专题04 it作形式主语和形式宾语（寒假复习讲义） 内容导航 考点聚焦：归纳核心考点 & 高考考点，有的放矢 重点速记：重难点梳理，查漏补缺，即时巩固 复习提升：真题感知 & 综合提升专练，全面突破 it作形式主语和形式宾语是高考英语语法的高频考点，核心作用是避免句子“头重脚轻”，将真正的主语/宾语后置，二者在结构、用法上既有共性也有明确区分。 考点一 it作形式主语 知识精讲 it作形式主语时，仅起占位作用，真正的主语为不定式、动名词或从句，置于句末，核心结构分三类，各有固定用法和易错点。 1. 不定式作真正主语 • 核心结构 ① It + be + adj./n. + (for/of sb) + to do sth：形容词/名词描述事物性质（important/necessary/a pity）用for sb，描述人的品质（kind/nice/foolish）用of sb。 ② It takes sb + 时间 + to do sth：表“做某事花费某人多长时间”。 • 典型例句 It is important for us to learn English well.（for sb，表事物性质） It is kind of you to help me.（of sb，表人的品质） It takes me 2 hours to finish homework. • 高考高频标志词：important、necessary、a pity、a shame、take（表花费） • 易错警示：准确区分for sb和of sb的使用场景，避免将描述人的品质的形容词与for sb搭配。 2. 动名词作真正主语 • 核心结构：It + be + no use/good/useless/worthwhile + doing sth，表“做某事是没用的/值得的”。 • 典型例句：It is no use crying over spilt milk. • 高考高频标志词：no use/good、useless、worthwhile • 易错警示：该结构中动名词doing不可替换为不定式to do，这是高考的固定考法。 3. 从句作真正主语 • 核心结构：It + be + adj./过去分词 + that从句，常见形容词/过去分词有obvious、said、reported、believed等。 • 典型例句：It is said that he will come tomorrow. • 高考高频标志词：said、reported、believed、obvious • 易错警示：从句需用陈述语序，即使从句表达疑问含义，也不能用疑问语序（如It is unknown where he went，非where did he go）。 好题精练 1. It is necessary for us ______ (take) measures to protect the environment. 2. It takes her half an hour ______ (walk) to school every day. 3. It is no good ______ (complain) about the bad service. 4. It is kind ______ you to lend me your dictionary. 5. It is reported that a new hospital ______ (build) next year in our city. 6. It is worthwhile ______ (spend) time reading classic books. 7. It is a pity that he ______ (fail) in the driving test again. 8. It is still unknown when the meeting ______ (hold). 答案： 1. to take 解析：考查“It + be + adj. + for sb + to do sth”结构，necessary是描述事物性质的形容词，后接不定式作真正主语。 2. to walk 解析：考查固定句型“It takes sb + 时间 + to do sth”，此处用不定式to walk作真正主语，表“走路去上学花费她半小时”。 3. complaining 解析：考查“It + be + no good + doing sth”结构，该结构中需用动名词作真正主语，注意不能替换为不定式。 4. of 解析：考查“It + be + adj. + of sb + to do sth”结构，kind是描述人的品质的形容词，需搭配介词of。 5. will be built 解析：考查it作形式主语，that从句作真正主语的结构。从句中a new hospital和build是被动关系，且时间状语next year表将来，故用一般将来时的被动语态。 6. spending 解析：考查“It + be + worthwhile + doing sth”结构，worthwhile后接动名词作真正主语，符合高考固定考法。 7. failed 解析：that从句作真正主语，根据语境“驾照考试没通过”是已经发生的动作，故用一般过去时。 8. will be held 解析：when引导的从句作真正主语，the meeting和hold是被动关系，结合语境用一般将来时的被动语态；注意从句用陈述语序。 考点二 it作形式宾语 知识精讲 it作形式宾语时，位于谓语动词后，真正的宾语为不定式、动名词或从句，置于宾补之后，核心结构同样分三类，需注意动词的固定搭配。 