“It is/was... (of/for sb.) to do sth.” 句型
一、含义：句型“It is/was ... (of/for sb.) to do sth.”表示“（某人/对某人来说）做某事是……的”，其中It作形式主语，后面的动词不定式to do sth.是句子真正的主语。
e.g. It is interesting for me to go swimming. 对我来说游泳是有趣的。
二、句型“It is/was ... (of/for sb.) to do sth.”中of和for的区别

注意：“It is/was ... of sb. to do sth.”句型一般可以转换成一个以of的宾语为主语的句子。
e.g. It is wise of them to do so. = They are wise to do so. 他们这样做是明智的。
“It is/was + adj. + that...”句型
“It is/was + adj. + that ... ”句型中，It作形式主语，真正的主语是that引导的主语从句，形容词用于对“that从句所描述的情况”进行评价。常用的形容词有 amazing, interesting, wonderful, inspiring, necessary, important等。
e.g. we study hard. 我们努力学习是重要的。
注意：这个句型里，that引导的主语从句不缺成分，that在从句中无实际意义，只起连接作用。

It is important that

【分析】
本题考查“It is/was + adj. + that...”句型的用法，该句型中it是形式主语，真正的主语是that引导的从句，形容词用于评价从句描述的情况。题目要表达“我们努力学习是重要的”，形容词为important，需填入符合该句型结构的开头部分，结合句意即可得出答案。
【解析】
根据“It is/was + adj. + that...”句型结构，结合句意“我们努力学习是重要的”，形容词为important，因此填入It is important that，构成完整句子：It is important that we study hard.
【答案】
It is important that
【知识点】
形式主语it；主语从句；形容词用法
【点评】
本题考查it作形式主语的两类核心句型，需区分“of/for sb. to do sth.”与“that引导主语从句”的用法，掌握形容词后接不同结构的规则，属于基础语法应用题目。

0.6

一、根据句意，用for，of或that填空
1. It was brave him to go to the lonely island alone.
2. It is inspiring Marie Curie won two Nobel Prizes in different fields.
3. It is not wise a student to waste too much time playing video games.
4. It's possible scientists to complete research projects quickly by using DeepSeek.

1. of 2. that 3. of/for 4. for

【分析】本题考查It is + adj + for/of/that的固定句型用法，需明确不同结构的使用规则：①当形容词描述人的品质、性格（如brave、wise），且后接“sb to do sth”时，用of；②当形容词描述事物属性，或后接“sb to do sth”时，用for；③当后接完整从句时，用that。据此逐个分析句子即可得出答案。
【解析】1. 句中形容词brave描述人的勇敢品质，符合“It is + adj + of sb to do sth”结构，故填of；2. 句中It为形式主语，真正主语是后面的完整从句，需用that引导主语从句，故填that；3. 形容词wise既可以描述人的明智品质，也可表示“对学生来说明智”，两种结构均成立，故填of/for；4. 形容词possible表示“做某事是可能的”，符合“It is + adj + for sb to do sth”结构，故填for。
【答案】1. of 2. that 3. of/for 4. for
【知识点】固定句型用法、介词辨析、连词用法
【点评】本题是初中英语基础考点，考查It引导的主语从句及for/of的用法，区分度适中，需牢记不同结构的使用场景。

二、按要求完成句子，每空一词
5. To do the work well is important.（改为同义句）
important the work well.
6. Writing a good book is difficult.（改为同义句）
It’s difficult a good book.
7. This idea seems to make sense.（改为同义句）

8. The volunteers are helpful. They show the visitors how to get to the gym.（合并成一句）
It’s the volunteers to show the visitors how to get to the gym.

5. It's; to do 6. to write 7. It seems that; makes 8. helpful of

【分析】本题为英语同义句转换题，需掌握常见的同义句式结构：1. 不定式/动名词作主语时，常用it作形式主语，结构为It's + adj + to do sth；2. seem to do sth可转换为It seems that + 从句；3. It's + adj + of/for sb to do sth结构中，形容词修饰人时用of，修饰事时用for。解题时需根据原句结构匹配对应同义句式，确保每空一词。
【解析】
5. 原句是不定式短语To do the work well作主语，同义句用it作形式主语，结构为It's + important + to do sth，故填It's; to do。
6. 原句是动名词短语Writing a good book作主语，同义句用It's + difficult + to do sth，故填to write。
7. 原句是seem to do结构，同义句转换为It seems that + 从句，原句时态为一般现在时，主语this idea是第三人称单数，从句谓语动词用makes，故填It seems that; makes。
8. 合并句考查It's + adj + of sb to do sth结构，此处形容词helpful修饰volunteers的品质，用介词of，故填helpful of。
【答案】5. It's; to do 6. to write 7. It seems that; makes 8. helpful of
【知识点】同义句转换、it作形式主语、seem的用法
【点评】本题聚焦初中英语基础同义句转换考点，涵盖it作形式主语替代非谓语作主语、seem的同义句式及形容词与介词的搭配，是学生需熟练掌握的核心句式，难度不大。
