    When I was 7 years old,I felt really happy for the first time in my life.I remember that my teacher allowed each student to play various educational games in tum on a computer designed for teaching.One day,I found the source code（编码）for one of these games.Without knowing or being taught any programming language,I was able to figure out some of the BASIG code.I just gave myself an interminate number of lives in the game,so I could continue playing it forever.This was also my first introduction to algebra（代数）,and I didn't even know it at the time.This was a decisive moment in my life.I was quite excited because of what I was learning and what I was able to do.As a result,I was enthusiastic（充满热情的）for the rest of my life about self-learning and computers,and I was quite happy doing them too.

    I've noticed that people who are truly content with life are enthusiastic about what they do.This enthusiasm, along with good health,is the key to being happy.It also leads to self-confidence and content in life too.It may also lead to success,wealth,and achievements.

    Success,wealth,or achievements can also bring some people happiness,yet I know plenty of rich people who are unhappy.I know many people with successful businesses that are not happy with what they are doing.I know people who continuously buy themselves new toys,such as cars,computers,and televisions,yet never seem content for too long.Please remember,happiness is the journey of life,not the destination.

【材料二】民间的声音

关于“闽南话还能存活多久”的讨论帖：

（1楼）：昨天跟5岁的侄子一起吃饭，居然发现这个土生土长的孩子不会讲闽南话。再看看16岁的儿子，也是在泉州土生土长的，比堂弟好点，还会说几句闽南话，但那种老闽南的俚语是一点不懂了。记得我们小时候，连学校老师上课都是方言，如能说一口流利的普通话，那简直就是一门绝活。现在的孩子倒是一口流利的普通话，但会说地道方言的却成了稀罕品种，方言还能在我们的生活中存活多久呢？

（2楼）：我女儿在校讲普通话，在家也讲普通话，现在很多闽南话她连听都听不懂了。

（3楼）：方言还能活多久？那要看我们还能活多久！

（4楼）：不知道，也许有一天，无声无息地消失了。但也没什么可惜的，语言失去交流沟通功能，离消亡也就不远了，这是事物的发展规律。

（5楼）：城市越来越开放，外来人口越来越多，闽南话太土，他们听不懂，还是说普通话好。

（6楼）：“少小离家老大回，乡音无改鬓毛衰。”用方言交流，听着多亲切啊。

（7楼）：方言里有文化，我们老师说闽南话古汉语的活化石呢，我想有文化的东西是不会消亡的。

（8楼）：文物也有文化价值，但是现在不是只能欣赏吗？甲骨文更有文化价值，难道现在还用甲骨文写字吗？

【材料三】学者的声音

“方言里有比普通话丰富得多的生活、情感用语，在动作的细微区分、事物的性状描绘等方面都更具体。这是方言比普通话往往要生动幽默、有趣传神、在文艺表达里更受欢迎的原因。”——钱乃荣（著名语言专家）

“在中国任何一个城市，以普通话沟通不成问题，但你若选择这个城市，却不会讲这里的方言，犹如你爱上一个人，却读不懂他(她)的内心世界，要融入其中，谈何容易！”——程乃珊（著名作家）

“没有方言的城市是可耻的。” ——（《新周刊》执行总编）

“我们的态度是大力推广普通话，同时采取必要的措施积极保护方言。”——陈章太（教育部语言文字应用研究所研究员）（引自互联网）
