学生用英语套路老师怎么说

If a student is using cliches or tired expressions in English, a teacher might say:

"I've heard that one before. Try using a more original phrase."
"That expression is a little overused. Can you find a different way to say the same thing?"
"Cliches can be a bit lazy. Can you come up with a more creative way to express yourself?"
"It's important to use varied language in your writing and speaking. Can you think of a different way to say that?"

It's important to encourage students to use more varied and original language in their communication, as this can help them to express themselves more effectively and engage their audience more fully.
