After an exam,you are admitted to go to senior high.The whole things in your senior high school are new and unfamiliar,you may have some wrongs in your new school.You are afraid of having no friends to talk about,and you afraid of new teacher.In your opinion,the previous teachers are the best teachers in the world,you may not meet one again.Don not so nervous,something in senior high is better than middle school.
In senior high,you can learn more interesting knowledge.And you can have aexperiment in lab.Don't afraid of making friends,because people aren't always unfriendly.Also,the teacher can lead us to do better.Although sometime they are strict with us,it is good for you.
The best wishes to you.Hope you have fun going senior high.
