单项选择题

Today my subject is language, or rather the misuse of language. My remarks will, of course, be limited to the English language only. However, they may well apply to other languages also. Why worry about the English language Well, it’s true that English has been developing in scope and color and precision for centuries. It is rich and flexible. Its health is being spoiled by semi-literates with lazy minds and fuzzy thoughts. These semi- literates can’t be grouped under any social classifications. Some are simply the victims of poor education. But a far more influential group occupies important positions in universities, governments and industry, many have degrees attesting to their high intellectual accomplishments. Yet others sit behind type-writers, writing news, advertising copies, speeches, scripts, popular journalism and books.
Part of the linguistic problem is that it’s no easy task to select just the right word or phrase that will precisely convey your meaning. To command language requires many years of patient study and effort. Such effort should begin in the schools. Unfortunately, in most of our present educational institutions in North American, literacy skills are not stressed. Students can learn just about anything — except how to express themselves clearly and effectively.
