Curve in the Final Beam- 適合中高級的英語短篇故事

A pale rectangle on the carpet marked the spot where Finn expected the first mirror, yet nothing stood there. He knelt, the weave pressing into his knees, and traced the narrow beam that still slipped through the curtain gap like polished steel. Outside, clear skies kept the sunlight strong, while Heath turned pages of a paperback beside the window and said nothing. Finn opened the supply box, chose a mirror with elegant design, and felt its plastic back stay cool against his warm palm. A striped cat unfolded from the shade, blinking at the radiant glow that drifted across its whiskers before sliding away. Using a trustworthy protractor, Finn propped the mirror against a paperback and eased it into place.

The light spot leaped to the relay mirror, then climbed toward the white card, yet it stopped three fingers short of the target. Finn nudged the paperback slightly, the beam kissed the card’s edge, yet the book tipped sideways. The support slid across the table with a dry shuffle, loosening the tape that held the card flat. Finn clenched his teeth as the cat’s tail flicked and Heath murmured, “That squeak sounded resentful” when the tape peeled. Meanwhile, the sun inched across the clear glass, gradually pushing the bright spot farther off course. Finn waited for the next cloud to dim the beam, then snatched the chance to reorder his setups in a calmer rhythm. He slid the paperback under the card as ballast, placed a slim notebook beneath the mirror next, and watched both items steady. A narrowed beam reappeared, trembling but usable, and the cat sat beside it like a statue, whiskers lit silver.

The spot finally reached the white card, wobbling within a small oval rather than a perfect circle. Finn stepped back once the relay mirror still held its angle, even though the card’s curling corner stayed slightly shadowed. Heath turned another page, the cat blinked slowly, and dust motes sailed through the tilted path of light toward the bookshelf. Outside, a breeze tugged the curtain, and the beam shifted half a finger, yet it kept travelling across the improvised maze. Beyond the carpet edge, those bright motes kept drifting in the slender column long after Finn walked toward the doorway.

地毯上出現一道淺色長方形，正是芬恩原本放第一面鏡子的地方，此刻卻空無一物。他跪下，地毯紋理在膝蓋上留下壓痕，沿著仍從窗簾縫隙溜進來、像打磨過鋼帶般的細光束尋找方向。窗外萬里無雲，陽光穩定灑落，而希斯靜坐窗旁翻閱平裝書，未發一語。芬恩打開補給盒，挑出一面設計俐落的小鏡子，鏡背的塑膠在他溫熱的手心裡依舊冰涼。一隻虎斑貓自陰影中伸展，對著掠過牠鬍鬚的明亮光暈眨眼。芬恩拿可靠的量角器確認角度後，把鏡子靠在平裝書上，小心就位。

光點跳向中繼鏡，再往白色卡紙爬去，卻還差三指才能命中。芬恩輕推平裝書，光束碰到卡紙邊緣，書卻側倒。支撐物在桌面上發出乾磨聲滑移，鬆動了壓平卡紙的膠帶。貓尾一甩，膠帶發出聲響，希斯低聲說：「那聲嘎吱聽起來頗帶怨氣。」同時，太陽沿著玻璃緩緩移動，亮點的落點又被推離。趁下一片雲遮光時，芬恩抓緊機會重新安排步驟、節奏更平穩。他先把平裝書塞到卡紙下做配重，再把薄筆記本墊到鏡子下，目送兩處都站穩。光束縮細重現，雖顫抖卻可用，貓像雕像般伏在旁邊，銀亮鬍鬚閃動。

光點終於落在白卡上，雖只成不完美的小橢圓。芬恩退後一步，確認中繼鏡還維持角度，即便卡紙一角仍微微翹起。希斯又翻一頁，貓慢眨雙眼，塵粒順著傾斜光路飄向書架。窗外微風拉動窗簾，光束偏移半指寬，仍沿著即興迷宮前行。地毯邊緣之外，那些亮塵在細長光柱中繼續飄浮，遠在芬恩走向門口之後。
