a. What evidence shows that Earth is getting warmer (A warming ocean and atmosphere, melting ice, rising sea levels.)
b. What happened to the polar bear in the photo (It died of starvation.)
c. Why did the polar bear starve (Low sea-ice levels caused by climate change meant it could not hunt seals as before.)
(2)阅读第3段,完成温室效应原理填空:
自然温室效应:
太阳辐射进入大气层,使地球表面变暖。
热量以长波辐射形式释放回太空。
大气中的温室气体(如甲烷、二氧化碳)拦截部分热量,保持地球气候温暖宜居。
若无此过程,地球无法维持生命。
人为温室效应:
人类燃烧化石燃料产生大量额外温室气体。
更多热量被拦截在大气层中,导致地球表面温度快速上升。
(3)阅读第4段,回答以下问题:
a. What are the consequences of rising temperatures (Extreme weather and natural disasters worldwide, causing deaths and economic losses.)
b. What does the author say will happen if greenhouse gas emissions continue (Further warming and long-lasting changes to the global climate.)
(4)阅读第5段,回答以下问题:
a. Who should take action to deal with climate change (Governments and individuals.
b. What can governments do (Make policies and take measures to reduce greenhouse gas emissions.)
c. What can individuals do (Reduce our carbon footprint by restricting the amount of carbon dioxide our lifestyles produce.)

后果(Consequences):极端天气、自然灾害、人员伤亡、经济损失
措施(Solutions):政府政策 + 个人行动(减少碳足迹)
2.长难句分析(可选,根据学生水平调整):
“An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died.”
结构分析:who引导定语从句修饰expert;that引导宾语从句;to have starved and died为不定式完成式作表语。
翻译:一位长期研究北极熊的专家说,从尸体的姿势看,这只北极熊像是饿死的。
3.策略指导:思维导图是将复杂信息可视化的有效工具,可以帮助我们更清晰地理解文本的因果逻辑结构。
(四)读后讨论·深化理解(10分钟)

The Causes and Effects of Climate Change
Climate change is one of the most serious problems facing our planet. The main cause is the man-made greenhouse effect caused by burning fossil fuels, which releases extra greenhouse gases into the atmosphere. These gases trap more heat, leading to a rise in global temperature. As a result, we are seeing more extreme weather events, such as floods and heatwaves, which cause deaths and economic losses. If we do not take action, the consequences will become even more severe.

任务一:简答(10分)
The author says climate change requires the world‘s attention because it is a global problem that affects everyone on the planet. No single country can solve it alone—it requires international cooperation. As individuals, this means we should take responsibility for our own actions, reduce our carbon footprint, and encourage others to do the same.
任务二:参考范文(20分)
How to Protect Our Planet
Protecting our planet is everyone’s responsibility. First, we can reduce our carbon footprint by walking, cycling, or using public transport instead of driving cars. This helps reduce greenhouse gas emissions. Second, we should save energy by turning off lights and electrical devices when we are not using them. Third, we can plant trees and recycle waste to reduce pollution. Finally, we can educate others about climate change and its consequences. Every small action counts. Together, we can make a difference and create a more sustainable future for our planet.
