Every year, 12,000 to 14,000 e【小题1】 happen around the world, killing tens of thousands of lives. So when scientists talk about monitoring(监测)earthquakes, every second counts. Recently, a new AI system d【小题2】 by China is shortening the time it will take to detect(探测)earthquakes.

After an earthquake happens, most researchers can quickly release(发布)the time, p【小题3】, magnitude(震级)and depth of the earthquake. H【小题4】, they often don’t include the focal mechanism parameters(震源机制参数), which can be used to predict(预测)the possible distribution(分布)of strong aftershocks(余震).

“It t【小题5】 three to 10 minutes for other countries to release the focal mechanism parameters, but by this time, the earthquake has fully happened and the h【小题6】has been done,” Zhu said. “This new system can p【小题7】 the focal mechanism parameters in just one second and release the information before the aftershocks reach some areas.”

“If we are a【小题8】 to receive the warning information three seconds earlier after an earthquake happens, we’ll be able to r【小题9】 the wounded by 14 %. With 10 seconds earlier, the wounded can be reduced by 39%.” Zhu said.

This improvement is possible thanks to a deep learning method. The system is trained with millions of earthquake samples(样本). It’s now t【小题10】 in Yunnan and Sichuan provinces.

Have you ever watched or heard of the variety show called Sisters Who Brave Winds and Waves(乘风破浪的姐姐)? It was very popular 【小题1】 young people this year.

In our real life, there are also some ladies 【小题3】 brave winds and waves in different fields. Let’s take Yu Fengying as an 【小题4】. During this summer, there was a flood in Jiangxi province. Many villages were destroyed by the flood and many people lost their homes. In such 【小题5】 difficult time, a group of ladies joined the soldiers in fighting against the flood. Most of them were over 50 years old. 【小题6】 they couldn’t carry the heavy sandbags, they helped to fill the bags with sand. Yu Fengying was the captain of this group. She was very proud and said, “The members of our group all liked 【小题7】 in the square, we were square dancers before. But when the flood came, we made 【小题8】 our mind to do something we could to protect our hometown.” In their free time, they even cooked food for the soldiers. “These sisters are very kind, and they truly made us feel the warmth of family.” one of the soldiers said.

The s【小题4】 thing was that waves from the coast and rivers flooded the land and carried three crocodiles to near my house! One of my neighbours hit a crocodile with his car—it was 1.6 metres long.

Becky: Really? That’s hard to believe! So is everything b【小题5】 to normal again now?

Fiona: Not really. The floods have gone, but they destroyed a lot of homes and farms. It’s going to cost at least 110 million dollars to repair the damage.

Becky: Is the w【小题6】 usually this bad?
