My hero英语作文
This is our lab.Now I will tell you something about how we use it.Before we come to the lab,we should get prepared for it.We should take the test tubes or other things we need.When we are in the lab,we should follow the teacher's instructions.We mustn't touch anything without permission.Some experiments may be dangerous.So we should do as the teacher tells us to.When we leave the lab,we should put the intruments back in the cupboard.And we should clean the lab,close the window and lock the door.