1. 不定式作真正宾语 • 核心结构：主语 + 谓语 + it + 宾补（adj./n.） + to do sth，常见谓语动词有find、think、consider、feel、make等。 • 典型例句：I find it easy to solve the problem. • 高考高频标志词：find、think、consider、feel、make • 易错警示：形式宾语it不可省略，宾补多为形容词或名词，需保证结构完整。 2. 动名词作真正宾语 • 核心结构：主语 + 谓语 + it + 宾补 + doing sth，多见于no good/use等固定搭配，常见谓语动词有think、consider、find。 • 典型例句：He thinks it no good smoking. • 高考高频标志词：think、consider、find • 易错警示：该用法仅适用于no good/use等特定搭配，多数动词后不接“it + 宾补 + doing”结构。 3. 从句作真正宾语 • 核心结构 ① 主语 + 谓语 + it + 宾补 + that从句：常见谓语动词有think、make，宾补多为a pity、a shame等。 ② 动词 + it + if/when从句：常见动词有appreciate、hate，表“对……表示感激/讨厌”。 • 典型例句 We think it a pity that she can't come. I appreciate it if you help me. • 高考高频标志词：think、make、appreciate、hate • 易错警示：appreciate后必须先接形式宾语it，再接从句，不可直接接从句（如不可说I appreciate if you help me）。 好题精练 1. I find ______ necessary to take notes in English class. 2. She thinks ______ no use crying over spilt milk. 3. We consider ______ our duty to protect the environment. 4. He made ______ clear that he would attend the meeting. 5. I appreciate ______ if you could lend me your dictionary. 6. They feel ______ a shame that they missed the concert. 7. Tom thinks ______ important learning English well. 8. She hates ______ when people talk loudly in the library. 答案： 1. 答案：it 解析：考查不定式作真正宾语的结构 主语 + find + it + adj. + to do sth。it 作形式宾语，真正宾语是 to take notes in English class，necessary 作宾补。 2. 答案：it 解析：考查动名词作真正宾语的固定搭配 think it no use doing sth。it 作形式宾语，真正宾语是 crying over spilt milk，no use 作宾补。 3. 答案：it 解析：考查不定式作真正宾语的结构 主语 + consider + it + n. + to do sth。it 作形式宾语，真正宾语是 to protect the environment，our duty 作宾补。 4. 答案：it 解析：考查从句作真正宾语的结构 主语 + make + it + adj. + that从句。it 作形式宾语，真正宾语是 that he would attend the meeting，clear 作宾补。 5. 答案：it 解析：考查固定搭配 appreciate it if 从句。it 作形式宾语，不可省略，if 从句为真正宾语。 6. 答案：it 解析：考查从句作真正宾语的结构 主语 + feel + it + n. + that从句。it 作形式宾语，真正宾语是 that they missed the concert，a shame 作宾补。 7. 答案：it 解析：考查动名词作真正宾语的结构 主语 + think + it + adj. + doing sth。it 作形式宾语，真正宾语是 learning English well，important 作宾补，注意该用法需结合语境和固定搭配使用。 8. 答案：it 解析：考查固定搭配 hate it when 从句。it 作形式宾语，when 从句为真正宾语。 考点三 形式主语与形式宾语的核心区别 知识精讲 二者虽都用it作形式替代，但在句中位置、结构逻辑上差异显著，是高考的易混考点。 1. 位置不同：形式主语it位于句首，对应It + be + ... + 真正主语的结构；形式宾语it位于谓语动词后，对应谓语 + it + 宾补 + 真正宾语的结构。 2. 连接成分不同：形式主语结构中，it后接be动词作系动词，再跟表语（adj./n.）；形式宾语结构中，it后接宾补（adj./n.），无系动词参与。 3. 功能指向不同：形式主语解决的是“主语过长导致句首臃肿”的问题；形式宾语解决的是“谓语动词后宾语过长，宾补无处安放”的问题。 好题精练 1.
