Practice forming questions and pronouncing them correctly in part four of Basic English Grammar - The Simple Past Tense. Questions are formed based on the subject and the object from part three. Scrambled sentences are given to put in the correct order. Yes/no questions are discussed as well as the issue of who versus whom and the verb "to be." The questioning section ends with an audio scenario and fill-in-the-blank sentences. About halfway through, the focus switches to how to pronounce the ending -ed. The scenario from part three is shown once more, reviewing the past tense verbs and their pronunciations.
