Do you always agree with your teacher? Sometimes you might have a different a    to a Maths problem. Or maybe they scold(责备) you when you don’t think you did anything w  .
What do you do then? A story on sina.com said that more and more students choose to s      out and sometimes even shout(喊叫) at their teachers.
It’s i    for students to say what they think. In the past, few Chinese students dared(敢于) to speak d    to their teacher. It was an unwritten rule(不成文的规定) that what the teachers said is always right. But now students are b   to think more of themselves and dare to say what they think right.
But students should choose the right way to speak out. We should respect(尊重) teachers. They are older than you and know more things. So, never use i   words when speaking to them. And don’t make them u    when you don’t agree with them.
Try to find the right time to talk to your teacher. For e   , talk about the problem after class.
R    to talk about it in a friendly way.
