初中一般现在时与三单动词的变化规则
I play basketball.（我打篮球）
You like swimming.（你喜欢游泳）
然而，当主语是第三人称单数（he，she，it或者一个名词单数）时，动词需要根据以下规则进行变化：
1. 动词以一般情况下的变化方式（即动词原形）+ s或es结尾。
- 例如：He plays basketball.（他打篮球）
She runs very fast.（她跑得很快）
The cat eats fish.（猫吃鱼）
2. 如果动词以s, ss, x, sh, ch等结尾，加es。
- 例如：She washes her hands.（她洗手）
3. 动词以辅音字母+y结尾时，变y为i，再加es。
- 例如：He studies hard.（他努力学习）
需要注意的是，以下动词有不规则变化：
1. be的现在时单数形式是am（I am），is（he is，she is，it is）；
2. have的现在时单数形式是has（he has，she has，it has）。

英语三单变化规则
英语三单变化规则英语中，动词的三单变化规则是指当主语是第三人称单数时，动词的形式会发生变化。
一般来说，动词在一般现在时的三单变化规则有以下几种情况：1.一般规则动词的变化规则对于大多数动词，只需要在动词原形（即第一人称单数形式）末尾加上字母“s”即可，表示动词的第三人称单数形式。
例如：- I work (我工作) → He works (他工作)- You run (你跑步) → She runs (她跑步)- They eat (他们吃) → It eats (它吃)2. 以s、 x、 ch、 sh 和 o 结尾的动词对于以字母“s”、”x”、”ch”、”sh”和“o”结尾的动词，需要在动词原形后面加上字母“es”来表示动词的第三人称单数形式。
例如：- I kiss (我亲吻) → She kisses (她亲吻)- He washes (他洗) → It washes (它洗)- They fix (他们修理) → She fixes (她修理)- He goes (他去) → She goes (她去)3.以辅音字母+y结尾的动词对于以辅音字母“y”结尾的动词，需要将“y”变为“i”，并加上字母“es”来表示动词的第三人称单数形式。
例如：- I study (我学习) → He studies (他学习)- You fly (你飞) → She flies (她飞)- They try (他们尝试) → It tries (它尝试)4.以“o”结尾的动词对于以字母“o”结尾的动词，一般来说，需要在动词原形后面加上字母“es”来表示动词的第三人称单数形式。
例如：- I do (我做) → He does (他做)- You go (你去) → She go es (她去)- They have (他们有) → It has (它有)5.不规则动词除了以上的规则动词之外，还有一些动词的第三人称单数形式是不规则的，需要记住其具体形式。

