高中英语语法知识点系统总结

一、英语句子结构基础

1.1 句子成分与词性对应

英语句子的核心由八大成分构成，每种成分由特定词性担任：

主语：句子的主体，通常由名词、代词、动名词或不定式充当

• 名词：The book is interesting.
• 动名词：Swimming keeps you healthy.
• 不定式：To err is human.

谓语：表示主语的动作或状态，由动词充当

• 实义动词：She writes novels.
• 连系动词：He is a teacher.
• 助动词：They have finished the work.

宾语：动作的承受者，可由多种词性充当

• 直接宾语：I bought a computer.
• 间接宾语：She gave me a gift.
• 复合宾语：We elected him president.

定语：修饰名词或代词，主要由形容词、分词、介词短语等充当

• 形容词：a beautiful garden
• 分词：the falling leaves（现在分词）
  the broken window（过去分词）
• 介词短语：the book on the table

状语：修饰动词、形容词、副词或整个句子

• 时间状语：She arrived yesterday.
• 地点状语：He works in Beijing.
• 方式状语：They solved the problem easily.

补语：补充说明主语或宾语

• 主语补语：He was elected monitor.
• 宾语补语：I found the book interesting.

表语：位于系动词后说明主语

• 名词：His father is a doctor.
• 形容词：The weather became cold.

同位语：解释说明前面的名词

• My friend Tom will come tomorrow.

1.2 五种基本句型

掌握基本句型是分析复杂句子的前提：

1. 主语 + 谓语 (SV)

• Birds fly.
• The sun rises.

2. 主语 + 谓语 + 宾语 (SVO)

• Students need knowledge.
• She loves music.

3. 主语 + 谓语 + 间接宾语 + 直接宾语 (SVOO)

• My mother bought me a watch.
• 注意：可改为”主语+谓语+直接宾语+to/for+间接宾语”
  My mother bought a watch for me.

4. 主语 + 谓语 + 宾语 + 宾语补足语 (SVOC)

• We call him Little Tiger.
• They painted the wall white.

5. 主语 + 系动词 + 表语 (SVP)

• 常见系动词：
  • be动词：am, is, are, was, were
  • 感官动词：look, sound, smell, taste, feel
  • 变化类：become, get, grow, turn, go
  • 状态保持类：keep, stay, remain

二、动词时态系统

2.1 时态基本框架（以do为例）

2.2 重点时态详解

现在完成时 (Present Perfect)

• 构成：have/has + 过去分词
• 核心用法：
  1. 过去动作对现在的影响：I have lost my key.（现在没钥匙）
  2. 过去开始持续到现在的动作：He has lived here for 10 years.
  3. 过去经历：Have you ever been to Japan?
• 时间状语标志词：already, yet, just, ever, never, since, for, recently, lately

过去完成时 (Past Perfect)

• 构成：had + 过去分词
• 使用场景：
  1. “过去的过去”：When I arrived, the film had already started.
  2. 与by, before等连用：By the end of last year, we had learned 2000 words.
• 注意事项：在before/after从句中，因时间关系明确，可用一般过去时代替过去完成时

将来进行时 (Future Continuous)

• 构成：will be + 现在分词
• 特殊用法：表示已安排或预测要发生的动作
  This time tomorrow I’ll be flying to New York.

2.3 时态呼应原则

在宾语从句和间接引语中，时态需与主句保持一致：

• 主句现在时，从句根据需要可用任何时态
  He says he is/was/will be a teacher.
• 主句过去时，从句必须用相应的过去时态
  He said he was/had been/would be a teacher.
• 例外情况：从句表达客观真理、格言时，保持一般现在时
  The teacher said the earth moves around the sun.

三、被动语态全解

3.1 构成方式

be动词 + 过去分词（be动词体现时态、人称和数）

3.2 各时态被动形式示例

• 一般现在时：English is spoken widely.
• 现在进行时：The road is being repaired.
• 现在完成时：The work has been finished.
• 一般过去时：The window was broken.
• 过去进行时：The meal was being prepared.
• 一般将来时：The meeting will be held.
• 含情态动词：The problem must be solved.

