[填空题]More than two million people in Europe now have fibre broadband direct to their home, suggests a survey.
The latest figures on superfast broadband delivered by fibre to the home (FTTH) shows 18% growth over the last survey compiled in late 2008.
The continued growth suggests that the global economic downturn has not hit plans to build a fibre infrastructure (基础设).
Sweden tops the list of nations rolling out the technology, with 10.9% of its broadband customers using fibre.
Karel Helsen, president of Europe’s Fibre-To-The-Home Council, said the growth matched predictions that were revised when the credit crunch (信用紧缩) started to make itself felt.
"The numbers in 2009 are in line with the latest forecasts," said Mr. Helsen.
By 2012, the FTTH Council expects that 13 million people across 35 European nations will have their broadband delivered by fibre. Such services would start at speeds of 100 megabits per second (mbps), said Mr. Helsen.

[单项选择]When scientists are trying to understand a particular set of phenomena, they often make use of a "model." A model, in the scientists’ sense, is a kind of analogy or mental image of the phenomena in terms of something we are familiar with. One example is the wave model of light. We cannot see light as if it were made up of waves because experiments on light indicate that it behaves in many respects as water waves do.
The purpose of a model is to give us a mental or visual picture -- something to hold onto -- when we cannot see what is actually happening. Models often give us a deeper understanding: the analogy to a known system (for instance, water waves in the above example) can suggest new experiments to perform and can provide ideas about what other related phenomena might occur.
Another example of a scientific model would be ______.
A. a map
B. a paper airplane
C. an atom
D. a light bulb
