单选题Life learning(sometimes called un-schooling or self-directed learning)is one of those concepts that are almost easier to explain by saying what it isn't, than what it is． And that's probably because our own schooled backgrounds have convinced us that learning happens only in a dedicated building on certain days, between certain hours, and managed by a specially trained professional． Within that schooling framework, no matter how hard teachers try and no matter how good their textbooks, many bright students get bored, many slower students struggle and give up or lose their self-respect, and most of them reach the end of the process unprepared to enter into society．They have memorized a certain body of knowledge long enough to rush back the information on tests, but they haven't really learned much, at least of the official curriculum． Life learners, on the other hand, know that learning is not difficult, that people learn things quite easily if they're not compelled and forced, if they see a need to learn something, and if they are trusted and respected enough to learn it on their own timetable, at their own speed, in their own way．They know that learning cannot be produced in us and that we cannot produce it in others—no matter what age and no matter whether we're at school or at home． Life learning is independent of time, location or the presence of a teacher．It does not require mom or dad to teach, or kids to work in workbooks at the kitchen table from 9 to noon from September to June．Life learning is learner-driven．It involves living and learning—in and from the real world．It is about exploring, questioning, experimenting, making messes, taking risks without fear of making mistakes, being laughed at and trying again． Furthermore, life learning is about trusting kids to learn what they need to know and about helping them to learn and grow in their own ways．It is about providing positive experiences that enable children to understand the world and their culture and to interact with it．

单选题Imagine, if you will, the average games player. What do you see? A guy who never grew up? Or a nervous 18-year-old pushing buttons on his controller, lost and alone in a violent onscreen world? Sorry, you lose. The average gamer is starting to look pretty much like the average person. For the first time, according to a US poll commissioned by AOL Games, roughly half of those surveyed, ages 12 to 55, are tapping away at some kind of electronic game—whether on a PC, a cell phone or another handheld device—for an average of three hours every week. The games people play say a lot about who they are. Machines like the Xbox and PlayStation 2 are largely the territory of twenty-something men, who prefer to picture themselves as sports ‘stars and racing drivers. Men 50 and older prefer military games. Teenage girls are much more likely than boys to play games on their phone, while older women make up the majority of people playing card games such as Hearts on line. Is it a good thing, all this time spent on games? Or is it as harmful as television, pulling people ever further from reality? The AOL survey suggests some players are in denial about the extent of their habit. One in 10 gamers find it impossible to resist games; 1 in 4 admits to losing a night’s sleep to play games; and another quarter has been too absorbed to have meals. But don’t think we’re all heading into a world with everyone plugged into, if not totally controlled by, his own game. Quite the contrary: gamers appear to be more engaged with reality than other kinds of couch potatoes. According to a comprehensive survey by the Entertainment Software Association (ESA-whose members, of course, want you to think video games are healthy), gamers spend an average of 23 hours a week volunteering and going to church, concerts, museums and other cultural events. More enthusiastic gamers who play 11 hours a week or more spend ever more time out in the cultural world (34 hours).
