英语动词第三人称单数变化规则

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: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如:get take play gets takes plays2、以s, x, sh, ch, o结尾的动词,在词尾+ esguess fix finish teach go和do guesses fixes finishes teaches goes和does3、以辅音字母+ y 结尾的动词,先把y变为i,再加esstudy try fly carry worrystudies tries flies carries worries4、不规则动词(特殊情况)have behas is1、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doesn’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/does not + 动词原形,如: He goes to school at six in the morning. (变否定句)→He doesn’t go to school at six in 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 goes home at five every day。

→Does she go home at five every day?—-- Yes, she does。

/No, she doesn’t。

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 has lunch at twelve。

她十二点吃午餐. It looks 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 Mei looks like her mother. 韩梅看起来像她的母亲。

动词三单的变化规则

动词三单的变化规则

动词三单的变化规则
动词的三单形式是指在第三人称单数主语(he、she、it)下的动词变化。

一般情况下,在动词三单形式中,动词要加-s、-es或-ies。

具体的变化规则如下:
1. 一般规则:大多数动词在第三人称单数时,直接在动词原形后添加-s。

例如:play → plays,talk → talks,run → runs。

2. 以-s、-ss、-sh、-ch、-x、-o结尾的动词:在这些动词的第三人称单数形式中,要在动词原形后添加-es。

例如:pass → passes,brush → brushes,wash → washes,watch → watches。

3. 以辅音字母+y结尾的动词:如果辅音字母y前面是元音字母,则直接在动词原形后添加-s。

例如:play → plays。

如果辅音字母y前面是辅音字母,则将y改为i,再加-es。

例如:carry → carries,study → studies。

4. 不规则变化的动词:有一些动词的第三人称单数形式变化不遵循以上规则,需要记忆这些不规则变化。

例如:be → is,have → has,do → does,go → goes。

需要注意的是,动词的三单形式还会受到时态、语气和语法结构等因素的影响,有时会发生变化。

因此,需要根据具体的语境来确定动词的变化形式。

英语三单形式变化规则

英语三单形式变化规则

英语三单形式变化规则英语动词的第三人称单数形式是指在主语为第三人称单数(he, she, it, 名词单数等)时,动词的形式发生变化。

一般来说,动词的第三人称单数形式要在动词词尾加上-s、-es或-ies。

但是也有一些特殊情况和不规则变化需要注意。

下面将详细介绍英语动词三单形式的变化规则。

一般规则:1.大多数动词在第三人称单数形式时,在词尾加上-s。

例如:speak → speaks;run → runs;work → works;play → plays2. 如果一个动词以s、x、ch、sh 结尾,动词第三人称单数形式应该在词尾加上-es。

例如:pass → passes;fix → fixes;watch → watches;brush→ brushes3. 动词以辅音字母+y结尾,转变为以辅音字母+i+y结尾,然后在词尾加上-es。

例如:study → studies;carry → carries;try → tries4. 动词以辅音字母+o结尾,第三人称单数时,在词尾加上-es。

例如:do → does;go → goes;echo → echoes5.动词以辅音字母+o结尾,前面有一个元音字母,第三人称单数时,只加-s。

例如:piano → pianos;photo → photos6. 动词以辅音字母+consonant字母+ y 结尾,将y改为ies。

例如:study → studies;fly → flies;cry → cries7.动词以“辅音字母+_y”的形式结尾,但是该辅音字母前是一个元音字母。

这种情况下,动词的第三人称单数形式在词尾加上-s。

例如:play → plays;pray → prays;enjoy → enjoys不规则变化:除了一般的规则以外,还有一些常见的动词变化形式是不规则的,需要单独记忆。

1. be → is(am,are)例如:She is a student. → He is a teacher.注意:be动词变化形式较为特殊,主语为第三人称单数时,is是be 动词的正确形式。

英语三单规则

英语三单规则

英语三单规则
英语三单形式变化规则:(1)一般情况,三单形式直接加s;(2)以s、x、ch、sh、o结尾,加es;(3)以辅音字母+y结尾,变y为i再加es;(4)特殊情况不规则变化,如have的三单形式为has等。

英语三单形式介绍:
一、定义
第三人称单数是英语中的一种语法,也称“三单”或“单三”,用于一般现在时的句子,当动词在第三人称后时。

二、变化规则
1、一般情况,直接加s。

run→runs;get→gets
注意:大多数实义动词在词尾加“s”在清辅音后发音为/s/;在浊辅音及元音音素后发音为/z/。

例如:speak→speaks /s/;come→comes /z/;play→plays /z/。

2、以s、x、ch、sh、o结尾,加es。

pass→passes;fix→fixes;watch→watches;teach→teaches;wash→washes;go →goes;do→does
注意:以“s、x、ch、sh”结尾的动词在词尾加“es”发音为/iz/;以“o”结尾的动词,常出现的两个以“o”结尾的动词go和do后加“es”读/z/。

3、以辅音字母+y结尾,变y为i再加es。

study→studies;fly→flies
4、特殊情况不规则变化。

have→has
