鲸鱼知多少
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。
鯨为适应水中生活,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—抹香鲸能澘至干米以下,并在水中持续243175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:
Pandas are black and white animals. Most of them live in the forests. Some live in zoos or research centers. They eat bamboo. They can climb trees. One interesting fact is that they love sleeping. Pandas are so cute and lovely that they have become a symbol of China.
But now pandas are in danger because pandas don't have many babies, maybe only one every two years. people cut down many forests so that they can't find enough to eat.
We should protect pandas from learning more about pandas and the rules on pandas protection. I think people should stop cutting down the forest and plant more bamboo for them. The government can set up nature reserves to protect them. Let's do together. I believe there will be more and more pandas in the future.

Why should we protect wild animals
Do you know any endangered animals？Why are they in danger？①
I think there are many endangered animals in the world，such as② tigers and pandas.When people cut down trees，tigers can no longer hide and hunt.Many tigers are killed by people who want to sell their fur for money.③
And there are few places where pandas can live.
We are not alone in the world.We human beings could not live without all the plants and animals around us.So protecting wildlife animals is very important.We must take measures to keep plants from being destroyed and stop animals from being killed.④ We all hope that in the future there will be a lot more forests and wild animals.⑤
