主题
It is/was + adj. + (of/for sb.) to do sth. 与 It is/was … that … 强调句;necessary / come true / elder 等词汇;用目标句型评价榜样人物
教学重难点
重点
掌握 It is/was + adj. + (of/for sb.) to do sth. 结构,能区分 of(评价人的品质)与 for(描述事情特征);
掌握 It is/was … that … 强调句的基本变换规则;
能依托 4a、4b、4c 练习完成单句补全、句式改写与语篇填空。
难点
在复杂语境下精准区分 of 和 for,规避形容词判断失误;
灵活运用强调句对句子信息进行合理强调改写;
在连贯语篇中自然融合两类目标句型,让语法服务于真实的人物评价。
(一)4a:用名人事例补全评价句(课本 p.14)
用著名人物(或你认识的人)补全下列句子,体会评价句型。
图 1 4a 用名人事例补全 It 评价句
原句
句型要点
It was great of Yuan Longping to develop a new kind of rice and help reduce hunger.
of + 评价人的品质(great)
It was amazing that Madame Curie did research in physics and chemistry even though …
that 从句承载事迹
It was difficult for Zhang Qian to do that kind of work back in those days.
for + 描述事情特征(difficult)
It's really very nice of my head teacher to support and encourage us students …
of + nice 评价人品
【知识点】it 是形式主语,真正的主语是后面的 to do 或不定式复合结构;评价人的品质用 of,描述事情难易/重要性用 for。
(二)语法一:It is/was + adj. + (of/for sb.) to do sth.(课本 p.14)
归纳基本结构、of 与 for 的核心区别及常见易错点。
图 2 of sb. 与 for sb. 的核心区别
① 基本结构:It is + adj. + (of/for sb.) + to do sth.(一般现在/常态);It was + adj. + (of/for sb.) + to do sth.(过去)。
② 用 of sb.:形容词描述人的性格、品德、品质、情绪,可改写为 Sb. + be + adj. + to do。如 It is polite of you to greet others. = You are polite to greet others.
③ 用 for sb.:形容词描述事物的性质、难易、利弊、重要性,不能改写为主谓结构。如 It is difficult for me to finish the work.
④ of 常用形容词:kind, nice, good, clever, brave, polite, honest, foolish …;for 常用:easy, difficult, important, necessary, useful, dangerous …
【易混点】句型中必须用不定式 to do,不能用 doing 或动词原形;未明确“某人”时可省略 of/for sb.(如 It is wonderful to travel.);多个动作并列时后一 to 可省。
(三)语法二:It is/was … that … 强调句(课本 p.14–15)
学习强调句的构成、连接词选用与判断技巧。
图 3 强调句可强调的句子成分(主语/宾语/状语)
① 结构:It is/was + 被强调部分 + that/who + 其余部分。句首 it 无实义,仅作引导词。
② 时态:现在/将来相关用 It is … that …;过去相关用 It was … that …。
③ 连接词:被强调部分是人可用 that 或 who;是事物、时间、地点、原因、方式等一律用 that,不能用 when/where/because/how。
④ 判断技巧:去掉 It is/was … that …,剩余部分语序微调后句子完整通顺,即为强调句。
⑤ 例句:It was yesterday that he met Lily in the park. → He met Lily in the park yesterday.(完整,是强调句)
【提示框】强调时间/地点/原因状语时严禁用 when/where/because,必须用 that;被强调部分单复数不影响框架,be 动词始终与 it 一致(is/was)。
(四)4b:用括号词语改写句子(课本 p.15)
根据括号中的提示词,用目标句型改写句子。
图 4 4b 句式改写练习
题号
改写结果
1
It is necessary for us to listen to our teacher's advice.
2
It is amazing that tall trees can grow from tiny seeds.
3
It was wise of Confucius to say that we should treat elders with respect.
4
It was inspiring that Professor Gui's childhood dream of becoming a space scientist came true through his efforts.
5
It was brave of Victor Hugo to stand up for the common people he cared about.
