理，例如管路卡箍和水泥堵漏箱，则表明船舶不愿意进行永久性修理。

When used to extinguish class B fire, extinguisher should be turned upside down and cover firesmoothly.A. a soda and acidB. a foamC. a CO2D. a dry powder第二组Where routine maintenance is concerned, the governor should be checked regularly for adequate lubrication. The operating range is usually quite small, giving a tendency for them to wear over limited areas. Then a sudden and larger change in speed than normal may carry the governor onto a ridge of debris or gummy oil deposit so that it may stick at that point. To restrict this problem as far as possible, the governor pivots, slide, etc. should be cleaned and well lubricated whenever possible. It should be born in mind that the governor structure is such that, were the spring to fracture in any way, the flyweights would be able to move outwards and shut the engine down. The connections from the governor to the fuel racks should be designed in such a way that the governor can both increase and decrease the fuel within the bounds of some hand setting; i.e. the governor can adjust the fuel settings but cannot release more fuel to the engine than is dictated by some predetermined value set by the engine operator.To overcome the above limitations of the CF governor, …servo governors‟ have been developed. These use the power of hydraulics to pump the heavier fuel rack systems associated with larger engines into the desired posit ion. This …powered‟ operation is rapidly and accurately achieved, and the hydraulic flow can be either electrically or mechanically controlled. The speed sensing can be done by a tachometer arrangement that can be set to the desired speed, and on sensing any variation a solenoid operated flow valve allows pressurized hydraulic flow into a servo system of pistons/plungers which resets the rack positions. Although this system is quite effective, more mechanically controlled governors are fitted to larger engines. These use the principle of the CF governor, i.e. fly weights acting against spring pressure, but instead of the slide working directly onto the fuel racks it simply regulates the flow of hydraulic fluid to servo pistons controlling the rack positions. this system therefore has the proven reliability and sensitivity of the small CF governor and yet develops quite a large governor effort through the hydraulic fluid.73.Which of the following is the reason that the governor discussed sticks?A. The governor is not sensitive normally.B. It is because of wear in normal working range.C. The change of speed is too small .D. All of the above are true.74.If the spring fractured，______.A. the fly weights would fracture tooB. the speed would be greatly increasedC. the operator would set the valueD. the fuel would be cut off75.The “servo governors” ______.A. can produce a large forceB. are mechanically controlledC. use flyweights to sense the speedD. All of the following are true.76.The second paragraph is mainly about ______.A. hydraulic powerB. CF governorsC. advanced governors in stead of CF governorD. electrical or mechanical hydraulic flow三、中译英（共2题，请将答案写在答题纸上）77.PSC官员在检查机械处所时，如果发现阀手轮丢失、水和油长期渗漏的迹象或机器底座的延伸性锈蚀，则说明船舶对系统的维护不能令人满意。
