跪求几句英语

楼上的错好多~~~
Please do not have to tell the teacher 应改为Please do not tell the teacher （语法常识阿！！）

班主任 可不等于teacher in charge，teacher in charge是代课的时候老师可以这么叫。班主任是 head teacher

I knew wrong 改为 I knew I am wrong.

Please don't tell the head teacher, because I know I am wrong.

Please do not have to tell the teacher in charge because I knew wrong

Would you don't tell the headteacher since I know I was wrong?
、上面的那位回答语法有点错误哦

Please do not tell the teacher in charge because I knew wrong

Please do not tell the thing to the head teacher, because I knew my fault.
