重点语法:it的固定句型精讲练50题
语法知识精讲
一、it 的基础用法(简单回顾)
1.指代事物、动物、未知身份的人
It is a dog. 它是一条狗。
—Who is knocking at the door? —It’s me. — 谁在敲门?— 是我。
2.指代时间、天气、距离
It’s 7 o’clock. 七点了。
It’s rainy today. 今天下雨。
It’s 5 kilometres from my home to school. 从我家到学校 5 公里。
九年级重点:it 作形式主语、形式宾语(中考高频)
二、it 作形式主语【必考句型】
真正的主语是后面的to do /doing/ 从句,it 只是占位,无实际含义。
✅ 结构:It+be+形容词 / 名词+to do sth. 做某事是……(最核心!)
1. It is+adj.+for sb. to do sth.
形容词描述这件事的性质(difficult, easy, important, necessary, possible, hard)
翻译:对某人来说,做某事是……
•It is important for us to learn English. 对我们来说学英语很重要。
2. It is+adj.+of sb. to do sth.
形容词用来形容人的品质(kind, nice, clever, foolish, careless, polite)
翻译:某人做某事,真是……
•It’s kind of you to help me. 你帮助我,真好。
✨判断口诀:形容词能修饰人,用 of;修饰事情,用 for。
检验:You are kind ✔ → of;To learn English is important ✔ → for
3. It’s+n.+to do sth. 做某事是一件…… 事
•It’s a good idea to take notes. 记笔记是个好主意。
4. It is no use /no good doing sth. 做某事没用(了解)
It’s no use crying over spilt milk. 覆水难收。
5. It seems that… 似乎 / 好像……(九年级重点)
It seems that he is right. 似乎他是对的。
= He seems to be right.
6. It happens that… 碰巧……
It happened that I met him. 我碰巧遇见了他。
7. It is said that… 据说……;It is reported that… 据报道……
It is said that the story is true. 据说这个故事是真的。
三、it 作形式宾语【九年级难点,单选+完形】
✅ 结构:主语+find/think/believe+it+adj.+to do sth.
it 代替后面 to do,作动词 find/think 的宾语;形容词作宾补。
翻译:某人发现 / 认为做某事是……
•I find it difficult to learn math well.
我发现学好数学很难。
同类动词:find, think, feel, consider
四、强调句型:It is/was+被强调部分+that/who…(九上,中考阅读常出现)
用来强调句子的主语、宾语、状语;去掉 It is…that,句子仍然完整。
•It was Tom that helped me. 是 Tom 帮助了我。(强调人可用 who)
•It is at 6:00 that we will meet. 我们是在六点见面。
注意:不能强调谓语动词
五、it 的其他高频固定句型
1.It takes sb.+时间段+to do sth. 花费某人多长时间做某事(超级必考)

语法知识精练
1.It was selfless ________ Yuan Longping ________ develop a new kind of rice and help reduce hunger.
A.for; to B.of; to C.of; for D.for; of
【答案】B
【详解】句意:袁隆平培育出一种新型水稻并帮助减少饥饿,他是无私的。
固定句型It is+adj.+of/for+sb.+to do sth.中,当形容词表示人的性格、品质(如selfless无私的)时,介词用of;当形容词表示事物的性质时,介词用for。本句中selfless修饰人的品质,故第一空填of;不定式作真正的主语,故第二空填to。
2.It was very difficult ________ him ________ brave the cold weather and great heights in Xizang.
A.of; to B.for; to C.for; for D.of; for
【答案】B
【详解】句意:他要直面西藏的严寒与高海拔,这对他来说十分艰难。
of……的;for为了;to到/不定式符号。固定句型“It is+adj.+for/of sb.+to do sth.”,当句型里的形容词是用来描述“事情的属性”(比如本句的difficult,困难是“在西藏直面严寒和高海拔”这件事的特点),就用for;如果形容词是用来描述人的性格品质(比如kind、nice)才用of,所以这里第一空选for;第二空动词不定式作真正的主语,应用to。
3.It is always important ________ everyone ________ keep going in life.
A.of; to B.for; to C.for; for D.of; for
【答案】B
【详解】句意:对每个人来说,在生活中坚持总是很重要的。
固定句型“It is+adj+for/of sb+to do sth”,当形容词表示事物的性质(如 important, necessary)时,介词用for;当形容词表示人的性格特征(如 kind, clever)时,介词用of。本句中important表示事情的重要性,故第一空填for;第二空动词不定式作真正的主语,填to。
4.It was kind ________ our teachers ________ support and encourage us.
A.for; to B.of; to C.of; for D.for; of
【答案】B
【详解】句意:我们的老师支持并鼓励我们,真是太好了。
for为了;of……的;to到,向。根据句型“It is+adj.+of/for sb.+to do sth.”可知,此处考查不定式复合结构。当形容词表示人的品质或性格特点时,用of sb.,如kind、nice、careful等;当形容词表示事情的性质时,用for sb.。本句中kind表示“老师的善良”,是对人的评价,因此第一空用of;第二空表示“支持并鼓励我们”这一动作,用动词不定式to support and encourage。故填of; to。
5.________ amazing that Tu Youyou kept studying herbs for decades.
A.This is B.That’s C.It’s D.Its

【详解】句意:屠呦呦坚持研究草药几十年,这真是令人惊叹。
This is这是;That’s那是;It’s它是(it作形式主语);Its它的(所有格)。固定句型“It’s+形容词+that从句”,其中It作形式主语,真正的主语是后面that引导的从句。This is和That’s不用于此句型;Its为物主代词,不能作主语。

A.of; to B.for; to C.of; / D.for; /
【答案】B
【详解】句意:对于古代人来说,去西域旅行是困难的。

8.It is always important ________ to keep going in life.
A.of us B.for us C.to us D.with us
【答案】B
【详解】句意:对我们来说,在生活中不断前行总是很重要的。
根据“It is+adj./of+for sb.+to do sth.”这一固定句型可知,当形容词描述事物的属性时,用介词for,当形容词描述人的性格品质时,用of,此处形容词important是用来描述“坚持前行”这件事的属性,要搭配介词for。

A.telling jokes to; for B.playing jokes on, for
C.making jokes about; of D.joking; of
【答案】B
【详解】句意:——我的同桌露西喜欢开她同学的玩笑。——那是不礼貌的!同学尊重老师是很重要的。
考查动词短语以及介词辨析。tell jokes to跟某人讲笑话;play jokes on开某人玩笑;make jokes about开某人玩笑;joke开玩笑。根据“That’s rude”可知,开别人玩笑是粗鲁的,排除A选项。固定句式:It is+形容词+of/for sb to do sth“某人做某事是……的”,形容词修饰人,介词用of,形容词修饰物,介词用for。important是修饰物的形容词,所以第二空填for,故选B。
48.It’s not ________ him to help these children with intellectual disabilities because he has received little training so far.
A.simple for B.simple of C.hard for D.hard of
【答案】A
【详解】句意:对他来说,帮助这些智力残疾的孩子并不简单,因为到目前为止,他几乎没有接受过培训。
考查固定句型和形容词辨析。simple 简单的,容易的;hard困难的。 It’s adj. for sb. to do sth. 表示做某事对某人来说很……,这里的形容词表示做某事的属性;It is+adj.+of sb. +to do sth.表示某人这么做真是太……了,这个形容词是用来形容人的,形容词通常是表示人的性格特点和品质方面的词。此句中simple或hard是表示做某事的属性,用for,排除B和D。由“because he has received little training so far.”可知帮助这些智力残疾的孩子是困难的,由“not”可知simple符合题意,故选A。
49.It is better to ask someone for advice than ________ something.
A.risk doing B.risk to do C.to risk doing D.to risk to do
【答案】C
【详解】句意:向人征求建议比冒险去做一些事更好。
考查It固定句型和非谓语。“冒险做某事”用“risk doing sth”来表示,动名词作宾语,排除B和D;“做某事比做某事更好”用“It’s better to do sth than to do sth”句型来表示,其中动词不定式作同类比较。故选C。
50.It’s dangerous ________ the road here. There’s ________ traffic.
A.to cross; much too B.to cross; too much C.across; too much D.across; much too
【答案】B
【详解】句意:在这里过马路很危险。交通太拥挤了。
考查非谓语动词以及too much和much too的用法。cross“穿过”,动词;across“穿越”,介词。“It’s+形容词+to do sth.”是固定结构,意为“做某事是……的”,则C、D两项错误;too much意为“太多的……”,用于修饰不可数名词;much too意为“非常,太”,用于修饰形容词或副词。traffic为不可数名词,所以用too much修饰。故选B。
