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.

保护鲸鱼的英语作文200词【三】
有人以为鲸鱼是大鱼，实际它是哺乳动物，而且是一种生活在海洋里的哺乳动物。
鲸是属于脊索动物门、脊椎动物亚、哺乳纲、真兽亚纲，包含了大约九十八种生活在海洋、河流中胎生哺乳动物。
鲸怀孕期一般在十二个月左右，鲸在自然环境中，大约二到三年生一个孩子，幼鲸哺乳期在十个月左右。
鲸主要分为两种类：须鲸和齿鲸，海豚和鲸也是一个种类的。
须鲸分别有：蓝鲸、长须鲸、座头鲸、灰鲸等种类。
须鲸的种类不多，但体型巨大，须鲸最小也要超过六米，所以须鲸的体型是很大的。
齿鲸分别有：抹香鲸、白暨鲸、海鲸等类，一般都是齿鲸。
齿鲸的体型一般不是很大（除了抹香鲸），最大大约是二十米，齿鲸比须鲸可就小多了。
抹香鲸是齿鲸类的，身体长十八米，体重五十吨，是体型最大的齿鲸，它的头部很大，要占体形的三分之一，下颌比较小，下颌还有牙齿，喜欢吃乌贼。
它的潜水力超强，是潜水最深，潜水时间最长的哺乳动物。
虎鲸也是齿鲸类的，它的身长为八至十米，体型大约九吨，头部很圆，身体黑、白两色。
下颌的每齿列有十到十二枚齿，嘴巴很长，牙齿锋利，性情很凶，常常进攻猎物，连大白鲨都打得过。
蓝鲸是须鲸类的，一种海洋哺乳动物，蓝鲸已被认为是地球上体积最大的动物，长达三十三米，重达一百八十一吨，背部是青灰色的，不过在水中的颜色比较淡，蓝鲸的头部还会喷水。
须鲸和齿鲸吃的东西可是不一样的，须鲸主要吃磷虾等东西。
齿鲸大约什么都吃，主要吃乌贼、鱿鱼、甲壳类、鱼类为食。
当鲸在海洋里去后，它的身体会沉入海底下，所以生物学家给这个现象一个名字——鲸落。
一座鲸鱼的尸体，可以供养中小型的海洋生物，长达百年才消失。

1。thereof
以”there”为前缀加上介词构成的词，如thereafter， thereby， therein， thereinafter， thereinbefore， thereon， thereof， thereunder， thereupon， therewith等，在文中具体指什么，需要读者依照合同的上下文来判断，因而理解起来比较复杂，请看下例：
This Agreement is written in the English language。 In case of any discrepancy between the English version and any translation thereof， the English text shall govern。 句中”the English version and any translation thereof”从上下文判断意为 “the English version and any translation of the English version”，即thereof一词代替of the English version。与以here开头的词如hereof的理解方法类似。
2。therein
该词意为in that， in that particular
context， in that respect，“在那里”，“在那点上”，“在那方面”，表示上文已提及的“合同中的”“工程中的”。如：the contract or any part thereof意为the contract or any part of the contract，合同或合同的任何部分。
3。thereto
该词意为：to that，“随附”，“附之”，如：“Contract Products” means the products specified in Appendix 2 to this Contract， together with all improvements and modifications thereof or developments with respect thereto。 句中or developments with respect thereto 意为：or developments with respect to the developments。
4。thereunder
该词意为：under that， “在其下”，“依照”，如：The Borrower fails to pay any amount payable thereunder as and when such amount shall become payable。 句中any amount payable thereunder意为any amount payable under the contract。
