比大脚车还要大。 萨拉·科特马滕、基思·科特马滕 著

Big Movers Have you ever seen a monster truck? Monster trucks have big wheels and can drive over almost anything. As big as monster trucks are, some vehicles are even bigger.

大块头运输工具 你见过大脚车吗？ 大脚车有着大大的轮子，几乎能碾过任何东西。 虽说大脚车已经很大了，但有些交通工具还要更大哦。

Vehicles that move things and people. The duck. The duck is a truck that can travel on both land and water. On land, the duck travels on six wheels. In water, the duck uses a propeller. The duck can carry people and supplies to places that are hard to reach. Rescue workers sometimes use this truck to pick up people caught in storms. You can even ride a duck for fun in some places.

这些交通工具负责运送货物和乘客。 鸭子车。 鸭子车是既能在陆地走、又能在水上开的卡车。 在陆地上，鸭子车靠六个轮子前进。 在水里，鸭子车靠螺旋桨推进。 鸭子车能把人和物资运到难以抵达的地方。 救援人员有时会用它救出被困在暴风雨里的人。 有些地方你还能乘坐鸭子车游玩呢。

Vehicle Bridge This amazing machine is both a vehicle and a bridge. The vehicle bridge is used in places where there are no roads or bridges. The vehicle moves the bridge into place. Then the bridge moves up and over the gap. Other vehicles can then drive across. When the bridge is no longer needed, it folds up onto the vehicle.

架桥车 这个神奇的机器既是交通工具，又是桥梁。 架桥车用在既没有公路也没有桥梁的地方。 先由车辆把桥身运到指定位置。 接着桥身展开架在缺口上方。 其他车辆就可以从上面开过去了。 等不再需要桥的时候，它就会折叠收回到车上。

cranes. Cranes lift and move heavy objects from one place to another. These machines help workers build buildings and load and unload cargo. Some of the world's largest cranes move containers from ships to land. Others are used to lift supplies to the tops of buildings.

起重机。 起重机可以把重物吊起，从一个地方运到另一个地方。 它们帮工人建造楼房，还能装卸货物。 世界上有些巨型起重机负责把集装箱从轮船运到岸上。 还有的起重机负责把建材吊到高楼顶端。

Dump Trucks The world's biggest dump trucks are found at mines. Miners use these trucks to haul loads of rocks and dirt. Some trucks can move up to 400 tons of soil. Because they carry such heavy loads, they use some of the biggest tires in the world. Their tires are over 13 feet, 4 meters tall, twice as tall as a person.

自卸卡车 世界上最大的自卸卡车在矿区工作。 矿工用这些卡车运送大量石块和泥土。 有些卡车一次能运多达400吨的泥土。 因为要运这么重的货物，它们用的轮胎都是世界上最大号的。 它们的轮胎超过4米（13英尺）高，有一个成年人两倍那么高。
