一、howoften对什么进行提问？
how often指“每隔多久,多久一次做。”，主要用来对频度副词或状语(如：once a day, three times a week 等)提问。
如：A：How often does he come here? 他(每隔)多久来一次?B：Once a month. 每月一次。
A：How often do you visit your mother? 你多长时间看你妈妈一次?B：Once a week. 一周一次。
how often用来提问某动作或状态发生的频率，对“一段时间内发生了几次活动”（always，usually， often， never或twice a day等表示频度的词或短语）提问时用；
eg:How often do his parents let him watch TV?他父母多久让他看一次电视？
对于how often 的句型回答，一般有这些词表示频率：once,twice,three times,four times,everyday等等。
【扩展资料】
大家学习了always, usually, often, sometimes, never等表示时间频度的副词。这些词通常用来说明在一段时间内做某事的多少或某种状态存在的次数的多少。例如：
We usually get up at half past six. 我们通常六点半起床。
Sometimes he goes to see his grandpa on weekends. 周末，他有时候去看望爷爷。
但是，在日常生活中，我们不可能总是用陈述句来表达自己的或他人的一些行动，或者事物所存在的状态。我们还要向对方提出一些问题，请求对方回答。在这种情况下，我们还要用疑问句。请看下面几组对话：
1. —How often do you play football?
—I usually play football after school.
2. —How often does Mary go to the concert?
—She often goes to it on Saturday evening.
3.—How often does my daughter take the medicine?
—Three times a day.
不知大家是否注意到，我们针对上面所说的频度副词和表示“在某段时间内某种动作的次数”的状语提问时，都要用how often。
换句话说，如果要回答由how often提问的句子，我们通常要用频度副词或诸如every day, each week, once a week, twice a day, four times a month等来回答。例如：
4. —How often do you borrow books from the library?
—Twice a month.
5. —How often does your mother do the washing?
—She does it every day.
6. —How often can you go to the movie?
—Once a week.
在大家所做的练习中，常见的有“句型转换”。
这种题型有一种“就划线部分提问”，要求针对陈述句中的划线部分提出问题（也就是把陈述句变成特殊疑问句），其中就有针对上面所说的频度副词或every day, each week, once a week, twice a day, four times a month等提问的句子。
这时候自然要用how often来提问了。
例如：
Jack watches TV three times a week. →How often does Jack watch TV? Our school has a sports meeting twice a year. →How often does your school have a sports meeting?
要注意的是，陈述句在变成这种特殊疑问句时，其结构是：How often+助动词（或系动词 be）+主语+实义动词（如果前面是系动词be的某种形式，则不再用实义动词）+其它成分？
二、howoften造句一问一答五年级简单？
how often 多久一次，对频率提问，通常用于一般现在时；回答时可用频度副词always/usually/often/sometimes等，也可用表示频率的词组once(twice/three times…) a week(month/year…)，例句如下:
How often do you clean your room?你多久打扫房间一次？
I clean it three times a week.
我一周打扫三次。
三、How soon的答句？
Two hours.
就是直接用一个时间来回答，可以是一小时，可以是10分钟，也可以是两天，这个句子他问的就是多久会怎样怎样，所以你就回答时间好了。
还有一个比较容易混淆的词组，how often 这个问的是频率，你可以回答一天两次，一天三次。这两个结构经常是同时考察,大家注意区分。
四、什么句前用how？
①
1. 疑问句中
how +助动词（或者情态动词）＋主语+谓语部分？
How can you do that to me?
How did the boy finish this difficult task?
2. 在从句中，一般引导名词从句
只要把疑问句语序改为陈述句语序
How he succeeded in doing this is still unknown.
I want to know how he can solve this problem.
3. how 可以直接加to不定式，相当于从句
I taught us how to do this experiment.
4. 前面加no matter，用于让步状语从句
No matter how difficult the situation is, the parents tried their best to provide for their children.
5. how用于感叹句
How +形容词（或副词）＋主语＋谓语（或表语）
How lovely the weather is!
How fast time passes!
②
1. 单独用作疑问词.
1． 问身体健康等情况.
How are your parents?你父母身体好吗?
How are things in your father’s factory?你爸爸厂里的情况怎么样?
2． 问天气状况.
How is the weather today?今天天气怎么样?
3．询问方式.

3.How可以用来对形容词、副词强调构成感叹句.

注意以how开头的感叹句与以how开头的特殊疑问句的语序和句末符号是不同的.感叹句主谓不倒装,句末是感叹号,而特殊疑问句主谓要倒装,且句末为问号.试比较：
How far is the factory from here?车站离这儿有多远?（疑问）
How far the factory is from here!车站离这儿多远啊!（感叹）
五、how many times跟how often可以替换么？
how many times跟how often不可以替换。
两者意思不同：how many times意为“多少次”，常用来对once（一次），twice（两次），three times（三次）等表示次数的短语提问。例如：
How many times have you been to Shanghai? 你去过上海多少次？
Twice. 两次。
how often问“频率”，意为“多久一次”，回答时常用once a week（每周一次），twice a month（每月两次）等。例如：
How often do you go to the park?你多久去一次公园？
Once a week. 每周一次。
可以替换，都是表示问频率，多久一次的意思。
六、表示频率的数量词放在句子的哪里？
表示频率的词有always,sometimes,often ,never等 , 它们在句子中的位置是be动词，助动词，情态动词的后面，实意动词的前面
七、什么加频率副词？
频率副词跟在主语之后，谓语动词之前。He always does whatevet he wants.
频率副词短语放在句尾。
She has to take care of her younger
brother everyday.
