Who It’s For: (Self-)Teachers & Helpers at Intermediate & Advancing Proficiency Levels Who Want “All There Is to Know” about Present Perfect (Continuous) Forms + Participial Verb Vocabulary, with Their Sentence Patterns, Meanings, & Functions
Why It’s Useful: Even when fully contextualized, Grammar-Text Units from earlier times tended to “put it all down in black & white” in linear sequence. Unit 14 of Scenario, Volume Two starts with a presentation of “Complaints” in printed business letters. In order, it offers pedagogy and practice in uses of The Present Perfect: Statements, Questions, Short Answers; Past Participle Forms; Activity at Unspecified Past Times; the Present Perfect Continuous; and Activity Up to the Present Time. Download and try it. Material like this has worked in the (distant & recent) past and has been achieving results for a long time.
What You’ll Do:
 In the page 175 Scenario: Complaints, the last name of the “letter writer,” Quejada, is the past participle of a Spanish verb for “complain.” Noting their variety of Present Perfect (Continuous) Verb Phrases, read both letters. In Sections 1a-1c, show that you get the meanings of the sentences. In 2-2e, practice constructing them. In 3-3h, learn and apply the Past Participle Forms of regular and the main irregular English verbs. Create and play learning games with Simple Form vs. Participial Verb Cards.
 In 4-4b on pages 184-186, understand and make Present Perfect sentences about “Activity at Unspecified Past Times.” Do Sections 5-5h on the Present Perfect Continuous: Activity Up to the Present, contrasting it with the Present Perfect. Demonstrate what you can do with the grammar in the several “Talking It Over” and “Writing It Down” activities.
 Check your understanding of the relevant time frame with Section 6: The Perfect Tenses: Summary on page 194. Complete remaining Exercises and Activities.
