Hello everyone!Now I will perform a calligraphy works for you.In the next 90 seconds,please be patient to watch this video which I've made for you!
I’m a talented boy.I’m good at calligraphy,Chinese paintings,playing the piano,and playing the cucurbit flute.
Look at the paintings,they look very real right?
Look at my calligraphy works.One is a regular script,the other is official script.How beautiful!(You may think why there is no running script.Ha!I’m writing now!)
Now look at here,this is my best friend—the piano.We’ve been friends for 5 years.I can play beautiful songs with him and enjoy the moment.
Can you guess who the little boy is?That was me when I was 8 years old.That was my first show,I so enjoyed that show!
Look!This was our class song which was created by me.
“No pains,no gains.” is my motto.Since my efforts to learn,I’ve made good progress.I will try harder and make more progress.
I believe:I will be soaring up in the sky just like an eagle.
