Present Perfect ProgressivePresent perfect progressive tense describes an action that began in the past, continues in the present, and may continue into the future. This tense is formed by using has/have been and the present participle of the verb (the verb form ending in -ing).The CEO has been considering a transfer to the state of Texas where profits would be larger.Step2. 现在完成进行时 Present Perfect Continuous Tense过去发生的动作，刚刚结束或最近刚结束（因此，有一个结果就出现在现在）。注意，与现在完成时的不同，现在完成时指的是状态；而这里强调的是动作。与现在完成时相同的地方都是强调对现在的影响。一般来说，用于如下两种情况：1.过去的动作刚刚结束，对现在有影响。例如： I am very tired because I have been running. 2.从过去一直持续到现在的动作。I have been working for 8 hours. She has been waiting since last night.这里的 for 和 since 用法和现在完成时相同。 Step3. 与现在完成时的区别：现在完成时表示到现在为止，动作完成了，而现在完成进行时表示的是一直持续到现在的动作，是比较如下两个句子：I have just read Tolstoys “War and Peace“. 我已经读过了托尔斯泰的战争与和平 。 （已经读完了） 课题Unit 6 How long have you been collecting shells?period 1I have been reading Tolstoys “War and Peace“我一直在读托尔斯泰的战争与和平 。 （从过去开始读，现在还没有读完） 当然，也有意思基本相同的情况：I have lived in Japan for 3 years.=I have been living in Japan for 3 years.Step 3. 怎样区别现在完成时和现在完成进行时比较一下现在完成时和现在完成进行时。在比较这两个时态时，关键在于对现在完成进行时的基本概念是否理解，因为对于现在完成时我们已经有了一个基本的理解了。现在完成进行时是一兼有现在完成时和现在进行时二者基本特点的时态。由于它有现在完成时的特点，所以它可以表示某一动作对现在产生的结果或影响。由于它有现在进行时的特点，所以它也可以表示某一动作的延续性、临时性、重复性、生动性乃至感情色彩。现在就现在完成进行时的这些特点和现在完成时作一简单的比较：（1）现在完成进行时和现在完成时皆可表示动作对现在产生的结果，但前者所表示的结果是直接的，而后者所表示的则是最后的结果。如：We have been cleaning the classroom （a）We have cleaned the classroom （b）（a）句可译为“我们打扫教室来着。 ”其直接结果可能是：我们身上都是灰。（b）句可以译为“我们把教室打扫过了。 ”其结果是：现在教室很清洁，可以用了。又， （a）句表示教室刚刚打扫过， （b）句则可能表示教室是昨天打扫的。Be careful! John has been painting the door （a）John has painted the door （b）（a）句表示约翰刚刚把门油漆过，现在油漆还未干，所以你要小心。 （b）句则无此含义，油漆可能已干了。（2）现在完成进行时有时有延续性，现在完成时往往没有。如：They have been widening the road （a）They have widened the road （b）（a）句的意思是他们在加宽马路，但尚未完工。 （b）句的意思则是已完工了。有时现在完成时有延续性（如一些属于持续体的动词） ，但无临时性质。如：Mr. Smith has been living in London since 1978 （a）Mr. Smith has lived in London since 1979 （b）（a）句有“史密斯先生在伦敦久居”的含义， （b）句则没有。教学后记课题Unit 6 How long have you been collecting shells?period 2（知识 能力 品德）教 学 目 标Topic: HobbiesFunctions: Talk about how long you have been doing thingsStructure: Present prefect progressiveSimple past tensePresent progressive tenseLearning Strategies: Inducing , Cooperating （重点 难点）教 材 分 析Target language:How long have you been skating?Ive been skating since nine oclock.When did you start skating?I started skating at nine oclock.Students are skating at the Hilltop School. 板书设计示意框图Unit 6 How long have you been collecting shells?

I have been teaching here for 15 years.(我一直还要教下去.)一些常见的爱好和特别爱好Whats your hobby?What are the most common hobbies? (最常见的爱好有哪些呢？)1）Common
