Scientists now say that your answers to these questions may depend on your genes. Genes are stretches of DNA that work like an instruction manual for our cells. Genes tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms. So, for example, certain forms of some genes make your eyes blue. Other versions of those genes make your eyes brown. In a similar way, new research suggests that a gene calledperiod3affects how well you function without sleep. The discovery adds to older evidence thatperiod3helps determine whether you like to stay up late or get up early. Theperiod3gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you. Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies ofperiod3. Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers. Results showed that the people with the short form ofperiod3performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off. People with the longperiod3gene, by contrast, fell asleep in just 8 minutes. They also spent more time in deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form. Question: Which of the following statements about theperiod3 is wrong? Options: A: It affects whether you like to stay up late or get up early. B: It comes in two forms: short and long. C: One has either two longs or two shorts of it. D: Your parents determine what particular combination you have.

Article: While their jobs may not be providing them with great excitement, respondents of the Win2000 Salary Survey are saying that they are pretty pleased with their current positions. In fact almost three-quarters of them report a modest to more than average sense of job satisfaction and a little more than ten percent say they are "very satisfied" with their work. So why then does an overwhelming majority of this contented group also report that they are considering changing jobs? The easy and most popular theory says that it's all about the money. IT professionals with highly-prized skills in a very tight job market play salary-stick-em-up by raising their salary demands with each job hop. But this theory calls for a closer look. According to a recent Gartner Group IT market study, enterprises that are experiencing high rates of turnover on average actually offer higher salaries. The Gartner study cites "lack of career development opportunities" as the single most reported reason employees leave companies. Mark Pecoraro, president and CEOof SuccessFactors.com, a workforce management firm, tends to agree: "One of the things we see is the strong desire of these professionals to keep on the cutting edge. These employees are taking control of building their knowledge toolsets and essentially writing their own career tickets." "INDUS Corporation, a Washington, D.C.-based IT firm, is a wonderful place to work," says SearchWin2000 salary survey respondent James Voorhees. Voorhees got his start in IT as an INDUS technical writer. Now, he works as a network administrator, crediting his employer for creating a work environment that let him develop the skills he needed in order to change careers. "An important part of the company culture is an emphasis on employee satisfaction," Voorhees says, pointing to "the company's willingness to let employees try new things ... which has given me several great opportunities to learn and gain experience in networking and software engineering." But INDUS' success relies on a steady... Question: The expression "keep on the cutting edge" can be understood as " _ ". Options: A: maintain good relations with other employees B: avoid suffering resulting from lack of money C: stay in the leading position in the field D: seek harmony between body and spirit

Read the article and select the best answer. Article: Nearly everyone agrees that money doesn't buy as much as it used to, no matter when you want to spend it. This is certainly true of the paper money that passes so quickly through one's hands. But what about coins that seem to do very little except stay in purses and pockets? Unlike notes, metal money becomes more valuable the longer it is held, especially if it is put away where it won't get scratched or worn. Why is this? One reason is that coins, being more durable, fall more readily into a category for collectors. Naturally, the rarer gold pieces must become more valuable as the price of this metal goes up. But, curiously, one of the rarest coins in the world is not made of gold, but of the relatively cheaper silver. In 1840, the United States mint struck 19570 silver dollars. That is what its records show. Today only six of this original number remain and these are unlikely ever to reach the auction market. So what happened to some 19564 large silver coins, not the easiest sort of things to lose? One of the more romantic theories is that they were part of the payment to Napoleon for the American land then known as Louisiana. But they never reached France. Somewhere in the Gulf of Mexico, the ship transporting them was sunk, either by a storm or by pirates. The probable answer to the mystery is that they were melted down -- since the silver value was greater than the actual value of the coin. What really happened to the rest will probably always remain a mystery. What is known is that whoever can come up with one will find himself instantly rich. Question: What really happened to some 19564 large silver coins? Options: A: They were melted down. B: They were sunk in the Gulf of Mexico. C: It is still a mystery. D: They were stolen by pirates.
