阅读理解。 When the earthquake hit Japan on March 11, 2011, workers in a supermarket in Japan didn't run away when they felt the shaking. Instead, they held on to the shelves and tried to stop the goods from falling down. Reporters from NHK, the country's largest TV station, stayed calm in front of cameras during the earth quake, even though some were facing real danger. The earthquake was the most powerful one to hit Japan in the country's history. But Japan's reaction to the earthquake has shown that it is the most earthquake-prepared (有准备的) country in the world. The calm that Japanese showed during and after the quake has impressed the world. This is because Japan has an earthquake culture. Japanese people are taught how to prepare for and react to an earthquake from a young age. One way kids learn about earthquake safety is from the cartoon character Maruko, a 9-year-old student. In Chibi Maruko-Chan (《樱桃小丸子》), Maruko has to wear a protective (防护的) hat in an earthquake practice. Schools in Japan organize earthquake practices every month. They make students become familiar (熟悉的) with being in an earthquake. Japan also has a good earthquake warning (警报) system. Warnings were broadcast on TV, the radio and cell phones eight seconds after experts first knew about the quake on March 11. The warning system is unable to predict an earthquake, but it can usually alert (提醒) people about 15 seconds before they feel the effects. Even 15 or 20 seconds can be enough to save people's lives. 1. When the big earthquake happened in Japan on March 11, ______.
