一般现在时动词第三人称单数变化规则.doc

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
原形
第三人称单数形式
1、一般情况下，直接在动词词尾+s
get
take
play

2、以s, x, sh, ch, o结尾的动词，在词尾+ es
guess
fix
finish
teach
go和do
guesses
fixes
finishes
teaches
goes和does
3、以辅音字母+ y 结尾的动词，先把y变为i，再加es
study
try
fly
carry
worry
studies
tries
flies
carries
worries
4、不规则动词（特殊情况）
have
be
has
is

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.
