现在完成时与一般过去时的区别：
• 现在完成时：表示过去发生或已经完成的某一动作
对现在造成的h影a响ve或/结h果as，+或V从过过去去分开词始一直延续到
现在的动作或保存的状态，强调的是现在的情况，不 能和表示过去的时间状语连用（如：in 1990，last Sunday 等）。
• 一般过去时：一般过去时只表示过去的动作或状态， 和现在不发生关系（即动作或状态在现在已经结束）， 它可以和表示过去的时间状语连用。
现在完成时把过去的动作和现在的结果联系起来， 一般过去时只限于表示过去的动作本身, 与现在 的结果无关。现在完成时与一般过去时在意义上 的区别举例如下：
I have cleaned my room. (My room is clean now.) 我已经打扫过我的房间了。
I cleaned my room last week. (I did it in the past.) 我上周打扫了我的房间。
