Shortly after the war ended, Lincoln was shot while attending a play in a Washington theater. He died within a few hours. The uncontrolled emotional reaction of the nation to his death was almost unbelievable and demonstrated the deep esteem in which he was held. Newspapers were edged with black; religious leaders gave praise of Lincoln instead of their prepared sermons. His funeral procession in Washington was miles long. Lincoln’s body was taken by train back to his former home in Spring Field, Illinois, but in all the major cities through which the train passed, the coffin was paraded through streets lined with sorrowful thousands. In the small towns through which the train passed, bells rang in honor of the dead President. Citizens lit torches along the railroad track to show their last respects.菱形写作法：即主题句出现

When we watch a person walk away from us, his image shrinks in size. But since we know that he is not shrinking, we make an unconscious correcting and “see” him as retaining his true stature.

Good manners are important in all countries, but ways of expressing good manners are different from country to country. Americans eat with knives and forks; Japanese eat with chopsticks.
