everyone has the first time experience. as i remember the most rememberable experience i have came through was the first time i learn how to ride the bicyble by myself when i was still a ignorant and young little boy. it certainly was a difficult challenge for a seven years old boy who's feeble and vulnerable but nothing could tribulate a kid who with a struggling determination that had frequently accomplished incalculable conflict by himself. undoubtedly the experience of learning how to ride the bicyble had a incredible impact on my life that i authentically have acquired a value statement in my mind "don't ever lose hope and give up before things turning fine" which motivated me to overcome this challenge successfully.

i remember vividly the day i learned how to ride a bike. it was a sunny summer morning perfect for being outdoors. ............每个人都有第一次体验。我记得，我有最刻骨铭心的体验经历是我第一次学会骑bicyble我当我还是一个懵懂的年轻的小男孩。这当然是一七岁男孩的软弱和脆弱的一个艰难的挑战，但是没有什么能tribulate孩子与奋斗的决心，经常完成自己不可估量的冲突。毫无疑问，经验学习如何骑bicyble对我的生活产生了不可思议的影响，我确实已经在我的心里获得的值的声明，永远不要失去希望，放弃之前的事情变好，这鼓励我克服这一挑战成功。

我清楚地记得我学会骑自行车的那一天。这是一个阳光明媚的夏日早晨，适合户外。............

“啊！放假了，终于可以不用读书了！”

“哎！奶奶，我想读书，我想同学了！”

放假没几天，我的态度就发生了360度大转变，我也捉摸不透。我们正常上学时，总惦记着什么时候过节日，可以放假；可一但放长一点的假期，我们都会彼此想念，想要回校读书。

好比我们去旅行：刚出发的时候真兴奋！天天四处玩，吃餐馆，住酒店，唯恐这么几天玩不够。可慢慢地，时候久了，你就会慢慢得想家了；当家门近了，又会说：“回家真好。”

人的生活都生活在这种矛盾中；人的可爱，也就在这“一动”与“一静”之间的矛盾：心理学家曾做过这样一个实验——他们把盐、糖、面、各种好吃的不好吃的东西，都放在娃娃前。娃娃们每一种都抓近嘴里，都尝尝。有些东西，譬如盐，他们放进嘴里就吐，甚至气得哭。但经过长期观察，虽然那些东西娃娃不爱吃，但如果是身体需要的，他们都会忍着苦，忍着咸往嘴里送。

读书也是一样是人的本能：我们可能因为考试太多、功课大多，压力太大而不想上学。但是真的给了你自由，后来你却可能自己去求学。就如古代的许多小牧童、小乞丐，躲在私塾门外偷听，没人逼他们念书，他们应该正高兴啊！为什么反而要偷偷学呢？

这恰恰说明，某些东西是我们是省不了的，也警示我们，应该把握青春年华，珍惜时间，好好学习。莫要“黑发不知勤学早，白首方悔读书迟”啊！

water is very important to us. if you don’t have water for three days, you will die. we can use water for flowers, swimming, washing many different things. we use it to cook, make electricity, put out fires and so on. we use millions of liters of water every day.

do you know how does the water come to your home? it travels through water pipes. some are long and wide but some are short and narrow. then the water travels through the water pipes to the reservoirs. then it travels through the water pipes to the river and to the special factories (we call water plants) that purify the water. when the water is purified, we can drink it. please don’t leave garbage in the water on which we live, and keep the water clean.

同学们，你们喜欢读书吗？你们都爱读什么样的书，是那种读起来让你眉飞色舞、拍案称快的，还是那种让你浮想联翩、遨游太空的？是专业的还是休闲娱乐的？无论怎样，请你拿起对我们人生有益的书，走入书的海洋，因为在那书海里，你会开阔视野、充实思想、丰富情感、改变人生，更能让作为学生的我们寻找到一份不同以往的自信和理想。

记得高尔基曾说过：“书是人类进步的阶梯。”通过读书，我不仅吸收到了知识，学会了许多做人的道理，感觉到了读书的乐趣。看了《白雪公主》，我为她的机灵而欢呼；看了《钢铁是怎样炼成的》我为剥削社会的黑暗而叹息……

