力的作用作文篇1

大家都知道芦荟这种植物吧。那大家知道它各部分有什么作用吗？让我来介绍吧！

芦荟是百合科多年生常绿肉质草本，它四季常绿。它像开着美丽的绿花儿，其实那不是真正的花，而是叶子。一个个饱饱的好像每天都在不停的吃饭。是的，它每天都在吃饭，但不是米，而是水分和养分。当我轻轻地挤一下，它里面就会流出一些液体，那就是它的血。

听说：芦荟是一种古老的、传统的中药，在我国药典中有所记载，民间普遍用来治多种疾病，其疗效比较显着。老面姓认为芦荟是一种不花钱也能治病的良药，芦荟全草可入药，可清热利湿、健胃。味苦甘，性寒，有消肿拨毒、清热通便、平肝健胃、凉血化淤之效，可治肺结核、烧烫伤、扭伤、消化不良、痈疮肿毒等症，所以人们认为芦荟是家庭常备良药。

芦荟其品种繁多，大约有几百种。但有药用价值的只有十几种，能食用的仅五、六种。药用价值较为突出的是属日本木立芦荟。据日本测定，1克木立芦苇荟生叶含大黄素为0。53毫克，是当今世界所公认最有药效的优良品种。

芦荟中含有多种有效成份，如：各种氨基酸、有机酸、多种生理活性物质、多种微量元素、酵素物质和治愈激素，另外还含有较多的纤维素，对人体的保健、医疗等都有疗效。芦荟中含有芦荟酊、芦荟米酊和芦荟乌辛等，有较强的搞菌作用和破

坏癌细胞的作用。芦荟汁液中含有机锗（羟乙基锗三氧化物），对肺癌、肝癌、白血病等有较好的'疗效，日本制造的芦荟素搞癌剂—a的主要成份就是它。而芦荟甙、芦荟大黄素、异芦荟甙等蒽醌类物质，具有高度的生理性，它直接参与人体的生物化学过程，有利于人体的免疫功能和人体生理活性，并且有润肠通便的特效功能。

看来芦荟全身都是宝，所以我爱芦荟，并且我还栽种了许多芦荟呢！

力的作用作文篇3

高尔基说过：“书籍是人类进步的阶梯。”为了让我这个阶梯越搭越远，越搭越高，妈妈买了许多书让我读。

我推开家门，还未来得及放下书包，妈妈就递过来一大包东西：“喏，你的快递，书到了！”“真的吗？”我扔下书包，抓起一大包书就往房间冲。“哎哎哎！”妈妈叫住了我，“没有剪刀你怎么拆包裹呢？”

我急忙打开书，闻了闻，淡淡的书香扑鼻而来，我不忘告诫妈妈：“千万不要在我读书时叫我哦！”说着，我便“啪”一声关上了门。我看的是《手斧男孩》，主角布莱恩因事故而被迫在丛林里生活。

看的我口干舌燥，于是我起身去倒水，我一边走一边看书，一路跌跌撞撞地来到了厨房，咦，没水了？好吧，我只能自己烧。我接好水，又回到了房间。

当我看见布莱恩遇见熊的时候，我禁不住尖叫了一声，这引得隔间房间的妈妈火速赶来，推开门，问：“怎么了？”我不好意思地笑笑，抓抓头，说：“没事儿，就是看到恐怖部分了！对了，妈妈，帮我倒一碗开水！”我又接着看了起来。

“晨！”妈妈在厨房里叫我，我捧着书走出去，“你看看你！”妈妈对我说，”连烧水的按钮都没按！“呵呵！”我答应一声，可心思全在书里，然后一声不吭地回了房间。

当我把一本书看完时，不由地有些累，我站起身，望了望西边那一角夕阳，呼吸着清新的空气，伸了个懒腰，匆匆结束了今天的“关门读书”的活动……
