Sparky’s Adventure Farid was doing his best to steer clear of the movers until suddenly, he remembered his goldfish. “What about Sparky?” he asked. His parents stared at each other, open-mouthed, as his dad clapped his hand to his forehead. “Plenty of room for the fish,” the head mover offered. “You can’t be serious,” Mom said. “How can you get a goldfish from Lebanon to Detroit, Michigan?” “The same way as everything else: on the boat!” Six weeks later at the new house, a mover handed Sparky’s bowl to Farid. There was a letter too, with pictures. “Dear Farid,” the letter began, “I’ve had quite an adventure. First, I sailed on a small cargo ship from Lebanon to Spain. Here’s a picture of me and the captain. Then I moved to a large freighter that sailed from Spain to New York. Here’s a picture of me with the crew. Then I moved to a barge on the Hudson River. That took me through the Erie Canal to another small boat, which crossed Lake Erie to Detroit. Here’s that boat. Finally, a truck brought me to the door. Thanks for not forgetting me!” Đọc đoạn hội thoại trên và trả lời những câu hỏi sau: Where was the new house? What did a mover hand Farid along with Sparky’s bowl?
