  • Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:

    Most languages have several levels of vocabulary that may be used by the same speakers. In English, at least three have been identified and described. Standard usage includes those words and expressions understood, used, and accepted by a majority of the speakers of a language in any situation regardless of the level of formality. As such, these words and expressions are well defined and listed in standard dictionaries. Colloquialisms, on the other hand, are familiar words and idioms that are understood by almost all speakers of a language and used in informal speech or writing, but not considered acceptable for more formal situations. Almost all idiomatic expressions are colloquial language. Slang, however, refers to words and expressions understood by a large number of speakers but not accepted as appropriate formal usage by the majority. Colloquial expressions and even slang may be found in standard dictionaries but will be so identified. Both colloquial usage and slang are more common in speech than in writing. Colloquial speech often passes into standard speech. Some slang also passes into standard speech, but other slang expressions enjoy momentary popularity followed by obscurity. In some cases, the majority never accepts certain slang phrases but nevertheless retains them in their collective memories. Every generation seems to require its own set of words to describe familiar objects and events. It has been pointed out by a number of linguists that three cultural conditions are necessary for the creation of a large body toàn thân of slang expressions. First, the introduction and acceptance of new objects and situations in the society ; second, a diverse population with a large number of subgroups ; third, association among the subgroups and the majority population. Finally, it is worth nothing that the terms standard, colloquial, and slang exist only as abstract levels for scholars who study language. Only a tiny number of the speakers of any language will be aware that they are using colloquial or slang expressions. Most speakers of English will, during appropriate situations, select and use all three types of expressioins .

    In most of the earliest books for children, illustrations were an afterthought. But in the Caldecott toy books, which first appeared in 1878, they were almost as important as the lines of text, and occupied far more space in the book. One can almost read the story from the dramatic action in the pictures. Since then, thousands of successful picture books have been published in the United States and around the world. In the best, the words and illustrations seem to complement each other perfectly. Often a single person is responsible for both writing and illustrating the book. One of the greatest, and certainly one of the most successful, illustrator-authors was Dr. Seuss, whose real name was Theodor Geisel. His first childrens book, And to Think That I Saw It on Mulberry Street, hit the market in 1937, and the world of childrens literature was changed forever. Seusss playful drawings were a perfect complement to his engaging stories and unforgettable characters. In 1957, Seusss The Cat in the Hat became the first book in Random Houses best-selling series, Beginner Books, written by Seuss and several other authors. Thes e combine outrageous illustrations of people, creatures, and plants, and playful stories written in very simple language. Dr. Seuss is not the only well-known author-illustrator, of course. There is Max Sendak, who wrote and illustrated Where the Wild Things Are, the story of a little boy named Max, who becomes king of the fierce ( but funny ) creatures that live in the Land of the Wilds Things. Robert McCloskey produced both the richly textured illustrations and delightful story of a family of ducks living in downtown Boston, Make Ways for Ducklings. Some books are produced by a collaborative author artist team. Author Margaret Wise Brown combined with illustrator Clement Hurd to produce two delightful books loved by very young children, Goodnight Moon and The Runaway Bunny. Another example is the husband-and-wife team of writer Audrey Wood and illustrator Don Wood, who were responsible for King Bidgoods in the Bathtub and The Napping House. Wordless and nearly wordless picture books have become popular. With a little help, three and four-year-olds can follow the sequence of events, and they can understand the stories suggested in them. The marvel of books with few or no words is that they allow children and their parents the opportunity to tell and retell the same stories over and over in their own words. One of the most charming examples of a wordless book is Jan Omerod’s Sunshine. Barbara Bergers Grandfather Twilight and David Weisners Tuesday are examples of books containing only a few words. U.S. publishers have also drawn on illustrators from other countries whose original, imaginative works have brought their different visions to American childrens books. Among them are Leo Lionni from Italy, Feodor Rojankovsky from Russia, and Taro Yashimi from Nhật Bản .
