For thousands of years, animals have trodden a slow path, their spirits together with the body。 But our human being\\'s transportation is too fast。 The body moves but the soul is left behind。 We try to free ourselves in convenience, but we only imprison the soul。 Since we invented how to count hours, we do everything to short the time, short the deadline。 But the time saved can\\'t be shorten。 Nowadays, we spend lots of time staying in front of a TV just changing the channels, while we have no time to talk with a good friend or play with our family。 We have plenty of time to search old news on the internet, while we hardly think about our life。 In the end, the only thing apparent is our loneliness。
Take your time, please。 Try to follow the natural steps and have your own clock。 Try to share your time with everybody you love, share your mind, your happiness and sadness。 Try to read the world we live in, do not only catch a quick glimpse at the society。

化学的学习已经伴随着我有3年的时间了,不长不短,但也让我感受到了了解事物本质的快感与满足感。不知不觉,我也意识到化学是生活中必不可少的存在。
《我们需要化学》清晰地把这样的想法展现出来,也让我从化学的历史和前人的成果中获得了很多。
拉瓦西质疑前人对于氧气的结论,于是实验、并提出自己的想法。就像苏轼不满郦道元与李渤对石钟山名字由来的解释,便亲自到夜晚泊舟,寻觅正解。我们不能随意主观臆断,而应该学会质疑、不断探索、勇于尝试。
化学可以让我们不再拘泥于四季、气候等,而是合理地利用规则。如化肥、农药的研发与改进等。我们能够不再害怕天灾,不再盲目崇拜神明,而是依靠自己。
化学的学习需要结合生物、农业等不同的领域,共同发展,这样才能使我们获得更好的化学素养,更好德地改善生活水平。
现在的食品、服装、珠宝、化妆品、建筑等无不需要化学、依赖化学,学好化学是我们更好生活的第一步。
交往之中,我们需要信任。《三字经》曰:“人之初,性本善。”俗语又有言:“善良的人总比邪恶的人多。”我们应该信任自己的伙伴,信任他是怀着一颗赤诚之心,信任他是真心想和我们做朋友,信任他不会欺骗自己。我们也该信任自己的老师,信任他是一心为我们好,信任他是真心想帮助我们、教导我们。如果交往之中没有了信任,那么,将不会再有一个人愿意帮助你,愿意去爱你,因为你不信任他,他当然就没有理由信任你。想要交到好的朋友,想要让别人相信你,惟有先去信任别的人。可见,交往之中信任是多么重要。
工作之中,我们需要信任。我们应该信任自己的领导,信任他在分配工作时是公平的,信任他不会交给自己完不成的工程。我们也应该信任自己的工友,信任他能和我们一起,完成庞大的工作,信任他会在我们遇到困境时伸出援手。这样,我们的工作会变得顺利许多。试想,当你与领导、工友之间失去了信任的桥梁,会是什么样?领导给你永远写不完的文件报告,工友也对你不理不睬,相信这份工作是不会长久的,又何谈成功呢?可见,在我们的工作中,信任的作用之大。
生活之中,我们同样需要信任。我们应该信任所有旁的人,即陌生人,信任他们对自己没有恶意,信任他们不会没有缘故的加害于自己。我们应该信任社会、信任国家,信任他们不会让“瘦肉精”等不安全的事件再次发生,信任他们能维护谁会的安定、保卫公民的安全。一旦我们失去了这种信任,就会担心一切,人人自危,不仅会让别人觉得不舒服,自己也必定不会愉快。长此以往,便会成为“杞人二号”了。这样的`生活,是人们想要得到的、充满快乐的生活吗?可见,信任在生活中存在的必要。
为什么信任有如此大的魔力?因为多数人是不会轻易信任别人,才会那么需要信任,以至于将你当作是他们的至亲至爱一般对待,正是因此,你会感到无比的轻松愉快,而他们也会将你引上通往成功的路。
让我们一起,沐浴在信任的光辉之下,享受它给我们的福音吧!
《我们需要化学》系列科普专题片汇聚多位化学权威及中科院院士、研究员,一同为化学正名、为化学发声。这套科普纪录片分别以“化学的起源”、“化学与人类饮食”、“化学与材料科学”、“化学与生命科学”以及“展望未来化学”为题材,深入浅出地为我们呈现化学的本源以及我们生活的化学本质。
作为一名化学工作者、一名化学教师,观看了此纪录片深感提高公民化学科学素养,我们义不容辞、责无旁贷。
首先,在初中义务教育阶段的科学课中可普及本片,是培养学生化学科学品质的先机,学生学习化学的动机、兴趣、情感和意志等对学生的学习水平起着十分重要的作用,对化学科学素养的养成也至关重要。
其次,于基础型课程而言,本片既从学科发展和演变的历史侧面解读了某些我们课本教材中的核心概念—教材上几行简洁的平心静气的文字,在它的背后隐藏了许多鲜为人知的“秘密”,在这之中有科学之间的争执和斗争,有科学家的血汗甚至付出生命的代价,本片动态的引人入胜的呈现方式能让学生更好地感悟科学家勇于探索、创新的科学精神;本片又呈现了某些化学概念、规律的由来和演变,这对一线教师通过一定的教学方法使学生理解概念或规律的本意有助力作用,能使学生清晰地认识学科发展脉络,从而树立化学学科意识。科学史学科的创始人乔治·萨顿认为:“使科学人性化的最好方式,即使不是唯一的方式,就是对科学进行历史考察。”因为“无论科学可能变得多么抽象,它的起源和发展的本质却是人性的”。
总而言之,生活需要化学,化学的创造力几乎覆盖了我们生活的方方面面。我们应该更加重视和发展化学学科,重视化学人才的培养。我们能做的就是提高学生学习化学的兴趣,对化学的重要性给予应有的认同,为提高公民化学科学素养,为吸引更多、更优秀的学生从事化学事业尽己之力!
Time flies like an arrow before we realize it .It is known that nothing is more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by, it will never return. However, it is a pity that some people don't make full use of their time .They spend a lot of time in sleeping, chatting, playing computer games or other unmeaning matters. . They don't realize that wasting time is actually equal to killing themselves. They always regret not having made great achievements. One of the reasons may be they do not make good use of time. Therefore, in order to be successful, they should first get into the habit of being on time. It’s a sign of cherishing time. Don't put off what can be done today until tomorrow. Being lazy will eventually lead to failure. Don't wait, because you don't know how long it will take when you put off your plan.

