Step 3 教师引导、学生自我小结：

现在完成进行时：表示从过去开始一直持续到现在的工作，这个动作可能刚结束，也可能还要继续下去，

常与for two hours, since 1998, all this morning, these few days等表示一段时间的状语连

用。强调“谈论一直做某事”。

现在完成进行时的构成：主语 + have / has been +（现在分词）doing

E.g. I have been cleaning the room all this morning. 我今天一上午都在打扫房间。

否定形式为：主语 + have / has + not + been doing

E.g. I haven’t been seeing a film for a long time. 我好长时间没看电影了。

一般疑问句构成：Have / Has + 主语 + been + doing + 其他?

回答：Yes, 主语 + have/has. No, 主语 + haven’t/hasn’t

E.g. Have you been doing your homework since this morning?

特殊疑问句形式：特殊疑问词 + have / has + 主语 + been + doing + 其他?

E.g. How long has it been raining? 雨下多久了？

注：for表示时间的持续，后跟时间段。表示一段时间，多与带数词的名词连用，谓语需用延续性动词。

（for + 一段时间）

since表示“自从过去某一时间点以来”，后面接时间点，强调动作或状态一直延续到现在，一般用现

在完成时或现在完成进行时。since后可接表时间的名词或名词短语，也可接一个时间状语从句。（since

+ 点时间 or 从句）
