But nature has another way to create colour, called “structural colour”. Structural colour comes from tiny shapes on the surfaces of things like wings, feathers or shells. 1.___ Now scientists have used nanotechnology (纳米技术) to make paint with structural colour. F 1 2 3 4 5 课 后 习 题 94 2.___ They were trying to create a special mirrored surface. But they found super-small clumps of aluminum atoms (铝原子团块) on the surface. The researchers were upset because these small clumps messed up the mirror. Then they realised that the clumps made colour when light hit them. They decided to turn their discovery into paint. All the colour in the new paint comes from aluminum. There are tiny aluminum pieces and then even smaller nanoparticles (纳米颗粒) that create the colour. The nanoparticles C 1 2 3 4 5 课 后 习 题 don't really produce the colour. They simply reflect back single colour. 3.___ Because the new paint doesn't have pigments, the paint is so light that it could reduce the amount of fuel used by planes and cars. 4.___ It would only take 1.3kg of structural paint to do the same job. 5.___ In regular paint, pigments break down and fade over time. That's not true for structural colour. Once we paint something with structural colour, it should stay for centuries. D E A 1 2 3 4 5 课 后 习 题 What's more, the new paint doesn't heat up like regular paint. That's true even for darker colour. The new paint can keep surfaces up to 16.6 cooler than normal paint. Using the paint on buildings in cities could help cool cities and reduce the electricity spent on air conditioning. A.The new paint has several other advantages. B.Structural paint could save as much money as possible. C.Researchers weren't really planning on making paint. D.The size of them determines which colour gets reflected. 1 2 3 4 5 课 后 习 题 E.Generally, it takes about 500kg of paint to cover an airplane. F.Normally, we never see the shapes because they're so small. G.It will probably be a while before you can use structural colour. 【文章大意】本文是一篇说明文。文章主要说明了科学家利用大自 然制作出新型油漆的方法和这种油漆的优点。 1 2 3 4 5 课 后 习 题 1.___ F [解析] 由上文“Structural colour comes from tiny shapes on the surfaces of things like wings, feathers or shells.”可知,下面要说与 “微小形状”有关的内容,F选项(通常情况下,我们永远看不到这些形状, 因为它们太小了。)能承接上文,符合文意。F项中的small与空前的tiny 相对应。故选F。 1 2 3 4 5 课 后 习 题 99 2.___ C [解析] 由下文“They were trying to create a special mirrored surface.
