Passage 36 Wind and Its Effect
Wind has special significance in the handling of high-sided vessel such as car carriers. The effect will vary with the relative wind direction and the speed of the ship. Although wind force and direction can be estimated from information obtained from a variety, such as weather forecasts, VTS information, the ship’s own instrumentation and personal observation, local conditions can change rapidly and with little warning. Control of a ship can be easily lost during the passage of a squall暴风. There is an obvious need to understand how wind will affect your ship, and how this effect can be difficult to predict预测. For example, it might appear logical合乎常理的 that effect of wind on a tanker stopped in the water would cause the bow to swing摇晃，摆动 towards the wind. However, experience shows that a tanker in the water will usually lie with the wind forward of the beam rather than fine on the bow.

144. The effect of wind depends on all the following factors except .
A．the speed of the ship B．the relative wind direction
C．the height of the side of the ship D．the car loaded in the ship
Passage 37 Approach Channels
Approach channels allow a deep-draught ship to enter an otherwise shallow port and may provide many of the external factors that affect manoeuvring.
The width, depth and alignment 排成直线 of many approach channels are now subject to rigorous缜密的 analysis at the design stage so that they provide the minimum hazard to ships that move along them. They are designed for single or two way traffic and their width, depth and alignment are an optimized compromise 一种尽可能有效的折中方案between acceptable 可接受的marine risk on the one hand and economic acceptability (with regard to dredging 疏浚costs) on the other.

Passage 38 Anchoring Operations
When preparing to anchor, it is necessary to take to the forecastle a hammer, an oil can and some goggles. Before going to the forecastle, ask the engine room for power and water on deck. First, take off the covers from the hawse pipes and clear the spurling pipes, then, make sure that the windlass is out of gear and the brakes are on. Next, turn the windlass over slowly. While you are doing this, oil all the moving parts. On a steam windlass, the drain cocks must be opened and the water drained off before the cocks are closed again. After seeing that the gears are free to engage, put the windlass into gear. Then remove the devil’s claw and the compressor bar. On receiving the order to lower away, lower the anchor until it is clear of the hawse pipe. When you are sure that the weight of the anchor is held by the brake, take the windlass out of gear. When the order to let go the anchor is received, release the brake. As each shackle (27.5 metres) goes out, the forecastle bell is rung (1 ring for 1 shackle, 2 rings for 2 shackles etc.) When the anchor reaches the bottom, hoist the anchor ball or anchor lights. When enough cable has been paid out, apply the brake and put on the compressor bar. Then inform the engine room that power and water are finished with. Finally return all the gear.

A．make sure that the windlass is out of gear and the brakes are on B．turn the windlass over slowly C．release the brake D．put the windlass into gear 150. When enough cable has been paid out you should .

Passage 39. The decision to Use Great Circle Sailing
The decision as to whether or not to use great-circle sailing depends upon the condition. The saving in distance should be worth the additional effort, and of course the circle route cannot cross land, nor should it carry the vessel into dangerous waters. Composite sailing may save time and distance over the rhumb line track without leading the vessel into danger.
Since great-circles other than a meridian or the equator are curved lines whose true direction changes continually, the navigator does not attempt to follow it exactly. Rather, he selects a number of points along the great-circle, constructs rhumb lines between the points, and follows these rhumb lines from point to point.
153. A great-circle other than a meridian or the equator the corresponding rhumb line.
A．is shorter than B．is longer than
C．is equal to D．may be either shorter or longer than 154. The meridian and the equator are .
A．rhumb lines B．great-circles
C．both great-circles and rhumb lines D．neither great-circles nor rhumb lines
24
155. Composite sailing means .
A．the sailing along the great-circle for some time then the rhumb line for other time
B．the sailing along the great-circle C．the sailing along the rhumb
D．that the navigator selects a number of points along the great-circle, constructs rhumb lines between the points, and follows these rhumb lines from point to point 156. It is implied that .
A．great-circle sailing needs more efforts
B．great-circle sailing is easier than the rhumb line sailing
C．the great-circle routes usually cross land or carry the vessel into dangerous waters
D．few navigators have the ability to make the decision as to whether or not use great-circle sailing
Passage 40 The lateral Lights
Light rhythms格式 have no lateral 侧面的significance. Aids to navigation with lateral significance exhibit flashing, quick, occulting明暗的 or isophase等明暗光 light rhythms. Ordinarily, flashing lights (frequency not exceeding 30 flashes per minute ) will be used.
Preferred channel marks exhibit a composite group-flashing light rhythm of two flashes followed by a single flash.
Safe water marks show a white Morse code “A” rhythm ( a short flash followed by a long flash).
Isolated danger marks show a white flashing (2) rhythm ( two flashes repeated regularly).
Special marks show yellow lights and exhibit a flashing or fixed rhythm; however, a flashing rhythm is preferred.
For situations where lights require a distinct cautionary significance, as at sharp turns, sudden channel constrictions, wrecks or obstructions, quick flashing light rhythm will be used.
157. “A” rhythm is .
A．a short flash followed by a long flash B．two flashes repeated regularly
C．a fixed rhythm D．a quick flashing light rhythm
158. Preferred channel marks exhibit .

At other times, structures are usually marked with以??为标记 one or more fixed quick flashing white or red lights, visible for at least one
