我们国家地大域广，各地的方言五花八门。比如我们舟山话，外地人听不懂，我有时也不能理解有些舟山老话的意思。而普通话是我国的母语，她把全国各地人们的表达联系在一起，成为彼此的沟通的桥梁。所以我们从小就要学习普通话。要是不会普通话，就会闹出许多笑话。
我的奶奶年纪大了，小时候没学过拼音，没设么文化，也说不好普通话。奶奶和我交流说话时，总是半土半普通话，我经常听不懂，所以我决定把奶奶打造成京土贯通的奇才，可是，刚刚开始，就遇到了绊脚石。
先从数字开始学：“一、二、三、四、五。”我说。奶奶认真的学习：“衣、呢、散、四、我。”奶奶发不好“er”和“wo”音，舟山方言把“二”也读成了“ni”。“wo”也不太好发音，这可把我急坏了，但是我还是耐心地一遍又一遍的教，因为奶奶说得还不标准，但也已经渐渐正确了。
为此，奶奶闹了个笑话。那一天，妈妈不在家，奶奶接到一个电话，对方的外地口音，“儿”很重。奶奶压根听不懂。两个大人在电话里牛头不对马嘴地讲了很久。奶奶还没弄明白对方是谁、找谁、有什么事。奶奶急得直流汗，把我叫过去做翻译，原来是妈妈的大学同学，山东人，要到舟山来旅游，顺便看看老同学。挂断电话后，奶奶笑眯眯的夸奖了我。
这次普通话风云让我懂得了：不学普通话的人会给别人许许多多误会，只有学过普通话的人，才是标准的中国人！

书是人类进步的阶梯，书是黑暗中的一束阳光，舒适滋润枯萎花朵的一汪清泉。
书不仅能提高我们的写作水平，还能熏陶我们的情操，我从小爱看书，从著拼音的童话故事到难懂的文言文，这也是一个转变，读的书越来越多，那眼镜片的度数也越来越大，镜片也随之越来越厚，但是都说读书破万卷，下笔如有神，还真是如此，在读书的日积月累中，我的写作水平也越来越高。
虽然喜欢读书是好的，但是一定要读好书，无论是课本还是课外读物，一定要买，要选自己觉得好的书籍，像四大名著等等都是必看的好书籍，读一本好书就像交了一位益友，出示我们的好朋友，我们通过书本与他创造者的灵魂进行接触，沟通交流。
常言道，书中自有黄金屋，读书读好书，都是非常好的习惯，我们从小就开始接触书本，也从书本里吸取知识获得道理，也从书本上认识这个广大的世界，了解前世今生，我们的生活离不开书籍，我们的学习也离不开书籍，从小学到现在，以至于以后的高中大学，我们都要学习课本里的知识，渐渐满足自己，对文化的追求，都说活到老学到老人的一生都需要学习，无时无刻的学习，每个人都离不开书籍，想多读书增加知识见识，就是人世间每一个人都有的，书的故事。
舒适温暖的春风，冬日的暖阳，黎明前的曙光，细腻的雨丝无时无刻在我们身边读好书好读书读书好让我们一起将读书养成一种习惯，在知识里的海洋，尽情的遨游吧，读书是每一个人一生的习惯，这是我坚信的一句话。

嘴的作用作文篇6
我读书，我快乐有句名言说的好：书是人类进步的阶梯。没有文化知识的人，在生活中是很难有立足之地的。刘向曾说过:“书犹药也，善读之可以医愚。”只有书中的知识才能使人变得聪明，也只有书才能医治好人类的愚昧和无知。在我小的时候就特别喜欢看童话故事：《白雪公主》、《灰姑娘》、《小红帽》、《睡美人》……一些故事都十分爱读。妈妈知道我喜欢读书，就买了一本《格林童话》，这让我看见了，高兴的一蹦三尺高，亲了妈妈一下，就连忙跑带自己的房间里，坐在小床上，聚精会神地看了起来。吃饭了，妈妈大喊:“二子，快过来吃饭!”我正在读书，心里全是那些有趣的故事，根本听不到妈妈在喊我。妈妈见我没来，又喊：“吃饭了，吃饭了。”五分钟过去了，我来是没来，妈妈急了，连忙跑到房里，一看我在看书，哄到：“叫你吃饭，你没听见啊！看书都看呆了，快过来吃饭！”我顽皮的还了妈妈一个鬼脸，说：“谁让你女儿这么爱看书，谁让这书有这么大的吸引力呢。”妈妈无奈地笑了。书是你最忠诚的朋友，用文字与你聊天，书是你最好的老师，用文字时刻教导你，书是你最好的伴侣，在你寂寞孤独的时候，带你在书的海洋中畅游……书开阔了我的视野，陶冶了我的情操，净化了我的心灵。是书滋养了中国，强大了中国，书是人类进步的阶梯！
嘴的作用作文篇7
saving water,do it now!
when i was young, i heard of a wise saying about water.the wise saying is : “if we don’t save water, the last drop of water will be our tear-drop.” i was shocked！and since then, i have known the importance of the water. our life can’t go without water, but the water that is available to drink is getting less and less.the 70 per-cent of our body is water, so water is very important. at the same time, the water pollution is getting serious. so, i think we should unite together and do something about it. we can’t just enjoy the modern life, we also should realize our heavy reponsibility---saving, protecting and recycling water. do it now! if not, we will regret some day. perhaps the last drop of water will really be our tear-drop.
