Really into the 18-year-old that day, I packed up to go north and south in the motherland of the river, looking for a long time dream of mind. Now I walk in the 17-year-old at the end of the sky to the 18-year-old waved, cried, and told him, "I come, I come to the hearts of the pigeons flying."

When time went by quietly, diluted Aging; when I was immersed in the vision for the future, no taste in the past; when I was maturing, when children are no longer ignore childish, I know, I already alts.
18 years old, does that mean? We do not know the answer. Which indivials do not only do children forever, nor which person will stand with the family roof. Into life, leaving their parents Harbour, is one of life's journey is not retreat, unpredictable one-way ticket.

I not only know how to smile to others, but also to learn their smile;

Not only to know how sincere applause for others, but to learn to walk the stage and firmly;

Not only to understand the loneliness, to the buddy talk, more time to learn to help others to lend their shoulders;

18 years old to me means to stop something and start others.

I also have to get out before the order code of dress, put down all the Dior and unruly boys,

Because I can no longer stand behind their parents, and let the parents standing behind me.

转眼间十七岁就这样再白驹过隙之间溜走了。我迎着冬日的暖阳大步走向十八岁。 十八岁意味着什么呢？成熟？独立？不 我不要这样认为啊 ！

真正进入十八岁的那一天，我将背起行囊走在祖国的大江南北，寻找心中长久以来的梦想。现在我走在十七岁的末尾向十八岁的天空招手，大声告诉他“我来了，我来放飞心中的白鸽”。

当时间悄悄的流逝，冲淡了岁月的痕迹；当我沉浸于对未来的憧憬，不再品味过去；当我日渐成熟，不再理会孩童时的幼稚，我就知道，我已经是成人了。
