Boys and girls,

Attention, please! I have an announcement to make. On March 19 Mr Smith from London will come to our school and give us a talk on the difference between British English and American English. His talk will be helpful to our English study. It will start at half past two, and end at four o'clock. It's a very good chance. I hope you will not miss it, and try to take notes. It will be given in the meeting-room. That's all. Thank you.
