考点解读

考点1. How long have you been like this ? 你像这样多久了？

I’ve been like this since last month.自上个月以来我一直都是这样。how long 在此处是“多久，多长时间”的意思，用来询问或谈论某段时间，答语通常用for,since等引导的时间状语，谓语动词必须为延续性动词。如：How long do you stay in Beijing every year? 每年你在北京住多久？How long have they lived here? 他们住在这里有多久了？They have lived here for about two years. 他们住在这里有大约两年了。

【辨析】how long，how soon，how often

how long，how soon和how often都含有how，并且都和“多长时间、多久”有关，但它们的用法不相同。

★how long意为“多久、多长时间”，主要是对一段时间进行提问，答语通常是（for）three days/weeks/months等时间段，它可用于各种时态。

—How long were you not at school last year? 去年你多久没上学？

—About two weeks. 约两周。

★how soon意为“还要多久”，是对从某个基本时间到将来某动作结束或某动作发生这段时间提问，常用在一般将来时态的句子中，其答语通常是“in + 一段时间”。

—How soon can you finish the work? 还要多久你能完成这项工作？

—In half an hour. 半小时后。

★how often意为“多久……次、是否经常”，用来提问在某一特定的时间进行某个动作的次数，答语通常是always，usually，often，sometimes，once/twice a day/month等。

—How often do you see a film? 你多久看一次电影？

—Once a month. 每月一次。
