B（课文：damaged the Fukushima Daiichi nuclear power plant） 4. B（课文：More than 150,000 people had to leave） 5. B（课文：disasters often cause a chain reaction, leading to more problems） 配套练习 B 1. serious 2. highlighted, chain reaction 3. atmosphere 4. deal 5. responsibility, reduce 拓展思考（示例） Part 1 I have heard about the 2011 earthquake in Japan. It caused a huge tsunami. The secondary disaster was the nuclear power plant explosion. People had to leave their homes because of radiation. This shows that one disaster can lead to many others. Part 2 Dear neighbours, to reduce secondary disasters, we should prepare emergency kits. After an earthquake, we must turn off gas to avoid fires. It is important to listen to the news for tsunami warnings. Let’s work together to make our community safer. Part 3 Secondary disasters can be as dangerous as, or even more than, the main disaster because they often come unexpectedly. For example, after an earthquake, a fire or flood may cause more deaths than the quake itself. Therefore, we should prepare for both. Being prepared for both primary and secondary disasters saves lives. 1 学科网（北京）股份有限公司 $
