解题攻略——关于一般现在时的主语三单形式在英语考试中,主语是第三人称单数(简称三单)的一般现在时是必考内容。
经常以选择和填空的形式出题。
我们该怎么把题做对呢?请按以下步骤来审题:①首先寻找表示时态的标志性词语,判断句子的时态。
②如果时态是一般现在时,去看句子开头的主语是不是第三人称单数。
③什么样的主语是第三人称单数?记住下面的口诀口诀如下:1.he、she、it 和人名,2.谁的亲戚,谁的爸妈3.this 、that、the、a、an,4.出现在单数前是三单5.地名、国名当排头6.一定是三单别放松7.不可数名词当主语8.也是三单别放过9.以上情况一出现10.动词原形变变变注解:1. He、she、it 和人名解释:男他、女她、指物的它以及具体的人名如:Tom, Amy,Sam等例句:He like s watching TV.他喜欢看电视。
She has lunch at twelve.她十二点吃午餐。
It look s like a cat.它看起来像只猫。
2.谁的亲戚谁的爸妈解释:例如Tom’s uncle, Amy’s aunt, Lingling’s sister , my father, my mum 等等例句:Tom look s like her mother. 汤姆看起来像她的母亲。
Amy’s aunt 或Uncle Wang often make s cakes.王叔叔经常做蛋糕。
My sister like s dancing . 我的姐姐(妹妹)喜欢跳舞。
3/4/ This 、that、the 、a、an,出现在单数前是三单解释:例如this book, that cat , a horse, an orange 等this/that /the /a/an 后面加上单数可数名词作主语,都属于第三人称单数。
be动词要用is.例句:This i s a pen.这是一支钢笔。
That is an eraser.那是一块橡皮擦。
第三人称单数[注意]a、下面两个动词变三单时,原词的元音部分的发音发生了较大的变化,要记忆。
如do/du:/ →does/dʌz/ ; say/sei/ → says /sez/ 。
b、以不发音字母“e”结尾的开音节词,如果尾音是[s][z]时加“s”后字母“e”发音与所加“s”一起读做[iz]。
如: close→closes [iz]。
在中文中第三人称单数的三个“他”写法不一样,读音却相同。
但在英语中,三个“他”既有不同的读音,也有不同的写法,分别是he, she, it。
在第三人称后不能使用动词的原形,而要在相应的动词后加s或es。
简单地讲,一个人就是单数,多于一个人就是复数。
在咱们汉语里,第三人称复数也就是常说的“他们”或者“她们”,英语中就是they.而“第三人称单数”就是指的“他”或者“她”,在英语中,相对应的就是he 或者she句子举例:第三人称单数: He is a student. (他是学生)第三人称复数: They are students.(他们是学生)以上只是一种帮助你理解的简单回答,第三人称还包括一些其他的方面,比如“it”等,这里就不多说了,希望你在学习中多多体会。
在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。
下面归纳一下第三人称单数的用法:一、人称代词he, she, it是第三人称单数。
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。
二、单个人名、地名或称呼作主语;是第三人称单数。
如:①Han Mei looks like her mother. 韩梅看起来像她的母亲。
②Beijing is in China. 北京在中国。
③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。

三单形式语法知识点一、知识概述《三单形式语法知识点》①基本定义:三单形式就是在一般现在时中,当主语是第三人称单数(he/she/it或者单个的人名、地名、物名等)的时候,动词要发生一定的变化。
比如,“like”这个动词,在主语是第三人称单数时,就变成“likes”。
②重要程度:在英语语法里非常重要,这是正确使用一般现在时表达句子意义的关键部分。
要是没掌握好三单形式,很多一般性描述第三人称单数的句子语法就会出错。
③前置知识:得先知道什么是第三人称,像he、she、it以及Jane、China这些所有单独表示一个人、地方、事物的。
还有一般现在时的基本概念,即经常发生的动作或者存在的状态。
④应用价值:在日常英语交流还有英语写作里都经常要用到。
比如描述一个人的习惯爱好,“He plays basketball every day.”(他每天打篮球),要是不懂三单形式就会写成“He play basketball every day.”,那句子就错了。
二、知识体系①知识图谱:在英语语法体系中,它是一般现在时这个分支中的一个重要规则部分。
②关联知识:与主语的单复数知识相关联,还和动词的时态知识有联系,因为不同的时态对于动词形式有不同的规则。
③重难点分析:- 掌握难度:对于初学者有点难,因为汉语里没有这样的动词变化习惯。
像我刚开始学英语的时候,老是忘记把动词变成三单形式,总觉得加个“s”或者“es”特别奇怪。
- 关键点:要能够准确判断主语是不是第三人称单数。
比如“the boys”是复数就不需要用三单形式,但是“the boy”是单数就得用。
④考点分析:在英语考试里是必考内容。
经常出现在选择题、填空题和书面表达中。
像是“Tom____ (go) to school by bike.”这种填空题,就得填“goes”,要是填“go”就错了。
三、详细讲解【理论概念类】①概念辨析:三单形式只用于一般现在时,而且是针对第三人称单数的主语才生效的动词变化形式。
一般现在时动词三单一般现在时的句子结构1、当句子表状态说明主语是什么或怎么样时句子结构为:主+BE动词,am, is, are,+其他.+BE动词+not+其他. 否定式为:主疑问句为:BE+主+其他,例: The twin sisters are from America.The twin sisters are not from America.Are the twins from America? 2、当谓语由实义动词充当~主语不是第三人称单数时~句子结构为:主语+动词原形+其它.否定式为:主语+don't+动词原形+其它.疑问句为:Do+主语+动词原形+其它,例: We speak Chinese.They don't speak Chinese.Do you speak Chinese? 3、当主语是第三人称单数时:句子结构为主语+动词,词尾加s或es,+其它.否定式为:主语+doesn't+动词原形+其它.疑问句式:Does+主语+动词原形+其它。
动词三单变化方法1. 一般情况下在动词后面加 s。
例如 read---reads, write---writes, like---likes, take---takes, see---sees,say---says, help---helps 等等。
2. 遇到以 -ch, -sh, -s, -x, -o 结尾的动词~加 es。
例如 teaches, washes, guesses, fixes, goes, does 等。
3. 遇到以“辅音字母+y” 结尾的动词~将 y 改为 i 后加 es。
例如 try---tries, study---studies, carry---carries 等。
4. 个别动词有特殊的变化形式:have---has, be---is。
