我班上有4个平时表现很好的女生结盟了。她们每天几乎形影不离,我行我素,爱打扮,学习成绩直线下降,仿佛对什么都无所谓,现在学校里的学生都称她们为“四大女侠”。我苦口婆心地劝说她们努力学习,劝她们要成为学习上的朋友,互相鼓励、共同进步,无奈,都无济于事,而且仿佛越来越变本加厉。她们怎么了?我该怎么办? There are 4 girls in my class who usually perform well. They almost daily inseparable, go its own course, love dress, academic performance plummeted, as if nothing of what, and now the school students call them “Four Lady.” I persuaded them to work hard to persuade them to persuade them to become friends in learning, to encourage each other, to make progress together, helpless, are of no avail, and it seems more and more intensified. What happened to me? What should I do?
