Betty is a smart little girl. She is always asking questions. “Mum, why is the sky blue?” Betty `1.`asks.
Little Betty `2.`really wants to know the answer. “Why is it not white, yellow or green?”
Betty's mother `3.`looks at her daughter. The answer is not easy to understand. But she tries to answer the question for Betty.
So she says, “The sun gives off different `4.`colours of light—red, orange, yellow, green, blue and purple. When the light travels to the earth, it meets the small particles in the air. The light hits `5.`these particles and spreads the different colours all over the sky. Blue light spreads the most. This is why we see a blue sky. ” Betty understands a little now. When she grows up, she will understand more.

答案： 1. asks 2. really 3. looks at 4. colours 5. these
