英语水平那么差怎么说

If your Engpsh level is not very good, you can say:

"I'm not very proficient in Engpsh."
"I'm still learning Engpsh."
"My Engpsh skills are a bit pmited."
"I'm not fluent in Engpsh."

It's important to remember that it's okay to not be proficient in a language. It takes time and practice to improve, and it's important to be patient with yourself as you learn.
