材料：
While berthed alongside in Tenerife，the cruise ship Arcadia was carrying out a lifeboat drill．One lifeboat was successfully launched and as it was being recovered，the winch hoisting it failed．The lifeboat was still connected to the falls and it dropped back into the sea. To investigate what had happened，the crew had to wind the falls back onto the winch drum．The lifeboat was disconnected while the crew tried to restart the winch．They were unsuccessful because of a fault on the hand crank cutout switch．
The crew then attempted to wind the falls back on using the hand crank，but because of the time and effort involved，the cutout switch was bypassed and power restored to speed up the operation．The crank handle was left in place． The winch was started．It began to turn and so too did the handle which hit one of the crew over the head．
The investigation found that the winch failed in the first place because the oil used in the winch gearbox was not one recommended．It was too viscose and would have prevented the coupling locking mechanism from operating correctly．
问题：
It was the fault on the ________ that caused the failure to recover the lift boat
A.crank handle
B.hand crank cutout switch
C.power system
D.falls
It was the ________ that hit the crewmember on his head．A.falls
B.hand crank cutout switch
C.crank handle
D.winch drum
The cause of the accident was that ________．A.the oil used in the winch gearbox was too viscose
B.the winch drum was connected with the falls
C.the life boat was too heavy
D.the bypass to the cutout switch was misused by the crew
The lesson from this accident is that ________．A.seafaring is not all about facing unforeseen situations
B.it is not necessary to wear hard hats to prevent sore heads
C.the wrong oil can not have serious repercussions
D.do not start lifeboat winch motors with the crank handle in place

材料：
Spark erosion is caused by a voltage discharge between the main bearing and journal surface. The cause of the potential is the development of a galvanic element between the ship’s hull, sea water, and the propeller shaft/crankshaft.
The oil film acts as a dielectric. The puncture voltage in the bearing depends on the thickness of the oil film. With increasing engine ratings, the specific load in the main bearing is increased. his will reduce the oil film thickness, and enable the discharge to take place at a lower voltage level.
Since the hydrodynamic oil film thickness varies through a rotation cycle, the discharge will take place at roughly the same instant during each rotation cycle, i.e. when the film thickness is at its minimum. The roughening will accordingly be concentrated in certain areas on the journal surface. In the early stages, the roughened areas can resemble pitting erosion. but later, as the roughness increases, the small craters will scrape off and pick up white metal-hence the silvery white appearance.
Therefore, to ensure protection against spark erosion, the potential level must be kept at maximum 80 mV, which is feasible today with a high efficiency earthing device. If an earthing device is installed, its effectiveness must be checked regularly. Spark erosion is only observed in main bearings and main bearing journals.
问题：
According to the paragraph one, a voltage between the main bearing and journal surface is produced by______.
A.propeller rotation
B.leakage from M/E electric control unit
C.a galvanic element
D.friction between the main bearing and journal surface
______engine ratings increase, the hydrodynamic oil film between the main bearing and journal surface is______.A.The lower/thinner
B.The higher/the thicker
C.The lower/thicker
D.The higher/thinner
When will the spark erosion take place on the journal surface during each rotation cycle?A.when the film thickness is at its minimum
B.when the film thickness is at its maximum
C.when the engine is on its compression stroke
D.when the engine is on its exhaust stroke
During the engine room watch keeping, which equipment must be noted to ensure protection against spark erosion?A.the antifouling plant
B.the earthing device
C.the main engine electric heating coils
D.the shaft generator
