航海英语练习

第一组：Major coast radio stations all over the world transmit，at regular intervals and in code，weather information for ships within range. Weather information consists of ten parts，of which ships usually make use of three，that is，warning，synoptic situation and forecast. With weather information，mariners are able to keep away from disastrous weather at sea and reduce the danger a great deal. As terrible weather is predicted，ships can take precautions beforehand，by delaying the voyage or seeking shelter in a safe place. If there is a high sea or a long swell，they can take some measures to safeguard the cargo and the ship.89 Weather information for ships is usually transmitted by coast radio stations ___.A. any time of the dayB. at fixed timeC. in different languagesD. in some parts of the world90 Coast radio stations generally provide weather information for ships ___. I. in code, II. In a certain language, III. in written formA. IB. I + IIC. IID. I + II + III91 Weather information usually tells people something about weather _____.A. afterwardsB. in advanceC. at the same timeD. when there’s bad weath er92 Of the following, ______ is not the way for ships to keep away from bad weather.A. delaying voyageB. staying in portC. speeding up and running awayD. pumping out ballast water第二组：Generally a ship’s mo tion contains components of pitch and roll simultaneously. Both these motions may cause the ship to head first to one side of its course, and then to the other. This is called yawing. When waves are sufficiently large, the whole vessel maybe moved vertically up and down; this is called heave. Large waves passing under the ship from one side impart a side-to-side motion known as sway. The movement of the whole ship ahead and astern is called surge. If the ship is under present at any moment and at any particular place on the surface of the sea are complex, because they are the product of large numbers of different wave motions, of different sizes and moving in different directions, so also the motion of the ship is complex, and is the product of components of each of the six ship motions.93 What does yawing mean in the passage? I. Ship’s angular motion about vertical axis, II. The ship first moves to one side of its course and then to the other, III. Ship’sangular motion about longitudinal axis.A. IB. IIC. IIID. I or II94 Which one of the followings about surge is incorrect?A. surge is the ship’s movement ahead and astern along longitudinal axisB. surge is caused by duty of ficers’ improper manoeuvringC. surge may cause ship’s speed increasedD. surge may cause ship’s speed decreased95 Which of the following is the characteristics of waves? I. Waves move in different direction, II. Waves are of different sizes and on the surface of the sea, III. Wavespresent at any moment.A. IB. I + IIC. IIID. I + II + III96 The best title for this passage may be ___A. ship’s motionsB. waves and its impactC. waves’ characteristicsD. ship’s rolling and pitching答案A ship’s head up, or un-stabilised, radar display has the ship’s heading marker fixed at 000°, at the top of the screen.All targets, fixed or moving, then move relative to the ship’s position in the center of the screen and the heading marker. As the ship moves through the water, fixed target appear to track down the screen on a reciprocal heading at the speed the ship is moving and when the ship alters course targets appear to rotate in the opposite direction to that of the ship, so targets appear t o move on the radar screen while the ship’s heading remains fixed. The coating on a radar display is designed to allow a certain amount of afterglow（余辉）of targets, which in the ship’s head up mode causes smearing（拖尾）and may make the identification of smaller targets difficult.In addition, when targets, particularly large landmasses, are in close proximity interference occurs, which can further inhibit the detection of small targets.1.When radar is set to ship’s head up display, all fixed targets displayed on the screen willappear to ______.A. track down the screen on a reciprocal heading at the speed the ship is movingB. rotate in the same direction as the ship rotatesC. make the identification of smaller targets difficultD. allow a certain amount of afterglow of targets2.In the ship’s head up mode, if the ship rotates starboard-wise all fixed targets on the screenwill appear to ______.A. rotate starboard-wiseB. rotate port-wiseC. remain stationaryD. move on a reciprocal heading at the speed the ship is moving3.Afterglow of targets will ______.A.have the ship’s heading marker fixed at 000°B. cause the fixed targets to remain fixedC. inhibit the detection of small targetsD. make the identification of smaller targets difficult4.It can be concluded that the instrument referred to in this passage is most likely a/an ______.A. ordinary radarB. ARPAC. specially designed radarD. radar which is out of order第二组The Chief Officer, or First Mate as he is often called, is the Master’s chief officer and head of the Deck Department. He is assisted by a Second Officer(Mate) and a Third Officer(Mate), and sometimes a Fourth Officer(Mate). Several companies employ a First Officer as well as a Chief Officer. The Deck Department also includes a Boatswain (Bosun) and a Carpenter，both petty officers，and a number of ratings. These made up of Able Seamen (AB)，Ordinary Seamen (OS) and a middle grade known as Efficient Deck Hands (EDH). There are other grades of seamen. On some ships Navigating Cadets are carried for training purposes. The Chief Engineer is head of the Engine Department.He is assisted by a Second，Third，Fourth and sometimes Fifth Engineer.An Electrical Officer may also be carried.The engine room petty officers are the Storekeeper and Donkeyman. On tankers there is also a Pumpman. He is also a petty officer. The engine room ratings are Firemen and Greasers. There may also be Engineer Cadets. The Catering Department is under the Chief Steward. It is divided into a saloon and galley section. The former is headed by the Second Steward，the latter by the Ship's Cook.They are both usually petty officers. They are assisted by several stewards and cooks，and by a number of junior ratings. The Radio Department often consists of only one man: the Radio Officer.On ships where continuous radio watches are kept there may be three radio officers: a Chief，Second and Third.5.________ is not a petty officer.A. BoatswainB. Second StewardC. Radio OfficerD. Storekeeper6.EDH is rank which is higher than________.A. Second StewardB. ABC. OSD. Chief Engineer7.Storekeeper belong to ________.A. Deck DeptB. Engine DeptC. Catering DeptD. Radio Dept8.There are ________ departments on bard a big ship according to the passage.A. twoB. threeC. fourD. five答案。
