Teaching procedure

Step 3 explanation

现在完成时: 要点精析：

现在完成进行时表示动作从过去某一时间开始一直延续到现在，其动作可能仍将继续延续下去。

现在完成进行时的基本结构

have/ has been doing

基本用法：

现在完成时表结果, 他的动作发生在过去, 但是对现在有影响, 而这种影响却往往是说话人的兴趣所在。现在完成时跨越两个时间, 一个是过去, 另一个是现在。

e.g.

I have studied English since 2001.

You have been studying English over 11years. 现在完成进行时:

基本用法

1) 强调时间的持续性。如：

电话响了差不多一分钟, 为什么没人接?

The telephone has been ringing for almost a minute. Why doesn’t someone answer it?

2) 表重复。叙述从过去某时到现在或最近已在重复的动作。如：

His brother has been collecting all kinds of stamps since he was 10. 他弟弟从十岁起就一直收集各种各样的邮票

3) 有感情色彩。如：

I have been telling you not to make trouble.我一直劝你不要找麻烦。

现在完成进行时和现在完成时的比较:

现在完成进行时

强调动作的延续性

现在完成时

强调过去某个动作对现在造成的影响或产生的结果

表示动作的反复

不表示动作的反复

例句

I have thinking it over.

I have thought it over.

I have been visiting my hometown recently.

表示生动，含有感情色彩

说明一个事实，一种影响或结果
