Unit 2 Inspiring People Section A (4a-4c) 课件 2026-2027学年人教版九年级英语上册

该初中英语课件聚焦“It is/was + adj. + (of/for sb.) to do sth.”和强调句“It is/was...that...”两大核心句型，通过4a人物填空（如袁隆平、居里夫人事迹）导入，搭建从单句补全到句式改写再到语篇运用的学习支架，帮助学生系统掌握句型结构与用法。 其亮点在于融合文化意识与思维品质，依托张骞、孔子等中外榜样人物语料，引导学生在归纳对比of/for用法中培养逻辑思维，在语篇补全中辩证分析人物精神闪光点。采用“发现规律—专项练习—语篇运用”教学方法，提升学生语言运用能力和文化认同感，为教师提供清晰教学路径与丰富实例素材。

It was difficult for ... to do that kind of work back in those days. It's really very nice of ... to support and encourage ... It was great of Yuan Longping to develop a new kind of rice and help reduce hunger. It was amazing that Madame Curie did research in physics and chemistry even though she faced terrible living and working conditions. It was difficult for Zhang Qian to do that kind of work back in those days. It's really very nice of my head teacher to support and encourage us students when we meet study problems. It is/was ... (of/for sb. ) to do ... 英语高频基础句型，it 作形式主语，真正的主语是后面的 to do sth.，翻译为 “（某人）做某事是…… 的”。 一、基本结构与时态 1. 一般现在时：It is + 形容词 + (of/for sb.) + to do sth. 描述当下、常态、客观事实。 例：It is easy to learn English. 学英语很简单。 2. 一般过去时：It was + 形容词 + (of/for sb.) + to do sth. 描述过去发生的事。 例：It was kind of him to help me. 他当时帮我真是太好了。 二、of sb. 和 for sb. 的核心区别（重点） It is/was ... (of/for sb. ) to do ... 1. 用 of sb. 适用条件：形容词用来描述人的性格、品德、品质、情绪，可以直接改成：Sb. + be + 形容词 + to do sth. 常用形容词：kind（善良的）、nice（友善的）、good（好心的）、clever（聪明的）、foolish（愚蠢的）、silly（傻的）、brave（勇敢的）、polite（有礼貌的）、rude（粗鲁的）、careless（粗心的）、honest（诚实的）等。 例句：It is polite of you to greet others. = You are polite to greet others. It was foolish of her to give up. = She was foolish to give up. 2. 用 for sb. 适用条件：形容词用来描述事物的性质、难易、好坏、重要性，不评价人的品性， It is/was ... (of/for sb. ) to do ... 不能转换成上面的主谓结构。 常用形容词：easy（容易的）、difficult/hard（困难的）、important（重要的）、necessary（必要的）、useful（有用的）、dangerous（危险的）、interesting（有趣的）、boring（无聊的）、possible（可能的）、impossible（不可能的）等。 例句：It is difficult for me to finish the work. 对我来说，完成这项工作很难。 It is dangerous for kids to play with fire. 小孩子玩火很危险。 三、句式拓展与否定、疑问 1. 否定句：在 be 动词后加 not 例：It is not easy for him to swim. 对他来说游泳并不容易。 2. 一般疑问句：把 be 动词提前 It is/was ... (of/for sb. ) to do ... 例：Is it kind of her to help us? 她帮助我们，人是不是很好？ 3. 特殊疑问句：用 What/How 等提问 例：How hard is it for you to learn math? 对你来说学数学有多难？ 四、补充易错点 1. 句型中必须用不定式 to do，不能用 doing 或原形。 错误：It is good helping me. 正确：It is good of you to help me. 2. 当句中没有明确指出 “某人” 时，可直接省略 of/for sb. 例：It is wonderful to travel. 旅行很棒。 3. 多个动作并列时，后面的 to 可省略。 例：It is fun for us to read and write. 读写对我们来说很有趣。 用法拓展 一、搭配不同句式的变体 1. 搭配情态动词 在 be 动词前加 can/could/may/might/must/should 等情态动词，表达推测、建议、要求等含义，结构变为：It + 情态动词 + be + 形容词 + (of/for sb.) to do。 