预习案

语法讲解：

现在完成进行时

（一）现在完成进行时的构成

现在完成进行时由“have/ has been + 动词的现在分词”构成，第三人称单数用has，其他人称用have。

（二）现在完成进行时的用法

1．表示的动作是发生在过去一直持续到现在的动作这个动作可能刚停止，可能仍继续进行下去，常与延续动词连用。并常接带有表示动作起迄时间的状语，如since last week, since 1997等或由since引导的时间状语从句，也可以带有表示时间长短的状语，如for an hour, for a few days, these days等。例如：

He has been living there since 1970. 他从1970年以来就住在这里。（试与He has lived there since 1970. 比较。）

I have been writing letters.我一直在写信。（试与I have written two letters.比较）

Where have you been? We have been looking for you everywhere.你去哪儿了？我们一直在到处找你。（试与I was looking for you everywhere.比较）

I have just been watching TV. 我一直在看电视。（试与I have watched TV. 比较。）

2．现在完成进行时的动词表示一直到说话为止的一段时间内一再重复的动作。例如：

They have been telephoning you several times in two days.两天内他们给你打过几次电话。The couple have been drinking red tea all the afternoon.这对夫妻一下午都在喝红茶。3．现在完成进行时的动词表示一直到说话时为止的一段时间内，大部分时间都在持续进行的动作（不一定延续到说话的时候），往往暗示这个动作对现状的影响。例如：

What have you been doing this morning? (You look tired.)

你今天早晨干什么了？（你看起来很疲惫。）

You have been reading newspapers. (Newspapers are lying about in your room.)

你一直在读报吧。（你的房间里到处摊着报纸。）

You have been teaching. (Your pocket is covered with chalk dust.) 你刚才在教课吧。（你口袋上有粉笔灰。）

（三）现在完成时与现在完成进行时的区别

1．现在完成进行时更强调动作的延续性，它是现在完成时的强调形式。例如：

We’ve been living here for ten years.

We’ve lived here for ten years.

我们在这儿已经住了十年了。

2．在不和时间状语的情况下，现在完成进行时表示动作仍在进行。而现在完成时则表示动作在过去

已结束。例如：

The students have been preparing for the exam.（还在进行）学生们一直在准备考试。

The students have prepared for the exam.（已经结束）学生们为考试作了准备。

3．有些表示状态、感情、感觉的动词如：have, exist, like, hate, hear, know, sound等动词不能用于现在完成进行时，但可用于现在完成时。例如：

They’ve known each other since 1970.自从1970年起他们就相互认识了。
