Unit 5 A delicate world
语法专项指导
it作形式宾语
语法原句再现
①No visitor would think it surprising that the island is a UNESCO World Heritage Site.
②Experts felt it necessary to come up with a plan to remove all the rabbits from the island.
③This incident made it clear that the rat,mouse and rabbit problem needed solving once and for all.
通过观察上面3个句子可知,句中的it充当了形式宾语。还有哪些情况下it也作形式宾语呢
语法知识点拨
核心知识点拓展:it作形式宾语的3大结构深度解析
结构1:动词 + it + 宾补 + 真宾语
核心公式:V. + it + adj./n. + to do/doing/that从句
高频动词:think, find, feel, make, consider, believe
宾补形式:adj. (important) / n. (a pity)
例句:We take it our responsibility to protect the environment.
易错点:不可省略it直接加真正宾语。
结构2:喜恶动词 + it + 状语从句
核心公式:V. + it + when/if 从句
高频动词:like, dislike, hate, enjoy, appreciate, prefer
例句:I appreciate it if you can join in the activity.
关键点:此类动词后接状语从句时,必须用it作形式宾语。
结构3:动词短语 + it + that从句
核心公式:V. + prep. + it + that 从句
高频短语:rely on, depend on, insist on, see to, count on
例句:We can count on it that he will help us.
关键点:“动词+介词”短语后接that从句时,it不可省。
易混点辨析:it作形式宾语 vs it作形式主语
it 作形式宾语 (Object)
核心结构:主语 + 谓语 + it + 宾补 + 真正宾语
位置特征:it 位于谓语动词之后
核心目的:避免宾语过长,保持句子平衡
We find it important to protect animals.
it 作形式主语 (Subject)
核心结构:It + 谓语 + 真正主语 (to do/that)
位置特征:it 位于句子开头
核心目的:避免主语过长,突出核心内容
It is important to protect wild animals.
辨析小技巧:
看 it 的位置 + 是否有宾补(形容词/名词)。有宾补则为形式宾语,无则大概率为形式主语。
特殊情况补充:it作形式宾语的3个高频特例
想当然认为
结构:take it for granted that + 从句
例句:
Some people take it for granted that nature will always provide us with everything.
说明:it为形式宾语,that从句为真正宾语。
归功于某人
结构:owe it to sb that + 从句
例句:
We owe it to the scientists that many rare animals are saved from dying out.
说明:it为形式宾语,that从句为真正宾语。
动名词作真正宾语
结构:it + 宾补 + doing (少数动词)
适用动词:find, think, consider, feel
例句:
I think it useless complaining about the environment without taking action.
记忆口诀
核心记忆口诀
动词后接宾补现,it代宾语放前面;
喜恶动词接状从,it架桥在中间;
动介短语接that句,it不可丢一边;
固定搭配记心间,take/owe it是关键。
1.当复合宾语中的宾语是不定式、动名词或宾语从句时,往往用it作形式宾语,把真正的宾语放在它的补足语后面。常用于此结构的动词有feel、consider、find、believe、make、take、imagine、prove、think、suppose、regard、notice等。
I find it not easy to improve one’s oral English.
我觉得提高英语口语不容易。
He made it clear that he would stick to the end.
他明确表示他会坚持到底。

①We all regard      our duty to help those in need.
②I think it very interesting       (learn) English.
it
to learn
2.当主句的谓语是表示喜恶的动词,如like、dislike、hate、enjoy、appreciate、prefer等,且后面有when/if引导的从句时,一般把it放在主句的谓语动词后面,再接从句。
I’d prefer it if I didn’t have to do so much work.
要是我不必做那么多工作,那就太好了。
翻译句子
①如果您能考虑我的申请,我将不胜感激。


I would appreciate it if you could take my application into consideration.

②我讨厌人们在公共场所吸烟。

3.rely on、insist on、stick to、see to、depend on等由动词和介词构成的短语动词后接that宾语从句时,先加it作形式宾语,再接that从句。
Please be so kind as to see to it that all the alterations are made at once!

4.(2021·新高考全国Ⅰ卷)Jeff felt    hard to turn off the gas quickly enough.
it
真题体验
it
it
it
答案及剖析:
1.it 分析句子结构可知,谓语动词consider后缺少宾语,真正的宾语是to eat with utensils,形容词inappropriate作宾语补足语,故设空处应用it作形式宾语。
2.it 分析句子结构可知,此句为主从复合句。why引导表语从句。在表语从句中,none of the children为主语,谓语动词thought后缺少宾语,空后的形容词unusual为宾语补足语,故设空处应用it作形式宾语,指代that从句的内容。
3.it 分析句子结构可知,谓语动词see后缺少宾语,真正的宾语是to try to break the growing disconnect between people and nature,故设空处应用it作形式宾语。
4.it 分析句子结构可知,谓语动词felt后缺少宾语,真正的宾语是后面的不定式to turn off the gas quickly enough,故设空处应用it作形式宾语。