高尔基还说过：“书籍使我变成了一个幸福的人。”我们又何尝不是呢？读书带给我们最隽永的乐趣，最恒久的动力；读书带给我们心灵的和平，精神的慰籍。朋友可能离去，书却是最忠诚的伙伴，时光不断流逝，阅读却让我们永葆青春！不仅如此，读书使我们逐步建立起和古今中外伟大作家之间的交流，依他们的指引，历史的大门为我们打开，未来为我们展现理想的蓝图。

记得莎士比亚曾经说过：“生活里没有书籍，就好像没有阳光，智慧里没有书籍，就好像鸟儿没有翅膀。”当我们烦恼时，书会带给我们快乐；当我们无助时，书会带给我们知识和力量；当我们毫无目标地徘徊时，书会带给我们理想的目标。同学们，热爱书吧，因为书是我们永远的朋友！读书，真好！

谢谢大家，我的演讲完毕！

每听到同学们都抱怨读书的缺点呀、坏处呀，我却都好奇的挠挠头，不知读书有什么坏处。据我所知，读书的好处可是数不胜数呢！

读书，赢得夸奖

一次，在一节课文课上，老师在黑板上写了一个成语，其中有一个字同学们都不知道，纷纷猜测，教室里立刻乱成了一锅粥，说什么的都有，同桌问我：“你知道这字怎么念吗？”我摇摇头又点点头，小声说：“好像是念shǔ吧！”记得上次爸爸让我背三字经时，有一句是“稻粮菽，麦黍稷，此六谷，人所食。”其中的shǔ和老师写得那个字一模一样，我便大声的说：“老师，那个字念shǔ。”老师查了字典后认定是念shǔ。下课了，同学们纷纷问我是怎么认识这个字的，我告诉他们后，他们纷纷夸我见识多，我笑在脸上，乐在心里。

读书，增长知识

一个星期天，我和表妹曼曼一起玩。突然，天上打起了雷，表妹吓得一下子躲到屋子里大叫：“姐姐！姐姐！天上打雷啦！”边喊边用手捂住耳朵，可雷声却仍然回荡在耳边，表妹吓得手舞足蹈，不知所措。我拍拍表妹的肩，说：“别怕，不用用手盖住耳朵，你张大嘴巴试试，我在《十万个为什么》上看的，你试试！”表妹听了，不捂耳朵了，张大嘴巴，果真，雷声不太响了，我又跟她说说话，雷声根本就没有了。

读书，过得充实

以前，一二年级，我不太爱读书，写完作业就知道玩。直到三年级时，我接受了爸爸送我的第一本绘本加故事的书——《读友》，当我翻开第一页时，就被它吸引了。从此，发展到我写完作业再把作业给妈妈检查时看书，有空时看书。星期六星期天也看书，发现了许多神奇而奥妙的事。

读书，使我终身受益！读书真好！

is science dangerous

the rapid development of science and technology has brought about great changes to human life, including great harms and disasters .then people enter into endless argument about whether science is dangerous or not.

so many examples can be figured out to prove the danger of science. advanced technology can be easily manipulated by irresponsible persons as well as terrorist. such as the disaster 911, airplanes fly into buildings, fire burning, huge structures collapse, a lot of victims such as intellectual and business elites were sacrificed. besides, as technology becomes more powerful day by day , well be complacent and lazy. increased dependency on modern tools like calculators has reduced on our creativity. students can’t solve a very simple mathematical equation without using a calculator. this affects the way these students uses their brains and reduces on the level of creativity.

just like the saying goes that every coin has two sides. however, it ‘s obvious that we make the decision to choose which side. after 911, people condemn the terrorist not airplays. student who got low marks should rethink his carelessness and laziness but not pass the buck to the calculator.

any way, there is no dangerous science, but dangerous and irresponsible people. we are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful. actually, the key lies in the user. moralities such as responsibility, diligence and goodness should never be lost in our heart. otherwise , the world would be full of danger even we turn back to the stone age.
