howoften,howsoon,howlong区分三“How”问时间意义却不同“how often, how soon, how long”三组词语都可译为“多……”，它们在表时间时很容易让人混淆。

今天，我们隆重推出这三“兄弟”。

A） how oftenhow often常用于询问某动作在单位时间内所发生的次数，是对频度时间状语提问的词语。

频度时间状语可以是often, usually, always, sometimes, never等副词，也可以是once a week, three times a month等副词短语。

与how often相似的短语how many times（多少次），后面常跟限定的时间，如：how many times a week / a day / a month / a year, 并且要回答出次数。

如：-How many times a week does he play basketball?-He plays basketball three times a week.Ｂ） how soonhow soon（多久）主要用来询问某个动作在多久的将来发生，即多久，多快。

它常用在将来时态中，并且用in短语（表示再过多长时间）回答。

如：-How soon will he be back?-He will be back in a month.Ｃ） how longhow long（多久），主要用来询问某个动作或状态所持续的时间。

how long在对句子中带有for或since等表示持续性的时间状语提问时，谓语动词不能是终止性动词。

如：-How long are you staying in New York?-For two years.怎么样？三“How”问时间，意义却不同。

同学们可要分清楚哦。
