2017--2018学年人教版选修八Unit 5 Meeting your ancestors grammar课时作业 (2)

第10讲Meeting your ancestors 语法篇____________________________________________________________________________________________________________________________________________________________________1.掌握现在完成进行时的用法；2.能够区分现在完成时与现在完成进行时。

现在完成进行时（1）结构由“have/has been+动词的现在分词”构成，表示从过去某时开始，一直持续到现在的动作，可能刚刚停止，也可能还在继续进行。

例如：We have been looking for you for an hour.我们找了你一个小时。

（动作刚停止）She has been teaching English since she graduated.她毕业后一直在教英语。

(动作还在继续进行)We have been going over maths these days.我们这些天一直在复习数学。

（动作还在继续进行）（2）有时现在完成进行时不是指某动作一直在不停的进行，而是表示一直到说话时为止的一段时间内一再重复的动作，常常带有感情色彩。

例如：She has been saying that 20 times. 这话她已经说了20遍了。

He has been calling on her several times this week. 他这个星期几次来看他。

We have been having a lot of rain recently. 最近雨水很多。

（3）有时现在完成进行时表示刚才或近来发生的动作，也可表示知道说话时为止的一段时间内发生的动作，这一动做到说话时已经结束，而且一般不再继续下去；这种用法主要表示某一动作所产生的结果或对现在的影响。

2018学年度人教版选修8Unit5Meeting yourancestorsPeriod3Learning about language教案设计(Revise the verb tenses <including the Present Perfect ContinuousTenses>)IntroductionIn this period students will be first helped by the teacher to discover and learn to use some useful words and expressions, and then to revise the verb tenses <including the Present Perfect Continuous Tenses>. The following steps of teaching may be taken: warming up by revising the verb tenses <including the Present Perfect Continuous Tenses>, reading aloud to the recording, discovering useful words and expressions, reading more about Davidson Black, revising the present perfect continuous tense, discovering useful structures and closing down by looking and saying. ObjectivesTo help students revise the verb tenses <including the Present Perfect Continuous Tenses>To help students discover and learn to use some useful words and expressionsTo help students discover and learn to use some useful structures Procedures1. Warming up by revising the verb tenses <including the Present Perfect Continuous Tenses>Active TensesTHE PASSIVE TENSES2. Reading aloud to the recordingThe more you read aloud, the better you get at it; the better you get at it, the more you like it; and the more you like it, the more you do it.And the more you read aloud, the more you know; and the more you know, the smarter you grow.So listen and read to the recording of the text. Pay attention to the pronunciation, stress and intonation.3. Discovering useful words and expressionsTurn to page 40 and fill in the blank to complete the two exercises.4. Reading more about Davidson BlackDavidson Black (1884-1934)Davidson Black was born in Toronto, Canada in 1884. He learned early on that good communication skills with other cultures would aide him in learning about them. Black not only befriended the Indians and learnedtheir languages in his early days; he also got along extremely well with his Chinese colleagues. He was always eager to know more and this progressed throughout his life.He earned a degree in Medical Science in 1906 from the University of Toronto, then went back to study comparative anatomy. By 1909, Black was an Anatomy Instructor. After realizing his passion for human evolution, he gained his big break. In 1919 he was offered a position at Peking Union Medical College in China. In 1927, Black began an enormous excavation at Zhoukoudian, which is near Peking. It was there that a hominid lower molar of unusual distinction was discovered. After studying this tooth with intense focus, Black recognized the existence of a previously unknown hominid genus and species. He also pointed out the close relationships among Peking man and Pithecanthropus Erectus.Davidson Black inferred that the Peking man was ‘a thinking being, standing erect, dating to the beginning of the Ice Age.’ Some s cientists were skeptical of Black’s findings, and in 1928, while Black was traveling to validate his beliefs to other scientists, half of a lower jaw was found with three teeth still intact. But the evidence he was really looking for was in the discovery of skull of the first Peking man.In 1932, Black was elected a Fellow of the Royal Society. His hard work and dedication carried him far in his experiments and discoveries, but the stress eventually got to him. He struggled with a congenital heartdefect, which when he overworked would act up. He worked long days at his office, often returning again to work during the night, with very minimal sleep. This obsession eventually lead to his death at age 49, in March of 1934, while working alone in his office at night.5. Revising the present perfect continuous tensePresent Perfect ContinuousFORM Present Perfect Continuous[HAS / HA VE] + [BEEN] + [VERB+ing]EXAMPLES:I have been sitting here for two hours.She has only been studying Japanese for two years.NOTE: When you are using a verb tense with more than one part such as Present Perfect Continuous (has been studying), adverbs often come between the first part and the second part (has only been studying).USE 1Duration from the Past Until NowWe use the Present Perfect Continuous to show that something started in the past and has continued up until now. "For five minutes", "for two weeks", and "since Tuesday" are all durations which can be used with the Present Perfect Continuous.EXAMPLES:They have been talking for the last hour.She has been working at that company for three years.James has been teaching at the University since June.USE 2 Recently, LatelyYou can use the Present Perfect Continuous WITHOUT a duration such as "for five minutes", "for two weeks", and "since Tuesday". Without the durations, the this tense gives a more general meaning of "lately". We often use the words "lately" or "recently" in the sentence to strengthen this meaning.EXAMPLES:Recently, I have been feeling really tired.She has been watching too much television lately.Mary has been feeling a little depressed.IMPORTANTRemember that the Present Perfect Continuous has the meaning of "lately" or "recently." If you use the Present Perfect Continuous in a question such as "Have you been feeling alright?", it suggests that the person looks sick or unhealthy. A question such as "Have you beensmoking?" suggests that you can smell the smoke on the person. Using this tense in a question suggests you can see, smell, hear, or feel the results of the action. It is possible to insult someone by using this tense incorrectly.IMPORTANT Non-Continuous Verbs/ Mixed VerbsIt is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses.To express the idea of Present PerfectContinuous with these exception verbs, youmust use Present Perfect.EXAMPLES:Sam has been having his car for two years. Not CorrectSam has had his car for two years. CorrectACTIVE / PASSIVE Present Perfect ContinuousEXAMPLES:Recently, John has been doing the work. ACTIVERecently, the work has been being done by John. PASSIVENOTE: Present Perfect Continuous is rarely used in its passive form.6. Discovering useful structuresNow turn to page 40 and do exercises 1, 2 and 3.7. Closing down by looking and sayingNow to end this period, let’s look at the photo and say something about our ancestors. How did they live in the old days? What did they do for a living?。

