下文是一篇例文，以《每一次进步都以失去或牺牲为代价》(Every Advance Involves Some Loss or Sacrifice)为题。这篇文章是我的一个学生写的。第一段是总体介绍，第二至第四段是文章的主体部分(从历史、文学和个人经历举例)，最后一段是结尾段。
Most people in America, if not the world, would agree that every advance involves some sacrifice. In fact, a common sports adage proclaims: “No pain, no gain.” In other words, progress is always accompanied by a certain amount of loss. This concept is illustrated throughout history,literature and personal experience.
One compelling illustration that some bad always accompanies some good is demonstrated in the Civil Rights movement. In 1955 Rosa Parks refused to give up her seat on the bus to a white person. Although she was arrested and jailed, her brave efforts inspired the Montgomery Bus Boycott which lasted for over a year. Martin Luther King was inspired by her example and became known as one of the most admired figures of the Civil Rights movement.
He organized hundreds of non-violent protests and gave an unforgettable speech entitled “I have a dream.” Martin Luther King and Rosa Parks helped get the Civil Rights Act of 1964 passed. Unfortunately, this social progress was accompanied by a tragic sacrifice: the assassination of Dr. King by a southern madman.
The theme that every advance involves some loss is also demonstrated in Nathaniel Hawthorne’s novel, The Scarlet Letter. The protagonist, Hester Prynne, is charged with adultery and is forced to wear a scarlet letter “A” embroidered on her dress. Although the Puritan community shuns her for her sins, Hester decides to reform her character by doing selfless charity work. As a result of her philanthropic character, the society changes its view of Hester and eventually thinks of the scarlet “A” on her dress as representing the word, “Able”. Through her hard work and sacrifice, Hester is able to move forward with her life and become a valued member of the community.
