Reading 7B SEEING THE IMPOSSIBLE Can you believe everything you see? Not always! Sometimes our minds and our eyes make mistakes and get confused. This may be because we are looking at an optical illusion. The word optical means "related to sight"—the way we see things. An illusion is something that looks different from the way it really is. In short, an optical illusion is a trick that our eyes play on us. Look at these optical illusions and compare what you see with what your classmates see. The way we see things is often personal, so not everyone will see things the same way. 1. Are the lines straight? At a first look, most people say "No." But if you compare the lines against an object with a straight edge, you'll see otherwise. The small circles in the squares help create the illusion. 2. What color are the squares? Square 1 is clearly gray. But what about square 2? Is it white? Is it light gray? You may not believe it, but squares 1 and 2 are exactly the same color. Your eyes see the colors, but your brain notices the shadow made by the apple. It therefore decides that the square in the shadow is a lighter color than it really is. 3. Are the circles moving? If you look closely at this picture, the circles may appear to move. Of course, this is impossible. How can a picture move? When we see circle-in-circle shapes, like in car wheels, they are usually moving. Our brains are used to seeing these shapes move. When our eyes see this shape, our mind decides that the image is moving. Other scientists believe the illusion of movement is caused by the movements of our eyes as we look at the different colors and patterns of the picture.

阅读7B 看到不可能 你能相信你所看到的一切吗？ 并非总是如此！ 有时我们的头脑和眼睛会犯错误并感到困惑。 这可能是因为我们看到的是一种视错觉。 光学这个词的意思是“与视觉有关”——我们看待事物的方式。 幻觉是指看起来与实际情况不同的东西。 简而言之，视错觉是我们的眼睛对我们耍的花招。 看看这些视觉错觉，并将你所看到的与你的同学所看到的进行比较。 我们看待事物的方式往往是个人的，所以不是每个人都会以同样的方式看待事物。 1.这些线是直的吗？ 乍一看，大多数人都说“不” 但如果你把这些线和一个有直边的物体进行比较，你会发现情况并非如此。 方块中的小圆圈有助于创造错觉。 2.正方形是什么颜色的？ 正方形1明显是灰色的。 但是广场2呢？ 它是白色的吗？它是浅灰色的吗？ 你可能不相信，但方块1和2的颜色完全相同。 你的眼睛看到了颜色，但你的大脑注意到了苹果留下的阴影。 因此，它决定阴影中的正方形颜色比实际颜色浅。 3.圆圈在动吗？ 如果你仔细看这张照片，圆圈可能会移动。 当然，这是不可能的。 图片如何移动？当我们看到圆圈中的圆圈形状时，就像汽车车轮一样，它们通常在移动。 我们的大脑习惯于看到这些形状在移动。 当我们的眼睛看到这个形状时，我们的大脑会认为图像在移动。 其他科学家相信运动的错觉 是由我们看图片的不同颜色和图案时眼睛的运动引起的。
