课 堂 导 入
Do you know anything about the whales
Free talk
very large,
live in the sea
鲸是世界上现存的最大的哺乳动物，终生生活在水中，鲸形状像鱼，鼻孔在头的上部，用肺呼吸。体长可达三十米。
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 life. One interesting fact is that whales can jump high out of the water. 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 because of water pollution. We should protect whales by making rules on whale protection and not putting rubbish into the sea. I think people should learn more about whales.
