　　Climbing is my favorite outdoor -activity.  I'm fond of it very much,  especially in late spring.

　　Today, early in the moming, my friends and I put on our sports shoes and started off.  After climbing for half an hour,  we got to the top of the hill. There we had a very good view miles around.  To the morth ,  a big river is crossing the city.  There are many ships sailing busily.  A lot of trees are there, too.

　　It was time for us to go back when the sun started to go down.  On the way back, we were laughing and talking all the time. We had a good time today.