3.3 特殊结构的被动语态

1. 双宾语动词：通常将间接宾语变为主语
   主动：He gave me a book.
   被动：I was given a book (by him). / A book was given to me (by him).
2. 复合宾语：宾语补足语保留
   主动：We call him Tom.
   被动：He is called Tom.
3. 短语动词：介词/副词不可省略
   主动：They laughed at him.
   被动：He was laughed at.
4. 省略to的不定式作宾补，变被动时要加to
   主动：I saw him enter the room.
   被动：He was seen to enter the room.

3.4 不能用被动语态的情况

• 不及物动词（无宾语）：happen, occur, rise, appear等
• 连系动词：be, become, seem, feel等
• 表示状态的及物动词：have, own, possess, suit, fit等
• 某些动词短语：take place, lose heart, belong to等

四、非谓语动词精析

4.1 动词不定式 (Infinitive)

基本形式：to do（否定：not to do）

句法功能：

1. 主语：To see is to believe.
   （常用it作形式主语：It is important to learn English.）
2. 宾语：want to do, decide to do, promise to do
3. 宾补：ask sb. to do, allow sb. to do
4. 定语：I have a lot of work to do.（与被修饰词有动宾关系）
5. 状语：表目的、结果、原因
   He came to see me.（目的）
   I’m glad to hear that.（原因）

特殊结构：

• too…to…：太…而不能…
  He is too young to go to school.
• enough to…：足够…可以…
  He is old enough to go to school.
• only to…：表示意外的结果
  He hurried to the station only to find the train had left.

4.2 动名词 (Gerund)

形式：动词-ing（否定：not doing）

句法功能：

1. 主语：Swimming is good for health.
2. 宾语：
   • 作动词宾语：enjoy doing, finish doing, avoid doing
   • 作介词宾语：be interested in doing, look forward to doing
3. 表语：Her job is teaching.
4. 定语：a swimming pool（表示用途）

需接动名词的常见动词/短语：

• 建议冒险不推迟：suggest, advise, risk, delay, postpone
• 考虑容忍盼原谅：consider, allow/permit, look forward to, excuse/pardon
• 保持成功勤练习：keep, succeed in, practice
• 避免错过求完成：avoid, miss, require, finish

4.3 现在分词 (Present Participle) 与过去分词 (Past Participle)

区别对照表：

句法功能：

1. 定语：
   • 单个分词前置：a sleeping baby, a broken glass
   • 分词短语后置：The man standing there is my teacher.
2. 状语（表时间、原因、条件、伴随等）：
   • Seeing from the hill, we can see the whole city.（时间/条件）
   • Deeply moved, he thanked her again and again.（原因）
   • He sat at the window, reading a book.（伴随）
3. 补语：
   • 感官动词后：I saw him crossing the street.
   • with复合结构：With the work done, he went home.

独立主格结构：分词有自己的逻辑主语

• Weather permitting, we’ll go hiking tomorrow.
• He rushed into the room, his face covered with sweat.

五、名词性从句系统

5.1 四大名词性从句

1. 主语从句
   • That he will come is certain.
   • It is certain that he will come.（更常用）
2. 宾语从句
   • 动词后：I know (that) he is honest.（that可省略）
   • 介词后：It depends on whether he will come.（介词后不用if）
   • 形容词后：I’m sure (that) you will succeed.
3. 表语从句
   • The fact is that he didn’t notice the car.
   • That is why I was late.
4. 同位语从句
   • 对抽象名词进行解释：news, fact, idea, hope, belief等
   • The news that our team won is exciting.
   • 与定语从句的区别：同位语从句是解释内容，定语从句是修饰限定

