如:(1)He has come 他来了(他现在在这儿)(2)He has turned on the light 他已经把灯打开了(房间是亮的)(3)She has learned to skate 她学过滑冰(她现在会滑冰)(4)He has been to Armenia 他去过美国(他现在不在那里,但知道那里的情况)✧考点探究:1、对这种用法的考查,主要考查学生对现在完成时态的判断。
这种用法强调过去动作对现在造成的影响,因此,在题干中常用一般现在时态或一般将来时态的句子来说明这种影响或结果。
(口诀:前后两句呈因果,必用现在完成时)如:(1)I ___________ (spend) all the money, so I have to walk home.答案为have spent. 花光钱是过去的动作,但对现在造成了影响,“我现在必须得步行回家”。
