2、sing, therefore, that Americans have valued education for its monetary value. The belief is widely spread in the United States that the more schooling people have, the more money they will earn when they leave school.

3、degree, or a professional degree such as medicine or law following the undergraduate degree.

7、on, regretted not finishing high school so much that he occasionally lied about it. He told Richard Reeves about his pride in graduating from high school, but then a few minutes later he said, “I wasnt telling the truth about high school. I never finished. I quit in the twelfth grade to take a job.
8、Its funny after all these years, I still lie about it. Because the fact is, I still think it was a stupid thing to do.

The principle
14、 of image formation was discovered in early Greek Times. Later it was realized that the eye itself has a lens and that an image is, in fact, formed on the retina, the rear inside surface of the eyeball. Some man inside a cave or a darkened room noticed that light entering through a small hole in the
15、 wall formed an image on the far wall. It was observed that if you enlarge the hole, the image blurred and disappeared. On the other hand, the smaller the hole, the sharper the image-down to a certain diameter after which making the hole smaller makes the image worse again.The function of a pinhole
16、is to screen out all light rays except those coming in a perfectly straight line from the object, thus improving the sharpness of the image. After passing through a point the rays again spread out a little bit, and the size of the image formed will depend upon how far back the wall, screen, or film
17、is from the pinhole.The full exploitation of this phenomenon had to wait for the development of the lens, which gathered in a much larger number of light rays and still brought them to form an image, just as the pinhole did, but with a difference: in a pinhole camera, the light rays form an image th
18、at is equally sharp regardless of the distance to the film. When a lens is used, there may be a choice of planes of focus determined by adjusting the lens-to-film distance. Each plane is located some distance behind and relatively parallel to the lens.Actual blown glass was developed early in Egypti
19、an times, and the first lens may have been the bottom of a wine bottle. However, the first deliberate grinding of lenses did not take place until the thirteenth century, and the art did not become established until the sixteenth century. A book on the grinding and polishing of lenses was issued by B
20、. Battista della Porta in 1589, but it was not until 1611 that Kepler compared a lens of glass to the lens in the eye and showed that rays from each point of an object were brought to a focus at each corresponding point of an image on the retina. Then, in 1619, Scheiner demonstrated the actual forma
