4.现在完成时与一般过去时的区别： 现在完成时与一般过去时都表示过去的动作，但现在完成时强调这一动作与现在的关系，如对现在产生的影响、结果等;而一般过去时只表示过去的时间内发生的动作或存在的状态，就过去的时间方面讲，只能与一般过去时连用，而不能与现在完成时连用。 Tom has been busy now.汤姆现在很忙。(过去的动作对现在有影响) Tom was busy last week.汤姆上星期很忙。(过去的动作对现在没有影响)
5.判断正误：
1)When have you got here? When did you get here?
2) I have had bought the book two days ago. I have had the book for two days.
3)I have just finished my homework. I have finished my home work a moment ago.
4)Have you ever met an American before? I have met an American last year. 瞬间性动词(也可叫点动词或不延续性动词)表示的动作瞬间即可结束，不能再延续，因此不能与表示延续性的时间状语连用。
5)I have left Wuhan for ten days. I have been away from Wuhan for ten days. It is (has been) ten days since I left Wuhan. Two months has passed since we arrived here. 瞬间动词--------延续性动词：应逐一记忆 become-----be begin to study----study borrow-----keep break------be broken buy---have close----be closed come---be here die-----be dead go-----be away get up---be up have got-have join---be in leave---be away lose----be lost marry---be married open---be open
