VERBS - PAST TENSE - Exercise 2 Another good way to practice the past tense is to choose a story which is in the present tense and rewrite it. Here is one story you can try: The Story of Little Red Riding Hood Little Red Riding Hood is a little girl. Her grandmother lives I the woods. She is sick. Little Red Riding Hood wants ot take her a basket of food. She walks slowly through the forest. Shesings, whistles and picks flowers. She meets the Big Bad Wolf. He asks, "Where are you going? She replies, "I am going to visit my grandmother. The wolf asks, "Where does she live?" Little Red answers, "Over there." They say goodbye. The Big Bad Wolf goes quickly to grandmother's house. He knocks on the door. The Grandmother says, "Come in." The wolf goes into the house. Grandmother screams when she sees the wolf. The Wolf eats her. Then he puts on a nightgown and gets into bed. Little Red Riding Hood arrives and knocks on the door. The Big Bad Wolf, with a high voice, says: "Come in." Little Red Riding Hood enters the house. She says, "Grandmother, you have very big eyes. The Wolf answers: "So I can see you better." Little Red says, "Grandmother, you have a very big mouth and very big teeth." The wolf jumps up and says, "So I can eat you better." Little Red Riding Hood screams and runs from the wolf. At that moment, a woodcutter hears the screams and comes into the house. He kills the Big Bad Wolf, cuts open his stomach and Grandmother comes out. Little Red Riding Hood and Grandmother thank the woodcutter and everybody is happy.
