As regards social conventions, we must say a word about the English class system. This is an embarrassing subject for English people, and one they tend to be ashamed of, though during the present century class-consciousness has grown less and less. But it still exists. Broadly speaking, it means there are two classes, the "middle class" and the "working class" (We shall ignore for a moment the old "upper class", since it is extremely small in numbers; but some of its members have the right to sit in the House of Lords, and some newspapers take a surprising interest in their private life.) The middle class consists chiefly of businessmen and professional people of all kinds. The working class consists chiefly of manual and unskilled workers.

The most obvious difference between them is in their accent. Middle-class people use slightly varying kinds of "received pronunciation" which is the kind of English spoken by BBC announcers and taught to overseas pupils. Typical working-class people speak in many different local accents which are generally felt to be rather ugly and uneducated. One of the biggest barriers of social equality in England is the two-class education system. To have been to a so-called "public school" immediately marks you out as one of the middle class. The middle classes tend to live a more formal life. Their midday meal is "lunch" and they have a rather formal evening meal called "dinner", whereas the working man's dinner, if his working hours permit, is at midday, and his smaller, late-evening meal is called supper.

It has been government policy to reduce class distinctions. Working-class students commonly receive a university education and enter the professions, and working-class incomes have grown so much recently. However, regardless of one's social status, certain standards of politeness are expected of everybody, and a well-bred person is polite to everyone he meets, and treats a laborer with the same respect he gives an important businessman. Servility inspires both embarrassment and dislike. Even the word "sir", except in school and in certain occupations (e.g. commerce, the army etc.) sounds too servile to be commonly used.

The "upper class" in England today______.

A．are extremely small in number so that media pays no attention to them

B．still uses old words like "sir" in their everyday life

C．can sits in the House of Lords

D．refers only to the royal family

In the 1950s, 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're 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 computer 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 AI 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 misses an important aspect of natural intelligence. "People tend to treat the 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 brain's 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 it around the same sort of molecular skills.

Right now, the option 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 author says that the powerful computers of today ______.

A．are capable of reliably recognizing the shape of an object

B．are close to exhibiting humanlike behavior

C．are not very different in their performance from those of the 50's

D．still cannot communicate with people in a human language

第6题

It is hardly necessary for me to cite all the evidence of the depressing state of literacy. These figures from the Department of Education are sufficient- 27 million Americans cannot read at all, and a further 35 million read at a level that is less than sufficient to survive in our society.

But my own worry today is less that of the overwhelming problem of elemental literacy than it is of the slightly more luxurious problem of the decline in the skill even of the middle-class reader, of his unwillingness to afford those spaces of silence, those luxuries of domesticity and time and concentration, that surround the image of the classic act of reading, it has been suggested that almost 80 percent of America's literate, educated teenagers can no longer read without an accompanying noise (music) in the background or a television screen flickering at the corner of their field of perception. We know very little about the brain and how it deals with simultaneous conflicting input, but every common-sense intuition suggests we should be profoundly alarmed. This violation of concentration, silence, solitude goes to the very heart of our notion of literacy; this new form. of part-reading, of part-perception against background distraction, renders impossible certain essential acts of apprehension and concentration, let alone that most important tribute any human being can pay to a poem or a piece of prose he or she really loves, which is to learn it by heart. Not by brain, by heart; the expression is vital.

Under these circumstances, the question of what future there is for the arts of reading is a real one. Ahead of us lie technical, psychic, and social transformations probably much more dramatic than those brought about by Gutenberg, the German inventor in printing. The Gutenberg revolution, as we now know it, took a long time; its effects are still being debated. The information revolution will touch every fact of composition, publication, distribution, and reading. No one in the book industry can say with any confidence what will happen to the book as we've known it.

The picture of the reading ability of the American people, drawn by the author, is ______.

A．rather bleak

B．fairly bright

C．very impressive

D．quite encouraging
