B On December 26, 2004, a massive earthquake struck under the Indian Ocean. It triggered a tsunami that devastated coastal communities in several countries. Thousands of people were caught off guard. However, on one beach in Thailand, a 10-year-old British girl named Tilly Smith saved many lives. Tilly had learned about tsunamis in her geography class just two weeks earlier. While she was walking on the beach with her family, she noticed that the water was bubbling and the sea was pulling back. She remembered what her teacher had taught her — these were signs of a coming tsunami. She told her parents, who warned the hotel staff and other tourists. They quickly evacuated the beach. Thanks to Tilly's quick thinking, about 100 people were saved that day. Tilly became famous for her bravery and knowledge. Her story shows that learning about disasters can save lives. ( )6.

How many people did Tilly's warning save? A. About 10. B. About 100. C. About 1,000. D. About 10,000. C Disaster warning systems are essential for saving lives in the event of natural disasters. These systems use different technologies to detect and warn people about upcoming dangers. For example, tsunami warning systems use seismic sensors to detect earthquakes under the sea. When a large earthquake is detected, the system calculates whether a tsunami is likely and sends out warnings. Modern warning systems include text messages, TV broadcasts, online notices, and mobile apps. China has one of the most advanced warning systems in the world. The government can send warnings to millions of people within seconds. Warning times for storms in China have been increased to 42 minutes, with more than 90% being correct. Despite these advances, some disasters, like earthquakes, are still difficult to predict accurately. The warning time for earthquakes is very short, sometimes only a few seconds. Therefore, it is important for people to learn how to react quickly to warnings. Education about disaster preparedness is just as important as the warning systems themselves. Together, warnings and education help keep communities safe. ( )11. What is the main idea of the passage? A. Warning systems are not effective. B. Warning systems and education work together to save lives. C. Earthquakes can be predicted easily. D. Only China has warning systems. ( )12. What technology is used in tsunami warning systems? A. Drones. B. Seismic sensors. C. Satellites. D. Radios. ( )13. How long is the warning time for storms in China? A. 42 minutes. B. 42 seconds. C. 24 minutes. D. 24 seconds. ( )14. Why is the warning time for earthquakes very short? A. Because earthquakes are easy to predict. B. Because technology is not advanced enough. C. Because earthquakes happen suddenly with little warning. D. Because people ignore warnings. ( )15. What is important besides warning systems according to the passage? A. Building more shelters. B. Education about disaster preparedness. C. Making more apps. D. Sending more text messages. 八、完形填空（阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳答案） Disaster warnings are very important.
