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。
