扩展资料
1、现在完成时和一般过去时差别在于:现在完成时强调的是动作与现在的关系,即对现在的影响或动作延续到现在;而一般过去时只表示动作在过去某时发生,不表示和现在有关系。因此,句中有过去时间状语时,一般用一般过去时。
I have lost my new bike. 我把新自行车丢了。 (现在还未找到)
I lost my new bike yesterday. 我昨天把新自行车丢了。 (现在找到与否不清楚)
He worked there for three years. 他在那里工作了 3 年。 (现在已不在那里工作)
He has worked there for three years. 他在那里工作已 3 年了。 (现在仍在那里工作)
