听力原文： Ensuring the safety of passengers and aircraft is a major concern at airports. Security personnel operate metal detectors and X-ray machines that screen baggage for possible weapons or illegal substances. Security personnel also require that each passenger show photo identification before entering an aircraft. Many areas of an airport, especially those areas that contain critical equipment, are protected by security personnel and are off-limits to the public.

In the wake of the September 11, 2001, terrorist attacks in the United States, airport security became the responsibility of the federal government. The United States Congress enacted the Aviation and Transportation Security Act in response to the attacks, which bad exposed a number of weaknesses in airport and airline security. The new law expanded the number of baggage screeners, imposed standards for their training, and made them federal employees for a period of time. Beginning in January 2002, it required that all passenger luggage, including checked luggage, be screened. By the end of 2002, all checked luggage was to he put through special explosives-detecting devices. The law increased the number of armed federal air officials flying on domestic flights and required international airlines to turn over advance copies of their passenger lists to U.S. Customs officials for background checks to screen out suspected terrorists.

A collision between an aircraft and one or more birds is termed a bird-strike. Pilots sometimes record a birdstrike while at cruising altitudes, but most of them happen when an aircraft is relatively close to the ground, usually in proximity to an airport and during the circling, descent to land or take-off phases of a flight.

Birdstrikes may cause significant damage to an aircraft and/or, if the birds are ingested into a jet engine, a significant and sudden loss of power. If this were to happen during take-off or initial climb of a fully loaded passenger aircraft the results could be catastrophic—loss of the aircraft and the lives of those on board. Any bird is a potential hazard to aircraft and this is especially true as bird numbers and bird size increase.

Unfortunately airports themselves can be attractive to birds—rodents, insects and other small animals are a food source often found in flat grassed areas such as the runway strips. Even so, this problem can be reduced by careful habitat management or bird harassment techniques practised by airport maintenance and safety personnel.

Care needs to be taken by local authorities in deciding the location of rubbish tips, or when permitting other land uses that may be attractive to birds in this way. Of course these effects cannot always be anticipated with certainty since birds such as gulls have been recorded as travelling 50 ki-lometres or more from their roosting area to an attractive food source.

Local authority planning schemes often apply strict controls on developments such as abattoirs, cattle feed lots, grain handling, piggeries, canals and marina developments, fish farms, and suchlike. In most cases these uses will not be permitted without a full environmental study. That study should be required to deal with the question of likely bird hazards if the proposed location is in proximity to an airport.

In some instances it may be necessary to consider ways of managing a particular land use in order to reduce its attractiveness to birds, for example the adoption of land-fill measures at garbage tips, or enclosed rather than open-air activity. Specialist ornithological opinion may be necessary. In such cases it may not be possible to implement immediate changes in land use, but this should not inhibit the adoption of long-term measures which are designed to achieve this. Summary:

Unfortunately airports themselves can be attractive to birds—rodents, insects and other small animals are a food source often found in flat grassed areas such as the runway strips. Even so, this problem can be reduced by careful habitat management or bird harassment techniques practised by airport maintenance and safety personnel.

Further problems may arise because the airport is located on bird migration routes. These may have existed prior to the airport site selection—but may not have been taken into account because the problem was not understood at the time—or have only been recently established because the birds have found an attractive new food source. Care needs to be taken by local authorities in deciding the location of rubbish tips, or when permitting other land uses that may be attractive to birds in this way. Of course these effects cannot always be anticipated with certainty since birds such as gulls have been recorded as travelling 50 kilometres or more from their roosting area to an attractive food source.

Agricultural uses may be thought desirable because they are compatible with high levels of noise exposure, but they can have an adverse effect on air-craft operations if birds are attracted during seeding or crop cultivation. Birds may also be attracted to pig farms where garbage is used as fodder. Even tree plantings can present a hazard if the species provides an attractive food source or nesting habitat.

Local authority planning schemes often apply strict controls on developments such as abattoirs, cattle feed lots, grain handling, piggeries, canals and marina developments, fish farms, and suchlike. In most cases these uses will not be permitted without a full environmental study.

There are two main things that make aircraft engineering difficult, the need to make every component as reliable as possible and the need to build everything as light as possible. The fact that an airplane is up in the air and cannot stop if anything goes wrong, makes it perhaps a matter of life or death that its performance is absolutely dependable.

Given a certain power of engine, and consequently a certain fuel consumption, there is a practical limit to the total weight of an aircraft that can be made to fly. Out of that weight as much as possible is wanted for fuel, radio navigational instruments, passenger seats, or freight room, and of course, the passengers or freight themselves. So the structure of the aircraft has to be as small and light as safety and efficiency will allow." The designer must calculate the normal load that each part will bear. This specialist is called the "stress man". He takes account of any unusual stress that may be put on the part as a precaution against errors in manufacture, accidental damage, etc.

The stress man's calculations go to the designer of the part, and he must make it as strong as the stress man says is necessary. One or two samples are always tested to prove that they are as strong as the designer intended. Each separate part is tested, then a whole assembly—for example, a complete wing, and finally the whole aeroplane. When a new type of aeroplane is being made, normally only one of the first three made will be flown. Two will be destroyed on the ground in structural tests. The third one will be tested in the air.

When a plane has passed all the tests it can get a government certificate of airworthiness, without which it is illegal to fly, except for test flying.

Making the working parts reliable is as difficult as making the structure strong enough. The flying controls, the electrical equipment, the fire precautions, etc. must not only be light in weight, but must work both at high altitudes where the temperature may be below freezing point and in the hot air of an airfield in the tropics.

To solve all these problems the aircraft industry has a large number of research workers, with elaborate laboratories and test houses, and new materials to give the best strength in relation to weight are constantly being tested.

The two main requirements of aircraft design are______.

A．speed and cost

B．reliability and passenger comfort

C．lightness and dependability

D．ability to stay up in the air and reliability

Mason also holds around $2 million of aircraft spares which are included within inventory. Mason sells the aircraft spares to amateur flying associations. Aircraft spares which are not sold after three years are scrapped. Approximately a quarter of this value is made up of specialist equipment taken out of aircraft when it was replaced by newer or more advanced equipment. Such specialist equipment is transferred from non-current assets to inventory without adjustment, and continue to be recognised at amortised cost. Which of the following summarises the key audit concern arising from the matter described?

A、Accuracy, valuation and allocation of non-current assets

B、Completeness of non-current assets

C、Existence of inventory

D、Accuracy, valuation and allocation of inventory
