In cooperation with other reservoirs (水库), the project can help Wuzhou, a city with     5     population of over 2.8 million in Guangxi, deal with once-in-a-hundred-year floods. Previously, the city was only able to hold floods that occur once every 50 years. The project also enables some cities in the Pearl River Delta     6     (resist) floods that happen once every two centuries.

The ministry said the Datengxia facility will also provide strong support for rural development, offering irrigation (灌溉) water to 80,000 hectares of farmland and     7     (address) drinking water shortage for almost 1.4 million people in Guangxi.

The project has already played     8     (significance) roles in the past three years when it was put into trial operation. For example, in June last year, it helped prevent     9     store about 700 million cubic meters of floodwater when the Xijiang River     10     (hit) by a flood. In the peak, it reduced water flow by 3,500 cubic meters per second.

“I was     5    (extreme) happy to help,” said Francis Stonier, 42, associate professor in the Education Department of Southwest University. He said he     6    (volunteer) many times in the US in the past years—for example, building houses for homeless people after big stom

“It was great to see such an outpouring of help in the extreme heat,” he said,     7    (note) that he was impressed     8     the number of locals who came to help.
