1、小学语法一般现在时态及第三人称单数（附练习及答案）第三人称单数问题一般现在时中，当主语是第三人称单数时，即常在动词原形后加-s或-es。第三人称单数变化，现归纳总结如下：1.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。2.单个人名、地名或称呼作主语；用第三人称单数。如：Han Mei looks like her mother.韩梅看起来像她的母亲。Beijing is in China.北京在中国。Uncle W

2、ang often makes cakes.王叔叔经常做蛋糕。3.单数可数名词或this / that / the/ a +单数可数名词作主语时，是第三人称单数。如：A horse is a useful animal.马是有用的动物。 This book is yours.这本书是你的。That car is red.那辆小汽车是红色的。 The cat is Lucys.这只猫是露茜的。4.不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时，第三人称单数。Everyone is here.大家到齐

3、了。 There is something wrong with the watch.这块手表有毛病。This is a pen.这是一支钢笔。 That is an eraser.那是一块橡皮擦。5.不可数名词作主语时为第三人称单数。如： The milk is in the glass. The bread is very small.6.当数字或字母作主语时，看作第三人称单数。如： 6 is a lucky number.6 I is a letter.发音规则动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同，请认真观察。1、大多数动词在词尾加“S”在清辅音后发音为s，在浊

4、辅音及元音后发音为 z。如：stopstops s ; makemakes sreadreads z ; playplays z2、以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读iz 如：flyflies z； carrycarries zstudystudies z; worryworries3、以“s, x, ch, sh”结尾的，在词尾加“es”，发音为iz 如：teachteaches iz; watchwatches iz4、以“o”结尾的动词，加“es”，读z 如：gogoes z dodoes z注：下面几个动词变为单数时，原词的元音部分的发音发生了较大的变

5、化，请注意记忆。 如：1、do du:does dz2、say seisays sez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：closecloses iz 一般现在时态一、一般现在时的用法:1、表示经常或者反复发生的动作. 如: 我每天吃午饭. I have lunch every day.2、还表示现在存在的一种状态. 如：我姐姐是一位老师My sister is a teacher.3、客观真理，客观存在，科学事实。例如：The earth moves around the sun.地球绕着太阳转。二、一般现在时态经

6、常与often（经常）sometimes（有时）always（总是）usually（通常）等频率词连用，也经常与every day（每天）, every week（每周）, every month（每月）, every term（每学期）, every year（每年）, once a week （一周一次），twice a year（一年两次）等表示时间的词连用。三、第三人称单数问题一般现在时中，当主语是第三人称单数时，即常在动词原形后加-s或-es。四、一般现在时分类：一般现在时态分为be 动词的一般现在时。1） be动词包括am，is，are. 中文为是， 这三个词的用法要随着主语的变化

7、而变化。 am 用于第一人称单数（I）; is 用于第三人称单数（he，she，it）; are 用于第一人称复数（we），第二人称单数和复数(you), 第三人称复数（they）。 可以记住以下顺口溜： am管 我， is管，她，它，他， are管大家。一般疑问句和否定句：把be 动词am，is，are 放在句首,回答时也要使用be动词；变为否定句时,把表示否定的not 放在 am is are 的后面, 其中可以简写为：is not- isnt ；are not- arent；am not 没有简写形式。注意：如果are not, is not放在句尾时，不能使用简写，必须写出整个单词。.

8、Am I a teacher? Yes, I am. (No, I am not.) Are you his friend? Yes, you are. (No, you are not.)Is she a nurse? Yes, she is. (No, she is not.)否定句为：I am not a teacher. You are not his friend. She is not a nurse.2）实义动词的一般现在时如果句子的动词不是be 动词 am is are 而是其他实义动词, 疑问句和否定句要借助于助动词do或者 does， 也就是说be 动词和实义动词原形不能同

9、时使用。 这里的 do，does 本身没有什么意义，只是帮助构成疑问句和否定句. 一般疑问句读时必须用降调.do和 does的使用要随着人称的变化而变化。请看下面两组句子，注意区分他们的共同点和不同点。I go to school every day. - I dont go to school every day.He goes to school every day. -He doesnt go to school every day.Do you go to school every day? -Does he go to school every day?Yes, I do. (No,

10、 I dont) -Yes, he does. (No, he doesnt)当主语是第三人称单数时，肯定句为：主语+动词的s形式+宾语否定句为：主语+助动词doesnt+动词原形+宾语疑问句为：Does+主语+动词原形+宾语肯定回答和否定回答也要使用助动词does.注：1）第三人称单数用了 does 后面就不用动词的s形式了,而用动词原形.2）变为疑问句,要在句首加do ; 变为否定句, 要在动词前面加do not, 可以简写为 dont.I.写出第三人称单数：wash_ match _guess_ study_ finish_ go_ snow_ carry_II.用所给动词的适当形式填空
