（单词翻译）

 Our modern world, with its skyscrapers1, suspension bridges, and automobiles2, relies heavily on steel. If you own an aging car however, you know firsthand that steel has one annoying problem: it rusts4. All steel, that is, except stainless5 steel. What keeps this remarkable6 material, used commonly in kitchen sinks and cookware, from rusting7? Steel’s main ingredient is iron. When steel rusts, its iron combines with oxygen and reverts8 to iron ore, the raw state from which it came. As this happens, the steel turns brown and begins to crumble9. There are many ways to protect steel from corrosion10. Steel is sometimes painted or greased, or coated with a metal that is less likely to rust3. Sometimes a metal that is MORE likely to rust is attached. Known as a sacrificial metal, this works by drawing the corrosion process away from the steel. For example, bars of zinc11 are attached to the hulls13 of some ships. The zinc rusts heavily, but the steel hull12 stays relatively14 safe.
