Rolled Safari Poster Steadies a Wandering Mirror Beam- 適合中高級的英語短篇故事

Bea pressed a small mirror with its smooth plastic back onto a sun-warmed hardback, and the chill startled her fingertips. Dust lines danced in the entering beam as she nudged the book until a square bounced toward the centre of the room. A tabby cat on the sill tracked the light, and Yolanda flipped a magazine near the curtains. The book beneath the mirror had been printed by a wildlife photographer; glossy pages felt almost hot, and the heat softened the spine just enough to sag. That tiny bend unseated the mirror, its grip on the cover loosened, and the spot jumped onto a chair leg instead of the next reflector. The chain needed a knack for steady positioning. Bea grabbed a rolled safari poster from the supply box, wedged it beside the book, tilted the mirror again, and saw the beam smear a hand-span low on the white card.

She knelt in the adjustment zone, carpet weave pressing into her knees, when a cloud crossed the sun and the square dimmed. Brightness snapped back, yet the shifting sun had changed the entry angle; the spot now crawled toward the skirting board. Warm air rose along the beam, embracing a loose paper and making it twitch, while a corridor draft added another wobble. If the spot wandered again, the cat would spring after it. Bea tore a strip of tape, pinned the hot hardback to the table, then braced a fresh mirror against a cooler wooden block for firmer grip. The angle returned, though fresh heat soon began to bow the block. Late in the afternoon she slid two metal rulers into the curtain gap, blocking extra light and arresting the cascade. On the target wall, a round bright patch drifted across the card’s lower edge.

Bea 把一面背面光滑的塑膠小鏡子壓在被陽光曬熱的精裝書上，冰涼的觸感讓她的指尖一顫。透進室內的光束裡，灰塵線條舞動，她輕推書本，直到一道方形亮斑彈向房間中央。窗台上的虎斑貓追蹤著光點，簾邊的 Yolanda 翻著雜誌頁。鏡子下方那本攝影師出版的野生動物攝影集因受熱而書脊微軟，亮斑立即偏移，鏡面對封面的抓附力鬆開，光點跳到椅腳而非下一面反射鏡。這串反射需要穩定角度的技巧。Bea 抓起供應箱裡捲成筒的狩獵探險海報，塞在書旁，再次調整鏡子，亮斑在白卡下方抹出半掌寬的痕跡。

她跪在調整區，地毯紋路壓進膝蓋，這時一朵雲遮住太陽，亮斑瞬間暗淡。陽光又立刻回來，但入射角已經改變，光點沿著踢腳板慢慢爬行。沿光路上升的暖空氣包住桌上一張鬆散的紙，使紙張顫動，走廊的氣流又添一次晃動。若亮斑再度亂跑，貓大概會撲向它。Bea 撕下一截膠帶，把發熱的精裝書固定在桌面，接著用較涼的木塊支撐新鏡子，增加鏡面的抓力。角度恢復，但新熱量很快又讓木塊微微彎曲。下午後段，她把兩把金屬尺塞進窗簾縫，擋住多餘光線，終止了這場反射連鎖。目標牆上，一個圓形亮斑仍在白卡下緣慢慢滑動。
