Unit 3 Section Ⅰ（配套word）-【精讲精练】2026-2027学年高中英语选择性必修第一册（北师大版）

本讲义围绕“野生动植物保护”主题，系统梳理核心词汇（如wildlife, endangered, preserve等）、短语（如die out, be in danger等），结合听力逻辑推理（方式和态度推断）训练，通过重点词汇（destroy, switch等）及句型（宾语从句that不可省略）解析，构建“词汇-听力-语法-应用”的学习支架。 资料亮点在于听力部分以真实对话实例（如Linda丈夫性格、Sophie情绪推断）培养逻辑推理能力，提升思维品质。词汇句型设计“即学活用”练习（如destroy词性转换、switch短语搭配）强化语言能力，补全对话贴近生活情境（垃圾分类、电影讨论）。课中辅助教师策略讲解，课后助力学生巩固知识、查漏补缺。

A．Talkative and friendly. B．Quite and unfriendly. C．Talkative and unfriendly. Text W：Linda is very quiet，but her husband talks too much. M：You are right，and he isn't very friendly. 【分析】　根据听力内容中的Linda，quiet，but her husband等， 我们很容易看出Linda的丈夫不安静(talkative)；从男子话中的not very friendly我们不难推出unfriendly。故此题选C。 　(2024·浙江1月卷)How is Sophie feeling now? A．Confused.　　　 B．Worried. C．Disappointed. Text M：All well, Sophie? W：Hmm...not great.I'm just so down with writing this report. M：Are you almost done with it? W：Far from it.And I'll get it represented in class tomorrow. 【分析】　根据听力内容中的Hmm...not great，so down我们可以推断出 Sophie 感到担忧。故此题选B。 　What's the woman's attitude to “e-books replacing paper books”？ A．Supportive. B．Indifferent. C．Against. Text ... W：I heard even the most famous newspapers are starting to go bankrupt. M: Maybe paper books will disappear someday，too.People are starting to read electronic books. W：I'm pro the idea of “e-books replacing paper books”， but I just wish they could make the experience of reading an e-book more comfortable to our eyes. 【分析】　根据听力内容中I'm pro(赞成，支持)the...paper books可以推出女子的态度还是“赞成的”(supportive)，故此题选A。 [重点词汇] [对应学生用书P73] 1．destroy vt.破坏；毁掉了 destroy sth　摧毁某物 destroy sb　毁掉某人 destruction n.　摧毁；破坏 destructive adj.　有破坏性的 Nearly everything in the city was destroyed. 城市里的一切几乎都被毁掉了。 [即学活用] 单句语法填空/完成句子 ①After such destruction(destroy), many problems in resettlement often arise. ②Those anticancer drugs are effective, but also destructive (destroy) to white blood cells. ③The bridge was destroyed(大桥被毁坏) so we couldn't get across the river. 2．switch vi.& vt.转换；改变 switch(sth)(over)(from sth)to sth　将……转换成…… switch sth between　 A and B　在A和B之间转换 switch sth over/around/round　将……换掉 switch sth (with sth/sb)　将……对调/与……换班 switch sth on/off　开/关(电灯、机器等) Then I get up，go downstairs and switch on the TV in the living room. 然后我起床，下楼，打开起居室里的电视。 One of my classmates asked me if I would mind switching seats with her. 我的一个同学问我是否介意和她交换座位。 [即学活用] 单句语法填空/完成语段 ①There are so many buttons and switches(switch) that I am not sure which one I should turn on. ②The middle-aged sales manager determined to give up his promotion and switched over his lifestyle(改变他的生活方式).He switched his job from the sales department to(把工作从销售部换到) the design department，and since then he has lived a life more comfortably.Occasionally，he can lay on the sofa，switch on(打开) his TV and switch off(关上) the lights，enjoying a favourite movie after work. 3．cut down削减 cut up　切碎 cut off　切断；停止，使与外界隔绝 cut in　插嘴 cut out　剪下 We need to cut the article down to 1，000 words. 我们得把这篇文章压缩到1000字。 Cut down on fatty foods if you want to lose weight. 你如果想减肥，就得少吃高脂食物。 [即学活用] 用cut的相关短语完成句子 ①The water supply was cut off suddenly，which contributed to much inconvenience. ②It's rather impolite to cut in when other people are talking. ③At that time, people who lived there kept the fire burning all winter and used sharpened stone tools to cut up the meat. ④Experts think the amount of homework for the students should be cut down． 4．in danger 处于危险之中 in danger of　处于……的危险之中 out of danger　脱离危险 danger n.　危险 dangerous adj.　危险的 endanger vt.　使处于险境，危及 endangered adj.　濒危的 Once harm is done to the ecosystem，all species will be in danger，including humans. 一旦生态系统遭到破坏，所有物种，包括人类，都将处于危险之中。 [即学活用] 选词填空/用danger的相关短语完成句子 ①We should do what we can to save those endangered species，including tigers which are considered dangerous because they can endanger people's lives. ②(2025·九省联考)The theater where the event was taking place was only about five blocks from the hotel，and the area around the hotel didn't seem particularly dangerous (danger).(endanger/endangered/dangerous) ③I heard Jack had a car accident and was in danger of losing his life, but luckily, he is out of danger now. 5．urgent adj.紧急的，紧迫的，迫切的 It is urgent that...(should) do...　急需…… urge v.　敦促，催促；强烈要求；主张 urge sb to do sth　敦促/力劝某人做某事 urge that...(should) do...　敦促，力劝 urgency n.　紧急，急迫 urgently adv.　急切地；迫切地 It is urgent that those tents (should)be sent to the disaster area. 那些帐篷急需被送到灾区。 We all urged him to go ahead with his plan. 我们都力劝他实施他的计划。 [即学活用] 单句语法填空/一句多译 ①Researchers have found that red can bring a sense of urgency (urge) into our minds. ②I have to break the appointment because I have something urgent(urge) to handle. ③我一打开电视，妈妈就催促我去认真学习。 a．My mother urged me to apply myself to study the moment I switched on the TV. b．My mother urged that I should apply myself to study the moment I switched on the TV. 6．hunt vi.&vt.猎取，猎杀 hunt after　追猎；追逐 hunt for　寻找 hunt n.　狩猎；搜寻 on the hunt for...　在寻找…… hunter n.　猎人，狩猎者 Many people hunt after fame and fortune in their lives but never find it. 许多人一生都在追名逐利，但从来没有得到过。 The police are hunting for further clues. 警方正寻找进一步的线索。 [即学活用] 单句语法填空/完成句子 ①The dog drove the coon(浣熊) up a tree so the hunter(hunt) could shoot him. ②You'll have to hunt for the word in the dictionary. ③It is forbidden to hunt after (追猎) foxes in this season.
