一般现在时动词第三人称单数变化规则

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。）

规则 1、一般情况下，直接在动词词尾+s 原形 get take play guess fix finish teach go和do study try fly carry worry have be 第三人称单数形式 gets takes plays guesses fixes finishes teaches goes和does studies tries flies carries worries has is 2、以s, x, sh, ch, o结尾的动词，在词尾+ es 3、以辅音字母+ y 结尾的动词，先把y变为i，再加es 4、不规则动词（特殊情况） 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。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.
