Tiger is one of the most valueable animals to human beings today. It is somehow like a cat, but much bigger than it. It lives in the forest, and feeds on small animals.
Nowadays, the number of the wild tiger is becoming small and small. Maybe there will be no tiger any more if people continue cutting the trees, destorying the living environment or hunt the tiger just for the skin. We must stop all these mistakes. We should protect them, because the world without tiger is not a completed one.

Giant Panda is our national treasure, the state can be said for the protection of giant pandas put a lot of human and material resources giant now has been the world's people the protection and care, which is a good thing, of course, the Tibetan antelope as the country's animal protection , The National People have been recognized, however, this tiger? The poor will be extinct Siberian tiger who is going to have a genuine concern and care a little bit?
According to statistics, the Siberian tiger left at present, less than 20, still such a small number of these survive, has had imagined. Two years ago, in the mountains of Huanren, Liaoning found to be a man to die under the presentation of the Siberian tiger, from this we can see that the above countries and the people of the importance we attach to it, this first Manchurian tiger is actually how the dead do not Conclusion, and the other is only from the northeast where hu came to the place where the wonder and the third is the matter did not rise to the national media in particular. This really puzzled the other person you! Is it really the other tiger who fear love is not worth it, it really fate of the Siberian tiger so?
Towering mountains should not unique to human beings, should not have dense forest unique to human beings, rivers clear this should not be unique to human beings, the Siberian tiger survival of this nature should not be unique to human beings. Siberian tiger to the left of a piece of heaven and earth to survive it, the High IQ is the human species, there are still ways to leave that piece of local survival, and the tiger have to leave that piece of the local dead; you save tigers, is the human population control, engage in Family planning, and the Siberian tiger is scarce Rending it! Now we can hear the cries of tigers in the future even the Siberian tiger can be heard the cries.
熙仁专家提醒:孩子们往往以为,只要放下课本或作业就是休息眼睛了,比如玩会儿电脑,看看课外书,甚至闭目养会儿神。其实,这样只能使大脑得到休息,眼睛却依然处于疲劳工作状态。要想真正休息眼睛,最有效的方法就是看5米以外的`东西。在学校时,应到教室外活动10分钟;在家,则应到阳台或窗前向外眺望10分钟。
每当我们随意地翻开报纸,轻松的心情总会被一些沉重的新闻所打破。以下是报纸上摘录的关于校园安全事故的新闻:2006年9月23日18:50时左右,内蒙古二中的学生上完晚自习从教室拥向楼梯。由于学生相互拥挤,一楼楼梯栏杆被挤坏,一些学生摔到在地,后边的学生不知道前面出事仍向前拥挤,结果导致惨剧发生。事故导致死亡21人,伤47人,其中6人重伤。
2003年1月5日,陕西省宝鸡县初中学生在放学下楼时,一个学生不慎踩空,撞到前边同学,后继学生发生拥挤踩踏,造成3名学生死亡,6名学生重伤,13名学生轻伤。
这些触目惊心的数字告诉我们:危险、伤害事故在我们身边频频发生,威胁着我们的生命,这血的教训一次又一次地为我们敲响了安全的警钟:生命诚可贵。
“安全教育”。这是一个老的不能在老的的问题了,从二十多年前我国就开始进行安全教育了。前不久,某校一位初三学生因为上体育课不慎摔倒,头部受了伤,耽误了学业。为什么至今还会出现什么什么地方、发生什么什么事故、死了多少人、伤了多少了人这些事情呢?
同学们,我们拥有花样年华,拥有美好的未来,然而一切的一切都建立在“安全”这一基础上,都需要我们时刻警惕隐患,防范危险事故。
操场上,那些互相追逐打闹的同学,你的脚步是否可以慢一些,再慢一些;楼梯口,那些你拥我挤的同学,你的动作能否轻一点,再轻一点。因为你一个小小的`过错,有时会酿成无法挽回的损失,甚至令花季中的同学过早地凋谢了。所以无论你出于何种原因,请你优先考虑生命安全,想想自己的亲人,想想自己的朋友,更想想自己的所作所为将带来的后果,想象因为你的父母、朋友、老师,将要承受怎样的打击?
绿色对眼睛有好处,并不是指绿色本身对眼睛有什么好处,而是说远眺大自然的景物可缓解眼睛的疲劳状态。如果看33厘米以内的东西,即使是绿色的,对眼睛也没有益处。
