description列表不得不说的用法
LaTeX技巧303：description列表不得不说的用法常见数学排版问题集下载在我个人使用经验里，Description 用的不很多，作为LaTeX列表的一个典型。
我研读了一下，也发现如下几个问题，希望对您的使用有所帮助。
基本用法首先看一个Description的示例。
\begin{description}\item[First Item] This is a shorter item label, and some text that talks about it.The text is wrapped into a paragraph, with successive lines indented.This is another paragraph under the item.\begin{description}\item[Sub-Item] This is a description of an item which is within thefirst item.\item[Sub-Item] Another sub-item.\end{description}\item[Second Item] Another item that's not part of above item.\end{description}description顾名思义，对列表项的解释描述等，description项描述可以是多个段落，也可多个环境嵌套。
显示结果为：有时，这样使用description觉得不是很符合我们的使用习惯。
第一，让label 项换行显示如何设置？解决方法：\begin{description}\item[{\parbox[t]{3cm}{first line\\second line}}] This is a shorter item label, and some text that talks about it.The text is wrapped into a paragraph, with successive lines indented.\end{description}但是这会影响，后面文字的格式，目前我没找到更好的解决方案，欢迎您提供。

General and Specific Words for Good Description
❖ Specific words help to make writing clear, exact, vivid, and striking, for they are more informative and expressive than general words. Compare:
❖ Using spatial order: describing the physical layout of the place(left>right, bottom> top, clockwise/counterclockwise, inside>outside)
❖ Using chronological order ❖ Use specific words ❖ Decide on the dominant impression
Note: Few descriptions outside of science writing, however, are completely objective.

❖ Vancouver’s summer sunshine makes me lazy. I indulge myself under the shade of the maple trees during the summer in Central Park in order to bask in Vancouver’s sunshine. Especially when the wind waves the leaves and the sunlight slides through, it feels like velvet patting my body or like a furry cat rubbing me. I like to sit on the bench, which is on the southern shore of the lake. One day, an old Labrador dog sat beside me. Although there were many adults jogging, children giggling, and squirrels chasing around, the old Labrador was as solid as a rock; he closed his eyes and ears and made his daydream without a pause.

