吃货高老师
First welcome to our school lab . I am very happy to tell you what we should do before and in the experiment which we do in this lab . Before we get in the lab ,we should make some preparations . When we are in the lab ,we must follow the instruction of our teachers . And we can not touch anything without our teachers' permittion，because some chemical materials are dangerous to our skin . After having done the experiment , we are supposed to put the instrument back to the cupboard . Then we clear the room and eventually close the windows and lock the door. Are you excited about this?

Welcome to our school lab.I'm very happy to introduce our school's lab to you.Well.before doing any experiments,there are a few laboratory safety rules that we must remember.First off,the most important thing is conduct ourself in a responsible manner at all times in the laboratory.As you see ,the students should follow teachers'instructions carefully. If we do not understand a direction or part of a procedure, we need to ask our teacher before proceeding with the activity.Also,students should not touch any equipment, instruments, or other materials in the laboratory area until we are instructed to do so.When leaving the labortory, students need to put back all the instruments back into the cupboard and keep the laboratory clean and tidily.Lastly,we also need to close all the windows and lock the doors of the lab.After my inrtroduction,i hope you understand a bit about the safety rules of the lab in our school.PS我很纠结楼主的身份？你是在汇报还是在跟那朋友介绍？很奇怪的题目，不过偶尽力，希望有用
