第三课时 Grammar Focus 4a — 4c 基础闯关 课后巩固·A级 Ⅰ．改写句子。 【1题答案】 【答案】good for our health to get up early 【解析】 【详解】句意：早起对我们的健康有益。原句是动词不定式To get up early作主语的句式，转换为it作形式主语的固定句型“It is+形容词/短语+to do sth”，其中it代替真正主语动词不定式放到句首，原句剩余的表语good for our health保留在is后，真正主语to get up early置于句末。 【2题答案】 【答案】clever of the boy to answer the question 【解析】 【详解】句意：这个男孩很聪明，能回答这个问题。原句是“so ... that + 结果状语从句”结构，转换为“It is + 形容词 + of sb to do sth”固定句型，意为“某人做某事是……”，形容词clever用来描述人的品质，介词用of，对应人物the boy，后面接真正的不定式主语to answer the question。 【3题答案】 【答案】brave enough of her to go into the dark house alone 【解析】 【详解】句意：她足够勇敢，独自走进那栋漆黑的房子。原句中“She was brave enough to do sth.”是强调某人具备某种品质去做某事，其同义表达为“It was + 形容词 + of sb. to do sth.”，形容词brave是用来修饰人的品质性格的，因此介词要用of，原句主语She在介词of后需变为宾格her。 【4题答案】 【答案】hard for me to remember all these new words in an hour 【解析】 【详解】句意：在一小时内记住所有这些新单词对我来说很难。原句是动词不定式To remember all these new words in an hour作主语的句式，转换为it作形式主语的固定句型It is +形容词+ for sb + to do sth，it替代真正主语不定式置于句首，形容词hard、对象for me保留在is之后，真正的动词不定式to remember all these new words in an hour放在句末。 【5题答案】 【答案】so careless of you to leave the door open 【解析】 【详解】句意：你太粗心了，没把门关好。将“You were + 形容词 + to do”结构转换为it作形式主语的固定句型It was + 形容词 + of sb to do，careless是描述人性格品质的形容词，搭配介词of，后半部分不定式to leave the door open保持不变，it无实义，仅用来后置真正主语。 【6题答案】 【答案】Leo wasn’t hurt badly 【解析】 【详解】句意：利奥很幸运，没有受重伤。将“主语 + be + 形容词 + not to do”结构转换为it作形式主语、that引导真正主语从句的句型，that后需要接完整陈述语序的句子；原不定式not to be hurt badly转化为从句Leo wasn’t hurt badly，时态保持一般过去时，副词badly位置不变，连接词that只起连接作用，无实际含义。 【7题答案】 【答案】we should protect the environment 【解析】 【详解】句意：对我们来说保护环境十分重要。原句是It is+形容词+for sb to do sth的固定句型，转换为It is+形容词+that从句结构时，that从句主语对应原句的宾格us改为主格we，从句谓语可搭配情态动词should后接动词原形protect，剩余宾语the environment保留不变。 【8题答案】 【答案】foolish of him to believe that lie 【解析】 【详解】句意：他太愚蠢了，竟然相信那个谎言。原句是“so ... that + 结果状语从句”，转换为“It is + adj. + of sb + to do sth”固定句型；形容词foolish用于描述人的性格品质，介词搭配of，原句主语he转换为宾格him，后面接真正的不定式主语to believe that lie。 Ⅱ． 【9~13题答案】 【答案】9. necessary 10. seeds 11. childhood 12. Western 13. came true 【解析】 【9题详解】 句意：如果我们想要进步，每天练习英语对我们来说是必要的。本句为固定句型It is + adj. + for sb. + to do sth.，意为“对某人来说，做某事是……的。”空处需要填入形容词作表语，备选词necessary是形容词，意为“必要的”，符合坚持练习英语才能提升的语境。 【10题详解】 句意：春天，我们买了一些花籽并种在了花园里。空前限定词some后要接可数名词复数，后文planted them表示复数指代，备选词seed是名词，意为“种子”，复数形式为seeds，契合种花播种的场景。 【11题详解】 句意：妈妈经常给我讲她在乡下快乐的童年往事。空处被形容词happy修饰，需要填入名词，结合语境表达的是“妈妈的乡村童年经历”应用child的派生名词childhood“童年”。 【12题详解】 句意：比起米饭和面条，我姐姐更喜欢披萨、汉堡这类西方食物。空处修饰名词food，需要填入形容词，备选词western作形容词意为“西方的”，Western food为固定搭配“西方食物”，此处表文化概念，Western首字母需大写。 【13题详解】 句意：经过多年努力，他成为医生的梦想终于实现了。句子主语his dream，结合“多年努力后达成心愿”的语境，句子时态为一般过去时，come true意为“实现”，符合语境，come的过去式为came。 能力提升 课后巩固·B级 Ⅲ． 【14~18题答案】 【答案】14. B 15. C 16. A 17. F 18. D 【解析】 【导语】本文是一篇人物说明文，介绍孔子的生平出身、核心思想、教育理念、著作以及他在中国历史与文化中的重要地位。 【14题详解】 前文介绍孔子的出生时间、姓名与出身争议，B项“Later, he became a great teacher at that time.”承接上文生平介绍，过渡到他后来成为伟大教育家的内容，衔接自然。 【15题详解】 前文提出孔子的思想以自律观念为基础，C项“He believed that a leader needed to exercise self-discipline.”具体阐释他关于自律的观点，对应前文self-discipline，逻辑通顺。 【16题详解】 后文介绍孔子撰写《春秋》、弟子整理《论语》等著作相关内容，A项“Confucius was famous for writing.”总领本段，点明孔子因著作闻名，引出下文各类典籍介绍。 【17题详解】 前文提到弟子根据孔子言论写成《论语》，F项“It teaches everyone in China how to behave well and be a good person.”中的It指代《论语》，说明这本书的教化作用，承接上文。 【18题详解】 前文说明如今孔子被公认为中国历史上最伟大的教育家之一，D项“He is also an important symbol of ancient Chinese culture.”递进补充他也是中国古文化重要象征，收束全文。 第1页/共1页 学科网（北京）股份有限公司 $ 第三课时 Grammar Focus 4a — 4c 基础闯关 课后巩固·A级 Ⅰ．改写句子。 1.
