我来献丑一下~

I am Li Hua, Secretary of the Science Department of Three Georges High School's Students' Committee.

We sincerely invite you to take part in our school's Science Art Day. In addition, we hope you can give a speech with regards to 'How Science Can Be Related to Art'.

There will also be a Teacher-Student Party at the end of the event and we hope you will able to attend that as well.

Please honour us with your presence and we sincerely await your favourable reply.

One more thing, pay attention to the handwriting.