例：It must be careless of him to make so many mistakes. 例：It should be necessary for us to keep on exercising. 2. 时态拓展：将来时 表达未来的情况，常用 It will be + 形容词 + (of/for sb.) to do。 例：It will be great for you to join the club. 例：It will be wise of her to take the advice. 用法拓展 二、形容词的特殊使用情况 1. 同一形容词分场景用 of/for 部分形容词兼具评价人品和描述事物特征两种含义，搭配不同介词： good 表人品善良，用 of：It is good of you to wait for me. 你愿意等我，真好。 表事情有益，用 for：It is good for you to drink more water. 多喝水对你身体有益。 bad 表人品恶劣，用 of：It is bad of him to lie to his parents. 他对父母撒谎，品行不好。 表事情有害，用 for：It is bad for your eyes to read in the sun. 在阳光下看书伤眼睛。 2. 后置副词修饰形容词 用法拓展 可在形容词后加 too/quite/very/rather 等副词加强语气，结构不变。 例：It is very brave of the boy to save the cat. 这个男孩救下小猫，十分勇敢。 例：It is too hard for me to solve this problem. 这道题对我来说太难了。 三、深层句式转换 1. 与不定式复合结构互换 for sb. to do 本身就是不定式复合结构，可和部分同义句型转换。 原句：It is convenient for us to go by subway. 我们坐地铁出行很方便。 转换：To go by subway is convenient for us.（直接用不定式作主语，书面语中较常见） 2. 同义句替换 表 “做某事对某人来说很……”，可替换为 Sb. find/think it + 形容词 + to do 用法拓展 例：It is boring for me to stay at home alone. = I find it boring to stay at home alone. 描述人物品行的 of 句型，可直接改写为主人作主语的简单句（基础用法延伸） 例：It was generous of my uncle to help us. = My uncle was generous to help us. 四、否定形式的细分用法 1. 完全否定：be 后加 not，最常用 例：It is not polite of you to interrupt others. 打断别人说话是不礼貌的。 2. 部分否定 / 强调 “不必、不该”：搭配 not necessary / unnecessary 例：It is unnecessary for you to get up so early. 你没必要起这么早。 3. 否定不定式：在 to 前加 not，表 “不做某事是…… 的” 例：It is wise of you not to give up easily. 你不轻易放弃，很明智。 用法拓展 五、特殊主语与语境用法 1. 用于正式评价、评论语境（书面 / 口语通用） 常用来评价行为、发表看法，多用于作文、日常点评。 It was thoughtful of you to prepare gifts for everyone. 你贴心地为所有人准备了礼物。 2. 逻辑主语为不定代词 当逻辑主语不是具体人物，是everyone/anyone/no one等不定代词时，仍沿用原结构。 It is important for everyone to protect the environment. 保护环境对每个人都很重要。 六、高频易错点补充拓展 1. 句式中 it 只能作形式主语，不能换成 this/that。 错误：This is easy for me to finish. 正确：It is easy for me to finish. 用法拓展 2. 若不定式后接介词，介词不可省略（不定式短语为不及物结构，后面有逻辑宾语时）。 It is comfortable to live in this room. 住在这个房间里很舒适。（in 不能丢） 3. 主谓一致：无论后面的不定式内容是单数还是复数行为，句中 be 动词一律和形式主语 it 保持一致，只用 is/was。 It is interesting to read stories and poems. 读故事和诗歌很有趣。 4. 口语简化：日常对话中可省略逻辑主语，直接用 It is + 形容词 + to do，泛指大众情况。 It is fun to play games. 玩游戏很有趣。 It is/was ... that ... 这个句型主要分为强调句和主语从句两大类，结构外形相似但用法、含义、改写规则完全不同，下面分开讲解。 一、强调句型（最核心用法：It is/was + 被强调部分 + that/who + 其余部分） 1. 基本含义与作用 用来突出、强调句子中的主语、宾语、状语，翻译时常加上“正是、就是、恰恰”加强语气。句首的 it 无实际词义，只作形式引导词。 2. 时态规则 It is ... that ...：用于现在时、将来时，对应原句一般现在、现在进行、一般将来等时态。 It was ... that ...：用于过去时态，对应原句一般过去、过去进行、过去完成等时态。 It is/was ... that ... 