• Unit 1: Now and Then – Present and Past Tense

    Unit 1 introduces you to two tenses used in Standard American English: simple present and simple past. In English, we use tenses to tell us when something happens. Is an event happening now? Did it already happen? The way we use verbs, called the tense of the verb, tells us this. In this unit, you will learn how to recognize tenses, what makes them different, and when each is used. You’ll learn about the verb "to be" and how it is used in a sentence. Finally, you will practice identifying tenses and writing your own short phrases in past, present, and present perfect tense. 

    Completing this unit should take you approximately 2 hours.
