8.Directions: In the following article, so
In the following article, some sentences have been removeD．For Questions 41—45, choose the most suitable one from the listA—G to fit into each of the numbered blank. There are two extra choices, which do not fit in any of the gaps. Mark your answers onANSWER SHEET 1. (10 points) The place is a lovely meadow surrounded by deep woods on a hilltop overlooking a beautiful lake in theCatskill Mountains 120 miles from New York. It is quarter past eight in the morning, and you are about to commute to your office in the city. Yet there is no paved highway nearer than fifteen miles, and it is fifty to a railroad station. 41) __________________________________________. The aircraft, looking oddly like a horizontal electric fan, drones toward you. When the pilot is directly overhead, all forward movement of the machine ceases and it descends vertically until the cabin door is within a foot of the grounD．On the machine’s gray side is painted HelicopterExpress to New York. The door opens and you step inside. Fifty minutes later the helicopter bus hovers over a midtown New York building, descends slowly to alight on a roof space some sixty yards square. You go into the building, take the elevator to the street below, and walk half a block to your office. Not quite an hour has elapsed since you drank your morning coffee in your home. 42) ______________________________________. In the air age of tomorrow, the manufacture, sale, and upkeep of the direct—lift machine will become a billion—dollar industry just as the automobile industry. There will be many startling changes in our way of life. 43) ________________________________________________.A．cheap, swift helicopter bus service will ferry these people to and from their work. Suburbs will include ten thousand or more square miles. Real estate values will come within the reach of average incomes, and the people will literally return to the good earth. 44) _________________________________________________.But the short haul of less than 1000 miles is equally the task of the helicopter, which can do it with the greatest efficiency. Express and air mail will be carried from the airports to final destination by helicopter. There will be a direct—lift machine service to take airliner passengers from the airport to the city in a few minutes. There will be special delivery of perishable food to your door. The winter growth of fresh vegetables such as beans and tomatoes, celery and lettuce, in the warm South and the Far West has been hitherto restricted because of cost and time or transportation to market. The airline and helicopter freight service will speed such healthy foods to the ends of the nation. 45) __________________________________________________________.. [A] Most important is that hundreds of thousands of people can return to the health and beauty of the countryside. Millions of acres of hitherto inaccessible land will be developed with small homes for medium-or low-income groups. [B]And a new type of architecture-perhaps a house with a flat roof and a pleasantly designed helicopter hangar to one side of it, so that you have only to wheel the machine a few feet to take off. [C]Does this sound like a fantasy imagined by science fiction writers? If so, I can assure you, as a practical aeronautical engineer, that such a trip is neither fantastic nor impractical. I am convinced that a helicopter bus service is not only practicable but, in fact, inevitable. [D] Hence our eating habits will change perhaps more than we realize. Strawberries in January, as it were, available for all. The airline and helicopter freight service render all this possible. [E] Private and bus helicopters will make possible vacations at seashore or mountain for countless thousands. The helicopter will destroy space for millions of people. Nothing is more delightful than touring in a helicopter. To hover and fill one’s eyes with an enchanting vista is to bring joy to the soul. [F] Now you hear a low hum, and over the horizon appears a flying machine. You press the button of a box nearby and a radio signal flashes to the machine. [G] Long-distance transportation of passengers and freight over land and sea will definitely remain the job for the large airplane.
