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. [新素材] It’s possible scientists to complete research projects quickly by using DeepSeek.
5. [2026 浙江金华期中改编 ]It’s very dangerous us to talk on the phone while crossing the road.

1. of 2. that 3. of 4. for 5. for

【分析】首先明确It作形式主语的三类核心结构：① 若形容词修饰人的品质（如brave、wise等），用结构“It is + adj. + of sb. to do sth.”；② 若形容词修饰做某事的性质（如possible、dangerous等），用结构“It is + adj. + for sb. to do sth.”；③ 若真正主语是完整句子，用结构“It is + adj. + that从句”。再结合每句语境判断：第1题形容词brave描述人的品质，第3题形容词wise描述人的品质，故用of；第2题后接完整句子作主语，故用that；第4题possible、第5题dangerous均描述做某事的性质，故用for。
【解析】1. 形容词brave修饰人的品质，对应结构“It is + adj. + of sb. to do sth.”，故填of；2. 空格后为完整句子作真正主语，需用that引导主语从句，故填that；3. 形容词wise修饰人的品质，对应结构“It is + adj. + of sb. to do sth.”，故填of；4. 形容词possible描述做研究的性质，对应结构“It is + adj. + for sb. to do sth.”，故填for；5. 形容词dangerous描述过马路打电话的性质，对应结构“It is + adj. + for sb. to do sth.”，故填for。
【答案】1. of 2. that 3. of 4. for 5. for
【知识点】It作形式主语的固定句式；介词for/of的用法；that引导主语从句
【点评】本题考查初中英语核心基础句式，需区分It作形式主语时，of/for接不定式与that接从句的不同用法，属于易掌握的基础题。
【难度系数】0.6

二、根据汉语提示补全句子或翻译句子
1. 人们在缺水的沙漠里种树是很难的。

3. It is amazing that 4. It is interesting for
5. It's very necessary for teenagers to pour out their troubles to their parents.

【分析】
这几道题主要考查英语中“It’s + 形容词 + for sb. to do sth.”和“It’s + 形容词 + that从句”的核心固定句型。解题时，需先判断句子后续结构：若接动词不定式短语，使用前者句型；若接完整句子，使用后者句型。再结合汉语提示、已给出的英文内容，补全或翻译对应的正确表达，同时注意时态（如第2题的过去式）和固定搭配的准确性。
【解析】
1. 考查句型“It’s + adj + for sb to do sth”，“种树”对应plant trees，故填for; to plant trees。
2. 时间状语“ten years ago”表明用一般过去时，“不可能的”对应impossible，结合句型为It was impossible for him。
3. 后续是完整句子，需用“It’s + adj + that从句”结构，“神奇的”对应amazing，故填It is amazing that。
4. 考查句型“It’s + adj + for sb to do sth”，“有趣的”对应interesting，故填It is interesting for。
5. 汉译英需用指定句型和短语，“对青少年来说”对应for teenagers，“向父母倾诉烦恼”对应pour out their troubles to their parents，结合句型为It's very necessary for teenagers to pour out their troubles to their parents。
【答案】
1. for; to plant trees 2. It was impossible for him 3. It is amazing that 4. It is interesting for 5. It's very necessary for teenagers to pour out their troubles to their parents.
