1. Angela wasn't singing a song, (dance) To complete this sentence, we need to use the verb in brackets (dance) to form the past continuous tense. In the past continuous tense, we use the verb "be" (in this case, "wasn't") followed by the present participle of the verb (in this case, "dancing"). So the correct sentence is: "Angela wasn't singing a song, she was dancing." 2. I was cooking potatoes, (fish) Using the same pattern as before, we need to use the verb in brackets (fish) to form the past continuous tense. So the correct sentence is: "I was cooking potatoes, not fish." 3. The boys were watching a film, (the news) Again, using the verb in brackets (the news) to form the past continuous tense, the correct sentence is: "The boys were watching a film, not the news." 4. My mother wasn't washing the dishes, (iron the clothes) Applying the same pattern, we form the past continuous tense with the verb in brackets (iron the clothes). So the correct sentence is: "My mother wasn't washing the dishes, she was ironing the clothes." 5. He was building the house, (garage) Using the verb in brackets (garage) to create the past continuous tense, the correct sentence is: "He was building the house, not the garage." 6. They were gathering berries, (mushrooms) Applying the same pattern, we form the past continuous tense with the verb in brackets (mushrooms). So the correct sentence is: "They were gathering berries, not mushrooms." 7. You weren't listening to music, (read the book) Using the verb in brackets (read the book) to create the past continuous tense, the correct sentence is: "You weren't listening to music, you were reading the book." 8. Ben was repairing his bike, (his car) Applying the same pattern, we form the past continuous tense with the verb in brackets (his car). So the correct sentence is: "Ben was repairing his bike, not his car." In summary, by using the past continuous tense, we can describe actions that were happening in the past at a specific moment. The pattern for forming the past continuous tense is "subject + was/were + present participle of the verb." By applying this pattern and replacing the verb in brackets with the appropriate present participle verb, we can correctly complete the given sentences.
