21:03 の マ 自46% 294 長い文章 16 What does the speaker say about Abraham Lincoln's speech? 0 It was considered a complete failure. 2 It was given at a cemetery for soldiers. 3 It was nearly two hours long. の It was given a score of four out of seven. Sp The Gettysburg Address The Gettysburg Address is one of the most famous speeches in U.S. history, but when Abraham Lincoln finished delivering the speech, he thought it had been a complete failure. The speech was not even the main speech given that dov.a dedication of a cemetery for the thousands of soldiers who had died in the Battle of Gettysburg a few months earlier. After the main speaker had spoken for nearly . hours, the President spoke for only a few minutes. His speech was only ten senten.. long, but it reminded Americans why they had fought to create a new country and urged them to fight on to save it and make it greater. The reason Abraham Lincoln's speeches are so memorable is that he wrote and rewrote them until they sounded almost like poetry. For example, he ends the speeck with, “that government of the people, by the people, for+he people, shall not perish from the earth." By repeating, "of the people, by the people, for the people," he makes the phrase easy to remember. But, of course, it is the opening of the speech that even school children can recite: “Four score and seven years ago." A“score" is twenty years, so he is really saying, “Eighty-seven years ago.” But “eighty-seven years ago" doesn't sound very poetic, does it?

Although one of the principles of fair play is to fight hard, you can sometimes win by avoiding the fight. Do you know a strategy called an intentional walk in baseball? Pitchers throw four balls on purpose and let the batter take first base. In this way, they take away s the chance of strong batters hitting and scoring points. In time-limited sports such as soccer and basketball, wasting time is another strategy to win by avoiding a fight. The winning team goes on passing toward the end of the game. In this way, the losing opponent has no chance to get the ball and score. COnar Some people think that you should do whatever you can do to win as long as you do not break the rules. Others, however, feel that avoiding a fight is not fair play at all.
