高中英语 写了篇文章请大家看看有没有错误

the idael teacher应该是笔误吧,应该用an ideal teacher（因为这里不是特指）
knowledge不是可数名词,所以应改为much*（个人建议用profound knowledge丰富的知识）第一句话你要表达的意思是“我认为一个理想化的教师应该首先有足够的知识,因为必须要有足够的知识才有资格作为老师”.其实这种表达有点啰嗦.我给你一个改编过的,你参考一下把.
Firstly,an ideal teacher must have profound knowledge.Secondly,he should be friendly to every his friends and be patient with the bad students who badly need our guide and help.He should teach him effective ways in study.Generally speaking,however,an elder teacher is more competent than the younger one.This is my requirement for an ideal teacher.
看来楼主的作文水平还是有待提高的,不过没关系.Practice makes perfect.
