　　 　　　Good morning, dear friends. Welcome to our school. Now please allow me to introduce you to some of our school rules here. As high school students, firstly, we are expected to be neatly dressed when at school. Secondly, it must be made clear that we should never be late for class or leave school before it is over. The school is a place for us to live and study in, so we must keep it clean. Lastly, when you are walking on the road, please remember to keep to the right, and, if you want to go to school by bike, you must have a bicycle permit.
