Milo Beside the Stalled Crane- 適合中高級的英語短篇故事

Milo balanced on a paint-splashed stool beneath the workshop roof. His science-fair project, a pocket-sized crane, waited on the bench. The arm, built from an ice-cream stick and a toy motor, aimed to hoist a miniature steel girder onto a cardboard bridge. He had spent weeks soldering wires until the device finally whirred. A tiny coil lay behind the switch; when current passed through, magnetic excitation inside the coil ought to raise the arm smoothly. The teacher had been impressed when the plan was first described, and Milo had hoped the demonstration would unfold without drama.

He pressed the button. A brief click, then silence. The arm refused to move. Milo opened the housing; a grain of sawdust blocked the gear mechanism. He brushed it away, tightened the screw, and tried again. The motor spun, yet the hook drifted sideways, dropping the steel girder onto the mat. If the hook had carried more weight, the fragile bridge would have collapsed. Sweat dotted his nose as he replaced the nylon thread with a stronger strand. Even then, the arm wobbled because the axle had been mounted crookedly. The second failure left his shoulders tense, but he kept adjusting alignments until every cog meshed.

On the third attempt, the motor purred, the arm lifted, and the hook steadied over the bridge. Just then, a loud pop sounded; a hidden balloon under the platform burst, sending confetti into the air. Milo blinked while bright paper drifted around the bench—his friend Vida had secretly added the balloon as a surprise catalyst, hoping to turn a routine lift into a spectacle. For a moment the crowd gasped, then laughter rolled across the room as the crane completed its journey. The hook set the steel girder into place, confetti settled on the bridge, and the tiny wheel rested against the polished track.

米洛站在佈滿油漆斑點的凳子上，屋頂下的工作室光線斑駁。他的科展作品──一座袖珍起重機──正安靜地擺在工作台上。吊臂由冰棒棍與玩具馬達組成，目標是把微型鋼梁放到紙板橋上。他花了數週焊接電線，好不容易讓這項裝置發出嗡嗡聲。開關後方躺著一枚小線圈；當電流通過時，線圈內的激磁作用應該能平順地抬起吊臂。計畫首次被介紹時老師曾經讚賞，米洛也曾經希望示範能毫無波折地進行。

他按下按鈕，先是輕脆一響，隨即陷入寂靜。吊臂停在原地不動。米洛打開外殼；一粒鋸屑堵住了齒輪機構。他拂去木屑、擰緊螺絲，再試一次。馬達轉動，但吊鉤斜向一旁，鋼梁跌落在墊子上。若吊鉤當時承載更重的東西，那座脆弱的橋恐怕早已塌陷。汗珠浮上他的鼻尖，他把尼龍線換成更結實的繩子。即便如此，因為軸心歪斜，吊臂仍然搖晃。第二次失敗讓他的肩膀繃緊，但他繼續調整，直到每個齒輪都咬合順暢。

第三次嘗試，馬達發出均勻的嗡鳴，吊臂升起，吊鉤穩穩懸在橋上。就在此刻，一聲砰響傳來；平台下方的氣球爆裂，五彩紙片漫天飛舞。米洛眨眼時，亮麗的紙片在工作台周圍飄散──他的朋友維達暗中放入這顆氣球，想用它當作驚喜的催化劑，把普通的吊運變成表演。短短一瞬，全場先是倒抽一口氣，接著笑聲翻湧。起重機完成最後行程，吊鉤把鋼梁放到位，紙片落在橋面，微型車輪停在光滑的軌道邊。
