鲸的体型是世界上存在的动物中最大的，它是终生生活在水中的哺乳动物，对水的依赖程度很大。鲸形状像鱼，鼻孔在头的上部，用肺呼吸。它体长可达三十米，是现在世界上最大的动物。鲸为适应水中生活，减少阻力，它们的后肢消失，前肢变成划水的浆板。身体成为流线型，酷似鱼。因而它们的潜水能力很强，小型齿鲸可潜至100-300米的水深处，停留4-5分钟，长须鲸可在水下300-500米处待上1小时，最大的齿鲸——抹香鲸能潜至千米以下，并在水中持续2小时之久。

Whales are huge animals. They live in the sea and eat small fish and other sea animals. They can sing songs and sing very well. One interesting fact is whales can jump high out of the water. Another interesting fact is that some kinds even have teeth.
But now some kinds of whales are in danger because there is more and more water pollution. Some people
even catch whales for meat, fat and oil, and use whale parts to make candles and soap.
We should play a part in saving the whales. We could protect whales by making rules on whale protection and by not putting rubbish into the sea. I think people should learn more about whales.

Animals need your help
I like elephants best. Although they are big and strong, they are friendly to human. As far as I know, they are very smart and they are symbols of good luck.
Unfortunately, they are in great danger now. On the one hand, they are losing their home because of farming, on the other hand, people hunt them for their ivory. The number of them is getting smaller and smaller.
In my opinion, it is high time for us to take quick action to protect them. Firstly, the government should pass some lows to forbid killing animals. Secondly, we don’t buy anything made of the ivory. Because just as Yao Ming said, “No trading, no killing.” What’s more, we should raise people's awareness to protect animals and our environment.
Animals are our friends and part a of our environment. Help animals, help ourselves.
全文还巧妙地使用时In my opinion,…, on the one hand,…on the other hand,…,What’s more等句式和短语。
本文结构完整，层次清晰。分段简明扼要地了自己喜欢的动物以及喜欢的原因，同时也分析了大象处境危险的原因。第二段重点突出，提出了保护大象的具体措施。
引用了Extensive language 中的名言“No trading. No killing.”更有说服力。
Help animals, help ourselves

鲸的体型是世界上存在的动物中最大的，它是终生生活在水中的哺乳动物，对水的依赖程度很大。鲸形状像鱼，鼻孔在头的上部，用肺呼吸。它体长可达三十米，是现在世界上最大的动物。鲸为适应水中生活，减少阻力，它们的后肢消失，前肢变成划水的浆板。身体成为流线型，酷似鱼。因而它们的潜水能力很强，小型齿鲸可潜至100-300米的水深处，停留4-5分钟，长须鲸可在水下300-500米处待上1小时，最大的齿鲸——抹香鲸能潜至千米以下，并在水中持续2小时之久。
二、自行完成Self Check。
【合作探究】
本单元谈论的话题是自然之最以及我们可爱的动物朋友们。通过学习应学会用英语介绍某地方的自然风光和特有的动物(动物的保护)等。(正确运用最高级) 根据所提供的信息，展开话题进行描述。
