C.He’s brave. D.He’s rude. 25.Why did Farber decide to try acupuncture on pets？（　　） A.He was trained in it at university. B.He was inspired by another veterinarian. C.He benefited from it as a patient. D.He wanted to save money for pet owners. 26.What does paragraph 3 mainly talk about？（　　） A.Steps of a chiropractic treatment. B.The complexity of veterinarians’ work. C.Examples of rare animal diseases. D.The effectiveness of holistic medicine. 27.Why does the author mention the American Holistic Veterinary Medical Association？（　　） A.To prove Farber’s point. B.To emphasize its importance. C.To praise veterinarians. D.To advocate animal protection. （一）由文本积阅读词汇 1.practice v.　　实行，奉行 n. 惯常做法 2.graduate n. （大学）毕业生 3.relief n. （痛苦等的）减轻 4.ease v. （使）减轻 5.suffering n. 疼痛 6.approach n. 方法 7.advocate v. 提倡 （二）由文本积派生（合成）词汇 1.occasionally adv.[派生词] 偶然，偶尔 （occasional＋-ly） 2.conventional adj.[派生词] 依照惯例的，遵循习俗的（convention＋-al） 3.additional adj.[派生词] 附加的，额外的 （addition＋-al） 4.adjustment n.[派生词] 调整，校正 （adjust＋-ment） 5.membership n.[派生词] 会员身份 （member＋-ship） 6.association n.[派生词] 协会，社团，联盟 （associate＋-ion） 7.effectiveness n.[派生词] 有效性，效力 （effective＋-ness） （三）由文本积主题词块 1.ahead of one’s time （观念）超前 2.have the last laugh 笑到最后，取得最后胜利 3.herbal medicine 草药（疗法） 4.start out as 起初是（某身份） 5.an alternative treatment 一种替代疗法 6.a heart condition 心脏病 7.put ...to sleep 给（患病动物）实施安乐死 （四）由文本知变式运用 1.近义替换（用文中的词汇替换） ①began supplying them to pets→　　　　 （第二段） ②a severe heart condition→　　　　　　 （第三段） 2.熟词生义（文章中生义） sleep [熟义] v.睡觉→[生义] 　　　　　　　　　（第三段第二句） （五）由文本学靓丽表达 1.He 　　　　　　　　　　　　　（变得感兴趣） alternative treatments 20 years ago when he suffered from terrible back pain. 2.Then he tried acupuncture， an ancient Chinese practice， and 　　　　　　　　（感到吃惊） that he improved after two or three treatments. （六）由文本学长难句分析 　After Charlie had a heart attack， Tindale says， she was prepared to put him to sleep， but Farber’s treatments eased her dog’s suffering so much that she was able to keep him alive for an additional five months. 逐步还原 Step 1 She was prepared to put him to sleep， but Farber’s treatments eased her dog’s suffering.（主句结构为由but连接的　　　　） Step 2 After Charlie had a heart attack， Tindale says， she was prepared to put him to sleep， but Farber’s treatments eased her dog’s suffering.（加入after引导的　　　　　　　　　　；加入插入语） Step 3 After Charlie had a heart attack， Tindale says， she was prepared to put him to sleep， but Farber’s treatments eased her dog’s suffering so much that she was able to keep him alive for an additional five months.（加入so ...that ...引导的　　　　　　　　） 参考译文：　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 提示：完成课后作业　必修第一册　UNIT 4 8 / 9 学科网（北京）股份有限公司 $
