5 阅读理解。 It was early afternoon and the harbor (海港) was quiet. Mr Bates, the keeper of the lighthouse (灯塔), went to the village. He left his daughters Rebecca and Abigail to look after the lighthouse. As Rebecca was about to prepare some water for the evening meal, she noticed a strange ship coming to the harbor. It stopped and lowered two little boats, which turned and started toward land: At that time people feared every ship they did not know, for the year was 1814 and America and Britain were at war. Rebecca and Abigail held their breath to see what these two boats would do. Closer and closer they came, until finally they entered the harbor. They were full of British soldiers! No help was to be seen. What could they do? How could they warn the town soldiers? They had no boat, and there would be no time to run to the village. Rebecca thought fast and then she had an idea. Calling to Abigail to follow, she ran to the room where the guns were stored. But instead of reaching for the guns, she took hold of the fife (军笛 ) and the drum(战鼓 ). Then the two young women ran along the wooded path to the shore (海岸). Hiding behind tall trees, they started to play the fife and the drum. Abigail beat out Roll Call. Rebecca joined in with Yankee Doodle. Soon Rebecca saw the boats had stopped! The girls went on playing. A moment later, a flag was raised on the warship-the signal for the boats to return. Once everyone was on board, the enemy ship set sail for the open sea. The British were fooled, and the" American Army of Two" won the day. 1. Why did Rebecca take the fife and the drum instead of the guns? A. She would leave the guns for the soldiers. B. She would welcome the British soldiers. C. She loved to play the fife and the drum. D. She wanted to frighten the British soldiers away. 2. The underlined part " American Army of Two" in the last paragraph probably refers to____. A. Rebecca and Abigail B. the two British boats C. the fife and the drum D. the two town soldiers 3. The British ship left the harbor because____.
