1、写人的， When I sat at the desk， trying to write the essay， I found it hard to set pen to paper. Staring at the topic I deliberately chose for myself "my mother"， I felt the memory of 20 years with my mother suddenly turned into a haze， blurring my eyes to discern the past， with nothing towering， nothing flaring， nothing impressive or special enough as a landmark. The haze gradually cleared away， revealing the image of an amicable woman. I recalled a line from the famous movie "Sleepless in Seattle". The radio column hostess asked Sam， "What's so special about your wife？" He answered， "That's millions of small things." Right，trivial and commonplace， like obscure beans， yet woven into the most spectacular necklace by the power of love. My mother is ordinary， but in my eyes she is special. My mother gave birth to me with exceptionally difficult labor. Father received an emergency notice and was faced with a choice between the adult and the infant. Of course，the adult. So my coming into this world was an unexpected fortune at the price of Mother's painful insistence. Thus my 20 years began like this my mother exerted every effort to give me love， but I returned her with a deep scar that was to stay with her all through my growth. My mother is a senior high school English teacher. Under standably， she wanted her daughter to pick up English early to give her an edge to later study， which I did not understand at the age of eight. I was so obsessed with fun and games that I hated to stay peacefully with all those strange phonetic symbols and odd words. I wondered what pleasure Mother seemed to have found in teaching me A，B， C. Wasn't teaching at school tire some enough for her？ I went on strike， refusing to spell a single word no matter how tender or severe Mother tried to be with me. For the first time in my life， Mother beat me， imprinting on my mind. The physical pain was gone long， long ago. But I have finally come to understand how it pained my mother to beat me for my obstinacy and disobedience， and I ache at her pain. Mother never gave up evoking in me an interest in knowledge. She placed the most emphasis on my education and took the most pleasure in my gradual formation of self-discipline in preparing myself for future development. Thanks to her effort and influence， I have been doing well， not only in English， but also in my positive attitudes and conviction towards life. 啤酒主义者 回答采纳率:49.6% 2008-10-14 22:32 A DreamMary: I’m now in the sea.

科学小论文范文(四)火柴做实验是我最喜欢的娱乐方式，我经常会到书店去看一些关于做实验的书籍，然后回家凭着记忆做实验。这天，我又来到书店，突然发现了一个奇异的实验：火柴跳舞。你会相信吗，一根光秃秃的火柴会在水里跳舞？我可不敢相信。我带着一颗好奇的心回到家里，准备用做实验的方法来解开心中的疑团。回到家，与往常一样，我凭着记忆做起了实验。我先端来一盆清水，又拿来一根火柴和一瓶“万能胶”。我在火柴头上涂了一层厚厚的“万能胶”，然后，小心翼翼地把火柴放入清水中。等了一会儿，没见什么反应。我静下心来，耐心等待。又过了几分钟。“奇迹”果然出现了！只见火柴直立在水中，一摇一摆地跳起舞来了。可是，没过半分钟，火柴又浮在水面上。再过了几分钟，火柴又跳起舞来了。如此循环了七八次，火柴再也不动了。是什么神奇的力量驱使火柴“舞蹈”呢？我脑子里充满了疑惑，怎么琢磨也琢磨不透。最终，还是我那无声的老师—电脑帮了我。原来，当“万能胶、与火柴头上的磷接触后，就会产生一种物质。这种物质越聚越多，会使火柴直立起来。这种物质挥发时，火柴便被带动得“舞蹈”起来。一会儿，火柴头最外面产生出来的物质挥发完了，火柴也就不动了。再这一段时间，产生出来的这种物质又聚集起来，火柴便再一次“跳舞”，直到万能胶和磷的反应结束。此时此刻，我才恍然大悟：啊！火柴棍能跳舞，原来是这么回事啊
