Step II Explanation 1.

Ask the Ss to point out the sentences that contain the structure as “We have been excavating for many years” in the text and then write down its structure. [HAS / HAVE] + [BEEN] + [VERB+ing]

2.

Explanation 基本用法: ① e.g. I have been waiting for a letter from my parents. It has been raining for three hours. We have been studying here since 2004. 表示__________________________的动作。它通常

和_____________时间状语连用。

② e.g. She has been sweeping the street all day. She is too tired. We have been waiting for you for two hours. We don't want to wait any longer. 表示_________________________________的动作。

常用句型

①肯定句: e.g. I have been sitting here all the afternoon. He has been collecting all kinds of stamps since he was ten years old. 结构：________________________ ②

否定句：e.g. They haven't been meeting each other for five years. He hasn't been teaching here these years.

结构：________________________ ③

注意事项

有些不能用现在进行时的动词，如 be, have, like, love, know, see, hear 等，同样也不能用现在

完成进行时，而应用现在完成时。例如：

The poor woman has been ill for a long time. Have you seen her parents these days?

时态对比

①现在完成进行时与现在进行时比较：

Susan has been reading that storybook since last night. Susan is reading a storybook now. 现在完成进行时强调________________________；而现在进行时只指________________________。

②现在完成进行时和现在完成时比较：



有些动词(如：work, study, live, teach 等)用现在完成进行时与现在完成时表达的意思差不多。试

比较：

The teacher has been teaching at this school for ten years. The teacher has taught at this school for ten years. 

英语中的多数动词在这两种时态中表示不同的含义。现在完成时如果不带表示一段时间的状语，就只能表示动作的完成，而现在完成进行时则表示动作的延续。试比较：

They have built a new lab. (表示________________) They have been building a new lab (these years). (无论用时间状语还是不用时间状语，都表示__________________) Step ⅢConsolidation 1.

Discuss those given the different answers with students.