(五)4c:语篇补全——张骞的故事(课本 p.15)
用正确的句子部件补全短文,体会句型在语篇中的运用。
选项:A. It is important for us B. It was really brave and admirable C. It is always inspiring D. It seemed impossible for him
第一空(描述读伟人故事的意义)→ C;第二空(被俘后完成任务似乎不可能)→ D;
第三空(他从未忘记使命,令人敬佩)→ B;第四空(了解过去、建设未来对我们重要)→ A。答案:C D / B A。
【过渡语】先判断空格在句中充当什么成分(主语评价/事情评价),再决定 of 还是 for;张骞事迹体现 perseverance(毅力)与 responsibility(责任感)。
(六)Think and Share:张骞为何鼓舞人心(课本 p.15)
列举两点张骞鼓舞人心之处并给出理由。
图 5 Think and Share:评价张骞的精神品质
① He had great perseverance. It seemed impossible for him to finish his task after being caught by the enemy, but he kept trying and succeeded about 10 years later.
② He was responsible and loyal. Even after many difficulties, he never forgot his task and brought back valuable information about the Western Regions for his country.
(七)改错训练(课本 p.15)
找出并改正下列句子中的错误,巩固句型规则。
图 6 句型改错练习
原句(误)
改正
It is brave for her to walk in space.
It is brave of her to walk in space.
It was very kind of him help me …
It was very kind of him to help me …
It is important of us to learn English well.
It is important for us to learn English well.
It was difficult for him finish the task …
It was difficult for him to finish the task …
It was in the park where we met …
It was in the park that we met …
【易混点】评价人的品质(brave/kind/important 表人品)用 of,描述事情(important 表重要性/难)用 for;to do 不可省;强调地点状语用 that 不用 where。
(八)核心词汇(课本 p.15)
本课时重点词汇(含音标、词性、释义与辨析)。
necessary /ˈnesəsəri/ adj. 必需的;必要的。It is necessary (for sb.) to do sth.;if necessary 如果有必要。
come true (梦想等)实现,成真。主语通常是 dream/wish/plan(事物),无被动;make one's dream come true 使梦想成真。
elder /ˈeldə(r)/ adj. 年长的;n. 长辈。elder brother/sister;respect the elders 尊敬长辈。
句型:It is/was + adj. + (of/for sb.) to do sth. / It is/was … that …(强调句)
【易混点】necessary 不能用人作主语(× Sb. is necessary to do),必须用 It is necessary for sb. to do;come true(事物作主语)vs. realize/achieve(人作主语);elder 表长幼辈分、作定语,不用于比较级(× elder than → older than)。
易错提醒
① It is/was … to do 中必须用不定式 to do,不可用 doing 或原形。
② of 与 for 的选用看形容词:评价人的品质(kind/brave/nice)→ of;描述事情特征(difficult/important/necessary)→ for。
③ 强调句中,强调时间、地点、原因状语时用 that,绝不用 when/where/because/how。
④ come true 无被动,主语是 dream 等事物;人作主语用 realize / achieve one's dream。
答题技巧
① 改写题先判断提示词是形容词还是名词:形容词用 of/for 句型,名词(dream/truth)用 that 从句。
② 区分强调句:去掉 It is/was … that … 后句子完整通顺即为强调句;否则可能是主语从句。
③ 语篇补全:看空格在句中作用(评价人物用 of,评价事情用 for),再结合上下文逻辑选句。
④ 改错题重点查:to do 是否遗漏、of/for 是否用错、强调句连接词是否误用 where/when。
语言点归纳
● 评价句型:It is/was + adj. + (of 表人品 / for 表事特征) + (sb.) + to do sth.
● 强调句型:It is/was + 被强调部分 + that/who + 其余;去掉框架句子仍完整即强调句。
● of 形容词:kind, nice, brave, polite, honest, wise, foolish …
● for 形容词:easy, difficult, important, necessary, useful, dangerous, amazing …
课堂总结
本课时系统学习了评价人物的两大核心句型:It is/was + adj. + (of/for sb.) to do sth. 与 It is/was … that … 强调句;
通过 4a 补全、4b 改写、4c 张骞语篇与改错训练,掌握了 of/for 的区分、强调句变换与常见易错点;
结合 necessary / come true / elder 等词汇,能够用规范语法在语篇中自然评价榜样人物的事迹与精神。
