This guide is designed to sensitize both the novice and experienced teacher to the problems Vietnamese students are likely to have in learning the grammatical structures of English. The guidelines and suggestions presented here relate principally to the structures of English which differ markedly from parallel structures of Vietnamese, and which therefore are especially difficult for Vietnamese students. Among the areas discussed are suffixes, the plural -s, the possessive -s, the -er comparative and -est superlative, -ly adverbs, -ing forms used as nouns, -ing forms used as adjectives, tenses, "be" sentences, questions, negatives, and articles. The bulletin also includes a section on adapting English textbooks to meet the needs of Vietnamese students, as well as a listing of useful reference books on both the English and Vietnamese languages.
