第二部分：核心语法知识点

九年级的语法是重中之重,也是考试的难点。

宾语从句

在句子中作宾语的从句。

• 连接词:
  • that: 无实际意义，只起连接作用，在口语和非正式文体中常省略。

    I know (that) he is right.

  • if / whether: “是否”，不能省略。

    I wonder if/whether it will rain tomorrow.

    
    （图片来源网络，侵删）
  • 特殊疑问词: who, what, which, when, where, why, how 等。

    Can you tell me where the library is?

• 语序: 宾语从句必须使用陈述句语序（主语 + 谓语）。
  • 错误: Can you tell me where is the library?
  • 正确: Can you tell me where the library is?
• 时态:
  • 主句是现在时或将来时，从句可用任何所需的时态。
    • I will tell him what he needs.
    • I know he came yesterday.
  • 主句是过去时，从句要用相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）。
    • He said he was busy.
    • She told me that she would come back the next day.
  • 客观真理、事实、格言，无论主句是什么时态，从句都用一般现在时。

    The teacher told us that the earth moves around the sun.

状语从句

在句子中作状语，修饰主句的动词、形容词或副词，表示时间、地点、原因、条件、目的、结果、让步等。

• 时间状语从句: when, while, as, before, after, since, until/till, as soon as 等。
  • I will call you as soon as I arrive.
  • He was doing his homework while his mother was cooking.
• 条件状语从句: if, unless (除非，如果不) 等。
  • If it doesn't rain tomorrow, we will go hiking.
  • You will fail the exam unless you study hard.
• 原因状语从句: because, since, as (因为，由于)。

  He didn't come to school because he was ill.

  
  （图片来源网络，侵删）
• 让步状语从句: though, although (虽然.....), even though (即使), even if (即使)。
  • Although it was raining, they went on working.
  • 注意: although / though 不能与 but 连用。
    • 错误: Although he is poor, but he is happy.
    • 正确: Although he is poor, he is happy. / He is poor, but he is happy.
• 目的状语从句: so that (以便), in order that (为了)。

  He got up early so that he could catch the first bus.

• 结果状语从句: so...that... (..以至于...), such...that... (..以至于...)。
  • He was so tired that he fell asleep.
  • It was such a fine day that we decided to go for a picnic.

被动语态

强调动作的承受者,而不是执行者。

• 基本结构: be + 动词的过去分词
• 各种时态的被动语态:
  • 一般现在时: am/is/are + p.p. (e.g., English is spoken widely in the world.)
  • 一般过去时: was/were + p.p. (e.g., The bridge was built last year.)
  • 一般将来时: will be + p.p. / am/is/are going to be + p.p. (e.g., A new school will be built in our town.)
  • 含有情态动词: can/may/must/should + be + p.p. (e.g., The work must be finished on time.)
• 被动语态的用法:
  1. 不知道或没有必要指出动作的执行者。

     This book was written in 1980. (不知道谁写的)

  2. 强调动作的承受者。

     The window was broken by Tom. (强调窗户被打破了)

• 特殊形式的被动语态:
  • 带双宾语的被动语态: 把间接宾语（常指人）变为主语。
    • He gave me a book. (主动)
    • I was given a book. (被动)
    • A book was given to me. (被动)
  • 动词不定式作宾补的被动语态: 主语 + be + p.p. + to do sth.
    • The teacher asked us to clean the classroom. (主动)
    • We were asked to clean the classroom. (被动)
    • The classroom was asked to be cleaned by us. (不常用,但语法正确)

过去进行时 vs. 一般过去时

• 过去进行时: was/were + doing
  • 用法: 表示过去某个时间点或时间段正在进行的动作。
  • 标志词: at 8:00 yesterday, at that time, this time yesterday, when...
  • 例句: I was reading a book when he came in.
• 一般过去时: did / was/were + p.p.
  • 用法: 表示过去发生的动作或存在的状态,是一个完整的动作。
  • 例句: I read a book yesterday evening.
• 区别: was doing 强调动作的过程和持续性；did 强调动作的结果和完整性。

情态动词的用法

• can / could: 能力；请求或许可。
  • Can you help me? (
  • Could you help me? (更委婉的现在)
• may / might: 许可；可能性（比 may 更弱）。
  • May I come in? (许可)
  • It may rain tomorrow. (可能性)
• must: 必须；肯定推测。
  • You must finish your homework. (必须)
  • He must be at home. The lights are on. (肯定推测)
• have to: 不得不（表示客观需要）。

  I have to get up early tomorrow. (因为要赶火车,不得不)

• should / ought to: 应该。

  You should study harder.

• need: 需要 (实义动词或情态动词)。
  • You need to see a doctor. (实义动词)
  • Need I go now? (情态动词,多用于疑问句和否定句)

非谓语动词

• 动词不定式: to do
  • 作主语: To learn English well is important.
  • 作宾语: I want to go home.
  • 作宾补: My father asks me to clean my room.
  • 作目的状语: He came here to see his friend.
  • 作定语: I have a lot of work to do.
• 动名词: doing
  • 作主语: Swimming is my favorite sport.
  • 作宾语: I enjoy listening to music.
  • 作表语: My hobby is reading.

  • 现在分词: doing (表示主动和进行)。

第四部分：备考建议

1. 回归课本，夯实基础: 九年级的知识建立在七八年级之上，确保课本中的单词、短语、课文都已掌握。
2. 梳理语法，构建体系: 不要孤立地记语法规则，将宾语从句、状语从句、被动语态等核心语法点串联起来，形成知识网络，多做专项练习，特别是时态、语序和语态的转换题。
3. 精听精读，提升语感: 每天坚持听英语新闻、课文录音，阅读英语短文、简易读物，这有助于培养语感,提高对长难句的理解能力。
4. 勤于动笔，规范写作: 准备一个错题本，记录做错的题目，特别是语法题，每周至少写一篇作文，注意使用学过的从句、短语和高级词汇,并请老师或同学帮忙批改。
5. 模拟实战，查漏补缺: 在临近考试时，严格按照考试时间做几套完整的模拟题，模拟真实考场环境,锻炼时间分配能力和应试技巧。

希望这份总结能对你的学习有所帮助！祝你学习进步,取得优异成绩！
