2019-2020年高中英語 Unit1《Tales of the unexplained》教案1 牛津譯林版必修2 【教學內(nèi)容與教學要求】 一、 教學內(nèi)容： 牛津高中英語模塊二Unit 1（上） 二、教學要求： 1．學會談論有關宇宙空間的簡單話題。 2．學習閱讀英語新聞綜述。 3．理解現(xiàn)在完成時和現(xiàn)在完成進行時的意義和用法。 【知識重點與學習難點】 一、 重要單詞： tale, unexplained, .alien, mystery, technology, monster, sunken(adj) stonehenge, pyramid, disappearance, multi-coloured, nightmare, detective, format, detail, paragraph, Yeti, puzzle(n&v), sighting, witness, creature, research, frighten, case, murder, convincing, evidence, typical, outer, progress, treasure, lately, website, wild, similar, hairy, strength, footprint, existence, inch, exploration, orbit, launch, artificial, astronaut, oxygen. 二、重點詞組： run into碰到, believe in相信（信仰、理論、說法等）, step up加緊, go missing失蹤, show great interest in對….表現(xiàn)出極大的興趣, due to因為, show up露面, according to根據(jù), pull back拉開, do research on在….方面進行研究, rule out排除, look into調(diào)查, make up編造, take charge of負責, make a speech作報告, so far到目前為止, outer space外層空間, human beings人類, space shuttle航天飛機, Soviet Union蘇聯(lián), carry out.完成, 實現(xiàn), 貫徹, 執(zhí)行, dream of夢想, e true實現(xiàn), solar system太陽系, ic strip連環(huán)漫畫. 三、【語法】 A.現(xiàn)在完成時 1．現(xiàn)在完成時態(tài)的構成：現(xiàn)在完成時是由助動詞have/has+過去分詞構成。 2．在現(xiàn)完成時 表示動作完成在過去，強調(diào)對現(xiàn)在造成的影響或結果，常與already，just，ever，never和yet等連用。表示曾去過某處have / has been；表示某人去某處（還沒有回來）用have / has gone。 例如：I have just locked the door. He has left London for York. 3．表示過去已經(jīng)開始，持續(xù)到現(xiàn)在的動作或狀態(tài)，有以下幾種情況： 與for + 表示一段時間的詞組連用。例如：I have worked here for 20 years. 與since + 表示過去某一時刻的詞或詞組連用。例如：They have had 4 meetings since the new term began. 4. 非延續(xù)性動詞與可延續(xù)性動詞 兩者都可用于現(xiàn)在完成時，但非延續(xù)性動詞用在現(xiàn)在完成時時不能與表示一段時間的 時間狀語連用。如果必須這樣用，就需要把非延續(xù)性動詞轉化為可延續(xù)性動詞或狀態(tài)動詞。 He has been back for three days. He has been back since three days ago. It\s three days since he came back. Three days has passed since he came back. B.現(xiàn)在完成進行時 構成：have/has been+doing 現(xiàn)在完成進行時是一兼有現(xiàn)在完成時和現(xiàn)在進行時二者基本特點的時態(tài)。由于它有現(xiàn)在完成時的特點，所以它可以表示某一動作對現(xiàn)在產(chǎn)生的結果或影響。由于它有現(xiàn)在進行時的特點，所以它也可以表示某一動作的延續(xù)性、臨時性、重復性。現(xiàn)在完成進行時比較生動，有時含有明顯的感情色彩,例如: The couple have been quarreling ever since they got married.（說話人對這對夫妻的關系很不以為然） You have been asking me questions for the last two hours.（不耐煩） 1． 現(xiàn)在完成進行時可以用來表示一個動作從過去某時開始一直延續(xù)到說話時刻還在進行。例如： a. He has been working on the puzzle since early morning. b. We have been waiting for the result for half a day. 2． 現(xiàn)在完成進行時可以用來表示一個動作從過去某時開始一直延續(xù)到說話時刻剛剛結束。例如： a. Where have you been? We have been looking for you everywhere. b. I have been wondering about your behavior. 3. 現(xiàn)在完成進行時可以用來表示過去剛剛完成的動作，其結果對現(xiàn)在有影響或聯(lián)系，例如： a. She has been crying(她現(xiàn)在眼睛還在紅腫). b. It has been snowing.(地上已經(jīng)有了一層雪). 【難點講解】 1. The world we live in today is full of mysteries unsolved even by today’s advanced science and technology. 我們生活的世界里充滿了謎團, 這些謎團即使是當今發(fā)達的科學技術也無法解開。 過去分詞短語unsolved even by today’s advanced science and technology是mysteries的定語，它的作用相當于定語從句which are unsolved even by today’s advanced science and technology。當定語從句是由關系代詞＋be動詞＋過去分詞或現(xiàn)在分詞短語構成時，關系代詞和be動詞可以省略。