九年级英语核心知识点归纳总结

九年级英语是整个初中阶段的收尾和升华，知识点不仅数量增多，难度和综合性也显著提升，它要求学生不仅要掌握新的语言知识，更要熟练运用已有的知识进行综合输出（写作和口语）。

第一部分：核心语法

语法是英语的骨架，九年级的语法重点是复杂从句和动词的高级用法。

宾语从句

在八年级基础上深化,掌握不同引导词的用法和语序。

引导词:
- that: 无实际意义，只起连接作用，在从句中不充当任何成分，可省略。
  I know (that) he is right.
- if/whether: “是否”，在从句中不充当成分，不可省略，常与 or not 连用。
  - Please ask if/whether he will come.
  - I don't know whether it will rain or not.
- 特殊疑问词 (what, where, when, why, how, who 等): 在从句中充当主语、宾语、表语或状语。
  - Can you tell me where the bus station is? (作表语)
  - I wonder what he is doing. (作宾语)
语序: 宾语从句必须使用陈述句语序 (主语 + 谓语)。

- 错误：Do you know where is he?
- 正确：Do you know where he is?
时态一致性: 如果主句是现在时或将来时，从句可根据实际情况使用任何时态，如果主句是过去时，从句通常需要使用相应的过去时态 (一般过去时、过去进行时、过去完成时等)。
- He said (that) he was busy.
- She told me that she would come.

状语从句

这是九年级语法的重点和难点，主要掌握时间、条件、原因、让步、结果、目的等状语从句。

时间状语从句: 由 when, while, as, before, after, since, till/until, as soon as 等引导。
- when, while, as 的区别:
  - when: 可指“在...时”（点或段），主从句动作可同时发生,也可一前一后。
  - while: 强调“在...期间”（段），主从句动作通常同时进行,从句常用进行时。
  - as: 强调“一边...一边...”，或“随着...”。
- 时态: when, as soon as, not...until 等引导的从句，若用 一般现在时，主句用 一般将来时。
  - I will call you as soon as I arrive.
条件状语从句: 由 if, unless (除非，如果不) 引导。
（图片来源网络，侵删）
- 时态: 同样遵循“主将从现”原则。
  - If it rains tomorrow, we will cancel the picnic.
原因状语从句: 由 because, since, as 引导。
- because: 语气最强，回答 why 提出的问题。
- since/as: 语气较弱，意为“由于，既然”,常表示对方已知的事实或理由。
让步状语从句: 由 though, although, even though/if 引导。
- 注意: though/although 不能与 but 连用，但可与 yet, still 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.
结果状语从句: 由 so...that... (..以至于...) 和 such...that... (..以至于...) 引导。
- so + adj./adv. + that...
  - He was so tired that he fell asleep.
- such + (a/an) + adj. + n. + that...
  - It was such a nice day that we went out for a walk.
目的状语从句: 由 so that, in order that 引导，从句中常含有 can, could, may, might, will, would 等情态动词。
- He got up early so that he could catch the first bus.

情态动词

掌握 can, may, must, should, need, used to 等情态动词的过去式和用法。

can/could: could 是 can 的过去式，也可表示更委婉的请求。
Could you help me? (比 Can you? 更礼貌)
may/might: might 是 may 的过去式，可能性比 may 更小。
must/have to:
- must 表示主观“必须”，否定式 mustn't 表示“禁止”。
- have to 表示客观“不得不”，有人称和数的变化，否定式 don't/doesn't have to 表示“不必”。
should: 应该,建议。
need: 需要,用作情态动词时多用于否定句和疑问句。
used to: 过去常常做某事，现在不做了。
- He used to smoke, but he doesn't now.

被动语态

九年级重点学习各种时态的被动语态。

基本结构: be + 动词的过去分词
常见时态:
- 一般现在时: am/is/are + p.p.
- 一般过去时: was/were + p.p.
- 一般将来时: will be + p.p. / am/is/are going to be + p.p.
- 现在完成时: have/has been + p.p.
- 含有情态动词: can/may/must/should + be + p.p.
主动变被动:
1. 宾语变主语。
2. 谓语动词变 be + p.p.。
3. 主语变 by + 宾格,可省略。
- 主动：We clean the classroom every day.
- 被动：The classroom is cleaned by us every day.

非谓语动词

重点是动词不定式 to do 的用法。

作宾语: want, hope, decide, agree, learn, plan, try 等动词后常接 to do。
- I want to learn French.
作宾语补足语: ask, tell, want, would like, invite 等动词后。
- The teacher told us to keep quiet.
作目的状语: to do 或 in order to do。
- He studies hard to pass the exam.
作定语: 放在名词后面，表示“做...的”。
- I have a lot of work to do.
“疑问词 + to do” 结构: 作主语、宾语等。
- How to solve the problem is a big question. (作主语)
- I don't know what to do. (作宾语)
