Audiobook Dictation: “The test stand's breaking loose! Tom…”

The test stand's breaking loose!" Tom warned.

试验台要松脱了！”汤姆警告道。

Another engineer rushed toward the door to see what was happening outside.

另一名工程师冲向门口，想看看外面发生了什么。

Before he reached it, another shock knocked all of them off their feet.

他还没跑到门口，又一阵震动把所有人都掀翻在地。

Electronic equipment cascaded from the wall shelves, and a heavy-duty chain hoist came loose from its overhead track, plunging to the floor with a terrifying crash.

电子设备从墙上的架子上倾泻而下，一台重型链式起重机从头顶的轨道上脱落，轰然砸到地上，声音骇人。

"An earthquake!" Tom gasped.

“地震！”汤姆倒抽一口气。

"The roof! It's caving in!" he heard someone scream.

“屋顶！屋顶要塌了！”他听见有人尖叫。

Bud threw up his arms to protect himself, but too late!

巴德举起双臂护住自己，可是太迟了！

A falling beam caught him on the back of the head and the young flier blacked out.

一根落下的横梁砸中了他的后脑勺，年轻的飞行员顿时昏了过去。

For minutes, no one stirred among the wreckage.

好几分钟里，废墟中没有一个人动弹。

Then Tom, who had been stunned by some falling debris, raised himself to a sitting position.

接着，被掉落的碎片砸得发懵的汤姆撑起身子坐了起来。
