Article: Time and how we experience it have always puzzled us.Physicists have created fascinating theories, but their time is measured by a pendulum and is not psychological time, which leaps with little regard to the clock or calendar.As some-one who understood the distinction observed, " _ Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age.They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass.For example, a day at the office flies compared with a day at the beach.Since most of us spend fewer days at the beach and more at the office as we age, an increase in structured tune could well be to blame for why time seems to speed up as we grow older. Expectation and familiarity also make time seem to flow more rapidly.Almost all of us have had the experience of driving somewhere we've never been before. Surrounded by unfamiliar scenery, with no real idea of when we'll arrive, we experience the trip as lasting a long time. But the return trip, although exactly as long, seems to take far less time. The _ of the outward journey has become routine. Thus taking a different route on occasions can often help slow the clock. When was become as identical as identical as beads on a string, they mix together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day--to stop time, so to speak. Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems so full and long is that these are the days of learning and discovery. For many of us, learning ends when we leave school, but this doesn't have to be. Question: Why do units of time fly faster as we grow older? Options: A: Our sense of time changes. B: We spend less time at the beach. C: More time is structured and scheduled. D: Time is structured with too many appointments.

Q: Read the article and select the best answer. Article: This is not a typical summer camp. Michelle Pawlaw and eight other teenage girls are participating in the three--day camp offered by the Arlington County Fire Department located just outside Washington. Firefighter Clare Burley is in charge of the program,who said the purpose is to try to get young women interested in considering the fire service as a career. The free-of-charge,overnight camp is designed to let the girls experience what firefighters do to protect the community. That includes some rigorous activities such as moving a fire victim. "I dindn't think I could pull that 170 pound body with a friend, but I was actually able to do it." she said. They take classes and learn how to climb the ladder on a fire truck, operate emergency tools and rescue an injured person. They also do their share of cleaning the firehouse and the equipment. "Every week without fail on a Saturday,the job is to wash all the equipment. And we wanted the girls to see this is what we do. This is a typical day in a firehouse,"she said. Firefighting is still a male-dominated service,but Burley says with 22 women on its force of 320 the Arlington County Fire Department is above the national average of 4.5 percent. She joined the department seven years ago. "We do everything that the guys do to the same standard. We are tested to the same standard. We are expected to operate at the same standard,"she said. Most of the girls say they had never thought about becoming a firefighter. but the camp was a great learning experience. "I think it is definitely not a job that only men can do.

Read the article and select the best answer. Article: Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory. According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in. " We've always known that caffeine has cognitive-enhancing effects , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo or a 200-milligram caffeine tablet. To check the caffeine levels of their test subjects, the research team took saliva samples from them before they took their tablets and again one, three and 24 hours after- wards. Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day. The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier. The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same. "We also know that caffeine is associated with...
