现在完成时和现在完成进行时讲稿

第一讲 现在完成时和现在完成进行时

Summary:

英语的动词时态有四种:一般时态、进行时态、完成时态和完成进行时态。现在完成时

的构成公式为:have/has+过去分词;

现在完成进行时的构成公式为:have/has been +现在分词。 现在完成时的基本例句:

1) We have lived here since1995. 2) I have been to Japan twice. 3) Joan has just finished her homework

其中,(2)(3)描述的是过去发生而与现在情况有关的事物或状态,(1)描述的是从过去某时到现在为止这一段时间中发生的情况。

▲ 总之,现在完成时表现的是从过去到现在的事情。 一、 现在完成时的形式 A→现在完成时的肯定句

句型:主语(I、we、you第三人称复数)+have+过去分词 主语(第三人称单数)+has+过去分词 例:1)I have been busy all the day.

2) My father has read today’s paper. 3) I have just written the letter. B→现在完成时的否定句

句型:主语 + have/has + not + 过去分词

进行。

1)主动语态:主语+have/has+现在分词(doing) 2)被动语态:主语+have/has been+过去分词(done) 例:Have you been waiting for him all the day? 2、用法

a.在强调动作还未结束,还要继续下去时,不能用现在完成时,而要用现在完成进行时。 例:I’ve been writing the composition for two hours,but I haven’t finished it yet. b. 动作不包含持续意思的动词,要用现在完成进行时,表示延续到现在的动作。 例:The artist has been painting the painting.

c. 现在完成进行时也用来表示一种在现在以前这个阶段反复发生的事。 例:He has promsing me to help you.Hasn’t he done it? d. 有些动词不能用于现在完成进行时,但可用于现在完成时。 1)表状态的动词 be, have,exist
