California burns every year, but 2020 is the worst year yet. In a study, more than 77,600 fires    1    (burn) over 2.5 million acres of land so far this year. Unfortunately, the season still has months to run. Over the past decade, the state has spent    2    average of $ 3.7 billion a year    3    (fight)fires.

Clever designs can help make buildings fight against fires that spread 10 neighboring buildings.    7    (material) such as concrete, adobe or stucco are a better bet than walls in a flammable wood, some of    8    promise to hold back the flames for two hours or more. Besides, opening agricultural lands can be a useful measure, too. Australia, which also suffers    9    wildfires, has experimented with bunkers (掩体) specially    10    (design) to hold back fires for an hour or more.

A hurricane happens together with heavy rainfall, thus     1    (result) in destroying flood.
