今天,到酒店吃饭,一进门就看到玻璃窗里摆着一块白色的东西,我问爸爸那是什么?爸爸说是白鲨鳍,也就是大鲨鱼的翅。一提起鲨鱼,我就想到鱼肝油和宴席上的鱼翅汤,还有电影里的大白鲨,要不就是被吃的形象,要不就是吃人的形象。可爸爸告诉我,鲨鱼在不久将来就会从海洋深处消失,很可能会成为因为人类因素而第一个绝迹的海洋生物。为什么鲨鱼会第一个绝迹呢?因为每年人类***掉的鲨鱼数量高达550万只,而真正数量可能还不止这么多。在我们国家,吃鱼翅代表着财富和尊贵,随着人们收入的增加,人们对鱼翅的需求也越来越多,对捕鱼的人来说也是一笔很大的收入。可是,让人难过的是,渔船捕捉到鲨鱼后,因为鲨鱼很大,占据了船舱,而且吃鲨鱼肉的人很少,所以船员只把鱼翅割下来,就把剩下的鲨鱼放回海里,没有鱼翅的鲨鱼不久就死掉了。
另一个严重的问题是,鲨鱼成熟晚,生小鲨鱼的数量少,而且成长速度慢,大约十年才能长成一条成年的鲨鱼。好不容易长大的鲨鱼,却因为鱼翅而失去了性命,所以鲨鱼越来越少了。那,没有鲨鱼有什么问题呢?爸爸告诉我,大自然的生物链是一个紧密相连的系统,如果我们从生物链的一个环里取出一个物种,其他海洋生物就都跟着灭绝了,所以现在很多国家的动物保护学家都提出要保护鲨鱼。保护鲨鱼是一个很新的概念,它不像保护海豚和保护鲸鱼那么容易被人接受,因为人们都认为鲨鱼很大,很凶恶,很喜欢吃比它小的动物,喜欢吃人。事实上,大多数的鲨鱼,很少超过两米,而且,最大的鲨鱼――鲸鲨主要吃虾蟹。
了解了这些信息,下次再看见桌上的鱼翅,我们是不是该好好重新考虑一下,有没有必要为了一时想吃鱼翅,让一个珍贵的物种从地球上消失呢?
去过很多次银杏公园,说每次都有新的感受,那是扯谎,可也真游出了一点味道。那就是它的幽深,静谧,喧闹中一份少有的从容、淡定。
说起规模,说起景色,它可能都不如生态公园,更不比别的风景名胜。但我认为,好景色凭的不是它有多么五彩斑谰,有多么光彩夺目,而是能给游人怎样的感受。银杏公园给我的感受是淡绿的,是深蓝的,是浅黄的。
若不是淡绿的,又怎能有两岸青翠、一潭绿水呢?从小石子颗颗垒起的路上延伸进去,没有青草,没有鲜花,惟有大树与大树纵横交错,遮挡了裸露在阳光下的小路,带来了一丝清凉,为人们烦乱的心留下一块安然而从容的去处。走尽了石子路,是泥土地。虽说看起来不是那么美观,但有一种凝重的乡土气息,尤其是两边的绿叶,仍给我们带来绿意,带来快乐。
若不是深蓝的,又怎会有一泓碧蓝的湖水?身处此境,心中会泛起蓝色的孤独,激起与夕阳融为一体的粼波。银杏公园的湖水,可是袖珍的,仅那么一潭,没有游艇在湖面呼啸,唯有那波光在闪烁,但是一方净土。我更喜欢静静的`依在一块大石头上,眺望着远方像在动,又像不动的波光。这时候,我有一种可以什么都想,也可以什么都不想的自在悠闲。
若不是浅黄的,又怎会有一片金黄的坡地?金黄,象征着奋斗与希望。由谷地的小路,到高处的小山,爬过一个极陡的山坡,上面皆是黄黄的小草,在风中舞动,似乎在为每个人欢呼,小草给人一种勃勃的生命力和前进的动力。
银杏公园奇特的美:她美在清新脱俗,美在宁静自然,美在幽深静谧。我喜欢这奇妙的风景。
一只小熊猫摘了一只大南瓜,想把它拿回家。但是这只南瓜太大了,她没有办法把这么大的南瓜带回家。
突然她看见一只狗熊骑着一辆自行车朝她这边来。她看着自行车,跳着说:“有了!我有办法了。我可以把南瓜滚回家去。南瓜好像车轮。
于是她把那瓜滚回家。当她妈妈看到这只大南瓜的时候,很惊讶:“天啊!这么食的南瓜!你是怎么把它带回家来的?”小熊猫自豪地说;“我拎不动它,可是我能滚动它啊!”她妈妈微笑着说:“真聪明啊!记住:只要你肯动脑筋,没有难办的事。
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.
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.

A tiger is a kind of catamount animal. It looks like a cat, but much bigger than a cat. A tiger is very ferocious and it eats mainly meat. It has yellow and black streaks all over its body and it looks very beautiful. Its tail is long and strong and it can hit its quarry dying.
Tigers live in the thick forests and small animals in the forests are tigers' food.
During the past years, many forests have been cut down and the living conditions of the tigers are becoming worse and worse. There are fewer tigers left in the world now. Tigers are the animals of the world, and they should have their own living spaces. We must do our best to protect the tigers and their living environment.
从前,有一个巨大的一个森林,里面住着许多的小动物,比如,小兔子乖乖、兔子妈妈、小狗旺旺、狗妈妈、小狐狸拉拉、狐狸妈妈、小松鼠绒绒和绒绒的妈妈……这些动物一直快乐的住在这里。
可是,这个巨大的森林又搬来了一个小猪,名叫鲁鲁,他老是破坏这里的花草树木,而且,他什么都吃,坏极了,这里的动物都讨厌他,可是他倒是挺喜欢自己的。我就讲一下大家是怎么讨厌他的吧!
有一天,下完雨,灵巧的乖乖正在采新鲜的`蘑菇,她边采边唱着歌,开心极了!可是突然,讨厌的鲁鲁来了,鲁鲁看见新鲜的蘑菇,就说:“你把蘑菇给我,我要吃,不然,我就把这里的花和草统统给拔掉。”乖乖想,如果不把蘑菇给鲁鲁,鲁鲁就会把花草都拔光,只好把新鲜的蘑菇给了鲁鲁。
还有一天,可爱的绒绒正在小松树上摘美味的松果,不巧,烦人的鲁鲁又来了,鲁鲁看见美味的松果,立刻说:“绒绒,把美味的松果给我,不然,我就把花和草拔光,绒绒只好把松果给了鲁鲁。
这里的女王知道了就把鲁鲁赶走了,从此,这个地方就安宁了。
