2、y to that old saw. Thanks to sophisticated imaging technology and a number of longitudinal (纵向的) studies, were learning that the teen years are a period of crucial brain development subject to a host of environmental and genetic factors. This emerging research sheds light not only on why teenagers a
3、ct the way they do, but how the experiences of adolescencefrom rejection to binge drinking (酗酒)can affect who we become as adults, how we handle stress, and the way we bond with others.One of the most important discoveries in this area of study, says Dr. Frances Jensen, a neuroscientist at Harvard,
4、is that our brains are not finished maturing by adolescence, as was previously thought. Adolescent brains “are only about 80 percent of the way to maturity,“ she said at the annual meeting of the Society for Neuroscience in November. It takes until the mid-20s, and possibly later, for a brain to bec
5、ome fully developed.An excess of gray matter (the stuff that does the processing) at the beginning of adolescence makes us particularly brilliant at learningthe reason were so good at picking up new languages starting in early childhoodbut also particularly sensitive to the influences of our environ
6、ment, both emotional and physical. Our brains processing centers havent been fully linked yet, particularly the parts responsible for helping to check out impulses and considering the long-term results of our actions. “Its like a brain thats all cheered up not knowing where it needs to go,“ says Jen
7、sen.Its partially because of this developmental timeline that a teen can be so quick to think of a stinging remark, or a biting insult, and so uninhibited in firing it off at the nearest unfortunate targeta former friend, perhaps, or a bewildered parent. The impulse to hurl an insult is there, just
8、as it may be for an adult in a stressful situation, but the brain regions that an adult might rely on to stop himself from saying something cruel just havent caught up.In a paper published last year in the Journal of the American Academy of Child researchers advise that working long hours for a year

This doesnt mean that high school students shouldnt work at all, and in todays economic environment, many need to work part-time to help their families or (53) for college.Researchers note that parents, educators and employers should be (

12、gly easy to move from place to place, our inability to communicate with one another gives rise to numerous misunderstandings and makes real contact between people of different nationalities impossible. Many attempts have been made to overcome this problem, but they have all failed. The fear of forei
13、gn influence and domination rules out the universal acceptance of any one of the existing major languages.Linguists(语言学家) have succeeded in making their artificial languages extremely simple so that they would be easy to learn, but their efforts seemed doomed from the start. The reason for this is t
14、hat there is no real incentive (动机) to learn an artificial language. There is nothing to guarantee that everybody is willing to make efforts; there is no assurance that the learner will have an adequate return for his toil. When people today undertake to learn a foreign language, they are not intere
15、sted only in speaking it.Mastery of a language makes available to the learner a great deal of worthwhile literature and many current publications. This is the biggest stumbling-block (障碍) of all for the artificially-constructed tongue. Having no literature of its own, all it can offer is a limited n
16、umber of translations which are valueless in themselves. Moreover, constant use over a long period would bring into being many “national“ dialects and the language would thus defeat its own purpose.Another serious objection is the fact that a language is shaped by use rather than by design. It is a
17、living thing which is constantly growing and changing. It takes hundreds of years before it can acquire richness and depth. In an artificial language, however, the meanings of works are rigidly defined. Inflexibility makes for an absence of subtlety, so that no really fine meaning can be conveyed. T
18、hough this quality might be admirable for scientific publications, it greatly impedes (阻碍) the formation of any significant literature. Latin(拉丁语) words are ideal in this respect, for it was a “dead“ language with a literature; an artificial one is “dead“ from the start. This makes it likely that ex

24、sted. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, whether you have just eaten and what sort of drinks you have had. Some people might reach their limit after only about three standard drinks.In
25、 fact, your driving ability can be affected by just one or two drinks.
