回答“how+do+you+do?”可以回复对方“How+do+you+do?”。这句话类似于中文的“吃了吗？“，是一种无意义的问候。这句话在现今已经几乎没人用了，通常在日常问候中用”How+are+you?“这样的问句来向对方问好。
How do you do? 回答有I 'm fine，I 'm good 。
how do you do是相对比较正式的问候，常见于60、70年代，现代人见面很少说这句话了。对于how do you do 的回答有三种方式：
1、中规中矩的回复：如果有人问你How do you do?你也可以同样问那人how do you do ?
2、可以用how are you?的回答来应对。举例：
I’m fine, and how are you?
Pretty good, and how do you do?
3、以直接回答Nice to meet you.可以说是非常灵活的。
1．How old问年龄、年代。
How old is your friend?你朋友多大了?
2．How many问可数名词数量。常将可数名词复数紧随其后。如：
How many pictures are there on the wall?墙上有多少幅画?
3．How much询问不可数名词的数量、物品的价格.
How much money is there in the purse?钱包里有多少钱?
4．How long提问物体的长度、时间的长短.
How long does it take you to do your homework every day?
你每天花多长时间做作业?
5．How soon 对 “in+一段时间 ”提问,表示“多久之后”.
How soon will you be back? 你多久后回来?
6．How often对表示频率的副词或短语提问.
How often does she go shopping? 她多久去购一次物?
7．How about用来征求对方意见.
