Mum is taking some photos of the vegetables, fruit and farm animals on the farm. My sister and I are picking apples. "We have to go back to Mars (火星), "Dad calls us in our flying car.
"OK, Dad. We're coming, "I say. "Just let me get more. "
"I don't hope you are planning to take all those with us, "says Dad.
"Why not? They are different from the ones on Mars, "I say.
"Dear, "says Dad," we also have lots of apples on Mars."
"But these are Earth(地球)apples, Dad, "says my sister.
Dadkeeps silentfor a few minutes. Then he says, "OK. Let's hurry. There will be traffic jams(堵塞) in the air. "
Yes, my family live on Mars now. Why? Because there are too many people on the Earth. Lots of people have to move to Mars. There are all kinds of trees, flowers and animals on it. There are many schools, hospitals, hotels, post offices and shops on it. There are usually traffic jams in the air at weekends because lots of people go back to the Earth. Mars is great but the Earth is always our first home. We love it more!
