四、阅读理解。(2025·江苏泰州靖江靖城中学八校联盟调研)
Have you ever poured water onto your shirt right before an important event? Usually, clothes darken in colour when they get wet. It would certainly be nice if the water didn't change the colour of the clothes so much. But sadly, this isn't how things work. So why do clothes often appear darker when they get wet?
Before understanding this question, we should first take a quick look at how we “see” colours. Take a red shirt as an example. When it is hit by the light from the sun, it absorbs(吸收) different wavelengths(波长) of light, except for the red light wavelength. The red light wavelength is reflected(反射) to our eyes. That is why the shirt appears red to us.
Now let's return to the wet shirt. When the light hits a wet shirt, it has to pass through the water on the shirt. The light that should be reflected by the shirt is reabsorbed(重吸收) by the water. This means less light will be sent to our eyes. As a result, the shirt looks “darker”.
But remember, sometimes a wet shirt can seem brighter from some special angles(角度) of observation. The surface(表面) of a shirt is usually rough. Adding water to it makes it smoother. A smooth surface reflects light in a different way from a rough surface. So you may see a small and bright reflection of the light from a certain angle. So usually, a wet shirt will be darker than a dry one, but it can also appear “shinier” at times.

答案： 1. C 【点拨】根据“Take a red shirt as an example.”可知，作者通过一个例子来解释人们如何“看见”颜色。故选 C。2. B 【点拨】根据“The light that should be reflected by the shirt is reabsorbed(重吸收) by the water.”可知，一些光会被水重新吸收。故选 B。3. A 【点拨】根据“So usually, a wet shirt will be darker than a dry one, but it can also appear ‘shinier’ at times.”可知，it 指代的是“湿衬衫”。故选 A。4. D 【点拨】根据“This means less light will be sent to our eyes. As a result, the shirt looks ‘darker’.”可知，进入我们眼睛的光线会变少，所以衬衫看起来颜色更深，由此推断，进入我们眼睛的光线越多，那么衬衫看起来就会越亮。故选 D。5. B 【点拨】根据“So why do clothes often appear darker when they get wet?”并通读全文可知，本文主要在解释为什么衣服湿了颜色会变深。故选 B。
