The color red often means danger -- and by paying attention, 1   can be prevented. At railroad crossings, flashing red lights warn cars to stay back. A red light at a traffic intersection tells cars to stop, so  2 don't run into other cars.
 
In the future, the color red also may help prevent danger3construction sites. Thanks to new work by engineers, bridge supports- or other kinds of materials—could one day contain a color-changing material. It will turn red 4a structure collapses or falls   5  A tiny molecule may make a big difference in future warning systems.
 
A polymer6   a color-changing molecule called a mechanophore turns red seconds before it snaps. The technology may one day allow damage to materials or structures to be easily  7   .

The secret behind the color-changing material is a particular type of molecule. A molecule is a group of atoms held together by8bonds. Molecules come in all shapes and sizes, and make up 9you can see, touch or feel. How a molecule behaves depends on what kinds of atoms it contains, and how they're held together.

When a polymer containing a color-changing molecule called a mechanophore is about to breaks, it produces a color. When a polymer with mechanophore molecules becomes "injured" or10, one of the mechanophore bonds breaks and the material turns red. "It's a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. "We're 11 up this one bond, and it changes color. " Sottos and her team tested the color-changing polymers in their lab. The test12 proved encouraging.

There is a way to get rid of the red color: 13. When a bright light is shone on the mechanophore, the broken bond is fixed - and the red color disappears. This "self-healing" may be a problem for engineers. They need to use the color-changer in big construction projects that will be   14   , in sunlight. And sunlight will make the mechanophore's warning system useless.

Sottos and her fellow scientists still have15   work to do before the color-changing molecules can be used outside the lab.

2010职称英语理工完型新增文章-第3篇参考译文
第三篇   看见红色意味着危险在前方
红色常常表示危险，通过引起注意能够防止意外。在铁路交叉口，闪烁的红灯警告车辆靠后。在交通十字路121的红灯告诉车辆停止前进，所以就不会发生车祸。
在未来，建筑工地的红色可能也可以防止危险。多亏了工程师的新作和桥梁支柱等其他的材料，它们有一天能包含一种会变换颜色的物质，该物质能够在建筑物倒塌或之前变成红色。一个小小的分子就会对报警系统起到很大影响。
一个聚合物包含一种变换颜色的分子叫做机械响应性聚合物，它能够在在聚合物断裂前几秒钟变成红色。这项技术能够很容易地发现材料或建筑物的损坏。
这个变换颜色的物质的秘密就是一种特别的分子。一个分子是由化学键把一群原子组合起来。分子有各种各样的形状和大小，所以能够组成你所见到的、摸到的和感觉到的任何东西。一个分子怎样表现取决于它包含什么样的原子，和他们被怎样组合起来。
当包含变换颜色分子的机械响应性聚合物要断裂的时候，它会产生一种颜色。当一个包含机械响应性聚合物分子的聚合物“受损害”或者变弱的时候，其中的一个机械响应性聚合物键破碎，这个物质变成红色。“这是一个很简单的检测方法。”Nancy Sottos说，她是为这个项目工作的科学家之一。Sottos和她的团队在他们的实验室测试这种变换颜色的聚合物，测试的结果非常鼓动人心。
有一种方法可以除去红色：光。当强光照射在机械响应性聚合物上，断裂的键被修复——红色就会消失。这种“自我修复”或许给工程师们带来问题。他们需要在露天的，也就是暴露在阳光下的大建筑工程外面使用换色器。阳光会使机械响应性聚合物的报警系统不起作用。
要让这些变色分子在实验室以外也能使用，Sottos和她的同事们还有许多工作要做。