5.2 连接词选择

• that：只起连接作用，无词义，在从句中不充当成分
• whether/if：表示”是否”，在从句中不充当成分
  （注意：主语从句、表语从句、介词后的宾语从句用whether不用if）
• 连接代词：who, whom, whose, which, what，有词义，在从句中充当成分
• 连接副词：when, where, why, how，有词义，在从句中作状语

5.3 语序与时态

• 名词性从句一律用陈述语序：主语+谓语
  错误：I don’t know where is he.
  正确：I don’t know where he is.
• 时态呼应（见第二章2.3节）

六、定语从句深度解析

6.1 关系词选择

6.2 限制性 vs 非限制性定语从句

6.3 特殊注意事项

1. 只能用that的情况：
   • 序数词、最高级修饰先行词时：This is the best film that I’ve seen.
   • all, much, little, none等不定代词作先行词：All that can be done has been done.
   • 先行词同时包含人和物时：They talked about the persons and things that they remembered.
   • 主句以who/which开头时：Who is the man that is speaking?
2. 只能用which的情况：
   • 非限制性定语从句中：He bought a book, which cost him 50 yuan.
   • 介词后：This is the house in which he lived.
3. “介词+关系代词”结构：
   • 介词选择依据：从句中动词/形容词的固定搭配
     This is the house in which he lived.（live in）
   • 注意：固定短语中的介词一般不提前
     This is the child (whom) she will look after.（不说after whom）

七、状语从句分类详解

7.1 九种状语从句

1. 时间状语从句
   • when：动作可同时或先后发生
   • while：强调动作同时持续进行，从句动词需延续性
   • as：”一边…一边”，强调伴随
2. • 连接词：when, while, as, before, after, since, until/till, as soon as, the moment
   • when, while, as区别：
3. 地点状语从句
   • 连接词：where, wherever
   • Where there is a will, there is a way.
4. 原因状语从句
   • because：直接原因，语气最强，回答why
   • since/as：已知原因，语气较弱，”既然”
   • now that：”既然”，常与现在完成时连用
5. • 连接词：because, since, as, now that
   • 区别：
6. 目的状语从句
   • 连接词：so that, in order that, that
   • 常与情态动词can/could/may/might连用
   • He got up early so that he could catch the train.
7. 结果状语从句
   • 连接词：so…that…, such…that…
   • 结构：
     so + adj./adv. + that…
     so + adj. + a/an + 单数名词 + that…
     such + (a/an) + (adj.) + 名词 + that…
8. 条件状语从句
   • 连接词：if, unless, as/so long as, in case
   • “主将从现”原则：主句将来时，从句用现在时代替将来时
     If it rains tomorrow, we will stay at home.
9. 让步状语从句
   • 连接词：though/although, even if/even though, no matter+疑问词, however+adj./adv.
   • 注意：though/although不可与but连用，但可与yet, still连用
10. 方式状语从句
    • 连接词：as, as if/as though
    • Do as I do.
    • He talks as if he knew everything.（虚拟语气）
11. 比较状语从句
    • 连接词：than, as…as…, not so/as…as…, the more…the more…
    • He works harder than I (do).
    • The more you read, the better you understand.

7.2 状语从句的省略

当从句主语与主句主语一致，且谓语包含be动词时，可省略主语和be动词：

• When (he was) asked about his family, he said nothing.
• If (it is) necessary, I’ll explain it again.

八、虚拟语气核心规则

8.1 条件句中的虚拟语气

例句：

• If I were you, I would accept the offer.（现在）
• If he had taken my advice, he wouldn’t have failed.（过去）
• If it should rain tomorrow, the match would be put off.（将来）

倒装替代if：省略if，将were/had/should提前至句首

• Were I you (= If I were you), I would go.
• Had he come earlier (= If he had come earlier), he would have met her.

