请各位英语高手帮忙检查一下这篇英语文章的语法等有木有错误.

内容写得不错哦~有些细节方面的时态和用法替你改过了。文章如下Mrs xu:I am very careless,so my English is not very good。。I am fear of English。When I was a junior high school student,you became my English teacher。Your English is very good。You are my hero。You are kind to us。when i didn't pass the exam,you criticized me with a smile,so I began to focus the importance of English。Although I will become a senior (student) two years later and you will have to retire,I will not forget your smiling face。You are my English teacher。Forever。Finally,happy birthday to you!With best wishesyours sincerelyXXX尽量保持了原句的风格和意思哦。有些地方在将来的使用中希望以后可以注意,1。“so”这个单词翻译为“所以”的时候,一般不写在句子开端,2。”Although。。。,。。。"这个句式表示“虽然。。。,但是。。。”不过在英文的使用中,although是不可以和but放在一起用的,你可以两种方式任选其一,3。with best wishes,这里我没有给你改,但是个人建议两种方案"With my best wishes" 或者"Best wishes"4。要有落款 yours sincerely,的下方写上名字
