Step 2语法精析

一、现在完成进行时的构成：

助动词have/has＋been＋动词-ing形式。

现在完成进行时是兼有现在完成时和现在进行时两者基本特点的时态。由于它有现在完成时的特点，所以它可以表示某一动作对现在产生的结果或影响。由于它有现在进行时的特点，所以它也可以表示某一动作的延续性、临时性、重复性、生动性乃至感情色彩。

二、用法

1．表示从过去某一时间开始一直持续到现在的动作，这个动作是否继续下去，则由上下文决定。它常与表示与现在有关的一段时间的状语连用，如all the time，this week，this month，all night，all the morning，these days，for＋时间段，since＋时间点等连用，还与疑问词how long连用。

She is very tired.She’s been typing letters all day.

她很累。她一整天都在打信件。

I have been waiting for you here for an hour. 我已经在这儿等了你一个小时。

2．表示一直到说话时为止的一段时间内一再重复发生的动作。

You’ve been saying that for five years.

这话你已经说了五年了。

We’ve been seeing each other quite a lot recently.

最近我们经常见面。

[题组训练1] 用所给动词的正确形式填空

(1)Aren’t you tired？You ________________(work) here all day. (2)Here he is！We ________________(wait) anxiously for him since last night. (3)You know，I ________________(look) for a job for three months，and this is my first formal interview. (4)—You haven’t got enough money for your project.

—I know，but I ________________(try) to raise it for the past three weeks. 三、现在完成进行时和现在完成时的区别

1．如果与一段时间连用，两个时态可相互换用，只不过现在完成进行时具有强烈的感情色彩。

I have been learning English for ten years. ＝I have learned English for ten years. 我学英语有十年了。

2．现在完成时可与次数及already，yet，ever连用；而现在完成进行时则不能。

I have been to Hainan three times.我去过海南三次。

Have you ever met such a strange thing? 你遇到过这样奇怪的事情吗？

3．现在完成进行时一般强调过去发生的动作现在仍在继续；现在完成时强调过去发生的动作现在已经完成或表示曾经发生过。

I have been writing an article. 我一直在写一篇文章。(仍在写) I have written an article. 我已写好了一篇文章。(已完成) 4．现在完成进行时表示刚刚结束的动作，强调动作在不久前持续进行，带有感情色彩；现在完成时表示已经结束的动作，强调动作的结果，平铺直叙，无感情色彩。

Where have you been？We have been looking for you everywhere.你到哪里去了？我们到处找你。(表示刚刚结束的动作) We have looked for him，but haven’t found him.

我们找过他，但没有找到他。(表示动作已结束，强调动作的结果) 5．现在完成进行时往往表示动作在重复；现在完成时则常常不带重复性。

(1)Have you been meeting her lately? 你最近一直在见她吗？

(2)Have you met her lately? 你最近见过她吗？

(1)句有“经常相会”之意；(2)句则没有。
