真题一:单项选择(t作形式主语)
(2024北京海淀期中,北师大版)
_is important for us to learn English well.
A.This
B.That
C.It
D.What
答案:C
核心知识点:
it作形式主语,代替后面的不定式短语(to learn English well),避免句子头重脚轻,结构为“It+
be+形容词+for sb.+to do sth.”。
解析:空格处需用形式主语it指代真正主语“to learn English well'”,其他选项无此用法,故选C。
真题二:单项选择(t作形式宾语)
(2023陕西西安月考,北师大版)
I findeasy to finish the homework on time.
A.this
B.that
C.it
D.them
答案:C
核心知识点:
it作形式宾语,代替后面的不定式短语(to finish the homework),常用结构为“主语+谓语动词
(find/think/feel等)+it+形容词+to do sth.”。
解析:谓语动词find后需用it作形式宾语,真正宾语是“to finish the homework”,形容词easy作
宾语补足语,故选C。

真题三:用所给词的适当形式填空(t指时间/距离)
(2024广东深圳期末,北师大版)
_(it)is about 5 kilometers from my home to school
(it)took me two hours to finish reading the book yesterday.
答案:1.It2.t
核心知识点:
it可指代时间、距离、天气等抽象概念,无实际意义,在句中作主语。指时间时常用“It takes sb:
+时间+to do sth.”结构:指距离时常用“Itis+距离+from.to.”结构。
解析:
第一句描述距离,用t指代“从我家到学校的距离”:第二句描述时间,用t指代“昨天读完书这
件事花费的时间”,均需大写首字母。
真题四:句型转换(强调句结构)
(2023湖北武汉期中,北师大版)按要求改写句子,每空一词。
Tom bought a new bike last week.(用it强调划线部分“Tom”)
bought a new bike last week.
答案:It was Tom
核心知识点:
强调句基本结构为“It is/was+被强调部分+that/who+其他部分”,强调人时可用who,强调物或
时间/地点时用that。
解析:原句主语“Tom”为被强调部分,时态为一般过去时,故强调句结构为“It was+被强调部
分(Tom)+who+其他部分”,此处who可省略,答案为“It was Tom”。
真题五:短文填空(综合运用)
(2024江苏南京期末,北师大版)阅读短文,用t的适当形式填空,使短文通顺。
Hello,everyone!1.-is necessary for us to keep healthy.My mother always says 2.is important to eat
more vegetables.Last Sunday,I went to the park with my friends.3.-took us half an hour to get there
by bike.The park was beautiful,and 4.was relaxing to walk in the sun.I think 5.is a good way to
spend weekends with friends.
答案:1.t2.it3.It4.it5.it
核心知识点:
it可作形式主语(如句1“to keep healthy”、句2“to eat more vegetables”)、指代时间(如句3“花
费的半小时”)、指代抽象情况(如句4“在阳光下散步”、句5“和朋友度过周末”),需根据语境
判断具体用法。
解析:
1.句指“保持健康这件事”,t作形式主语:
2.动词says后it作形式宾语,真正宾语是“to eat more vegetables”;
3.句指时间,用“It takes sb.+时间+to do sth.”结构:
4.句指“在阳光下散步”的感受,t作形式主语:
