【分析】
解题思路:先明确方框内单词的词义与词性,再分析每个句子的语法结构,判断空格所需词性,最后结合语境选择合适单词并按语法规则变形(如名词复数、形容词转换)。
【解析】
1. 句型“it is + adj + for sb to do sth”表示“对某人来说做某事是……的”,空格处需形容词,方框中necessary(必要的)符合语境,故填necessary。
2. 固定搭配“plant seeds of...”意为“播下……的种子”,seed是可数名词,此处表泛指需用复数,故填seeds。
3. 固定短语“during one's childhood”意为“在某人的童年时期”,childhood符合语境,无需变形,故填childhood。
4. 形容词faraway后接名词,region是可数名词,此处指多个遥远地区需用复数,故填regions。
5. 空格修饰名词country,需用形容词,west的形容词形式为western(西方的),符合语境,故填western。
【答案】
1. necessary
2. seeds
3. childhood
4. regions
5. western
【知识点】
形容词用法;名词的数;固定搭配

【分析】
这几道题均考查it作形式主语的句型,核心思路是用it代替后面真正的主语(that从句或不定式),避免句子头重脚轻。解题时需注意两点:一是判断句型结构(It + be + adj + that从句/It + be + adj + (for/of) sb to do);二是区分形容词后用for还是of:若形容词修饰人的品质,用of;若修饰事物的性质,用for。
【解析】
1. 句型为It + be + adj + that从句,描述过去的动作,be动词用was;“勇敢的”是brave,“令人钦佩的”是admirable,故填It; was; brave; admirable。
2. 句型为It + be + adj + that从句,“令人惊讶的”是amazing,过去式用was,故填It; was; amazing; that。
3. 句型为It + be + adj + of sb to do,kind修饰人的品质,用of,故填It's; of; you。
4. 句型为It + be + adj + of sb to do,wise修饰人的品质,用of,故填It's; wise; of; him。
5. 句型为It + be + adj + for sb to do,necessary修饰做某事的必要性,用for,故填It's; necessary; for; us。
【答案】
1. It; was; brave; admirable
2. It; was; amazing; that
3. It's; of; you
4. It's; wise; of; him
5. It's; necessary; for; us
【知识点】
it作形式主语;形容词搭配;主语从句
【点评】
本题围绕it作形式主语的核心句型展开,是初中英语的基础考点,重点考查学生对of/for在形容词后用法的区分,属于必须掌握的基础知识点。

5. It was inspiring that she won the competition.

解析

【分析】
本题考查it作形式主语的用法,核心是将真正的主语(不定式或that从句)后置,避免句子头重脚轻。需分两种情况处理:①若真正主语是不定式,结构为It + be + 形容词 + (for/of sb) + to do sth,其中形容词描述人的品质时用of,描述事物性质时用for;②若真正主语是that引导的从句,结构为It + be + 形容词 + that从句。需根据每个句子的真正主语类型和形容词属性改写。
【解析】
1. 原句真正主语是不定式To learn English well,形容词important描述事物,故改写为It is important to learn English well。
2. 原句中that指代前面的完整句子(从句),形容词amazing修饰从句内容,故改写为It was amazing that he finished the task on time。
3. 形容词kind描述人的品质(you的品质),真正主语是不定式to help the old man cross the road,故改写为It was kind of you to help the old man cross the road。
4. 形容词necessary描述事物,真正主语是不定式to protect the environment,逻辑主语是us,故改写为It is necessary for us to protect the environment。
5. 原句中that指代前面的完整句子(从句),形容词inspiring修饰从句内容,故改写为It was inspiring that she won the competition。
【答案】
1. It is important to learn English well.
2. It was amazing that he finished the task on time.
3. It was kind of you to help the old man cross the road.
4. It is necessary for us to protect the environment.
5. It was inspiring that she won the competition.
【知识点】
it作形式主语;不定式作主语;of/for的用法
【点评】
本题聚焦it作形式主语的基础语法,需区分不定式作主语和that从句作主语的结构,以及of与for的使用差异,是英语语法的核心考点,适合巩固基础。