十八岁，意味着什么？答案我们不得而知。没有哪一个人永远只做孩子，也没有哪一个人永远站在家庭的屋檐下。踏入人生，离开父母的港湾，生活的旅途是一张没有退路、不可预测的单程车票。在波诡浪谲的大海里航行，悲壮多于温情，险阻多于顺达。没有自立意识，没有自主能力，随波逐流，任其漂泊，最终会被浪涛所淹没。
有一次，子路向孔子讨教，何为“成人”，孔子说：“集知识、无私、勇敢、技艺、礼乐于一身，方可谓成人。”古人尚有如此目标，而我们这些堂堂正正的现代青年，甘于落伍于古人吗？
步入十八岁，就是告别幼稚，走向成熟，做一个真正的人。也许我们可以默默无闻，但不可以碌碌无为；也许我们成不了一个成功者，但要努力成为一个有价值的人。
小孩是任性的，而一个成人，不可能向命运撒娇，只有用坚强武装自己，才可以顶得住所有的生活压力，才可以在拥有傲气之后，拥有更珍贵的傲骨。对于这一点，我深有感触，于是在充满竞争的社会里，我学会了逐步培养独立分析、理解问题的能力，由老师牵着鼻子走的日子已经一去不复返了，取而代之的是怎样利用每一点时间进行刻苦攻读。
但是，光阴似箭，我又不得不承认，在与时间的赛跑中，永远是输家。尽管如此，我还是不断的挑战时间，每时每该都在拼搏，都在奋斗，让自己紧张而充实，不再心存杂念……
走过“抽刀断水水更流”的花季雨季，我不会再冲着窗外秋风中的白杨树长叹一声，更不会因为女孩子意味深长的“回眸一笑”而好几天都没有缓过劲来。什么“无可奈何花落去”，什么“聚散皆是缘”“一见钟情”，通通见鬼去吧！
经过一段“迷茫”的日子，我渐渐地改变了起初自己对人生抱有挠幸，存有幻想的看法，牢骚是无用的，真正有理想的人是“志存高远”的。
潮涨还会潮落，花开亦要花谢，但我要说，在某种意义上，十八岁的潮一涨就不再退落，十八岁的花一开就不再凋零，它以前所未有的速度向更高层次的科学殿堂进军而从不曾停留，哪怕困难重重，十年、二十年……
高山上的枯树向天空伸出渴望阳光的手，平静的山谷中绽放一朵朵美丽的花，我不断告诫自己：十八岁，是该告别平庸，负起责任的时候了。于是，我学会了走脚下的路，唱心底的歌，不再回避今天的真实与琐碎，学会承担与征服……
如果说从前是一段无忧无虑的人生初始岁月，包含着一份对父母的深刻依赖，那么十八岁以后则是一份对世界的悄然觉悟，意识到“天将降大任天斯人”的重大责任，并理解“纸上得来终觉浅”的深沉含义及“绝知此事要躬行”的重要性；不再一味地去啃书本，而是理论联系实际，调动积极性；不再是“君子动口不动手”，而是“君子动口更动手”；也不再是高枕无忧，得过且过，而是心系天下，志在四方。
“夜深了，我该给家里打个电话。”这是台湾一句耳熟能详的青年广告语。有一天，我突然发现，心里有了牵挂时，这便说明我们有了负担与责任感。
然而，在“为赋新词强说愁”的十八岁，有些人却故作深沉，整日一副尝尽人生百味、看破滚滚红尘的遁世态度，自以为对一切都满不在乎就是成熟真的是大错特错。
诗人席慕容说“十六岁的花只开一季”。我要告诉所有十八岁的同龄人，我要告诉他们“珍惜吧，咱们十八岁的花只开一季！”
哦，十八岁，人生独一无二的十八岁，我们该如何面对呢？
……
孤寂的学海之旅在十八岁以后将更是难上加难，为学业所累为人情所伤为世俗所扰是在所难免的，成长的一切烦恼都要我们自己来解决。在种种挫折、苦闷、彷徨中，我们才可以逐渐坦然面对。读书苦，黄卷青灯，披星戴月。却不是件该怨恨的事，不该叫苦喊累，怨天尤人。毕竟是成人了，很多事情都不能再像以前那样幼稚，想放弃就放弃，得学会对自己说“不”，学会三思而后行……
带着无限企盼和憧憬走过伤痕的沼泽，越过幼稚的山峰，我的心填满了殷实的希望，饱满的信念。我洒脱地对自己说：“至少我的未来不是梦”。这是成熟的启迪还是自我超越呢？
站在阳光中，我看到自己渐渐成长，飘洒在阳光中的头发泛着青春的光泽。拥有一分久违的潇洒！
18岁对我来说意味着长大，意味着我再也没有借口自私地活着。

