   18 The Bounding Main 第十八章 浩瀚的海洋

  Imagine trying to live in a world dominated by dihydrogen oxide1, 请你想像一下,你能不能生活在一个由一氧化二氢主宰的世界里。
  a compound that has no taste or smell and is so variable in its properties that it is generally benign2 but at other times swiftly lethal3. 那是一种无色无味的化合物,性质极为多变,一般情况下比较温和,但有时候一下子可以致命。
  Depending on its state, it can scald you or freeze you. 它可以灼伤你,也可以冻坏你,这取决于它处于什么状态。
  In the presence of certain organic molecules4 it can form carbonic acids so nasty that they can strip the leaves from trees and eat the faces off statuary. 要是存在某种有机分子,它可以形成碳酸。碳酸简直可恶之极,会使树叶掉个精光,会侵蚀雕像的表面。
  In bulk, when agitated5, it can strike with a fury that no human edifice6 could withstand. 要是数量很大,而且受到剌激,它就会发起猛烈的袭击,人类的任何建筑物都不是它的对手。
  Even for those who have learned to live with it, it is an often murderous substance. 即使对于那些已经学会与它一起过日子的人来说,它也往往充满危险。
  We call it water. 我们把这东西称之为水。
  Water is everywhere. 哪里都有水。
  A potato is 80 percent water, a cow 74 percent, a bacterium7 75 percent. 一个马铃薯80%是水,一头牛74%是水,一个细菌75%是水。
  A tomato, at 95 percent, is little but water. 一个西红柿95%是水,几乎全是水。
  Even humans are 65 percent water, making us more liquid than solid by a margin8 of almost two to one. 连人也65%是水,因此我们身上的液体和固体之比差不多是2:1。
  Water is strange stuff. 水是一种古怪的东西。
  It is formless and transparent9, and yet we long to be beside it. 它没有形状,晶莹透明,然而,我们渴望待在它的身边。
  It has no taste and yet we love the taste of it. 它没有味道,我们却爱尝尝它的味道。
  We will travel great distances and pay small fortunes to see it in sunshine. 我们千里迢迢,花上好多的钱,就是为了去看一眼它在阳光下闪耀的情景。
  And even though we know it is dangerous and drowns tens of thousands of people every year, we can't wait to frolic in it. 尽管我们知道它很危险,每年要淹死成千上万个人,我们还是迫不及待地要去水里泡一泡。
  Because water is so ubiquitous we tend to overlook what an extraordinary substance it is. 由于水是无处不在的,因此我们往往不在意它是一种极不寻常的物质。
