You're busy filling out the application form. for a position you really need; let's assume you once actually completed a couple of years of college work or even that you completed your degree.
Isn't it tempting to lie just a little, to claim on the form. that your diploma represents a Harvard degree? Or that you finished an extra couple of years back at State University? More and more people are turning to utter deception like this to land their job or to move ahead in their careers, for personnel officers, like most Americans, value degrees from famous schools. A job applicant may have a good education anyway, but he or she assumes that chances of being hired are better with a diploma from a well-known university. Registrars at most well-known colleges say they deal with deceitful claims like these at the rate of about one per week.
Personnel officers do check up on degrees listed on application forms, then, if it turns out that an applicant is lying, most colleges are reluctant to accuse the applicant directly. One Ivy League school calls them "impostors"; another refers to them as "special cases" one well-known West Coast school, in perhaps the most delicate phrase of all, says that these claims are made by "no such people."
To avoid outright lies, some job-seekers claim that they "attended" or "were associated with" a college or university. After carefully checking, a personnel officer may discover that "attending" means being dismissed after one semester. It may be that "being associated with" a college means that the job seeker visited his younger brother for a football weekend. One school that keeps records of false claims says that the practice dates back at least to the turn of the century—that's when they began keeping records, anyhow.
If you don't want to lie or even stretch the truth, there are companies that will sell you a phony diploma. One company, with offices in New York and on the West Coast, will put your name on a diploma from any number of nonexistent colleges. The price begins at around twenty dollars for a diploma from "Smoot State University." The prices increase rapidly for a degree from the "University of Purdue." As there is no Smoot State and the real school in Indiana is properly called Purdue University, the prices seem rather high for one sheet of paper.
The main idea of this passage is that ______.
A.employers are checking more closely on applicants now
B.lying about college degrees has become a widespread problem
C.college degrees can now be purchased easily
D.employers are no longer interested in college degrees

Viewed from a star in some other comer of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun. While our neighbors Venus and Mars would reflect a fairly even glow, Earth would put on a little show. Earth's light would brighten and dim as it spins, because oceans, deserts, forests and clouds—which are all too small to be seen from such a distance-reflect varying amounts of sunlight. The variations, it turns out, are so strong and distinctive that surprising amount of information could be taken from a simple ebb and flow of light. Scientists at Princeton University and the Institute for Advanced Study conducted a detailed study of Earth's reflections as a way for human scientists to learn about distant planets that may be like our own.
(2) "If you looked at our solar system from far away, and you looked at the terrestrial planets--Mercury, Venus, Earth and Mars--one of the quickest ways to see that Earth is unique is by looking at the light curve," said Ed Turner, professor of astrophysics and a co-author of the study. "Earth has by far the most complicated light curve." The standard thinking in the field had been that most of the information about an Earth-like planet would come from spectral analysis, a static reading of the relative component of different colors within the light, rather than a reading of changes over time. Spectral analysis would reveal the presence of gases such as water vapor, carbon dioxide and oxygen, in the planet's atmosphere, looking at the change in light over time docs not replace spectral analysis, but it could greatly increase the amount of information scientists could learn, said Turner. It may indicate, for example, the presence of weather, oceans, ice or even plant life.
"Earth would put on a little show" means: as it spins, ______.
A.Earth is a more active planet than Venus and Mars
B.Earth reflects a brighter light curve than Venus and Mars
C.Earth shows oceans, deserts, forests and clouds, while Venus and Mars don't
D.Earth reflects sunlight in an ebb-and-flow manner
