高中英语现在完成时学习方法一

       1.现在完成时用法基本概念：表示过去发生的动作对现在造成的影响或结果;或表示过去已经开始，持续到现在的动作或状态。

　　2.现在完成时用法基本构成：助动词have/has+过去分词 过去分词的变化规则： 规则动词的过去分词由动词原形加ed构成,不规则动词的过去分词 见不规则动词表(教师给学生复印)

        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
