It's all in the punctuation:
An English professor wrote the words, "Woman without her man is nothing" on the blackboard and directed his students to punctuate it correctly.
The men wrote: "Woman, without her man, is nothing."
The women wrote: "Woman: Without her, man is nothing."

这是一道点标点题:
一个英语教师在黑板上写上: "女人没有她男人什么也不是" 然后指示他的学生来标点.
男学生写道:"女人,没有她男人,什么也不是."
女学生写道:"女人:没有她,男人什么也不是."
