1。 Cork — the thick bark of the cork oak tree (Quercus suber) - is a remarkable material. It is tough, elastic, buoyant， and fire-resistant, and suitable for a wide range of purpos。 It has also been ud for millennia： the ancient Egyptians aled their sarcophagi （stone coffins) with cork, while the ancient Greeks and Romans ud it for anything from beehives to sandals。

译文:软木——软木橡树的厚皮——是一种特别的材料。它具有坚韧、弹性、浮力和防火性能，适用用途广泛。它也被使用了几千年:古埃及人用软木塞封住他们的石棺（石棺)，而古希腊和罗马人则用它来做(几乎）任何东西，从蜂箱到凉鞋。

2．And the cork oak itlf is an extraordinary tree。 Its bark grows up to 20cm in thickness， insulating the tree like a coat wrapped around the trunk and branches and keeping the inside at a constant 20°C all year round. Developed most probably as a defence against forest fires, the bark of the cork oak has a particular cellular structure — with about 40 million cells per cubic centimetre - that technology has never succeeded in replicating。 The cells are filled with air, which is why cork is so buoyant. It also has an elasticity that means you can squash it and watch it spring back to its original size an
d shape when you relea the pressure。
∙大意归纳：软木橡树（cork oak）本身的性能—保温性，防火性，轻巧性（浮力大）,高弹性等.
∙译文：异质同构软木橡树本身就是一棵特别的树.其树皮长大到20厘米厚度，像外套缠绕在树干和树枝上使得树体和外界绝缘，保持在一个全年20°C恒温的状态。可能是进化成为一种防御森林火灾的方法，软木橡树的树皮有一种特殊的细胞结构——每立方厘米大约有4000万个细胞——这种技术从未成功地复制。这些细胞充满了空气，这就是为什么软木塞如此大的浮力。它也富有弹性，这意味着你可以挤压它然后释放压力的时候它会回弹回原样.
