The Cat Jolt at the Marble Run- 適合中高級的英語短篇故事

The starting ramp stood firm, but the middle platform sagged slightly toward the carpet below. Hazel knelt, knees sinking into the warm pile, while a wary tabby crouched three steps away watching. Near the supply pile, an adult sorted wooden blocks by height, leaving Hazel to handle the finer adjustments. Her goal was simple: raise the platform enough so the marble could clear the sharp turn and keep rolling. She had rinsed dust from the marble under the kitchen faucet, and cool droplets still dotted its glass surface. First, she slid a thin paperback—eight millimetres thick—under the slipping tube and lowered the marble. It rolled farther yet drifted to a stop just before the turn, lacking an ounce of momentum.

Next, Hazel arched her back, reached behind, and swapped the paperback for a chunky wooden block twelve millimetres tall. The combined height now measured twenty millimetres, and the marble almost escaped the dip before sliding backwards again. If the tube sat any lower, the marble would freeze there every single time again. While the cat's tail twitched, an insight appeared: the surface itself needed a gentler angle, not just more lift. Hazel shifted her weight forward, pressed one palm against the tube, and wedged a folded postcard adding five extra millimetres. As she released the pressure, the support stack held firm, and the tube leaned downward by a hair. This time the marble shot through the sag, clattered around the sharp turn, and zipped into the landing bowl.

Before Hazel could breathe out, the tabby sprang across the carpet, paws thudding near the new stack. Vibration rippled underneath; the postcard slipped halfway, and the tube sagged again though only by a fraction. Hazel steadied the ramp with both forearms, shoulders tightening, while the cat circled the landing bowl sniffing the spinning glass. A fresh strip of red tape now angled across the loosened joint where the postcard showed a white edge.

起跑斜坡依舊穩固，但中段平台卻微微向下陷向地毯。Hazel 跪坐下來，膝蓋陷入溫暖的絨面，一隻警覺的虎斑貓在三步外蹲著觀察。補給堆旁，一位大人正在按高度分類木塊，留下細部調整給 Hazel。她的目標很簡單：把平台抬高，讓彈珠能順利通過銳角轉彎並持續前進。她先前在廚房水龍頭下沖掉彈珠上的灰塵，涼涼的水珠仍附著在玻璃面。她先把一本八毫米厚的輕薄平裝書塞到下滑的紙管下，再放下彈珠。彈珠滾得更遠，但在轉彎前停住，動能連一盎司都不剩。

接著 Hazel 向後伸手，拱起身子，用一塊十二毫米高的厚木塊取代那本書。總高度現在二十毫米，彈珠幾乎脫離下陷區，卻又倒退回來。若紙管再低一點，彈珠每次都會卡死在那兒。就在虎斑尾巴抽動時，她得到一個靈光：不只要抬高，更要調整角度。Hazel 把身體前移，一手壓住紙管，塞進一張摺疊明信片，又增加五毫米。當她放開壓力，支撐堆穩穩撐住，紙管微微下傾。這回彈珠穿過下陷處，撞響銳角轉彎，最後衝進終點碗。

Hazel 還來不及吐氣，虎斑貓便躍過地毯，爪子在新堆旁重重落下。震動沿地面擴散；明信片滑出一半，紙管再次下陷，但只低了一點點。Hazel 用前臂穩住斜坡，肩膀緊繃，而貓繞著終點碗聞著仍在旋轉的玻璃彈珠。紅色膠帶的新條紋此刻斜掛在鬆動的接縫上，明信片露出一角白邊。
