2025年补充习题江苏八年级英语上册译林版第51页解析答案

B Read the profile of heatwaves and decide whether the sentences are true (T) or false (F). If the sentence is false, write the correct answer.
Heatwaves: a closer look
A heatwave is a period of hotter-than-usual weather in an area. Heatwaves can last a few days or even weeks. They can be very dangerous. Every year, hundreds of thousands of people die in heatwaves.
Causes
Heatwaves are happening more often and becoming more harmful to people and the environment.
• Climate change: As temperatures around the world rise, extreme heat is getting more common.
• Urban heat island effect: Cities are usually a little hotter than nearby areas. This is because roads and buildings trap a lot of heat.
A recent example
Heatwaves can happen all over the world. In 2021, a very bad heatwave hit the Pacific Northwest area of North America. The heatwave broke temperature records in many cities in Canada and the USA. During the event, hundreds of people died. The heatwave also killed about one billion ocean animals and damaged crops.
Safety tips
We can’t prevent heatwaves, but we can protect ourselves when they happen.
• Stay inside: On very hot days, it’s better to stay inside as much as possible.
• Keep your home cool: Close windows and curtains during the day to keep heat out. Use fans or air conditioners to stay cool.
• Drink water: Drink a lot of water to stay cool and healthy.
Heatwaves are a serious problem. We need to be careful and protect ourselves.
