A weather map is an important tool for geographers. A succession of three of four maps presents a continuous picture of weather changes. Weather forecasts are able to determine the speed of air masses and fronts; to determine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time.
All students of geography should be able to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States weather Bureau issues information about approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a month it issues a 30-day "outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an analysis of the upper air levels with often set the stage for the development of air masses, fronts, and storms.
Considerable effort is being exerted today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations. Extensive experiments are also in progress for weather modification studies. But the limitations of weather modification have prevented meteorological results except in the seeding of super-cooled, upslope mountainous winds which have produced additional orographical precipitation on the windward side of mountain ranges.

Education is compulsory in Britain, whether at school "or otherwise"; and "other wise" is becoming more popular. In 1999, only 12,000 children were listed as being home-schooled. Now that figure is 20,000, according to Mike Fortune-Wood, an educational researcher. But he thinks that, as most home-taught children never go near a school and are therefore invisible to officialdom, the total is probably nearer 50,000.
As usual, Britain lies between Europe and America. In Germany, home teaching is illegal. In America, it’ s huge: over 1 m children are home-schooled, mainly by religious parents. There are a small minority among British home-educators, who consist mainly of two types: hippyish middle-class parents who dislike schools on principle, and those whose children are unhappy at school.
The growth is overwhelmingly in this second category, says Roland Meighan, a home-education expert and publisher. One reason is that technology has made home-education easier. The internet allows parents to know as much as teachers. It is also a way of organizing get-togethers, sharing tips and outwitting official hassles. That supplements e vents such as the annual home-education festival last week, where 1,600 parents and children enjoyed Egyptian dancing and labyrinth-building on a muddy hillside in Devon.
But a bigger reason for the growth is changing attitudes. Centralisation, government targets and a focus on exams have made state schools less customer friendly and more boring. Classes are still based strictly on age groups, which is hard for children who differ sharply from the average. Mr Fortune-Wood notes that the National Health Service is now far more accommodating of patients’ wishes about timing, venue and treatment. "It’ s happened in health. Why can’t it happen in education" he asks.
Perhaps because other businesses tend to make more effort to satisfy individual needs, parents are getting increasingly picky. In the past, if their child was bullied, not coping or bored, they tended to put up with it. Now they complain, and if that doesn’ t work they vote with their ( children’ s) feet. Some educationalists worry that home-schooling may hurt children’ s psychological and educational development. Home educators cite statistics showing that it helps both educational attainment and the course of grown-up life.
Labour’ s latest big idea in education is "personalisation", which is intended to al low much more flexible timing and choice of subjects. In theory, that might stem the drift to home--schooling. Many home-educators would like to be able to use school facilities occasionally--in science lessons, say, or to sit exams. But for now, schools, and the of ficials who regulate them, like the near-monopoly created by the rule of "all or nothing".

A:Britain is the focal point in terms of geography. B:The extremes of "otherwise" can not be found in UK. C:Germany embraces the growth of second category. D:Religious parents in America forbid "otherwise".

Passage 3 An invisible border divides those arguing for computers in the classroom on the behalf of students’ career prospects and those arguing for computers in the classroom for broader reasons of radical educational reform. Very few writers on the subject have explored this distinction -- indeed, contradiction -- which goes to the heart of what is wrong with the campaign to put computers in the classroom. An education that aims at getting a student a certain kind of job is a technical, education, justified for reasons radically different from why education is universally required by law. It is not simply to raise everyone’s job prospects that all children are legally required to attend school into their teens. Rather, we have a certain conception of the American citizen, a character who is incomplete if he cannot competently assess how his livelihood and happiness are affected by things outside of himself. But this was not always the case; before it was legally required for all children to attend school until a certain age, it was widely accepted that some were just not equipped by nature to pursue this kind of education. With optimism characteristic of all industrialized countries, we came to accept that everyone is fit to be educated. Computer- education advocates forsake this optimistic notion for a pessimism that betrays their otherwise cheery outlook. Banking on the confusion between educational and vocational reasons for bringing computers into schools, computered advocates often emphasize, the job prospects of graduates over their educational achievement. There are some good arguments for a technical education given the fight kind of student. Many European schools introduce the concept of professional training early on in order to make sure children are properly equipped for the professions they want to join. It is, however, presumptuous to insist that there will only be so many jobs for so many scientists, so many businessmen, so many accountants. Besides, this is unlikely to produce the needed number of every kind of professional in a country as large as ours and where the economy is spread over so many states and involves so many international corporations. But, for a small group of students, professional training might be the way to go since well - developed skills, all other factors being equal, can be the difference between having a job and not. Of course, the basics of using any computer these days are very simple. It does not take a lifelong acquaintance to pick up various software programs. If one wanted to become a computer engineer, that is, of course, an entirely different story. Basic computer skills take -- at the very longest -- a couple of months to learn. In any case, basic computer skills are only complementary to the host of real skills that are necessary to becoming any kind of professional, It should be observed, of course, that no school, vocational or not, is helped by a confusion over its purpose.

A:included as an auxiliary course in school B:highlighted in acquisition of professional qualifications C:mastered through a life -long course D:equally emphasized by any school, vocational or otherwise
