福州市连江华侨邱兴妹

学情分析:本班的学生英语综合能力总体相对薄弱,很多学生对语法知识都是一知半解的。其中时态更是他们易于混淆的语法点,所以本节的复习课采用歌曲导入，在由课文原句做铺垫对现在完成进行时进行归纳，最后在和完成时进行比较。

1. Target language:Grammar---

the Present perfect continuous tense.

2. Ability goals ：Enable the students to use the present perfect continuous tense. 3.Learning ability goals ：

Help the students learn how to use the present perfect continuous tense. 4.Teaching important & difficult points ：

How to use the present perfect continuous tense properly. 5.Teaching methods：Explanation and practice 6.Teaching procedures & ways : Step ⅠLead-in 1.Enjoy a song and pay attention to the lyrics , leading to the theme : the present perfect continuous tense.（引起学生的兴趣和了解现在完成进行时的）

2.Ask the students to point out the sentences in the reading that contain the Present Perfect Continuous.（从刚学完的文本中找相关的句子，从寻找归纳中增强孩子的自信心）

Sample sentences: (1).We have been excavating here for many years (2).We have been finding the bones of tigers and bears in the caves and we think these were their most dangerous enemies.

(3)

.We have been excavating layers of ash almost six meters thick, which suggests that they might have kept the fire burning all winter. T: What is the same structure in these sentences? S: “have/ has been doing...”

1

T: Yes, in this unit, we will learn “have/has been doing sth.” That is the present perfect continuous tense.

Step Ⅱ Explanation Present Perfect Continuous Form：have/has been doing Usage: Use 1: Duration from the past until now

Let the students describe the two pictures on the screen using the Present Perfect Continuous . Sample answers: ☆My younger brother has been surfing the Internet all the time. ☆Aren’t you tired？

You have been jumping for three hours. 总结：过去某时开始一直延续至今的动作，可能还要继续进行表示动作从过去某一时刻开始，一直延续到现在，现在这个动作可能刚刚终止，也可能仍然在进行着。经常与for, since,all/morning/day/week,all the timed等用在一起。. Use 2:

Let the students describe the two pictures using the Present Perfect Continuous. ☆Tom has been phoning Alice every night for several months. ☆You’ve been saying you can succeed for five years.

意义：表重复。叙述从过去某时到现在或最近一再重复的动作或存在的状态,并不是在一直不停地进行。

Use3: T:Please describe the two pictures using the Present Perfect Continuous. ☆Oh, you have come at last! I have been waiting for you for two long hours. ☆You are here! I have been looking for you long. 意义：叙述从过去某时开始一直继续到现在，但不再继续下去的事情。－－带有浓厚的感情色彩，强调持续了“那么久”或做得“那么辛苦”。

（从三个方面的例句和解释让学生明确现在完成进行时使用的场合以及所表达的意义）

StepⅧ Teaching Reflection

1.

语法讲解应进一步细致切题，从而避免学生在做题中出错。

如：讲解中应加上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。这样学生就不会犯have not been seeing you这样的错误。

2.

语法的掌握要注重“理解－记忆－练习”三步骤，学生需反复练习，练习题可以尝试使用多种教学方法，除了单项选择题外，填空题，补全对话，改写句子等形式都可训练其对语法知识的运用能力，也确实能够提高学生的兴趣。

3.

应给学生更多的时间自己总结语法，自己质疑，达到自主学习的目的。
