Dear parents,
I am writing this letter to invite you to take part in our school's library opening. It will be held at 9:00 a.m. on Wednesday,8th January on the sports field. If you arrive early,you may get a chance to get one book for free.
First,we will have a speech on reading. After the speech,there will be a classical concert. You can enjoy the music when reading. Lunch time is from 11:30 to 12:30. The opening will be a great opportunity for students to share their ideas on reading too.
We sincerely hope that every parent can spare your time with us this Wednesday. Looking forward to meeting you here!
