1. I think teachers need to be strict.
Strict adj. 严厉的，严格的，多用句型 be strict with sb. , be strict in sth.
eg：
The teacher is very strict with his students.
He is very strict in our homework.
2. It doesn’t matter if a teacher is not organized.
注意句型 it matters +（to sb.）+if 从句（wh-从句）（对某人而言）……是重要的
eg：
It matters little if I miss my bus. 即使我没搭上公共汽车也没什么大不了的。