4.3 Use Specific and Vivid Language
One of the basic rules of composition is to be as specific as possible-if we want to impress the reader. Apparently, the more specific the words and expressions we use, the clearer the picture will be. Specifically, we should try to enable the reader to see, hear, feel, smell, or taste what is being described and to use specific and vivid expressions that appeal to the sense and provoke the reader’s imagination.
4.4 Emphasize the Theme in the Conclusion
The conclusion should not be a simple repetition of what is said earlier because that would not be able to strengthen the impression of the composition on the reader. A good writer usually ends a description by emphasizing the theme again with a new turn of thought. The following are different endings for a description of an 8:00 a.m. class:
title、keywords、description的写法及需注意的重点
title、keywords、description的写法及需注意的重点时至今日，还有很多人在纠结着到底网站的title、keywords、description要不要按照一定的标准去书写，因为这个标准的确没有官方的认可。
而现在很多人滥用之就常常导致被搜索引擎认为是在堆砌关键词进而最后发展为作弊。
所以，现在搜索引擎已经不怎么看重这三项内容了，但是从一些优秀的网站上还是可以看出这些东西的书写规则还是比较标准的，所以大家临摹一下也未尝不可不过要想了解这三个元素的一般书写规则的话，就首先应该知道他们三个东东到底是什么。
下面的解释仅供新手SEO入门学习，高手请绕道。
title、keywords、description是什么？title：即网站标题，也就是在浏览器上面显示的那些内容，这些内容不仅用户能看到，而对于搜索引擎来说也是能够检索的到的，而且要特别注意它还是判定你网页的主要依据之一。
Keywords：这也就是我们常说的关键词了。
Kewords用户是不能直接在网页前台看得到的。
只有查看网页源代码才行。
Keyword的主要作用是把当前网页的内容用几个简明扼要的词语来概述一下。
这里还牵扯到一个关键词密度问题，以后再细谈这个keywors密度。
description：这个和上面的keywords一样，同样是用户直接在当前网页上看不到的内容，而且也是对于一个网页的简要内容概况。
但是又和keywords不同，keywords是几个词语的组成的，而description 则是完整的一句话，就像本博客的首页描述一样。
title、keywords、description的一般写法Title的一般写法：首页title的写法，一般是“网站名称–主做的几个词语或简单描述”。
在这里讲一下个人感觉，本人在做优化有时候习惯把相对较难的几个关键词放在标题最前面，网站名称放在后面，因为搜索引擎给予标题最前面的词肯定要比后面的高的。
就譬如说我这个博客做“郑州SEO”这个词，就这样写“郑州SEO_武汉网站优化_SEO基础教程学习，而反观很多小网站都是这样去书写的，但是也不唯一。
title、keywords、description的写法
title，也就是标题，一般方便用户了解这个页面的内容，这里就是判定你网页内容的主要根据。
1.首页title写法：首页的title写法格式一般是“总标题-关键词”。
2.栏目页title写法：栏目页title的写法有两种，关键词名称命名写法是“栏目名称-总名称”，非关键词命名写法是：“栏目名称栏目关键词-总名称”。
3.分类列表页的title写法：用关键词为这个栏目起名，然后按照下列顺序填写便可了“分类列表页名称-栏目名称-总名称”。
在标题中，即使主、辅关键字及词频都相同，表达方式也各有不同。
以下是两种最常见的标题表达方式：方式1：<title>小游戏| 休闲小游戏</title>方式2：<title>小游戏- 打造全国最好休闲小游戏网站</title>这两种表达方式除了能有效提高主关键字”小游戏”的词频外，还增加了意义相近的辅关键字”休闲小游戏”。
其中，”A”中采取的是多个关键字简单排列的形式；而”B”则采取的是对主关键字进行描述的形式，这样不但更能得到搜索引擎的青睐，同时也更能吸引用户的点击。
Keywords就是一个网站给首页设定的以便用户通过搜索引擎能搜到本网站的词汇，网站关键词代表了网站的市场定位。
网站的关键词至关重要，如果选择的关键词不当，对网站来说就是灾难性的后果。
标准网站keywords写法keywords，我们称他为关键词，keywords不察看源程序是看不到的。
主要作用是简单内容的关键词简述。
1.首页keywords写法首页keywords按照选定的栏目名称，在首页的keywords中加入总名称、栏目名称和一两个关键词。
2.栏目keywords写法栏目的keywords其栏目下所有分类列表的名称列出，加上栏目关键字，写法是“栏目名称,栏目关键字,栏目分类列表名称”。
3.分类列表页keywords写法将你这个栏目中的主要关键字写入Description在SEO的重要性descriptionb音变为p,desctip + -tion名词后缀在现在网站建设中，Description是出现在页面头部的Meta 标签中，用于记录本页面的概要与描述！Description作用：Description出现在网页的<head></head>之间meta标签之一，可称为“内容标签”，“描述标签”或“内容摘要”可以预见在以后的用户搜索中Description会扮演越来越重要的技术之一。
Narration (叙述文) vs Description (描述文)
例如：過去：I lived inEnglandtwo years ago.
現在：Nowadays I live inHong Kong.
未來：I shall live inAmericanext year.
(a) Marywalkeddowntownyesterday.
(b) Isleptfor eight hours last night.
簡單過去式用以描述活動或狀態在過去時間內開始並結束。(如昨天、昨晚、兩天前、1999年時)
(c) Bobstayedhome yesterday morning.
(d) Our planearrivedon time last night.
大多數簡單過去式的形式是在字尾加-ed，
如例(a)、(b)、(c)、(d)。
Narration (敘述文) vs Description (描述文)
發展技巧：
(1)敘述文：採「第一人稱」觀點,作者本身融入其中一角色。
(2)描述文：採「第三人稱」觀點,作者為圖中主角命名，以第三表示某動作或狀態是在過去、現在還是未來發生，除了可用動詞以外的其他詞表示外，動詞本身亦要用不同的形態來表示。
(e) Iatebreakfast this morning.
(f) Suetooka taxi to the airport yesterday.
有些動詞的過去式為不規則變化，如例(b)、(e)、(f)。
(g) Iwasbusy yesterday.
(h) Theywereat home last night.
Be動詞的簡單過去式式was與were。

