We shall live to see the day, I trust, when no man shall build his house for posterity. He might just as reasonably order a durable suit of clothes.., so that his great-grandchildren should cut precisely the same figure in the world... I doubt whether even one public edifice ... should be built of such permanent materials... Better that they should crumble to ruin, once in twenty years or thereabouts, as a hint to the people to reform the institutions which they symbolize. Nathaniel Hawthorne Should buildings be built to crumble to ruin every twenty years? Write an essay in response to this question.

Passage Two In the 1920s, the pioneers of artificial intelligence (AI) predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our housework. But as useful as computers are, they are nowhere close to achieving anything remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of an object, the most elementary of tasks for a ten-month-old kid. A growing group of AI researchers think they know where the field went wrong. The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step programs. A new movement in AI, on the other hand, takes a closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional programs. Rather than digital computers and transistors, some want to work with brain cells and proteins. The results of these early efforts are as promising as they are peculiar, and the new nature-based AL movement is slowly but surely moving to the forefront of the field. Imitating the brain's neural network is a huge step in the right direction, says computer scientist and biophysicist Michael Conrad, but it still missed an important aspect of natural intelligence. 'People tend to treat brain as if it were made up of color-coded transistors. ' He explains, 'But it's not simply a clever network of switches. There are lots of important things going on inside the brain cells themselves.' Specifically, Conrad believes that many of the brains' capabilities stem from the pattern-recognition proficiency of the individual molecules that make up each brain cell. The best way to build an artificially intelligent device, he claims, would be to build around the same sort of molecular skills. Right now, the notion that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow AI rebels could turn out to be the only game in town.

The grammatical words which play so large a part in English grammar are for the most part sharply and obviously different from the lexical words. A rough and ready difference which may seem the most obvious is that grammatical words have 'less 41 ______ meaning', but in fact some grammarians have called 42 ______ them 'empty' words as opposed in the 'full' words 43 ______ of vocabulary. But this is a rather misled way of 44 ______ expressing the distinction. Although a word like the is not the name of something as man is, it is very far away from being meaningless; 45 ______ there is a sharp difference in meaning between 'man is vile' and 'the man is vile', yet the is the single vehicle of this 46 ______ difference in meaning. Moreover, grammatical words differ considerably among themselves as the amount 47 ______ of meaning they have even in the lexical sense. Another name for the grammatical words has been 'little words.' But size is by no mean a 48 ______ good criterion for distinguishing the grammatical words of English, when we consider that we have lexical words as go, 49 ______ man, say, car. Apart from this, however, there is a good deal of truth in what some people say: we certainly do create a great number of 50 ______ obscurity when we omit them. This is illustrated not only in the poetry of Robert Browning but in the prose of telegrams and newspaper headlines.
