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?how 用于询问动作执行的方式、手段等,译为“怎样”。

—On foot. 步行。
How can I carry the box upstairs? 我怎样才能把这箱子搬到楼上呢?4.询问程度。

How long is the bridge?对于这些问句的回答,要根据实际情况直接回答How often do you go to the movie? Once a month.How far is the nearest post office? It is three kilometers. It is thirty minutes’walk.(一)how many和how much的区别1. 所修饰词的不同how many用来修饰可数名词的复数,它的句式是:How many+复数名词+一般疑问句+?how much用来修饰不可数名词,表示数量,也可单独使用。
2.how many的用法(1)对there be句型中主语的数量如:some, five, only one等提问时,如果主语是可数名词,不管主语是单数还是复数一般都用复数形式提问,因为问话人不知道具体的数量是多少,而且many只能接可数名词复数形式,所以be一定要用are.即用How many+可数名词复数+are there+地点/时间状语?的句型结构.例如:1. There is a book on the desk. (用how many改为特殊疑问句)How many books are there on the desk?2. There are seven days in a week. (对划线部分进行提问)How many days are there in a week?(2)口诀记忆how many在句首,名词复数跟着走,一般问句紧相随,其它成分不要丢.3.how much的用法(1)用来询问事物的数量,后接不可数名词。
例如:How much milk is there in the glass?玻璃杯里有多少牛奶?(2)用来询问事物的重量。
例如:-How much does the pig weigh?这头猪多重?-Eighty kilos.八十公斤。
(3)how much意为“多少钱”时,可单独使用,也可构成词组how much money,但英语中常省略money,用来询问某物的价钱、价格。
(注意:how much询问价格时,它的回答若是中国的货币单位应采用汉语拼音yuan,fen来表示,几角常采用几十分来表示,字母用小写,且不用复数。
例如:-How much is the eraser?这块橡皮擦多少钱?-Ninety two fen.九角二分。
)(4)用来询问数字计算的结果,相当于what。
例如:-How much is three plus one?三加一等于多少?-It's four.等于四。
三、how long,how often,how soon的区别1、how longhow long有以下两个主要意思:1. 表示多长时间,主要用来对一段时间(如three days, four weeks 等)提问。

五、How可以用来对形容词、副词强调构成感叹句。
how 引导的感叹句结构有:1. How + 形容词+ 主语+ 谓语!How beautiful the flowers are! 这些花是多么美丽呀!How beautiful the flowers in the parks are! 公园里的那些花多美啊!2. How + 副词+ 主语+ 谓语!How heavily it is raining! 雨下得是多么大呀!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。