要收住愤怒的拳头，把冲动扼杀在心间；

要学会安慰发牢骚的妈妈，劝诫晚回家的爸爸；

18岁对我来说意味着完成了人生当中一次重要的自我认同。

我不仅要懂得对别人微笑，更要学会对自己微笑；

不仅要懂得真诚地为他人鼓掌，更要学会坚定地走到台前；

不仅要懂得在孤独时向哥们倾诉，更要学会在他人无助时借出自己的肩膀；

18岁对我来说意味着要停下一些事，而开始另一些。

我再不能撒野似的耍到夜深，小猪似的睡到正午；

因为18岁的男孩啊，就像那一晃而过的春天，最浪费不起的就是时间.

再不能孤傲的挥袖而去，潇洒的随风飘来；

因为18岁的男孩啊，就像那已经长开的小树，往那儿一立，就是一个坑；伸伸手臂，也有一片荫；在别人眼中啊，他的一举一动都有了份量。

但是

我必须走出家门，能走多远走多远，不管有多么的困难多么的不舍；

因为鸟儿一定要在试飞的年龄，舒展双翅，感受逆风的威力，否则就永远学不会飞翔。

我还必须在走出家门前整理衣冠，放下男孩子的一切桀傲与不羁，

因为我再不能站在父母的背后，而要让父母站在我的背后。

9. 为什么要学习化学这个专业400字,英语作文

我们周围有形形色色、 丰富多彩的各种物质， 像清新的空气、 潺潺的流水、 晶莹的金刚石、 乌黑的煤炭、 洁白的食盐、 闪光的金属、 绚丽的塑料等等。 还有食物中所含的淀粉、 脂肪和蛋白质， 做衣服用的棉花和化学纤维，造房子用的水泥、 黄沙和石子， 制造火车、 汽车用的钢铁和橡胶等都是物质。世界上的物质都在不断地变化着。 大海中的水可以变成天空中的白云，飘浮的白云又可以变成雨、 雪降临大地。 铁矿石能冶炼成坚韧的钢铁， 钢铁也可能变成无用的铁锈。 蜡烛能着火燃烧， 发出光和热后化作气体散逸到空中。
在日常生活中， 你的脑海里一定会有各种各样的问题。 例如， 空气、 水、钢铁、 煤炭、 塑料、 水泥等物质由什么组成的？ 为什么世界上有那么多种不同的物质（据统计约有 1000万种） ？ 为什么各种物质的性质（颜色、 状态、气味、 密度、 硬度等） 多种多样、 各不相同？ 为什么各种物质会发生不同的变化（煤炭为什么会燃烧？ 水为什么可以灭火？ 铁为什么会生锈） ？ 为什么，为什么……
要能回答以上这些问题， 我们必须学习一门基础自然科学——化学。
我们说，世界是物质的，物质就是组成物体的材料。物质的变化是多种多样的。 在小学自然课里曾讲过水有三种状态。 水冷到 0℃时会结成冰， 水蒸发会变成水蒸气。 液态的水、 固态的冰和气态的水蒸气都是同一种物质， 只是状态发生了变化。 固态铁受热到 153 5℃熔化成液态的铁， 钢铁厂内炼铁炉里火红的“铁水” 就是液态的铁。 液态的铁继续受热到 27 50℃时还会沸腾， 变成气态的铁。 外观不一样的固态铁、 液态铁或气态铁却是同一种物质。 我们日常看到的木材做成桌椅、 钢轧成钢轨、 灯泡通电发光、 音叉敲击后发出声音等变化， 都只是物质的状态、 形状等发生了变化， 并没有生成其他物质。 我们把这种没有生成其他物质的变化叫做物理变化。
下面我们通过实验来研究物质的另一类变化。 注意观察变化前后物质的颜色、 状态等， 以及变化时发生的现象。
【 实验一】 在一个盛有少量澄清石灰水（含氢氧化钙） 的试管里， 插入一根玻璃管， 通过玻璃管吹气。我们发现，通入二氧化碳后， 石灰水变浑浊， 生成白色沉淀，这白色沉淀是碳酸钙。
Ca(OH)2+CO2=CaCO3↓+H2O
【 实验二】 取一小段用砂纸擦亮的有银白色光泽的镁带， 用坩埚钳夹住， 放在酒精灯的火焰上点燃。我们发现，点燃后， 镁带燃烧， 发出耀眼的白光， 同时放出大量热，留下白色粉末——氧化镁。
2Mg+O2=点燃=2MgO
【实验三】 取少量绿色的碱式碳酸铜粉末（这是一种碱式盐），放在干燥的试管里，用配有玻璃导管的橡皮塞塞住管口， 使导管的另一端伸入盛有澄清石灰水的烧杯里，加热。我们发现，加热后，变成黑色的氧化铜粉末， 管壁出现水滴，生成的无色气体能使澄清的石灰水变浑浊。
Cu2(OH)2CO3=Δ=2CuO+H2O+CO2↑
我们日常看到的木柴燃烧、 铁的生锈、 食物的腐败等都是化学变化。物质在发生化学变化时， 常伴随发生一些现象， 如放热、 发光、 变色、生成气体或沉淀等等。根据这些现象， 有助于我们判断物质是否发生了化学变化。
点燃蜡烛时， 石蜡受热熔化是物理变化； 而石蜡燃烧生成二氧化碳和水，是化学变化。 在化学变化的过程中一定同时发生物理变化， 但在物理变化的过程中不一定发生化学变化。
