公园快开放了，门口还差一段连接道路。安安从围栏外看见几辆不同的工程车：“今天谁先来，谁最后来呢？”

The park was almost ready, but a connecting road was missing. An'an saw several machines beyond the fence. “Who goes first, and who comes last today?”

公园快开放了，门口还差一段连接道路。安安从围栏外看见几辆不同的工程车：“今天谁先来，谁最后来呢？”

The park was almost ready, but a connecting road was missing. An'an saw several machines beyond the fence. “Who goes first, and who comes last today?”

林工程师拿出没有字的小图卡：运料、摊铺、压实。“今天是一次接力。”安安把卡片排好：“我来记住顺序！”

Lin brought wordless picture cards: deliver, pave, compact. “Today's a relay.” An'an arranged them. “I'll remember the order!”

先检查路下面的基础。标高、平整、排水和需要的处理都准备好，才能铺上面。妈妈说：“漂亮的路面，也需要可靠的底下。”

First came checks of the base: level, shape, drainage and required treatment. “An attractive surface needs sound support underneath,” Mom said.

运料车送来沥青混合料。里面有石料，也有起黏结作用的沥青。它和给平台用的混凝土不同，可不能认成同一种材料。

The truck brought asphalt mix: stone bound with bitumen. It was different from the concrete used for the platform; the two were not interchangeable.

今天用的是热拌材料，施工区域很烫，必须隔开。安安站在参观区捏捏妈妈的手：“我们只看，不靠近、不伸手。”

Today's hot-mix material made the work area hot and off-limits. An'an held Mom's hand in the visitor area. “We look without going close or touching.”

绿色摊铺机张着宽宽的料斗，像在等一份大午饭。运料车按现场指挥慢慢到位，确认配合好，才向料斗卸料。

The green paver's broad hopper seemed to await a giant lunch. Under site guidance, the truck approached slowly and unloaded only when everything was aligned.

哗啦，材料落进料斗。安安问：“它吃进去以后，从哪里出来？”林工程师让她看看摊铺机身后的方向。

The mix poured into the hopper. “Where does it come out after going in?” An'an asked. Lin pointed toward the back of the paver.

机器里的输送装置把材料送向后面，再由螺旋分料器向左右分开。这样，宽宽的路面才都有材料铺上。

Conveyors carry the mix rearward, and augers distribute it sideways. That supplies material across the full paving width.

后面的熨平板像一位细心的整理员，帮助铺出设定的宽度、厚度和平整度。不是安安家里熨衣服的那一块小板子哦。

The screed behind carefully shapes the planned width, thickness and evenness. It is not the little iron used for clothes at home!

摊铺机保持合适的速度，一条黑亮的新路慢慢伸出来。安安用手指在空气里画长线：“这条线，要一直接得顺顺的。”

At a suitable steady speed, the paver left a fresh dark strip. An'an drew a line in the air. “Let's keep it smooth and connected.”

下一辆运料车还没到，大家先联系确认。材料供应要衔接好，突然断断续续，会给摊铺带来麻烦。安安说：“接力不能只顾自己跑！”

The next delivery had not arrived, so the team checked in. Supply needed coordination; interruptions could complicate paving. “A relay isn't just about your own turn!” An'an said.

现场按照材料状态和施工方案调整安排。需要暂停，就把停工和接缝处理做好；不是随便等一等，再接上就算完成。

The team adjusted the work to material condition and the paving plan. Any pause needed proper stopping and joint treatment, not simply waiting and starting again.

运输接上了，摊铺继续向前。接缝处也要认真处理，让新铺的部分和前面的部分按要求连好。安安说：“拼图的边边也很重要。”

With delivery restored, paving continued. Joints needed care so sections connected as required. “Puzzle edges matter, too,” An'an said.

压路机跟上来，按材料和温度要求压实。摊铺机负责铺，压路机负责压；看着平整，还要把里面做好。

The roller followed, compacting according to material and temperature requirements. The paver laid it; the roller compacted it. A smooth look was only part of the job.

工作人员检测路面的情况，也检查边缘、排水和接缝。安安问：“所以最后一辆车走了，还没到我们上场的时候？”

Workers checked the surface, edges, drainage and joints. “So even when the last machine leaves, it isn't our turn yet?” An'an asked.

还要等冷却、检查合格，并由现场确认开放。围栏没有撤，大家就继续从安全的临时通道走。妈妈说：“我们也帮接力守好最后一步。”

The road needed cooling, successful checks and approval to open. While barriers remained, everyone used the safe temporary path. “We help by respecting this final step,” Mom said.

回家后，安安把玩具车排成队：前面送材料，中间铺，后面压。她推到一半停下来：“前面的还没准备好，后面的先等等。”

At home, An'an lined up toys: deliver, pave, compact. Halfway through, she paused. “If the first stage isn't ready, the next one waits.”

妈妈用卡纸做一条路，安安一段段拼好。哪条接缝最整齐？哪里漏了一小块？她拿起小纸片：“我来补上这个空缺！”

Mom made paper road pieces, and An'an fitted them together. Which joint was neatest? Where was a gap? “I'll fill this space!” she said.

现在请你来当故事里的小调度员：石料刚送到，应该请摊铺机先铺，还是让行人先走？安安把公园门口的小人留在围栏外。

Be the story's little planner: when material arrives, should paving happen first, or should people walk on it? An'an kept the toy visitors outside the barrier.

道路开放了，公交车稳稳停在公园站。安安和妈妈从人行道走进公园：“谢谢接力小队，把回家的路和公园连起来啦！”

When the road opened, a bus stopped at the park stop. An'an and Mom entered from the sidewalk. “Thank you, relay team, for connecting our neighborhood to the park!”

前一道做好，后一道接稳，合作让长长的路连起来。

Prepare each stage and support the next so teamwork can connect a long road.

给大人的共读锦囊

这次不考背诵，练一种生活能力

这本想陪孩子练什么

理解有先后关系的合作。

共读时别急着说

不把施工流程背诵当作考核，让孩子用自己的话讲接力。

可以这样问

运料、摊铺、压实怎样接上？
车走了为什么还不能马上踩新路？

今天试试看

用纸片拼一条路，找空缺和接缝，再用玩具车演一遍运料、摊铺、压实。

4–5 岁：每次听几个动作就好，允许配音、指图和重复最喜欢的一页。

6–8 岁：请孩子解释一次遇到困难后的选择，比较两种车的分工，不要求背术语。
