(10 points) The making of weathervanes (devices fixed on the top of buildings to show directions of the wind) is an ancient skill, going back to early Egyptian times. Today the craft is still very much alive in the workshop that Graham Smith has set up. He is one of the few people in the country who make handcut weathervanes. Graham39。 ability to [A] find a single solution from textbooks to problem she confronts. [B] finish a regular engineer39。s what engineering is about finding a way to solve problems while working under many types of restrictionspolitical, financial and environmental ones, for instance. Although online experiments can enhance an engineer39。 their governing principle is epitomized in the title of a speech by a distinguished member of the profession: Can Native Speakers of a Language Make Mistakes? Within the profession of linguist there are of course warring factions, but on this conception of language as a natural growth with which it is wrong to tamper they are at one. In their arguments one finds appeals to democratic feelings of social equality (all words and forms are equally good) and individual freedom (anyone may do what he likes with his own speech). These assumptions further suggest that the desire for rightness, the very idea of better or worse in speech, is a hangover from aristocratic and oppressive times. To the linguists, change is the only ruler to be obeyed. They equate it with life and accuse their critics of being clock reversers, enemies of freedom, menaces to life. Somewhat inconsistently, the linguists produce dictionaries in which they tell us that a word or an expression is standard, substandard, colloquial, archaic, slang, or vulgar. How do they know? They know by listening to the words people use and by noticingin conversations, newspaper, and bookshow and by whom these words are used. Usage, then, is still real and various, even though the authorities refuse to point openly to a set of words and forms as being preferable to others. Standard gets around the difficulty of saying best or right. 31. Most Americans believe that [A] the language they use should be constantly improved. [B] language rules do exist and hence should be obeyed. [C] everyone has the right to use the language as he likes. [D] grammar, vocabulary and old phrases must be made easier. 32.

Against this majority view is the doctrine of an aggressive minority, who make up for their small number by their great learning and their place of authority in the world of scholarship. They are the professional linguists who deny that there is such a thing as correctness. The language, they say, is what anybody and everybody speaks. Hence there must be no interference with what they regard as a product of nature。s researcher. Health experts are not ready to list the foods that will keep cancer at bay, but some broad outlines of an anticancer diet are taking shape. Beta carotene might not be the key. But fruits and vegetables seem to help. So along with giving up tobacco and limiting alcohol consumption, the best way to prevent a broad range of cancers, given the current state of medical knowledge, is to eat more fruits and vegetables. That sort of diet will help you stay trim and prevent heart disease anywayso if, against all odds, it turns out to have no effect on cancer, it certainly can39。s no surprise that the relationship between diet and cancer is still largely a matter of educated guessworkand in many cases, the guesses have turned out to be wrong. Take the much publicized link between highfat diets and breast cancer, for example. Women who live in Western countries, where highfat diets are the norm, tend to have high breastcancer rates. Even more telling: women of Japanese ancestry who live in the , get the disease six times more often than their grandmothers and greatgrandmothers in Japan. Yet a huge recent study of 90 000 women has refuted the breast cancerfat link. A similar process of educatedguessanderror led people to load up on the nutritional supplement beta carotene in the early 1990s. Scientists noted that those who eat lots of fruits and vegetables tend to get less cancer and speculated that carotenoidsthe same antioxidant substances that seem to protect against heart diseasewere responsible. In particular, they focused on beta carotene, the most abundant and mon carotenoid, as the most likely to prevent cancer. Yet a series of targeted studies in Finland and the . showed that beta carotene supplements don39。 it39。 targets. [C] outnumber elephants and hippos in the future.
