1. Ideal is the beacon light. Without ideal, there is no firm direction, without which, there is no life. 理想是指路明灯。没有理想，就没有坚定的方向；没有方向，就没有生活。
                        〔俄国〕列夫·托尔斯泰：《最后的日记》
    2. If a person lacks a beacon light—ideal, his life will be fuddled. 如果一个人缺少一颗指路明灯——理想，就会醉生梦死。

    3. Life is like travelling, ideal is its route without which, one has to stop. If life has no aim, energy will be exhausted. 生活好比旅行，理想是旅行的路线，失去了路线，只好停止前进了。
                        〔法国〕雨果：《海上劳工》
    4. Ideal, you are lonely but true. 理想，你孤独而真实。
                        〔意大利〕卡度齐：《马志尼》
    5. Hope is motive force. 一种理想就是一种动力！
                        〔法国〕罗曼·罗兰：《约翰·克利斯朵夫》