3. 连接词选用 被强调部分是人：可用 that 或 who； 被强调部分是事物、时间、地点、原因、方式等：只能用 that，不能用when / where / because / how。 4. 可强调的句子成分 原句统一参照：He met Lily in the park yesterday.（他昨天在公园遇见了莉莉。） 强调主语 It was he that/who met Lily in the park yesterday. 正是他昨天在公园遇见了莉莉。 强调宾语 It was Lily that he met in the park yesterday. 他昨天在公园遇见的正是莉莉。 It is/was ... that ... 强调地点状语 It was in the park that he met Lily yesterday. 他昨天就是在公园里遇见莉莉的。 强调时间状语 It was yesterday that he met Lily in the park. 他就是昨天在公园遇见莉莉的。 5. 句式变形 否定强调：把否定词 not 放到被强调部分中 It was not Tom that broke the window. 打破窗户的不是汤姆。 一般疑问句：将 is/was 提前至句首 Was it in this shop that you bought the book? 你是在这家店里买的书吗？ 特殊疑问句：特殊疑问词 + is/was + it + that... It is/was ... that ... Where was it that you found your key? 你究竟是在哪里找到钥匙的？ 6. 关键判断技巧（区分强调句） 去掉 It is/was ... that，剩余部分语序微调后句子结构完整、语义通顺，就是强调句。 例：It was yesterday that we arrived. 去掉框架：We arrived yesterday. 句子完整，判定为强调句。 二、主语从句句型（It is/was + 名词 / 形容词 / 过去分词 + that 从句） 1. 结构本质 it 是形式主语，真正的主语是后面整个 that 引导的主语从句，翻译为 “…… 这件事是…… 的”。去掉 It is/was...that 后，句子无法独立成句，以此和强调句区分。 2. 细分搭配与例句 It is/was ... that ... （1）It is + 形容词 + that 从句 常用形容词：important, necessary, clear, obvious, strange, natural, true 等。 从句中常使用虚拟语气（表建议、要求、必要性）：从句谓语用 (should) + 动词原形，should 可省略。 It is important that we (should) keep honest. 我们保持诚信是很重要的。 It is strange that he (should) refuse the invitation. 他竟然拒绝了邀请，实在奇怪。 （2）It is + 名词 + that 从句 常用名词：a fact, a pity, a surprise, a rule, good news 等。 It is a pity that you missed the party. 你错过了派对，真是遗憾。 It is good news that our team won the game. 我们队伍赢了比赛，真是个好消息。 It is/was ... that ... （3）It is/was + 过去分词 + that 从句 常用过去分词：said, reported, known, believed, decided, suggested 等，多用来转述观点、消息、规定，译为 “据说、据报道、众所周知”。 It is said that he will move abroad. 据说他要移居国外。 It is well known that practice makes perfect. 众所周知，熟能生巧。 3. 时态用法 It is + ... + that 从句：描述客观事实、当下看法、常态； It was + ... + that 从句：描述过去的情况、当时的观点或已发生的事。 It was a surprise that she left so early. 她那么早就离开了，当时大家都很意外。 It is/was ... that ... 三、两大句型核心区分 1. 结构拆分不同 强调句：去掉 It is/was...that，句子完整通顺； 主语从句：去掉框架后，剩余部分成分残缺，不能独立成句。 2. 功能不同 强调句：用来加强语气，突出某一个句子成分； 主语从句：用来承载长主语，平衡句子结构，本身无强调含义。 3. 连接词限制 强调句强调人可用 who/that，其余一律用 that； 主语从句固定只用 that，that 只起连接作用，无词义、不充当句子成分。 It is/was ... that ... 四、高频易错点 1. 强调句中，强调时间、地点、原因状语时，严禁用 when/where/because，必须用 that。 错误：It was last week when I came back. 正确：It was last week that I came back. 2. 主语从句表 “建议、要求、必要” 时，牢记 (should) do 虚拟结构，不可用时态变化。 3. 两种句型中，that 都不能省略。 4. 强调句的主谓一致：被强调部分为单数 / 复数，不影响框架，be 动词始终和 it 保持一致，只用 is/was。 _________________________________________________________________________________________________________.
