Sample 1
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 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.
Writing
Sample 2
Whales are very huge animals. They live in the sea. Usually they eat small fish and other sea life. There are about ninety-eight kinds of whales in the world. One interesting fact is that whales can sing songs. In fact, that’s how they communicate with each other.
Now some kinds of whales are in danger because humans catch them for meat, fat and oil. Some people use whale oil to make things like candles and soap and sell them for money. What’s worse, water pollution is one of the main reasons for their death.
Let’s do something to save the whales. For example, we could protect whales by making laws. And we should provide a clean home for whales by not putting rubbish into the sea. Last but not least, let’s remember: No trading, no killing!
Thinking
No trading, no killing！
