however, things are not always like this. "you never listen to me" is a complaint heard as often from children as parents. good communication helps children and parents to develop confidence, feelings of self-worth, and good relationships with others. try these tips:
teach children to listen... gently touch a child before you talk... say their name.
speak in a quiet voice... whisper sometimes so children have to listen... they like this.
look a child in the eyes so you can tell when they understand... bend or sit down... become the child's size.
practice listening and talking:talk with your children about school and their friends.
respect children and use a courteous tone of voice. if we talk to our children as we are good friends, our youngsters may be more likely take us as confidants.
use door openers that invite children to say more about an incident or their feelings. "i see," "oh," "tell me more," "no kidding," "really," "mmmmhmmmmm," "say that again, i want to be sure i understand you."
praise builds a child's confidence and reinforces communication. unkind words tear children down and teach them that they just aren't good enough.
children are never too old to be told they are loved. saying "i love you" is important. writing it in a note provides the child with a reminder that he can hold on to.
give your unpided attention when your children want to talk to you. don't read, watch tv, fall asleep or make yourself busy with other tasks when talking with kids.
all in all, as parents, we should respect our kids and listen to them, talk to them as friends. we should alwasys be there to share with kids their joys and sorrows.

第三人称单数
第三人称单数是英语中的一种语法,也称“三单”或“单三”,是语言中对对话双方外其它某一个人指示时使用的代词。第三人称是相对于对话是,某一句话中,言语发出方(第一人称)和言语的听受方(第二人称)以外的其它人称。单数是指该句中提到的其它人是一个人,相对于两个人(双数,在太平洋岛屿土著语言中广泛存在人称代词的双数)或更多人(复数)。如汉语中的“他”、“她”、“它”,英语中的he、she、it、him、her。在英语教学中,第三人称单数除了指英语中这一套代词外,也指这一套代词的相关语法。
1基本介绍
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,当动词在第三人称单数后时【she、he 、it、不可数名词和人名(一个人的)】,要根据其情况变化。通常加s/es 2变化规则
情况
一般情况
s 以s,x,ch,sh和o结尾 es 以,辅音字母,y结尾 变y为i, es 以f或者fe结尾 特殊情况
不规则
方法
示例 play—plays go—goes study,—studies have—has
变f或fe为v es,亦或直接加s(示例) wife,—wives 以o结尾 es do---does 3用法示例
首先,咱们要搞清楚第一、第二、第三人称各是什么。第一人称就是“我”和“我们”。第二人称是“你”和“你们”。第三人称单数是“他”、“她”和“它”,复数则是“他们”。
1、大多数实义动词在词尾加“s”在清辅音后发音为/ s / ;在浊辅音及元音因素后发音为 / z /。 如speak→speaks /s/ ; come→comes /z/ ; play→plays /z/ 。
2、以辅音字母加“y”结尾的动词,要先将“y”变为“i”然后再加“es”读/z/。 如study→studies /z/ ; fly→flies /z/
3、以“s、x、ch、sh”结尾的动词在词尾加“es”发音为/ iz / 。 如teach→teaches /iz/ ; watch→watches /iz/
4、以“o”结尾的动词,在词尾加“es”。 常出现的两个以“o”结尾的动词go和do后加“es”读/z/ 。 如go→goes /z/ ; do→does /z/
5、记住最为特别的be的三单is ,have的三单是has。
[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。
下面我们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、单数可数名词或“this/that/the 单数可数名词”作主语时,是第三人称单数。如:
①a horse is a useful animal. 马是有用的动物。 ②this book is yours. 这本书是你的。 ③that car is red. 那辆小汽车是红色的。 ④the cat is lucys. 这只猫是露茜的。
四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时,是第三人称单数。如: ①everyone is here. 大家到齐了。
②there is something wrong with the watch. 这块手表有毛病。 ③this is a pen. 这是一支钢笔。 ④that is an eraser. 那是一块橡皮擦。
五、不可数名词作主语时为第三人称单数。如: ①the milk is in the glass. 牛奶在玻璃杯里。 ②the bread is very small. 那面包很小。
六、当数字或字母作主语时,看作第三人称单数。如: ②“i” is a letter. “i”是个字母。[1]
