[单项选择]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.
The author of the passage is
A. discussing different approaches biologists have taken to testing theories about the distribution of plants in Hawaii
B. discussing different theories about the transport of plant seeds to Hawaii
C. discussing the extent to which air currents are responsible for the dispersal of plant seeds to Hawaii
D. resolving a dispute about the adaptability of’ plant seeds to bird transport

[单项选择]It is the staff of dreams and nightmares. Where Tony Blair’s attempts to make Britain love the euro have fallen on deaf ears, its incarnation as notes and coins will succeed. These will be used not just in the euro area but in Britain. As the British become accustomed to the euro as a cash currency, they will warm to it--paving the way for a yes note in a referendum.
The idea of euro creep appeals to both sides of the euro argument. According to the pros, as Britons become familiar with the euro, membership will start to look inevitable, so those in favor are bound to win. According to the antis, as Britons become familiar with the euro, membership will start to look inevitable, so those opposed must mobilize for the fight.
Dream or nightmare, euro creep envisages the single currency worming its way first into the British economy and then into the affections of voters. British tourists will come back from their European holidays laden with euros, which they will spend not jus
A. to be over-enthusiastic about the success of the euro.
