He has been repairing the car. 2.I have been learning English since three years ago. 【归纳拓展】 现在完成进行时态，其构成为：have/has＋been＋doing。表示动作从过去的某一时间开始，一直持续到现在，或者刚刚终止，或者可能仍然要继续下去。 Tom’s hands are very dirty. He has been repairing the car. 汤姆的手很脏。他一直在修理汽车。 I have been learning English since three years ago. 三年以来我一直在学英语。 【易混辨析】 时态 含义 现在完成时 (have/has done) 强调的是某个刚刚完成的动作或某个动作对现在的影响或产生的结果。 现在完成进行时 (have/has been doing) 表示过去的动作持续到现在并有可能延续下去，也可表示重复性动作，还可表示某种感情色彩。 I have been writing a letter. 我一直在写一封信。(还在写) I have written a letter. 我已经写了一封信。(已写完) 【针对练习】 单句语法填空 (1)Cathy is taking notes of the grammatical rules in class at Sunshine School, where she ______________ (learn)English for a year.
