细胞基本组成的英语小作文【一】

做读书笔记并非简单的“摘、抄、辑、录”之类的纯技能性工作首先就有一个择取、筛选的问题。这“择取”和“筛选”要经过思考和判断必须在认真阅读之后以对书的内容有清楚的理解为前提。而通过做笔记又能促进对书的内容的更深刻的理解。

评论式笔记不单是摘录,而且要把自己对读物内容的主要观点、材料的看法写出来。其中还可表达出笔记作者的感情。评论式笔记有下列几种:

1.书头批注

书头批注是一种最简易的笔记作法。就是在读书时,把书中重要的地方或自己最深的地方,用笔在字句旁边的空白处打上个符号,或者在空白处加批注。如***在读<伦理学原理>一书时,用朱墨两种色笔在书中作了不少的圈圈点点,遇到他认为观点正确、文字优美的地方,就批上“此论颇精”、“此言甚合

我意",认为不对的地方就画‘‘×”,或批上“不通¨、“荒谬”之类词句。

这种笔记方法只能在自己的书上用,这是应当注意的。

2.评注

评注笔记,是读完读物后对它的得失加以评论,或对疑难之点加以注解。例如顾维桢(捕风提影说思维>中的一段文字:

哥德尔的不完整定理。是数学史里的一个里程碑。原来在严谨的数学堡垒之中,竞有一大漏洞,而且这漏洞是无可填的。本来严谨的数学架构,以少数的公理为基础,以明确的推演为方法,导出七层宝塔似备辉煌威果来,真是美不胜收。而且高妙的数学架构,严谨之外,兼具普及性:貌似不同的事物,透过抽象

表达,往往可以归纳在同一种数学描述范围之内,看来真是放诸四海而皆;隹了。哥德尔却证明,凡是普及性高的正式逻辑系统,其中必有某些命题,是无法以这系统的逻辑去辨别其是非的。这毛病多半出在“只缘身在此山中”。

爱德华在给罗塞讲解人体构成的时候,所列出人体组成如下:水30升,碳20千克,氨4升,石灰1.5千克,磷800克,盐250克,硝石100克,硫磺80克,氟7.5克,铁5克,硅3克,还有其余15种微量元素。我们把爱德华所说的`重量相加,这个人体重大概在55千克左右,按照美国化学及土壤局的数据,我们可以得出一个55千克的人,其体内元素组成如下:氧55*65%=35.75千克,碳55*18%=9.9千克,氢55*10%=5.5千克......

下面通过计算来看一下爱德华的炼成原料中碳氢氧3大元素所*的比例:

水的密度为1kg/L,30L=30kg,其中氧30*16/18=26.7kg,氢30*2/18=3.3kg

氨NH3的沸点为-33.33摄氏度,常温下为气态,密度0.588g/L,其中含氢4*0.588*3/17=0.415g,故可忽略

石灰分为生石灰CaO和熟石灰Ca(OH2,若使用生石灰,则含氧1.5*16/36=0.43kg;若使用熟石灰,则含氧1.5*32/74=0.65kg,含氢1.5*2/74=0.04kg

100g硝石KNO3中含氧100*48/101=47.5g

由于其他物质中不含有3大元素,暂不考虑

综合上面数据得出:一个55kg的人体内共有氧26.7+0.43(生+0.0475=27.1775kg或26.7+0.65(熟+0.0475=27.3975kg;氢3.3kg(生或3.3+0.04(熟=3.34kg;碳20kg。

对比两组数据,我们清晰看到,爱德华明显使用了过高比例的碳,而氧和氢的比例过低,犯下这样的错误能炼成功才怪,失去了身体也只能怪自己计算不精了。依我看来,买个计算器远比千方百计的寻找贤者之石有用的多!

提纲式笔记是用纲要的形式把书或文章的论点或主要论据,提纲挈领地记录下来,或是按原文的章节、段落层次,把主要内容扼要地写出来。提纲式笔记可分为提纲和提要两种:

1.提纲

提纲笔记要忠于原书或原文的框架体例或段落层次,对原书或全文作轮廓式的勾勒。它可以用原文的语句,也可以将自己的语言与之相结合来写。

2.提要

提要与提纲不同。提纲是逐段写出要点;提要是综合全文写出要点。

心得式笔记,是在读书之后写出自己的认识、感想、体会和得到的启发与收获的一种笔记。它有如下几种:

1.札记

札记也即留记,是读书时把摘记的要点和心得结合起来写成的。这种札记的形式是灵活多样的',可长可短。

2.

读后感又称读书心得。读者把自己读书后的体会、感想、收获写出来。读后感重“感",它可以是从书中领悟出来的真切的道理或精湛的思想,可以是受书中内容启发而引起的思考与联想。可以是因读书而激发出来的决心和理想,也可以是因读书而引起的对社会上某些现象的感触和评论。

好的读后感已成为报刊上常见的文章样式。写读后感.要注意以下几点:

首先,应该是从读书(包括报刊中引起的“感",离开了书,就成了别的文体。因此,读后感通常在开篇时即要表明“感"是从读什么书报而来,同时,还要载明材料出处。 其次,最好是一则读后感谈一个问题;如果内容多,感想多.可以写成几则,不要混在一起。读后感一定要中心明确,主旨集中。不管感想多么复杂,联想多么丰富,都围绕读物来引发,防止节外生枝。

最后,一个故事、一句话、一个数据、一段议论等等,不论材料大小都可引发读后感。但是决不能肢解原文,歪曲原意,也不要把自己的感想或增添的材料与作者的原文混杂在一起。概括原文要准确,引用原文要忠实。
