Today is the third day in America. We had classes in the morning. In class we made a cube and a triangular pyramid. It was interesting. I have learnt that triangles are stable. We also visited the school yard of Berkeley. It was a really beautiful university. We'd been walking for a long time, so each of us felt tired. Then I fell asleep in the canteen.

In the afternoon, we had a physics lesson. Because of my terrible English, I couldn't understand all of them. How awkward it was! But I still learnt a lot.

What a tiring but happy day!
