New Satellite Study of a Big Tsunami
關於一次大海嘯的新衛星研究
Introduction
Scientists used a new satellite called SWOT to study a big tsunami in the Pacific Ocean. This tsunami started from a very strong earthquake in 2025.
科學家使用了一顆名為 SWOT 的新衛星來研究太平洋的一次大海嘯。這次海嘯是由 2025 年一次強震引起的。
Main Body
The SWOT satellite takes wide pictures of the ocean. Old tools only saw small parts of the water. This new satellite saw a very large area of the ocean waves.
SWOT 衛星能拍攝海洋的寬幅圖像。舊有的工具只能觀察水域的一小部分。而這顆新衛星則觀察到了極大範圍的海洋波浪。
Scientists thought all big waves moved the same way. But the satellite showed something different. Some parts of the wave moved faster than other parts. This created smaller waves behind the big wave.
科學家原以為所有大波浪的移動方式都相同。但衛星顯示出了不同的結果。波浪的某些部分移動速度比其他部分快，這在大波浪後方產生了較小的波浪。
Researchers also looked at the earthquake. They found the break in the ground was 400 kilometers long. This is longer than they first thought. They used the satellite and ocean buoys to find this answer.
研究人員還分析了這次地震。他們發現地表破裂長達 400 公里。這比他們最初預想的要長。他們利用衛星和海洋浮標找到了這個答案。
Conclusion
The SWOT satellite helps us understand tsunamis better. This can help people predict tsunamis in the future.
SWOT 衛星幫助我們更好地理解海嘯。這能幫助人們在未來預測海嘯。
Vocabulary Learning
The 'Comparing' Trick
To reach A2, you need to show how one thing is different from another. Look at how the text compares the New Satellite vs. Old Tools.
The Pattern:
Old thing Small/Limited
New thing Big/Better
Examples from the text:
- Old tools saw small parts
- New satellite saw a very large area
How to use this in your own English: Instead of just saying "The car is fast," compare it to something else to sound more advanced:
- My old phone was slow my new phone is very fast.
- The first book was short the second book is long.
