     here's another joke：

     有一个 穷秀才，他很穷，天天吃不饱。所以 就想办法 去混口饭吃。他有一个挺富裕的朋友，每当人家差不多要开饭时，他就会 到人家家里“拜访”。而且 还编出各种各样的理由，让他朋友 留他下来吃饭。

　　这一天，秀才又“拜访”友人。友人 实在想不出什么理由 让他离开，就打算 看看情形再说。天突然下雨。秀才说：“天下大雨了！”那个富朋友想来想去，就留一张纸条：下雨天留客天留人不留。白话意为：“下雨天就要留客（下雨天留客？）？天留你，但我不留你（天留，人不留）。”富朋友留下纸条后 就走回房间，心想：一会儿再来，看你还好不好 厚脸皮留下。可是一会儿 那个富朋友回来时，还看到秀才在那。就问：“呀，你怎么还在这儿，你不走吗？”秀才就说：“是你叫我留下的啊。”富朋友就奇怪了，问怎么回事。秀才指着那张纸条，：“下雨天留客天，留人不？留！（白话意为：下雨天就是留客天，留人吗？留！）”秀才就笑着说：“你都这么客气了，我还好意思走吗。”那富朋友差点晕过去。<img title="Laughing" src="http://www.italki.com/Scripts/tinymce/jscripts/tiny_mce/plugins/emotions/img/smiley-laughing.gif" alt="Laughing" border="0" />

      古代汉语 文章中的 句子之间 没有标点符号punctuation marks，因此 读书人 从小 就要 学习‘句读（jù dòu）’，即 必须 学习 在读书的时候 懂得在句子之间停顿，此谓‘句或读，连称句读’。其中，句 是语意完整的一小段，读 是句中语意未完、但是语气可停的 更小的段落。（参见：《三字经》中‘明句读’）

      尽管 古代中文 在书写上 原本是 没有标点符号的，但是 读书人 会在文章中 自行 加注记号，如‘？’或‘、’，这 也算是 中文中 最早的 标点符号吧。

In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and scientists from various countries, including those from Maryna's country, believe that the trend is caused mainly by human-induced “greenhouse effect”, though a few organisations hold non-committal positions.

in the United States, conservative think tanks challenged the scientific evidence and they mobilized to undermine the legitimacy of global warming as a social problem. They even propagated their ideas in most media that global warming will have benefits. The refusal to ratify Kyoto Protocol by US government may be one of their success.

The global warming controversy, regarding its causes and consequences, is significantly more pronounced in the popular media than in the scientific literature. unfortunately the causes of increased global average temperature werenot explained convincingly, furthermore, it still remains disputable whether this warming trend is unprecedented or within normal climatic variations, whether humankind has contributed significantly to it, and whether the increase is wholly or partially an artifact of poor measurements. Additional disputes concern estimates of climate sensitivity, predictions of additional warming, and what the consequences of global warming will be.