物质不需要发生化学变化就能表现出来的性质， 如颜色、 状态、 气味、 熔点、 沸点、 硬度、 密度和溶解性等等， 叫做物理性质。 物质在化学变化中 表现出 来的性质叫 做化学性质。 例如， 镁能在空气中燃烧， 生成氧化镁； 二氧化碳能使澄清石灰水变浑浊， 生成碳酸钙沉淀；碱式碳酸铜加热后会变成黑色的氧化铜和水，并生成二氧化碳气体。铁在潮湿的空气中能生锈等。
要研究千变万化的物质世界， 解释物质变化中无数的为什么， 就必须学习化学。化学是一门研究物质的组成、 结构、 性质以及变化规律的基础自然科学。
我们学习化学， 认识化学变化的原理， 掌握化学变化的规律， 不仅可以说明生活和生产中的一些化学现象， 还可以控制某些变化向着对人类有利的方向发展。 例如， 懂得了燃烧的原理， 就可以创造条件使燃料燃烧充分， 提高燃料的利用率， 还可以知道怎样防火、 灭火等。 又如， 知道了引起环境污染的有害物质， 就可以设法消除污染环境的因素。人们运用化学变化的原理， 可以从自然界中提炼、 制造出各种有用的物质， 例如， 从矿石中提炼出金属。 还可以用石油、 煤、 水等制造出自然界原来并不存在的塑料、 合成纤维、 合成橡胶、 洗涤剂、 染料、 药品等物质。
学习化学， 可以帮助人们研制具有各种特异性能的新材料、 研究开发新的能源、 探索生命现象的奥秘、 合理利用自然资源、 保护生态环境、 促进农业发展和进一步研究物理学、 生物学、 地学、 天文学等自然科学。
可见， 化学跟现代社会生活和我国四个现代化建设都有密切关系， 学习化学对我们今后参加社会主义建设和进一步学习都有重要作用。我国是世界上文明发达最早的国家之一， 有着光辉灿烂的古代文化。 我国古代的化学工艺和化学知识是祖国文化宝库中的珍贵遗产， 也是世界文明史中的重要篇章。
我国是世界上最早发明造纸、 制火药、 烧瓷器、 冶炼黄铜和白铜等化学工艺的国家。 战国时代开始兴起的炼丹术是古代化学的起源。我国劳动人民在商代就制造出精美无比的青铜器， 春秋晚期就会冶铁， 战国晚期就会炼钢， 在世界上最早发现并利用石油、 煤和天然气。
但是，到了近代，我国科学技术的发展停滞了。 在解放前， 甚至连烧碱（氢氧化钠的俗称）、 煤油等都要依赖国外进口，那时，人们把火柴叫做洋火，煤油叫做洋油，钉子叫做洋钉，蜡烛叫做洋蜡烛。
解放后， 我国的化学工业、 石油工业等都有了很大发展， 化学科学研究也不断取得了新的成就。 我国化学工业已发展成为一个具有一定规模、 行业基本齐全的工业部门。
1965年我国科学工作者在世界上用化学方法第一次人工合成有生物活性的蛋白质， 对探索生命奥秘作出重大贡献。 我国原子能的利用、 航天技术的卓越成就集中标志着我国科学技术， 包括化学科学， 已达到世界先进水平。建设社会主义的现代化强国需要化学。 例如， 现代农业需要大量化学肥料、 高效低毒的农药和塑料薄膜等； 现代工业需要耐高温、 耐腐蚀、 不易燃烧的高分子材料， 高强度的合金等； 现代科学技术上特殊需要的各种化工产品， 像原子能反应堆用的核燃料， 火箭、 飞机所用的轻质合金、 推进剂， 电子工业用的高纯物质等。 制造这些材料和产品都需要用到化学知识。
首先， 要明确学化学的目的。 今天我们在学校里辛勤地学习， 明天我们将献身于社会主义祖国的四化大业。要学好化学， 不仅要遵循一般的学习规律， 还要针对化学的特点学习。
化学实验对化学科学的发展起着重要的作用。 学习化学一定要认真做好化学实验。 在化学实验中， 要正确地进行操作， 细致耐心地进行观察， 详细、 准确、 如实地做好记录， 并根据实验得出结论， 寻找规律。
学习化学一定要理解基本化学概念和规律， 熟悉重要物质的组成和性质。 对表示物质的组成和变化的化学符号要明确含义， 经常练习， 做到会读、 会写、 会用。
学习化学要理论联系实际， 了解化学知识和技术在工农业中的应用， 并能运用所学知识去解释生活中的简单的化学现象。 要使学习取得成效， 应该注意培养和保持对学习化学的兴趣， 在学习基础知识和基本技能的过程中， 逐步提高自己的观察能力、 思维能力、 实验能力和自学能力。
希望同学们勇敢地跨入化学科学的殿堂， 不辞辛劳， 勤奋进取， 去挖掘科学的宝藏。 时刻准备着， 用火红的青春为社会主义祖国四个现代化的宏伟大厦添砖加瓦。
希望我能帮助你解疑释惑。
