Linda: Hello , Leo. What are you doing these days? I have not seen you after we attended the Club Fair last month.

Leo: hello, Linda. I attended the Solar Power Club last month. Then I began to make some machines and they only used solar power.

Linda: Oh, you attended the Solar Power Club! That sounds interesting! Did you make something by yourself?

Leo: Yes, last Sunday I made a toy car. It could run fast, and I could use a remote control to drive it all around the playground.

Linda: Great! Can you show it to me if you have time?

Leo: Certainly.
