(3)现在完成时与一般过去时的用法比较
①一般过去时只单纯表示过去，和现在不发生联系，它可以和确定的表示过去的时间状语连用。而现在完成时表示某一完成的动作对现在造成的影响或结果，强调的是现在的情况，所以不能和确定的过去的时间状语连用。如：
We have visited the farm(现在对农场有所了解)
We visited the farm last week(说明上周参观农场这件事)
②如果询问某事发生的时间、地点只能用一般过去时。如：
When did you lose your cat?
I lost it last night.
I found it in the garden.
