Big diggers work to make a new road. They dig up trees and rocks that are in the way.

大型挖掘机正在修建一条新路。 它们挖掉挡路的树木和石块。

Then bulldozers work hard to help build the road. They push the dirt and rocks out of the way.

接着推土机卖力地帮忙修路。 它们把泥土和石块推到一旁。

Then big trucks come to take the dirt away. They put some metal on the road to make it hard.

然后大卡车赶来把泥土运走。 它们在路上铺了一些金属材料 让路面变得坚硬。

Then big rollers work to make the road smooth. They drive on the new road to make it strong.

接着大型压路机把路面压得平整。 它们在新路上来回行驶，让路面更结实。

Big drills dig a hole in the ground to make a tunnel. Then the new road can go into the tunnel.
