Chinese Students and the Use of "Too"

"I want to have too much money!" is a sentence the students will often say to me.  And so I have constantly had to correct the students on their use of the word "too."

Recently, I choose to talk about Germany in one of my speaker's corners.  During the class, a student said this about the Germans:  "they killed too many Jews."  I had to quickly admonish her and tease her for having saying that.  "Do you mean to say that was a proper amount of Jews the Germans should have killed?"
