【语法知识】
一、how often引导的特殊疑问句
1. how often 意为＂多久(一次)＂，它引导的特殊疑问句用来询问某动作发生的频率。how often通常是对一些表示频率的副词提问，如：always，usually，often，sometimes，never等，也可以对表示＂多久几次＂之类的频率短语提问，如once a week，twice a year，three times a day等。
—How often do you go back home 你多久回家一次
—Once a week/Often/Sometimes. 一周一次/经常/有时。
2. 注意how often与其他短语的区别
(1)how long主要用来提问动作延续了多长时间，答语通常含有＂for + 一段时间＂、＂since + 时间点＂或since引导的时间状语从句。how long也可以用来询问长度。
—How long can I keep this book 这本书我能借多长时间 —For two weeks. 两周。
—How long is the bridge 这座桥有多长 —About 1,000 meters. 大约1，000米。
(2)how soon用来询问＂过多久＂动作才发生，谓语动词常为终止性动词，时态多为将来时，答语通常为＂in +一段时间＂。
—How soon will you get here 你还有多久能到这里 —In five minutes. 五分钟以后。
(3)how far用来询问两地之间的距离＂有多远＂。
—How far is it from your home to your factory 你家离你的工厂有多远
—About twenty minutes’ walk. 步行大约20分钟。
(4)how much多少钱，用来询问价格或不可数名词的量。
---How much is it --- It's 2 dollars.
(5)how many 多少，用来询问可数名词的数量，后加复数。
---How many books do you have ---Three.
二、频率副词
always (100%) (1)always表示动作重复，状态连续，中间从来没有间断，表示频率最大，意思是＂总是，一直，永远＂。其反义词为never。 (2)always与not连用，表示部分否定，意思是＂不总是＂。 The rich are not always happy. 有钱人未必总幸福。
usually (80%左右) usually的频率仅次于always，意为＂通常＂，表示通常如此，很少例外。 He usually goes to bed at ten o’clock. 他通常在10点睡觉。
often (50%左右) often＂经常，常常＂，强调经常性，表示动作重复，中间有间断， They often go for a walk after supper. 晚饭后，他们常常去散步。
sometimes (30%左右) (1)sometimes表示＂有时，不时，间或＂，表示动作偶尔发生，中间间隔较大 Sometimes he slept at home, sometimes he slept in the office. 他有时在家睡觉，有时在办公室睡觉。
hardly ever (1%-10%左右) (1)hardly ever＂几乎从不，很少＂，所表示的频率已经很少了，相当于seldom。 He hardly ever goes to bed before midnight. 他很少在半夜前就寝。 (2)hardly ever是具有否定意义的副词，不与not连用。
never(0%) (1)never表示＂从来不，未曾，永不＂，频率为零，表示动作或状态从没发生。 (2)通常情况下，句子中用了never，就不用含有否定意义的not，no，nothing等词。
小提示 (1)表示频率的答语有every day，once a week，three times a day等。 (2)对表示频率的副词和短语提问用how often。
