九年级英语全一册知识点归纳
九年级英语全一册知识点归纳嗨，小伙伴们！今天咱们就来好好唠唠九年级英语全一册的那些知识点，就像打开一个装满宝藏的箱子一样，可有趣啦。
**一、词汇部分**咱先说说词汇吧。
这册书里的单词那可真是丰富多彩，就像一个大花园里各种各样的花朵。
有些单词像“ambition（抱负，雄心）”，这个词可厉害啦。
你想啊，要是一个人没有ambition，那就像一艘没有航向的船，只能在大海里瞎晃悠。
你身边有没有那种特别有ambition的朋友呢？我就有个同学，他的ambition是当一名出色的科学家，每天都像打了鸡血似的学习科学知识。
还有像“congratulate（祝贺）”这个词，经常会用到。
比如说你朋友考试考得好，你就得说“Congratulations！”。
我记得有一次我朋友参加英语演讲比赛拿了奖，我大声地对他说“Congratulations！You are so amazing！”那感觉可棒了。
哦对了，和它相关的名词是“congratulation”，得用复数形式哦，这就像数学里的一些小规则，虽然有点麻烦，但记住了就很简单。
再看“energetic（精力充沛的）”这个词。
那些精力充沛的人啊，就像小太阳一样，总是充满活力。
我邻居家的小孩就是这样，整天跑来跑去，精力好像永远用不完似的。
你要是想要形容一个人活力满满，这个词就再合适不过了。
**二、语法点**语法可算是英语学习里的“硬骨头”了，但咱不怕，咬着牙也能把它嚼碎。
比如说一般现在时，这就像我们日常生活里的常规动作。
“I often go to school by bike.”（我经常骑自行车去上学）。
就像每天太阳都会升起一样，这是一种常态。
它的第三人称单数形式可别忘了加“s”或者“es”，就像给这个句子穿上一件合适的小外套，不然就会闹笑话啦。
还有被动语态，这就有点像东西被别人摆弄的感觉。
“The book was written by Lu Xun.”（这本书是鲁迅写的）。
九年级英语知识点归纳整理
九年级英语知识点归纳整理一、语法知识点。
1. 被动语态。
- 结构：一般现在时的被动语态：am/is/are + 过去分词；一般过去时的被动语态：was/were+过去分词；一般将来时的被动语态：will be+过去分词；含有情态动词的被动语态：情态动词+be +过去分词。
- 用法：当不知道动作的执行者是谁，或者没有必要指出动作的执行者时，使用被动语态。
例如：The bridge was built last year.（不知道谁建的桥，只强调桥被建好了）2. 定语从句。
- 关系代词：that，which，who，whom，whose。
that既可以指人也可以指物；which指物；who指人，在从句中作主语；whom指人，在从句中作宾语；whose表示所属关系，“……的”。
例如：I like the book which/that was written by Lu Xun.（先行词book是物，关系代词可用which或that）；The boy who/that is standing there is my brother.（先行词boy是人，关系代词可用who或that作主语）- 关系副词：when，where，why。
when在定语从句中作时间状语；where作地点状语；why作原因状语。
例如：I still remember the day when I first met her.（先行词day表示时间，关系副词用when）；This is the place where we used to live.（先行词place表示地点，关系副词用where）3. 宾语从句。
- 语序：宾语从句要用陈述句语序，即“连接词+主语+谓语+其他”。
例如：He asked me where I was going.而不是He asked me where was I going.- 连接词：that（无意义，可省略，在从句中不作成分）；if/whether（“是否”，在从句中不作成分）；特殊疑问词（如what，when，where，why，how等，在从句中作相应的成分）。
九年级英语知识点汇总
九年级英语知识点汇总九年级英语知识点汇总从句1.宾语从句在复合句中，由一个句子充当宾语，这个句子叫做宾语从句。
宾语从句主要有三种类型，分别是that引导的宾语从句、if或whether引导的宾从、连接代词和连接副词引导的宾语从句。
常见的宾语从句引导词：that、if、whether、what、who、where、why和how。
Eg. I am sad that you refused me. 我很难过你拒绝了我。
2.定语从句定语从句在中考和高考中出现的频率都非常高。
在复合句中，修饰名词或代词的从句叫定语从句。
被修饰的名词或代词叫先行词。
定语从句一般放在先行词的后面。
常见的关系代词包括that,which,who(宾格whom，所有格whose),as 等，关系副词包括where,when,why等。
Eg. Lily likes music that is quiet and gentle. 玛丽喜欢轻柔的音乐。
3.状语从句状语从句就是由一个句子在复合句中充当状语。
所以状语从句又可以分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句等等。
每种状语从句都有特定的引导词：(1)地点状语从句：where,wherever(2)时间状语从句：when, while, as, before, until, till, since(3)原因状语从句：because, since,as, now that, not that…, but that…, seeing that,considering that, in that(4)目的状语从句：so, so that, in order that, that, to the end that, in case,for fear that,lest(5)结果状语从句：so...that, such that, so that, with the result that(6)条件状语从句：if,unless,if only,only if,in case,suppose/supposing(that),provided/providing(that),on condition that,so/as long as(7)方式状语从句：as, as if, as though(8)让步状语从句：though, although, as, even if, even though, whether, no matterwhether...or, no matter with初中英语的学习技巧学会利用学习软件是学好初中英语的一个小技巧，尤其是现在有很多背单词的软件，非常的实用，可以帮助同学们随时随地的背单词，适合初中生的背单词软件有百词斩、墨墨背单词等等。
