五、重点语法

   1、现在完成进行时

I’ve been putting on weight.我的体重一直在增加。（表示体重从前段时间开始就一直在增加这种状态）

现在完成进行时的构成：   主语 + has/have been + 动词现在分词。

比较：现在完成时：       主语 + has/have + 动词过去分词

现在完成进行时表示从过去开始一直持续到现在，有可能还要持续下去的动作，常与for, since, how long等词连用。

Eg.: She has been watching the talent show(才艺表演) for ten minutes.到现在为止，她看才艺表演已经有十分钟了（表示看才艺表演的状态已经持续了十分钟，而且还将进行下去）

       I’ve been collecting the shells since I was ten years old. 我十岁时起就一直在收集贝壳。

    如果想“询问别人做一件事有多久了”，用以下句型：

       How long have/has + 主语 + 动词现在分词？

       How long have you been collecting the shells?你集贝壳有多长时间了？

    现在完成进行时经常用于How long have you（sb.）been doing sth.这个句型，表示某人做某事多长时间了.

    现在，可以谈论自己的爱好或兴趣持续多长时间了。

Eg.: How long have you been studying English? 可以这样回答：

       I have been studying English for 5 years.

另一种回答方式：I have been studying English since I was ten.

For和since在表示时间时的用法区别：for + 时间段；since + 具体的时间点

Eg.: 1) I have been playing basketball for about ten years.

       2) I’ve been collecting kites for seven months.

       3) He has been watching English movies since 1998.

       4) I have been listening to the music videos since I was seven years old.

2、 另外几个简单句型：

How long have you（sb.）been doing sth.?在一般情况下，也可用其他简单的句型来表达上述意思：

Eg.: 1)    When did you start skating?

              I started skating at eight o’clock.

       2)    How long did you skate?

              I skated for two hours.

3、现在完成进行时与一般过去时和现在进行时的区别

       1）一般过去时：表示过去发生的事，常与表示过去的时间状语连用。需要注意的是，只要有表示过去的时间，就不能用现在完成进行时。因此，不能说：

eg.:  I have been skating at eight o’clock.(X)

       I have been skating since eight o’clock.(√)    

Or:  I have been skating for two hours. (√)

2）现在进行时：只表示这个动作现在正在进行，或现阶段正在进行。

Eg.: I am skating now.

       Students are watching English movies in the classroom.
