I play football on Saturday.对play football划线提问

What do you do on Saturday?

They often play football on weekend.(划线提问，play football划线）

What do they often do on weekend?

I often play football.划线部分提问

这句话是主语（I）+状语（often）+谓语+宾语（play football）的形式。划线部分是play football 也就是对动作提问，这种情况下用what代替动作置于句首，将语序换为一般疑问句，为满足一般疑问句格式需要加助动词do,然后用实义动词do代替原来的动作play football
所以答案是 What do you often do?
这种题目如果有不懂的也许是你对句子成分和特殊疑问词不太了解，你可以用上述方法再试试回答①对I作为划线部分提问②对often作为划线部分的提问
答案:Who often plays football?
How often do you play football?