高中英语学习材料***鼎尚图文理制作***unit5 Meeting your ancestorsⅠ.阅读理解AAn exhibition of models, 3-D images and videos has brought the Old Summer Palace, known as Yuanmingyuan, back to life, giving a fascinating insight into the life of China’s royal families. Sun Yuanqing reports.More than a century after it was looted (掠夺) and burned down, Y uanmingyuan has been restored to its former glory in a unique way.Exhibition Glory of the Yuanmingyuan, arouses the history and culture of Yuanmingyuan through models, 3-D images and videos. It is currently on display at the Chinese Culture Center in Moscow in celebration of the China-Russia Tourism Year.“It is a breakthrough in the history of Yuanmingyuan，” says Chen Yanying, co-curator (联合馆长) of the exhibition. “It is not meant to condemn the countries that took part in the turmoil (骚动), instead, it is going to send a positive voice, to let more people learn about and come to visit Yuanmingyuan.”Yuanmingyuan’s cultural relics, artworks and architecture that were looted or destroyed in the late 1800s and early 1900s, have now been brought to life on the touch panels. A miniature model of Haiyantang, the largest European garden in Y uanmingyuan, also made its debut (登场), along with replicas (复制品) of the 12 bronze zodiac animal heads that decorate its fountain.One of the highlights of the event is the various interactive (交互式) programs that allow visitors to not only appreciate, but also take part in the creation process of art, says Chen.“For people who know little about Yuanmingyuan, pictures alone can’t do it，” says Chen. “That’s why we need to develop experience centers to help people in other countries relate to Yuanmingyuan.”In the experience center of royal architecture design, visitors can try to build architecture models, discovering how Chinese architecture takes shape without using nails and glue.In the miniature Banmuyuan Garden, the place where the royal family watched opera, there are handmade embroidered (绣花的) costumes and puppets (木偶), which visitors can try on and pose for photographs with. In the imperial schoolroom, where the princes of the royal family used to study, visitors can learn Chinese calligraphy.语篇解读：本文是一篇说明文。
