Question 26 - 35.
Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the questions.
Global warming is one of the most pressing issues of our time, caused by a rapid increase in greenhouse gases in the Earth's atmosphere. (I) Human activities, particularly the burning of fossil fuels like coal, oil, and gas, release large amounts of carbon dioxide (CO₂) into the air. (II) These gases trap heat from the sun, creating a "greenhouse effect" that warms the planet. (III) While the Earth’s climate has changed throughout history, the current rate of warming is unprecedented and poses serious challenges. (IV)
The impacts of global warming are far-reaching. Rising temperatures are causing polar ice caps and glaciers to melt, leading to higher sea levels. This puts coastal cities and low-lying areas at risk of flooding. Additionally, warmer oceans can intensify hurricanes and other extreme weather events. Changes in temperature and rainfall patterns disrupt ecosystems, threatening wildlife and leading to biodiversity loss. Global warming also affects agriculture, with heatwaves and droughts making it harder to grow crops in some regions.
Addressing global warming requires urgent action. Reducing greenhouse gas emissions is key to decelerating climate change. Governments, industries, and individuals all have roles to play. Transitioning to renewable energy sources like solar and wind power can significantly cut emissions. Protecting forests, which absorb CO₂, and investing in energy-efficient technologies are also critical. By working together and adopting sustainable practices, we can mitigate the effects of global warming and secure a healthier future for our planet.
Which of the following best summarises paragraph 2?
The effects of global warming include flooding, stronger storms, and changes in ecosystems.
Global warming threatens wildlife and agriculture while causing extreme weather.
The rising temperatures caused by global warming are a threat to human survival.
Climate change leads to environmental and agricultural challenges for all regions.
Giải thích chi tiết
Ứng dụng 😎 Linearthinking để giải quyết câu hỏi: Step 1: Read the text ✏️ Simplify & Read connection Đoạn 2
Nhóm câu 1 + 2 + 3 + 4 + 5: Cùng chức năng = liệt kê các tác động (impacts) của global warming (dấu hiệu: mở đoạn “The impacts…”, sau đó là chuỗi hệ quả nối tiếp)
Từ khóa:
tăng nhiệt độ Rising temperatures → tan băng, tăng mực nước biển ice caps/glaciers melt → higher sea levels → ngập lụt vùng ven biển coastal flooding risk
biển ấm lên warmer oceans → bão mạnh hơn, thời tiết cực đoan intensify hurricanes / extreme weather
thay đổi nhiệt độ & mưa changes in temperature and rainfall → rối loạn hệ sinh thái disrupt ecosystems → đe dọa động vật/giảm đa dạng sinh học wildlife threatened / biodiversity loss
ảnh hưởng nông nghiệp affects agriculture → nắng nóng, hạn hán khó trồng trọt heatwaves & droughts → harder to grow crops
🔗 Summarize idea flow:
Topic sentence: Đoạn 2 = tác động rộng khắp impacts are far-reaching
List/Sequence: tăng nhiệt độ → tan băng/biển dâng → ngập lụt; biển ấm → bão mạnh; thời tiết thay đổi → hại hệ sinh thái; → hại nông nghiệp
📌 Main idea: Global warming impacts → flooding (sea level rise) + stronger storms (extreme weather) + ecosystem disruption (biodiversity loss) + agriculture problems
Step 2: Compare options A. The effects of global warming include flooding, stronger storms, and changes in ecosystems. ✅ Đúng — khớp trực tiếp 3 ý lớn trong đoạn: flooding (sea levels), stronger storms (hurricanes/extreme weather), ecosystem changes (disrupt ecosystems).
B. Global warming threatens wildlife and agriculture while causing extreme weather. ❌ Sai — có 3 ý đúng (wildlife/agriculture/extreme weather) nhưng thiếu ý flooding/sea level rise, trong khi đây là ý nổi bật đầu đoạn 2.
C. The rising temperatures caused by global warming are a threat to human survival. ❌ Sai — đoạn 2 không nói “human survival”; đây là suy rộng ngoài văn bản.
D. Climate change leads to environmental and agricultural challenges for all regions. ❌ Sai — quá chung và thêm tuyệt đối hóa “for all regions”; đoạn 2 nêu cụ thể coastal cities/low-lying areas và liệt kê tác động cụ thể (flooding, storms, ecosystems).