三单的变化规则
三单的变化规则三单的变化规则是指英语动词在第三人称单数形式下的变化规律。
在英语中，动词的变化主要包括三个方面：人称、数和时态。
人称分为第一人称、第二人称和第三人称，数分为单数和复数，时态包括一般现在时、一般过去时和一般将来时等。
本文将重点介绍第三人称单数形式下的变化规则。
在一般现在时中，第三人称单数形式的变化规则是在动词原形后加上-s或-es。
具体规则如下：1. 对于以辅音字母+y结尾的动词，将y变为i，再加上-es。
例如：study→studies，fly→flies。
2. 对于以s, x, ch, sh, o结尾的动词，加上-es。
例如：pass→passes，fix→fixes，watch→watches，go→goes。
3. 对于以辅音字母+o结尾的动词，通常加上-es，但也有一些例外。
例如：do→does，go→goes。
4. 对于以辅音字母+o结尾的动词，当其前面有元音字母时，只加-s。
例如：go→goes，do→does。
5. 对于以辅音字母+y结尾的动词，当其前面有元音字母时，只加-s。
例如：play→plays，say→says。
6. 对于以辅音字母+ch, sh, x结尾的动词，当其前面有元音字母时，只加-s。
例如：teach→teaches，wash→washes。
在一般过去时中，第三人称单数形式的变化规则是在动词原形后加上-ed或-d。
具体规则如下：1. 对于以辅音字母+e结尾的动词，直接加上-d。
例如：live→lived，hope→hoped。
2. 对于以重读闭音节结尾的动词，双写最后一个辅音字母，再加上-ed。
例如：stop→stopped，plan→planned。
3. 对于以辅音字母+y结尾的动词，将y变为i，再加上-ed。
例如：study→studied，carry→carried。
4. 对于以辅音字母结尾的动词，当其前面是元音字母时，双写最后一个辅音字母，再加上-ed。
动词三单的变化规则总结
动词三单的变化规则总结，别再搞错了！各位同学：说都动词，我们要知道，动词的变化和句子的时态是有一定关系的。
今天咱们要说的是一般现在时，它的动词变化。
一般现在时：指经常发生的动作或现阶段的状态。
例：We ofen play football on Sunday. She always goes shopping with her friends at the weekend.这两个句子描述的是经常发生的动作，是一般现在时。
我们会发现，在一般现在时里，一般动词是用原型（根据主语判断）；当主语是第三人称单数时，用动词三单形式。
动词的三单变化规则小试牛刀：一、写出下列动词的三单形式。
1. play_____ brush_____ say_____2. stop_____ fix_____ live_____3. take_____ run_____ enjoy_____4. do_ ____ get_____ watch_____5. have_____ work_____ go_____6. cook_____ make_____ sing_____7. study__ ___ fly_____ teach_____8. sit_____ like_____ dance_____9. look_____ draw_____ grow_____10. kiss___ __ buy_____ want_____二、用所给词的适当形式填空。
1. We often _____(play) in the playground.2. He _____ (get) up at six o'clock.3. Mike sometimes _____(go) to the park with his sister.4. He often _____(have)dinner at home.5. Mike _____(like) cooking.6. Mrs White_____(teach) us English.7. Mary usually _____(get) up at seven in the morning.8. I often _____ (take) a shower at nine.9. Your brother often _____(brush) his teeth at noon.10.My parents always ___(read)books after lunch.。

一般现在时动词第三人称单数变化规则
一、概述一般现在时的概念和用法：（1）表示现阶段经常、反复、习惯性的动作;（2）表示目前的状况；（3）表示自然界的客观真理。
二、一般现在时的结构时态的结构指的是动词的变化形式。
一般现在时间有两种结构，一种是动词原形，用于主语为非第三人称时的情况；另一种为动词的第三人称单数形式，用于主语为第三人称时的情况。
Eg1. We often get up early in the morning.Eg2. My father often gets up early in the morning.三、谈谈“主语为三单，其后动词s添”在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。
可以简单叙述为“主语为三单，其后动词s添”。
何谓第三人称单数用一句话概括就是“非你、非我、非复数”，如he, she, it, my father, my mother, my sister, our English teacher, Tom, Mike, Liu Jia, China, my book, etc.Eg3.He sometimes goes to school by bike.Eg4.My father works in the hospital as a doctor.四、一般现在时的肯定句中，主语为第三人称单数的动词变化主要体现在词尾的变化上，其规律为：（与名词变成复数的变法大致相同。
）（2）当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does（单数she,he,it）变成一般疑问句；在主语后谓语动词前加助动词don’t（I,you,以及复数), doesn’t（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。
例：①陈述句：We get up at 7:00 every morning.一般疑问句→Do you get up at 7:00 every morning?否定句→We don’t get up at 7:00 every morning.②陈述句：She has a little brother.一般疑问句→ Does she have a little brother?否定句→ She doesn’t have a little brother.哪些主语是第三人称单数1、人称代词he, she, it；如：He likes watching TV. 他喜欢看电视。

例：①陈述句：We get up at 7:00 every morning.一般疑问句→Do you get up at 7:00 every morning?否定句→We don’t get up at 7:00 every morning.②陈述句：She has a little brother.一般疑问句→ Does she have a little brother?否定句→ She doesn’t have a little brother.五、哪些主语是第三人称单数？1、人称代词he, she, it；如：He likes watching TV. 他喜欢看电视。
