Ⅱ. 根据课本的听力内容,按要求完成下列任务。
任务一:阅读短文,完成报道记录。
I'm walking along a busy beach in Thailand. Many families and friends are enjoying themselves. It's been many years since a tsunami hit here. The tsunami was terrible, but there were lots of touching moments. Some people, like Tilly Smith, saved lives bravely with their knowledge. This clever 12-year-old girl saw the water going farther down the beach. It wasn't calm. She knew that a tsunami was coming. She learned about tsunamis at school two months earlier. Tilly warned people on the beach. So they all ran to a hotel. Minutes later, the tsunami hit. That school lesson saved about 1000 lives. Knowledge can make a big difference between life and death.
