单选题The familiar sounds of an early English summer are with us once again. Millions of children sit clown to SATs, GCSEs, AS-levels, A-levels and a host of lesser exams, and the argument over educational standards starts. Depending on whom you listen to, we should either be letting up on over-examined pupils by abolishing SATs, and even GCSEs, or else making exams far more rigorous. The chorus will reach a peak when GCSE and A-level results are published in August. If pass rates rise again, commentators will say that standards are falling because exams are getting easier. If pass rates drop, they will say that standards are falling because children are getting lower marks. Parents like myself try to ignore this and base our judgements on what our children are learning. But it's not easy given how much education has changed since we were at school. Some trends are encouraging—education has been made more relevant and enthuses many children that it would have previously bored. My sons' A-level French revision involved listening to radio debates on current affairs, whereas mine involved rereading Molière. And among their peers, a far greater proportion stayed in education for longer. On the other hand, some aspects of schooling today are incomprehensible to my generation, such as graps in general knowledge and the hand-holding that goes with ensuring that students leave with good grades. Even when we parents resist the temptation to help with GCSE or A-level coursework, a teacher with the child's interests at heart may send a draft piece of work back several times with pointers to how it can be improved before the examiners see it. The debate about standards persists because there is no single objective answer to the question "Are standards better or worse than they were a generation ago?" Each side points to indicators that favour them, in the knowledge that there is no authoritative definition, let alone a measure that has been consistently applied over the decades. But the annual soul-searching over exams is about more than student assessment. It reveals a national insecurity about whether our education system is teaching the right things. It is also fed by an anxiety about whether, in a country with a history of upholding standards by ensuring that plenty of students fail, we can attain the more modern objective of ensuring that every child leaves school with something to show for it.

单选题In this monumental work the entire storehouse of the world's art is surveyed.

单选题In 1798 the political economist Malthus predicted that in time mankind would face starvation, having outgrown the available food supplies. Today, a century and a half later, there are still experts who forecast the same global disaster unless urgent measures are taken to prevent it. By the end of the present century there may well be over five thousand million people living on this globe, ail increase of over fifty per cent of today's figure. In order to keep pace with this increase in mankind the farmers of the world would have to step up their production of food by at least two per cent every year. Such a rate of increase has never been maintained in any country by conventional methods of agriculture, despite modern mechanization and the widespread use of fertilizers. There are no large worthwhile reserves of potential farmland, remaining, and good fertile land is continually being diverted to industrial use. Moreover, erosion of the soil takes a constant toll. Intensive research, carried out over many years in all manner of climatic conditions, has produced a revolutionary method of growing crops without using any soil at all. Hydroponics, as this technique is called, may well be the answer to all our food worries. Already it has accomplished wonders in producing huge crops. Hydroponics was once a complicated and expensive business; now it is well out of the experimental stage. Labor costs are far lower than when normal methods of agriculture are employed. In fact, it is a completely automatic system. There is no hard manual work, no digging or plowing, and no weeding to speak of. Yields can be far higher than they are in soil.

单选题 When an invention is made, the inventor has three possible courses of action open to him: he can give the invention to the whole world by publishing it, keep the idea secret, or patent it. A granted patent is the result of a bargain struck between an inventor and the state, by which the inventor gets a limited period of monopoly and publishes full details of his invention to the public after that period terminates. only in the most exceptional circumstances is the life-span of a patent extended to alter this normal process of events. The longest extension ever granted was to Georges Valensi; his 1939 patent for color TV receiver circuitry was extended until 1971 because for most of the patent's normal life there was no colour TV to receive and thus no hope of reward for the invention. Because a patent remains permanently public after it has terminated, the shelves of the library attached to the patent office contain details of literally millions of ideas that are free for anyone to use and, if older than half a century, sometimes even re-patent. Indeed, patent experts often advise any other inventer's right is to plagiarize a dead patent likewise, because publication of an idea in any other form permanently invalidates further patents on that idea, it is traditionally safe to take ideas from other areas of print. Much modem technological advance is based on these presumptions of legal security. Anyone closely involved in patents and inventions soon learns that most "new" ideas are, in fact, as old as the hills. It is their reduction to commercial practice, either through necessity or dedication, or through the availability of new technology, that makes news and money. The basic patent for the theory of magnetic recording dates back to 1886. Many of the original ideas behind television originate from the late 19th and early 20th century. Even the Volkswagen rear engine car was anticipated by a 1904 patent for a cart with the horse at the rear.
