Banks are not ordinarily prepared to pay out all accounts(账，账户); they rely on depositors (储户) not to demand payment all at the same time. If depositors should come to fear that a bank is not safe, that it cannot pay off all its depositors, then that fear might cause all the depositors to appear on the same day. If they did, the bank could not pay all accounts. However, if they did not all appear at once, then there would always be enough money to pay those who wanted their money when they wanted it. Mrs. Elsie Vaught has told us of a terrifying bank run that she experienced. One day in December of 1925 several banks failed to open in a city where Mrs. Vaught lived. The other banks expected a run the next day, and so the officers of the bank in which Mrs Vaught worked as a teller had enough money on hand to pay off their depositors. The officers simply told the tellers to pay on demand. The next morning a crowd gathered in the bank and on the sidewalk outside. The length of the line made many think that the bank could not possibly pay off everyone. People began to push and then to fight for places near the tellers’ windows. The power of the panic atmosphere was such that two tellers, though they knew that the bank was quite all right and could pay all depositors, drew their own money from the bank. Mrs Vaught says that she had difficulty keeping herself from doing the same.

History is full of examples of leaders joining together to meet common goals. But rarely have two leaders worked together with such friendship and cooperation as American President Franklin Roosevelt and British Prime Minister Winston Churchill. They both were born in wealthy families and were active in politics for many years. Both men loved the sea and the navy，history and nature.

Roosevelt and Churchill first met when they were lower­level officials in World War One. But neither man remembered much about that meeting. However，as they worked together during the Second World War they came to like and trust each other. Roosevelt and Churchill exchanged more than one thousand seven hundred letters and messages during five and a half years. They met many times，at large national gatherings and in private talks. But the closeness of their friendship might be seen best in a story told by one of Roosevelt’s close advisors，Harry Hopkins. Hopkins remembered how Churchill was visiting Roosevelt at the White House one day. Roosevelt went into Churchill’s room in the morning to say hello. But the president was shocked to see Churchill coming from the washing room with no clothes at all. Roosevelt immediately apologized to the British leader for seeing him naked. But Churchill reportedly said: “The Prime Minister of Great Britain has nothing to hide from the president of the United States.” And then both men laughed.

The United States and Great Britain were only two of several nations that joined together in the war to resist Hitler and his Allies. In January,1942，twenty­six of these nations signed an agreement promising to fight for peace，religious freedom，human rights，and justice. The three major Allies，however，were the most important for the war effort: the United States，Britain，and the Soviet Union. Yet，Churchill and Roosevelt disagreed about when  to attack Hitler in western Europe. And Churchill resisted Roosevelt’s suggestions that Britain give up some of its colonies. But in general，the friendship between Roosevelt and Churchill，and between the United States and Britain led the two nations to cooperate closely.
