Hiểu bài
Review 1 revises Units 1–3. Pronunciation covers weak auxiliary forms, contractions, and consonant-to-vowel linking. Vocabulary revisits health, generations, and cities. Grammar reviews the past simple and present perfect, stative and linking verbs, and must, have to, and should. Skills pages include listening about life expectancy and reading about the generation gap. The reading prompts address social change, limited family interaction, parents working long hours, and comparisons between children. Writing asks for a 120–150-word opinion essay. Exercises remain unanswered for independent review.
