3.What do the Yellow River and the Nile River have in common according to Ella and Yaming?
4.At the end of the conversation, Ella says: "We should protect them by all means." Why does she say this?
She says this because rivers are important for civilizations, history, and daily life, and they may face danger like pollution.
Further thinking
Yaming says the Yellow River is called the "mother river" of China. Why do you think people call a river "mother"? What does this tell us about the relationship between people and rivers?
A river is called "mother" because it gives life to the people along it, just like a mother gives life to her children. It tells us that rivers are not just water – they are part of our identity and history.