The more we are aware of the significance of this famous saying, the more benefits we will get in study or job.
Take your time

你们好!
我是一位宁波市小学二年级学生。前几天,我看了有关台湾的电视风观片。台湾真是太美了,那里有美丽的阿里山,明净的日月潭,神奇的蝴蝶谷,闻名世界的故宫博物院。当时我就对爸爸说:“我要到台湾去旅游!”可爸爸说:“到台湾可不是一件容易的事。”“为什么?台湾不也是中国吗?”我奇怪地问。
爸爸摸摸我的.头说:“是啊,台湾也是中国,但由于种种原因,到现在还没有回到祖国的怀抱。虽然,祖国大陆亲人和台湾亲人在离别了四十年以后能相聚了,但我们要到台湾去必须绕道香港,大陆的飞机是不能直接飞到台湾的。你说,这能方便么?”
听了爸爸的话我很伤心。不知台湾小朋友是不是和我一样伤心?为了更加了解台湾,我特地到新华书店购买有关介绍台湾的书。 原来,1949年中华人民共和国成立时,蒋介石带着国民党到了台湾,从那以后,台湾就离开了妈妈的怀抱,这一别就是四、五十年。我还知道现在台湾有些人想把台湾变成独立的国家。我看了这样的报道很气愤。台湾的小朋友,你们能答应吗?你看中国的版图,就像一只公鸡,台湾就像公鸡的脚。公鸡不能少了脚,祖国妈妈不能少了自己的孩子啊。我们都是炎黄子孙,龙的传人,应该在一起。
听说,现在台湾不停地在向美国购买武器,我真的很害怕。如果真的打起来,这不是自己打自己吗?我们小朋友还能在明亮的教室里学习吗?台湾的小朋友,请拿起你的笔,写封信给我,我们共同向台湾的大人们大声喊:我们不要战争,我们要和平!我们愿台湾早日回到祖国的怀抱。祝你们天天快乐!
一位热爱和平的小姑娘
