Listen carefully and answer the following questions. A couple had been married for 30 years and were celebrating their 60th birthdays which fell on the same day. During the celebration a fairy appeared and said that because they had been such a loving couple for 30 years, she would give them one wish each. The wife wanted to travel around the world. The fairy waved her hand .Boom! She had the ticket in her hand. Next It was the husbands turn. He paused for a moment, then said shyly, ”Well, Id like to have a woman 30 years younger than me.” The fairy picked up her hand and Boom! He was ninety.Questions: 1. What was going on in the story? 2. Who appeared during the celebration? 3. What could the fairy do ? 4. Did they realize their wishes ?Part II. In this part you will hear ten statements.

Id like to look at the instruction books, designing plans and other relative data of the main electric equipment before I take over the ship. (c) 2Q: What stores havent been brought on board?(C)Part IV. In this part you will hear three passages. Listen carefully and do the exercises according to what you hear.Passage 1:A pump is a machine used to raise liquids from a low point to a high point. The pumping action can be achieved in various ways according to the type of pump employed. A piping system on a ship will consist of suction piping, a pump and discharge piping. The system is arranged to provide a positive pressure at some point and discharge the liquid. The pump provides the energy to develop the pressure and overcome any losses in the system.Exercise I: Answer the following questions 1. What is a pump?2. What does a piping system on a ship consist of?3. On what can a pump depend to achieve its pumping action ?Exercise II: Complete the following sentences according to what you hear:1. The pumping action can be achieved in various ways according to the type of the pump employed.2. The pump provides the energy to develop the pressure and overcome any losses in the system.Passage 2:The displacement pumping action is achieved by the reduction and increase in volume of a space causing the liquid to be moved. The axial-flow pumps use a screw propeller to axially accelerate the liquid. Centrifugal pumps depend on centrifugal force for operation. The liquid enters the center of the impeller and flow radiantly out, its speed being increased by the impeller rotation. The high speed is largely converted into pressure in the pump casing . An impeller is mounted on a rotating shaft.Exercise: Make proper choices according to what you hear: 1. By what is the displacement pumping action achieved? (c) 2. What do the axial-flow pumps use to accelerate the liquid? (b) 3. On what do the centrifugal pumps depend for operation? (d)Passage 3:Pumps are used on many occasions on board and different pumps play different roles. They are suitable for delivering different quantities of liquid at the different pressure. In general, the reciprocating pumps are suitable for delivering small quantities at high pressure; the centrifugal pumps are more used 31Q: What are they doing?(A)4.W: I am exhausted.M: We have been working almost three weeks without a break.

Most are designed to carry cargo, but a few still carry passengers. Cargo ships can be divided into two basic types. One type carries dry cargo, the other carries liquid cargo. Some types of the ships are bulk-carrier, dry cargo ship, freighter, salvage vessel, reefer, Ro-Ro vessel, tanker-container ship, container ship, full container ship, partial container ship, combination ship, tanker, passenger liner and so on.Exercise I: Answer the following questions :1.

The deck department also includes a boatswain and a carpenter, both petty officers, and a number of ratings.The chief engineer is head of 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 donkey-man. On oil tankers there is also pump-man. He is also a petty officer. The engine room ratings are fireman and greasers.

The compressed air must be supplied in the correct sequence according to the direction require.2. The air compressor may be driven directly by the engine or from a separate power source, Passage 3:The reversing system should perform several functions. First, it must stop the fuel to the cylinders when the engine stops. Second, when the engine is put in the ahead position, the fuel pumps should be in a position to supply fuel, and then the starting air supply should be activated. Third, when maneuvering from the ahead to the astern position, the fuel must be stopped and the cams moved to the astern position. Last, the compressed air is admitted to the engine to turn it in the astern direction.Exercise: Listen to the following sentences and write them down :1. First, it must stop the fuel to the cylinders when the engine stops.2. Second, when the engine is put in the ahead position, the fuel pumps should be in a position to supply fuel.3. Last, the compressed air is admitted to the engine to turn it in the astern direction. Lesson Eight PumpsPart I . StoryJack had gone to the university to study history, but at the end of his first year, his history professor failed him in his examinations, and he was told that he would have to leave the university. However, his father decided that he would go to see the professor to urge him to let Jack continue his studies the following year.“Hes a good boy,” said Jacks father, “ and if you let him pass this time, Im sure hell improve a lot next year and pass the examinations at the end of it really well.”“No, no, thats quite impossible!” replied the professor immediately. “Do you know last month I asked him when Napoleon had died, and he didnt know!”“Please, sir, give him another chance,” said Jacks father. “You see, Im afraid we dont take any newspapers in our house, so none of us even knew that Napoleon was ill.”Questions: 1.

They carry both dry cargo and liquid cargo. Dry bulk cargo is carried in bulk carriers. Container ships are the most modern type of dry cargo carriers. They carry containers of standard dimensions. Fruit, meat and dairy product are carried in refrigerated ships. Oil tankers are the most common type of liquid cargo carrier. In comparison with cargo vessels, passenger ships are fewer in number and type. Cruise ships are another type of passenger vessel. Ferries are the most common type of passenger vessel. Many of them are also designed to carry vehicles.Exercise : Make proper choices according to what you hear1. Which of the following vessels belongs to passenger ships?(b)2.

She swims to the bottom and pulls him out. When the doctor hearsof this, he immediately orders her to be discharged from the hospital because he thinks she now seems mentally stable. He goes to tell Mary the news. “Mary, I have good news and bad news. The good news is youre being discharged because you were able to save the life of another patient. I think youve regained your news is that Jim ,the patient you saved, hanged himself with his bathrobe belt in the bathroom.
