how many 和how often的都怎么回答

how many 是问数量,就根据实际的数量来回答,如：
How many students are there in your class?---- There are forty (students in our class).（你们班有多少学生?四十个.）
how often 是问频度,也根据实际回答,如：
How often do you go swimming?----- Once a week.（你多久去游一次泳?每周一次.）how much 是不可数，什么意思，事例，谢了对，how much是问不可数的数量，如：How much did you pay for your new cell phone? ---- 3,000 yuan. （你的新手机你花了多少钱买的？三千元。） 希望对你有启发。如对你有帮助，请记得及时采纳。
