　　　Australia is a developed country and the future of its solar industry is looking bright after a record 3.5m panels (嵌板) were installed on rooftops last year, giving the equal output of a medium-sized coal-fired power station. The record 1,057 MW of capacity (生产能力) in small-scale systems installed across the country broke the previous record set in 2012, figures from the Clean Energy Regulator showed on Tuesday.

　　　Australia's solar power prosperity could almost double capacity in a year. The data also revealed that the average system size has also doubled since then from three to six kilowatts as average prices continued to fall. A fully installed 5KW system costs an average of $5,930 in Australia, according to the energy broker Solarchoice. net. au. Its records show that the price has roughly halved in many capital cities since 2012.

　　　The regulator's executive general manager, Mark Williamson, said there was increasing interest in renewals as a way to take control of electricity bills. But more importantly, he said it was also good news for reducing carbon emissions.

　　　"We are seeing a wide cross-section of Australians-households, community centers, schools, and small businesses-receiving rewards under the small-scale renewable energy scheme," Williamson said. "Our data shows consumers are embracing renewable energy to take control of their electricity bills."

　　　In 2017, there was a 41% increase in installing renewable energy capacity across all states and territories compared to 2016. Queensland led the way with installed capacity at 295MW, with the Australian Capital Territory taking top place for the biggest annual increase by 57%. "The data collected by the Clean Energy Regulator in 2017 reflects the industry is going from strength to strength. It looks like 2018 will be another big year for the solar industry."

　　　The total of installed capacity for last year is expected to rise to 1,070MW when all the data is collected. A large coal-fired power station such as Loyd Yang A in Victoria's Latrobe Valley has a capacity of 2,200MW.

　　　8．What do we know about the Australia's solar industry from the first paragraph?

　　　A．It's still risky.

　　　B．It's promising.

　　　C．It's unpredictable.

　　　D．It's within expectation.

　　　9．What's the reason for the Australia's solar industry's development?

　　　A．The entire decrease of the carbon emissions.

　　　B．The autonomous control of the electricity bills.

　　　C．The doubt about the capacity of coal-fired power station.

　　　D．The continuous fall of the average price of installing a solar energy system.

　　　10．What does the underlined phrase" from strength to strength" in Paragraph 5 suggest?

A．Australia's solar industry is being accepted.
