造纸术是中国四大发明之一，发明时期于汉朝西汉时期，改进时期于汉朝东汉时期。中国是世界上最早养蚕织丝的国家。中国古代劳动人民以上等蚕茧抽丝织绸，剩下的恶茧、病茧等则用漂絮法制取丝绵。漂絮完毕，篾席上会遗留一些残絮。当漂絮的次数多了，篾席上的残絮便积成一层纤维薄片，经晾干之后剥离下来，可用于书写。这种漂絮的副产物数量不多，在古书上称它为赫蹏或方絮。Papermaking is one of the four great inventions in China， which was invented in Han Dynasty and Western Han Dynasty， and improved in Han Dynasty and Eastern Han D China is the first country in the world to raise silkworms and weave In ancient China， the cocoons of the working people and above were drawn into silk， and the rest of the evil cocoons and sick cocoons were made into silk floss by After bleaching， some residual flocs will be left on the When the number of bleaching flocks is increased， the residual flocs on the grid will accumulate into a fiber sheet， which will be peeled off after being dried and can be used for The number of by-products of this kind of bleaching is small， and it is called Herculum or Square Flour in ancient 发展历史远古以来，中国劳动人民就已经懂得养蚕、缫丝。秦汉之际以次茧作丝绵的手工业十分普及。这种处理次茧的方法称为漂絮法，操作时的基本要点包括，反复捶打，以捣碎蚕衣。这一技术后来发展成为造纸中的打浆。此外，中国古代常用石灰水或草木灰水为丝麻脱胶，这种技术也给造纸中为植物纤维脱胶以启示。纸张就是借助这些技术发展起来的。历史上关于汉代的造纸技术的文献资料很少，因此难以了解其完整、详细的工艺流程。后人虽有推测，也只能作为参考之用。总体来看，造纸技术环节众多，因此必然有一个发展和演进的过程，绝非一人之功。它是中国劳动人民长期经验的积累和智慧的结晶。
写作思路：罗列出中国的四大发明，写出这些发明的伟大之处，使用简单的英文句子描写出这些。正文：There are four world famous inventions in China， one is gunpowder， the other is compass， the third is printing and the fourth is 我国有世界著名的四大发明，一是火药，二是指南针，三是印刷术，四是造纸术。This makes our ancient China become an ancient 这让我们中国古代成了文明古国。China's four great inventions have played an irreplaceable role in various fields of science and 中国的四大发明在各个科技领域中起到了不可替代的重要作用。G Gunpowder was invented by 火药，火药是我们发明的。What does gunpowder bring us?火药给我们带来什么东西呢？It brought fireworks， firecrackers， fireworks， mining， and 带来了礼花、带来了鞭炮、用于制造烟花爆竹、用于采矿，还有用于航天事业的发展。Up to now， gunpowder has played an important role in our 到今天为止火药在我们的历史上发挥着巨大的作用。
