Alien: Hello, Amy. 
Amy: Hello, Alien. 
Alien: Oh, What's that? 
Amy: We call them apple trees. Apple trees have many apples on it. 
Alien: Apple? 
Amy: Yes. Here's an apple. 
Alien: It's delicious and juicy. We don't have apple trees on our planet. Can you give me an apple tree? 
Amy: Of course. But you can take an apple seed. It can grow into an apple tree soon. 
Alien: Really? How can I grow a little apple seed into a big apple tree? 
Amy: OK. Let me tell you how to grow it. First, dig a hole and put the apple seed in the hole. Then put the earth back and step lightly on it. And you must water them everyday. 
Alien: It sounds easy. Thank you, Amy. I think our people will taste the apple soon.
