"I realized that I would not move up in my career without a degree. " A generation ago, Jonaitis would have been a rarity(稀罕)in college. Today about 6 million people aged 25 or older are studying in American institutions of higher learning. Whether they are returning to improve job skills or for the love of learning, adults no longer see age as a deterrent(障碍). Most people jump at the opportunity to do something new. Some of them make changes they'd been thinking about all their lives. Others return to school out of economic necessity. New developments in neuroscience(神经科学)and psychology are confirming that there are few age limits on how much the brain can absorb and for how long--if you stay active. Continuing to learn keeps us mentally in shape and able to learn more. On mental tests, experts discovered, half to two-thirds of the people in their 70s were as intellectually quick as people in their 30s. Those who fell below average tended to be people who had not made a lifelong habit of reading. They also were less physically active. Many adult students say learning is easier for them today. They bring different skills to the classroom, and they're less upset if something goes wrong. They have a real thirst, a real desire to learn.

单选题Internet use appears to cause a drop in psychological health, according to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more bad feelings and loneliness than those who was online less frequently, the two-year study showed. Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the Net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others. The fact that Internet use reduces time available for family and friends may account for the drop in psychological health, researchers hypothesized (推测). Faceless, bodiless "virtual"(虚的) communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that exposure(暴露) to the wider world through the Net makes users less satisfied with their lives. "But it" s important to remember this is not about the technology, it" s about how it is used," says psychologist Christine Riley of Intel, one of the study" s sponsors (发起人). "It really points to the need for considering social factors in terms of how you design applications and services for technology."

Here are some places you can exchange foreign currency for U.S. currency. Your Bank In many cases you can purchase U. S. currency for your trip from a bank. Banks tend to have higher exchange rates than some currency exchange businesses. Before you purchase currency from a bank, check the currency change rates for that day so you can compare the rate the bank is giving and determine if it"s a good offer. There is a fee involved in withdrawing foreign currency from your bank. The Airport Currency exchange businesses can be found at most international airports, so you can purchase U. S. currency either before you board your flight or at the U.S. airport on arrival. Note that U. S. airports typically have fewer currency exchange counters than travelers are accustomed to seeing in other parts of the world. If the airport you are flying into is not in a major U.
