TEXT C It is hard to conceive of a language without nouns or verbs. But that is just what Riau Indonesian is, according to David Gil, a researcher at the Max Planck Institute for Evolutionary .Anthropology, in Leipzig. Dr. Gil has been studying Riau for the past 12 years. Initially, he says, he struggled with the language, despite being fluent in standard Indonesian. However, a breakthrough came when he realized that what he had been thinking of as different parts of speech were, in fact, grammatically the same. For example, the phrase "the chicken is eating" translates into colloquial Riau as "ayam makan". Literally, this is "chicken eat". But the same pair of words also have meanings as diverse as "the chicken is making somebody eat", or "somebody is eating where the chicken is". There are, he says, no modifiers that distinguish the tenses of verbs. Nor are there modifiers for nouns that distinguish the definite from the indefinite. Indeed, there are no features in Riau Indonesian that distinguish nouns from verbs. These categories, he says, are imposed because the languages that western linguists are familiar with have them. This sort of observation flies in the face of conventional wisdom about what language is. Most linguists are influenced by the work of Noam Chomsky---in particular, his theory of "deep grammar". According to Dr. Chomsky, people are born with a sort of linguistic template in their brains. This is a set of rules that allows children to learn a language quickly, but also imposes constraints and structure on what is learnt. Evidence in support of this theory includes the tendency of children to make systematic mistakes which indicate a tendency to impose rules on what turn out to be grammatical exceptions (e. g. "I dided it" instead of "I did it"). There is also the ability of the children of migrant workers to invent new languages known as creoles out of the grammatically incoherent pidgin spoken by their parents. Exactly what the deep grammar consists of is still not clear, but a basic distinction between nouns and verbs would probably be one of its minimum requirements. Dr. Gil contends, however, that there is a risk of unconscious bias leading to the conclusion that a particular sort of grammar exists in an unfamiliar language. That is because it is easier for linguists to dis cover extra features in foreign languages--for example tones that change the meaning of words, which are common in Indonesian but do not exist in European languages--than to realize that elements which are taken for granted in a linguist’s native language may be absent from another. Despite the best intentions, he says, there is a tendency to fit languages into a mould. And since most linguists are westerners, that mould is usually an Indo-European language from the West. It needs not, however, be a modern language. Dr. Gil’s point about bias is well illustrated by the history of the study of the world’s most widely spoken tongue. Many of the people who developed modern linguistics had had an education in Latin and Greek. As a consequence, English was often described until well into the 20th century as having six different noun cases, because Latin has six. Only relatively recently did grammarians begin a debate over noun cases in English. Some now contend that it does not have noun cases at all, others that it has two while still others maintain that there are three or four cases. The difficulty is compounded if a linguist is not fluent in the language he is studying. The process of linguistic fieldwork is a painstaking one, fraught with pitfalls. Its mainstay is the use of "informants" who tell linguists, in interviews and on paper, about their language. Unfortunately, these informants tend to be better-educated than their fellows, and are often fluent in more than one language. ______ cannot serve as evidence of Noam Chomsky’s theory of "deep grammar".

A. "He never forgaved her for teasing him."
B. "She beganed to feel a sense of panic."
C. "Sheeps were grazing on the hillside."
D. "There are a desk and two chairs here."

TEXT D In 1981 Kenji Urada, a 37-year-old Japanese factory worker, climbed over a safety fence at a Kawasaki plant to carry out some maintenance work on a robot. In his haste, he failed to switch the robot off properly. Unable to sense him, the robot’s powerful hydraulic arm kept on working and accidentally pushed the engineer into a grinding machine. His death made Urada the first recorded victim to die at the hands of a robot. This astounding industrial accident would not have happened in a world in which robot behavior was governed by the Three Laws of Robotics drawn up by Isaac Asimov, a science fiction writer. The laws appeared in 1, Robot, a book of short stories published in 1950 that inspired a Hollywood film. But decades later the laws, designed to prevent robots from harming people either through action or inaction, remain in the realm of fiction. With robots now poised to emerge from their industrial cages and to move into homes and workplaces, roboticists are concerned about the safety implications beyond the factory floor. To address these concerns, leading robot experts have come together to try to find ways to prevent robots from harming people. "Security, safety and sex are the big concerns," says Henrik Christensen, chairman of the European Robotics Network at the Swedish Royal Institute of Technology in Stockholm, and one of the organisers of the new roboethics group. Should robots that are strong enough or heavy enough to crush people be allowed into homes Should robotic sex dolls resembling children be legally allowed These questions may seem esoteric but in the next few years they will become increasingly relevant, says Dr. Christensen. According to the United Nations Economic Commission for Europe’s World Robotics Survey, in 2002 the number of domestic and service robots more than tripled, nearly outstripping their industrial counterparts. Japanese industrial firms are racing to build humanoid robots to act as domestic helpers for the elderly, and South Korea has set a goal that 100% of households should have domestic robots by 2020. In light of all this, it is crucial that we start to think about safety and ethical guidelines now, says Dr. Christensen. So what exactly is being done to protect us from these mechanical menaces "Not enough," says Blay Whitby, an artificial-intelligence expert at the University of Sussex in England. This is hardly surprising given that the field of "safety-critical computing" is barely a decade old, he says. But things are changing, and researchers are increasingly taking an interest in trying to make robots safer. One approach, which sounds simple enough, is to try to program them to avoid contact with people altogether. But this is much harder than it sounds. Getting a robot to navigate across a cluttered room is difficult enough without having to take into account what its various limbs or appendages might bump into along the way. Regulating the behavior of robots is going to become more difficult in the future, since they will increasingly have self-learning mechanisms built into them, says Gianmarco Veruggio, a roboticist at the Institute of Intelligent Systems for Automation in Genoa, Italy. As a result, their behavior will become impossible to predict fully, he says, since they will not be behaving in predefined ways but will learn new behavior as they go. Blay Whitby thinks that "safety-critical computing" ______.

A. is in its infancy.
B. has its heyday,
C. undergoes rapid development.
D. can hardly be improved.
