The victory made Jackson a national hero and helped him to be elected president in 1828 and 1832.     New Orleans was the battle of the war of1812; as a matter of fact, the war had been over for more than two weeks when the battle was fought. U.S. and British officials meeting in Ghent (根特), Belgium, signed a treaty (条约) on Dec．24, 1814, but the news didn’t cross the Atlantic until seven weeks later. Had news of the treaty arrived before the British attacked, there would never have been a battle of New Orleans and Jackson might never have been elected president of the United States. There were those, however, who did not think highly of Jackson’s victory. On March 31, 1815, a judge of the United States District Court of the city of New Orleans fined (罚款) Jackson $1,000 for contempt(轻视) because he had declared martial law(宣布军管) during his defense. Twenty - nine years later, on Jan. 8, 1844, the House of Representatives decided to return the money to Jackson with interest at 6%.     根据短文判断正(T)误 (F): 1. Andrew Jackson became famous for his victory in the battle of New Orleans. 2. Because they were defeated in the New Orleans, the British signed a treaty with the U. S. and surrendered. 3. The U.S. people admired Jackson so much that he was twice elected president. 4. The war wouldn’t have come to an end if there had not been the battle in New Orleans. 5. The two sides decided to make peace and signed a treaty. But three weeks later, the battle of New Orleans broke out.
