Low Tide Before Dawn - 適合進階的英文短篇故事，含中譯與發音

Marta reached the wooden footbridge while the sky still guarded its final stars. Below her, the estuary revealed wide bands of mud where the water had slid back toward the open sea. She knelt, lifted a handheld sensor, and aimed its beam toward a pale patch glimmering several steps ahead. The reading hinted at carbon dioxide ice—rare at sea level, possible only under an odd collision of winter chill and a wandering jet stream that had cooled the coast overnight. Her glove tapped the side pocket; spare batteries rattled, ready for a quick change.

A narrow plank path led from the bridge to the flats. Marta stepped off, and her boot sank deeper than expected. The mud behaved like a quagmire, sucking at the leather with a wet gasp. She leaned forward, braced a palm against the plank, and pulled hard; the boot refused, then released with a slurp that splattered her trouser leg. Cold liquid crept inside the seam. Wind rushed over the reeds, tilting them east, and she had to draw on every scrap of balance to stay upright. Another step planted her weight on a hidden root, but it shifted and rolled. Marta toppled, elbow first, into a shallow puddle, and her sensor skidded beyond her reach, its screen blinking yellow.

She crawled after the device, fingers stinging in the water. When her hand closed around the casing, she noticed that the puddle’s base gleamed white, not brown. Her fall had scraped away the top layer of sludge, uncovering a thin shelf of carbon dioxide ice lying under the mud itself. The surprise rewrote her plan: the original patch she had targeted was smaller, yet here stretched a broader, concealed sheet waiting for measurement. She set the sensor flat, wiped the screen with a soaked sleeve, and started a new scan while the tide murmured farther out. Above the estuary, wind arrows traced restless curves across the clouds, and a fresh crust of carbon dioxide ice rested beside her boots.

瑪塔抵達木橋時，天空仍守著最後幾顆星。她俯身舉起手持感測器，朝前方幾步外微微發光的淡色斑塊掃描。讀數暗示那可能是二氧化碳冰——在海平面上相當罕見，只有因冬季寒流與遊離急流聯手冷卻海岸才會出現。她用手套輕拍側袋，備用電池在裡頭碰撞作響。

從橋面延伸到灘地的狹窄木板小徑在泥灘上鋪展。瑪塔踏下第一步，靴子比預期陷得更深。泥漿如沼澤般吸住皮革，發出濕潤的啜聲。她前傾，手掌撐在木板上，用力一拉；靴子先是卡住，隨後伴著「啵」的一聲脫出，濺起的泥水弄髒褲管，冷液沿縫隙滲入。蘆葦在風中東倒西歪，她得調動全部身體重心才能勉強站穩。再走一步，腳下暗藏的樹根滑動，她整個人向前跌進淺水窪，感測器滑出手心，螢幕閃著黃色。

她爬向裝置，手指在水中發麻。握住外殼時，她注意到水窪底部呈現白色而非棕色。她的跌倒刮去了表層淤泥，露出泥下薄薄一層二氧化碳冰。這個意外改變了原本的計畫：她先前鎖定的斑塊反而較小，眼前這片隱藏的冰層等待測量。她把感測器平放，用濕袖擦拭螢幕，重新開始掃描，遠處潮聲低語。河口上空，風在雲中劃出不定軌跡，更薄的一層二氧化碳冰安靜地貼著她的靴子旁。
