Since the Hawaiian Islands have never been connected to other landmasses, the great variety of plants in Hawaii must be a result of the long-distance dispersal of seeds, a process that requires both a method of transport and an equivalence between the ecology of the source area and that of the recipient area.
There is some dispute about the method of transport involved. Some biologists argue that ocean and air currents are responsible for the transport of plant seeds to Hawaii. Yet the results of flotation experiments and the low temperatures of air currents cast doubt on these hypotheses. More probable is bird transport, either externally, by accidental attachment of the seeds to feathers, or internally, by the swallowing of fruit and subsequent excretion of the seeds. While it is likely that fewer varieties of plant seeds have reached Hawaii externally than internally, more varieties are known to be adapted to external than to internal transport.

[单项选择] Since the early 1930s, Swiss banks had prided themselves on their system of banking secrecy and numbered accounts.

The result of this policy of secrecy was that a kind of mystique had grown up around Swiss banking. There was a widely-held belief that Switzerland was irresistible to wealthy foreigners, mainly because of its numbered accounts and bankers’’ reluctance to ask awkward questions of depositors. Contributing to the mystique was the view, carefully propagated by the banks themselves, that if this secrecy was ever given up, foreigners would fall over themselves in the rush to withdraw money, and the Swiss banking system would virtually collapse overnight.
To many, therefore, it came like a bolt out of the blue, when, in 1977, the
