Unit2重点单词用法讲解 2026-2027学年人教版英语九年级上册

第四部分 Unit 2 核心词汇精讲（★★★） 1. admire v.钦佩；赞赏 → admirable adj.令人钦佩的 【教材原句】Who is the person you admire the most? (p.21) 【教材原句】What makes people admirable? (p.23 Section B 引题) 核心用法 admire sb (for sth) 因某事钦佩某人 admirable = 令人钦佩的（形容人/品质/行为） → admiration (n. 钦佩) — 高中词汇，学霸可拓展。 补充例句：I admire my mother for her courage and kindness. 中考链接：admire 是课标核心词，河北中考阅读和写作中要求能正确使用。写作中可替换 like/love 表达"敬佩"。 2. inspiring adj.鼓舞人心的 → inspiration n.灵感；鼓舞人心的人/事 【教材原句】Who inspires us? (p.18 单元标题) / The Inspiring Seed Scientist (p.23) 【教材原句】My biggest inspiration is not a famous person. It's my father. (p.21) 核心用法 inspiring（修饰事物/人）：an inspiring story / an inspiring person inspired（修饰人的感受）：I feel inspired by his story. inspiration：可数（鼓舞人心的人/事）→ an inspiration；不可数（灵感）→ a moment of inspiration 中考链接：inspiring vs inspired 的区别是高中重点，初中只需认识 inspiring 即可。写作中 an inspiring person 是 Unit 2 核心表达。 3. courage n.勇气 → encourage v.鼓励 【教材原句】She is full of courage and wisdom. (p.21) 【教材原句】It's really very nice of him to support and encourage... (p.21) 词形转换链（中考常考） courage (n. 勇气) → encourage (v. 鼓励) → encouragement (n. 鼓励) → encourage sb to do sth → 反义词：discourage (v. 使气馁) → 形容词：courageous (adj. 勇敢的) = brave 常用搭配：have the courage to do sth / full of courage / encourage sb to do sth 中考链接：encourage sb to do sth 是河北中考单项选择/短文填空的高频考点。词形转换题可能出现 courage→encourage。 4. wisdom n.智慧 → wise adj.明智的 【教材原句】She is full of courage and wisdom. (p.21) 补充例句：It was wise of Confucius to say that we should treat our elders with respect. (adapted from p.22) 词形转换：wise (adj.) → wisdom (n.) | 类似：free→freedom, king→kingdom 中考链接：wise→wisdom 词形转换在短文填空中有可能出现。It is wise of sb to do sth 是 Unit 2 语法重点。 5. brave adj.勇敢的 v.勇敢面对 【教材原句】It was very difficult for him to brave the cold weather and great heights. (p.23) 【教材原句】Amelia Earhart was always a brave child, full of courage. (p.25) 一词双词性 形容词：a brave soldier / a brave decision 动词：brave the storm / brave the cold（"勇敢面对"，初中生只需认识此动词用法，不要求会用） → 名词：bravery (n. 勇敢) 中考链接：brave 作形容词是基础词，动词用法在教材中出现但只要认识即可。写作中可替换 bold。 6. creative adj.有创造力的 → create v.创造 → creativity n.创造力 【教材原句】It was very creative of him to design it. (p.21) 词形转换链：create (v.) → creative (adj.) → creativity (n.) → creation (n.) → creator (n.) 中考链接：create/creative 在河北中考阅读中高频出现。词形转换题可能考查 create→creative。 7. curiosity n.好奇心 → curious adj.好奇的 【教材原句】He showed a deep love and curiosity for the things he studied. (p.23) 词形转换：curious (adj.) → curiosity (n.) | 类似：serious→seriousness? NO, 不规则变化，必须单独记。 常用搭配：out of curiosity（出于好奇）/ be curious about sth（对……好奇） 中考链接：curious→curiosity 是不规则名词变化，河北中考词形转换题可能出现。be curious about 是阅读高频短语。 8. pioneer n.先驱；先锋 【教材原句】（Zhang Qian was）the pioneer of the famous Silk Road. (p.22 Grammar Focus) 补充例句：Yuan Longping was a pioneer in farming research. / She was a pioneer of modern nursing. 常用搭配：a pioneer of/in... / pioneer work / a pioneer in the field of... 中考链接：pioneer 是课标词汇，阅读中识别即可，写作中可用于人物介绍（Unit 2 写作任务）。 9. spread v.传播；散布；蔓延 (spread-spread-spread) 【教材原句】the need for cleaner hospitals to stop the spread of diseases (p.20 Nightingale) 【教材原句】You'd better wear a mask... The disease is spreading... (p.25 Vocabulary exercise) 核心用法 及物：spread news / spread kindness / spread the message 不及物：The disease spreads quickly. / The news spread fast. → 过去式和过去分词都是 spread（不变化！中考陷阱考点） 中考链接：spread 的不规则变化（不变形）是河北中考短文填空的可能考点。spread-spread-spread 必须记牢。 第五部分 Unit 2 重点词汇（★★） 10. drop out (of) 辍学；退出；不再参加 【教材原句】He dropped out of school at an early age, but he continued to study... (p.19) 搭配：drop out of school / drop out of a race 教学提示：drop out of + n. 中考阅读中偶有出现，认识即可。 11. look up to 仰慕；钦佩 【教材原句】Who do you look up to? (p.21) 搭配：look up to sb = admire sb 教学提示：注意区别：look up（查阅）vs look up to（仰慕）——多一个to意思完全不同。 12. well-respected adj. 备受尊敬的 【教材原句】The well-respected biologist had spent his whole life...

