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 from water pollution. We should protect whales by making rules on whale protection and by not putting rubbish into the sea. I think people should learn more about whales. 教材解读 Some kinds of whales are in danger because… 某些种类的鲸鱼正处于危险中，因为… in (great) danger“处于(极度)危险之中”，其反义词组为out of danger“脱离危险”。 That country is in great danger. 那个国家处在极度危险中。 【拓展】　 danger(s) of ……的危险、危害 Do you know the dangers of smoking 你知道吸烟的危害吗 Step 3.
