What are they
鲸的体型是世界上存在的动物中最大的，鲸是终生生活在水中的哺乳动物，对水的依赖程度很大，以致它们一旦离开了水便无法生活，鲸形状像鱼，鼻孔在头的上部，用肺呼吸。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 sea animals. They live in the sea. They eat small fish and other sea animals. They can jump high out of water. One interesting fact is that some kids have teeth. Another interesting fact is that they can sing songs.
But now some kinds of whales are in danger because humans catch them for meat, fat, and oil, and use whale parts to make candles and soap. Whales are also in danger from water pollution.
We should protect whales from learning more about whales and the rules on whale protection. I think people should stop putting rubbish into the sea.
Sample writing:
