If your sister studies languages, she might as well be a saddle teacher! I'm Mr. Saddle. I'm from the Foreign Languages Department. Although Mr. Ma 'an's teacher is poor, his teaching is not bad, especially in language. Many students look at some external conditions when they enter school, which is actually incorrect. When I first came here, I complained about the bad school, but slowly compared with the students who have passed the exam in other schools, you will find that the environment provided by the school is not bad, but I don't know if I am lucky. Moreover, Miss Li is particularly responsible. Before going to college, he said that the teacher would leave after class. Now I know that it's just a one-sided story. I hope you can help your sister think about it. Good luck with your sister's exam.
