2019-2020年人教版高中英語選修七Unit 3《Under the sea》（Period 3）word教案 Teaching aims　　　　　 1．Students will be able to recognize the －ing/being done forms and know the exact meanings of them. 2．Students will be able to use these two forms correctly. Teaching procedures　　　　　 Step 1　Revision Ask students to answer the following questions without referring to the textbook. 1．What did Clancy witness when he ran down to the shore? 2．Why did Clancy run in a hurry? 3．What did Old Tom do when they headed into the bay? 4．What did Old Tom do after George beat the water? 5．What did Clancy witness when they drew near? Suggested answers： 1．He saw a whale throwing itself out of the water and then crashing_down again. 2．Because Clancy had already heard that George didnt like being_kept_waiting. 3．They could see Old Tom swimming by the boat，showing them the way. 4．Tom circled back to the boat，leading them to the hunt again. 5．He could see a whale being_attacked by a pack of about six other killers. Next，ask students to pay attention to the underlined words and lead into the grammar item—“v.－ing”/“being done”． Step 2　Grammar learning 1．現(xiàn)在分詞(－ing 形式)的構(gòu)成。 v．－ing 形式由 “do＋ing” 構(gòu)成，其否定形式是 “not doing”，v.－ing 可以帶賓語或狀語構(gòu)成 v．－ing 短語，沒有人稱和數(shù)的變化，但有時態(tài)和語態(tài)的變化。 2．動詞－ing 形式的被動式分一般式和完成式： (1) 一般式：表示這個被動的動作正在進(jìn)行或與謂語表示的動作同時發(fā)生。 (2) 完成式：強調(diào)這個被動的動作在謂語動詞所表示的動作之前完成。 　　語態(tài)時態(tài) 主動語態(tài) 被動語態(tài) 一般式 (not)doing (not)being done 完成式 (not)having done (not)having been done 　　3.動詞－ing的被動式的句法功能。 (1)作主語。如：So_being_killed_by_sharks was a mon thing. (2)作賓語，用在介詞后或需要帶－ing 形式作賓語的動詞后。如： George didnt like being_kept_waiting. He was terrified of being_abandoned_by_us. Do you remember_having_been_taken to Beijing at the age of ten? (3)作表語。如： What worried the child most was his not_being_allowed_to visit his mother in the hospital. (4)作定語。如： The problem being_discussed is of great importance. (5)作狀語。如： Having_been_shown_around the library，we were taken to see the lab. (6)作補足語。如： As we drew closer，I could see a whale being_attacked by a pack of about six other killers. When we approached him，I saw James being_held_up in the water by Old Tom. [注意] (1)v.－ing 形式的被動式主要在句子中作狀語、賓語補足語和定語。但v.－ing 形式的被動式的完成式，一般在句中作狀語(偶爾作非限定定語)，不作其他成分。 They dont like the_design_of_the_new_bridge_being_built.(正在建造的橋的設(shè)計) Not_having_been_pleted，the museum cant be visited yet.(由于沒有完工……) (2)v.－ing 形式的被動式邏輯主語(即動作的承受者)如果也是主句的主語，就不需要表示出來，但是如果邏輯主語不是主句的主語，就得把v.－ing 形式自己的主語表示出來。如： The whole classroom having_been_cleaned，the students went home happily. (3)在want，need，deserve，require，repay，bear，take等動詞及形容詞worth后，習(xí)慣用動詞－ing的主動形式表示被動意義，相當(dāng)于“to be done”。如： The house wants_cleaning. 這房屋需要打掃。 My watch needs_repairing. 我的手表需要修理。 The way deserves_mentioning. 這個方法值得一提。 These young trees will require_looking_after carefully. 這些小樹需要細(xì)心照顧。 The film is worth_seeing. 這部影片值得一看。 Step 3　Exercises 句型轉(zhuǎn)換(改成帶－ing形式被動結(jié)構(gòu)的簡單句) (1)The hotel which is being built now beside the park was designed by a group of young men. (2)The little girl was eventually aware that her parents abandoned her in the mountainous village. (3)He would e even if we dont invite him.(without) (4)After he had been examined several times，he was told to be healthy. (5)I noticed that some people were taken to the police station. Suggested answers： (1)The hotel being built now beside the park was designed by a group of young men. (2)The little girl was eventually aware of being abandoned by her parents in the mountainous village. (3)He would e without even being invited. (4)After having been examined several times，he was told to be healthy.
