小树要为展品写说明。柔软的纸，为什么能从一盆纸浆中出现？Mia needs labels for the exhibit. How can a flexible sheet emerge from a tub of pulp?
第 1 步：先把纤维分散Step 1: Disperse the fibres
从纸张里的细丝开始。Start with the tiny strands in paper.
纸主要由纤维交织而成。纸浆是分散在水里的纤维。纤维来自不同植物或旧纸。它不是一整片剥下的树皮。Paper mainly consists of interwoven fibres. Pulp disperses fibres in water. They may come from plants or recovered paper. A sheet is not simply a piece of peeled bark.
第 2 步：捞起一层网络Step 2: Lift a fibre network
水很多，怎样得到薄薄一张？How does watery pulp become a thin sheet?
网帘托住一层纤维。水从缝隙流走。压榨和干燥继续去水。纤维之间的结合撑住纸张。A screen catches a layer of fibres. Water drains through its gaps. Pressing and drying remove more water. Bonds between the fibres hold the sheet together.
第 3 步：复制知识也有成本Step 3: Sharing knowledge has costs
有了纸，知识就自动普及吗？Does paper automatically spread knowledge?
纸让记录更方便携带。还需要书写、印刷与阅读教育。造纸也消耗水和能源。回收能利用旧纤维，但并非无限循环。Paper makes records easier to carry. Writing, printing, and literacy still matter. Making paper uses water and energy. Recycling reuses fibres, but not without limits.

拖动去水进度，看湿层变成纤维网。百分比只表示动画进度。Remove water to reveal the fibre network. Percentages describe animation progress only.
一句话记住它：Remember it:造纸是把分散纤维重新结成薄片。Papermaking reunites dispersed fibres into a thin sheet.
纸主要由纤维交织而成。Paper mainly consists of interwoven fibres.网帘托住一层纤维。A screen catches a layer of fibres.纸让记录更方便携带。Paper makes records easier to carry.
成纸机制：较高把握。造纸早期史来自多种文物与记载，不能等同于一人一刻发明。High confidence in sheet formation. Early papermaking history combines artifacts and records rather than one isolated invention.
