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）。

一般现在时动词第三人称单数变化规则讲义与试题
一般现在时、第三人称单数动词变化规则一、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.sometimes goes to school by bike.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。
）五、一般现在时的句子转换（1）当句子中有be动词或情态动词时，则把be动词或情态动词(can,could 等等)提到主语的前面变成一般疑问句;在be动词或情态动词后面加not变成否定句.例：①陈述句：She is a student.一般疑问句→Is she a student否定句→She is not a student.②陈述句：I can swim.一般疑问句→Can you swim否定句→I can not swim.（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。
英语动词第三人称单数形式的变化规则
英语动词第三人称单数变化规则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：1、变否定句:含有动词第三人称单数形式的句子变否定句时,要在动词前面加上does ｎ’t 或doｅs not，动词的第三人称单数形式要还原成原形:格式为ｄoｅｓｎ’t/doeｓnot +动词原形，如：Hｅgoes to school ａt ｓix in tｈｅmorning。
（变否定句)→He doesｎ’t go ｔoｓchoolａｔｓiｘin the morｎing。
2、变一般疑问句：把含有动词第三人称单数形式的变成一般疑问句时,要借用助动词ｄｏes,如：Ｓhe goeｓｈoｍe aｔｆiｖｅｅverｙｄａy。
→Doｅｓsｈｅgo hoｍe at ｆｉve every day？—－—Yes，she doeｓ./No, she doesn’t。
3、对划线部分进行提问(变特殊疑问句）：一般格式为Whxxx + 一般疑问句?She goes home at five eｖerｙdａy。
(对划线部分提问）→Ｗｈen/What time doｅｓｓhｅｇｏhoｍe eveｒy day?Shｅgoｅs ｈome aｔfｉvｅeｖeｒy ｄay。
(对划线部分提问)→Who goeｓhｏme aｔｆｉｖｅevｅry ｄay?Ｓｈeｇoeｓhｏｍe at ｆｉve eveｒy day。
（对划线部分提问）→What doeｓshe do at fｉvｅevｅrｙday？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.Sｈe haｓluｎｃｈaｔtwelve. 她十二点吃午餐.Ｉｔlooks like a cat。
它看起来像只猫.2、单个人名、地名或称呼作主语;是第三人称单数。
如：Han Ｍeｉｌooks like her mother。