(p.19) 搭配：make a discovery / scientific discoveries 教学提示：discover (v.发现) → discovery (n.) → discoverer (n.发现者)。注意：discover 指"发现已存在的事物"，invent 指"发明新事物"。 15. achievement n. 成就 → achieve v. 【教材原句】...match the people with their achievements. (p.20) 搭配：make an achievement / a sense of achievement / achieve one's dream 教学提示：achieve one's dream 是写作高频表达。achievement 可数。 16. profession n. 职业 → professional adj. 【教材原句】...match the people with their professions. (p.19) 搭配：the teaching profession / professional skills 教学提示：区别：job（具体工作）/ career（职业生涯）/ profession（需专业训练的职业如医生律师） 17. volunteer n. 志愿者 v. 自愿做 【教材原句】...volunteered as a nurse to help the wounded soldiers. (p.20) 搭配：volunteer to do sth / work as a volunteer 教学提示：作动词的用法（volunteer to do）是初中生需要掌握的。 第六部分 Unit 2 识记词汇速览（★） （一）职业/身份名词 — 后缀规律归纳 单词 释义 后缀 来源 教材出处 scientist n. 科学家 -ist science → scientist p.12/19 chemist n. 化学家 -ist chemistry → chemist p.12/19 physicist n. 物理学家 -ist physics → physicist p.12/19 biologist n. 生物学家 -ist biology → biologist p.16/25 historian n. 历史学家 -ian history → historian p.12/19 researcher n. 研究人员 -er research → researcher p.12/19 professor n. 教授 -or (独立词) p.12/19 engineer n. 工程师 -eer (独立词) p.20 inventor n. 发明家 -or invent → inventor p.19 thinker n. 思想家 -er think → thinker p.19/26 后缀教学建议 Unit 2 的 Vocabulary in Use (p.25) 专门练后缀 -ist/-er/-or/-ian。 建议让学生自己总结规律：-ist 多接学科名词（science→scientist），-er 多接动词（research→researcher），-ian 接特定名词（history→historian）。 不要死记，多举几个例子让学生找感觉。 （二）其他识记词汇 单词 词性/释义 常见搭配 出处 kindness n. 善良 show kindness to sb / kindness and care p.26 peace n. 和平 bring peace / live in peace p.26 disease n. 疾病 the spread of diseases / a serious disease p.13/20 wound n. 伤口 v. 使受伤 wounded soldiers / a deep wound p.20 calendar n. 日历 check my calendar / the Chinese calendar p.19/25 elder adj./n. 年长的；长辈 elder daughter / respect our elders p.22/25 wise adj. 明智的 It was wise of Confucius to say... p.22/25 radio n. 无线电；收音机 heard about...on the radio / radio engineering p.23/25 第七部分 Unit 2 易混词辨析 词/短语 含义 例句 备注 used to do 过去常常做（现在不了） He used to live in a small flat. 后接动词原形 be used to doing 习惯于做某事 He is used to living alone now. to 是介词，后接 doing be used to do 被用来做某事 The knife is used to cut bread. 被动语态，= be used for doing take place 发生（按计划/预期） The meeting will take place on Friday. 主语为事件，无被动 happen 发生（偶然/意外） The accident happened at midnight. 主语为事故/事情，无被动 bring about 引起；促成（宏观变化） The railway brought about great changes. 强调过程感，= lead to result in 导致（结果） Hard work results in success. 更强调最终结果 result from 由……引起（反向因果） Success results from hard work. 注意方向！A results from B = B causes A look up to 仰慕；钦佩 I look up to my father. = admire look up 查阅；向上看 Look up the word in the dictionary. 宾语为信息/资料 look after 照顾 She looks after her grandma. = take care of look forward to 期待 I look forward to your reply. to 是介词！+ doing wide adj. 宽的（具体） a wide road / a wide river 修饰具体事物宽度 widely adv. 广泛地（抽象） widely used / widely known 修饰动词或形容词 discover v. 发现（已存在的事物） discover a new planet → discovery (n.) invent v. 发明（新事物） invent a new machine → invention (n.) / inventor (n.) 第八部分 Unit 2 词形转换规律归纳 转换类型 示例 同类词 备注 adj. → n. wise → wisdom free → freedom, king → kingdom 不规则变化，逐个记 adj. → n. curious → curiosity serious → seriousness?