description描述要点
我们都知道description是网站描述，描述我们需要注意那几个要点：第一个要点，字数的限制，描述，官方定义字数是75个字，这样的限制是对网站有益的一个机制标准，为什么是限制75个字呢？搜索引擎对我们网站描述的扫描就是75个字，因为描述超过75个字，用户也看不到，搜索引擎扫描最多也就是三行。
但真正的不到3行。
第二个要点，分隔符的采用，我们一般的分隔符是逗号, 正常标准采用是逗号，逗号有全角和半角，我们同场建议采用半角，逗号是便于用户阅读和表达的描述方式，所以逗号是符合搜索引擎对网站的友好的方式。
如果我们采用全角的话在位置上，全角是要大于半角的。
我们利用半角的话，我们可以放入更多一点的文字，另外文字的描述要精简和易于被读懂。
第三个要点，关键词的问题，第一我们要求关键词的位置尽量靠前，我们建议把主要的关键词靠前放，关键词在网站的标题里越是考前那么这个关键词是越重要的，那么关键词的排序和位置是很重要的，比如首页内做3个关键词，我们应该把热门竞争关键词的排序。
重要的关键词是从左到右，同时给用户提供可阅读性。
第四个要点，描述除了放置关键词，还要具有可阅读性，我们不建议标题和描述不能完全一样，这样的描述完全没有可阅读性，如果你网站的关键词和描述重复那么搜索引擎认为你网站是不合理的，时间长了会认为你网站是优化过度的，我们在优化每一个细节的时候Keywords 和 Description 不要重复，网站的描述一定要具有可阅读性，并且形成一句话，并且要概括我们网站的内容，第五个要点，description 描述里面的关键词布置，这个描述里面要含有在我们标题里面放置不下的关键词，我们在title里面如果放置不了那么多的关键词，那么我们可以把剩余的关键词布置在我们的描述里面，那么我们发现把剩余的关键词放在描述里面是对于关键词的排名是非常有利的。
第六个要点，description的用户体验，我们在描述里面一定要记住几个重点:1 描述里面要含有优惠或者专业，或者产品质量的优势或者（活动）等等，那么我们研究发现是因为描述和标题做的有吸引力，利用描述和标题来吸引用户对我们网站的点击。

The monotonous（单调 的） color sketches out (勾 勒出)the picture, and it shows us that a tired mother takes her children to go to the market. Thought she has a poor family and works busily ,she still stops her works to take her children out because she could not bear to reject the desire of the child’s eyes.
The little girl who is in mom’s arms can’t be more than three. She is a little plump（圆胖 的）,but she really takes after her mother. She has got her mother’s mouth and the most beautiful almond-shaped（杏 仁状的）eyes. I can’t really move my eyes from her left hand. She clenched tightly a thing hung on her neck for fear that others will take it away. It may be is a crucifix（十字架）.

This is a black-and-white photograph . This photo shows a young mother and her two kids .I would say they must be from somewhere in South America . It looks as though they are in a crowded market , although it is difficult to tell , because you can’t see much of the background .
The mother has her hair up in a bun(圆髻) and a roundish(略圆的 ) face . She hang her eyes , closes her thick lips ,and thinks something about dinner . Sitting on a stone , she looks fed up(感到疲惫的) . Maybe she had a busy day shopping .
