教学过程
Step 1.Lead in the class by letting students appreciate the song seasons in the sun Step 2.Review the The Present Perfect Tense to activate their previous knowledge about it. 含义： 1．表示动作在说话之前已经完成，强调过去的动作对现在造成的影响或产生的结果。 通常与already，yet，never，recently等副词及时间状语so far，by now，up till now，before...等连用。 The project has already been finished. 工程已完成了。(结果是现在不用做这项工作了) The doctor hasn't been sent for yet. 还没有派人去请医生。(现在应派人去请医生) 2．表示一个动作或状态开始于过去，持续到现在，并有可能持续下去。 常与for或since引导的时间状语连用，或用于How long...？句型中。 The machine has been tested for two hours. 这台机器已经测试了两个小时了。(可能还会继续被修) 3．用在时间或条件等状语从句中，表示将来某时已完成的动作，即用现在完成时的被动语态代替将来完成时的被动语态。 You can go home as soon as your work has been finished. 你的工作一完成就可以回家。 Step 3. Read the pairs of sentences. Underline and compare the different verb forms. Jan’s life has been greatly improved by the Internet. The Internet has greatly improved Jan’s life. Much has been written about the wonders of the World Wide Web. People have written much about the wonders of the World Wide Web. Conclusion: 现在完成时被动语态的构成: Active:主语和动作之间是主动关系 have/has + done Passive:主语和动作之间是被动关系 have/has + been + done Step4: Change the sentences into the present perfect passive voice. I have downloaded the software to help my phone battery last longer. The software has been downloaded to help my phone battery last longer. 2. Someone has lost an identity card. An identity card has been lost. 3. Have you confirmed the Wi-Fi password Has the Wi-Fi password been confirmed 4. Have you pressed the button yet to copy the file Has the button been pressed yet to copy the file 5.Has anyone made a comment about the online database Has a/any comment been made about the online database Step5: Think of your own situation and write a similar poem. Look at the way __________________________ Look at the way _________________________ Look at the way __________________________ Step6: Share your poem with your partner! Example: Step7: Finish the exercises on your exercise book. Appendix: 常与现在完成时连用的时间状语 already 已经(肯定句) yet 已经（否定句或者疑问句） recently/lately 最近 since then 从那时起 ever since 自那以来 ever 曾经 so far 迄今为止 for a long time 很长一段时间 by now 到现在为止 in recent years 在最近几年里 in/during/over the past/last years在过去的几年里 需要注意的点： 1．与一般过去时的区别 一般过去时所表示的动作或状态与现在的情况没有联系，而现在完成时则强调与现在的情况有联系。 The museum was opened to the public last year. The museum has been opened to the public. 2.非延续性动词不与阶段性时间状语语连用 如borrow，finish，begin，buy，marry，open，等构成的现在完成时不能与表示一段时间的状语连用。若要表达相应的意思，则要换成延续性动词或改变句式。 The experiment was finished two weeks ago. It is two weeks since the experiment was finished. 3.动词短语中的介词或副词不可省略。 It is said that the case has been looked into. 4. 带有双宾语的动词变为被动语态时,一般将间接宾语变为被动语态的主语，若将直接宾语变为被动语态的主语时，间接宾语前面要用相应的介词。 The company has given him a chance to work abroad recently. →He has been given a chance to work abroad recently (by the company)． →A chance to work abroad has been given to him recently (by the company)．
