                                 LARGEST AIRCRAFT IN THE WORLD

                                     

      We have lift-off. The world's largest aircraft has taken to the skies for the first time.The Airlander 10 spent nearly two hours in the air, having taken off from Cardington Airfield in Bedfordshire. During its flight, it reached 3,000 feet (914 meters) and performed a series of gentle turns all over a safe area.

      The aircraft is massive – as long as a football pitch and as tall as six double decker buses and capable of flying for up to five days. It was first developed for the US government as a long-rangesurveillance aircraft but was scrapped following cutbacks.

      Each one cost 25 million pounds and can carry heavier loads than jumbo jets while also producing less noise and emitting less pollution. The makers, Hybrid Air Vehicles, believe it‟s the future of aircraft, and that one day we'll be using them to get places.

      But we're a while away yet. The Airlander will need to clock up 200 hours‟ flying time before beingdeemed airworthy by aviation bodies. If it passes though, we can hope we'll all get some extra leg room.

Although the idea of reaching the language learner through as many of his senses as possible is by no means a new idea, modern technology provides so many means of doing so that at first the mind reels. The diagram shows the full panoply of stimuli which may reach the learner, from open circuit broadcasting through recordings of one kind or another, books and kits, to the range of human contacts he may make. Indeed, the resources made available to a learner in a learning system of this kind may be classed in the first instance as human and material. The most important human resource is the learning effort of the learner himself, in terms of time, intensity, efficiency and appropriateness of that effort. All other components in the system are evaluated by their effect upon these learning parameters. About these components, choose the correct alternative.

  • The teacher is an initiate who organizes, arranges and presents the material to be learned, checks on progress,provides feedback on performance and finds ways of overcoming learning blocks and difficulties, of building and maintaining motivation, fostering and controlling group dynamics.
  • The "native informants‟ are the members of the writing community who produce the behavior to which the learner is assimilating himself, or a corpus of linguistic artifacts on which the learner models his behavior, as well as the framework for direct conversational and pragmatic interaction.
  • The provision of all material resources employed in the working system, and its organization (engineers, technicians, writers, printers, publishers, secretaries, producers etc).
  • None of the above.
