高中英语阅读专项试题

　　高中英语阅读专项试题原文：

　　Why do we have in a camera a lens(镜头)instead of a simple hole?

　　The reason can be seen from the figures(图像).

　　In Figure 1, the hole is small. Rays of light from a point (P1)outside reach a very small part ofthe wall opposite, and we see there a small point. But when the hole is bigger, as in Figure 2,rays from the point(P2)can cover a larger part of the wall opposite, and we don't see a clearpoint, Rays from other points(Q) outside can also fall on the same place inside. Therefore thepicture is not clear when the hole is big and it is not bright when the hole is small because veryvery little light can pass through it.We can get better result with a lens. If the lens is made inthe shape shown in Figure 3, all the rays of light from the point(P3) are thrown on point(P')inside. The picture which we see, therefore, is clear, and it is also bright because more light canpass through a lens than through a small hole.
