In railway and underground stations, people 　3 　posters and maps telling them 　4　 to go and what to do in the emergency. This was　 　5 　Flood –call. London wasn’t flooded yet. But it is 　6　 that it will be.

In 1236 and 1663, London was badly flooded. In 1928, many people　 　7 　in Westiminister, the heart of　 　8 　were drowned in floods. And in 1953, 100 people living on the eastern edge of the London suburbs were 　9　 　again in the floods. 　10 　, the Greater London Council (议会) is taking action to 　11 　this terrible accident happening again. 　12 　the flood wall will not　 be built until the 1980s. And in the meantime, Londoners 　13 　be prepared. When it 　14 　, 50 underground stations will be 　15 　water. Electricity, gas and phone services will be out of　 16 　. Roads will be impossible. It will be impossible to 　17　 any of the bridges between North and South London. Imagine ---- London will 　18 　like Venice.