8.2 其他从句中的虚拟语气

1. wish后的宾语从句
   • 现在：过去式（be用were）
     I wish I were a bird.
   • 过去：had done 或 would/could have done
     I wish I had studied harder.
   • 将来：would/could/might+do
     I wish he would come.
2. 表示建议、命令、要求等词语后的从句
   • 动词：suggest, insist, demand, order, require等
   • 名词：suggestion, proposal, demand, order等
   • 形容词：necessary, important, essential等
   • 从句谓语用：(should) + do
     He suggested that we (should) start early.
     It is important that he (should) be informed.
3. as if/as though引导的从句
   • 与现在事实相反：过去式（be用were）
     He talks as if he knew everything.
   • 与过去事实相反：had done
     He looked as if he had seen a ghost.
4. It’s (high) time that…
   • 从句用过去式或should+do
   • It’s time we went/should go to bed.

九、主谓一致原则

9.1 三大原则

1. 语法一致原则：单数主语用单数动词，复数主语用复数动词
   • The boy is reading.
   • The boys are reading.
2. 意义一致原则：根据主语表达的实际意义决定
   • The family are having dinner.（指家庭成员）
   • The family is a big one.（指家庭整体）
3. 就近原则：谓语动词与最近的主语保持一致
   • Not only he but also I am wrong.
   • Either you or he has to go.

9.2 特殊主语的处理

1. 集合名词：
   • 常作复数：people, police, cattle
   • 根据意义决定：family, team, class, government, audience, committee
2. 数量词+名词：
   • a number of + 复数名词：用复数
     A number of students are present.
   • the number of + 复数名词：用单数
     The number of students is increasing.
   • 分数/百分数+of+名词：根据名词单复数决定
     Three-fourths of the earth’s surface is sea.
     Two-thirds of the students are from China.
3. 并列主语：
   • and连接：通常用复数
     He and I are good friends.
   • each/every…and each/every…：用单数
     Each boy and each girl has a book.
   • or, nor, either…or…, neither…nor…, not only…but also…：就近原则
4. 特殊结构：
   • 动名词/不定式/从句作主语：用单数
     Reading aloud is helpful.
   • “many a + 单数名词”：用单数
     Many a student has made the mistake.
   • “more than one + 单数名词”：用单数
     More than one person was injured.

十、倒装句与强调句

10.1 完全倒装

将整个谓语提到主语之前，条件：

1. 地点副词/介词短语位于句首：Here comes the bus. / In front of the house stands a tree.
2. 表语位于句首（尤形容词、分词）：Present at the meeting were many scientists.
3. such位于句首：Such were his words.

10.2 部分倒装

只将助动词/情态动词/be动词提到主语之前，条件：

1. 否定词或短语位于句首：Never have I seen such a beautiful place.
   常见否定词：never, seldom, hardly, scarcely, little, not, not only, no sooner…than…
2. “only+状语”位于句首：Only in this way can you learn English well.
3. so/neither/nor表示”也/也不”：He can swim, so can I. / I haven’t been there, neither has he.
4. 虚拟条件句省略if（见8.1节）
5. as/though引导让步状语从句（表语/状语/动词提前）：Child as he is, he knows a lot.

10.3 强调句 (It is/was…that/who…)

• 结构：It is/was + 被强调部分 + that/who + 句子其余部分
• 强调主语（人用who/that，物用that）：
  It was John who/that broke the window.
• 强调宾语：
  It was the window that John broke.
• 强调状语：
  It was yesterday that John broke the window.
• 判断方法：去掉It is/was…that…，句子仍完整

总结：英语语法是一个系统化的知识网络，各知识点相互关联。建议学习时：

1. 建立整体框架，理解各部分联系
2. 通过大量例句体会规则的实际应用
3. 在阅读和写作中有意识地运用所学语法
4. 定期复习，整理错题，分析原因

语法是语言的骨架，但最终目的是为了更好地理解和表达。在掌握规则的基础上，大量接触真实语境中的英语，才能实现从”懂语法”到”用英语”的跨越。