例如： Stories (which were) made up by him didn’t sound very convincing. People (who are) living in these areas believe in ghosts. Advanced 先進的、發(fā)達的。 2. Police in America have stepped up their search for a fifteen-year-old boy who went missing in Dover, New Hampshire. 美國警方現(xiàn)已加緊對一名15歲失蹤男孩的搜索，該男孩于兩天前在新罕布什爾州的多佛市失蹤。 step up加緊，如: step up production, step up the campaign, step up the lobby(加緊游說) search在句中作名詞，常見詞組有one’s/the search for（對…的搜索、探求），in search of(為了尋求)。例如： His search for truth has led to one discovery after another. He risked his life in search of truth. Police是集體名詞，形式上永遠是單數(shù)，和復數(shù)動詞連用。 3. People have shown great interest in his disappearance due to sighting of puzzling lights in the sky and reports of alien visits around the time of his disappearance. 公眾對男孩的失蹤表現(xiàn)出極大的興趣，原因是在他失蹤前后有人聲稱看到天空中出現(xiàn)令人迷惑不解的亮光，還有關于外星人造訪地球的報道。 4. Standing inside were lots of white-skinned, strange-looking creatures with large black eyes. （飛碟）里面站著許多白皮膚、樣子奇怪、長著黑色大眼睛的生物。 這是個倒裝句，這句話的正常語序是：Lots of white-skinned, strange-looking creatures with large black eyes were standing inside. 當句子的主語部分太長，或說話人想要強調(diào)對動作的描寫時，可以把現(xiàn)在分詞短語和主語部分的位置交換，形成“現(xiàn)在分詞短語＋be動詞＋主語部分”的倒裝結構。例如： Lying there was a thin, black woman with untidy hair and stony face. ing up is a talk show by our famous host Peter Pan. white-skinned白皮膚的，這是一個由形容詞＋名詞＋ed構成的復合形容詞，中學階段常見的還有: kind-hearted, bold-faced, ill-tempered等。 strange-looking樣子奇怪的。形容詞/副詞＋動詞＋ing也可以構成的復合形容詞，例如：good-looking, easy-going(好相處的), never-ending, ever-lasting. 5. believe和believe in believe+sb表示“相信某人的話”，believe+sth表示“相信某事的真實性”。例如： I believe George, he has never told a lie. Do you believe his story? Believe in+sb表示“信任某人”，believe in+sth表示“相信某事的存在、信仰某種學說或宗教”。例如： I believe in Ed, he will never let me down (讓我失望). I don’t believe in UFO. He believes in Maxism. 6. search和search for search+搜查的對象，例如：search the house, search the prisoner. Search for+，例如：search for gold, search for food. 也可以是：search+搜查的對象＋搜索的目標。例如：search the house for the thief 7. make up編造, make up for補償、彌補, be made up of由….構成. 例如： We had to work day and night to make up for the lost time. He made up this story simply to draw attention to himself. The exploration team was made up of 4 scientists, a doctor and an Indian guide. 8. go作為系動詞用法小結： 1） 表示“變得”，常和有關顏色、狀態(tài)、質(zhì)地的形容詞或詞組連用，例如： a. His hair has gone gray. b. He went purple（發(fā)紫）with anger. c. The pany went broke (破產(chǎn))after such a heavy loss. d. Milk goes bad (變質(zhì))very easily in hot weather. e. The children went wild with excitement (高興地發(fā)狂). f. The project can be finished in a week if nothing goes wrong. 2） 表示“選擇….樣的方式、采用….的方法”，例如：go natural回歸自然, go international國際化, go native融入當?shù)厣鐣? go green追求綠色生活。 3） 表示“未受到…”, 常和un+過去分詞構成的形容詞unpunished/ unnoticed/ unchallenged/ unmented等連用，相當于“pass/get away without being＋過去分詞”，例如： a. Many important details have gone unnoticed while he was listening. b. If his cheating goes unpunished, more students will follow suit（跟著學）. 【同步練習】 一、 單項選擇 1． Nanjing is situated------- the Yangtse River.
