利用雲層阻止聖嬰現象
Introduction
Scientists have a new plan. They want to use clouds to stop El Niño and save money.
科學家有一個新計畫。他們希望利用雲層來阻止聖嬰現象並節省開支。
Main Body
El Niño makes the ocean warm. This causes hot weather and money problems. Scientists want to spray salt water into clouds. These clouds reflect sunlight back to space. This keeps the ocean cool.
聖嬰現象會使海洋變暖。這會導致酷熱天氣與經濟問題。科學家希望將鹽水噴入雲層中。這些雲會將陽光反射回太空，從而使海洋保持涼爽。
Scientists looked at big fires in Australia. Smoke from the fires made the air cool. They used computers to test this idea. The computers show that this plan can stop the ocean from getting too hot.
科學家研究了澳洲的大規模火災。火災產生的煙霧使空氣冷卻。他們使用電腦測試這個想法。電腦顯示此計畫可以阻止海洋溫度過高。
But this plan is hard. They need 2,400 ships. We do not have the right tools yet. Also, some people are worried. This plan might help one place but hurt another place, like Africa.
但這個計畫很困難。他們需要 2,400 艘船。我們目前還沒有適當的工具。此外，有些人感到擔心。這個計畫可能會幫助一個地區，但卻損害另一個地區，例如非洲。
Conclusion
The plan works on computers. But it is dangerous and difficult in real life.
該計畫在電腦模擬中可行。但在現實生活中，它既危險且困難。
Vocabulary Learning
🧊 The "Make/Keep" Logic
Look at how we describe changes in the text:
- Make creates a new state. (Example: "El Niño makes the ocean warm")
- Keep maintains a state. (Example: "This keeps the ocean cool")
Simple Rule: If something is changing, use Make. If something is staying the same, use Keep.
🛠️ Word Pairs for A2
Notice these opposites in the story. Learning them together is faster than learning them alone:
| Hot | Cool | |
|---|---|---|
| Help | Hurt | |
| Dangerous | Safe (implied) |
💡 The "Can" Power
The text uses can to talk about possibility:
- *"this plan can stop the ocean"
A2 Tip: Use can + action word to say something is possible.
- It can rain.
- I can help.
