Period 2 GrammarPresent Perfect Progressive （现在完成进行时）课前预习使用说明与学法指导：阅读学案上语法部分，完成学案自主学习部分1.

We have been looking for you everywhere.你去哪儿了？我们一直在到处找你。I have just been watching TV.我一直在看电视。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。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。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）现在完成时和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。Weve been living here for ten years.Weve 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。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。Theyve known each other since 1970.自从1970年起他们就相互认识了。结论: 现在完成进行时主要用于表示A. 过去开始而且现在仍在进行的动作;B. 过去开始, 现在刚刚停止的动作;C. 现在看到其直接结果的动作。现在完成时主要用于表示已经完成的动作及其与现在的关系。我的疑问:课内探究：(见情景导学语法部分)课后反思:课后训练：1.完成下列的练习1.
